Abstract

A stoma closure that includes a conformable portion for conforming to an individual'"'"'s stoma. The conformable portion includes a sack containing particles. The conformable portion may include a gel that may be loose or be at least partly contained in a sack. The conformable portion may include foam. The conformable portion may be configured to permit venting of flatus, while obstructing the passage of liquid/solid stool.

Claims

1. A stoma closure comprising:

a. a mounting member for attachment directly or indirectly to skin around the stoma,

b. a flexible chamber secured to said mounting member,

c. a plurality of particles contained inside the flexible chamber, said flexible chamber and said particles being conformable to the stoma so as to block the passing of stool from the stoma, wherein said particles are configured to freely move inside of said flexible chamber, and wherein said flexible chamber confines said particles entirely inside said flexible chamber,

d. a deodorizing filter secured to said mounting member for filtering flatus venting from the stoma through or around said flexible chamber and through said mounting member.

2. The stoma closure according to claim 1, wherein the flexible chamber is impermeable to liquid stool.

3. The stoma closure according to claim 1, wherein the flexible chamber is porous.

4. The stoma closure according to claim 1, wherein the flexible chamber comprises a mesh material.

5. The stoma closure according to claim 1, wherein the particles are in a size range of from about 0.1 mm to about 10 mm.

6. The stoma closure according to claim 1, wherein the particles are about the same size as one another.

7. The stoma closure according to claim 1, wherein the particles have generally the same shape as one another.

8. The stoma closure according to claim 1, wherein at least some of the particles are of generally different shape from other particles.

9. The stoma closure according to claim 1, wherein at least some of the particles are of generally different size from other particles.

10. The stoma closure according to claim 1, wherein the chamber is pressurizable.

11. The stoma closure according to claim 1, wherein the chamber is depressurizable.

12. The stoma closure according to claim 1, wherein the chamber comprises elastic material.

13. The stoma closure according to claim 1, wherein at least some of the particles comprise malodor counteractant.

14. The stoma closure according to claim 1, wherein at least some of the particles are expandable when wet.

15. The stoma closure according to claim 1, wherein at least some of the particles have a surface characteristic, or a surface treatment, that is hydrophilic.

16. The stoma closure according to claim 1, wherein at least some of the particles have a surface characteristic, or a surface treatment, that is hydrophobic.

17. The stoma closure according to claim 1, wherein at least some of the particles have a surface characteristic or surface treatment that enhances their performance for controlling the release of effluent from a stoma.

18. The stoma closure of claim 1, wherein said chamber comprises a distal end configured to be inserted inside of said stoma and a proximal end comprising a flared shape configured to engage an exteriorized surface of said stoma.

19. The stoma closure of claim 1, further comprising a belt configured to engage with said mounting member and secure said mounting member to the skin of a patient.
