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