Abstract

An ostomy appliance body side member or an ostomy appliance comprising an adhesive wafer having a first adhesive surface for securing the appliance to the user'"'"'s skin, said wafer having a second surface being covered with a carrier sheet which wafer has a hole for receiving a stoma wherein a part of the adhesive wafer surrounding the stoma shows balanced plastic and elastic properties allowing an adaptation of the size of the hole of the ostomy appliance to a stoma by enlarging the hole for accommodating the stoma by rolling up the inner rim thereof forming a torus and wherein a part of the second surface of the wafer surrounding the hole shows surface properties compatible with the first adhesive surface of the adhesive wafer locking the torus to the second surface in its rolled position by the contact between the second surface and the first adhesive surface enables a simple, safe and reliable customisation of the hole of a body side member without the use of tools and at the same time provides means for reducing the risk of causing injury to or constriction of the stoma.

Claims

1-18. -18. (canceled)

19. An ostomy appliance body side member comprising an adhesive wafer having a first adhesive surface for securing the appliance to the users skin and a second surface being covered with a carrier sheet, said wafer having a hole for receiving a stoma and wherein the part of the adhesive wafer surrounding the stoma showing balanced plastic and elastic properties characterized in that the part of the second surface surrounding the hole for receiving a stoma is provided with a hydrophobic adhesive compatible with the first adhesive surface of the adhesive wafer allowing an adaptation of the size of the hole of the ostomy appliance to accommodate a stoma by enlarging the hole by rolling up the inner rim of the hole, to form a torus being locked in its rolled up position by the contact to the surface surrounding the stoma.

20. A body side member as claimed in claim 19 wherein the torus is locked to the second surface in its rolled position by the contact between the second surface and the first adhesive surface.

21. A body side member as claimed in claim 19, wherein the adhesive wafer is made from an adhesive comprising hydrocolloids.

22. A body side member as claimed in claim 19, wherein the carrier sheet is absent on a central part of the second surface surrounding the stoma.

23. A body side member according to claim 22 where the hydrophobic adhesive stretches under the edge of the carrier sheet.

24. A body side member as claimed in claim 19 wherein a release liner protects the second adhesive surface.

25. A body side member as claimed in claim 19, wherein a carrier sheet extends to the central part of the wafer.

26. A body side member as claimed in claim 25, wherein the carrier sheet on a central part of the second surface of the adhesive wafer surrounding the stoma is provided with a weakening pattern.

27. A body side member as claimed in claim 19, wherein the part of the adhesive wafer surrounding the stoma is in the form of an exchangeable sealing member disposed in a hole of the wafer and having a hole for accommodating a stoma.

28. A body side member as claimed in claim 19, which is provided with coupling means for releasable attachment of a receiving bag.

29. A body side member as claimed in claim 28, wherein the coupling means are matching coupling rings.

32. A method of applying an ostomy appliance body side member as claimed in claim 19, comprising enlarging the hole by rolling up the inner rim of the hole, to form a torus being locked in its rolled up position by the contact to the surface surrounding the stoma.

33. A method of applying an ostomy appliance body side member as claimed in claim 20, comprising optionally removing the release liner, enlarging the hole by rolling the inner rim of the hole adapting of the hole to the size of the stoma forming a torus, locking the torus to the second surface in its rolled position by contact between the second surface and the first adhesive surface, aligning the stoma and the hole of the ostomy appliance body side member for accommodating the stoma and placing the body side member on the abdomen of the ostomate with the stoma projecting into the hole.

34. A method of applying an ostomy appliance body side member as claimed in claim 27 comprising a) locating the stoma and aligning the stoma and the hole of the body side member and placing the body side member on the abdomen of the ostomate with the stoma projecting into the hole, b) enlarging the hole of the sealing member by rolling the inner rim of the hole of the sealing member forming a torus, c) adapting the hole to the size of the stoma, d) locking the torus to the second surface of the sealing member in its rolled position by contact between the adhesive surface and the second surface of the sealing member, e) aligning the stoma and the second hole of the ostomy sealing member and f) placing the same in the first hole of the body side member on the abdomen of the ostomate with the stoma projecting into the second hole.

35. A body side member according to claim 19 wherein a receiving bag is secured to the carrier sheet on the second surface and the body side member and the bag is a one-piece ostomy appliance.

36. A method of applying a one-piece ostomy appliance according to claim 35 comprising enlarging the hole by rolling the inner rim of the hole adapting of the hole to the size of the stoma forming a torus, locking the torus to the first surface in its rolled position by contact between the second surface and the first adhesive surface, aligning the stoma and the hole of the ostomy appliance for accommodating the stoma and placing the ostomy appliance on the abdomen of the ostomate with the stoma projecting into the hole.

30. An ostomy sealing member in the form of a mouldable mass or ring having a first adhesive surface which shows a sufficient adhesiveness to adhere to the skin and to seal around a stoma and between the stoma and an ostomy appliance adapted to receive secretions from the stoma, which sealing member has a second surface facing away from the user, optionally being covered by a top film, said sealing member having a hole for accommodating a stoma and said sealing member having balanced plastic and elastic properties allowing an enlargement—

of the hole for receiving a stoma by rolling up the inner rim of the hole to form a torus before placing the sealing member around the stoma and wherein a part of the second surface surrounding the hole is provided with a hydrophobic adhesive, which is compatible with the first adhesive surface

31. A sealing member as claimed in claim 30, wherein the sealing member is made from an adhesive comprising hydrocolloids.
