Abstract

L'invention concerne un détecteur de dioxyde de carbone comprenant un substrat de borosilicate. Ce détecteur peut également comprendre une solution indicatrice de dioxyde de carbone disposée sur le substrat de borosilicate. Ce détecteur de dioxyde de carbone peut former une partie d'un système de détection de dioxyde de carbone comprenant également une entrée d'air raccordée de manière fonctionnelle au boîtier pour permettre à l'air de parvenir jusqu'au détecteur de dioxyde de carbone. Le détecteur de dioxyde de carbone peut comprendre un substrat de borosilicate et une solution indicatrice réagissant au dioxyde de carbone, disposée sur le substrat de borosilicate. Le détecteur peut faire partie d'un autre système tel qu'un système de réanimation. On peut produire ce détecteur en humidifiant un substrat de borosilicate avec une solution indicatrice réagissant au dioxyde de carbone, puis en séchant la solution indicatrice pour l'immobiliser et former un détecteur de dioxyde de carbone sec. Ce détecteur peut être utilisé pour détecter la concentration de dioxyde de carbone dans un échantillon d'air, par exposition du détecteur à l'échantillon.
