[0051] The present application provides a high and low oxygen control device, the device comprising:

[0052] Air production module, air processing module, high and low oxygen separation module, output module and control module;

[0053] The air production module, the air treatment module, the high-low oxygen separation module and the output module are connected in sequence; the air production module is used to produce air, the air treatment module is used to pre-treat the produced air, the high-low oxygen separation module is used to separate the pre-treated air into high-oxygen air and low-oxygen air, the high-low oxygen separation module includes a high-oxygen branch and a low-oxygen branch, the control module is used to control the gas transmission ratio of the high-oxygen branch and the low-oxygen branch, and the output module is used to output the regulated high-oxygen and low-oxygen air.

[0054] Here, the high and low oxygen control device realizes precise control of the oxygen concentration in the air through the coordinated work of multiple modules, thereby meeting the specific requirements of oxygen concentration in different application scenarios.

[0055] The air production module is responsible for generating the initial air flow, directly extracting air from the external environment, or generating compressed air through mechanical means (such as a compressor). The air processing module pre-processes the air from the air production module, including but not limited to adjusting the temperature, humidity, removing specific gas components (such as carbon dioxide, nitrogen, etc.), etc., to ensure the efficiency and effect of the subsequent separation process. The high and low oxygen separation module uses physical or chemical methods (such as molecular sieves, membrane separation, pressure swing adsorption, etc.) to separate the pre-treated air into high oxygen air and low oxygen air. The module includes a high oxygen branch and a low oxygen branch, which output oxygen-rich and oxygen-poor air respectively. The control module monitors the working status of each module and the concentration of the output gas through sensors, and adjusts the gas transmission ratio of the high and low oxygen branches according to preset parameters or external instructions to achieve precise control of the oxygen concentration. The output module outputs the regulated high oxygen air and low oxygen air to the required application scenarios respectively.

[0056] In some embodiments, the air production module is an air compressor, the air inlet of the air compressor is connected to an air source, and the output end of the air compressor is connected to the input end of the air processing module.

[0057] See also Figure 1The air inlet of the air compressor is usually designed to be open so that air can be sucked in from the surrounding environment or a specific air source (such as a pipeline air supply system). This air source can be the atmosphere in the natural environment, or it can be air that has been preliminarily treated to ensure the quality of the air input to the air compressor. After the air compressor compresses the inhaled air, it delivers the compressed air to the subsequent processing module through its output end (usually a pressure outlet). In an embodiment of the present application, the output end is directly connected to the input end of the air treatment module so that the compressed air can be further pre-processed.

[0058] In some embodiments, the air processing module includes a heat exchanger, an air filter, and a combined filter;

[0059] The heat exchanger is used to cool the air produced by the air production module, the air filter is used to filter the first particles in the cooled air, the combined filter is used to separate oil from water and filter the second particles in the cooled air, and the diameter of the first particles is greater than the diameter of the second particles;

[0060] The heat exchanger, the air filter and the combined filter are connected in sequence, the input end of the heat exchanger is connected to the output end of the air production module, and the output end of the combined filter is connected to the input end of the high-low oxygen separation module.

[0061] Please continue to see Figure 1, the air treatment module includes three main components: heat exchanger, air filter and combined filter. This design ensures that the compressed air output from the air production module (i.e., air compressor) can be fully pre-treated to meet the air quality requirements of the subsequent high and low oxygen separation module. The main function of the heat exchanger is to cool the compressed air output from the air production module. Since the air compressor compresses the air during operation, this process is often accompanied by an increase in temperature. High-temperature air may not only affect the performance of subsequent filters, but may also have an adverse effect on the high and low oxygen separation module. Therefore, reducing the air temperature to an appropriate range through a heat exchanger is an important step to ensure the stable operation of the entire system. The air after the air filter cools down then enters the air filter for the first particle filtration. This step is to remove larger particles in the air, such as dust, sand, etc. If these particles enter the subsequent processing links, they may cause wear or blockage to the equipment, affecting the overall performance of the system. The combined filter further performs oil-water separation and second particle filtration on the air. The air compressor may generate a certain amount of oil mist and water vapor during operation. If these oil-water mixtures are not treated, they will seriously affect the separation effect of the high and low oxygen separation modules and the quality of the output air. The combined filter can effectively separate the oil-water mixture from the air and remove finer particles at the same time through its special structure and material. These finer particles are smaller in diameter than those that can be removed by the air filter, so they need to be further filtered through the combined filter.

