REGENERATIVE CARTRIDGE OF SELF-CONTAINED BREATHING APPARATUS Russian patent published in 2019 - IPC A62B7/08 

FIELD: chemistry.

SUBSTANCE: invention refers to insulating respiratory apparatuses on chemically bound oxygen intended for protection of respiratory apparatus in an emergency situation. Regenerative cartridge of the insulating respiratory apparatus on chemically bound oxygen contains a regenerative product, a filter-refrigerator and a starting device consisting of a housing, in which starting briquette and an ampoule with an initiating liquid are installed. According to the invention, the launching device housing is equipped with a threaded socket and is connected to the cartridge body by a threaded nozzle connecting the cavity of the launching device housing to the cavity of the regenerative cartridge. In the starter housing between the ampoule with initiating liquid and starting briquette there is a gasket equipped with gas passing channels on the side facing the starting briquette, and between the start briquet and the bottom of the housing there is a gasket equipped with gas passage channels on both sides.

EFFECT: invention provides breathing comfort, increased degree of regenerative product development and higher reliability of the insulating respiratory apparatus due to more reliable cartridge start-up.
