  • 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.

  • Patent number: 7789849
    Abstract: A peritoneal dialysis system includes: (i) an enclosure; (ii) a stepper motor housed by the enclosure; (iii) a pump head in operable communication with the stepper motor; and (iv) a disposable unit including at least one flexible membrane attached to a rigid piece, the enclosure configured to receive the disposable unit such that the stepper motor can move the pump head towards and away from the flexible membrane to cause, (a) the flexible membrane to move outwardly with respect to the rigid piece as the pump head is moved away from the disposable unit, and (b) the flexible membrane to move inwardly with respect to the rigid piece as the pump head is moved away from the disposable unit.

  • 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.

  • Patent number: 7083719
    Abstract: A method, system and apparatus for performing peritoneal dialysis are provided. To this end, in part, a medical system is provided that includes (i) a liquid pump; (ii) tubing in communication with the liquid pump; and (iii) at least one processor that operates with the liquid pump to: (a) pump liquid through the tubing, the tubing having an end and a hydrophobic filter at the end, the filter allowing air but not the liquid to escape from the end of the tubing, (b) receive a signal indicating a pressure increase inside the tubing, and (c) cause the pumping to stop when air has been purged substantially from the tubing.

  • Patent number: 6929751
    Abstract: A method, system and apparatus for performing peritoneal dialysis are provided. To this end, in part, a member for removably securing a medical fluid tube is provided. The member includes a body providing a first fluid pathway and an opening for removably receiving an end of the medical tube. The first fluid pathway is placed in fluid communication with a second fluid pathway defined by the tube when the end of the tube is removably receiving. The member further includes a filter so positioned and arranged so as to cause fluid flowing through the first fluid pathway to pass through the filter, the filter allowing air but not liquid to flow through the first fluid pathway.

  • Patent number: 6764761
    Abstract: A method, system and apparatus for performing peritoneal dialysis are provided. To this end, in part, a film is provided. The film includes a layer of a polymer blend having from about 90% to about 99% by weight of a first component containing a styrene and hydrocarbon copolymer and from about 10% to about 1% of a high melt strength polypropylene.

  • Publication number: 20030220607
    Abstract: A method, system and apparatus for performing peritoneal dialysis are provided. To this end, in part, a peritoneal dialysis apparatus is provided that includes a body provided with an operating portion and a display, a mounting portion provided on the body for detachably mounting a cassette, a pumping actuating device for setting a diaphragm in a positive and negative pressure state to distribute fluid from the dialysis fluid container to the drained fluid container, and a heater for heating an amount of dialysis fluid. The apparatus further includes a flow path switching device for opening/closing a flow path switching portion in order to form a flow path through which the heated dialysis fluid is distributed into and drained from a peritoneal cavity of a patient, and a controller for controlling operation of the operating portion, the display, the pumping actuating device, the heater, and the flow path switching device.
