Abstract

L'invention concerne un matelas présentant une valve de régulation de la pression interne, ladite valve (3), installée sur un matelas, comprend des moyens d'admission (4) et des moyens de décompression (5). Un matériau enveloppe non perméable (1) entoure un corps perméable élastique (2) de manière étanche. La pression interne dans le matelas est réglée automatiquement par la valve (3). Les moyens d'admission (4) s'ouvrent lorsque la pression interne dans le matelas descend en-dessous d'une valeur déterminée de manière à acheminer de l'air frais dans le matelas. Les moyens de compression (5) s'ouvrent, au contraire, lorsque la pression interne dans le matelas dépasse une valeur déterminée de manière à évacuer l'air piégé dans le matelas vers l'extérieur. Le corps élastique (2) du matelas est formé par la connexion d'un élément fortement élastique (21) avec un élément peu élastique (22), ceci afin d'optimiser l'élasticité du matelas automatique selon les conditions d'utilisation pour un patient.
