<p>A method for the transfer of body fluid which accumulates in the peritoneal cavity into the vascular system is disclosed. This accumulation occurs most frequently with patients suffering from cirrhosis of the liver and constitutes a lethal complication. An implant device is disclosed which comprises a plastic chamber and connecting tubing, said chamber containing unique valve structure comprising a flexible diaphragm seated on a shoulder and attached to this diaphragm a connector bar which is attached at its other end to the center plate of a structure composed of several lateral silicone rubber struts which radiate out from the center plate to connect to a circular peripheral ring. The circular peripheral ring is anchored fixedly to the lateral wall of the valve housing by compression between two threaded connectors of plastic also. These rubber struts place pressure constantly on the diaphragm pulling it toward the shoulder which closes the valve. The diaphragm member is thus fixed to the side wall of the valve housing by the elastomeric strut members. The seat of the diaphragm valve is adjustable and hence it can control the fluid pressure required to open the valve.</p> |
