Abstract

L'invention se rapporte à un détecteur radioacoustique et électronique de liquides corporels, destiné à améliorer l'aide apportée aux personnes temporairement ou définitivement incontinentes, que ce soit des personnes âgées ou des nouveau-nés. Ledit détecteur, qui fonctionne selon deux principes fondamentaux, comprend trois parties: un capteur, un système secondaire électronique de détection et de radiotransmission et un récepteur. Le système secondaire électronique de détection et de radiotransmission est fixé et connecté électriquement au capteur, qui est intercalé entre deux films hydro-absorbants, puis est porté par un patient ou placé sous son corps. Lorsqu'ils viennent au contact du capteur, les liquides corporels imbibent rapidement les films hydro-absorbants. Le système secondaire électronique de détection et de radiotransmission est alors activé et émet un signal codé de fréquence radioélectrique en direction du récepteur, qui compare le code reçu au sien et, si l'identification est positive, produit un son intermittent. Ainsi, la personne qui a le récepteur sait en temps réel que le patient a besoin d'aide et peut intervenir aussitôt.
