Abstract
In accordance with the present invention, a safety monitoring apparatus provides protection in the event of an alarm condition or failure in a patient care system. More particularly, the safety monitoring apparatus is an independent functional unit within a device such as an infusion pump unit which provides single-fault protection in the event of an alarm condition or failure in the pump itself or in the primary control and monitoring means of the pump. The safety monitor utilizes control and signal inputs and can detect fault conditions independently of the primary control and monitoring means of the pump. Parameters which the safety monitoring apparatus may independently monitor in an infusion pump include motor control, air-in-line, flow-stop detection, mechanism motion, pressure sensing, door position sensing, and total volume infused. If a fault condition is sensed, the safety monitor can notify the primary control means, independently shut down fluid delivery, or sequentially do both.
