Abstract

L'invention concerne un dispositif de surveillance de lits de patients, servant à détecter si le patient se lève de son lit ou s'il se couche dans son lit. Le lit est équipé d'un matelas et d'un dispositif d'alarme destiné à alarmer le personnel soignant. La partie centrale du matelas comporte, le long d'au moins une des arêtes longitudinales, une rangée de capteurs de proximité. Lorsqu'une contrainte est appliquée à une des arêtes du matelas, un signal est produit et celui-ci actionne le dispositif d'alarme.
