Abstract: PROBLEM TO BE SOLVED: To provide an automatic peritoneal dialysis system that provides patients with a dialyzate at various pressures so as to maintain the safety and comfortableness of the patients. SOLUTION: This automatic peritoneal dialysis system which performs peritoneal dialysis to the patients is provided with (a) a liquid pump which is operated by a fluid pressure so as to make a liquid to flow to and from the abdominal cavity of a patient, (b) a fluid conduit tube to and from the pump which supplies a fluid to the pump so as to operate the pump, and (c) a vacuum source which transmits a negative pressure to the pump. This system is also provided with (d) a positive pressure source which transmits a positive pressure to the conduit tube and pump, (e) a flow rate distributing valve which causes the liquid pump to feed the liquid to and from the abdominal cavity of the patient by controlling the flow velocity and pressure of the fluid from the positive pressure and vacuum sources through the fluid conduit tube.

Abstract: A variable pressure drive peritoneal dialysis system (10) has a pneumatic pressure system (16) for purging and controlling a flow of dialysate through a disposable dialysate cassette (23) of a disposable dialysate delivery set (21). The pneumatic pressure system (16) has a variable-opening flow proportional valve for supplying air at selected profiled pressure or vacuum to a pneumatic interface (18). The disposable dialysate cassette (23) has a diaphragm pump (P1, P2) actuable by the profiled air pressure or vacuum to move dialysate to and from a patient (28) via the disposable dialysate delivery set (21) at a desired profiled dialysate pressure.
