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:

a housing having a proximal end and a distal end with a cavity, said distal end adapted for coupling to an ostomy wafer, and said distal end being in fluid communication with said proximal end;

a sealing element accommodated within said cavity;

a lid removably attached to said proximal end; and

a collapsed pouch deployable into a waste collection mode through the removal of said lid, said removal actuatable manually or automatically by the pressure buildup inside said ostomy appliance.

2. The ostomy appliance of claim 1, wherein said sealing element is adapted for sealing an interface between said ostomy wafer and said housing.

3. The ostomy appliance of claim 1, wherein said sealing element comprises compressible material.

4. The ostomy appliance of claim 1, wherein said sealing element is a compressible foam element.

5. The ostomy appliance of claim 1, wherein said sealing element comprises a waste absorbing material.

6. The ostomy appliance of claim 5, wherein said sealing element is capable of absorbing up to 30 mL of liquid waste.

7. The ostomy appliance of claim 1, wherein said sealing element has an annular shape.

8. The ostomy appliance of claim 1, wherein said sealing element is made of a distending material capable of absorbing liquid waste and expanding within said cavity.

9. The ostomy appliance of claim 1, wherein said distal end comprises a snap-fit attachment mechanism for attachment to said wafer.

10. The ostomy appliance of claim 1 comprising a gas flow path having a filter for filtering gases flowing from the stoma.

11. The ostomy appliance of claim 10, wherein said filter comprises a deodorizing gas filter.

12. The ostomy appliance of claim 5, wherein said sealing element is permeable to gas.

13. The ostomy appliance of claim 1, wherein said housing comprises an opening for releasing gas flowing from a stoma without deploying said pouch.

14. The ostomy appliance of claim 13, wherein said opening for releasing gas is fitted with a valve.

15. The ostomy appliance of claim 14, wherein said valve is selectively openable by a user.

16. The ostomy appliance of claim 1, wherein said lid is configured to bulge outwards or stiffen in response to a pressure from waste content or flatus gas inside said housing, wherein the bulging outwards or stiffening of said lid is sensible by a user and indicates the need for deployment of said collapsed pouch to release waste content or gas.

17. The ostomy appliance of claim 1, wherein removal of said lid is automatically actuatable at colonic pressure of greater than or equal to 80 mmHg.

18. The ostomy appliance of claim 1, wherein said pouch is disposed externally to said housing.

19. The ostomy appliance of claim 1 adapted to be physically isolated from the stoma to prevent tissue damage.

20. A method of using an ostomy appliance attached to an ostomy wafer surrounding a stoma of a user, wherein said ostomy appliance comprises:

a housing having a proximal end and a distal end with a cavity, said distal end adapted for coupling to said ostomy wafer, and said distal end being in fluid communication with said proximal end;

a sealing element accommodated within said cavity;

a lid removably attached to said proximal end; and

a collapsed pouch deployable into a waste collection mode through the removal of said lid, said removal actuatable manually or automatically by the pressure buildup inside said ostomy appliance,

said method comprising manually removing said lid to deploy said pouch into said waste collection mode to eliminate waste through said stoma.

21. The method of claim 20, further comprising removing the ostomy appliance after elimination of waste and replacing it with an unused ostomy appliance.

22. The method of claim 20, wherein said lid is configured to bulge outwards or stiffen in response to a pressure from waste content or flatus gas inside said housing, and said method further comprises sensing said bulging or stiffening prior to said removing.

23. The method of claim 20, further comprising opening a valve to release gas without deploying said collapsed pouch, wherein said ostomy appliance further comprises an opening for releasing gas flowing from a stoma without deploying said pouch, and said opening is fitted with said valve, which is selectively openable by said user.

24. The method of claim 20, wherein removal of said lid is automatically actuatable at colonic pressure of greater than or equal to 80 mmHg.

25. An ostomy appliance comprising:

a housing having a proximal end and a distal end with a cavity, said distal end adapted for coupling to an ostomy wafer through a snap-fit arrangement, and said distal end being in fluid communication with said proximal end, wherein said housing comprises an opening fitted with a valve selectively openable by a user for releasing gas flowing from a stoma;

an annular compressible foam sealing element accommodated within said cavity, said sealing element being permeable to gas;

a lid removably attached to said proximal end, said lid configured to bulge outwards or stiffen in response to a pressure from waste content or flatus gas inside said housing;

and

a collapsed pouch disposed externally to said housing and deployable into a waste collection mode through the removal of said lid, wherein said removal is actuatable manually or automatically by the pressure buildup inside said ostomy appliance.

26. The ostomy appliance of claim 25, further comprising a gas flow path having a deodorizing filter for filtering gases flowing from the stoma.

27. The ostomy appliance of claim 25, wherein said sealing element is made of a distending material capable of absorbing liquid waste and expanding within said cavity.
