SYSTEM INCLUDING MACHINE INTERFACE FOR PUMPING CASSETTE-BASED THERAPIES
First Claim
1. A peritoneal dialysis machine comprising:
- a hardware unit including at least one pump actuator, at least one valve actuator and a disposable cassette interface, the cassette interface including;
a plate that faces the cassette when loaded into the machine;
at least one pump aperture defined by the plate;
at least one pump head moveable out of and retractable into the at least one pump aperture to operate a pumping portion of the cassette;
at least one valve aperture defined by the plate;
at least one valve apparatus moveable out of and retractable into the at least one valve aperture to operate a valve portion of the cassette;
at least one sensor aperture defined by the plate; and
at least one sensor located in the least one sensor aperture, the at least one sensor operable with a sensor portion of the cassette.

9. A peritoneal dialysis machine comprising:
-
an enclosure;
a plate carried by the enclosure, the plate facing a disposable cassette when the cassette loaded into the machine;
at least one pump aperture defined by the plate, at least one valve aperture defined by the plate, and at least one sensor aperture defined by the plate; and
a base aligned with the plate;
at least one pump actuator connected to the base and aligned with the at least one pump aperture defined by the plate, at least one valve actuator connected to the base and aligned with the at least one valve aperture defined by the plate, and at least one sensor connected to the base and aligned with the at least one sensor aperture defined by the plate. - View Dependent Claims (10, 11, 12, 13)

14. A peritoneal dialysis machine operable with a disposable cassette, the machine comprising:
-
a base including at least one pump actuator, at least one valve actuator and at least one sensor;
a door in a hinged relationship with respect to the base, the door including an inflatable bladder, the bladder inflatable configured to hold the disposable cassette in operable relationship with the at least one pump actuator, at least one valve actuator and at least one sensor. - View Dependent Claims (15, 16, 17, 18)

19. A peritoneal dialysis machine comprising
a cassette enclosure including two substantially flat surfaces configured to receive and hold a cassette which is at least partially flexible and which has predetermined flow paths, the cassette being aligned with the two surfaces, one of the substantially flat surfaces being fixed and the other being hinged relative to the fixed surface to hold the cassette in alignment with the flat surfaces when the hinged surface is closed; - and
an inflatable pad disposed in alignment with the two surfaces and on a hinged surface side of the cassette, the pad for compressing the cassette in an aligned and secure engagement between the two surfaces when the hinged surface is closed, the inflatable pad inflated via pressure to maintain the aligned and secure engagement of the cassette between the two surfaces. - View Dependent Claims (20)
