Abstract

Claims (29)

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

an inner layer of a first material;

an outer layer of a second material;

an opening formed through the outer layer;

a tube extending through the opening; and

a bag of liquid in fluid communication with the tube extending through the opening, wherein

the outer layer of second material has an outside surface that has a skin tone color.

2. The prosthetic abdomen of claim 1 , further comprising a pouch, wherein the inner layer of first material has a bottom edge, the outer layer of second material has a bottom edge, and the inner layer of first material and the outer layer of second material are connected together at or adjacent the bottom edge of the inner layer of first material and at or adjacent the bottom edge of the outer layer of second material, to define a bottom of the pouch.

3. The prosthetic abdomen of claim 2 , wherein the pouch is expandable.

4. The prosthetic abdomen of claim 2 , wherein the pouch is expandable to hold a volume of at least 1000 milliliters (ml).

5. The prosthetic abdomen of claim 2 , wherein the bag of liquid is inside the pouch.

6. The prosthetic abdomen of claim 1 , wherein the bag contains at least 1000 ml of the liquid.

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

8. The prosthetic abdomen of claim 1 , further comprising a belt fastener configured to fasten the prosthetic abdomen to an abdomen of a user.

9. The prosthetic abdomen of claim 8 , wherein the belt fastener comprises a first end, a second end, a first fastener at the first end, and a second fastener at the second end, and the first fastener and the second fastener are configured to fasten together.

10. The prosthetic abdomen of claim 1 , wherein the inner layer of first material and the outer layer of second material are connected together by a line of stitching.

11. The prosthetic abdomen of claim 1 , wherein the inner layer of first material and the outer layer of second material are connected together along seams to define left and right inside edges of a pouch.

12. The prosthetic abdomen of claim 11 , wherein the seams are vertical seams.

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

14. The prosthetic abdomen of claim 1 , wherein the outer layer of second material has a centerline, and the opening is offset from the centerline.

15. The prosthetic abdomen of claim 1 resting against an abdomen such that the outer surface of the outer layer of second material is exposed, wherein the abdomen has a skin tone color, and the skin tone color of the outer surface of the outer layer of second material matches the skin tone color 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 on the abdomen of the user such that the prosthetic abdomen rests against the abdomen of the user;

extending the tube through the opening; and

draining the bag of liquid through the tube to empty the bag of liquid and mimic a peritoneal dialysis drain step.

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

removing the cap prior to the draining.

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

opening the catheter clamp prior to the draining.
