    This invention relates to personal respiratory protection.
    The purpose of the invention is to increase the efficiency of thermal insulation of the apparatus.
    Figure 1 shows the apparatus, a general view; figure 2 - insulating screen.

    air, the jet of which passes through the channels 9 under the action of the so-called draft of the chimney. Due to the presence of a protruding part 11, the heat flux deviates from the sub-region, which increases comfort.
    Thanks to the execution of the ribs 7 ,. 8 thin-walled thermal conductivity inside
    The oxygen apparatus contains an outlet P of the hollow body A held on
    an oxygen-carrying cartridge 1 placed inside the breathing bag 2 located in front of the human chest. The cartridge 1 communicates with the breathing hose 3, ending with a mouthpiece (not shown), 5 and a breathing bag 2.
    On the outside of the respiratory bag 2, on the side facing the human body, there is a heat insulating screen in the form of a rectangular parallelepiped open at the top and bottom of the hollow body 4 with the plates 5 facing to the side. Plates 5 are inserted into the pads 6 placed on the breathing bag 2. Hollow The housing 4 is made of an elastic compressible material with low thermal conductivity. In the hollow body 4, thin-walled fins 7 and 8 are installed, which are spaced from one another to form air channels 9.

    1. An oxygen apparatus based on chemically bound oxygen containing a breathing hose with a mouthpiece, extracting oxygen and a cartridge with chemicals, is located. In front of a person’s chest, a breathing bag and an emergency bag, an oxygen-carrying cartridge of chemicals, is placed inside the breathing bag and communicated with it
    and a breathing hose, characterized in that, in order to increase the heat insulating efficiency, the apparatus is provided with a breathing bag installed outside the side facing the human body with heat insulating screen in the form of an open top and bottom hollow body in the shape of a rectangular parallelepiped with plates inserted to the sides inserted into the lining placed on the breathing chamber, while the hollow body is made of an elastic compressible material with low thermal conductivity.
    Side 10 of the hollow body 4, facing the human body, is made with part 11 protruding above the upper end of the body.
    Chuck 1 with a breathing bag 2 and a hollow body 4 is placed in an emergency bag (not shown).
    When placed in an emergency bag, the hollow body 4 is folded into the tight position of the packing of the oxygen apparatus.
    When put into operation, the hollow body 4 due to the elastic forces is straightened with the adoption of a predetermined shape, which allows it to perform the function of thermal protection by maintaining a certain distance to the human body and cooling the surrounding
