  • Patent number: 10137235
    Abstract: An embodiment of a peritoneal dialysis system includes an enclosure, a door hingedly attached to the enclosure, a stepper motor housed by the enclosure, a solid pump piston in operable communication with the stepper motor and including a solid pump shaft attached to or integrally formed with a solid pump head, and a disposable unit contacting the enclosure and the door. The disposable unit includes a moveable membrane operable with the solid pump head. The stepper motor is configured to move the solid pump head towards and away from the disposable unit. The system further includes a position detection apparatus operable with the stepper motor and located to provide an output indicative of a position of the solid pump head relative to a reference position.

  • Publication number: 20180214625
    Abstract: An embodiment of a peritoneal dialysis system includes a peritoneal dialysis hardware unit having a housing with a first opening, a door coupled to the housing and having a second opening, and a solid pump piston having a solid piston shaft attached to or integrally formed with a solid piston head. The system also includes a stepper motor operable to cause the solid pump piston to translate; a disposable pumping unit having a first and a second opposing surface, and a fluid pump receptacle extending from the first and second surface to fit within the second opening. The hardware unit and pumping unit are structured and arranged to allow the pumping unit to be placed into the hardware unit such that the fluid pump receptacle is aligned with the first opening, the second opening, and the solid piston head when the door is closed against the housing.

  • Patent number: 7153286
    Abstract: The present invention provides automated peritoneal dialysis systems, methods of operating the systems and devices for performing same. A typical therapy performed by the present invention begins by draining dialysis solution that is already in the patient's peritoneal cavity. The system pumps fresh dialysate from one of a plurality of supply bags, through an in-line heater to the patient's peritoneal cavity. After a dwell period, the spent dialysate in the cavity is pumped out of the patient to a drain or other disposal means. The system then pumps fresh dialysate from the supply bags to the patient and the procedure is repeated as defined in the therapy protocol. The system can pump a last bag of dialysate to the peritoneal cavity for an extended dwell, such as a daytime dwell.
