N 14/7 /. A device for supplying oxygen includes a thermochemical generator of oxygen, a receiver, a piping system with instrumentation and shut-off and control equipment and means for connecting to a consumer.

The main disadvantages of the device is an analogue:

1). There is no design and a specific relationship between the device for supplying oxygen and a thermochemical generator with industrial oxygen sets-devices, oxygen consumers, for example, with devices ДП-11, ДАР-05, inhalers KI-4.02 and other sets; oxygen consumers themselves are also not indicated.

2). The design of the means of connecting to the consumer is absent and its technical solution is not technologically disclosed.

3). The piping system with control and measuring and locking-regulating equipment in the analogue are absent and require a specific technical solution.

The closest technical solution, selected as a prototype device, is an installation for producing oxygen from atmospheric air, - RF patent N 2140806 for the invention of the patent owner - Design Bureau "Armature", author A.T.Logunov, according to application N 98122564/12. - Priority dated 12/08/98, published on 10/11/1999 - bull. N 31.- M .: FIPS ROSPATENT / 8 /.

A device for producing oxygen from atmospheric air includes an adsorption oxygen concentrator containing a receiver, two adsorbers filled with a sorbent, a compressor with a drying unit and a control system, and the inlet pipes of the adsorbers are connected to the compressed air supply system, the pipelines of which connect the adsorbers to the receiver, a source of compressed air, a consumer of oxygen and them among themselves. The hub control system includes adsorption-desorption valves, valves, constriction devices such as consumable washers installed on the first and second pipelines, the latter connecting the outlet pipes of the adsorbers / 8 /. In this case, the diameters of the holes of the consumable washers are determined from the condition of achieving the maximum oxygen concentration.

The main disadvantages of the device prototype are:

1). There is no specific relationship between the plant for producing oxygen from

atmospheric air - an adsorption oxygen concentrator with industrial oxygen complexes - oxygen consuming devices, for example, with IVL DAR-05, DP-11, "Phase-11" devices, inhalation anesthesia of the "NARKON-2" type and oxygen inhalation of the KIS-2.02 type (KI -4.02), the oxygen consumers themselves are not even given.

2). The design of the means of connecting to the consumer is absent and its technical solution is also not technologically disclosed.

3). The piping system with instrumentation and locking and control equipment, operation indicators and controls in the prototype are absent and require a specific technical solution.

The main disadvantage of KI-4.02 oxygen inhalers and DP-11, DAR-05, etc. artificial lung ventilation apparatuses is that they currently use standard 2 liter gas cylinders filled with oxygen with a working pressure of 15 MPa (150 kgf / cm ² ), during storage, transportation and operation require protection from shock, heat, bullets, shell splinters and other factors, the impact of each of which can cause an oxygen cylinder to explode. Moreover, transportation by rail requires special conditions, such as explosive cargo, and transportation is generally prohibited by aviation. Additional difficulties and, consequently, significant costs arise when transporting spent oxygen cylinders to points of filling them with oxygen.

For technical support of the long-term operation of wearables IVL, IK, IN in forced modes, an oxygen source is needed that maintains its flow rate around the clock in the range from 50 to 165 nl / min and the outlet pressure of at least 0.66 MPa. The installation of atmospheric air separation in the form of an adsorption oxygen concentrator (ACC) to ensure such a range of regulation of its performance, up to almost a 9-fold change in the maximum flow rate, should either be designed for the maximum range (165 nl / min), or equipped with a receiver for accumulation of such a supply of oxygen with its subsequent consumption in the required amount. At the same time, the problem of the uninterrupted supply of oxygen must also be solved. In the first case, the management of such a large capacity while maintaining the oxygen concentration by volume of at least 90% is possible only by reducing its value from the calculated one, which will lead to a deterioration in all operational and economic indicators of the installation for producing oxygen from atmospheric air. In the second case, the installation of the ACC should be supplemented by a significant receiver and an air-compressing compressor, the compression ratio of which should be at least 30-35. The creation and inclusion of an oxygen compressor for atmospheric separation in an air separation unit is a rather complicated technical task, leading to a sharp increase in energy consumption, the cost of the installation as a whole and the loss of its most important advantages. The way out of this situation is possible and achieved by using the combination of two types of generators - ACC and on-board thermochemical oxygen generators, interacting with each other and devices using manual and automatic switching, to ensure forced operation of the devices in the range (50-165) nl / min four gases (hyperoxic gas mixture, oxygen, compressed air, nitrous oxide).

