Abstract

La présente invention concerne un appareil respiratoire éliminant les poussières fines et comportant un clapet d'évacuation sur le masque nasal, le clapet d'évacuation se trouvant sur le masque nasal afin d'empêcher l'air expiré de s'écouler en sens inverse jusqu'à un filtre, ainsi qu'un appareil respiratoire éliminant les poussières fines comportant un clapet d'évacuation sur le masque nasal, le clapet d'évacuation étant installé sur le masque nasal relié par un tuyau de raccordement souple à un filtre, et comportant un passage pour les gaz d'échappement dans lequel est installé le clapet d'évacuation, lequel passage, dont la largeur se réduit progressivement, est orienté vers le clapet d'évacuation. La pression est réduite dans le passage destiné aux gaz d'échappement lorsque l'air expiré est évacué de telle sorte que l'air expiré ne pénètre pas dans le tuyau de raccordement et soit évacué à travers un orifice destiné aux gaz d'échappement. Ainsi, on empêche l'air expiré de s'écouler en sens inverse en direction du tuyau de raccordement et de pénétrer dans le nez lors de l'inspiration.
