Abstract

Dialysis machines and methods for heating dialysate before delivery into a dialysis patient (e.g., peritoneal dialysis machines) may comprise a dialysis machine including one or more internal cooling components configured to expel heated air from the dialysis machine. A receptacle may be configured to receive one or more containers of dialysate. The one or more containers of dialysate may be positionable relative to the expelled heated air of the dialysis machine. The expelled heated air may be flowable around the one or more containers of dialysate to increase a temperature of the dialysate. The receptacle may include a stand for positioning the dialysis machine such that the expelled heated air is directed around the one or more containers of dialysate.

First claim

What is claimed is:

1. A system for heating dialysate before delivery into a dialysis patient, comprising:
a dialysis machine including one or more internal cooling components configured to expel heated air from the dialysis machine; and
a receptacle configured to receive one or more containers of dialysate, the one or more containers of dialysate being positionable relative to the expelled heated air of the dialysis machine, wherein the expelled heated air is flowable around the one or more containers of dialysate to increase a temperature of the dialysate;
wherein the receptacle includes:
a stand arranged and configured to position the dialysis machine thereon, the stand including one or more vents; and
a section arranged and configured to receive the one or more containers of dialysate therein, the section positioned below the stand and the one or more vents so that the expelled heated air is directed out of the dialysis machines through the one or more vents formed in the stand and into the section of the receptacle and around the one or more containers of dialysate.

2. The system according to claim 1 , wherein the one or more vents includes baffles for directing the expelled heated air around the one or more containers of dialysate.

3. The system according to claim 1 , wherein the receptacle is a movable cart.

4. The system according to claim 1 , wherein the one or more containers of dialysate are stackable in the section of the receptacle.

5. The system according to claim 4 , wherein the section is insulated for minimizing heat transfer from the one or more containers of dialysate to ambient air.

6. The system according to claim 1 , wherein the one or more internal cooling components includes a fan.

7. The system according to claim 6 , wherein during operation the dialysis machine generates internal heat resulting in heated air, wherein the fan is configured to simultaneously cool the dialysis machine and heat the one or more containers of dialysate by expelling the heated air from the dialysis machine and directing the expelled heated air to flow around the one or more containers of dialysate.

8. A method for heating dialysate before delivery into a dialysis patient, comprising:
operating a dialysis machine, the dialysis machine generating heated air in response to being operated;
expelling the heated air from the dialysis machine by one or more internal cooling components to cool the dialysis machine;
directing the expelled heated air around one or more containers of dialysate disposed in a receptacle; and
heating the dialysate by the expelled heated air;
wherein the dialysis machine is positioned on a stand of the receptacle and the one or more containers of dialysate are positioned in a first section of the receptacle, the first section being insulated for minimizing heat transfer from the one or more containers of dialysate to ambient air.

9. The method according to claim 8 , wherein the stand positions the dialysis machine vertically over the first section of the receptacle, the stand including one or more vents.

10. The method according to claim 9 , wherein the one or more vents includes baffles for directing the expelled heated air around the one or more containers of dialysate.

11. The method according to claim 8 , wherein the receptacle is a movable cart.

12. The method according to claim 9 , wherein the one or more containers of dialysate are stackable in the first section of the receptacle.

13. The method according to claim 8 , wherein the one or more internal cooling components includes a fan.

14. The method according to claim 13 , wherein during operation the dialysis machine generates internal heat resulting in heated air, wherein the fan is configured to simultaneously cool the dialysis machine and heat the one or more containers of dialysate by expelling the heated air from the dialysis machine and directing the expelled heated air to flow around the one or more containers of dialysate.
