Abstract

Claims (36)

1. An infusate sleeve, comprising:

a sleeve body;

a filter inside of the sleeve body and sealed to the sleeve body separating the sleeve body into a top portion and a bottom portion;

a rigid disk sealed to the top portion of the sleeve body; the rigid disk covering an opening in the top portion of the sleeve body;

a second opening in the bottom portion of the sleeve body;

a draw tube connected to the rigid disk; the draw tube downwardly extending from the rigid disk through the filter and into the bottom portion; and

a fluid connector connected to an outside of the rigid disk; the fluid connector in fluid connection with the draw tube.

2. The infusate sleeve of claim 1 , wherein the filter and rigid disk are heat sealed to the sleeve body.

3. The infusate sleeve of claim 1 , wherein the sleeve body is flexible.

4. The infusate sleeve of claim 1 , wherein the sleeve body is rigid.

5. The infusate sleeve of claim 1 , wherein the fluid connector is a bi-channel connector.

6. The infusate sleeve of claim 5 , wherein a first channel in the bi-channel connector is fluidly connected to the draw tube.

7. The infusate sleeve of claim 1 , further comprising a cup covering the opening in the bottom portion of the sleeve body; the cup sealed to the sleeve body.

8. The infusate sleeve of claim 7 , wherein the filter is sealed to the cup.

9. The infusate sleeve of claim 1 , wherein the filter is either a mesh or frit filter.

10. An infusate container, comprising:

an infusate container body;

the infusate sleeve of claim 1 inside the container body; and

a cap; wherein the fluid connector extends through an opening in the cap.

11. The infusate container of claim 10 , wherein the infusate sleeve is flexible.

12. The infusate container of claim 10 , wherein the infusate sleeve is rigid.

13. A method, comprising the steps of:

flowing water into the infusate container of claim 10 , wherein the infusate container contains a solid infusate;

dissolving at least a portion of the solid infusate to make an infusate solution; and

flowing the infusate solution into a dialysate flow path.

14. The method of claim 13 , wherein the step of flowing water into the infusate container comprises flowing water through a first channel of a bi-channel connector; and wherein the step of flowing the infusate solution into the dialysate flow path comprises flowing the infusate solution through a second channel of the bi-channel connector.

15. The method of claim 13 , wherein the step of dissolving at least a portion of the solid infusate to make an infusate solution comprises making a saturated infusate solution.

16. The method of claim 13 , wherein the solid infusate is sodium bicarbonate, sodium chloride, a cation infusate, or a combination thereof.

17. A dialysis system, comprising:

a dialysate flow path;

one or more fluid connectors fluidly connecting one or more infusate containers to the dialysate flow path;

wherein the one or more infusate containers comprise an infusate container body, the infusate sleeve of claim 1 inside the container body, and a cap; wherein the one or more fluid connectors extends through an opening in the cap;

at least one pump connected to a fluid line fluidly connected to the one or more fluid connectors.

18. The dialysis system of claim 17 , wherein the one or more fluid connectors are bi-channel connectors.

19. The dialysis system of claim 18 , wherein a first channel of the bi-channel connector fluidly connects the draw tube to a first fluid line; and wherein a second channel of the bi-channel connector fluidly connects the infusate sleeve to a second fluid line.

20. The dialysis system of claim 17 , wherein the infusate sleeve contains sodium chloride, sodium bicarbonate, a cation infusate, or combinations thereof.
