Warnings tell you about dangerousconditions, that could lead to death orserious injury to the user or patient, thatcan occur if you do not obey all of theinstructions in this manual.1. WARNING: You should ensure that the

performance offered by the pump is fit for theintended purpose. Failure to do so may resultin compromised function of the product,patient injury or user injury.

2. WARNING: Do not use a faulty pump. If thepump detects a fault when it is first turned on,or if it develops a fault during operation then acontinuous system alarm sounds. The pumpmust be referred to a suitably qualifiedtechnician or returned to Graseby Medical inorder to have the fault rectified.

3. WARNING: Before using the pump, it should beinspected for physical damage. The pumpshould not be used if damage is evident, andshould be returned to service personnel forrepair before being returned to use. Failure todo so may result in compromised function ofthe product, patient injury or user injury.

4. WARNING: Do not use the pump if you detectany cracks, chips and loose or bent parts, orif the buttons do not move in and out freelywhen they are pressed. Failure to do so couldcause inadvertent disconnection of the pumps.

5. WARNING: Do not push or pull on the pumps,or the IV pole may tip over or the pumps fallto the floor. Do not try to remove modularconnected pumps from the IV pole whilst theyare joined together. Either of these couldcause the administration set to separate fromthe fluid container thus spilling themedication, or the pumps themselves could bedamaged.

6. WARNING: Correct entry of data is essential inorder to ensure that the intended infusion isperformed. Before confirming any displayeddata when setting up an infusion, you shouldensure that it is correct. Failure to do so mayresult in compromised function of the product,patient injury or user injury.

7. WARNING: Dose-rate calculation requirescare in entering data. Refer to specific productdrug labelling for information on appropriateadministration techniques and dosages.Entering incorrect data may result in patientinjury or death.

8. WARNING: When delivering drugs in theepidural space, use only those medicationsspecifically indicated for epidural use.Epidural administration of other drugs couldresult in serious patient injury or death.

9. WARNING: The use of administration setsincorporating injection sites could lead to animproper or inappropriate infusion resulting inserious patient injury or death.

10. WARNING: Failure to clearly identify the pumpand administration sets could lead to animproper or inappropriate infusion resulting inserious patient injury or death.

11. WARNING: Remove any air to prevent airembolism. The presence of air within theinfusion can result in complications resultingin patient injury or death.

12. WARNING: To avoid over infusion, do notprime the infusion line when the admini-stration set is connected to the patient. Overinfusion can result in patient injury or death.

13. WARNING: The Occlusion alarm level must bechecked before starting an infusion to ensurethat it is appropriate for the infusion. Failureto do so may result in an unacceptably slowtime to Occlusion alarm, resulting in patientinjury or death.

14. WARNING: Prior to starting an infusion,inspect the fluid path for kinks, a closed clampor other obstructions. Failure to do so mayresult in the infusion not being deliveredcorrectly, resulting in patient injury or death.

15. WARNING: If using a blood pressure cuff abovethe patient’s venipuncture site take extra carein setting the Occlusion alarm pressures.Failure to do so may result in unnecessaryOcclusion alarms, resulting in patient injuryor death.

16. WARNING: The Occlusion detection systemmeasures downline pressure in the admini-stration set, but does not detect infiltration. Inaccordance with local protocol, you mustperiodically inspect the patient’s infusion sitefor signs of infiltration. Failure to do so mayresult in an unacceptably slow time toOcclusion resulting in patient injury or death.

17. WARNING: If an Occlusion alarm occurs,immediately clamp the line to the patient. Theninspect the fluid pathway to determine whathas caused the obstruction. An unintentionalbolus of medication can result in patient injuryor death.

18. WARNING: Do not run parallel infusion linesbelow the pump. Delivering a Secondaryinfusion means running a second line abovethe pump. Failure to do so may result in aninaccurate delivery of medication, resulting inpatient injury or death.

19. WARNING: Check the Secondary set carefully,since an occlusion above the pump on theSecondary line could cause the Primary fluidto be delivered instead of the Secondaryinfusion. Administering the wrong medicationmay cause serious patient injury or death.

20. WARNING: The Secondary volume to be infusedmust match the amount of fluid in thesecondary container. Primary flow resumeswhen the secondary container is empty. If thevolumes do not correspond, the wrong infusionmay be delivered which could cause seriouspatient injury or death.

21. WARNING: Correct management of batterycharging, as described in this documentationis essential to ensure that the pump canoperate on battery for the time specified.Failure to do so may result in compromisedfunction of the product or patient injury.

22. WARNING: If a backup alarm sounds, the pumpshould be immediately removed from thepatient and sent to be repaired by a GrasebyMedical qualified technician. Failure to do somay cause patient injury or death.

23. WARNING: Failure to use the power cordretainer means that the pump may beaccidentally or erroneously disconnected from

the mains. Although there is a battery backupin case this happens, the battery may not becharged sufficiently. Consequently, there is arisk of the pump not functioning which couldlead to patient injury or death.

24. WARNING: Do not open the pump housing.Refer all service faults only to qualifiedtechnical personnel. Opening the pumphousing may cause electric shock leading topatient or user injury or death.

25. WARNING: When the pump is carrying out aninfusion, to ensure that electrical safety ismaintained, only items of equipment thatconform to EN60950 are to be connected to theRS232 connector situated at the back of thepump, otherwise patient safety may becompromised.

26. WARNING: While Graseby Medical Limitedhave taken all reasonable steps to ensure thatthe pump operates correctly while underremote control, it is the responsibility of theperson who designs and implements thecontrolling device to ensure that the resultingsystem (pump and controlling device) is fit forits intended purpose. Failure to do so mayresult in compromised function of the product,patient injury or user injury.

27. WARNING: Use only Graseby Medicaladministration sets with this product. Failureto do so may result in compromised systemaccuracy leading to complications resulting inpatient injury or death.

C o n t e n t s

The information in this section isintended for technicians and cliniciansalready familiar with earlier versionsof the Graseby 500/505 volumetricpump. It summarises the changes tothe pump that appear with version 0.71of the pump software:• new menu,• new options,• new features that the menu and

options provide.To find out the software version of aparticular pump, check the instructionslabel on the right side of the pump. Ifthere are more than eight optionslisted, then the software version is 0.71or later.

For full details on how to use the pumpsee the Volumetric Instruction Manual.For information on configuring thepump, see the Technical User Manual,and for more detailed technicalinformation, obtain a copy of theVolumetric Service Manual.

New MenuA Technician Menu has been introduced,to simplify the configuration of eachpump. Some of the items on theTechnician Menu affect how the pumpbehaves; others control the options thatappear to the pump user when theypress the Options button to show theOptions menu. The configurable itemson the new Technician Menu are shownon page 12 of the Technical UserManual.

If the Technician Menu settings are leftat their factory defaults, the pumpbehaves as the previous version of thepump.

New features of version 0.71 softwareNew OptionsThe new options (and some of theprevious options) can be enabled on theTechnician Menu. This means that theycan appear when appropriate, but canbe disabled if not required. On theinstruction label on the pump, Optionsnumbered 1 to 8 are the ones thatappeared in previous versions of thepump software. The additional newoptions shown on the label are:• Primary infusion Minimum• Primary infusion Maximum• Primary Max Volume to be infused• Secondary/Bolus Minimum• Secondary/Bolus Maximum• Secondary/Bolus Max Volume to be

infused• KVO Rate• Drug Library to allow selection and

display of a drug label.

New featuresThe new menu and new options inversion 0.71 software provide a numberof new features. These fall into thefollowing broad areas:• Infusion mode features• Safety features• Display features• Servicing features.

Infusion mode featuresUsing the Technician Menu, the pumpcan be configured:• to stop at the end of a Secondary

infusion, or to continue infusing andautomatically switch to theprogrammed Primary rate;

v i V o l u m e t r i c I n f u s i o n P u m p I n s t r u c t i o n M a n u a l


• to allow a Bolus infusion to beprogrammed where the volumeinfused is deducted from theprimary infusion volume to beinfused; to highlight this feature,the key previously called“Secondary” is now called“Secondary/Bolus”

• to allow the user to set a KVO ratefor an infusion, or remain at thedefault rate configured for theparticular pump;

• to use the Occlusion Alarm levelspecified for an infusion, or remainat the configured default alarmlevel;

• to allow access to a previouslyprogrammed Dose-Rate Calculationinfusion when the pump is switchedon (Dose-Rate Calculation recovery),or display the standard messages.

