Abstract

Un pansement pour blessures hypoadhésif, ayant une couche en contact avec la plaie, comprend un film polymère, tel qu'un film en polyuréthane, dont l'indice de perméabilité à l'humidité est d'au moins 500gm-2 24h-1 à une température de 37°C et dans des conditions d'humidité relative comprise entre 10 et 100 %, lorsque le film est en contact avec de la vapeur d'eau. La surface dudit film qui est contact avec la plaie a une force d'adhésion (telle qu'elle est décrite dans la présente invention) ne dépassant pas 30jm-2.
