FIELD: medicine; life saving equipment.

SUBSTANCE: invention concerns isolating respiratory apparatus using chemically combined oxygen, intended for protection of respiratory system in an emergency situation. The isolating respiratory apparatus using chemically combined oxygen contains the regenerative cartridge with a regenerative product, a respiratory bag with the overpressure valve, a facial part and the actuating unit consisting of a starting briquette and an ampoule with the initiating liquid. The ampoule is supplied by the union tightly connected with a respiratory bag by means of a skirt from an elastic material. The ampoule and an actuating briquette are concluded in the punched case established on a cover of the regenerative cartridge with a backlash. The ampoule and the actuating briquette are eccentrically established in the punched case, and the eccentric washer is established between an ampoule and a starting briquette. The actuating briquette and an eccentric washer are placed in a hydrophylic cover with an aperture under an ampoule. The sleeve from an elastic material is established on the skirt. The projecting lobe is executed on the case of the regenerative cartridge with a carving nest for the equipment of the punched case of the actuating unit. Reliability increase when starting the apparatus.

EFFECT: reliability increase when starting the respiratory apparatus.
