Abstract

An ostomy appliance including an adhesive barrier member having a hole for receiving a stoma, ureter, or catheter, an outer receiving member or bag releasably attached to the adhesive barrier member, and a disposable inner bag liner releasably attached to the adhesive barrier member. A single base coupling ring is attached to the barrier member and includes a first coupling area on an inner surface thereof, relative to the hole, and a second coupling on an outer surface thereof. The inner bag, which is coupled to the barrier member using an inner bag coupling ring, is coupled to the barrier member at the first coupling area and the outer receiving member is coupled to the barrier member at the second coupling area, such that both the inner bag and outer receiving member are mounted on the same single barrier member ring.

Claims

1. An ostomy appliance comprising:

an adhesive barrier member having a hole for receiving a stoma, ureter, or catheter, and a barrier wafer to be attached to the wearer'"'"'s abdomen, back, or chest;

an outer receiving member having a hole for receiving wastes exiting the stoma, ureter or catheter;

a disposable inner bag having a hole for receiving wastes exiting the stoma, ureter or catheter, said inner bag fitting within said outer receiving member;

an inner bag coupling ring separate from said inner bag so as to be separately exchangeable; and

a single base coupling ring attached to said barrier member and surrounding said barrier member hole, said single base coupling ring having a first coupling area on an inner surface thereof relative to said hole and a second coupling area on an outer surface thereof, said inner bag and inner bag coupling ring being releasably coupled to said barrier member at said first coupling area and said outer receiving member being releasably coupled to said barrier member at said second coupling area.

2. An ostomy appliance as claimed in claim 1 wherein said inner bag coupling ring and said single base coupling ring are concentric.

3. An ostomy appliance as claimed in claim 1 wherein the first coupling area is in the form of a groove in the inner surface of the base coupling ring.

4. An ostomy appliance as claimed in claim 1 wherein the first coupling area is in the form of a recess at a lower inner edge of the base coupling ring.

5. An ostomy appliance as claimed in claim 4 wherein said inner bag coupling ring has an outwardly extending rib for engaging with said recess on the lower inner edge of said base coupling ring.

6. An ostomy appliance as claimed in claim 5 wherein said inner bag coupling ring further includes an upwardly and outwardly protruding member for engaging an upper rim of said base coupling ring to prevent the inner bag coupling ring from being pushed in too far when mounted to said barrier member.

7. An ostomy appliance as claimed in claim 1 wherein the exchangeable inner bag coupling ring has an inner diameter d₁ and an outer diameter d₂ and the inner bag when flattened has an open end having a width W, said inner bag when in an open state having a generally circular opening with a diameter Dl, said diameter Dl being less than said outer diameter d_2.

8. An ostomy appliance as claimed in claim 7 wherein the width W is greater than said outer diameter d₂.

9. An ostomy appliance comprising:

a barrier member having a hole for receiving a stoma, ureter, or catheter;

an outer receiving member having a hole for receiving wastes exiting the stoma, ureter or catheter;

a disposable inner bag having a hole for receiving wastes exiting the stoma, ureter or catheter;

an inner bag coupling ring for coupling said inner bag to said barrier member, said inner bag coupling ring being separate from said inner bag so as to be separately exchangeable; and

a single base coupling ring attached to said barrier member and surrounding said barrier member hole, said single base coupling ring having a first coupling area on an inner surface thereof relative to said hole and a second coupling area on an outer surface thereof, said inner bag coupling ring being releasably coupled to said barrier member at said first coupling area and said outer receiving member being releasably coupled to said barrier member at said second coupling area, an outer diameter of said inner bag coupling ring being smaller than an inner diameter of said base coupling ring.

10. An ostomy appliance as claimed in claim 9 wherein said inner bag coupling ring and said single base coupling ring are concentric.

11. An ostomy appliance as claimed in claim 9 wherein the first coupling area is in the form of a groove in the inner surface of the base coupling ring.

12. An ostomy appliance as claimed in claim 9 wherein the first coupling area is in the form of a recess at a lower inner edge of the base coupling ring.

13. An ostomy appliance as claimed in claim 12 wherein said inner bag coupling ring has an outwardly extending rib for engaging with said recess on the lower inner edge of said base coupling ring.

14. An ostomy appliance as claimed in claim 13 wherein said inner bag coupling ring further includes an upwardly and outwardly protruding member for engaging an upper rim of said base coupling ring to prevent the inner bag coupling ring from being pushed in too far when mounted to said barrier member.

15. An ostomy appliance as claimed in claim 9 wherein the exchangeable inner bag coupling ring has an inner diameter d₁ and an outer diameter d₂ and the inner bag when flattened has an open end having a width W, said inner bag when in an open state having a generally circular opening with a diameter Dl, said diameter Dl being less than said outer diameter d₂.

16. An ostomy appliance as claimed in claim 15 wherein the width W is greater than said outer diameter d₂.