The objective of the invention is to increase the efficiency of providing oxygen to the victims at the advanced stages of medical evacuation by increasing the safety, mobility and duration of operation of the ventilator, IR, IN devices due to the round-the-clock increase in forced oxygen consumption in the range (50-165) l / min at the pressure at the outlet of the oxygen source not less than 0.66 MPa, manual, without the use of tools, and automatic connection - disconnecting the ventilator, infrared, ID devices to an oxygen source, and the entire autonomous complex is provided oxygen affected - to a source of electricity.

The problem is solved by an autonomous complex providing oxygen to the victims, including simultaneously operating onboard thermochemical generators and a portable adsorption generator for producing a hyperoxic gas mixture created on the basis of adsorption separation of atmospheric air by compressing and supplying compressed air to two adsorbers filled with adsorbent with a receiver, then connecting an oxygen concentrator and use it for mechanical ventilation, oxygen inhalation inhalation anesthesia using wearable devices, kits. At the same time, oxygen is additionally produced using on-board generators by thermochemical decomposition of the solid oxygen-containing checker composition in the reactors of thermochemical oxygen generators used as spare receivers, which are combined with the GHS adsorption concentrator into an autonomous complex providing oxygen to the advanced stages of medical evacuation. As a result, an uninterrupted, accelerated supply of the oxygen mixture from the GHS adsorption concentrator and oxygen from thermochemical generators to the IVL, IK, IN devices in the range (50-165) l / min in combination with a quick, tool-free connection and disconnection using multiple switching the lines of IVL, IK, IN devices to the GGS adsorption concentrator, thermochemical (operators and an air compressor, IN devices to nitrogen oxide cylinders, as well as all units of the autonomous complex, including wearable f ventilators, IR, IN - to the power supply network, while providing continuous optical indication of the gas pressure in the switched gas supply lines, oxygen, compressed air and nitrous oxide, as well as visual monitoring of the presence of electricity in the network and signaling the minimum threshold pressure values of these gases. To do this, the input flexible reinforced hoses of the supply lines of GGS, oxygen, compressed gas (from the compression unit of the adsorption concentrator), nitrous oxide from the cylinders are connected to the inlet fittings with the return valves of the gas switching device, and its (gas commutator), output gas valves for gas, oxygen, compressed air and nitrous oxide (two for each gas) are connected with the help of output flexible hoses to wearable devices IVL, IK, IN. With the condition of tightness of all connections by repeated docking-undocking of gas valves with plugs, manual and automatic switching of gas lines is carried out, through which the following gases are supplied to the inputs of the IVL, IK, IN devices:

hyperoxic gas mixture supplied from an adsorption concentrator, with an oxygen concentration of 40% to 93%, an overpressure of (0.2-0.4) MPa, a temperature not exceeding the ambient temperature of more than 5 ° C, a flow rate of 10 to 20 l / min;

oxygen supplied from thermochemical generators with an oxygen concentration of 99.3%, an overpressure of 0.4 MPa, a temperature not exceeding the ambient temperature of more than 5 ° C, a flow rate of 20 to 40 l / min;

air supplied from the compression unit of the adsorption concentrator, with an overpressure of not more than 1 MPa, a temperature not exceeding the ambient temperature by more than 5 ° C, flow rate up to 100 l / min;

nitrous oxide supplied from cylinders with nitrous oxide through a reducer that provides overpressure (0.2-0.4) MPa at the outlet.