Safety features• a timeout safety feature has been

added. This means that whenmessages are not actioned withinthe timeout period, for examplesetting a value, the pump reverts tothe previous display.

• safety keypad lockout, this featureis only activated when operating thepump on AC power. It allows theuser to lockout the keypad aftersetting the pump up for use, so thatit can be ready for infusion at alater time.

Configurable safety features that can becontrolled on the Technician Menu are:

• automatic keypad lock after oneminute, to prevent malicioustampering, and increase patientsafety;

• preset rate and VTBI limits, so thatInfusion Rate and Volume to be

Infused are limited to a suitablerange; this prevents values beingprogrammed accidentally which areinappropriate for infusions inparticular environments (such asepidural infusions, or paediatricapplications).

Display features• configured parameters are shown on

the Message Display when the pumpis switched on.

Configurable display features that can becontrolled on the Technician Menu are:

• the backlight may be activated whenthe keypad is touched, or kept onpermanently;

• one of 30 preset drug labels may beselected and viewed as requiredduring an infusion;

• the display of micrograms (whenprogramming an infusion usingdose-rate calculation) can be shownas ‘µg’ or ‘mcg’;

• the time display may include thesuffix GMT, or the suffix can besuppressed if it is not appropriate.

Servicing featuresOn the Technician Menu, the pump canbe programmed with a pump ID to suitthe hospital protocol, and a service duedate:

• the ID, for example the serialnumber of the pump, or analphanumeric pump name, isdisplayed each time the pump isturned on;

• when a Service Date is set, the dateis displayed each time the pump isswitched on. An alarm sounds whenthe date is reached.

Introduct ion to the 500/505 pumps

The Model 500 is designed for use in allareas, as it can be programmed with aninfusion rate of up to 999 millilitres perhour, and a maximum volume to beinfused of 9999 millilitres.

The Graseby Medical 500 and 505Volumetric pumps are designed for usein infusion therapy in both venous andarterial infusions. They offer bothstandard and optional featuresbringing accurate fluid delivery to thepatient.

This makes them ideal for use ingeneral care, home care, and intensive/critical care areas.

The Model 500 and Micro 505 pumpsare very similar in design. Thedifferences are in colour, graphics andin the maximum rate and volume to beinfused that can be programmed for aninfusion.

Model 500 Volumetr ic pump

Read the entire contents of thismanual carefully before using thepump.

Micro 505 Volumetr ic pump

The main features of the pumps aredescribed starting on page 1-3. For fulldetails on the differences between the500 and 505, see the Specificationsection at the end of this manual.

The Micro 505 is designed for use inpaediatric/neonatal environments andfor fluid restricted patients. It can onlybe programmed with an infusion ratebelow 100 millilitres per hour, and themaximum volume to be infused is 999.9millilitres.

I n t r o d u c t i o n G r a s e b y M e d i c a l L t d .

Both the Model 500 and the Micro505 pumps may be used for epiduraladministration.

AnaestheticsEpidural administration ofanaesthetics is limited to short-term(not to exceed 96 hours) infusion, withindwelling catheters specificallyindicated for short-term delivery ofanaesthetic drugs.

AnalgesicsEpidural administration of analgesicsis limited to use with indwellingcatheters that are specifically indicatedfor short or long term delivery ofanalgesic drugs.

Epidura l administ rat ionTo prevent infusion of drugs notindicated for epidural use and to avoidinappropriate delivery rates whenusing the pump for epiduralapplications:

• use the pump’s Maximum Rateoption, to set a maximum infusionrate of 20 mL/h on a pump to beused for epidural administration.This feature is described fully inChapter 3, Options;

• do not use IV administration setswhich contain injection sites;

• differentiate the pump and IV setbeing used for epidural delivery fromthose being used for other routes ofadministration. A yellow EpiduralLabel Set for the VolumetricInfusion Pump (part number TPF-00306) is available from GrasebyMedical. The labels should be stuckon the front, top and sides of thepump to help staff to identify apump that is dedicated to epiduralapplication.

WARNING: The use of administration setsincorporating injection sites could lead toan improper or inappropriate infusionresulting in serious patient injury ordeath.

WARNING: Failure to clearly identify thepump and administration sets could leadto an improper or inappropriate infusionresulting in serious patient injury ordeath.

WARNING: When delivering drugs in theepidural space, use only thosemedications specifically indicated forepidural use. Epidural administration ofother drugs could result in serious patientinjury or death.

Pump fea turesThe main features of the 500 and 505pumps are listed below:

Easy to use featuresThe pumps have been designed to beeasy to use:

• they are easy to set up and operate,yet with all the advanced featurestypically associated with the morecomplicated infusion systems;

• they have a straightforward keypadand an easy-to-read message display;

• the unique air-in-line removalsystem allows clearing of bubbles inthe line by simply opening andclosing the door: air is preventedfrom going beyond the cassette; thisincreases patient safety, minimisesthe risk of infection and savesoperator time;

• they can be used at the bedside or astransportable equipment; using theinternal battery which also switchesin automatically if the pump isbeing used on mains power and thisis interrupted.

Use of administration setsThe pumps can only be used withGraseby Medical administration sets.These administration sets have thefollowing features:

• all Graseby Medical administrationsets incorporate a safety clip toprevent accidental free flow whenthe administration set is removedfrom the pump;

• when used with Graseby Medicalblood administration sets thepumps deliver blood and bloodproducts without significanthaemolysis of red blood cells.

Infusion mode features• accurate (± 2%) fluid delivery;• the pumps can be configured to stop

at the end of a Secondary infusion,or automatically switch to infuse atthe programmed Primary rate;

• a Bolus infusion may beprogrammed so that the volumeinfused is deducted from theprimary infusion volume to beinfused;

• KVO rate may be specified for aninfusion, or remain at the defaultrate for a particular pump;

• the pumps offer a quick rate changefeature for complete titrationcapability;

• automatic delivery of a secondarymedication (if a secondary infusionhas been set up).

Safety featuresThe pumps have been designed with ahigh emphasis on safety:

• there is an optional automatickeypad lock which preventsinadvertent operation and increasespatient safety;

• the keypad can also be lockedmanually at any time;

• a pump may be configured so thatits Infusion Rate and Volume to beInfused are limited to a suitablerange; this prevents values beingentered accidentally which areinappropriate for infusions inparticular environments (such asepidural infusions).

• the pumps have indicators that arelit to show if they are running onbattery or mains;



• when using the battery, a test isperformed on power-up and the levelis shown on the display; manualtesting is also available;

• the pumps have an RS232 interfaceallowing connection to a computerfor external monitoring.

Display featuresApart from the standard display,pumps can be configured to show extrainformation, either as a standardmessage display or by pressing a key totoggle the display.

Standard displays are:

• the volume infused in the currentinfusion;

• the infusion rate;• the Volume to be Infused in the

remainder of the infusion.Additionally:• the rate and volume to be infused

displays are automatically adjustedto make them easy to read in anylight;

• the time remaining in the presentinfusion may be viewed;

• the total volume of fluid delivered toyour patient since the totaliser waslast cleared to be viewed; alsodisplayed with the total volume isthe total time (hours and minutes)that the pump has been in use sincethe totaliser was last cleared;

Using configurable displays:• the backlight may be activated when

the keypad is touched, or kept onpermanently;

• optionally, one of 30 preset druglabels may be selected and viewedas required during an infusion.

Occlusion Pressure featuresThese features increase safety ininfusing fluid, particularly in criticalcare areas such as neonatal andpaediatric care:

• when setting occlusion alarms, threestandard occlusion alarm settingsbetween 100 and 500 mmHg can bemade; see the Specification sectionat the end of this manual for fulldetails of the occlusion alarmvalues;

• the occlusion pressure alarm settingwhen the pump switches on isconfigurable; you can change thesetting for a particular infusionusing the Occlusion AlarmSetting key;

• when an occlusion alarm sounds, thepumping mechanism backs off toreduce downline back pressure andbolus potential (bolus potential isapproximately 0.3 mL regardless ofthe rate and the administration setused);

• when an occlusion is detected, thepump does not give an occlusionalarm immediately, but only alarmsif the occlusion pressure continuesto exceed the occlusion threshold forup to 10 seconds; however, if suchtemporary occlusions persist, thenthe occlusion alarm is generated;this helps to avoid nuisanceocclusions.



