Abstract

An intravenous and intra arterial delivery system is described having a disposable cassette actuated by a pump and control electronics for providing positive but variable delivery rates. The cassette is self-priming and provides protection against the delivery of air by being unable to impel air, and means provide an indication of excessive air in the cassette. The electronics has low power consumption so as to be suitable for battery operation, such as by way of rechargeable batteries. A pressure sensor in the delivery line may be used to sense infiltration. The system further features a provision for predetermining the amount of fluid to be delivered, and a detection system for detecting an empty supply bottle.
