## Abstract

An ostomy barrier appliance for attaching an ostomy appliance to peristomal skin surrounding a stoma is provided. The ostomy barrier appliance includes a skin barrier, an inlet opening for receiving a stoma, and a convexity adjusting device arranged adjacent the skin barrier. The convexity adjusting device is configured to adjust the convexity of the skin barrier.

## Claims

### Claim 1

An ostomy barrier appliance for attaching an ostomy appliance to a peristomal skin surrounding a stoma, the ostomy barrier appliance comprising: a skin barrier comprising an adhesive; an inlet opening defined in the skin barrier for receiving a stoma; and a convexity adjusting device arranged adjacent the skin barrier; wherein the convexity adjusting device is configured to adjust a convexity and softness of the ostomy barrier appliance, wherein the convexity adjusting device includes a convex insert receiving structure attached to a pouch-side surface of the skin barrier and a plurality of convex inserts, wherein each of the plurality of convex inserts is configured to be received in the convex insert receiving structure and make contact with the skin barrier to provide the convexity and softness of the ostomy barrier appliance, wherein the convexity and softness of the ostomy barrier appliance are adjusted by selecting one of the plurality of the convex inserts having a desired depth and softness, wherein the plurality of convex inserts includes a first convex insert formed from a first material and a second convex insert formed from a second material, wherein the first material has a different softness than the second material.

### Claim 2 (depends on 1)

The ostomy barrier appliance of claim 1, wherein the ostomy barrier appliance includes a flange with a body-side coupling ring, wherein the flange is attached to a portion of the convexity adjusting device, wherein the body-side coupling ring is configured to mate with a pouch side coupling ring to attach an ostomy pouch to the ostomy barrier appliance.

### Claim 3 (depends on 1)

The ostomy barrier appliance of claim 1, wherein the convexity adjusting device is configured to provide a generally flat skin barrier and to increase the convexity of the skin barrier incrementally and to set the convexity of the skin barrier at a desired convexity.

### Claim 4 (depends on 1)

The ostomy barrier appliance of claim 1, wherein the ostomy barrier appliance is configured to provide a convexity depth of the skin barrier of about 0 mm to about 15 mm.

### Claim 5 (depends on 1)

The ostomy barrier appliance of claim 1, wherein the ostomy barrier appliance is configured to provide a convexity angle of the skin barrier of about 0° to about 60°, wherein convexity angle=tan−1(convexity depth/convexity width).
