Abstract

A body attachment wafer for an ostomy device is provided, which body attachment wafer has a stoma opening, and an adhesive layer. The adhesive layer is covered by a release layer, having an opening which corresponds to the stoma opening. The release layer is divided along at least one dividing line from the stoma opening to the periphery of the body attachment wafer, and the release sheet includes a first grip tab extending from the release sheet in the area of the at least one dividing line. The first grip tab is arranged to overlap the release sheet on the other side of the dividing line.

Claims (17)

1. A body attachment wafer for an ostomy device, comprising:

an adhesive layer defining a stoma opening; and

a release layer having an opening which is at least partially aligned with the stoma opening, wherein at least a portion of the release layer is configured to cover the adhesive layer,

wherein the release layer is divided along a dividing line extending from the stoma opening to a periphery of the body attachment wafer on opposing sides of the stoma opening, wherein the dividing line divides the release layer into a first part and a second part,

wherein the release layer comprises at least a first member that comprises two grip portions provided on opposing sides of the stoma opening, wherein each of the two grip portions of the first member has an inner side edge, wherein a portion of the first member is releasably attached to the adhesive layer in the first part, and wherein the grip portions extend away from the adhesive layer and are arranged to overlap the release layer on the second part, and wherein a distance between the inner side edges of the two grip portions of the first member is greater than a width of the stoma opening.

2. The body attachment wafer of claim 1 , wherein each of the inner side edges of the two grip portions of the first member is at an acute angle in relation to the dividing line.

3. The body attachment wafer of claim 1 , wherein the release layer comprises a second member that meets the first member along the dividing line such that each of the first and second members only partially encircles the stoma opening of the body attachment wafer, and wherein a portion of the second member is releasably attached to the adhesive layer in the second part.

4. The body attachment wafer of claim 3 , wherein the second member comprises two grip portions provided on opposing sides of the stoma opening, wherein each of the two grip portions of the second member has an inner side edge, wherein the second member grip portions extend away from the adhesive layer in the area of the dividing line, wherein a distance between the inner side edges of the two grip portions of the second member is greater than the width of the stoma opening.

5. The body attachment wafer of claim 4 , each of the inner side edges of the two grip portions of the second member is at an acute angle in relation to the dividing line.

6. The body attachment wafer of claim 4 , wherein the second member grip portions are folded back, and wherein the first member grip portions at least partially overlap the second release grip portions.

7. The body attachment wafer of claim 4 , wherein the first member grip portions and the second member grip portions have different lengths.

8. The body attachment wafer of claim 7 , wherein the second member grip portions are longer than the first member grip portions.

9. The body attachment wafer of claim 4 , wherein the first member grip portions are arranged to overlap the second member over the second part of the release layer.

10. The body attachment wafer of claim 1 , wherein the dividing line intersects the center of the stoma opening.

11. The body attachment wafer of claim 1 , wherein the first member grip portions have a length of at least 0.5 cm in the direction perpendicular to the dividing line.

12. The body attachment wafer of claim 1 , further comprising a plastic film on the side of the adhesive layer opposite to the release layer, wherein the release layer is stiffer than the plastic film.

13. An ostomy device comprising an ostomy pouch having an entrance opening and a body attachment wafer of claim 1 .
