[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] In the following detailed description, reference may be made to the various specification drawings that are part of the present application and are used to illustrate specific embodiments of the present application. In the accompanying drawings, similar reference numerals describe substantially similar components in different figures. The various specific embodiments of the present application are described below in sufficient detail so that a person of ordinary skill in the art with relevant knowledge and skills in the art can implement the technical solutions of the present application. It should be understood that other embodiments may also be used or structural, logical or electrical changes may be made to the embodiments of the present application.

[0023] In view of the technical problems existing in the prior art, the present application proposes a method for preparing gas for breathing training. The method is based on a breathing training device, such as Figure 1 shown.

[0024] The device includes: an air supply unit 11, a nitrogen and oxygen separation unit 12, a main control unit 13, an oxygen detection unit 14 and a three-way valve 15. The main control unit is used to control the working states of the air supply unit 11, the nitrogen and oxygen separation unit 12 and the three-way valve 15. The air supply unit 11 is used to provide compressed air. The nitrogen and oxygen separation unit 12 is connected to the air supply unit 11, and is used to prepare nitrogen or oxygen using compressed air to adjust the ratio of nitrogen and oxygen in the output gas to form low-oxygen gas or oxygen-rich gas. The low-oxygen gas is output to the low-oxygen pipeline 16 through the three-way valve 15, and the oxygen-rich gas is output to the oxygen-rich pipeline 17 through the three-way valve 15. The oxygen detection unit 14 is arranged on the pipeline through which the output gas of the nitrogen and oxygen separation unit 12 flows, and is used to detect the oxygen concentration of the output gas and feed it back to the main control unit 11.

[0025] Based on the above device, the gas preparation method for breathing training includes:

[0026] S11: After the user sets the working mode and oxygen concentration, the main control unit 11 controls the air supply unit 12 to turn on and generate compressed air.

[0027] S12: The main control unit 11 controls the nitrogen-oxygen separation unit 13 to generate gas with a corresponding oxygen concentration using compressed air.

[0028] S13 : the oxygen detection unit 14 detects the oxygen concentration of the gas output by the nitrogen and oxygen separation unit 13 , and feeds back the concentration to the main control unit 11 .

[0029] S14 : the main control unit 11 controls the three-way valve 15 to connect the gas outlet of the nitrogen and oxygen separation unit 13 to the low oxygen pipeline 16 or the oxygen-rich pipeline 17 based on whether the user selects the low oxygen mode or the oxygen-rich mode.

[0030] If the oxygen concentration of the gas output by the nitrogen and oxygen separation unit 13 does not meet the set oxygen concentration, the main control unit controls the gas in the low oxygen pipeline or the oxygen-rich pipeline to be discharged into the atmosphere. If the oxygen concentration of the gas output by the nitrogen and oxygen separation unit meets the set oxygen concentration, the main control unit controls the gas in the low oxygen pipeline or the oxygen-rich pipeline to be output to the user device for use.

[0031] The gas preparation method for breathing training proposed in this application integrates the hypoxic function and the oxygen-enriched function into the same device through integrated integration, and prepares hypoxic gas or oxygen-enriched gas through a set of preparation methods. This application can simultaneously meet the needs of simulated plateau altitude training and hypoxic (oxygen-enriched) training, with high control accuracy, high integration, small size and high convenience. And this method can quickly and conveniently produce hypoxic gas.

[0032] In some embodiments, the compressed air is passed into the nitrogen and oxygen separation unit after being deoiled, dehydrated and dusted.

[0033] This application can purify and filter compressed air, which can ensure the safety of users inhaling gas on the one hand, and extend the service life of the equipment on the other hand.

[0034] In some embodiments, after the user selects the hypoxic mode, the oxygen concentration of the output gas is adjusted by setting the altitude to be simulated, wherein the oxygen concentration corresponds to the oxygen concentration at the altitude to be simulated.

[0035] When using the hypoxic mode, users often want to simulate training at a certain altitude. Therefore, it is more intuitive and convenient to adjust the oxygen content by adjusting the altitude. This application will pre-store the correspondence between altitude and oxygen content in the device, and directly output the gas with the corresponding oxygen concentration after the user adjusts the altitude.

[0036] In some embodiments, the altitude adjustment range is 1000-6000m, and the adjustment accuracy is ±100m.

[0037] The hypoxia mode of the present application has a large adjustment range and high adjustment accuracy.

[0038] In some embodiments, in the oxygen-rich mode, the oxygen concentration adjustment range is 21%-40%, and the oxygen content adjustment accuracy is ±0.2%.

[0039] The oxygen-rich mode of the present application has a large adjustment range and high adjustment accuracy.

[0040] In some embodiments, the breathing training device further includes a gas volume regulating valve, and the main control module controls the gas volume regulating valve to adjust the purity and flow of the output gas.

[0041] In addition to adjusting the oxygen concentration, the purity and flow of the output gas can also be adjusted through the gas volume control valve, making the simulation more controllable and realistic.

