Urination, Micturition, Voiding Process of disposing

urine from the urinary bladder through the urethra to the outside of the body

Process is under voluntary control

Main organs involvedUrinary bladderUrethra

Urinary Bladder and Urethra Detrusor muscles

Smooth muscles of the bladder Innervated by sympathetic and

parasympathetic nerves Internal urethral sphincter

Located at the proximal inferior end of the bladder, at the junction of the urethra with the bladder

Smooth muscle Under involuntary control

External urethral sphincter Located at the distal inferior end of the

bladder Skeletal muscle Under voluntary control

To void Detrusor muscles contract Relaxation of the sphincters Voluntary contraction of the abdominal

muscles

What is Urinary Incontinence? Urge Incontinence

Involuntary loss of urine associated with abrupt and strong desire to void

Stress Incontinence Involuntary loss of urine during coughing,

sneezing, laughing, etc

Overflow Incontinence Involuntary loss of urine associated with

over distension of bladder

Functional Incontinence No recognition of need to void, inability

to make it to the toilet in time

Causes Neurological disorders

Parkinson’s, Multiple Sclerosis, Alzheimer‘sStroke, brain tumor, spinal injury

Hormone imbalancesMenopause

Prostate cancer Loss of muscle tone

Childbirth, old age

Prevalence 13 million people in the U.S. 10-35% of adults 50% of the 1.5 million

residents in nursing homes leading cause of admission to

a nursing home may lead to pressure sores

and ulcers, possibly resulting in secondary infections

Specifications Desired Comply with industry standards for

urological medical devices Be able to remain indwelling for 30 days Easily operated by patient with disabilities Allow emptying of the bladder when

desired Prevent urine flow when not desired Provide an indication of the status of the

bladder.

AMS 800

artificial urinary sphincter

implantable, fluid-filled, solid silicone elastomer

AMS 800 Testing Determined the force required to compress

the pump of the AMS 800 6.3 mm was too much for the electromagnets.

Decided to create a new design based off the AMS 800 using electromagnets.

Interstim Typically used to treat

urge incontinence Inserted into the sacral

nerves to activate or inhibit muscles and organs that contribute to urinary control -- the bladder, sphincter and pelvic floor muscles.

Cost of device: $8,800.00

We are using it as a power source

Design A Electromagnets will be

activated causing the device to clamp the urethra closed.

Second set of electromagnets will release the clamp.

Design B Utilize a servo and

push rod to collapse urethra

Powered by 4.8V

Provides sufficient torque to drive a sphincter mechanism

Methods Adapt an actuator to activate

the device

Actuator will receive a signal through a micro RC receiver

RC receiver is controlled externally to allow simple evacuation of bladder

Dimensions : .85 x 1.25 x .5“

Status Corresponding with Konica Minolta ,

Systemax and Hitachi about circuitry for our device
