An adhesive faceplate for detachable connection to an ostomy pouch is disclosed. The faceplate has an integrated convex pressure ring for promoting stomal protrusion and a so-called floating flange (i.e., coupling ring) for mechanical attachment to the mating coupling ring of an ostomy pouch. The convex pressure ring is provided with a deep annular recess behind the faceplate's coupling ring to accommodate a user's fingers during a coupling operation, thereby facilitating attachment of a pouch. The recess is also useful because it may accommodate the flexible web (which is preferably pleated to allow greater movement of the faceplate's coupling ring) when the coupling ring is immediately adjacent the remainder of the faceplate. The pressure ring includes a thin, inwardly-extending connecting portion which is heat sealed to the backing layer of the faceplate's adhesive wafer and, when that backing layer is formed of a porous material, such heat seal effectively closes the pores of the backing layer in the area of the seal.

Description d'une plaque de recouvrement adhésive permettant une connexion amovible à une poche pour stomie. La plaque de recouvrement possède un anneau de pression convexe intégré favorisant une saillie peptique ainsi que le fonctionnement d'une bride dite flottante (par ex., un anneau de raccord), afin de permettre l'attachement mécanique à l'anneau de raccord de la poche pour stomie. L'anneau de pression convexe possède un renfoncement annulaire profond derrière l'anneau de raccord de la plaque de recouvrement afin de s'adapter aux doigts de l'utilisateur durant l'opération de raccord, facilitant ainsi l'attachement de la poche. Le renfoncement est aussi utile parce qu'il peut s'adapter à une toile flexible (plissée, de préférence, pour permettre un plus grand mouvement de l'anneau de raccord de la plaque de recouvrement) lorsque l'anneau de raccord est immédiatement adjacent au reste de la plaque de recouvrement. L'anneau de pression inclut un élément de connexion mince s'étendant vers l'intérieur, qui est thermocollé à la couche dorsale de la tranche adhésive de la plaque de recouvrement. Lorsque cette couche dorsale est formée d'un matériau poreux, un tel thermocollage permet de fermer efficacement les pores de la couche dorsale dans la partie concernée.
