Abstract: A peritoneal dialysis system comprising a housing, a stepper motor housed by the housing, a pump head in operable communication with the stepper motor, a disposable unit operable with the housing and an encoder operably coupled to the stepper motor. The disposable unit includes a membrane operable with the pump head and wherein the housing and the disposable unit are configured to allow a negative pressure to be applied to the pump head and the membrane. The stepper motor is configured to move the pump head towards and away from the disposable unit. The encoder is operable with a position detection apparatus located to detect a position of the pump head relative to a reference position.

Abstract: A fluid volumetric pumping system has a fluid pump and capacitor plates disposed around a pump chamber of the fluid pump. The capacitance between the capacitor plates changes as the volume of fluid in the pump chamber changes. An electrical circuit measures a change in the capacitance between the plates and outputs a signal indicative of the volume of fluid in the pump chamber. The pump having the capacitance sensor of the present invention fluidly connects to a patient. In an embodiment, a peritoneal dialysis system provides dialysate to the patient via the pump, and the capacitance sensor measures the volume of dialysate supplied to and drained from a peritoneal cavity of the patient.