When switching gases, they provide the possibility of supplying simultaneously to two GHS gas outlet valves from an adsorption concentrator either oxygen from thermochemical generators or a mixture thereof to ensure forced (up to 165 l / min) IVL (IR) modes. Moreover, in the latter case, they automatically switch to the oxygen supply from thermochemical generators when the adsorption concentrator fails or the GHS pressure drops below the allowable limit, provide compressed air to the second pair of gas valves from the compression unit of the adsorption concentrator, while the GHS supply is turned off, and to the third pair gas valves supply nitrous oxide from gas cylinders with a gearbox, and the choice of supply to the easily disconnected outlet gas valves of compressed air, GGS, oxygen (two for each gas) or their mixture is carried out manually by switching the operating modes, and the connection of wearable devices of the type "Phase-11", DAR-05, DP-11, sets of the type KIS-2.02, KI-4.02, "Narcon -2 "to the outlet gas valves of the gas switch is produced using the plugs of the outlet hoses. The operators of the complex are informed of the achievement of the lower permissible pressure values of compressed air, HGS, oxygen and nitrous oxide with the help of optical indicators and sound alarms, the first being notified from a distance of at least 1 m in the illuminance range up to 200 lux, and the second with pulsed sound signals for which the pulse frequency (150-1000) Hz, the pulse duration (150-200) ms and the amplitude - 80 dB.

The first and second valves 13-1, 13-2 serve to stop or prompt the flow of HGS supplied to the consumer and for gas analysis, respectively. The fittings are used for receiving compressed air from a source of compressed air, issuing the produced GHS to the consumer 12 (20, 21, 22) and supplying the GHS for gas analysis, respectively. The silencer 16 is designed to suppress the aerodynamic noise of a gas stream generated during the drainage of compressed gas from adsorbers 10-1, 10-2.

The control unit 5 performs automatic regulation and control of the output parameters of the oxygen concentration. He gives signals for the operation of electro-pneumatic valves 11-1, 2, 3, 4, 5, 6 according to the cyclogram laid down in it. In accordance with this, the first electro-pneumatic valve 11-1 and the fourth electro-pneumatic valve 11-4 and the compressed air from the compressed air source through the first fitting, the first non-return valve OB 11a and the open first electro-pneumatic valve 11-1 are first opened to the inlet of the first adsorber 10-1. As compressed air passes through the adsorber 10-1 zeolite layer in the pores of the latter, predominant absorption of nitrogen molecules occurs, as a result of which the nitrogen concentration in the stream decreases, and the oxygen concentration increases. Thus, at the end of the zeolite layer, a volume of gas with a high oxygen content (GHS) accumulates, which flows through the fifth non-return valve OB 11a-5 into the receiver 9, and through the first valve 13-1 and the second fitting is supplied to the consumer 20, 21 or 22.

After a certain time, the fifth electro-pneumatic valve 11-5 and GGS open through the third non-return valve OB 11a-3 and the first throttle washer 14-1 enters the second outlet fitting to purge it and remove previously absorbed nitrogen. After the purge is completed, the 4th electro-pneumatic valve 11-4 closes and the filling of the second GGS outlet fitting begins to the pre-absorption pressure. After reaching the pre-pressure in the second outlet fitting, the second half-cycle of the pneumatic circuit of the oxygen concentration unit 3 begins. At the signal of control unit 5, the first electro-pneumatic valve 11-1 closes, the second and third electro-pneumatic valves 11-2 and 11-3 open, filling of the second outlet fitting with compressed air from its source and drainage of the “exhaust” gas from the first adsorber 10-1 through the third electro-pneumatic valve 11-3 and silencer 16 noise into the atmosphere.

The second half-cycle is completely identical to the first, with the only difference being that the second and sixth electro-pneumatic valves 11-2 and 11-6 are involved in the work, and the second adsorber 10-2 is producing. The change of half-cycles by the signal of the control unit 5 ensures the continuity of the pneumatic circuit and the continuity of the production of GHS. If it is necessary to analyze the oxygen content in the GHS, an oxygen gas analyzer 15 is connected to the third fitting, the second valve 13-2 is opened, and the percentage of oxygen is measured.

The electrical circuit diagram of the control unit 5 consists of microcircuits, switches, indicators, a resonator, capacitors, rectifier units, transistors, thyristor optocouplers, thyristors, fuse links, resistors, connectors, transformer, inductor. Fusible inserts are designed to protect the circuits of the control unit 5 from short circuits and overloads. The indicators serve to reflect the state (on / off) of valves 13-1, 2, 3, 4, 5, 6 and to signal the presence of an alternating voltage of 220V in the control unit 5. Thyristor optocouplers are used for galvanic separation of control circuits and power circuits, as well as for controlling thyristor keys. Thyristors turn on and off the power supply circuits of valves 13-1, 2, 3, 4, 5, 6. The switches are designed to set the on-time state of valves 13. Microcircuits are used to form a time sequence (sequence diagram) for issuing control signals in accordance with a given time switch. In the mode of stopping the cycle after pressing the "stop" button, regardless of what time point (the point of the cyclogram) is turned off, the operation of the control unit 5 continues until the first electro-pneumatic valve 10-1 is turned on, after which the cycle is interrupted. Thus, the next time the oxygen concentration unit 3 is turned on, the cycle begins with the operation of the first adsorber 10-1. This provides a practical inertia-free operation of the concentration unit 3, since the oxygen concentration in the HGS is established after processing one or two cycles (1-2 minutes).

