    摘要： Pumping mechanisms for performing peritoneal dialysis and the like employ a pumping mechanism comprising a diaphragm (59) that operate in response to applied fluid pressure. Flexible tubing is attached to the pumping mechanism for carrying liquid to and from the patient's peritoneal cavity. An actuating station for pumping mechanism receives the pumping mechanism and attached tubing. A pressure transfer element (104) conveys fluid pressure to the diaphragm (59) for moving liquid through the cassette. An occluder element (138, 144) contacts and crimps closed the tubing attached to the cassette. A first reservoir (128) inflates with positive fluid pressure for contacting the pressure transfer element (104) to hold it in operative contact against the diaphragm (59). A second reservoir inflates with positive fluid pressure for contacting the occluding element (138, 144) to hold it away from crimping contact with the tubing. At least one of the first (128) and second (152) reservoirs also transports fluid pressure to the pressure transfer element for conveyance to the diaphragm.

    摘要： Systems and methods for peritoneal dialysis establish flow communication between a patient's peritoneal cavity [tube connector (35)] and a drain [tube connector (29)] through a pump chamber (P1, P2) having generally vertically spaced upper and lower regions [upper ports (64), lower ports (66)] and a diaphragm (59, 61). The systems and methods operate the pump chamber, with the upper and lower regions oriented generally vertically, by applying fluid pressure to the diaphragm (59, 61). The systems and methods direct liquid to the patient's peritoneal cavity only from the lower region of the pump chamber. In this way, the improved systems and methods collect air in the upper region of the vertically oriented pump chamber, while isolating the patient's peritoneal cavity from air in the pump chamber.
