Abstract
A peritoneal dialysis system includes: an enclosure including an actuation surface and a door; a stepper motor housed by the enclosure; a pump head and a solid pump piston structurally linking the pump head to the stepper motor; and a disposable unit accepted by the enclosure, the disposable unit including a flexible membrane attached to a rigid piece, the actuation surface of the enclosure and the disposable unit so configured and arranged that when the stepper motor turns and consequently translates the solid pump piston and the pump head towards the door, the pump head physically contacts and stretches the membrane from a relaxed position to a stretched position, and when the stepper motor turns and consequently translates the solid pump piston and the pump head away from the door, the membrane follows the pump head and transitions from the stretched position to the relaxed position.
