FIELD: medicine.
SUBSTANCE: self-contained respiratory apparatus using chemically combined oxygen is used for respiratory system protection in emergency. The self-contained respiratory apparatus comprises a regenerative product (4) casing (3) connected by a connection (1) with a respiratory isolation assembly (2) in the form of a face mask. The regenerative product (4) casing (3) and a fan with an electric motor (6) connected to an electric battery (7) are mounted in a respiratory bag (5). On an input of the regenerative product (4) casing (3), there is a low-pressure chamber (8) connected by the connection (1) with a respiratory isolation device (2) and supplied by windows (9) connecting the chamber with a cavity of the respiratory bag (5). A base of the low-pressure chamber (8) represents a plate (10) with a hole (11) connected to the fan (6).
EFFECT: invention provides ease of use ensured by respiratory comfort, and also design simplification.
