Abstract

Ce dispositif est du type de ceux comportant un appareil mesurant la concentration d'alcool dans l'air expiré, qui effectue sa mesure à un moment établi par une commande, et un détecteur d'erreur décelant le sens d'écoulement de l'air repiratoire, qui établit la nullité de la mesure lorsque cet air, au début de l'expiration, mais avant le moment de la mesure, s'écoule dans le sens de l'inspiration. Dans le dispositif selon l'invention, le détecteur d'erreur 327, pour identifier le sens d'écoulement de l'air respiratoire, compone un circuit différentiel 333, ainsi qu'une résistance variable avec la température 329, par exemple une thermistance, placée sur le parcours de l'air respiratoire (canal 1) et montée entre une source de tension 331 et le circuit différenciateur.
