Abstract

A portable, flexible peritoneal dialysis system is disclosed. The system includes a flexible harness, such as canvas or cloth, to mount a stiff housing with a heater for holding and heating fresh dialysis fluid. The harness includes straps or other suspending devices for holding a second, flexible housing for a drain bag for holding sent dialysis fluid. The upper portion of the system includes a hook and a load cell for suspending the remaining portions. The load cell is used to measure the weight of the apparatus. By keeping track of the weight and the changes, the quantity of fluid removed from the patient, spent dialysate, is tracked, as is fresh dialysate infused into the patient. An electronics or control portion controls heating of the fresh dialysate, and operation of pumps and valves for moving the dialysate. This portion also includes alarms and communications equipment.

Claims

1. A peritoneal dialysis system, comprising:

a flexible mounting apparatus;

a first housing for a first container for fresh dialysis fluid mounted on the flexible mounting apparatus;

an electronics bay with a controller mounted on the first housing;

a flexible housing for a second container for spent dialysis fluid mounted on the flexible mounting apparatus at a lower height than the first housing;

a mount for holding the flexible mounting apparatus; and

a mass sensor between the mount and the flexible mounting apparatus.

2. The peritoneal dialysis system of claim 1, wherein the first housing further comprises a heater.

3. The peritoneal dialysis system of claim 1, further comprising a vacuum pump controlled by the controller.

4. The peritoneal dialysis system of claim 1, further comprising a wireless communication module connected to the controller.

5. The peritoneal dialysis system of claim 1, further comprising a visual or audio alarm connected to the controller.

6. The peritoneal dialysis system of claim 1, wherein the flexible housing comprises a canvas or cloth harness suspended by straps from the first housing.

7. The peritoneal dialysis system of claim 1, wherein the mount comprises a hook for suspending the flexible mounting apparatus.

8. A peritoneal dialysis system, comprising:

a flexible mounting apparatus;

a stiff housing with a heater for a first container for fresh dialysis fluid, the stiff housing mounted to the flexible mounting apparatus;

an electronics bay with a controller mounted on the stiff housing;

a conformable housing for a second container for spent dialysis fluid, the conformable housing suspended by the flexible mounting apparatus below the stiff housing;

a vacuum pump in operable communication with the controller;

a mount for holding the flexible mounting apparatus; and

a load cell between the mount and the flexible mounting apparatus.

9. The peritoneal dialysis system of claim 8, wherein a height of the conformable housing is adjustable by straps suspending the conformable housing.

10. The peritoneal dialysis system of claim 8, wherein the stiff housing is airtight and is capable of holding a vacuum or a pressure for pumping dialysis fluid.

11. The peritoneal dialysis system of claim 8, wherein a height of the flexible mounting apparatus is adjustable.

12. The peritoneal dialysis system of claim 8, wherein a height of the flexible mounting apparatus is adjustable by adjusting the mount and the load cell.

13. The peritoneal dialysis system of claim 8, further comprising interconnecting lines and a Y-connector for connecting to an access device of a patient.

14. The peritoneal dialysis system of claim 8, further comprising valves for controlling flow of fresh dialysis fluid from the first container to the patient and flow of spent dialysis fluid from the patient to the second container.

15. The peritoneal dialysis system of claim 8, further comprising a pump for pumping dialysis fluid.

16. A method for performing peritoneal dialysis, the method comprising:

mounting a dialysate drain bag of a portable, flexible peritoneal dialysis system in a first housing at a height lower than a peritoneum of a patient;

mounting a dialysate fill bag of the portable, flexible peritoneal dialysis system in a second flexible, deformable housing at a height higher than the peritoneum of the patient, wherein the flexible peritoneal dialysis system includes the first and second housings and wherein the first housing and second housing are mounted within the flexible peritoneal dialysis system with freedom to move with respect to one another;

heating the dialysate fill bag with a heater of the portable, flexible peritoneal dialysis system until a desired temperature is achieved;

draining spent dialysate into the drain bag using a pump or a vacuum until a desired mass of spent dialysate is achieved;

filling the peritoneum with fresh dialysate using gravity or a pump until a desired mass of dialysate fill is achieved.

17. The method of claim 16, sending a signal if the desired mass of drained dialysate or fill dialysate is not achieved within a desired time or if the desired mass is exceeded.

18. The method of claim 16, further comprising adjusting a height of the drain bag.

19. The method of claim 16, further comprising adjusting a height of the portable, flexible peritoneal dialysis system.

20. The method of claim 16, further comprising sending a status of a peritoneal dialysis therapy session to a remote computer.

21. The method of claim 16, further comprising calculating the desired mass of dialysate fill or spent dialysate.
