7. The cap according to claim 1 , wherein the capsule has an annular fastener attachable to a snap fitting arrangement.
8. The cap according to claim 7 , wherein said cap is shaped to extend less than 1 cm proximally from said snap-fitting arrangement when attached thereto.
9. The cap according to claim 1 , further including a gas filtering mechanism.
10. The cap according to claim 1 , wherein said predetermined value is at or above 80 mmHg.
11. The cap according to claim 1 , wherein said predetermined value is at or above 100 mmHg.
12. The cap according to claim 1 , wherein said predetermined value is at or above 150 mmHg.
13. The cap according to claim 1 , wherein said predetermined value comprises a combination of pressure and time selected from among the group consisting of:
a pressure of at least 60 mmHg applied for at least 2 minutes,
a pressure of at least 100 mmHg applied for at least 30 seconds, and
immediate ejection of said cap-covering upon application of a pressure of at least 150 mmHg.
14. The cap according to claim 1 , wherein said bag has a volume when collapsed of less than 10 cc and when full of at least 300 cc.
15. The cap according to claim 1 , wherein said cap-covering comprises a pressure indication mechanism.
16. The cap according to claim 15 , wherein said pressure indication mechanism comprises a flexible portion of said cap-covering, which protrudes outwards in response to said intestinal pressure.
17. The cap according to claim 16 , wherein said intestinal pressure is 50 mmHg or higher.
18. The cap according to claim 16 , wherein said flexible portion has a thickness in the range from 0.2-2 mm.
19. The cap according to claim 1 , wherein said bag is external to said capsule in a cavity between said cap-covering and said capsule.
20. A method of preventing leakage of waste content from a stoma, said method comprising:
fitting into position the cap of claim 1 ; and
deploying said bag manually or automatically; said deploying manually comprising manually detaching said cap-covering from said capsule, and said deploying automatically comprising said bag detaching said cap-covering from said capsule under an intestinal pressure that is higher than said predetermined value.
21. The method of claim 20 , wherein said intestinal pressure is at or above 80 mmHg.
22. The method of claim 20 , wherein said intestinal pressure is at or above 100 mmHg.
23. The method of claim 20 , wherein said intestinal pressure is at or above 150 mmHg.
24. The method of claim 20 , wherein said predetermined value is a combination of said intestinal pressure and a period of application of said intestinal pressure, said combination selected from the group consisting of:
application of said intestinal pressure of at least 60 mmHg for at least 2 minutes,
application of said intestinal pressure of at least 100 mmHg for at least 30 seconds, and
application of said intestinal pressure of at least 150 mmHg leading to said deploying automatically immediately.
25. The method of claim 20 , wherein said cap-covering is attached to said capsule separately from said bag.
26. The method of claim 20 , wherein said cap-covering includes a pullable element for manual removal.
27. The method of claim 20 , wherein said cap-covering is attached at a rim located at a proximal side of said capsule.
28. The method of claim 20 , wherein said bag has a volume when collapsed of less than 10 cc and when full of at least 300 cc.
29. The method of claim 20 , wherein said bag is external to said capsule in a cavity between said cap-covering and said capsule.
30. The method of claim 20 , wherein said cap-covering comprises a pressure indication mechanism.
31. The method of to claim 30 , wherein said pressure indication mechanism comprises a flexible portion of said cap-covering, which protrudes outwards in response to said intestinal pressure.
32. The method of claim 31 , wherein said intestinal pressure is 50 mmHg or higher.
33. The method of claim 31 , wherein said flexible portion has a thickness in the range of from 0.2-2 mm.
34. The method of claim 20 , wherein said cap further includes a gas filtering mechanism.
35. The method of claim 20 , wherein the capsule has an annular fastener attachable to a snap fitting arrangement, and said fitting comprises attaching said fastener to said arrangement.
36. An ostomy cap comprising:
a capsule having an annular fastener attachable to a snap-fitting arrangement;
an elastomeric cap-covering comprising a pressure indication mechanism, said cap-covering removably attached at a rim at a proximal side of said capsule; and
a bag external to said capsule in a cavity between said cap-covering and said capsule;
wherein said cap-covering is detachable from said capsule by deployment of said bag at an intestinal pressure at or above a predetermined value, wherein the interior of said bag is not fluidly coupled to said cap-covering when the bag is deployed and undeployed.
37. The cap according to claim 36 , wherein said predetermined value is at or above 50 mmHg.
