Abstract

A modular assembly for a portable hemodialysis system may include a dialysis unit, e.g., that contains suitable components for performing hemodialysis, such as a dialyzer, one or more pumps to circulate blood through the dialyzer, a source of dialysate, and one or more pumps to circulate the dialysate through the dialyzer, and a power unit having a housing that contains suitable components for providing operating power to the pumps of the dialysis unit. The power unit may be selectively connected to the dialysis unit and provide power (e.g., pneumatic power in the form of pressure and/or vacuum) to the dialysis unit for the pumps when connected to the dialysis unit, but may be incapable of providing power to the dialysis unit when disconnected from the dialysis unit. The dialysis unit and the power unit are sized and weighted to each be carried by hand by a human.

First claim

What is claimed is:

1. A kit comprising a three-prong reagent supply connector and a three-prong disinfection connector for a hemodialysis apparatus, each of said three-prong reagent supply connector and said three-prong disinfection connector comprising three parallel prongs including first and second outer prongs arranged in a common plane, and a center prong arranged above the common plane, the three parallel prongs of the reagent supply connector and the disinfection connector being arranged to allow connection of the three parallel prongs to corresponding receiving holes of a connection point of the hemodialysis apparatus in only a single orientation of the connector;
wherein the reagent supply connector includes a first prong arranged to fluidly connect via a first supply line to an outlet of a first container for a first reagent;
a second prong arranged to fluidly connect via a second supply line to a second container for a second reagent; and
a center prong arranged to fluidly connect via a center supply line to an inlet of the first container,
wherein the disinfection connector comprises a common chamber into which channels of the three parallel prongs of the disinfect connector terminate so as to interconnect the channels, and
wherein the receiving holes of the connection point each connect with separate flow lines of the hemodialysis apparatus, and the disinfection connector interconnects the receiving holes of the connection point of the hemodialysis apparatus, permitting disinfection of each of said flow lines during a disinfect procedure.

2. The kit of claim 1 , wherein the first container for the first reagent includes a bicarbonate material used in generating a dialysate for the hemodialysis apparatus.

3. The kit of claim 2 , wherein the center supply line is a water supply line that provides water to the first container.

4. The kit of claim 3 , wherein the first supply line is a bicarbonate supply line that provides bicarbonate material and water to the connector.

5. The kit of claim 1 , wherein the second supply line is an acid supply line that provides acid material to the connector.

6. The kit of claim 5 , wherein the acid supply line includes a container connector arranged to connect with the second container.

7. The kit of claim 6 , further comprising an acid bag spike removably engaged with the container connector of the acid supply line.

8. The kit of claim 7 , wherein the acid bag spike includes a spike member and a pair of spring clips at an end of the acid bag spike opposite the container connector of the acid supply line.

9. The kit of claim 8 , wherein the spike member and the spring clips are molded as a single unitary piece.

10. The kit of claim 9 , wherein the acid bag spike includes a pinch clamp to occlude flow in the acid bag spike.

11. The kit of claim 9 , wherein the spike member and the spring clips are arranged to enable the spring clips to maintain engagement of the spike member with an acid supply.

12. The kit of claim 11 , wherein the spring clips are manipulable to allow disengagement of the spring clips and the spike member from the acid supply.

13. The kit of claim 8 , wherein the spring clips are joined together at center portions by a connecting bar such that the spring clips and the connecting bar form an “H” shape.

14. The kit of claim 13 , wherein the spring clips include a barb member at a distal end.
