Abstract

A balloon-like member is received in the bowel and inflated to seal the stoma. The member includes a thin, flexible wall defining an opening. A rigid or semi-rigid cap retains the member and closes the opening in the member wall. Skin comfortable adhesive adheres the edge of the cap to the tissue surrounding the stoma. A flexible dilation tube facilitates insertion of the member and cooperates with a pump to inflate the member. The cap is preferably removeably attached to a standard two-piece ostomy faceplate and is provided with a filter element to vent flatus.

Claims

1. An ostomy device comprising a balloon-like member adapted to be inserted into the bowel and inflated to seal the stoma, said member comprising a flexible wall defining an opening, cap means for retaining said wall and closing said opening, and means for adhering said cap means to the tissue proximate the stoma.

2. The device of claim 1 further comprising means for inflating said member.

3. The device of claim 2 wherein said cap means comprises a port, flexible tube means connected to said port, said tube means being adapted to extend into said member and comprising an inflation channel.

4. The device of claim 3 wherein said inflating means further comprises pump means adapted to be connected to said inflation channel through said port.

5. The device of claim 2 wherein said inflating means comprises a pressure relief valve.

6. The device of claim 3 wherein said tube means comprises a one-way valve.

7. The device of claim 1 wherein said adhering means comprises a faceplate and means for detachably mounting said cap means on said faceplate.

8. The device of claim 7 wherein said faceplate comprises a first engaging part defining an opening, said parts being adapted to engage, with said opening in said second engaging part aligned with the stoma.

9. The device of claim 8 wherein said detachable mounting means further comprises a member retaining part defining an opening and a waste collection receptacle having a first inlet aligned with said second engaging part opening and a wall defining a second inlet, said receptacle wall being sealed to said member retaining part with said second inlet aligned with said opening in said member retaining part.

10. The device of claim 9 further comprising a channel defined between said wall of said member and the interior wall of said receptacle and filter means operably interposed between said channel and the environment.

11. The device of claim 10 wherein said filter means is situated in said retaining part.

12. The device of claim 8 further comprising means for detachably mounting said cap means on said second engaging part.

13. The device of claim 9 wherein said member retaining part comprises a disc and wherein said disc is adapted to be received between said cap means and said second engaging part.

14. The device of claim 3 wherein said inflating means comprises a hand pump comprising a nozzle adapted to be removably connected to said tube means, in communication with said inflation channel.

15. The device of claim 1 wherein said member comprises a bulbous proximal end.

16. An ostomy device comprising a balloon-like member adapted to be received in the bowel and inflated to seal the stoma, a faceplate, means for adhering said faceplate to the tissue surrounding the stoma, said member comprising a flexible wall defining an opening, cap means for retaining said wall and closing said opening in said member, said cap means comprising an inflation port, and means for mounting said cap means on said faceplate.

17. The device of claim 16 further comprising a waste collection receptacle operably interposed between said cap means and said faceplate.

18. The device of claim 17 wherein said cap means mounting means comprises means for detachably engaging said faceplate and means for detachably mounting said cap means on said faceplate engaging means.

19. The device of claim 16 wherein said faceplate comprises a first engaging part and cap means mounting means comprises a second engaging part.

20. The device of claim 16 further comprising means for inflating said member.

21. The device of claim 20 wherein said cap means comprises flexible tube means comprising an inflation channel connected to said inflation port.

22. The device of claim 21 further comprising a one-way valve associated with said inflation channel.

23. The device of claim 17 further comprising a channel defined between said wall of said member and the interior wall of said receptacle, and filter means operably interposed between said channel and the environment.

24. The device of claim 23 wherein said cap means mounting means comprises a member retaining part to which said member wall is affixed.

25. The device of claim 24 wherein said filter means is situated in said retaining part.

26. The device of claim 20 wherein said inflating means comprises a hand pump comprising a nozzle adapted to be removably connected to said inflation port.

27. The device of claim 16 wherein said member comprises a bulbous proximal end.
