Abstract

The invention relates to an infusate caddy for carrying, organizing, and operating infusate containers containing solutes for preparing dialysate and related fluids for use in dialysis. The infusate containers can be seated in the infusate caddy, and the infusate containers removed from the infusate caddy for restocking, cleaning, or resupply, as needed. The infusate caddy can be positioned or seated in a receiving compartment of a dialysis machine, and can also be removed, as needed, from the dialysis machine.

Claims

1. An infusate caddy, comprising:

a bottom and at least one side extending upwardly from the bottom to form a shape complementary to a receiving compartment on a dialysis machine; and

at least one receiving compartment disposed on the infusate caddy complementary to an infusate container wherein the receiving compartment disposed on the infusate caddy has at least one fitting feature complementary to a corresponding fitting feature disposed on the infusate container.

2. The infusate caddy of claim 1, wherein the shape complementary to the receiving compartment on the dialysis machine is any one of a cube, disc, ovoid, or triangular prism.

3. The infusate caddy of claim 1, wherein the receiving compartment disposed on the infusate caddy is aligned to a fluid connector disposed on the dialysis machine;

and wherein the fluid connector forms a fluid connection between the infusate container and a flow path inside the dialysis machine.

4. The infusate caddy of claim 1, wherein the fitting feature complementary to the corresponding fitting feature of the infusate container is any one or more selected from the group consisting of:

(i) a protrusion, an indentation, a groove, and a ridge complementary to a corresponding indentation, a corresponding protrusion, a corresponding ridge, or a corresponding groove on the infusate container;

(ii) a specified geometry, size, or shape complementary to a corresponding geometry, a corresponding size, or a corresponding shape of the infusate container;

(iii) a visual indicator indicative of proper seating of the infusate container in the infusate caddy;

(iv) a locking mechanism keyed to the infusate container; and

(v) a specified geometry, size, or shape of a first infusate container and a complementary geometry, size, or shape of a second infusate container.

5. The infusate caddy of claim 1, further comprising an infusate caddy locking mechanism.

6. The infusate caddy of claim 1 wherein the infusate container is selected from the group consisting of a sodium bicarbonate container, a sodium chloride container, and a cation infusate container.

7. The infusate caddy of claim 6, wherein the infusate caddy further comprises a receiving compartment for a citric acid container.

8. The infusate caddy of claim 7, wherein the citric acid container has at least one fluid connection to allow recirculation between two or more fluid connectors.

9. A dialysis system comprising:

an infusate caddy having one or more infusate containers containing one or more solute;

a dialysis machine, comprising;

(i) a dialysate flow path;

(ii) a receiving compartment adapted to receive the infusate caddy;

(iii) one or more fluid connectors fluidly connectable to the one or more infusate containers; and

(iv) one or more pumps and one or more valves positioned on the one or more dialysis machine connectors;

the one or more pumps and one or more valves controlling fluid flow from the one or more infusate containers into the one or more fluid connectors.

10. The system of claim 9, further comprising a control system, wherein the control system controls the one or more pumps and the one or more valves to selectively flow fluid from the one or more infusate containers into the dialysate flow path.

11. The system of claim 9, wherein the dialysis machine connectors comprise a length of hose, wherein each length of hose is alternatively connectable to each of the one or more infusate containers.

12. The system of claim 9, further comprising a locking mechanism configured to keep the infusate caddy from moving after insertion into the receiving compartment when the locking mechanism is in a locked state;

wherein the locking mechanism is positionable in an open state wherein the open state allows removal of the infusate caddy.

13. The system of claim 9, wherein at least one pump is capable of moving fluid bi-directionally through the dialysis machine connectors.

14. The system of claim 9, wherein the infusate caddy is insertable into the receiving compartment in at least a first orientation and a second orientation;

wherein in the second orientation, the infusate caddy is rotated between from about 1°

to about 359°

from the first orientation;

wherein one or more infusate containers are connectable to the dialysis machine in the first orientation, but not in the second orientation.

15. The system of claim 14, wherein at least one fluid connector is sealed when the infusate caddy is inserted into the receiving compartment in the second orientation.

16. The system of claim 14, wherein at least two dialysis machine connectors are connected to allow recirculation flow between the connectors when the infusate caddy is inserted into the receiving compartment in the second orientation.

17. The system of claim 14, wherein the infusate caddy contains a disinfection container connectable to one or more of the fluid connectors when the infusate caddy is in the second orientation.

18. The system of claim 9, further comprising a second infusate caddy, wherein the second infusate caddy comprises one or more containers fluidly connectable to the one or more dialysis machine connectors;

and wherein the receiving compartment is adapted to receive the second infusate caddy.

19. The system of claim 18, wherein the second infusate caddy contains a disinfection container.

20. The system of claim 14, wherein the infusate caddy comprises a sensor;

wherein the sensor determines whether the infusate caddy is in the first orientation or the second orientation.
