Abstract

A coupling assembly for fastening an adhesive wafer to an ostomy appliance device, the coupling assembly including a captive connection between the adhesive wafer and ostomy appliance that permits captive relative displacement between the entire adhesive wafer and the entrance aperture of the appliance, to facilitate access to the wafer from the non-body-contacting side. The coupling assembly further comprises a fixation coupling for fixing the adhesive wafer in the operative position.

Claims

a limited motion connection between the adhesive wafer and the ostomy appliance that permits relative displacement between (i) substantially the entire adhesive wafer and (ii) the entrance aperture of the ostomy appliance, the limited motion connection guiding said relative displacement along a limited motion path or locus, between (a) an operative position in which the adhesive wafer is superposed around the entrance aperture of the ostomy appliance, and the adaptable region of the adhesive wafer is shrouded by the ostomy appliance on the non-body-facing side, and (b) an access position providing access to the adaptable region from the non-body-facing side; and

a fixation coupling for fixing the adhesive wafer and the ostomy appliance when in the operative position.

2. The ostomy coupling assembly of claim 1, wherein the limited motion connection permanently joins the adhesive wafer to the ostomy appliance.

3. The ostomy coupling assembly of claim 1, wherein the limited motion connection comprises a first attachment portion for attaching to a pouch, a second attachment portion for attaching to the adhesive wafer, and a movable joint portion between the first and second attachment portions.

4. The ostomy coupling assembly of claim 3, wherein at least one of the first and second attachment portions has a closed loop shape.

5. The ostomy coupling assembly according to claim 3, wherein the first and second attachment portions and the moveable joint portion are integrally formed as a unitary piece.

6. The ostomy coupling assembly according to claim 3, wherein the first and second attachment portions are separate pieces movably connected at the joint portion.

7. The ostomy coupling assembly according to claim 3, wherein the first and second attachment portions are made of plastics film.

8. The ostomy coupling assembly according to claim 1, wherein the limited motion connection defines a locus of movement about an axis selected from:

generally parallel to a plane of the wafer;

or generally perpendicular to a plane of the wafer.

9. The ostomy coupling assembly according to claim 1, wherein the fixation coupling is selected from:

a mechanical coupling;

an adhesive coupling.

10. The ostomy coupling assembly according to claim 1, wherein at least a portion of the fixation coupling is integral with at least a portion of the limited motion connection.

11. The ostomy coupling assembly according to claim 1, wherein the ostomy coupling is a unitary device.

12. An ostomy appliance comprising:

an appliance device having an entrance aperture for communicating with a stoma;

an adhesive wafer for mounting on the body around a stoma, the adhesive wafer including a body-facing side for contacting a user'"'"'s skin, a non-body-facing side opposite the body-facing side, and an adaptable region adaptable to fit around a stoma; and

a coupling assembly for coupling the adhesive wafer to the appliance device, the coupling assembly comprising;

a limited motion connection between the adhesive wafer and the appliance that permits relative displacement between (i) substantially the entire adhesive wafer and (ii) the entrance aperture of the appliance, the limited motion connection guiding said relative displacement along a limited motion locus, between (a) an operative position in which the adhesive wafer is superposed around the entrance aperture of the appliance, and the adaptable region of the adhesive wafer is shrouded by the appliance on the non-body-facing side, and (b) an access position providing access to the adaptable region from the non-body-facing side; and

a fixation coupling for fixing the adhesive wafer and the appliance when in the operative position.

13. The ostomy appliance of claim 12, wherein the appliance is selected from:

a one-piece appliance in which the coupling assembly permanently attaches the adhesive wafer to the appliance device;

a two-piece appliance in which the coupling assembly releasably attaches the adhesive wafer to the appliance device.

14. A one-piece ostomy appliance comprising:

an appliance device having an entrance aperture for communicating with a stoma;

an adhesive wafer for mounting on the body around a stoma, the adhesive wafer including a body-facing side for contacting a user'"'"'s skin, a non-body-facing side opposite the body-facing side, and an adaptable region adaptable to fit around a stoma; and

a captive connection permanently joining the adhesive wafer captively to a pouch in a manner permitting relative displacement between the entrance aperture of the pouch, and substantially the entire adhesive wafer, the captive connection defining a range of captive movement between the pouch and the adhesive wafer, the captive range of movement including;

(i) a superposed operative position in which the adhesive wafer is superposed around the entrance aperture, and the adaptable portion of the adhesive wafer is shrouded on the non-body-facing side by the appliance; and

(ii) an access position providing access from the non-body-facing side to the adaptable portion of the adhesive wafer.

15. The one-piece ostomy appliance of claim 14, wherein the captive connection is a limited motion connection for guiding relative displacement between the adhesive wafer and the entrance aperture.

16. The one-piece ostomy appliance of claim 14, wherein captive connection comprises a first attachment portion attached to the pouch, a second attachment portion attached to the adhesive wafer, and a movable joint portion between the first and second attachment portions.
