Ostomy appliance with moldable adhesive
View Patent ↗A body fitment for an ostomy appliance comprises an adhesive wafer including a moldable region shapable by the user. A removable release liner covering an external adhesive surface of the wafer is configured to permit molding of the moldable region by manually manipulating the adhesive through the release liner, and/or with removable segments. In an alternative form, an interior release liner is removable through the entrance aperture of the wafer, by pulling on a grip portion that protrudes through the entrance aperture. In an alternative form, an ostomy pouch includes a finger pocket in a front pouch wall, for permitting insertion of a finger tip for molding the moldable region of an adhesive wafer that is secured around a stomal aperture in a rear pouch wall.
1. A one-piece ostomy appliance comprising an adhesive body fitment permanently attached to an ostomy pouch having an effluent receiving aperture for adhesively mounting the ostomy pouch to a wearer's body, the body fitment comprising:
an adhesive wafer for adhesively contacting the wearer's body peristomally, the adhesive wafer including a moldable region shapable by the user for allowing a user to manually mold a stomal aperture in said moldable region, and the adhesive wafer including, at least in the moldable region, an adhesive body-contacting face and an adhesive non-body-contacting face opposite the body-contacting face;
an interior release liner substantially covering said non-body-contacting face of the moldable region of the adhesive wafer, the interior release liner including a grip portion extending through the stomal aperture of the moldable region to enable gripping of the grip portion by a user's finger for enabling the interior release liner to be removed from said non-body-contacting face of the adhesive wafer, to facilitate molding of the moldable region.
2. The one-piece appliance of claim 1 , wherein the stomal aperture is a starter hole within the moldable region of the adhesive wafer.
3. The one-piece appliance of claim 1 , wherein the interior liner is configured to be removable by extracting the release liner from the appliance through the stomal aperture.
4. The one-piece appliance of claim 1 , wherein the grip portion is configured to promote peeling of the interior release liner from the adhesive non-body-contacting face of the moldable region, when a pulling force is applied to the grip portion.
5. The one-piece appliance of claim 1 , wherein the grip portion includes a fold to apply the pulling force in a direction to promote peeling.
6. The one-piece appliance of claim 1 , wherein the grip portion extends from an inner or outer periphery of the interior release liner.
7. The one-piece appliance of claim 1 , wherein the interior liner and the grip portion together have a sombrero-like shape.
8. The one-piece appliance of claim 1 , wherein the interior liner comprises at least one division line dividing the release liner into one or more continuous segments that together define a shape making up the area of the release liner.
9. The one-piece appliance of claim 8 , wherein the division line comprises one or more selected from: a cut; a slit; a line of weakening; a score; a line of perforations.
10. The one-piece appliance of claim 8 , wherein the division line comprises one or more lines selected from: a spiral; a round spiral; a polygonal spiral; a split spiral with boustrophedon turns.
11. The one-piece appliance of claim 2 , further comprising an exterior release liner covering the body-contacting face of the adhesive wafer.
