Title (EN) COMPOSITE DRESSINGS FOR IMPROVED GRANULATION AND REDUCED MACERATION WITH NEGATIVE-PRESSURE TREATMENT
(FR) PANSEMENTS COMPOSITES DE GRANULATION AMÉLIORÉE ET DE MACÉRATION RÉDUITE AVEC TRAITEMENT À PRESSION NÉGATIVE
Abstract:
(EN) Dressings for tissue treatment with negative pressure and methods of using the dressings for tissue treatment with negative pressure, which may comprise a dressing having at least three layers assembled in a stacked relationship. The first layer may comprise or consist essentially of a polymer film having a plurality of fluid restrictions that are normally unstrained or closed. The second layer may comprise a manifold, and the third layer may comprise or consist essentially of a polymer drape. A fourth layer, which may be coupled to the first layer opposite the second layer, may comprise or consist essentially of a silicone gel having a plurality of apertures. In some examples, the plurality of apertures in the fourth layer may be registered with the fluid restrictions of the first layer.
(FR) La présente invention concerne des pansements pour un traitement de tissu à pression négative et des procédés d'utilisation des pansements dans un traitement de tissu à pression négative, qui peuvent comprendre un pansement ayant au moins trois couches assemblées de façon empilée les unes par rapport aux autres. La première couche peut comprendre ou consister essentiellement en une pellicule polymère ayant une pluralité de restrictions fluidiques qui sont normalement non sollicitées ou fermées. La deuxième couche peut comprendre un collecteur, et la troisième couche peut comprendre ou consister essentiellement en un drapé de polymère. Une quatrième couche, qui peut être couplée à la première couche opposée à la deuxième couche, peut comprendre ou consister essentiellement en un gel de silicone ayant une pluralité d'ouvertures. Dans certains exemples, la pluralité d'ouvertures dans la quatrième couche peut correspondre aux restrictions fluidiques de la première couche.
