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.
Claims15
An ostomy coupling assembly for fastening an adhesive wafer to an ostomy appliance, the ostomy appliance having an entrance aperture, and 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, the coupling assembly comprising:
- a limited motion connection permanently attached to the adhesive wafer and to 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, wherein the fixation coupling is permanently attached to the limited motion connection and includes a closed loop shape and a fixation coupling aperture;
- wherein the adhesive wafer includes a closed loop shape and a wafer aperture, the wafer aperture aligned with the fixation coupling aperture in the operative position of the limited motion connection.

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 defining a wafer aperture;
- and
- a coupling assembly for coupling the adhesive wafer to the appliance device, the coupling assembly comprising:
- a limited motion connection permanently attached to the adhesive wafer and to 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 permanently attached to the limited motion connection, the fixation coupling including a closed loop shape and a fixation coupling aperture, the fixation coupling for fixing the adhesive wafer and the appliance when in the operative position, wherein the wafer aperture and the fixation coupling aperture are aligned in the operative position of the limited motion connection.
4 more elements
A method comprising:
- (a) providing an ostomy appliance that comprises:
- 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, wherein the adhesive wafer includes a closed loop shape and a wafer aperture;
- a captive connection permanently joining the adhesive wafer captively to the appliance device in a manner permitting relative displacement between the entrance aperture of the appliance device, and substantially the entire adhesive wafer, and the captive connection defining a range of captive movement between the appliance device 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, and
- a fixation coupling permanently attached to the captive connection, the fixation coupling for fixing the adhesive wafer with respect to the entrance aperture when in the operative position, the fixation coupling including a closed loop shape and a fixation coupling aperture;
- wherein the method further comprises:
- (b) while the adhesive wafer is in said access position with respect to the entrance aperture, accessing at least the non-body-facing side of the adhesive wafer to adapt the adaptable region of the adhesive wafer to suit a stoma;
- (c) moving the adhesive wafer to the operative position with respect to the entrance aperture;
- and
- (d) securing the adhesive wafer in the operative position by the means of the fixation coupling by aligning the fixation coupling aperture with the wafer coupling aperture.
