Abstract

La présente invention concerne un capteur de dioxyde de carbone télo-expiratoire multifonctionnel qui comprend un boîtier (4) et un adaptateur (1). Le boîtier (4) est raccordé de façon détachable à l'adaptateur (1). L'intérieur du boîtier (4) est une cavité, et est pourvu d'un noyau pour détecter et analyser le dioxyde de carbone télo-expiratoire. Un capteur infrarouge (6) du noyau est agencé en correspondance avec une extrémité de transmission d'une source de lumière infrarouge (12) du noyau. Une rainure (414) est disposée sur le boîtier entre le capteur infrarouge (6) et l'extrémité de transmission de la source de lumière infrarouge (12). Au moyen du raccordement de la rainure (414) à l'adaptateur (1), une chambre à gaz pour recevoir et détecter le dioxyde de carbone est formée. L'adaptateur (1) comprend une partie d'adaptateur (110) et un évent est disposé sur la partie d'adaptateur (110). La partie d'adaptateur (110) est raccordée de façon détachable à la rainure (414). L'évent est raccordé à un tube nasal (14) ou à un circuit respiratoire. Le capteur de la présente invention peut fonctionner en combinaison avec des adaptateurs de diverses spécifications pour surveiller à la fois des patients adultes et non adultes, intubés et non intubés, et comporte différentes fonctions. Les adaptateurs pour le capteur de la présente invention sont faciles à remplacer et le capteur est facile à actionner et confortable à porter.