1 — 5


Special infusion featuresThe pumps have a number of specialinfusion options:

• a Volume over time option allowsthe user to set the volume to beinfused and total time for theinfusion, the pump automaticallycalculating the infusion rate;

• a Dose-rate calculation option whichallows automatic calculation of theinfusion rate by entering infusiondose; patient weight (kg or lbs); drugamount in fluid container (in MG,Gm or mcg units), and volume offluid in the container, in mL;

• a Rate Tapering option allowsautomatic tapering of the infusionrate (either up or down) foradministration of IV nutrition.

Multiple use featuresWhen multiple infusion lines arerequired, two or three pumps can befitted together:

• modular side rails and hooks meanthat one, two, or three pumps maybe connected to a single IV pole; thisprovides space saving;

• the modular connection system hasa safety feature which ensures thatthe first pump must be correctlyattached to an IV pole before thesecond and third pumps can beconnected.

Servicing featuresThe pumps have been designed with anumber of features for Biomedicalengineers:

• a Service Due Indicator, allows aservice date to be set, which isdisplayed on power-up with analarm;

• special menus are provided to aid intesting, troubleshooting and service;

• the last 200 events are recorded andavailable on these menus;

• downloading of the pump history ispossible using the RS232 port witha special optional kit (Part no 0150-0673).

Together with the ability to configurethe pump using the Technician Menu,these features offers greatermanagement flexibility.

Instructions for using these functionsappear in the Technical User Guide andthe Volumetric Service Manual.

Optional featuresSome pumps are optionally fitted witha Nurse-Call Feature which allows apump to be connected to a hospitalnurse call system and signal alarmsoccurring in the pump.

Note: This feature is not available inall countries.

Connect ing the pumps to an IV poleIn use, Graseby Medical recommendthat the pump should be connected to asuitably balanced IV pole using the poleclamp as illustrated in the diagram onthe opposite page.

The diameter of the pole must bebetween 1.2 cm and 3.8 cm (0.5 and 1.5inches).

To provide maximum stability whenusing the modular connection system,ideally, the IV pole should have 6wheels and a low centre of gravity. Thebase diameter should be 56 cm (22inches).

Attaching a single pump to an IVpoleTo attach the pump to a suitablybalanced IV pole:

1. Loosen the screw on the pole clamp.2. Hold the pump by the handle and

slip the arms of the pole clamp ontothe pole.

3. Tighten the screw on the pole clampto firmly attach the pump to thepole.

Attaching more than one pump toan IV poleWhen multiple infusion lines arerequired, you can connect up to threepumps to a single pole using the hooksand rails that make up the modularconnection system.

As all pumps have connectors on bothsides, you can use any one as the centre,

left, or right pump.

This diagram shows how three pumpsmay be connected together using theVolumetric’s modular connectionsystem:

Inspecting the modularconnectionsBefore connecting the pumps, you mustcheck that the modular connectionparts are all in good condition:

1. Carefully inspect the modularconnection system for damage,including cracks, chips, loose or bentparts.

2. Press the disconnect buttons severaltimes to make certain that thebuttons move in and out freely.

WARNING: Do not use the pump if youdetect any cracks, chips and loose or bentparts, or if the buttons do not move inand out freely when they are pressed.Failure to do so could causeinadvertent disconnection of thepumps.



How to connect pumps togetherOnce you have inspected the modularconnection system as described in theprevious section, connect the pumps asfollows:

1. Clamp the first pump to the IV pole.This is now the "centre" pump.

Note: As you tighten the screw on thepole clamp, you automatically adjustthe modular connection hook anddisconnect button. Once the pump issecurely attached to the pole, the hook isin the correct position to allow you toconnect further pumps.

2. Take the second pump, grasping itby the handle and hold it so that themodular connector rails are directlyabove or below the connector rails ofthe centre pump.

3. Engage the edges of the modularconnector rails and slide the secondpump up or down until it isconnected to the centre pump. Whenthe connection is secure, you hear adistinct click.

4. Before releasing the handle of thesecond pump, double-check that theconnection is secure by moving thepump up and down and exertingpressure on the top of the pump.

To attach a third pump to the otherside of the first pump, repeat steps 2, 3and 4.

Moving an IV pole with pumpsconnectedIf you need to move the IV pole once thepumps are attached, always ensurethat you grasp the IV pole with onehand and steady the pumps with theother hand if necessary.

Disconnecting modularconnected pumpsYou must always disconnect modularconnected pumps one by one beforeremoving the centre mounted pumpfrom the IV pole.

Disconnect the left and right handpumps from the centre mounted pumpas follows:

1. Grasp handle of pump to beremoved.

2. Lift the pump slightly.3. Press the disconnect button and

slide the pump up or down todisconnect from the centre pump.

4. Place the pump in a location whereit will not be damaged.

WARNING: Do not push or pull on thepumps, or the IV pole may tip over orthe pumps fall to the floor.Do not try to remove modular connectedpumps from the IV pole whilst they arejoined together.Either of these could cause theadministration set to separate from thefluid container thus spilling themedication, or the pumps themselvescould be damaged.

Note: If the connection is loose, or thepumps seem to wobble, disconnectthen carefully reconnect them,making sure both edges of themodular connectors engage. Do notuse pumps where the connection isloose, but return them to a suitablyqualified technician for repair.

Switching the pump on and off

To switch on the pump you can doeither of the following:

• press the On/Off key• open the front door by lifting the

latch.

Switch on in Quiet Pump modeIf you want to use the pump withoutany key clicks and also suppress thenon-insistent alarms, you can switch onin "quiet pump" mode:

1. Press the Silence key and keep itpressed down.

2. Press the On/Off key.Note: Quiet Pump operation iscancelled when you turn off the pump.

Self testWhen you switch it on, the pumpcarries out a series of tests to ensurethat all components are functioningcorrectly. If any electrical or mechanicalproblems are detected, or if anypotential problems are detected, then a

message is displayed and the alarmsounds. See Chapter 4, Troubleshootingfor more details on handling alarms.

Message Display at Switch onThe messages displayed when youswitch on the pump depend on whichfeatures have been enabled on thepump and whether or not it isconnected to the AC mains supply.

If all the pump options have beenenabled, the pump displays messagesto provide you with the followinginformation about itself:

• Pump Identifier• Drug Label• Primary Min Rate and Max Rate• Primary Max VTBI• Battery gauge (displayed only if the

pump is disconnected from the ACmains supply)

• Service due date.

After switching onWhen the pump has completed its selftests, it is ready for you to program,load a cassette (see page 2-18), or startan infusion. You see a screen somethinglike this:

Before switching the pump on, visuallycheck for any cracks on the case, ordamage to any part of the pump or itsconnectors. Plug the AC mains cord into

Switching on

an AC mains supply if possible. Ifnecessary, the pump can be run on itsinternal batteries, see Using the pumpon batteries, later in this chapter.

Note: If the pump is switched off andconnnected to AC power and thesaftey keypad lockout feature isactive, the pump cannot be switchedon via the keypad, see Safety keypadlockout, page 2-22.



Switching of fFor safety reasons, the front door mustbe properly closed and any infusionmust be on Hold before you switch offthe pump.

Using the pump on bat teryThe pump contains an internalrechargeable battery. However, ineveryday use, the pump should beconnected by its cord to a suitable ACmains supply, if one is available. Thebattery is then kept fully charged, andwill continue to be charged whilst thepump is infusing.

The pump automatically uses the battery:

• if you switch on whilst the powercord is unplugged, or

• if the AC power fails whilst thepump is operating.

Switching on using the batteryWhen you switch on the pump, if it isbeing powered by internal battery:

• you need to hold down the On/Offkey to turn the pump on. If the pumpis operating on the AC mainssupply, it switches oninstantaneously when you touch theOn/Off key;

• there is a short pause whilst thepump carries out the Battery Testand displays the Battery Gaugescreen to indicate the currentbattery capacity:

Note: The battery is always testedwhen the pump is switched on, eventhough the Battery Gauge is notdisplayed during Dose-RateCalculation, DRC Recovery or RateTaper infusion start up.

Testing the batteryAt any time when operating on battery,you can check the battery capacity bycarrying out the Battery Test describedin Chapter 3, Options.

