    1. Respiratory protection device as an escape apparatus with reciprocating respiration, comprising a chemical cartridge (1) generating oxygen, a respirator bag (5) connected to the chemical cartridge (1), the chemical cartridge being secured with its inlet opening (D) on the top end face of the respirator bag and a respirator hose (3) with a mouthpiece (4), as well as an ever-ready holder (7) receiving these parts, characterised in that a) the chemical cartridge (1) is arranged inside the respirator bag (5) and is wholly ensheathed thereby, in such a way that the outer surface (A) of the chemical cartridge is surrounded on all sides by a free space within the respirator bag when the apparatus is in operation, and b) the chemical cartridge (1) is closely enwrapped by a thermally insulating covering (2) and that the covering (2) forms a unit with the respirator hose (3).

    The invention relates to the means of individual protection of the respiratory organs from harmful substances, in particular to the self-rescuer.
    The purpose of the invention is to reduce the overall characteristics of the respirator while ensuring low temperature of its surface and inhaled air, as well as providing anti-shock protection.
    Figure 1 shows a respirator with a mantra breathing circuit; in FIG. 2, section A-A in FIG. 1; FIG. 3 shows a respirator with a circular breathing pattern; 4, a respirator placed in a case; on fig.Z - node I in figure 4.
    The respirator contains a cartridge 1 with chemicals that release oxygen, which is covered by a thermal insulating and impact-resistant casing 2, a breathing hose 3 with a mouthpiece 4, a breathing bag 5 attached to the cartridge 1 and a carrying strap 6 ,
    Above the inlet 8 of the cartridge 1 is a heat exchanger 9, insulated from the cartridge 1, the heat exchanger 9 is enclosed in a heat-insulating casing 10, which is located on the upper side of the cartridge 1 in the bag 5, the opening 12 is enclosed in the mandrel 13, to which the cartridge 1 is attached with the sheath 2 and through the arms 14, the ends of the carrying belt 6. The safety valve 15 is located on the upper face side 11 of the respiratory

    bag 5. The arms 14 are made with heat insulating coating.
    The shell 2 is made with ribs 16, which are firmly attached to the surface 17 of the cartridge 1 and spaced parallel to the vertical or longitudinal axis of the cartridge 1. 1 for the passage of inhaled and exhaled air (FIG. 1).
    The upper end surface of the cartridge 1 is completely enclosed by the shell 2, which advantageously forms a single whole with the breathing hose 3.
    The shell 2 is made of insulating material, the ribs 16 are formed with the surface 17 of the cartridge 1 cavity 19.
    The cartridge 1 has an air outlet surface in the form of a dome 20 placed inside the cartridge 1,
    The design of a respirator with a circular breathing pattern (Fig. 3) is identical to a respirator with a butterfly breathing circuit (Fig. 1) except for the housing 21, two inhalation valves 22 and the heat exchanger 9. The housing 21 with the possibility of plug-in input is connected to the inlet 23 of the cartridge 1 namely, by means of a nozzle 24 inserted into an outlet 25 connected to the housing 21. A nozzle 24 is inserted into the connection 25 with a seal 26, The shell 2 is formed with slots 27.
    The cartridge 1 with the breathing bag 5, the hose 3 with the mouthpiece 4 is placed in the non-working position in the case 7,

    Zap respirator (seeking shock by using ring-shaped bulges 30 formed at the top or bottom).
    The device works as follows.
    Exhaled air through the hose 3 enters the heat exchanger 9, the cartridge 1 and passes in its upper part through chemicals down the axis and in the side radially from the outside to the inside. The flow of air through the cartridge is indicated by arrows. Breathing is in the opposite direction from the breathing bag.
    During the circulating breathing process, inhalation is carried out directly from the breathing bag 5 through the slots 27, the hose 3 is used both for inhalation and for breathing.
    In both breathing patterns, sheath 2 contributes to the fact that the heat load in the working state, due to the exothermic reaction of chemicals that release oxygen, to the breathing bag 5, surrounding the cartridge 1 is very small. Due to the fact that the shell 2 is made with ribs 16 adjacent to the surface 17 of the cartridge 1, cavities 19 are created between the surface 17 and the shell 2, which serve as thermal insulation and reduce the temperature of the surface of the cartridge 1. Making the shell 2 with edges 16 facilitates In addition, the shell is pulled on the cartridge during installation, reducing the weight of the shell 2, which reduces the weight of the entire device. The rigidity of the shell 2 increases, in addition, the respirator is protected from impacts when placed in the case 7.
