Abstract

Procédé pour la fabrication d'un pansement médical polyvalent offrant une protection suffisante contre les bactéries et présentant de bonnes propriétés mécaniques et lyophiles. Une feuille de mousse de polyuréthane à alvéoles ouverts non comprimée de 0,5 à 10 mm d'épaisseur est ramollie à l'une de ses surfaces, sans décomposition thermique, jusqu'à obtention du pouvoir adhésif voulu et est reliée ensuite, de manière perméable aux gaz et à la vapeur d'eau, à une feuille de mousse de polyuréthane souple comprimée irréversiblement de façon que son épaisseur soit réduite de 2 à 30 fois, l'ensemble ainsi obtenu étant ensuite nettoyé par voie physique et/ou chimique. L'invention est applicable en particulier au traitement de brûlures et analogues.