Operating using the batteryDuring operation of the pump onbattery:

• the yellow Battery indicator is lit• the Message Display light turns off

if the pump is left on Hold, unlessyou have set the ‘Backlight on’option, described in Chapter 3,Options.

Low batteryWhen you switch on the pump, andduring operation, the pump warns youwhen the battery capacity is low. If yousee the yellow Battery indicatorflashing whilst the pump is infusing,you should plug the power cord into theAC mains supply as soon as possible.

• If the pump is running an infusion,press the Hold key;

• if the front door of the pump is open,close it with the latch;

• then press the On/Off key.

Low battery alarmsWhen approximately one hour ofoperation remains, the pump sounds analarm and displays this message:

If you see this message, plug the powercord into the AC mains supply as soonas possible.

If you decide that you must continue touse the pump on battery, anotheralarm sounds approximately half anhour before it is fully discharged.

This message is displayed:

It is essential that the pump is pluggedinto the AC mains supply at this point.

Recharging the batteryTo charge the battery, plug the powercord into the AC mains supply.

It takes approximately 10 hours torecharge a completely depleted battery.

CapacityA new, fully charged battery willoperate the pump for approximately 6hours at 100 mL/h (99.9 mL/h on Micro505).

The battery may discharge morequickly if the battery has aged and is ina poor condition even though it wasrecently charged.

Pump in storageYou should connect the pump to the ACmains supply to charge the batteryevery three months, even when thepump is not in service. This helps tomaintain the life of the battery.

WARNING: Correct management ofbattery charging, as described in thisdocumentation is essential to ensurethat the pump can operate on battery forthe time specified. Failure to do so mayresult in compromised function of theproduct or patient injury.

Sounds on the Vo lumetr icThe Volumetric pump makes a 'click'sound as you press each key. It alsosounds an audio alarm to alert you to acondition that requires attention on thepump: either an insistent (three-tone)or non-insistent (two-tone) alarm. Theclick and non-insistent alarm do not

sound if the pump is switched on inQuiet Pump mode. See next page. As afurther safety feature, the Volumetricemits a high-pitched system alarm toindicate a problem requiring theattention of a Graseby Medicalqualified technician.

Audio alarmWhen the Volumetric pump requiresattention, it uses an audio alarm toindicate that there is a problem.

Whilst sounding the alarm, it alsodisplays a message to explain theproblem. A full list of all the alarmmessages, their possible causes andhow to solve the problem is explainedin Chapter 4, Troubleshooting.

This section explains the differenttypes of alarm sounds made by thepump.

You may hear three types of alarm fromthe Volumetric:

• insistent• non-insistent• continuous (backup alarm).

Insistent alarmThis type of alarm indicates that fluiddelivery has stopped, or cannot bestarted. It alerts you to a condition thatmust be corrected before the infusioncan be started, or continued, forexample if an occlusion is detected.

The insistent audio alarm consists ofthree tones: two high-pitched and onelow-pitched, repeated at two-secondintervals.

To silence an insistent alarm, press theSilence or Hold key. The alarm willrecur unless you correct the problem asdescribed in Chapter 4, Troubleshooting.This chapter describes each alarm, itscause and action to take.

Non-insistent alarmThis type of alarm alerts you to acondition that needs attention, but hasnot caused the infusion to stop. Forexample, you hear a non-insistentalarm if the pump is running onbatteries and the batteries are low, orif the infusion has switched to a KVOrate.

The non-insistent audio alarm consistsof two tones, one high-pitched and onelow-pitched, repeated at two-secondintervals. To silence this type of alarm:

• press the Silence or Run key tosilence the alarm without stoppingfluid delivery;

• press the Hold key to silence thealarm and stop fluid delivery.

Note: In Quiet Pump mode, there is noaudio alert for certain non-insistentalarms. See the next page for moredetails.



2 — 1 1


In some circumstances, it may bedesirable to operate the Volumetricwithout the associated sounds.

For safety reasons, you cannot turn offthe insistent or continuous alarms, butif necessary you can operate the pumpwithout the key-press 'click' sound andcertain non-insistent alarms. This iscalled a 'Quiet Pump' infusion.

To run a 'Quiet Pump' infusion:

1. Ensure that the pump is turned off.2. Press Silence and keep it held

down.3. Turn on the pump with On/Off.The keypad click and non-insistentalarm sound is now off. The pumpremains in Quiet Pump mode until youswitch off and then on again.

Quiet Pump mode

Silent alarms in Quiet Pump modeWhen running the pump in Quiet Pumpmode, certain alarms associated with aSecondary infusion are silent. Thealarm is silent in the followingcircumstances:

• when the pump automaticallyswitches from Secondary to Primarywhen the Secondary infusion iscomplete;

• when you program the Secondaryinfusion, but press the Primary keythen the Run key without runningthe Secondary infusion;

• when you press Run to start theSecondary infusion with the Volumeto be Infused set to zero.

Alarms and computer controlIf a pump is being run under computercontrol, you can silence it from thecomputer. However, you must resolvethe problem causing the alarm on thepump.

WARNING: If a backup alarm sounds, thepump should be immediately removedfrom the patient and sent to be repairedby a Graseby Medical qualified technician.Failure to do so may cause patient injuryor death.

Continuous - backup alarmIn addition to the insistent and non-insistent operational alarms, theVolumetric pump has a fail-safebackup alarm system. This has adistinctive high-pitched tone:

• should the audio alarm system fail,then the pump sounds the backupalarm, with a 1.5 second pausebetween alarm tones;

• should an electromechanical systemfailure occur, the pump sounds thebackup alarm continuously.

If you hear the backup alarm sounding,you should immediately remove thepump from the patient and have itrepaired by a Graseby Medicalqualified technician.



Types of in fus ionHospital protocols dictate how thePrimary, Secondary and / or Bolusfeatures are used, and the pump shouldbe configured to conform with theseprotocols.

This section summarises the typicaluse of these features of the pump.

For a Primary infusion, you set up thepump to deliver solution from a singlecontainer. This diagram shows anexample of how a pump looks when setup for a Primary infusion using aStandard administration set (8C-820)

The pump’s Volume to be InfusedDisplay shows the remaining Volumeto be Infused and on its MessageDisplay the pump shows the totalinfused so far.

For full details on how to set up aPrimary infusion: see Setting up aPrimary Infusion, page 2-16.

P r i m a r y

Using the pump, you may carry out:

• a Primary infusion

• a Primary and a Secondary infusion

• a Primary and a Bolus infusion.



2 — 1 3


Secondary

For a Primary and a Secondaryinfusion, two containers are used:

• one to deliver the Primary infusion,for example, a hydration solution;

• a second to deliver an additionalinfusion, for example an antibioticdose; this is sometimes called a“piggyback” infusion.

The pump keeps separate totals for thePrimary and Secondary infusions: thetotal infused in the Secondary infusionis not deducted from the PrimaryVolume to be Infused.

The pump can be configured to work inone of two ways at the end of theSecondary infusion: see Ending aSecondary infusion, over the page.

For full details on how to set up aSecondary infusion:

• first follow the steps in Setting up aPrimary Infusion, page 2-19;

• then see About Secondary Infusions,page 2-26.

Secondary infusion with BolusenabledThe pump can be configured, using theTechnician Menu, to offer a Bolusinfusion as an alternative to theSecondary infusion. If the Bolus featureis enabled, you can:

• run a Secondary infusion, where thevolume infused is not deducted fromthe Primary Volume to be Infused

or• run a Bolus infusion, where the

volume infused is deducted from thePrimary Volume to be Infused.

Pr imary and Secondary

Primary



When the Bolus feature is configured,each time you press the Secondary/Bolus key, the Message Display shows:

At this point, you would press 3 toenter Rate and Volume to be Infusedfor the Bolus, or to view the totals forthe Bolus infusion.

For full details on how to administer abolus infusion, see Running a BolusInfusion on page 2-31.

With the pump configured to offer theBolus feature, you can carry out a Bolusinfusion as an alternative to theSecondary infusion.

A Bolus infusion may be administeredat a different rate, with the volume tobe infused entered separately to thePrimary volume, just as for aSecondary infusion.

However, for a Bolus infusion, theVolume infused is deducted from thePrimary Volume to be Infused.

At the end of the Bolus, the pumpreverts to the Primary infusion at thepreviously programmed Primary rate.

The Secondary Stop feature, if enabledhas no effect at the end of a Bolus.