The adsorbers 10-1.2 are used to create a closed airtight volume to accommodate the adsorbent layer, to ensure that the latter is compressed to reduce its mechanical wear during cyclic pressure changes, and to pre-clean the GHS stream from mechanical particles formed during abrasion of the adsorbent granules. Filtration of compressed air flows is ensured by the installation in both filters 8 of a stainless steel mesh with a mesh size of 20 μm. The maximum working gas pressure in the adsorbers 10-1.2 is equal to 1 MPa.

The receiver 9 is designed to create a closed sealed volume for the collection of GHS from the output of the adsorbers 10-1.2 and fine filtration of the GHS from mechanical impurities before issuing it to the consumer 20-22. The maximum working gas pressure in the receiver 9 should also not exceed 1 MPa. The internal volume of the receiver 9 is 10 dm ³ . As a filter element 25, an EPMF-0.25 / 0.15-A-250M membrane filter manufactured by NPP Tekhnofilter was used, having a length of 250 mm, a diameter of 70 mm, a maximum pressure drop of 0.4 MPa at 20 ° C and 0, 25 MPa at 60 ° C, a maximum temperature of 60-65 ° C and an average pore size of 0.25 / 0.15 microns. The material of the fluoroplast-42L membranes is chemically resistant in concentrated and diluted strong and weak acids, in alkalis and in alcohols.

An oil-free 6 compressor LF-15-10E manufactured by the Belgian concern Atlas Copco was used as a unit for compressing atmospheric air-compressing it to a pressure that provides a short-cycle, adsorption-free adsorption process in an oxygen concentration unit 3 and supplying it with the required flow rate to the latter inlet. This allows you to do with a simpler air purification system.

The main characteristics of compressor 6: maximum pressure 10 bar, temperature at the outlet valve 40 ° C, power at a maximum working pressure of 1.5 kW, motor shaft speed of 1500 rpm, maximum sound pressure level of 82 dBA.

As a filter in block 2 of air compression is used separation and filtering module SFM-20. Compressed air enters through the side nozzle into the first filter 8, where in the space between the filter element 25 and the housing, the largest drops of liquid are separated. The separated liquid flows down the housing wall to the lower part of the filter 8. Next, air, together with small particles, enters the outer surface of the filter element 25 and passes through the filter layer, where up to 90% of solid and liquid particles are captured. In the second stage, the final cleaning of compressed air takes place. The separated liquid flows down the outer mesh casing to the lower part of the filter housing 8. The accumulated separated liquid is periodically removed from the filters through drain valves. The presence of large drops of water at the outlet of the separation-filtration module is completely excluded, the quality of cleaning compressed air from drops larger than 0.1 microns is 95%. Therefore, in the air entering at a flow rate of 0.34 nm ³ / min to the inlet of the oxygen concentration unit 3 at the optimum operating pressure (0.5-0.8) mPa, only that droplet moisture which is condensed in the supply pipe can be contained.

During operation of an autonomous mobile complex of technical support with oxygen for the operation and resuscitation department, the following measured technical parameters are subjected to instrument control: GHS pressure, oxygen concentration in the GHS, compressor outlet pressure 6 (no more than 0.8 MPa), pressure drop across the first filter system 7 (not more than 0.1 MPa). For visual monitoring of the GHS pressure on the panel of the oxygen concentration unit 3, there is a 24 MTM-2K 16/10 B manometer with limits of 0.4-0.6 MPa.

