Abstract

A prosthetic abdomen for peritoneal dialysis training is provided. The prosthetic abdomen is in the form of a belt having an inner layer of material, an outer layer of material, and a pouch formed between the inner layer of material and the outer layer of material. A belt fastener is provided at one or both ends of the belt. The outer layer of material has an inner surface partially defining the pouch, and an outer surface having a skin tone color. The positioning of the belt and skin tone color can be selected to mimic the actual peritoneum of a patient. The pouch is expandable to hold a bag of liquid having a volume of at least 1000 milliliters (ml). A method of training a patient to carry out a peritoneal dialysis self-treatment, using the prosthetic abdomen, is also provided.

Claims (42)

1. A prosthetic abdomen for peritoneal dialysis training, comprising:

a belt having a bottom, a top, a front, a front length of at least ten inches, a total length of at least 20 inches, a height of at least three inches along the front length, a first end, a second end, an inner layer of material, an outer layer of stretchable material, a pouch formed in the front between the inner layer of material and the outer layer of stretchable material, an opening formed through the outer layer of stretchable material, a midline at half of the height, a pouch fastener at or adjacent a top of the pouch, and a belt fastener at or adjacent at least one of the first end and the second end, for fastening the first end and the second end together, wherein

the inner layer of material and the outer layer of stretchable material are connected together at or adjacent the bottom of the belt to define a bottom of the pouch,

the outer layer of stretchable material has an inner surface partially defining the pouch, and an outer surface, and

the pouch is expandable to hold a volume of at least 1000 milliliters (ml).

2. The prosthetic abdomen of claim 1 , wherein the outer surface of the outer layer of stretchable material has a skin tone color, and the skin tone color is selected from beige, tan, brown, and black.

3. The prosthetic abdomen of claim 1 , wherein the opening comprises a through-hole having a diameter of at least ⅛ inch.

4. The prosthetic abdomen of claim 1 , further comprising a bag of liquid in the pouch, wherein the bag of liquid contains a volume of at least 1000 ml of liquid, the bag comprises a catheter extending therefrom, and the catheter extends through the opening.

5. The prosthetic abdomen of claim 1 , wherein the belt fastener comprises one or more of a hook and loop fastener, a button, a zipper, a snap fastener, a magnetic fastener, and a lace.

6. The prosthetic abdomen of claim 1 , wherein the pouch fastener comprises one or more of a hook and loop fastener, a button, a zipper, a snap fastener, a magnetic fastener, and a lace.

7. The prosthetic abdomen of claim 1 , wherein the belt fastener comprises a hook fastener at one of the first end and the second end, a loop fastener at the other of the first end and the second end, and the pouch fastener comprises a snap fastener.

8. The prosthetic abdomen of claim 1 , wherein the inner layer of material and the outer layer of stretchable material are connected together by a line of stitching, to define the bottom of the pouch.

9. The prosthetic abdomen of claim 8 , wherein the inner layer of material and the outer layer of stretchable material are connected together along first and second vertical seams to define left and right inside edges of the pouch.

10. The prosthetic abdomen of claim 1 , wherein the inner layer of material has an inner surface that partially defines the pouch, and an outer surface intended to contact a user's skin, and the outer surface of the inner layer of material comprises at least one of a nylon-spandex blend material and a foamed neoprene material.

11. The prosthetic abdomen of claim 1 , wherein the belt further has a centerline, the pouch fastener includes at least one fastener along the centerline, and the opening is offset from the centerline.

12. The prosthetic abdomen of claim 1 , wherein the pouch has a top opening, the inner layer of material and the outer layer of stretchable material are connected together by a line of stitching along substantially the entire bottom of the belt, and the inner layer of material and outer layer of stretchable material are connected together along substantially the entire top of the belt except at the top opening of the pouch.

13. The prosthetic abdomen of claim 1 , wherein the pouch is expandable to hold a 2500 ml, or larger, bag of liquid, a 2500 ml or larger bag of liquid is disposed in the pouch, and the bag of liquid in the pouch contains peritoneal dialysis solution.

14. The prosthetic abdomen of claim 1 , wherein the pouch has a length of at least eight inches.

15. The prosthetic abdomen of claim 1 resting against an abdomen, wherein the front of the prosthetic abdomen rests against the abdomen, the abdomen has a skin tone, the outer surface of the outer layer of stretchable material has a skin tone, and the skin tone of the outer surface of the outer layer of stretchable material matches the skin tone of the abdomen.

16. A method of training a user on how to perform peritoneal dialysis on the user, the method comprising:

placing the prosthetic abdomen of claim 1 around the abdomen of the user such that the front of the prosthetic abdomen rests against the abdomen of the patient user;

fastening the first end and the second end together at the back of the patient user;

placing an empty bag having a catheter attached thereto, in the pouch;

threading the catheter through the opening;

filling the empty bag, while the empty bag is in the pouch, with liquid fed through the catheter, to fill the bag, form a filled bag, and mimic a peritoneal dialysis fill step; and

draining the filled bag through the catheter, while the filled bag remains in the pouch, to empty the bag and mimic a peritoneal dialysis drain step.

17. The method of claim 16 , further comprising waiting at least ten minutes between the filling and the draining to mimic a peritoneal dialysis dwell step.

18. The method of claim 16 , wherein the catheter has a distal end and a cap closing the distal end, and the method further comprises:

removing the cap prior to the filling;

installing the cap on the distal end after the filing; and

removing the cap for a second time prior to the draining.

19. The method of claim 16 , wherein the catheter includes a catheter clamp thereon, and the method further comprises:

opening the catheter clamp prior to the filling;

closing the catheter clamp after the filling; and

opening the catheter clamp for a second time, prior to the draining.

20. The method of claim 16 , wherein the catheter has a distal end and the method further comprises cleaning the distal end of the catheter prior to the filling.

21. A method of training a user on how to perform peritoneal dialysis on the user, the method comprising:

resting the prosthetic abdomen of claim 1 against the abdomen of the user such that the front of the prosthetic abdomen rests against the abdomen of the user;

placing an empty bag having a catheter attached thereto, in the pouch;

threading the catheter through the opening;

filling the empty bag, while the empty bag is in the pouch, with liquid fed through the catheter, to fill the bag, form a filled bag, and mimic a peritoneal dialysis fill step; and

draining the filled bag through the catheter, while the filled bag remains in the pouch, to empty the bag and mimic a peritoneal dialysis drain step.
