Abstract

L'invention se rapporte à un matériau pour pansement, qui contient au moins des macromolécules ayant un point de transition sol-gel en solution aqueuse. Ce matériau est en substance insoluble dans l'eau à une température supérieure au point de transition sol-gel et il est à l'inverse soluble dans l'eau à une température inférieure à ce point de transition sol-gel. Etant donné qu'il peut être maintenu à l'état de solution sur la surface d'une plaie, ce matériau pour pansement reste solidement appliqué sur la surface d'une plaie même de forme compliquée. Ce matériau pour pansement forme en outre un pansement qui est capable de se transformer rapidement en gel à la température de la plaie et qui reste solidement appliqué sur la surface de la plaie avec stabilité. Ce pansement est stable, dans le sens qu'il ne se dissout pas sous l'effet de l'exsudat s'écoulant de la surface de la plaie et il favorise le processus de guérison étant donné qu'il empêche la sécrétion d'exsudat à la surface de la plaie, aussi longtemps qu'elle n'est pas cicatrisée.