[0062] The workflow of the entire air handling module is as follows:

[0063] Cooling treatment: The compressed air output from the air production module (air compressor) first enters the heat exchanger for cooling treatment.

[0064] First particle filtration: The cooled air enters the air filter for first particle filtration to remove larger particles.

[0065] Oil-water separation and secondary particle filtration: The air that has undergone preliminary filtration then enters the combined filter for oil-water separation and secondary particle filtration to ensure that the air quality meets the requirements of subsequent processing links.

[0066] Output to the high and low oxygen separation module: Finally, the fully pre-treated air flows out from the output end of the combined filter and enters the high and low oxygen separation module for further separation processing.

[0067] The above method ensures that every link from air production to high and low oxygen separation can operate stably and efficiently, thereby providing users with high-quality and high-reliability high and low oxygen control services.

[0068] In some embodiments, the high-low oxygen separation module further includes a nitrogen module, which is used to separate the pretreated air into high-oxygen air and low-oxygen air, and the input end of the nitrogen module is connected to the output end of the air treatment module, and the output end of the nitrogen module is respectively connected to the high-oxygen branch and the low-oxygen branch;

[0069] The high oxygen branch includes a first three-way valve, and the low oxygen branch includes a second three-way valve, wherein a first end of the first three-way valve is respectively connected to an output end of the high oxygen branch and an output end of the low oxygen branch, and a first end of the second three-way valve is connected to an output end of the low oxygen branch;

[0070] The output module includes an output branch and an exhaust branch. The second end of the second three-way valve is connected in parallel with the second end of the first three-way valve and then connected to the input end of the output branch. The third end of the second three-way valve is connected in parallel with the third end of the first three-way valve and then connected to the input end of the exhaust branch.

[0071] Please continue to see Figure 1 , the high-low oxygen separation module is expanded to include a nitrogen module, which uses nitrogen (or other inert gases) as a carrier or diluent in the high-low oxygen separation module to separate the pre-treated air into high-oxygen air and low-oxygen air through a specific separation mechanism (such as pressure swing adsorption, membrane separation, etc.). This process may require precise control of parameters such as nitrogen flow, pressure and temperature to ensure that the separation effect meets the predetermined requirements.

[0072] The input end of the nitrogen module is connected to the output end of the air treatment module to receive fully pre-treated air. Its output end is connected to the high oxygen branch and the low oxygen branch respectively, and the separated high oxygen air and low oxygen air are transported to these two branches respectively (in Figure 1 O2 is used to represent high-oxygen air, and N2 is used to represent low-oxygen air).

[0073] The first three-way valve and the second three-way valve are used to control the gas flow direction in the high oxygen branch and the low oxygen branch respectively. The first end of the first three-way valve is connected to the output end of the high oxygen branch and the output end of the low oxygen branch (for gas mixing in some cases), and the second three-way valve directly controls the gas flow direction in the low oxygen branch.

[0074] By adjusting the switching state of the three-way valve, the system can flexibly change the flow direction and proportion of high-oxygen air and low-oxygen air to meet the needs of different application scenarios.

[0075] The output module includes at least one output branch for outputting the regulated high oxygen air or low oxygen air to the required application scenario. At the same time, an exhaust branch is also provided for discharging unnecessary gas in the system. The second end and the third end of the second three-way valve and the first three-way valve are connected in parallel to the output branch and the exhaust branch respectively. This design allows the system to choose to output the gas to the outside or discharge it to the exhaust branch as needed.

[0076] In some embodiments, the first end of the second three-way valve is connected to the output end of the hypoxia branch through a speed regulating valve and a first proportional valve connected in parallel;

[0077] The first end of the first three-way valve is communicated with the output end of the low oxygen branch through a second proportional valve.