Primary and Bolus

The Secondary Stop feature in theTechnician Menu controls how thepump works when the Secondaryinfusion is complete.

• With Secondary Stop disabled, thepump automatically reverts to thePrimary infusion at the previouslyprogrammed rate, so that there is acontinuous flow. When the Primaryinfusion starts a non-insistentalarm sounds.

Ending a Secondary infusion• With Secondary Stop enabled, the

pump stops and sounds an alarmuntil you manually silence it andstart the Primary infusion.

The ef fect o f Opt ions set t ings oninfusionsSome of the Options settings can affectthe way you program the infusion, whatyou can do during the infusion, or theway the pump behaves. For example, ifthe pump has the appropriate Optionsenabled on the Technician menu, youmay choose to:

• turn on the Message Displaybacklight

• set the KVO rate• select a Drug Label• program a Dose-Rate Calculation,

Volume Over Time or Rate Taperinfusion.

Infusing with Rate and VTBI l imits enabled

However, the settings which may mostaffect the way you program an infusionare Rate and VTBI limits. Such limitsrestrict the values you can use duringan infusion and their use is describedbelow.

If you need to make any changes tothese Options settings, you must do sobefore programming the infusion. SeeChapter 3, Options for full details.

If the features for setting limits areenabled on the Technician Menu, thelimit values can be set or examinedusing the Options key. They can be setindependently for Primary andSecondary infusions and may not all beenabled. If Primary Rate or VTBIlimits are enabled, you can also see thesettings displayed after the pump isswitched on.

When limits are enabled, you cannotrun an infusion with a Rate or Volumeto be infused set outside the limits.Also, you cannot change the rate whilerunning to go outside the limits. If youtry to do this, or if you program a valueoutside the limits and then press theRun key, you see the message:

Wherever possible check or set thelimits before you program the infusion,especially if you might have to give aSecondary infusion or a Bolus. Theeasiest way to check Primary infusionsettings is to look at the messagedisplay when you switch the pump on.To check Secondary infusion settings,you must use the Options key. Settinglimits is described in Setting Rate andVTBI limits on page 3-29 in Chapter 3,Options.

Limits are enabled and set for a safetypurpose (for example, where the pumpis used for Epidural administration). Ifyou are likely to be in a situation whereyou have to give an infusion in anemergency, ensure that when a pump isswitched off, the limits are left withsafe value settings.



Note: A thick solution in this case maybe certain cytotoxic agents, lipid-basedfluids and other viscous solutions, forexample Total Parenteral Nutrition.

Height of solution container abovethe pumpIf necessary, adjust the height of thepole so that the bottom of the solutioncontainer is between 15 cm and 30 cm(between 6 inches and 12 inches) abovethe top of the pump

On Model 500, 30 cm (12 inches) may berequired for rates over 500 mL/h.

On both Model 500 and Micro 505,30 cm (12 inches) may be required whenusing thick solutions and/or60 drops/mL sets.

Sett ing up a Primary Infusion

Prepare the solut ion

Using an aseptic technique, prepare thesolution container and prime theadministration set following theinstructions provided with the set. As aguide:

1. Remove the solution container fromits packaging and remove the capfrom the fluid outlet.

2. Remove the administration set fromits packaging and close the rollerclamp.

3. Remove the cap from the spike onthe administration set and insertthe spike into the fluid outlet on thesolution container.

4. Hang the container with theadministration set on the IV poleand ensure that the container is thecorrect height above the pump.

To set up and run a Primary infusionthe main steps are:

• attach the pump to the IV pole,described on page 2-5;

• set the Options for the infusion ifappropriate, particularly Rate orVTBI Limits if they are enabled asdescribed on page 2-15;

• prepare the solution;• prime the administration set;• load the administration set into the

pump;• program the infusion;• start the infusion.

WARNING: Correct entry of data isessential in order to ensure that theintended infusion is performed. Beforeconfirming any displayed data whensetting up an infusion, you should ensurethat it is correct. Failure to do so mayresult in compromised function of theproduct, patient injury or user injury.



2 — 1 7


With the solution container hanging onthe IV pole and the administration setspike inserted into the container, primethe administration set as follows:

Prime the administrat ion set - Example1. Squeeze the drip chamber and fill

until it is at least one third full. Thedrip chamber may fill completelyduring loading and/or an infusion.This will not adversely affect thefluid delivery or the operation of thepump.

2. Hold the cassette inverted, so thatthe roller clamp is above thecassette, as shown here.

3. Slowly open the roller clamp toallow the solution to flow throughand prime the cassette and the line.You can control the flow by movingthe roller clamp as necessary.

4. When the entire set is primed, closethe roller clamp.

You must always follow the Instructionsfor Use that accompany theadministration set to be primed. Thissection shows an example to explainthe basic priming steps to be carriedout on an administration set without abi-directional check valve, filter,injection site or c-clamp.

WARNING: Remove any air to prevent airembolism. The presence of air within theinfusion can result in complicationsresulting in patient injury or death.

WARNING: Use only Graseby Medicaladministration sets with this product.Failure to do so may result incompromised system accuracy leading tocomplications resulting in patient injuryor death.

WARNING: To avoid over infusion, do notprime the infusion line when theadministration set is connected to thepatient. Over infusion can result in patientinjury or death.



When you switch the pump on, theOcclusion Alarm setting is always thesame, and is defined by the TechnicianMenu configuration setting.

Before an infusion, always check, and ifnecessary, change the setting to suitthe infusion by pressing the OcclusionAlarm Setting key. Continue pressingthe key until you see the setting youwant. Never use a Low setting withhigh infusion rates.

For full details, see Change theOcclusion Alarm setting, on page 2-24.

WARNING: The Occlusion alarm levelmust be checked before starting aninfusion to ensure that it is appropriatefor the infusion. Failure to do so mayresult in an unacceptably slow time toOcclusion alarm, resulting in patientinjury or death.

See the Specification section at theend of this manual for details on thepressure values for High, Mediumand Low settings.

WARNING: Prior to starting an infusion,inspect the fluid path for kinks, a closedclamp or other obstructions. Failure to doso may result in the infusion not beingdelivered correctly, resulting in patientinjury or death.



During the infusionThis section explains the mainactivities you may want to carry outonce you have started the infusion.

When the infusion is running, you can:

• see the progress of the infusion fromthe information shown on thedifferent displays on the pump;

• change the infusion rate;• lock the keypad to provide security

on the pump;

• display the drug label (if thisfeature is enabled);

• stop the infusion.If you press Hold to stop the infusion,you can:

• change the occlusion alarm setting(see page 2-24);

• set up and start a Secondaryinfusion (see page 2-26).

I f the infusion wi l l not start runningThis will only occur if you have one ormore of the following features enabledon the Technician menu:

• Min and Max Rate;• Max VTBI.If you have entered a rate which isoutside the set limits, or a VTBI whichis greater than the maximum, when youpress Run you see the message:

and an alarm sounds. The Rate orVTBI display also changes to the oneused before you programmed theinfusion.

If this happens, you should:

1. Silence the alarm.2. Check the Rate or VTBI display to

see which has changed to find outwhich limit has been exceeded.

3. Check the prescription.4. Check the Min and Max Rate and

Max VTBI settings by pressing theOptions key until each is displayed.

5. Make corrections as necessary.6. Press Run to start the infusion.

If you do not complete the rate changewithin 10 seconds, an alarm soundsand the rate reverts to the previousrunning rate, followed by a message totell you the change has not beencompleted.

If rate limits are enabled, and youenter a rate that is outside those set,an alarm sounds and you see:

The pump continues at the previousrate. Silence the alarm and check thecurrent settings using the Options key.If you need to change the rate limit, youmust first put the pump on hold.

Message DisplayThe Message Display starts at zero andcounts up in mL to show the volumeinfused so far, for example:

Rate display and Pumping indicatorThe Rate display shows the infusionrate. The Pumping indicator is ahorizontal line located at left of the Ratedisplay.

The indicator moves to show that thesolution is being infused. The speed of

the Pumping indicator isapproximately proportional to theinfusion rate.

Volume to be Infused displayThe Volume to be Infused displayinitially shows the programmedvolume. During the infusion, it countsdown to show the volume remaining forthis infusion.

Original volume to be infusedTo find out the original programmedVolume to be Infused, add the amountin the Volume to be Infused display tothe amount in the Message Display.

