ABSTRACT:
A disposable pinch valve assembly for parenteral solution delivery systems comprises a two-piece tubing receptor housing hingedly connected and with an irreversible snap connection which will not permit removal of the device from parenteral tubing after assembly. A back section has an integral movable pressure plate attached to the housing by integral flexible web connectors. When the movable plate is actuated toward the stationary press surface, tubing is pinched therebetween and the cross-section area of the flow passage through the tubing is reduced. The movable pressure plate is designed to engage a actuator connector which engages the device with a motor-driven actuator in an axially sliding engagement.
