Abstract

An ostomy appliance having:—

• • first and fourth walls connected to each other at or near their peripheries, the first wall having a stoma-receiving opening;
  • second and third walls positioned in between the first and fourth walls, the second wall being connected to one or more of the first, third and/or fourth walls, and the third wall being connected to one or more of the first, second and/or fourth walls;
  • a waste collecting cavity defined between either the first and second walls or first and fourth walls;
  • a second cavity defined between the second and third walls;
  • a third cavity defined between the third and fourth walls;
  • a first gas flow path in the second wall to permit waste gases to pass from the waste collecting cavity to the second cavity;
  • a second gas flow path in the third wall to permit waste gases to pass from the second cavity to the third cavity; and
  • a third gas flow path in the fourth wall to permit waste gases to escape from the third cavity,
  • wherein the second and third walls are connected to each other so as to define a liquid flow path which permits liquid within the second cavity to flow into the waste collecting cavity.

Claims

1. An ostomy appliance having:

—

first and fourth walls connected to each other at or near their peripheries, the first wall having a stoma-receiving opening;

second and third walls positioned in between the first and fourth walls, the second wall being connected to one or more of the first, third and/or fourth walls, and the third wall being connected to one or more of the first, second and/or fourth walls;

a waste collecting cavity defined between either the first and second walls or first and fourth walls;

a second cavity defined between the second and third walls;

a third cavity defined between the third and fourth walls;

a first gas flow path in the second wall to permit waste gases to pass from the waste collecting cavity to the second cavity;

a second gas flow path in the third wall to permit waste gases to pass from the second cavity to the third cavity, and

a third gas flow path in the fourth wall to permit waste gases to escape from the third cavity,

wherein the second and third walls are connected to each other so as to define a liquid flow path which permits liquid within the second cavity to flow into the waste collecting cavity.

2. An appliance according to claim 1 wherein the liquid flow path permits liquid within the second cavity to flow into the waste collecting cavity under gravity.

3. An appliance according to claim 1 wherein the second and third walls are connected to each other and wherein the liquid flow path is provided as a break, gap or opening in said connection.

4. An appliance according to claim 1 wherein the first gas flow path is an aperture or slit in the second wall.

5. An appliance according to claim 1 wherein the second gas flow path is an aperture or slit in the third wall.

6. An appliance according to claim 1 wherein the third gas flow path is an aperture or slit in the fourth wall.

7. An appliance according to claim 4 wherein the aperture or slit is covered by a gas filter.

8. An appliance according to claim 1 wherein the second and/or third walls is/are smaller in surface area than the first and fourth walls.

9. An appliance according to claim 1 wherein the second and/or third walls is/are positioned towards a top of the appliance.

10. An appliance according to claim 1 wherein the second and/or third walls is/are positioned generally opposite the stoma receiving opening in the first wall.

11. An appliance according to claim 1 wherein the appliance includes a closable outlet which communicates with the waste collecting cavity for emptying its contents.

12. An appliance according to claim 1 wherein there are two or more liquid flow paths.

13. An appliance according to claim 3 wherein there are two breaks, gaps or openings in said connection of the second and third walls.

14. An appliance according to claim 11, wherein the liquid flow path(s) is/are provided in the connection of the peripheral edges of the second and third walls which edges generally face downwardly towards the outlet.

15. An appliance according to claim 1 wherein the liquid flow path is configured to permit liquid to pass only in the direction of the second cavity to the waste collecting cavity.

16. An appliance according to claim 1 wherein the liquid flow path is a one-way valve.

17. An appliance according to claim 1 wherein the fourth wall includes first and second portions which are connected to each other.

18. An appliance according to claim 1 wherein the first and second portions of the fourth wall and the second wall are connected to each other.

19. An ostomy appliance having:

—

first and fourth walls connected to each other at or near their peripheries, the first wall having a stoma-receiving opening;

a second wall positioned in between the first and fourth walls, the second wall being connected to one or more of the first and/or fourth walls;

a waste collecting cavity defined between either the first and second walls or first and fourth walls;

a second cavity defined between the second and fourth walls;

a first gas flow path in the second wall to permit waste gases to pass from the waste collecting cavity to the second cavity; and

a second gas flow path in the fourth wall to permit waste gases to escape from the second cavity;

wherein the second and fourth walls are connected to each other so as to define a liquid flow path which permits liquid within the second cavity to flow into the waste collecting cavity.