In fusion informat ion d isplays

Whilst the pump is running, you canchange the infusion rate. For example,you may need to adjust the initial rateonce the infusion is established.

You can also stop the infusion and thenchange the rate, but the ability tochange without stopping the delivery ofthe solution is especially importantwith some drugs, for example,vasoactive drugs.

You can carry out a running rate changeon Primary or Secondary infusions.

Once the infusion has started, to entera running rate change:

1. Press Rate.2. Enter the new rate using the

Stop the infusion

If an occlusion is detected, the Runlight remains lit, but the Pumpingindicator stops. The pump does not givean occlusion alarm immediately, butonly alarms if the occlusion pressurecontinues to exceed the occlusionthreshold for 10 seconds. This helps toavoid nuisance occlusions.

However, the pump monitors anytemporary occlusions, and if suchocclusions persist, then the occlusionalarm is generated.

If an occlusion is detected when theocclusion alarm is set to Low, the pumpalarms immediately.

I f an occ lus ion is detectedIf an occlusion alarm occursIf an occlusion alarm occurs,immediately clamp the line to thepatient. Then inspect the fluid pathwayto determine what has caused theobstruction.



You can check the current occlusionalarm setting when an infusion isrunning if you press the OcclusionAlarm Setting key. You can change thesetting if you first put the infusion onHold, see steps in opposite column.

When you switch the pump on, theOcclusion Alarm setting is always thesame, and is defined by the TechnicianMenu configuration setting. You shouldset the alarm to be appropriate for theinfusion before pressing Run.

The occlusion alarm setting determinesthe amount of back pressure allowedbefore the pump alarms. There arethree possible settings: Low, Mediumor High.

Whilst the pump is infusing,particularly at higher infusion rates, orwith thick solutions (see Noteopposite), or with small diametercannulas, you may see the followingalarm message:

If there is no obvious reason for thealarm, the message may occur becauseyou have not selected an appropriateOcclusion Alarm Setting for theinfusion. If this is the case, you maywant to change the Occlusion AlarmSetting.

To change the Occlusion Alarm Settingduring an infusion, whether or not analarm has occurred:

1. Press Hold to silence the alarm ifnecessary, and stop the infusion.

2. Press the Occlusion AlarmSetting key once to display thecurrent setting.

3. Press the Occlusion AlarmSetting key repeatedly to displaythe available settings.

4. When the correct setting isdisplayed, press Run.

Change the Occlusion alarm sett ing

WARNING: If using a blood pressure cuffabove the patient’s venipuncture site takeextra care in setting the Occlusion alarmpressures. Failure to do so may result inunnecessary Occlusion alarms, resulting inpatient injury or death.

WARNING: The Occlusion detectionsystem measures downline back pressurein the administration set, but does notdetect infiltration. In accordance withlocal protocol, you must periodicallyinspect the patient’s infusion site forsigns of infiltration. Failure to do so mayresult in an unacceptably slow time toOcclusion resulting in patient injury ordeath.

Approximate Occlusion alarm settingsLow 2 psi, 103 mmHg, 13.5 kPa

Medium 5 psi, 259 mmHg, 34.5 kPa

High 10 psi, 517 mmHg, 68.9 kPa

When an occlusion alarm occurs, thepumping mechanism backs off toreduce down-line pressure and boluspotential (bolus potential isapproximately 0.3 mL regardless ofthe rate and the administration setused).

Note: A thick solution may be certaincytotoxic agents, lipid-based fluidsand other viscous solutions, forexample Total Parenteral Nutrition.

The pump warns you that the infusionis complete when the Primary Volumeto be Infused reaches zero.

At this moment, the pump sounds atwo-tone alarm. You can decide to:

Ending the Pr imary in fus ion

KVO infus ionIf you press Silence to stop the alarm,the pump continues to infuse at theKVO (Keep Vein Open) rate. The KVOrate is shown on the Rate display.

Depending on how the pump isconfigured, the KVO rate may be:

• the default KVO rate of 3.0 mL/h,• the programmed infusion rate if

that was less than 3.0 mL/h;• the KVO rate specified for this

pump, see Specifying a different KVORate, below.

The Message Display shows “KVO”, aswell as the combined Primary and KVOvolume infused, for example:

The pump continues to infuse at theKVO rate. After six minutes, the twotone alarm sounds again, as a reminderthat the KVO infusion is still running.You can decide to:

• silence the alarm and stop theinfusion - press the Hold key

• silence the alarm and continue toinfuse at the KVO Rate - press theSilence key.

Specifying a different KVO rate

If the ‘KVO Rate Entry’ option has beenenabled in the Technician Menu, you canuse the Options key to specify a KVOrate, before you start the infusion.When you set the KVO rate you can goto a maximum of 10 mL/h (on a 500pump) or 3mL/h (on a 505 pump) or theMax Primary Rate if one is also enabledand set below these limits.If the programmed infusion rate is lessthan the set KVO rate, when the pumpgoes into KVO, it will continue pumpingat the programmed lower rate.For full details on how to set the KVOrate, see Chapter 3, Options.

• silence the alarm and stop theinfusion - press the Hold key

• silence the alarm and continue toinfuse at the KVO Rate - press theSilence key (see details below).



About Secondary infusionsThe pump has the facility for you to setup and run a Secondary infusion, forexample, to:

• administer a dose of antibiotics to apatient who is already receiving aPrimary infusion;

• administer a loading dose of a drug,of a different concentration of thesame drug as in the Primarycontainer.

You use the Secondary/Bolus key toprogram a Secondary infusion. TheSecondary volume infused is kept as aseparate total. It is not deducted fromthe Primary Volume to be Infused.

Once you have started an infusion fromthe Secondary set, the solution from theSecondary container takes precedenceover the Primary infusion. For details

on what happens if the Volume to beInfused is less than the contents of theSecondary container, see page 2-27.

Secondary Rate and VTBI limits maybe set if enabled in the Technicianmenu. See page 2-15 for more details.

Bolus feature enabledIf the Bolus feature has been enabled inthe Technician Menu, you can use theSecondary/Bolus key to:

• run a Secondary infusion, wherethe volume infused is not deductedfrom the Primary Volume to beInfused;

or alternatively,• run a Bolus infusion, where the

volume infused is deducted fromthe Primary Volume to be Infused.

Sett ing up a Secondary infusion

To set up a Secondary infusion, youneed a means of combining a Primaryand Secondary infusion. This may bethe combined Primary/Secondary (8C-6200) IV Administration set fromGraseby Medical, product code 591.096.

Alternatively, use an administration setwith an injection site or Y-site (asshown here) plus a SecondaryAdministration set (not shown).

The basic steps for setting up aSecondary infusion are described in thefollowing sections:

• lower the Primary solution container;• prime the Secondary administration

set;• connect the Secondary to the

Primary administration set;• program the Secondary infusion

(with or without the Bolus featureenabled);

• start the infusion.



2 — 2 7


You must always follow the Instructionsfor Use that accompany the particularadministration set to be primed. Eachset contains specific priminginstructions, and also gives details ofany warnings concerning the use of theadministration set.

Pr ime the Secondary admin is t ra t ion set

Open the packaging around theSecondary administration set and findthe hanger that looks something likethis:

Take the Primary container from the IVpole and use the hanger to suspend itfrom the IV pole.

Lower the Pr imary solut ion conta inerThis should lower the Primarycontainer by approximately 20 cm(eight inches). Make sure that the dripchamber on the Primary container isstill at least 15 cm (six inches) abovethe pump.

WARNING: Do not run parallel infusionlines below the pump. Delivering aSecondary infusion means running asecond line above the pump. Failure to doso may result in an inaccurate delivery ofmedication, resulting in patient injury ordeath.



Connect the Secondary to the Pr imaryadmin is t ra t ion se tIf you are using the combined Primary/Secondary (8C-6200) IVAdministration set from GrasebyMedical, product code 591.096, followits accompanying Instructions for Use.

If you are using a separate Primary andSecondary set, then go through thefollowing steps.

1. Insert the needle from the Secondaryset into the injection site on thePrimary set.

2. Keep the Secondary clamps closeduntil you are ready to start theSecondary infusion.

3. Check that the roller clamp belowthe pump is closed, and go on toprogram the Secondary infusion.

The position of the two solutioncontainers and administration sets isshown on the diagram on page 2-13.

