Abstract

Claims (28)

1. A dialysis machine comprising:

a controller unit wherein the controller unit comprises:

a door having an interior face;

a housing with a panel wherein the housing and panel define a recessed region configured to receive the interior face of the door; and

a manifold receiver fixedly attached to the panel; and

a fluid supplying unit wherein the fluid supplying unit comprises:

a planar surface for receiving a container of fluid;

a scale integrated with the planar surface; and

a heater in thermal communication with the planar surface.

2. The dialysis machine of claim 1 , wherein the manifold receiver comprises at least one of contoured guides, pins, or latches.

3. The dialysis machine of claim 1 , wherein the panel is configured to provide access to a plurality of pumps.

4. The dialysis machine of claim 1 , wherein the panel is configured to provide access to four peristaltic pumps in a predefined alignment.

5. The dialysis machine of claim 4 , wherein the interior face comprises four pump shoes.

6. The dialysis machine of claim 5 , wherein, when the door is received into the recessed region, each of the four pump shoes aligns with one of four peristaltic pumps.

7. The dialysis machine of claim 5 , wherein at least one of the shoes is movably attached to the door by a member and spring.

8. The dialysis machine of claim 7 , wherein the member is a bolt.

9. The dialysis machine of claim 7 , wherein the controller unit further comprises a sensor configured to measure a movement of the member.

10. The dialysis machine of claim 1 , wherein the dialysis machine is configured to perform a dialysis treatment using approximately six liters of water, and wherein the water is from a non-sterile source.

11. The dialysis machine of claim 1 , wherein the manifold receiver is configured to receive a plastic substrate that defines a first flow path which is fluidically isolated from a second flow path.

12. The dialysis machine of claim 11 , wherein each of the first flow path and the second flow paths has a hydraulic diameter in a range of 1.5 mm to 7.22 mm.

13. The dialysis machine of claim 11 , wherein the molded plastic substrate is bonded to a plurality of tubing and wherein the plurality of tubing is bonded to a dialyzer.

14. The dialysis machine of claim 13 , wherein the controller unit further comprises a member connected to an exterior of the housing, and wherein the member is configured to physically receive the dialyzer.

15. The dialysis machine of claim 13 , wherein the fluid supplying unit further comprises a member connected to an exterior of the fluid supplying unit, and wherein said member is configured to physically receive the dialyzer.

16. The dialysis machine of claim 13 , wherein the plurality of tubing is adapted to be removably attached to a sorbent cartridge.

17. The dialysis machine of claim 16 , wherein the base unit further comprises a member connected to an exterior surface of the base unit, and wherein the member is configured to physically receive the sorbent cartridge.

18. The dialysis machine of claim 1 , wherein the controller unit comprises a bottom surface, and wherein the bottom surface comprises a first physical interface and a first data interface.

19. The dialysis machine of claim 18 , wherein the fluid supplying unit has a top surface and wherein the top surface comprises a second physical interface configured to complement the first physical interface and a second data interface capable of interfacing with the first data interface.

20. The dialysis machine of claim 1 , further comprising a sodium sensor in electromagnetic communication with the planar surface.
