The generator 9 provides a continuous supply of oxygen for 30 minutes with an average flow rate of 5 nl/min at an ambient temperature not exceeding 25 degrees Celsius and atmospheric pressure 760 mm RT. Art. Pressure of oxygen at the output of the generator 9 is equal to 0.2 to 0.4 MPa. The quality of the produced oxygen meets the requirements of GOST 5583-78.

To start the reaction in the checker-reactor 16 of the generator 9, the required temperature of 500-600 degrees Celsius, which is achieved through the launching device 18 mounted on the cover 11 of the generator 9. To prevent a possible increase of the oxygen pressure in the generator 9 in the process of thermochemical reactions on the flange 12 of the box 10 has a relief valve 21 with a pressure of 0.4 MPa, which is connected with the first output checkers-reactor 16.

From the heat exchanger 23, the oxygen is supplied to the filter 27 additional purification, after passing which he used isoamsa on purpose.

To enter the proposed complex medical care to the wounded in action on the field you want to retrieve thermochemical generator 9 of the oxygen from the bag-packing, remove the quick-release clamp 14, the connecting duct 10 of the generator 9 with the cover 11, to separate the cover 11. To install the percussion mechanism 19 starter 18 (kit of spare parts) with copper sealing gasket in the Central threaded hole of the flange 12 of the cover 11 and secure it with a wrench. To open a sealed package with interchangeable pieces 16 with a special wrench; remove the piece 16, following the safety rules when working with pure oxygen, and install it in the enclosure 10 of the generator 9 so that the hole is present at one end pieces 16, was at the top. Connect the duct 10 with the cover 11 of the generator 9, while the percussion mechanism 19 launching device 18 should go into the hole checkers 16. After fixing box 10 and the cover 11C by means of a clamp 14 generator 9 is ready for use.

For starting device 18, you must delay until it stops the handle of the percussive mechanism 19 and release it after hitting the primer-igniter 32 initiates thermochemical reaction in the device 18, which starts the piece 16. At the end of the working cycle, it is necessary to remove the waste piece 16 and a trigger device 18, ISOE is isua the above-described methods of work and keeping safety measures in case of contact with surfaces, with the high temperature. Waste checkers 16 should be stored in a special device, eliminating the environmental pollution (figure 2 it is not specified), for subsequent utilization. Optionally, perezarazhenie generator 9 oxygen.

Currently used in inhalers oxygen 1.1 and ventilators 1.2, 1.3 standard gas cylinders 2 with a working pressure of 15 MPa (150 kgf/cm 2) during storage, transportation and operation require protection from impact, heat, bullets, shrapnel and other factors, the impact of each of which may cause the explosion of the oxygen tank. Railway transportation requires special conditions, as explosive cargo, aviation and transport them generally prohibited. Additional difficulties and expenses arise during the transportation of the exhaust gas cylinders to the point of filling them with oxygen.

Transportation, storage and operation of the proposed complex medical care to the wounded on the basis of the generator 9, and checkers-reactors 16, in airtight containers, deprived of many of these mentioned disadvantages. Piece 16 can withstand heat up to 300 degrees Celsius, moreover, it is assumed that a direct hit from a bullet or shrapnel will only lead to its destruction. Oxygen, sotiriadis is in the block 16, occupies a much smaller volume (0,58 DM3in comparison with standard cylinder 2 (3.8 DM3), i.e., in quantitative terms, the possibility of transporting oxygen in checkers 16 5-6 times more than in the current cylinders 2. The cost of materials for the manufacture of his checkers 16 is 389 rubles. All this allows to conclude that the advantage of using thermochemical generators 9 oxygen in the military (field) conditions in comparison with the cylinders.
