Abstract

La présente invention concerne un masque à gaz d'évacuation d'urgence possédant une structure de port triple comprenant un tube en silicone, une extrémité de serrage et une bande de liaison de sorte que le masque puisse être porté rapidement et que son ouverture présente une étanchéité à l'air améliorée en cas d'incendie. De plus, le masque à gaz possède une structure double comprenant une membrane interne et une membrane externe comportant un élément d'espacement interposé entre elles pour former une partie d'espace de façon à filtrer doublement un gaz toxique, ce qui en améliore par conséquent la performance de filtration. En outre, le masque à gaz permet une alimentation en oxygène à haute pression lorsqu'il est porté, de façon à réduire une proportion de monoxyde de carbone par l'intermédiaire de l'oxygène à haute pression fourni, et l'oxygène à haute pression, ayant traversé une membrane interne pendant la respiration, augmente une force de liaison de l'oxygène à l'hémoglobine par rapport à une force de liaison du monoxyde de carbone à l'hémoglobine.
