Cyclic total parenteral nutrition is safely administered by tapering the infusion rate over a substantial period of time at the beginning and end of the infusion cycle. An infusion pump is disclosed which automatically calculates and performs a cycle profile having an appropriate steady-state rate and appropriate tapers in accordance with pre-established criteria when total volume and total infusion time per cycle are entered. The pump has a sleep mode for energy conservation without loss of memory when predetermined periods of inactivity occur.

Method and apparatus for automatic profiled infusion in cyclic TPN

A plurality of infusion pump modules are detachably connected to a portable central management unit. The modules can be programmed by the central management unit, and their operating information displayed by the central management unit, when they are connected to it; yet the modules, once programmed, can operate independently when detached from the central mangagement unit, and they can display limited operational information on their own.

Centrally managed modular infusion pump system

A safety system for battery-operated, microprocessor-controlled infusion pumps using separate primary and reserve batteries. When the primary battery nears exhaustion, the reserve battery is switched in and an interval timer is started, but the pump operation is not interfered with. At the expiration of the timer interval, the pump is switched to a KVO mode to keep it in minimal operation as long as possible. When the reserve battery also nears exhaustion, the microprocessor is signalled to perform an orderly shutdown routine while battery power is still available. Audible alarms may be provided to apprise nursing personnel of the various phases in the system's operation.

Power system for infusion pumps

The present invention is a sensing amplifier circuit for a tissue stimulator (72) for supplying or attenuating far field signal voltage artifacts comprising a full differential amplifier having a first (94, 136) and second (96, 142) stage amplifiers for respectively receiving a second and first signal voltage output from a sensing mean (80, 82), and a switch means for controlling an input of the second signal voltage output from said sensing means to the first stage amplifier (94, 136).