For visual monitoring of the oxygen concentration in the GHS, the complex includes a gas analyzer 15 of the PGK-6 type with limits for measuring the volume fraction of oxygen from 0 to 100% and a measurement accuracy of + -1%. The magnitude of the controlled concentration is in the range from 90 to 93%. The gas analyzer 15 is equipped with sound and light alarm minimum and maximum oxygen content in the GHS.

The energy module 19 provides power to the compression unit 2 and the oxygen concentration unit 3 with a single-phase alternating current voltage of 220 V, a frequency of 50 Hz with a selected power of 2000 VA by the first and 250 VA by the second unit. The on-board thermochemical oxygen generator 33 is part of an autonomous complex providing oxygen to the victims and is intended for use on board automobile, including armored, towing vehicles instead of standard high-pressure oxygen cylinders as an oxygen source when working with wearable devices IVM 20, IK 21, IN 22 The generator 33 is used to produce oxygen from solid oxygen-containing chemical compositions (TCCS) by their decomposition in a self-sustaining chemical reaction ii. It is designed for the use of TCCC in the form of single-use monoblocks (checkers), providing a specific oxygen output of at least 0.36 kg (250 nl) from 1 kg of TCCC. The generator 33 without equipment provides a continuous supply of oxygen with a pressure of 0.2-0.4 MPa for 15 min with a forced flow rate of 20 nl / min, when re-loaded with a continuous supply of oxygen for 2 hours with an average flow rate of 10 nl / min. The quality of the oxygen produced complies with the requirements of GOST 5583-78.

The reactor 28 is a high-pressure chamber, consisting of a base and a cylindrical glass. At the base of the reactor 28, mounted to the body of the generator 33, there is a heating element designed to initiate a thermochemical reaction and two filters 27.29 for cleaning the produced oxygen from dust particles resulting from the reaction. The base and the beaker of the reactor 28 are connected through a sealing ring using a quick-release clamp. To prevent the contact of surrounding objects and maintenance personnel with the outer surface of the reactor 28, which can reach a temperature of 93 degrees Celsius during the reaction, a protective casing is provided in the form of a cylindrical cup fixed to the generator body 33 and having a perforated surface. To cool the oxygen coming from the reactor 28 into the gas system, a heat exchanger 31 is provided, made in the form of a coil made of a stainless steel tube placed in a tank filled with an alcohol-water mixture. Additional purification of oxygen from possible impurities is achieved using an output filter 32 of fine cleaning, installed after the heat exchanger 31 and made in the form of a cylindrical tank filled with filtering material, which includes kaolin cotton wool, silica gel and fibrous filtering material FPP. On the front panel of the generator 33, instruments and controls are installed, including an electric switch, an oxygen reducer 36 of the type BKO-50-12.5, valve 34, and sound and light indicators. The generator 33 is provided with an audible alarm announcing the achievement of the lower permissible value of the oxygen pressure with a pulse frequency of 1000 Hz. To signal the readiness of the generator 33 for operation (green indicator) and the operation of the heating element in the reactor 28 (yellow indicator), optical signaling devices are used.

To turn on the concentration unit 3, it must be connected to a source of compressed air, for which purpose connect the supply pipe to fitting Ш1 and apply electric power to it from the network 47 220 V, 50 Hz and compressed air. To do this, click the "Network" button and the "Start" button on the panel of the concentration unit 3. Wait 2-3 minutes, after which block 3 is ready for operation. To supply the GHS to the consumer, it is enough to open the valve 13-1.

If it is necessary to control the oxygen content at the output of the concentration unit 3, it is necessary to connect a flexible tube from the gas analyzer 15 PGK-6 to the fitting Ш3, open the valve 13-2, turn on the gas analyzer 15 power supply network 47 and measure the oxygen concentration. To supply compressed air to the inlet of the concentration unit 3 from the individual air compression unit 2, the following operations must be carried out: connecting the individual air compression unit 2 to the power supply using the cable included in its kit; apply power to the input of the individual air compression unit 2 and press the "start" button on its console. In the process, it is necessary to periodically (at least 1 time per hour) drain the condensate from the filters 8 of the individual air compression unit 2, periodically monitor the pressure at the compressor outlet and the pressure drop across the filters 8. The oxygen generated in the reactor 28 of the generator 33, after cooling and cleaning is collected in a cylinder of 40 with a capacity of 2 liters. The non-return valve 11a, installed in the upper part of the fine filter 32, prevents the flow of oxygen from the cylinder 40 into the reactor 28. In order to avoid exceeding the oxygen pressure in the generator 33 during the thermochemical reaction, the safety valve 26 is installed on the reactor 28, which is configured for a response pressure of 15 MPa. The pressure monitoring device 41 is designed to control the operation of the heating element located at the base of the reactor 28 during the thermochemical reaction.

