Abstract

Le dispositif comprend un détecteur avec un capteur sensible à l'humidité, un émetteur intégré et une partie de signalisation comportant un récepteur intégré et un indicateur. Le détecteur se trouve dans la couche du nourrisson ou du petit enfant; un écoulement d'urine est déterminé par l'utilisation des propriétés électriques de l'urine sur le senseur sensible à l'humidité; cette information est transmise à la partie signalisation sans fils et produit une indication acoustique ou optique. La surveillance d'un nourrisson ou d'un petit enfant est possible aussi bien dans le lit que dans la voiture ou aussi à l'extérieur. Le dispositif permet une pleine protection des nourrissons et des petits enfants contre "le mouillage".
