During assembly, the support member (20) is firstly fitted to the bag with the projection (26) projecting through the aperture (34), and the valve member (22) is then fitted to the projection (26). In an alternative form, the support has two hook-shaped projections on either side of the outlet tube (16) to which a modified valve member is clipped.

Abstract: The specification describes several uses for pressure sensitive valves during extracorporeal pumping in one embodiment, an improved pumping loop for a roller pump is used in an extracorporeal circuit with a pressure relief valve and pump tubing. The inlet and outlet of the tubing are connected respectively to the outlet and inlet of said valve via two 3 way connections, across the outlet of the pump. The pumping loop allows recirculation of pumped liquid between the inlet and outlet of the pump when the outlet pressure generated by said pump exceeds a set value thereby limiting the pump outlet pressure to the set pressure. The pressure relief valve can also be placed at the inlet if the pump to protect the circuit from excess negative pressure that the pump can generate. The pressure relief valve in combination with the pump loop provides an accurate means to dynamically set the occlusion of the tubing within the roller pump.

Abstract: A tongue and groove construction maintains the catch and latch part of a tube clamp in full registration with one another across its entire range of positions from fully open to fully closed. A groove bisects the teeth of the latch member and a complementally formed tongue bisects the catch member of the clamp. Thus, when the tongue is slidably received within the groove, the parts of the catch member that flank the tongue releasably engage the parts of the latch member that flank the groove. This maintains the tube pinching elements in full alignment with one another so that when the pinching elements are fully displaced toward one another, no liquid fluid may flow through a cannula disposed therebetween. The teeth are not provided in a second embodiment, but the tongue and groove arrangement is employed in that embodiment. The tongue engages the underside of a lip, and the clamp is either fully open or fully closed.

Abstract: A fluid control valve which has a deformable valve member with a fluid passageway therethrough. The fluid passageway is closed by a pressure-exerting member.

Abstract: Mounted adjacent the end of a plastic hose remote from its connection to a kitchen sink faucet or other such water source is an improved hose-pinching clamp assembly of the present invention which enables effective watering of remotely located plants. The significant improvement in performance is that the clamp, during normal watering service, is confined to providing a desirable "soft" stream by a pliable sleeve or tube in covering relation over the clamp, said tube maintaining the clamp partially closed upon the hose so as to restrict flow to said "soft" stream. Prior art clamps, in contrast, can inadvertently be opened too much, and may therefore operate with a watering stream that splashes or otherwise is unsuitable for the purposes intended.