To enter the generator 33 into operation at the place of operation (figure 2, 3) it is necessary to remove the protective cover. Open the oxygen pressure relief valve 30 located on the front of the generator 33; remove the clamp and disconnect the cylindrical glass of the reactor 28. Open the sealed package with interchangeable checkers-reactors 28 using a special key; remove the reactor 28, observing safety rules when working with pure oxygen, and install the base of the reactor 28 on the pin. Install the reactor cup 28 and secure it with a clamp to the base; close the oxygen pressure relief valve 30. Close the high pressure oxygen outlet valve 34, unscrew the regulating flywheel of the gearbox until the master spring is completely released. Connect generator 33 to a power source (24 V DC). The heating element in the reactor 28 is turned on by a toggle switch located on the front panel of the generator 33; the heating on time is set by the timer of the pressure control device of the control unit 41 of the generator 33. The oxygen released by the reactors 28 as a result of the thermochemical reaction enters the cylinder 40 through the purification and cooling systems. The oxygen is taken by consumers 12, depending on the purpose, from high fittings (through valve 34) or low (through gear 36) pressure. At the end of the working cycle, it is necessary to remove the spent reactor 28 using the above-described working methods and observing safety measures when in contact with surfaces having a high temperature. The spent reactors 28 are stored in the protective cover of the generator 33 until subsequent disposal. If necessary, the generator 33 is re-loaded.

To turn off the concentration unit 3, it is necessary to close the first and second valves 13-1, 13-2, press the stop button on the panel of the concentration unit 3, wait for the control indicators for the control unit 5 to turn off, turn off the power by pressing the network button, and turn off the compressed supply air and power.

To turn off the air compression unit 2, press the "stop" button on the compressor console to turn it off, disconnect the supply pipe from the concentration unit 3.

Standard cylinders with a capacity of 2 l, which are currently used in inhalers and ventilators, require oxygen re-charging as oxygen is consumed, which in practice is carried out using standard cylinders with a capacity of 40 l and a working pressure of 15 MPa. Oxygen cylinders during storage, transportation and operation require protection from shock, heat, bullets, splinters and other factors, the impact of each of which can cause an explosion. Transportation by rail requires special conditions (like explosive goods), transportation is prohibited by aviation. Additional difficulties and, consequently, costs arise when transporting used cylinders to oxygen filling stations. The transportation, storage and operation of generators 33, as well as checkers 28, which are in sealed containers, are devoid of many of these disadvantages. The checker withstands heating up to 300 degrees Celsius, it is assumed that a direct hit by a bullet or a fragment will only lead to its destruction. To produce oxygen, equal to the volume contained in the cylinder (6000 sludge), 20 pieces are required. The volume they occupy is approximately 4 times less than that of cylinders. In quantitative terms, the possibility of transporting oxygen in checkers is also 4 times greater than in standard cylinders used. Even taking into account the volume occupied by the generator 33-41, 48 cubic meters. dm, the advantage of using a cylinder is apparent, since the contents of 200 standard oxygen cylinders (each with a capacity of 40 l) are required to fulfill a given operating time, not to mention the above difficulties associated with their operation in a military environment. A comparison of the mass data also shows the advantage of using a generator 33 and a reactor 28: already at the initial application, the sum of the masses of the generator 22 kg and the reactors is also 22 kg is much less than the mass of the specified standard cylinder.

Thus, the claimed autonomous complex Grishin-Logunov-Litvinov-Ushakov-Medvedev providing oxygen to the victims in the operational resuscitation departments allows to eliminate almost all the disadvantages of the prototype device, thereby increasing the efficiency of the technical support of the operation resuscitation departments by expanding the functionality complex by increasing the mobility, safety and productivity of oxygen, improving control and management of the supply process with a vent of artificial lung ventilation, oxygen inhalation and inhalation anesthesia during their operation.
