Abstract

A portable dialysis cabinet for use in dialysis. The portable dialysis cabinet can have a size and weight that facilitates easy movement of the cabinet from one location to another with relative ease. The portable dialysis cabinet can have additional features necessary to facilitate portability, such as wheels and a handle. In general, the portable dialysis cabinet can contain all the necessary components for performing a dialysis session.

Claims

1. A portable dialysis cabinet, comprising:

a dialysis system;

at least two wheels disposed on a bottom surface of the dialysis cabinet;

a first pair of opposing doors hingeably disposed on the dialysis cabinet creating when said doors are closed a first and second interior portions of the dialysis cabinet, the first pair of opposing doors having a first door hinged vertically on a front left side of the dialysis cabinet and a second door hinged vertically on a front right side of the dialysis cabinet, wherein the first door and second door are capable of being open during priming of the dialysis system;

a stowable user interface;

wherein the dialysis cabinet comprises a recess for stowing the stowable user interface;

at least one attachment for a therapy cassette;

a locking mechanism for locking the therapy cassette into the portable dialysis cabinet;

and wherein the user interface in a deployed position provides access to the locking mechanism.

2. The portable dialysis cabinet of claim 1, further comprising a handle disposed on the exterior portion of the dialysis cabinet.

3. The portable dialysis cabinet of claim 2, wherein the handle is a telescoping handle.

4. The portable dialysis cabinet of claim 1, wherein the stowable user interface is in electronic communication with a control module.

5. The portable dialysis cabinet of claim 4, wherein the stowable user interface comprises one or more of a keyboard, a touch screen, a display screen, a mouse, a microphone, and a speaker.

6. The portable dialysis cabinet of claim 1, further comprising one or more fluid connection ports on the interior portion of the dialysis cabinet.

7. The portable dialysis cabinet of claim 6, wherein the one or more fluid connections comprise one or more jumpered ports in fluid connection with one or more components selected from the group consisting of:

a sorbent cartridge;

a dialyzer, a water reservoir, a cation infusate source, and an ultrafiltrate reservoir, the one or more jumpered ports and one or more components completing a controlled compliant dialysis flow path.

8. The portable dialysis cabinet of claim 1, wherein the therapy cassette comprises one or more of a dialyzer, a degassing module, a cation concentrate reservoir, an ammonia sensing module, a bicarbonate cartridge and a sodium chloride cartridge.

9. The portable dialysis cabinet of claim 8 wherein at least one of the contents of the therapy cassette and fluid connections are detachable.

10. The portable dialysis cabinet of claim 9, further comprising a cleaning manifold;

the cleaning manifold comprising at least one jumper, wherein the at least one jumper creates a fluid pathway connecting an inlet and an outlet of at least one detachable component of the therapy cassette.

11. The portable dialysis cabinet of claim 1, wherein the first door of the first pair of opposing doors comprises a mounting surface for mounting a sorbent cartridge, and further comprising a second mounting surface on the second door of the first pair of opposing doors for mounting one or more of a water reservoir and a drain reservoir.

12. The portable dialysis cabinet of claim 1 further comprising at least one sensor capable of sensing whether at least one component of the portable dialysis cabinet is properly mounted.

13. The portable dialysis cabinet of claim 1, wherein the locking mechanism is a lever configured to close over the therapy cassette to lock the therapy cassette in place.

14. The portable dialysis cabinet of claim 1 wherein the dialysis system comprises one or more of a dialyzer, a sorbent cartridge, a dialysate pump, a water reservoir, a cation infusate source, a degassing module, and a heater.

15. The portable dialysis cabinet of claim 1 wherein the dialysis system is a controlled compliant dialysis system.

16. The portable dialysis cabinet of claim 1, wherein the user interface comprises a display screen, and wherein the user interface is stowable into the exterior recess with the display on the interior of the exterior recess.

17. The potable dialysis cabinet of claim 1, wherein the first door opens leftward relative to the front left side away from a main body of the dialysis cabinet and the second door opens rightward relative to the front right side away from the main body of the dialysis cabinet.

18. The potable dialysis cabinet of claim 1, wherein the first door opens by swinging about a first vertical axis defined by a hinged front left side of the dialysis cabinet and the second door opens by swinging about a second vertical axis defined by a hinged front right side of the dialysis cabinet.

19. The portable dialysis cabinet of claim 12, wherein the at least one sensor is capable of sensing whether a sorbent cartridge is properly mounted on the opposing doors.

20. The potable dialysis cabinet of claim 1, wherein the doors are capable of being opened to create access to the fluid connection ports.

21. The portable dialysis cabinet of claim 1, wherein the first door is vertically hinged on a right side of the portable dialysis cabinet and the second door is vertically hinged on a left side of the portable cabinet wherein the first door and second door form a portion of a front of the portable dialysis cabinet in a closed position.
