摘要:
A peritoneal dialysis system comprising: a dialysis machine including a vacuum chamber and a pump actuator operable with a pump shaft extending to a pump head, the pump shaft moveable within the vacuum chamber; a pumping cassette including a rigid portion and a flexible membrane covering the rigid portion, the membrane flexible enough to contact the rigid portion; and wherein the dialysis machine is configured to be mated with the pumping cassette so as to hold a vacuum applied to the vacuum chamber and the flexible membrane, the vacuum operable to cause the flexible membrane to follow the pump head as the pump head is retracted from the rigid portion, the pump head operable to cause the flexible membrane to move into the rigid portion as the pump head is moved into the rigid portion.
摘要:
A method for aligning a disposable cassette (150) within a peritoneal dialysis machine (100) comprising the steps of: loading the disposable cassette (150) within the peritoneal dialysis machine; actuating a pump head (36) toward the disposable cassette; contacting a pumping chamber (168,172,174) of the disposable cassette with the pump head; using the pump head to shift the disposable cassette if need be into proper operational alignment with the pump head; and inflating a bladder (182) to lock the properly aligned disposable cassette in place.