WARNING: Check the Secondary setcarefully, since an occlusion above thepump on the Secondary line could causethe Primary fluid to be delivered instead ofthe Secondary infusion. Administering thewrong medication may cause seriouspatient injury or death.

About the Secondary Volume to be In fusedBecause the Secondary container hangson the IV pole at a higher level than thePrimary, the entire contents of theSecondary container may be infused atthe end of the Secondary infusion. Thiscan happen even though the SecondaryVolume to be Infused is zero.

On a pump where Secondary Stop is notenabled in the Technician Menu, youmust ensure that the amount that youenter as the Secondary Volume to beInfused is equal to the volume of fluidin the Secondary container.

If the Secondary Stop feature isenabled, the pump stops infusing andsounds an alarm when the Secondaryinfusion is complete and the SecondaryVolume to be Infused has beendelivered. You can then clamp theSecondary set to prevent any more fluidfrom being infused from the Secondarycontainer.

WARNING: The Secondary volume to beinfused must match the amount of fluid inthe Secondary container. Primary flowresumes when the Secondary container isempty. If the volumes do not correspond,the wrong infusion may be deliveredwhich could cause serious patient injury ordeath.

6. Rate TaperThis option, if enabled, allowsautomatic tapering of the infusion rate,either up or down for theadministration of Total ParenteralNutrition (TPN).

Rate taper is programmed by settingfour infusion variables.

1. Volume

2. Total time or Maximum rate

3. Taper up time

4. Taper down time

The pump then makes the necessarycalculations and performs the ratechanges at the required times.

A Rate Taper infusion can be repeatedexactly as the previous infusion, orchanges can be made if the volume ortime requirements vary from oneinfusion to another.

This option cannot be used while theQuick Rate Change, Volume Over Timesetup, or Dose-Rate Calculation is inuse.

If the pump is switched off whilst inRate taper mode, and not connected tothe AC mains supply when it isswitched on again, the automaticbattery test is carried out, but theBattery Gauge is not displayed. If thebattery is low, the alarm sounds and awarning message is displayed.

Resuming, restart ing or reprogramming theRate Taper

Any limits set with options (such asRate or VTBI limits) will apply. Youwill be able to program Rate Taperas normal, but you will be preventedfrom running the infusion. For moredetails, see page 3-16.



Programming or reprogramming the Rate Taperwith Limits setIf any limits are set for the PrimaryRate or Max VTBI, then these willapply when you program the RateTaper or if you modify a program.Setting limits is described on page3-29.

Before you enter Rate TaperIt is worthwhile checking what valuesare set for Min and Max Primary Ratelimits and for Max VTBI before youenter Rate Taper. If they areinappropriate for the prescription, youcan then adjust them and not have theRate Taper infusion halt as describedbelow.

If you program outside the limitsThe pump tests whether the entered orcalculated values are within the limitswhen you press Run. This also appliesif you change values as described on theprevious page.

If the pump detects that the calculatedrate is outside the limits, or the VTBIis too high, then the alarm sounds andthe Message Display shows thiswarning:

Note: This happens when thecalculated rate is valid, but notacceptable because of the VTBI orinfusion rate limits set on the pump. Itis not the same as the “cannot infuse”message displayed because the ratecalculation is invalid.

To silence alarm and leave Rate TaperIf you see the Preset Limits messagewhen you are programming orreprogramming a Rate Taper infusion,

• Press the Silence key to silence thealarm. The pump automaticallyleaves Rate Taper and displays theStandard Message:

This is so that you can use the Optionskey to check and if appropriate, adjustthe preset limits, which you cannot dowhen you are in Rate Taper.

Troubleshooting Preset Limits error inRate Taper programTo find out why the Rate Taperprogram exceeds the limits, check thefollowing:

1. Check the prescription volumeagainst the Maximum VTBI limitand adjust the limit if it isincompatible with the prescription.

2. If the prescription requires that youenter a Maximum Rate, check thisagainst the Max Rate limit setting.

3. If the VTBI or Rate limits areacceptable, note all limits that areset by using the Options key. Re-enter Rate Taper and check if youhave made a mistake inprogramming the prescription.

4. Step through the program, look atthe calculated values and comparethem to the limits.

Dose or rate change alarms



Programming or reprogramming Dose-RateCalculat ion with Limits setIf any Limits are set for the PrimaryRate or Max VTBI, then these willapply when you program the Dose-RateCalculation or if you modify a program.Setting limits is described on page 3-29.

Before you enter Dose-RateCalculationIt is worthwhile checking what valuesare set for Min and Max Primary Ratelimits and for Max VTBI before youenter Dose-Rate Calculation. If theyare inappropriate for the prescription,you can adjust them and not have theinfusion halt as described below.

If you program outside the limitsThe pump tests whether the entered orcalculated values are within the limitswhen you press Run.

If the pump detects that the calculatedrate is outside the limits, or the VTBIis too high, then the alarm sounds andthe Message Display shows:

Note: This happens when the cal-culated rate is valid, but is outside theVTBI or infusion rate limits set on thepump. It is not the same as the “cannotinfuse” message displayed if thecalculation is invalid.

To silence alarm and leave DRCIf you see the Preset Limits messagewhen you are programming orreprogramming a Dose-RateCalculation infusion, Press the Silencekey to silence the alarm. The pumpautomatically leaves Dose-Rate

Calculation and displays the StandardMessage:

This is so that you can use the Optionskey to check and if appropriate, adjustthe preset limits, which you cannot dowhen you are in Dose-Rate Calculation.

Troubleshooting Limits in a DRC programTo find out why the Dose-RateCalculation program exceeds thelimits, check the following:

1. Check the prescription volume (thevolume in the bag) against the VTBIlimit and adjust the limit if it isincompatible with the prescription.

2. The rate calculated will remain inthe LED display when you are takenout of Dose-Rate Calculation. Checkthis against the Rate limit setting.

3. Check the value for the VTBI sinceyou may have accepted all values fora previous Dose-Rate calculationprogram and this will not haveupdated the VTBI from the bagvolume.

4. If the VTBI or Rate limits areacceptable, note all limits that areset by using the Options key. Re-enter Dose-Rate Calculation andcheck if you have made a mistake inprogramming the prescription.

If you change the rate while runningIf you change the rate (either the dosingrate or the pump infusion rate) whilerunning, and exceed the limits, thenpress Run, the pump alarms butcontinues at the programmed rate.

O p t i o n s

Sett ing Rate and VTBI l imitsYou can limit the infusion Rates andVTBI (volume to be infused) values foreach pump. When you set up aninfusion, the pump rejects a Rate orVTBI value that is not within theMinimum/Maximum rate limits, or isgreater than the maximum VTBI.

For example, you should set amaximum rate on a pump that isintended for use in an Epiduralapplication, or set a maximum VTBI ona pump to be used in a neonatalenvironment. Setting rate limits is alsocalled Rate Capping.

Rate Taper, Volume Over Time andDose-Rate Calculation are also affectedby limit settings.

The following Options are used to limitthe infusion rates and volumes to beinfused on the pump:

Minimum and Maximum Infusion Rates

For Primary infusions:

• Min Rate, Max Rate, Max VTBI.

For Secondary or Bolus infusions:

• Min S/B Rate, Max S/B Rate,Max S/B VTBI.

To define the ranges, the items must beenabled on the Technician Menu, andthen set using the Options key.

See page 3-32 for more details on howlimits affect programming an infusion.

If the Primary ‘Min Rate’ and ‘MaxRate’ are enabled in the TechnicianMenu, their current settings aredisplayed when you switch on the pump.If the defaults have not been changed(on a Model 500), the screen looks likethis:

The Secondary/Bolus Maximum andMinimum rates are not displayed whenyou switch on the pump, even if they areenabled and set.

Entering ratesRates must be entered as wholenumbers: they cannot include a decimalpoint. If the Min Rate is set to zero,there is no lower limit. The Max Ratemay be set to 999 (on a Model 500) or99 (on a Micro 505).

The instructions on the followingpages explain how to set values forthe (Primary) Minimum andMaximum Rate and MaximumVTBI. Once you have understoodhow to change these values, youwill find that you can set theSecondary/Bolus minimum andmaximum rates in the same way.

Unless the display includes S/B,the rate being changed is alwaysthe Primary.



1. Press the Options key repeatedlyuntil you see the Minimum Ratedisplay. The current minimuminfusion rate flashes, showing thatyou can change this value.

