Abstract

L'invention concerne un compteur de gaz respiratoire servant à détecter un composant gazeux contenu dans un gaz respiratoire s'écoulant dans le trajet d'écoulement du compteur au cours de la respiration de l'utilisateur. Ce compteur comprend un détecteur de gaz respiratoire placé sur le trajet d'écoulement du compteur. Un détecteur de gaz respiratoire comprend un détecteur de gaz fluorescent pourvu d'un émetteur de rayonnement qui dirige le rayonnement dans le trajet d'écoulement, et un détecteur de rayonnement qui détecte la fluorescence du gaz respiratoire induite par rayonnement. Le détecteur de gaz respiratoire comprend également un filtre à bande étroite placé entre le détecteur et le gaz, qui permet de passer le gaz fluorescent au détecteur de rayonnement, et de détecter ainsi instantanément les composants du gaz respiratoire traversant le trajet d'écoulement. Un autre détecteur de gaz respiratoire comprend un détecteur micro-usiné qui détecte l'oxyde d'azote par les variations de la fréquence de résonance de la structure micromécanique dues à l'absorption d'oxyde d'azote sur la surface de la structure.
