ABSTRACT:
A disposable crimping 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 bent over a sharp ridge element until the wall thereof contacting the sharp ridge collapses in a crimping action. The motor drive assembly provides rotational pressure to a threaded actuator engaging the back section without applying axial pressure thereto. The clamp permits manual adjustment to set flow rates when it is separated from the control housing.
