Power system for infusion pumps

Abstract

Abstract A safety system for battery-operated, microprocessor-­ controlled infusion pumps using separate primary and reserve batteries. When the primary battery nears exhaus­ tion, 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 person­ nel of the various phases in the system's operation.
