Abstract

L'invention concerne un système d'analyse d'haleine servant à détecter des composés cibles. Ce système comprend un masque (12) destiné à être placé sur la bouche d'une personne et comprenant des passages (22, 25, 30, 35) qui permettent l'inspiration et l'expiration d'air. Un détecteur électronique (40) placé au niveau d'une soupape (102) située à l'entrée d'un premier passage de sortie (25) entame la détection d'une première expiration et déclenche un signal de commande.
