Abstract

An ostomy body side member with a sealing member is provided. The sealing member has a fixed base member defining an opening having a first diameter and a resilient sealing element comprising a stoma receiving orifice defining an inner boundary. The inner boundary of the stoma receiving orifice has a second diameter that is smaller than the first diameter of the frame. The sealing member is also provided with at least one adjustment member coupled between the fixed base member and the resilient sealing element. Furthermore, an alignment member for adjusting the tension of the at least one adjustment member is provided thereby allowing the diametrical dimension of the stoma sealing orifice to be adjusted from a first diameter to a second diameter.

Claims

1. An ostomy body side member having a sealing member where the sealing member comprises

a fixed base member defining an opening having a first diameter,

a resilient sealing element comprising a stoma receiving orifice defining an inner boundary where the inner boundary of the stoma receiving orifice has a second diameter that is smaller than the first diameter of the frame,

at least one adjustment member coupled between the fixed base member and the resilient sealing element, and

an alignment member for adjusting the tension of the at least one adjustment member so that the diametrical dimension of the stoma sealing orifice may be adjusted from a first diameter to a second diameter.

2. An ostomy body side member according to claim 1, wherein the first diameter of the stoma sealing orifice is larger than the second diameter of the stoma sealing orifice.

3. An ostomy body side member according to claim 1, wherein the first diameter of the stoma sealing orifice is smaller than the second diameter of the stoma sealing orifice.

4. An ostomy body side member according to claim 1, wherein the at least one adjustment member is adjustably coupled between the fixed base member and the resilient sealing element so that the tension of the adjustment member may be varied.

5. An ostomy body side member according to claim 1, wherein the member comprises locking means for fixing the position of the adjustment member relative to the base member.

6. An ostomy body side member according to claim 1, wherein there are two or more adjustment members coupled between the fixed base member and the resilient sealing element.

7. An ostomy body side member according to claim 6, wherein the two or more adjustment members are arranged substantially at equal radial distances from each other around the stoma sealing orifice of the resilient sealing element.

8. An ostomy body side member according to claim 1, wherein the fixed base member and the alignment member are in the form of a first ring and a second ring.

9. An ostomy body side member according to claim 8, wherein the second ring or the fixed base member is arranged to rotate relative to the first ring or the alignment member.

10. An ostomy body side member according to claim 1, wherein the fixed base member and the alignment member are arranged having a ratchet enabling click-wise rotation of the alignment member relative to the fixed base member.

11. An ostomy body side member according to claim 1, wherein the resilient sealing element is an elastomer membrane, sheet or tube.

12. An ostomy body side member according to claim 1, wherein the resilient sealing element is a silicone, rubber, thermoplastic elastomer, a Dow Corning 30 Shore A silicone type or any suitable elastomeric material.
