A device for the transfer of body fluids which accumulate in the peritoneum cavity into the vascular system comprising a peritoneal tube connected to the inlet chamber of a hollow plastic implanted valve assembly, causing a valve to open and passing the fluid under pressure into a second chamber from where the fluid is conducted through a venous tubing which is connected to the jugular vein of the patient. The valve assembly comprises a plastic housing with an inlet and outlet, the peritoneal tube being secured to the inlet leading to an inlet reservoir located within the valve housing and the venous tube being secured to the outlet leading from the outlet reservoir located within the valve housing. The valve housing defining a valve seat and having a flexible diaphragm valve which rests against the valve seat and moves away from said valve seat in response to pressure exerted thereon to permit flow of the body fluid from the peritoneum through the valve housing and into the venous tubing which is threaded into a major intrathoracic vein via the internal jugular vein or other alternate access veins.

[ What we claim is:] [1.] A shunt assembly for the transfer of body fluids which accumulate in a peritoneum cavity of a patient into a vascular system of the patient comprising a peritoneal tube connected to an inlet valve chamber of a plastic valve means with one end being positioned in the peritoneum, so that pressurized fluid transported from the peritoneum cavity will cause the valve means to open and pass the fluid under pressure into an outlet valve chamber and through a venous tubing which is connected thereto and into an access vein in a thorax of the patient, said valve means comprising a thin rigid transparent plastic housing defining two separated chambers, one chamber being provided with inlet port means comprising an opened faced conduit and the other chamber being provided with exit port means comprising an opened faced conduit, top and bottom covers removably secured to said housing allowing access to respective chambers when removed from said housing, a moveable valve seated in said housing adapted to move allowing fluid to flow from said inlet port housing chamber, past said valve and into said outlet port housing chamber said moveable valve member comprising a flexible conical shaped diaphragm means which rests against a valve seat formed in said housing between said outlet valve chamber and said inlet valve chamber, said valve diaphragm means moving away from said valve seat in response to a differential pressure exerted on it thereby permitting flow of the body fluid from the peritoneum through the valve housing and through the venous tube into an intrathoracic vein.
