Abstract

A valve integrity method for a medical fluid pump includes pumping fluid into the medical fluid pump while an outlet valve is closed and an inlet valve is open, closing the inlet valve while the outlet valve is closed, attempting to pump fluid out of the medical fluid pump while the inlet valve and the outlet valve are closed, and determining that at least one of the valves is leaking if a change in medical fluid volume within the medical fluid pump is detected.
