Abstract

A seal for fitting around a stoma, comprising a single, flexible, adhesive material having a body in the shape of a split ring, having a first face for attaching to a peristomal surface, a second face for attaching to an ostomy appliance, a wall extending from the first face to the second face and providing an outer wall surface and an inner wall surface which defines an aperture for receiving the stoma, and a first end and a second end spaced apart to define an opening which extends from the outer wall surface to the inner wall surface, wherein the single material and oval, split ring shape of the seal causes the seal to be manipulable to fit around the stoma. Related methods and systems are also disclosed.

Claims

1. A seal for fitting around a stoma, comprising a single, flexible, adhesive material having a body formed in the shape of a split ring, comprising

a first face for attaching to a peristomal surface,

a second face for attaching to an ostomy appliance,

a wall extending from the first face to the second face and providing an outer wall surface and an inner wall surface which defines an aperture for receiving the stoma, and

a first end and a second end spaced apart to define an opening which extends from the outer wall surface to the inner wall surface,

wherein the single material and oval, split ring shape of the seal causes the seal to be manipulable to fit around the stoma.

2. A seal according to claim 1 in which the outer wall surface forms a substantially oval shape.

3. A seal according to claim 1 in which the outer wall surface forms a substantially circular shape.

4. A seal according to claim 1 in which the inner wall surface forms a substantially oval aperture.

5. A seal according to claim 1 in which the inner wall surface forms a substantially circular aperture.

6. A seal according to claim 1 in which the seal is stretchable to fit around the stoma.

7. A seal according to claim 1 in which the seal is moldable to substantially conform with the stoma and is moldable to substantially conform with a peristomal surface.

8. A seal according to claim 1 in which the seal comprises a flexible, adhesive hydrocolloid material.

9. A seal according to claim 1 in which the first and second ends comprise flat end walls having rounded corners.

10. A seal according to claim 1 in which the first and second ends comprise substantially rounded end walls.

11. A seal according to claim 1 in which the first and second ends comprise substantially flat end walls.

12. A seal according to claim 1 in which the first and second ends, in use, overlap or abut to form a seal around the stoma.

13. A seal according to claim 1 in which the first end and/or the second end is tearable to remove excess seal.

14. A seal according to claim 1 in which the first and second faces are generally flat.

15. A seal according to claim 1 in which the first and second faces are shaped to fit to a peristomal surface.

16. A seal according to claim 1 in which the wall is sloped with respect to the first and second faces.

17. A medical device system comprising:

an ostomy appliance; and

a seal for fitting around a stoma, the seal comprising a single, flexible, adhesive material having a body formed in the shape of a split ring, comprising

a first face for attaching to a peristomal surface,

a second face for attaching to an ostomy appliance,

a wall extending from the first face to the second face and providing an outer wall surface and an inner wall surface which defines an aperture for receiving the stoma, and

a first end and a second end spaced apart to define an opening which extends from the outer wall surface to the inner wall surface,

wherein the single material and oval, split ring shape of the seal causes the seal to be manipulable to fit around the stoma.

18. The medical device of claim 17, wherein the ostomy appliance is an ostomy bag comprising:

a pouch with a ring flange, the ring flange being configured to be adhered to the second face of the seal so that output from the stoma is collected in the pouch.

19. The medical device of claim 18, wherein the ring flange is also adhered to the peristomal surface.

20. A method of using a seal for fitting around a stoma, the seal comprising a single, flexible, adhesive material having a body formed in the shape of a split ring, comprising

a first face for attaching to a peristomal surface,

a second face for attaching to an ostomy appliance,

a wall extending from the first face to the second face and providing an outer wall surface and an inner wall surface which defines an aperture for receiving the stoma, and

a first end and a second end spaced apart to define an opening which extends from the outer wall surface to the inner wall surface,

wherein the single material and oval, split ring shape of the seal causes the seal to be manipulable to fit around the stoma, the method comprising the steps of:

placing the seal around a stoma, such that the stoma is received in the aperture of the seal and the first face lies against a peristomal skin surface and manipulating the seal to fit relatively closely around the stoma, then pressing the seal against the peristomal skin surface to enhance adherence of the seal to the skin surface.
