ABSTRACT:
A system for detecting an occlusion in a fluid line is disclosed which can detect occlusions in the downstream or patient side of a disposable cassette containing a fluid pump thereon. The cassette includes a pressure diaphragm and is for installation onto and use with a main pump unit including a pressure transducer therein for monitoring fluid pressure downstream of the pump. The system utilizes control circuitry to provide an alarm in the event of a patient-side occlusion, and the occlusion detection system works when the system is configured as any of a number of difference device types, including both a flow controller emulation and several different infusion pump configurations.
