Abstract

La présente invention concerne un masque à recirculation pour un sinistre. Selon un mode de réalisation, le masque à recirculation comprend : une unité de protection faciale portée sur le visage et la tête ; un orifice de masque formé sur une surface avant de l'unité de protection faciale, formé de façon à correspondre à la bouche, ayant un trou d'entrée formé sur un côté de celui-ci, et comportant un trou de raccordement de cartouche formé sur l'autre côté de celui-ci ; une unité de distribution de gaz raccordée à l'orifice de masque de façon à comporter un récipient de stockage d'oxygène pour distribuer de l'oxygène dans le trou d'entrée et un récipient de stockage d'air pour fournir de l'air général contenant de l'azote ; et un dispositif de réglage de gaz formé dans l'orifice de masque, et ajuster l'ouverture/fermeture et le flux d'entrée de gaz fourni par l'unité de distribution de gaz. Selon la présente invention, le masque à recirculation peut être utilisé en tant que masque à gaz respirable par purification d'air externe pollué, et peut recevoir en outre de l'air adapté pour la respiration depuis un récipient de stockage d'air et un récipient de stockage d'oxygène, disposés dans le dispositif lui-même, même lorsque l'air extérieur est coupé dans une situation de sinistre telle que dans un incendie produisant un gaz fortement toxique ou sur un navire qui coule dans laquelle l'oxygène est complètement coupé, et, par conséquent, le masque à recirculation peut améliorer remarquablement un taux de survie.
