DISPOSABLE FLUID INFUSION PUMPING CHAMBER CASSETTE HAVING A PUSH BUTTON FLOW STOP THEREON

摘要

A simple disposable infusion pumping cassette is provided for use with a drug infusion pump. The cassette includes internal means for mounting an elastomeric member (16) between a face member (12) and a base member (14) and in fluid-tight engagement within the cassette. The cassette includes a pumping chamber (22) and a proximal (56) and a distal pressure monitoring chamber (57) adjacent thereto. A flow stop (24) mounted on the cassette is operative to prevent fluid flow through the cassette in a first mode and to monitor fluid pressure in the cassette in a second mode.