2. Enter a new rate, using the numerickeypad, then press the * key toconfirm.If it is correct, to leave the rateunchanged, just press *.If the pump finds that the rate isinvalid, the number continues toflash, so you should repeat this step.

3. With the value for Min Rate static,press the Options key to displaythe flashing Maximum Primaryrate.

4. Enter a new rate then press * to setthe value. Just press * if you want toleave the maximum rate unchanged.

You can now do one of the following:

• press the Options key once to moveon to the next Option;

• press the Options key repeatedly tomove through all the Options thathave been enabled on the pump. Youcan stop when the StandardMessage is displayed on the screen,indicating that the pump is ready tobe programmed, or carry on until youreach the Min Rate screen again,where you can make further changes;

• turn the pump off then on again, tosee the new primary minimum andmaximum values in the messagesdisplayed in the power up sequence.

To set the minimum and maximum infusion rateIf the Options are enabled, you canchange either or both values. This sectionexplains how to change both values.

2. Enter a new VTBI, using thenumeric keypad, then press the *key to confirm.If it is correct, to leave the VTBIunchanged, just press *.If the pump finds that the rate isinvalid, the number continues toflash, so you should repeat thisstep.

3. Press the Options key to take youto the next option.

To set the maximum infusion volume

This Option is to limit the volume thatmay be programmed for a singleinfusion. The Max VTBI is 9999 (on aModel 500) or 999 (on a Micro 505),There is no lower limit for the VTBI.

If the Primary Maximum VTBI isenabled, the current setting isdisplayed when you switch on thepump.

If the default has not been changed, (ona Model 500) the screen looks like this:

Maximum VTBIThe Max Secondary/Bolus VTBI is notdisplayed, even if it is enabled.

The example here shows how to setthe Maximum VTBI for the Primaryinfusion. The process is the same forsetting the Maximum VTBI for theSecondary/Bolus infusion.



Programming and running infusions with l imits

If limits are set and you try to run aninfusion, the pump will prevent youfrom running with a rate or VTBI valueentered outside the limits. Thisincludes special infusion modes such asVolume over Time, Rate Taper andDose-Rate calculation. In the latter twoinfusion modes, the pump behaves in aslightly different way.

For Rate Taper, instructions onprogramming with limits set aredescribed on page 3-16.

For Dose-Rate Calculation,instructions on programming withlimits set are described on page 3-28.

If you change rates while running or putthe pump on hold and change thevolume, the limits are checked whenyou press Run. The pump continues toinfuse at the previous rate when anerror is detected during a rate changewhile running.

Rate limit settings also affect QuickRate changes.

When the pump detects a value whichis outside the set limits it sounds analarm and the Message Display shows:

Silence the alarm and enter a valuewhich is valid for the limits. Theprevious value is restored to the LEDdisplay.

If are using Quick Rate change, and tryto move outside the rate limits, thepump will alarm with the limitsexceeded message, and the rate LEDwill show the limit setting. If you arechanging the rate while the pump isrunning, the infusion will continue atthe limit rate.

KVO rateThe pump automatically switches to aKVO infusion when the programmedinfusion ends. The default rate for KVOis 3.0 mL/h, or the programmedinfusion rate if that was less than 3.0mL/h.

The KVO option, if enabled in theTechnician Menu, allows you to set adifferent KVO rate.

The pump remembers the value enteredas described here, and uses it as theKVO rate. You cannot set the KVO rateto zero.

The range for the KVO rate must bewithin the following limits:

500 0.1 to 10.0 mL/hMicro 505 0.1 to 3.0 mL/h.

1. Press the Options key until you seethe KVO rate display. The currentvalue flashes, showing that you canenter a new value.

2. Enter the new KVO Rate using thenumeric keypad, then press * toconfirm.If the rate is correct, press Optionsto move on to the next Option.

In the unusual situation that the rateyou enter is not accepted, then the MaxPrimary Rate limits are set below thevalue you wish to enter. The MinPrimary Rate does not affect the KVOentry.

Sett ing a KVO rate

When you set the KVO rate, if the MaxPrimary Rate is also enabled and setbelow these limits, then that will definethe maximum KVO value you can enter.If the programmed infusion rate is lessthan the set KVO rate, when the pumpgoes into KVO, it will continue pumpingat the programmed lower rate.KVO rates cannot be changed when aninfusion is running, but if you press theOptions key, the current setting isdisplayed.



Drug LabelThe Drug List feature, if enabled in theTechnician Menu, allows you to use theOptions key to select a drug label froma predefined list that is stored in thepump.

When the Drug List is enabled, theselected drug label is displayed for twoseconds when you switch on the pump,for example:

Drug Library

If no drug label has been selected, thescreen is shown like this:

The selected Drug Label is displayedfor two seconds if you press * when thepump is on hold, or infusing.

If you press the Options key when aninfusion is running, you will also seethe current label, but will not be able tochange it.

This is a complete alphabetical list ofthe drug labels retained in the pump’smemory. Due to the number ofcharacters that the pump can displaysome of the drug names have beenshortened or abbreviated.

T r o u b l e s h o o t i n g

The chapter contains two sections:

• warning messages with alarms,divided into Continuous (backup)alarm, Insistent alarms and Non-insistent alarms;

• warning messages with no alarms.

The chapter lists the possible causesand recommended action to take foreach of the warning messages.

What ’s in th is chapter

In t roduct ionThis chapter covers all the errormessages and alarms, displayed by theVolumetric, that notify you of anyoperating problem.

If you cannot solve the problem afterreading this chapter, the pump shouldbe inspected and repaired by a suitablyqualified technician, or returned toGraseby Medical at the address on theback cover of this Instruction Manual,in order to have the fault rectified.

The chapter does not contain details ofthe Volumetric pump System errors orwarnings that indicate a problem thatcan only be solved by the Biomedicalengineering department, or by returningto the distributor/factory. These aredescribed in the Volumetric ServiceManual.

You should read this chapter to find outhow to solve any problems that arisewhilst you are using the Volumetricpump.

You are likely to be in one of thefollowing groups:

• Biomedical engineeringdepartment, needing to find outwhat alarms may arise during thenormal operation of the pump

Who should read this chapter• People being trained, who have

access to the Instruction Manual asadditional training material

• People who have been trained, whoneed a concise summary to remindthem of the Volumetric pump’salarms and a description of what todo if the pump sounds an alarm.


T r o u b l e s h o o t i n g G r a s e b y M e d i c a l L t d .

CAUTION: Refer all service repair andcalibrations only to qualified technicalpersonnel. Unauthorised modifications tothe pump must not be carried out.

WARNING: You should ensure that theperformance offered by the pump is fit forthe intended purpose. Failure to do somay result in compromised function ofthe product, patient injury or user injury.

WARNING: Do not use a faulty pump. Ifthe pump detects a fault when it is firstturned on, or if it develops a fault duringoperation then a continuous system alarmsounds. The pump must be referred to asuitably qualified technician or returnedto Graseby Medical in order to have thefault rectified.

Handl ing problems with the pumpMost problems in using the pump aresignalled by alarms whoseaccompanying messages are describedin the rest of this manual.

You should also use your experience inusing the pump to take action if thepump behaves as if it is faulty. Followthe warnings and cautions on this pageto take appropriate action to send thepump to a suitably qualified technicianfor checking.

Pump wil l not switch onIf the pump does not switch on whenthe On/Off key is pressed whenconnected to an AC power supply.Check that the keypad lockout featureis not active, see Safety keypad lockout,page 2-22.

WARNING: Before using the pump, itshould be inspected for physical damage.The pump should not be used if damageis evident, and should be returned toservice personnel for repair before beingreturned to use. Failure to do so mayresult in compromised function of theproduct, patient injury or user injury.

WARNING: Do not open the pumphousing. Refer all service faults only toqualified technical personnel. Openingthe pump housing may cause electricshock leading to patient or user injury ordeath.

Nurse-Cal l FeatureSome pumps are fitted with a Nurse-Call feature which makes these pumpscompatible with most existing hospitalnurse-call systems.

A Graseby Medical pump equippedwith the nurse-call feature may beconnected to the hospital's system byinserting a 0.25 inch system plug into

the Nurse-Call Connector (seeillustration, below) on the pump's rearpanel.

Once connected, any activation of thepump's various audio alarms alsoactivates the hospital nurse-callsystem.
