Abstract

L'invention concerne une thérapie améliorée destinée à éliminer du sang le monoxyde de carbone et les substances chimiques anesthésiques indésirables, et à réoxygéner rapidement le sang désoxygéné à cause d'un empoisonnement au monoxyde de carbone ou d'une inhalation de fumée. La thérapie utilise par ailleurs un dispositif d'administration thérapeutique destiné à doser l'oxygène et le dioxyde de carbone, et un appareil mélangeur de gaz sous pression, notamment destiné à des respirateurs et à des dispositifs médicaux ayant plusieurs tuyaux d'alimentation en gaz comprimé, reliés à un dispositif mélangeur pour effectuer une distribution dans un détendeur (260) (un respirateur ou un masque). La thérapie utilise également un dispositif de sélection des gaz (5), un obturateur d'arrêt automatique du dioxyde de carbone (70), un système de purge (290), le mesurage des gaz et une chambre de mélange, destinés à obtenir un mélange homogène des gaz et dimensionnés pour être utilisés sur le terrain par des auxiliaires de soins d'urgence. La thérapie consiste en un mélange de dioxyde de carbone et d'oxygène destiné à favoriser une oxygénation rapide du sang dans des cas d'empoisonnement au monoxyde de carbone, d'inhalation de fumée et d'autres cas de faible taux d'oxygène.
