Abstract

A low profile ostomy device includes an ostomy bag with an opening, a first coupling member attached to the ostomy bag at the opening, and a second coupling member for attachment to a user'"'"'s body. The first and second coupling members are engaged by the joining of an engaging element on each of the members, the engagement providing a tight mechanical seal between the members within the ostomy bag.

Claims

1. A low profile ostomy device which comprises:

(a) an ostomy bag provided with a stoma-encircling opening through the side thereof;

(b) a first coupling member comprising a flat ring portion attached to the ostomy bag through the opening and having an aperture substantially of the same size as and coincident with the ostomy bag opening, said ring having a first engaging element in the form of an annular channel having two sides and a bottom, the bottom of the channel having a rib extending upward within the channel;

said first engaging means extending into the ostomy bag; and

(c) a second coupling member comprising means for attachment to a user,s body, said second member having a second engaging element for engagement with the first engaging element, said second member having an aperture of substantially the same size as the ostomy bag opening, said second engaging element comprising an annular flange having a central groove therein which mates with said rib to provide a seal between the first and second engaging means.

2. The ostomy device according to claim 1 wherein the flange is formed of a flexible, resilient material and the rib is slightly wider than the groove in the second engaging element to thereby force the flange of the second engaging element against the channel sides of the first engaging element when the first and second engaging elements are engaged.

3. The ostomy device according to claim 2 wherein the channel has an inner wall with at least one protrusion therefrom, and the flange has at least one protrusion which interlocks with the wall protrusion when the first and second engaging elements are engaged.

4. The ostomy device according to claim 1 wherein the first coupling member is heat sealed to the ostomy bag.

5. The ostomy device according to claim 1 wherein the ring portion and the first engaging element of the first coupling member are integral.

6. The ostomy device according to claim 1 wherein the ring portion of the first coupling member comprises at least one radially extending tab adapted to be gripped by the user.

7. The ostomy device according to claim 1 wherein the attaching means of the second coupling member comprises an adhesive.

8. The ostomy device according to claim 1 wherein the first and second coupling members are each polyethylene.

9. The ostomy device according to claim 7 wherein the second coupling member comprises a flat ring having said flange integral therewith secured to a suitable material which on the body adhering portion thereof has a layer of adhesive.
