REGENERATIVE CARTRIDGE OF ISOLATING BREATHING APPARATUS Russian patent published in 2013 - IPC A62B19/00 

FIELD: salvage appliances.

SUBSTANCE: invention relates to isolating breathing apparatuses on chemically bound oxygen. The regenerative cartridge of the isolating breathing apparatus on chemically bound oxygen comprises a start-up briquette, a regenerative product. The start-up briquette is installed at the inlet of the cartridge and is made in the form of a multi-channel heat resistant unit. The regenerative product in the form of a layer of a grained regenerative product and in the form of multi-channel units from potassium superoxide. The cartridge is serially filled with a regenerative product from potassium superoxide in the form of multi-channel units, which adjoin the start-up briquette and grained regenerative product from potassium superoxide. Arrangement of channels in the start-up briquette corresponds to arrangement of channels in multi-channel blocks.

EFFECT: invention provides for comfort of breathing, higher extent of regenerative product use and higher reliability of cartridge operation under lower temperatures.
