Patent

CA 2226100

Breathing equipment of the kind which includes a breathing hood (1) intended to surround the wearer's head (2), an inner mask (3) which covers at least the wearer's mouth and nose and a breathing gas delivery conduit (4). The equipment also includes means (6, 7) which permit gas to pass from the hood (1) to the mask (3), and check valve means (5) for passing gas from the mask (3) to the surroundings when the overpressure in the mask has reached a given value. The equipment is characterized by the combination of that the breathing gas is delivered to the hood (1) and that the means (6, 7) allow gas to pass in both directions between the hood (1) and the mask (3). The means (6, 7) therewith require a lower overpressure in the mask (3) for passage of gas from the mask to the hood than the pressure required by the check valve (5) to allow gas to pass to the surroundings.

L'invention porte sur un respirateur comportant un casque (1) entourant la tête (2) du porteur, un masque intérieur (3) couvrant au moins la bouche et le nez du porteur et un conduit d'amenée du gaz respiratoire (4). L'équipement comprend également un moyen (6, 7) permettant au gaz de passer du casque (1) dans le masque (3) et une soupape anti-retour (5) laissant partir le gaz vers l'extérieur lorsqu'il a atteint une certaine surpression. L'équipement est caractérisé par le fait qu'il combine l'amenée du gaz respiratoire dans le masque (1) avec un moyen (6, 7) permettant au gaz de passer dans les deux sens entre le casque (1) et le masque (3). Le susdit moyen (6, 7) requiert pour le passage du gaz du masque vers le casque une surpression à l'intérieur du masque (3) inférieure à celle requise par la soupape de non retour pour l'évacuation du gaz vers l'extérieur.
