29 Recognition tag in finger grip of ‘Diprivan’ PFS Important safety features Correct drug identification and usage l Operates in ‘Diprifusor’ TCI mode only with tagged ‘Diprivan’ PFS – no other drugs l Confirms ‘Diprivan’ concentration (1% or 2%) for correct infusion at requested target concentration l Erases tag when PFS is nearly empty and prevents refilling/reuse The recognition tag* (“electronic marker”) in the finger grip of a ‘Diprivan’ PFS provides important safety features for correct drug identification and usage. The tag is an encoded capsule that is visible on one side of the finger grip. To load a ‘Diprivan’ PFS into a syringe pump that incorporates ‘Diprifusor’, the tagged side of the finger grip is inserted into the “ear groove” and rotated. The display advises when the PFS has been loaded correctly. Magnetic resonance “signals” are generated by the tag. An aerial in the syringe pump detects these signals and relays them to the ‘Diprifusor’ TCI Subsystem. The electronics and software in the ‘Diprifusor’ TCI Subsystem “read” these “signals” and ensure that: • The syringe pump will only operate in ‘Diprifusor’ TCI mode with a tagged ‘Diprivan’ PFS • The ‘Diprifusor’ TCI Software recognises whether a 1% or 2% ‘Diprivan’ PFS has been loaded. There are two consequences for safe operation: • ‘Diprivan’ is the only drug that is infused when the syringe pump is in ‘Diprifusor’ TCI mode • The automatic confirmation of concentration means that the correct infusion pattern — and target concentration — is obtained irrespective of whether a 1% or 2% ‘Diprivan’ PFS is loaded. A third feature enhances patient safety relating to aseptic precautions. When the contents of a ‘Diprivan’ PFS have been infused, the recognition tag is erased. This helps prevent any refilling and reuse of that syringe in TCI mode whether in the same or another patient. The user can, of course, load another tagged ‘Diprivan’ PFS. (The syringe pump displays instructions about loading a new ‘Diprivan’ PFS and ‘Diprifusor’ provides automatic compensation for the short interruption.) *Programmable Magnetic Resonance (PMR) tag in the finger grip of a ‘Diprivan’ Pre-Filled Syringe: this technology is licensed from Scientific Generics Limited.
