Title
(EN) REDUCED-PRESSURE DRESSINGS, SYSTEMS, AND METHODS EMPLOYING DESOLIDIFYING BARRIER LAYERS
(FR) PANSEMENTS À PRESSION RÉDUITE, SYSTÈMES ET PROCÉDÉS UTILISANT DES COUCHES BARRIÈRES RAMOLLISSANTES
Abstract
(EN)
Reduced-pressure medical dressings (100), systems, and methods involve a dressing (104) with a first barrier layer (112) that desolidifies when exposed to a fluid - typically a liquid - to form a treatment aperture in the first barrier that is used to deliver reduced pressure to a tissue site. The first barrier layer is formed from a desolidifying material. The system includes a drape (120) covering a second surface of a manifold (110) and a portion of the patient's epidermis (138) to provide a substantially sealed space (118) containing a manifold and the first barrier layer. Other systems, dressings, and methods are also disclosed.
(FR)
L'invention concerne des pansements médicaux à pression réduite, des systèmes et des procédés qui mettent en jeu un pansement ayant une première couche barrière qui se ramollit lorsqu'elle est exposée à un fluide — en général un liquide — pour former une ouverture de traitement dans la première couche barrière, laquelle ouverture est utilisée pour délivrer une pression réduite sur un site tissulaire. La première couche barrière est constituée d'un matériau ramollissant. Le système comprend un champ opératoire recouvrant une seconde surface d'un collecteur et une partie de l'épiderme du patient pour fournir un espace sensiblement scellé contenant un collecteur et la première couche barrière. D'autres systèmes, pansements et procédés sont également décrits.
