  • the average pressure per unit area applied to the sacrum of the air mat is always higher than the critical value for pressure ulcer occurrence, and is about three times the average value of the present invention. A significant difference was found in the decompression capacity compared to the conventional air pressure fixed air mat.

Abstract

Cette invention concerne un matelas destiné à la prévention des escarres et sur lequel la pression contre des parties comme l'os sacrum pouvant entraîner des escarres est maintenue en dessous de 30 mm Hg/cm2, valeur critique à partir de laquelle apparaissent les escarres si la pression se maintient trop longtemps. Ce matelas comprend un corps (1) en forme de sac comportant des renfoncements rectangulaires parallélépipédiques dans sa partie centrale et sur ces deux côtés, ainsi que des supports auxiliaires (2) en forme de sac et conçus pour venir se loger dans lesdits renfoncements. L'épaisseur de ces supports auxiliaires (2) est inférieure de plusieurs centimètres à celle du corps (1) de manière à créer une différence de niveaux. Le corps (1) est gonflé avec de l'air, tandis que les supports auxiliaires sont remplis d'eau à 60 % de leur capacité. Grâce à ce système de matelas, la majeure partie du poids du corps humain repose sur le corps (1) et très peu sur les supports auxiliaires (2). Ainsi, l'os sacrum, le grand trochanter et l'os iliaque, qui sont sujets à des escarres et supportés par les sous-supports, reçoivent une pression moindre que d'autres endroits supportés par ledit corps (1).
