The illustrative systems, methods, and dressings for applying reduced pressure to a tissue site are presented that involve quickly removing fluids from the tissue site to reduce or avoid maceration of the epidermis. One dressing includes a dressing material for transferring the reduced pressure to the tissue site and a drape covering at least a portion of the dressing material. The dressing material includes a hydrophobic tissue- interface layer adapted to contact the tissue site. The dressing material also includes a manifold adapted to distribute reduced pressure. The manifold may be a hydrophobic layer. The dressing material also includes one or more absorbent layers adapted to absorb liquid from the tissue site via the tissue-interface layer and the manifold. Other aspects are disclosed.

L'invention porte sur des systèmes, des procédés et des pansements destinés à appliquer une pression réduite à un site de tissu, qui mettent en jeu l'élimination rapide de fluide à partir du site de tissu pour réduire ou éviter la macération de l'épiderme. Le pansement comprend un matériau de pansement destiné à transférer une pression réduite au site de tissu et un champ recouvrant au moins une partie du matériau de pansement. Le matériau de pansement comprend une couche d'interface de tissu hydrophobe apte à entrer en contact avec le site de tissu. Le matériau de pansement comprend également un collecteur apte à délivrer une pression réduite. Le collecteur peut être une couche hydrophobe. Le matériau de pansement comprend également une ou plusieurs couches absorbantes aptes à absorber un liquide provenant du site de tissu par l'intermédiaire de la couche d'interface de tissu et du collecteur. D'autres aspects sont décrits.
