A multi-layer reduced pressure delivery apparatus is provided for applying reduced pressure tissue treatment to a tissue site. The multi-layer apparatus includes a tissue contact layer, a release layer, and a manifold layer. The tissue contact layer includes a scaffold adapted to contact the tissue site, the release layer includes a hydrogel-forming material and a plurality of flow channels, and the manifold layer includes a distribution manifold. The release layer is positioned between the tissue contact layer and the manifold layer to allow easy release of the manifold layer from the tissue contact layer following the administration of reduced pressure tissue treatment.

L'invention concerne un dispositif multicouche d'apport à pression réduite qui sert à appliquer sur un site de tissu un traitement de tissu à pression réduite. Le dispositif multicouche comprend une couche de contact de tissu, une couche antiadhésive et une couche de collecteur. La couche de contact de tissu comprend une structure conçue pour être en contact avec le site de tissu, la couche antiadhésive comprend une matière formant un hydrogel et une pluralité de canaux d'écoulement, et la couche de collecteur comprend un collecteur de distribution. La couche antiadhésive est placée entre la couche de contact de tissu et la couche de documents pour permettre de décoller facilement la couche de collecteur de la couche de contact de tissu, après l'administration du traitement de tissu à pression réduite.
