Infusate containers
The invention relates to infusate containers and related systems and methods for housing infusates that can be added to a fluid flow path for use during dialysis. The infusate containers can include a filter partitioning the containers into a first and second compartment, a draw tube for drawing up fluid from a bottom portion, a cap, a fluid connector for delivery and withdrawal of fluid from the two compartments, and a fluid connector for connection to a dialysis system.
1. An infusate container for use in dialysis, comprising:
a container body;
a cap removably connected to a top portion of the container body; the cap having a fluid connector for connection to a dialysis system;
a draw tube downwardly extending through the container body; the draw tube connected to the cap; and
a filter connected to the container body; the filter separating the container body into the top portion and a bottom portion; and
the draw tube downwardly extending through the filter into the bottom portion; wherein the draw tube is held above a base of the container body.
2. The infusate container of claim 1 , further comprising an inwardly tapering portion in the bottom portion of the infusate container.
3. The infusate container of claim 1 , further comprising a removable film on a top side of the cap.
4. The infusate container of claim 1 , the filter connected to the container body by any of glue, heat sealing, or welding.
5. The infusate container of claim 1 , wherein the filter is either a mesh or a frit filter.
6. The infusate container of claim 1 , wherein the fluid connector is a bi-channel connector.
7. The infusate container of claim 6 , wherein the bi-channel connector has a first channel fluidly connected to the draw tube.
8. The infusate container of claim 1 , further comprising a visual indicator indicating a substance inside the container body.
9. The infusate container of claim 8 , wherein the visual indicator is a colored band.
10. The infusate container of claim 1 , wherein the draw tube is molded to the cap.
11. The infusate container of claim 1 , further comprising at least one support member, wherein a first end of the at least one support member is connected to the draw tube and a second end of the at least one support member in is contact with the container body.
12. The infusate container of claim 1 , wherein the dry chemicals are selected from sodium bicarbonate or sodium chloride.
13. A dialysis system, comprising:
a dialysis machine comprising:
(i) a dialysate flow path;
(ii) one or more fluid connectors fluidly connecting one or more infusate containers to the dialysate flow path wherein the infusate containers comprise: a container body; a cap removably connected to a top portion of the container body; the cap having a fluid connector for connection to the dialysis system; a draw tube downwardly extending through the container body and the draw tube held above a base of the container body; the draw tube connected to the cap; and a filter connected to the container body; the filter separating the container body into the top portion and a bottom portion; the draw tube downwardly extending through the filter; wherein the infusate containers contain a solid infusate; and
(iii) at least one pump connected to a fluid line fluidly connected to one or more fluid connectors.
14. The dialysis system of claim 13 , wherein the fluid connector is a bi-channel connector.
15. The dialysis system of claim 13 , wherein an infusate container contains sodium chloride, sodium bicarbonate, a cation infusate, or combinations thereof.
16. The dialysis system of claim 14 , 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 an infusate container to a second fluid line.
17. The dialysis system of claim 13 , further comprising an infusate frame, the infusate frame housing the infusate containers.
18. The dialysis system of claim 17 , the infusate frame having one or more apertures for housing the one or more infusate containers; the one or more apertures sized or shaped complementary to the one or more infusate containers.
