## Abstract

A prosthetic abdomen for peritoneal dialysis training is provided. The prosthetic abdomen has an inner layer of material and an outer layer of material. The outer layer of material has an outer surface having a skin tone color. An opening is formed through the outer layer. A tube extends through the opening. A bag of liquid is in fluid communication with the tube extending through the opening.

## Claims

### Claim 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.

### Claim 2 (depends on 1)

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.

### Claim 3 (depends on 2)

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

### Claim 4 (depends on 2)

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

### Claim 5 (depends on 2)

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

### Claim 6 (depends on 1)

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

### Claim 7 (depends on 1)

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

### Claim 8 (depends on 1)

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

### Claim 9 (depends on 8)

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.

### Claim 10 (depends on 1)

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.

### Claim 11 (depends on 1)

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.

### Claim 12 (depends on 11)

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

### Claim 13 (depends on 1)

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.

### Claim 14 (depends on 1)

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

### Claim 15 (depends on 1)

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.

### Claim 16 (depends on 1)

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.

### Claim 17 (depends on 16)

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.

### Claim 18 (depends on 16)

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.
