ABSTRACT:
A post-operative patient drainage and irrigation apparatus, employing a simplified two-position valve to control the passage of fluids into and out of the body of the patient. A two-channel catheter directs body fluids into and out of the control valve. A first flexible tube directs irrigating solutions from a source into the control valve. A second flexible tube, attached at one end to the control valve, serves as a waste conduit from the said valve to a waste receptacle. Check valves carried in rubber squeeze bulbs in the first and second flexible tubes further control the direction of fluid flow and serve to clear obstructions in the apparatus. A simple control changes the two-position control valve position from one mode to another.
