Abstract

A stoma adapter is described that is especially suited to a recessed stoma or a flush stoma. The stoma adapter effectively extends the discharge passage from the stoma, protects peristomal skin, and forms a bridge at the interface between the stoma and an ostomy appliance. The stoma adapter contains a substantially unobstructed discharge passage, at least for effluent flowing in a discharge direction. The stoma adapter includes a seal for sealing against the bowel wall. The stoma adapter has collapsing, expanding, flexible and reinforced designs.

Claims

1. A stoma adapter comprising a proximal end for insertion into a stoma and/or into a peristomal mouth surrounding a recessed stoma, and a discharge passage extending from the proximal end, the discharge passage being substantially unobstructed at least for effluent flowing in a discharge direction.

2. The stoma adapter according to claim 1, wherein the stoma adapter is selected from:

configured for a recessed stoma;

or configured for a flush stoma.

4. The stoma adapter according to claim 1, wherein the discharge passage is selected from:

configured to direct effluent away from peristomal skin or configured to bridge an interface between the stoma and an ostomy appliance.

6. The stoma adapter according to claim 1, wherein the discharge passage is open.

7. The stoma adapter according to claim 1, wherein the stoma adapter is provided in a form selected from an axial form to facilitate insertion at a stoma;

a transaxial form to facilitate insertion at a stoma;

a collapsed form to facilitate insertion at a stoma; and

a collapsible form to facilitate insertion at a stoma.

11. The stoma adapter according to claim 7, further comprising a means for changing the configuration of the stoma adapter after insertion of the stoma adapter at the stoma.

12. The stoma adapter according to claim 7, wherein the stoma adapter comprises generally flexible material and at least one bolster for reinforcing the flexible material against flexing in at least a predetermined direction with respect to the bolster.

13. The stoma adapter according to claim 12, wherein the at least one bolster is configured to reinforce the stoma adapter at least in a substantially axial direction of the stoma adapter, while permitting flexure in a transaxial direction.

24. The stoma adapter according to claim 1, wherein the stoma adapter comprises a seal disposed at, or near, the proximal end for sealing against the bowel wall.

26. The stoma adapter according to claim 24, wherein the seal is inflatable.

28. The stoma adapter according to claim 26, wherein the seal encloses a resilient material.

36. The stoma adapter according to claim 1, wherein a distal end of the stoma adapter is substantially free.

37. The stoma adapter according to claim 1, wherein a distal end of the stoma adapter is attached or attachable to at least one of the group consisting of:

peristomal skin;

an adhesive body fitment; and

ostomy appliance.

38. An adhesive body fitment for attaching an ostomy appliance to peristomal skin, the adhesive body fitment comprising a stoma adapter projecting towards the stoma for insertion into the stoma and/or into a peristomal mouth surrounding a recessed stoma, the stoma adapter comprising a discharge passage that is substantially unobstructed at least for effluent flowing in a discharge direction.

39. An ostomy appliance comprising a stoma adapter projecting towards the stoma for insertion into the stoma and/or into a peristomal mouth surrounding a recessed stoma, the stoma adapter comprising a discharge passage that is substantially unobstructed at least for effluent flowing in a discharge direction.
