Abstract

L'invention se rapporte à la réalisation d'une compresse pour la prévention efficace des escarres de décubitus, qui comprend: des coussinets servant de support aux parties sensibles aux escarres; des commutateurs à capteurs placés sur les parties sensibles aux escarres et mis sous tension lorsque s'exerce sur ces parties une pression supérieure à une pression d'escarre; des électrodes découvertes qui sont disposées autour des parties sensibles; et un contrôleur. Le contrôleur fournit du courant à basses fréquences lorsqu'une pression se prolonge pendant une période prédéterminée, produit un accroissement de la valeur de courant avec l'augmentation du temps de prolongement de la pression et prolonge l'amenée de courant même après l'arrêt de la pression, lorsque la pression se prolonge pendant une période prédéterminée. Lorsque la pression se prolonge, l'amenée de courant empêche le ralentissement de la circulation sanguine, favorise les effets facilitant la circulation sanguine pendant le prolongement de la pression, et en outre accélère le rétablissement de la circulation sanguine après l'arrêt de la pression. Grâce à l'amenée de courant, on peut prévenir tout atrophie par inactivité d'un groupe de muscles autour de la partie sensible aux escarres, permettant ainsi la dispersion de la charge produite par la pression sur la partie sensible.
