Abstract

The invention relates to infusate sleeves for use in dialysis and related systems and methods. The infusate sleeves include a sleeve body, a filter inside of the sleeve body, a rigid disk covering an opening in the top of the sleeve body, a draw tube connected to the rigid disk and extending downwardly into the sleeve body, and a fluid connector fluidly connected to the draw tube for connection to a dialysis system.

Claims

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.
