Abstract

L'invention concerne un système d'alerte. Le système d'alerte visuelle ou acoustique consiste en un coussin d'air anti-escarres (figure B - 2b) monté sur un fauteuil roulant ou de repos (figure B - 3). Le coussin d'air est équipé de capteurs (figure B - 4) pour mesurer la pression, la température et l'humidité, comprenant une boîte de commande (figure B - 5) pour la régulation des capteurs en question. Le coussin est divisé en une ou plusieurs sections (figure B - 6). Les pressions (figure A - 9) des sections sont lues en liaison avec une analyse de la posture assise (figure A - 8). En cas de variation des pressions des sections, la boîte de commande assure le déclenchement d'une alerte et la régulation des pressions. Un modèle spécial est connecté à une pompe électrique (figure B - 7) et un automate programmable (figure C - 20). La pompe électrique alterne les pressions des sections. En conséquence, le fauteuil a un effet massant et la circulation sanguine est augmentée. En outre, un système de climatisation (figure B - 21) est connecté à un autre modèle spécial. La boîte de commande (figure B - 5) et le système de climatisation (figure B - 21) déclencheront les alertes et réguleront l'humidité relative autour des capteurs (figure B – 4b) et (figure B – 4c). Ceci garantit des conditions optimales pour le bien-être du patient ainsi qu'une circulation sanguine optimale. L'invention est particulièrement adaptée pour la prévention des escarres (escarres de décubitus) (photo 1- figure 1).
