Abstract

A peritoneal dialysis method includes (i) connecting smaller and larger supply containers to a junction, the smaller and larger supply bags both full of dialysate; (ii) allowing the junction to be connected to a patient'"'"'s transfer set; allowing the patient to drain through the junction; (iii) allowing the patient to fill from the smaller supply container; and (iv) allowing the patient to refill the smaller supply container from the larger supply container.

Claims

1. A peritoneal dialysis set comprising:

a larger supply container;

a smaller supply container sized to hold a single patient fill volume of dialysate;

a junction;

a supply tube connecting the larger supply container to the smaller supply container;

a fill tube connecting the smaller supply container to the junction; and

a drain tube connected to the junction.

2. The peritoneal dialysis set of claim 1, wherein the junction is one of a Y-junction and a T-junction.

3. The peritoneal dialysis set of claim 1, wherein the junction includes a patient connector configured to connect to a patients'"'"' transfer set.

4. The peritoneal dialysis set of claim 1, which includes first and second manually operated clamps for selectively clamping any two of the supply, fill and drain tubes.

5. The peritoneal dialysis set of claim 1, which includes a flow control device for selectively clamping any two of the supply, fill and drain tubes.

6. The peritoneal dialysis set of claim 1, wherein at least one of:

(i) the larger supply container is a six liter container; and

(ii) the smaller supply container is a two liter container.

7. The peritoneal dialysis set of claim 1, wherein at least one of:

(i) the drain tube is fitted with a removeable plug and (ii) the drain tube is sized to extend to and fit within a drain container when a patient connected to the set is sitting or standing.

8. The peritoneal dialysis set of claim 1, wherein the smaller supply container includes at least one of:

(i) a supply port connected to the supply tube and a fill port connected to the fill tube; and

(ii) apparatus for hanging the smaller supply container.

9. The peritoneal dialysis set of claim 1, which includes at least one cap to close the junction during at least one patient dwell.

10. The peritoneal dialysis set of claim 1, wherein the larger and smaller supply containers are initially full.

11. The peritoneal dialysis set of claim 1, wherein the larger and smaller supply containers are filled with different types of dialysate.

12. The peritoneal dialysis set of claim 11, wherein the larger and smaller supply containers are separated by a frangible plug, which is broken after the smaller supply container is emptied.

13. A peritoneal dialysis system for use with the set of claim 1, the system including at least one of:

(i) a drain container configured to receive and secure the drain tube and (ii) a patient transfer set configured to connect to the junction.

14. A peritoneal dialysis method comprising:

connecting smaller and larger supply containers to a junction, the smaller and larger supply bags both full of dialysate;

allowing the junction to be connected to a patient'"'"'s transfer set;

allowing the patient to drain through the junction;

allowing the patient to fill from the smaller supply container; and

allowing the patient to refill the smaller supply container from the larger supply container.

15. The peritoneal dialysis method of claim 14, wherein connecting the smaller and larger supply containers to the junction includes connecting the smaller supply container to the junction and connecting the larger supply container to the smaller supply container.

16. The peritoneal dialysis method of claim 14, wherein allowing the junction to be connected to the patient'"'"'s transfer set includes at least one of:

(i) providing a cap on the junction that is removed for connection; and

(ii) configuring the junction to be connected fluidly to the patients'"'"' transfer set.

17. The peritoneal dialysis method of claim 14, wherein allowing the patient to drain through the junction includes preventing flow from the supply container to the junction, preventing flow from the larger supply container to the smaller supply container, and urging flow from the patient to a drain.

18. The peritoneal dialysis method of claim 14, wherein allowing the patient to fill from the smaller supply container includes preventing flow from the junction to a drain, preventing flow from the larger supply container to the smaller supply container, and urging flow from the smaller supply container through the junction to the patient.

19. The peritoneal dialysis method of claim 18, wherein urging flow includes raising the smaller supply container above a patients'"'"' access point.

20. The peritoneal dialysis method of claim 14, wherein allowing the patient to refill the smaller supply container from the larger supply container includes preventing flow from the smaller supply container to the junction and urging flow from the larger supply container to the smaller supply container.

21. The peritoneal dialysis method of claim 20, wherein urging flow includes lowering the smaller supply container below the larger supply container.

22. The peritoneal dialysis method of claim 14, which includes allowing the patient to flush the junction by preventing flow from the larger supply container to the smaller supply container and urging flow from the smaller supply container, through the junction, to a drain.

23. The peritoneal dialysis method of claim 14, which includes allowing for a dialysate dwell by preventing (i) flow from the supply containers to the junction and (ii) flow from the junction to a drain.

24. The peritoneal dialysis method of claim 23, which further includes allowing the patient to disconnect the patients'"'"' transfer-set from the junction during the dialysate dwell.

25. The peritoneal dialysis method of claim 14, wherein filling from the smaller supply container and refilling the smaller supply container from the larger supply container includes filling a first type of dialysis fluid from the smaller supply container and refilling a second type of dialysis fluid from the larger supply container.
