Abstract

An ostomy appliance comprising an adaptor having a distal end adapted to be coupled to an ostomy wafer and a proximal end adapted to be coupled to a cap, said distal end having an opening in fluid communication with an opening in said proximal end.

Claims

1. An ostomy appliance comprising an adaptor having a distal end adapted to be coupled to an ostomy wafer and a proximal end adapted to be coupled to a cap, said distal end having an opening in fluid communication with an opening in said proximal end.

2. An ostomy appliance according to claim 1 comprising a cap adapted to be removably coupled to said adaptor.

4. An ostomy appliance according to claim 1, wherein said adaptor includes a sealing mechanism for sealing a wafer/adaptor interface.

16. An ostomy appliance according to claim 2, wherein said adaptor includes an opening for releasing gas flowing from the stoma.

21. An ostomy appliance according to claim 1, further comprising a sealing element adapted to be accommodated within an interior cavity of said adaptor.

24. An ostomy appliance according to claim 21 wherein said sealing element includes a compressed foam element.

29. An ostomy appliance according to claim 1, wherein said ostomy appliance does not press on the stoma when worn.

30. An ostomy appliance according to claim 1, wherein the axial length of the closed ostomy appliance is 12 mm or less.

48. The ostomy appliance according to claim 1 wherein the adaptor and the cap are integrally coupled.

49. The ostomy appliance according to claim 1, wherein the adaptor and the wafer are integrally coupled.

32. An ostomy component sealing system for sealing to an ostomy wafer comprising:

a housing adapted to be attached to said wafer; and

a sealing mechanism, formed of at least one element, that resists the flow of pressurized gasses through the housing-wafer interface.

33. The ostomy component sealing system of claim 32, wherein the at least one sealing mechanism element comprises an element integrally formed in the housing which presses against a surface of the wafer to form a seal that resists the outflow of gasses under pressure from the stoma.

34. The ostomy component sealing system of claim 32, wherein the at least one sealing mechanism element comprises an element integrally formed in the wafer which presses against a surface of the housing to form a seal that resists the outflow of gasses under pressure from the stoma.

35. The ostomy component sealing system of claim 32, wherein the at least one sealing mechanism element comprises a separate element contained within a cavity of the wafer which presses against a surface of at least one of the housing and the stoma to form a seal that resists the outflow of gasses under pressure from the stoma.

36. The ostomy component sealing system of claim 32, wherein the housing comprises the housing of an ostomy cap.

37. The ostomy component sealing system of claim 32, wherein the housing comprises a lumen having a proximal end, and is attached to a collapsed collection bag which closes the proximal end.

38. The ostomy component sealing system of claim 37 wherein the housing is attached to a pouch deployment prevention element which at least partially covers the collapsed collection bag and the closed proximal end.

39. The ostomy component sealing system of claim 37 wherein the housing comprises a cavity sized to hold a filter, and within the cavity there is a filter for filtering gasses flowing from the stoma.

41. The ostomy component sealing system according to claim 32, wherein the housing and the at least one element of the sealing mechanism element do not press on the stoma.

40. (canceled)

42-46. -46. (canceled)

47. A method of sealing a stoma in a subject'"'"'s body comprising:

attaching an ostomy wafer over the stoma; and

fitting onto said ostomy wafer a cap comprising a collapsed pouch, a deployment prevention element and a gas filter, without applying direct force to the stoma.
