<p>A disposable pinch valve assembly for parental solution delivery systems comprises atwo-piecetubing receptorhous- ing with a front section (2) and back section (4) joined by a hinge (6) and with an irreversible snap connection (20, 22, 24, 26) which prevents removal of the device from parenteral tubing after assembly. The back section (4) has a movable pressure plate (16) and the front section (2) has a stationary pressure plate (28), sothattubing betweenthe pressure plates may be pinched therebetween in response to axial displacement of the movable pressure plate (16) by a motor driven actuator.</p> |
