Abstract

Ostomy ports with self closing for prevention of undesired waste leakage which changing bags or covering and uncovering of a port. A valve may be automatically activated by uncovering of the port. Optionally or alternatively, a valve may be automatically opened by covering of the port.

Claims

1. An ostomy port comprising a waste channel and a valve for selectively blocking and unblocking said waste channel, wherein said valve is configured to be activated to change a state by one or both of the covering or uncovering of said channel;

and

wherein said valve is designed to open away from a body when a force exerted in a proximal direction by waste content in said waste channel is higher than a safety threshold.

2. The ostomy port according to claim 1, wherein said valve comprises a shutter valve which is opened by axial force along said channel in a direction towards the body.

3. The ostomy port according to claim 2, wherein said valve comprises a plurality of flaps.

4. The ostomy port according to claim 1, wherein said valve comprises an expandable element.

5. The ostomy port according to claim 4, wherein said port includes one or both of a reservoir of fluid and a pump for causing inflation of a chamber associated with said expandable element.

6. The ostomy port according to claim 1, wherein said valve is configured to automatically block said channel when at least one of one of a cover and a bag on said channel is removed.

7. The ostomy port according to claim 6, wherein said at least one of a cover and a bag includes a tube which, when inserted into said channel, opens said valve and, when removed form said channel, allows said valve to self-close.

8. The port according to claim 1, wherein said valve is automatically activated to unblock said channel when said channel is covered by a suitable cover or bag.

9. The ostomy port according to claim 1, comprising a manual actuator for at least one of opening and closing said valve.

10. The ostomy port according to claim 1, wherein said valve is designed to resist a force exerted in a proximal direction by waste content in said waste channel.

11. The port according to claim 1, wherein said threshold is between 70 and 200 mmHg

28. The ostomy port according to claim 2, wherein said valve comprises an expandable element.

29. The ostomy port according to claim 3, wherein said valve comprises an expandable element.

30. The ostomy port according to claim 2, wherein said port includes one or both of a reservoir of fluid and a pump for causing inflation of a chamber associated with said expandable element.

31. The ostomy port according to claim 3, wherein said port includes one or both of a reservoir of fluid and a pump for causing inflation of a chamber associated with said expandable element.

32. The ostomy port according to claim 4, wherein said port includes one or both of a reservoir of fluid and a pump for causing inflation of a chamber associated with said expandable element.

33. The port according to claim 2, wherein said valve is automatically activated to unblock said channel when said channel is covered by a suitable cover or bag.

34. The port according to claim 3, wherein said valve is automatically activated to unblock said channel when said channel is covered by a suitable cover or bag.

35. The port according to claim 4, wherein said valve is automatically activated to unblock said channel when said channel is covered by a suitable cover or bag.

36. The port according to claim 5, wherein said valve is automatically activated to unblock said channel when said channel is covered by a suitable cover or bag.

37. The port according to claim 6, wherein said valve is automatically activated to unblock said channel when said channel is covered by a suitable cover or bag.

12. The method for regulating waste content flow through a waste channel in an ostomy port comprising:

(a) closing a valve to block said channel; and

(b) uncovering a proximal opening of said channel wherein said valve is designed to open away from a body when a force exerted in a proximal direction by waste content in said waste channel is higher than a safety threshold.

13. The method according to claim 12, wherein said closing a valve comprises automatically closing said valve by said uncovering.

14. The method according to claim 13, wherein said port has a cover including an elongate element which maintains said valve in an open configuration when inserted in said channel, and wherein said uncovering retracts said elongate element and allows said valve to close.

15. The method according to claim 14, comprising attaching a bag or a cover to said port, said attaching automatically opening said valve.

16. The method according to claim 12, comprising manually closing said valve.

17. The method according to claim 12, comprising irrigating said waste channel.

18. An ostomy port having a waste channel, comprising:

an inflatable section inside said waste channel, said section being inflatable to a degree sufficient to block said channel and deflatable to a degree whereby it does not block or interfere with flow in said channel; and

an integral inflator configured for selectively inflating said inflatable section to said blocking state wherein said port includes a reservoir for holding inflation fluid for said inflatable section.

19. The port according to claim 18, comprising a stomal cover and wherein said inflator is provided in or on said stomal cover.

20. The port according to claim 18 including a check valve for regulating pressure in said inflatable section.

21. The port according to claim 20, wherein said check valve is suitable for deflation of said inflatable section.

22. The port according to claim 18, wherein said inflator comprises an air pump.

23. The port according to claim 18, comprising a deflation valve.

24. The port according to claim 18, wherein said inflator is electrically operated and activated by one or both of covering and uncovering of said port, using a covering or uncovering sensing circuit.

25. The port according to claim 18, including an indicator indicating one or both of when said channel is blocked and when said channel is open.

26. The port according to claim 25, wherein said indicator is a visual or acoustic display electrically activated by a sensing element which senses a state of said valve.

27. The port according 18, wherein said inflator is electrically operated and includes a battery for powering said electrically operated inflator.
