Abstract
A peritoneal dialysis system includes: (i) a hardware unit, the hardware unit including a pump actuator; (ii) a disposable unit received by the hardware unit, the disposable unit having a moveable membrane operable with the pump actuator, the pump actuator moveable towards and away from the disposable unit; and (iii) the hardware unit and disposable unit configured to hold a negative pressure between the pump actuator and the moveable membrane of the disposable unit, the negative pressure causing the moveable membrane to follow the pump actuator as the actuator is moved away from the disposable unit, the pump actuator and membrane positioned relative to each other such that the membrane moves with the pump actuator as the actuator is moved into the disposable unit.