[0042] In some embodiments, the output gas flow rate is adjusted in the range of 5-40 ml / min.

[0043] This application has a wide range of gas volume adjustment.

[0044] In some embodiments, the amount of gas produced and provided by the gas supply unit is 1.05 to 1.3 times the amount of raw gas required for the output gas.

[0045] The gas supply unit of the present application can ensure the long-term use of the equipment and provide a steady supply of gas.

[0046] In some embodiments, the breathing training device further comprises an alarm unit, which generates an alarm when a system failure occurs in the breathing training device, the alarm extension time is exceeded, or the filter fails.

[0047] The application can also monitor the operating status of the equipment and issue an alarm when a system failure occurs, the warning extension time is exceeded, or the filter fails.

[0048] In some embodiments, the user device comprises a breathing mask or a small airtight enclosure.

[0049] The present application uses a wide range of equipment, which can be a breathing mask or a small airtight enclosure.

[0050] In some embodiments, the breathing training device further includes a pipeline pressure detection unit and an exhaust unit, wherein the pipeline pressure detection unit detects the pressure of the gas pipeline. When the gas pipeline pressure is greater than the preset air pressure, the main control unit controls the opening of the exhaust unit to discharge the gas in the pipeline into the atmosphere until the gas pipeline pressure is less than the preset air pressure.

[0051] The gas pipeline can refer to the path through which any gas flows. Excessive pressure in the gas pipeline will affect the simulation effect of the device and also affect the service life of the device.

[0052] The following is an explanation through a specific embodiment.

[0053] When a user wants to perform hypoxia training, the operating mode of the device can be set to hypoxia mode through the main control module 11. In some embodiments, the main control module 11 may include a touch display, and the user can select and set functions through touch. At the same time, the device operation information or alarm information can be displayed on the screen during the training process.

[0054] Then, the altitude and output gas flow can be set.

[0055] After the system starts running, the gas supply unit 12 starts and outputs compressed gas. The compressed gas will be deoiled, dehydrated, and dusted. After the treated compressed gas enters the nitrogen-oxygen separation unit 13, the main control unit 11 will call the corresponding oxygen content based on the altitude, and control the nitrogen-oxygen separation unit 13 to produce nitrogen to output gas with the corresponding oxygen content. In some embodiments, the nitrogen-oxygen separation unit 13 is a nitrogen-oxygen separation device having a hollow fiber membrane group.

[0056] The gas output by the nitrogen and oxygen separation unit 13 flows through the oxygen detection unit 14, and the oxygen detection unit 14 feeds back the oxygen concentration in the current gas to the main control module 11. In some embodiments, the oxygen detection unit 14 can be arranged at the gas outlet of the nitrogen and oxygen separation unit 13, or can be arranged on the low oxygen pipeline 16 and the oxygen-rich pipeline 17.

[0057] If the oxygen concentration of the gas output by the nitrogen and oxygen separation unit 13 does not meet the set oxygen concentration, the main control unit 11 controls the gas in the low oxygen pipeline or the oxygen-enriched pipeline to be discharged into the atmosphere. If the oxygen concentration of the gas output by the nitrogen and oxygen separation unit 13 meets the set oxygen concentration, the main control unit 11 controls the gas in the low oxygen pipeline or the oxygen-enriched pipeline to be output to the user device for use.

[0058] When the user selects the oxygen-rich mode, the nitrogen-oxygen separation unit 13 generates oxygen and outputs oxygen-rich gas in a similar working manner.

[0059] In some embodiments, if the output gas flow rate changes during use, the manual gas volume regulating valve needs to be adjusted to the required gas volume.

[0060] In some embodiments, if the simulated altitude or oxygen concentration changes during use, the altitude or oxygen concentration is adjusted again.

[0061] In order to increase the reliability of the product, the device is equipped with maintenance reminder and alarm function. When the device has system failure, exceeds the warning extension time or the filter fails, the touch screen will show an alarm prompt. When the filter element working time reaches the warning replacement time, the touch screen will show the filter replacement prompt.

[0062] In some embodiments, when the pressure of the gas pipeline is greater than 0.95 MPa (settable), the system controls the drain valve to open, and when the pressure drops below 0.9 MPa (settable), the drain valve is closed.

[0063] In some embodiments, the total power consumption of the device system is ≤1 kW.

[0064] The present application can adjust the oxygen concentration by controlling the purity regulating valve. Table 1 shows the corresponding oxygen concentration and altitude under different purity regulating valve pressures.

[0065] Table 1

[0066]

[0067]

[0068] As shown in Table 1, the present application has a large adjustable range, high adjustment accuracy, and accurate control of oxygen content.

[0069] The above embodiments are only used to illustrate the present application, and are not intended to limit the present application. Ordinary technicians in the relevant technical field may make various changes and modifications without departing from the scope of the present application. Therefore, all equivalent technical solutions should also fall within the scope disclosed in the present application.
