Abstract
La présente invention concerne un dispositif de respiration d'oxygène à déploiement automatique. Lorsque l'oxygène stocké dans un réservoir de stockage d'oxygène est épuisé, un utilisateur, tel qu'un pompier ou autre, peut faire entrer manuellement de l'air extérieur, qui est filtré à l'aide d'une partie pompage, constituée d'un élément de levier, d'un élément de pompe et d'un élément de filtre, dans le réservoir de stockage d'oxygène afin d'empêcher facilement que l'utilisateur, tel qu'un pompier ou analogue, n'ait des difficultés à respirer.