[0078] A speed regulating valve, a first proportional valve and a second proportional valve are introduced here. The addition of these components makes the system's control over gas flow more precise and flexible.

[0079] The first end of the second three-way valve is connected to the output end of the hypoxia branch through the speed regulating valve and the first proportional valve in parallel. This parallel design allows the system to use the speed regulating valve to roughly adjust the gas flow (by changing the valve opening to adjust the flow), and use the first proportional valve to finely adjust (by changing the proportional coefficient of the valve to accurately control the flow).

[0080] The second end and the third end of the second three-way valve: As mentioned above, these two ports are connected in parallel to the output branch and the exhaust branch respectively, so as to control the output or discharge of hypoxic air.

[0081] The first end of the first three-way valve is connected to the output end of the low oxygen branch through the second proportional valve. Here, the second proportional valve is used to adjust the gas flow from the low oxygen branch to the high oxygen branch (or possible mixing / reflow path). Its working principle is similar to that of the first proportional valve.

[0082] Specifically, in the embodiment of the present application, 9-16% is low oxygen, 17-24% is normal mode, and 25-36% is high oxygen.

[0083] In the hypoxic mode, the second proportional valve (proportional valve 2) does not work, the first end and the third end of the first three-way valve (three-way valve 1) are connected, the first end and the second end of the second three-way valve (three-way valve 2) are connected, the three-way valve 1 exhausts, and the three-way valve 2 outputs.

[0084] In the normal mode, it is divided into below 21% and 21% and above. When below 21%, it is the same as the hypoxic mode, the difference is that the first end and the second end of the three-way valve 1 are connected, and the three-way valve 1 and the three-way valve 2 are both connected.

[0085] When the pressure is 21% or above, the first and third ends of three-way valve 2 are connected, three-way valve 2 exhausts, and three-way valve 1 outputs. If proportional valve 2 does not work, high oxygen above 36% is output. High oxygen mode is similar to 21% or above, the difference is whether proportional valve 2 works.

[0086] The above method enables the high-low oxygen separation module to more accurately control the generation ratio and flow rate of high-oxygen air and low-oxygen air. By adjusting the opening or proportional coefficient of the speed regulating valve, the first proportional valve and the second proportional valve, the system can flexibly adapt to the requirements of oxygen concentration in different application scenarios.

[0087] In some embodiments, the filter branch in the air processing module is connected to the exhaust branch through a solenoid valve, the exhaust branch includes an atomizer, and the exhaust branch is used to discharge exhaust gas.

[0088] The filter branch in the air handling module is designed to be connected to the exhaust branch through a solenoid valve, and the exhaust branch also contains an atomizer. This design increases the flexibility and functionality of the system, especially in treating exhaust gas and reducing environmental pollution.

[0089] The solenoid valve is installed between the filter branch and the exhaust branch as a control element. By controlling the on / off state of the solenoid valve, it is possible to flexibly control whether the filtered exhaust gas enters the exhaust branch for discharge. This design enables the system to discharge the exhaust gas directly into the environment when necessary, or to suspend the discharge for further treatment or recycling when necessary.

[0090] The atomizer is installed in the exhaust branch. Its function is to mix the exhaust gas with an appropriate amount of water or other liquid to form tiny droplets or aerosols. This process helps to reduce the concentration of harmful substances in the exhaust gas and reduce its pollution to the environment. At the same time, the atomization treatment can also increase the humidity of the exhaust gas, which helps to reduce the flying of dust and other particulate matter.

[0091] The exhaust branch here can be used for exhaust under high and low oxygen control, and can also cooperate with the air treatment module to discharge filtered gas, saving hardware costs.

[0092] In some embodiments, the output module includes:

[0093] An exhalation valve, a humidifier, a first virus filter, an air bag, a second virus filter and a breathing mask are connected in sequence, and the input end of the exhalation valve is connected to the output end of the high and low oxygen separation module.

[0094] Please continue to see Figure 1The exhalation valve is located at the front end of the output module, and its input end is connected to the output end of the high and low oxygen separation module. Its main function is to control the flow direction of the gas to ensure that the gas can be smoothly discharged from the system during exhalation to avoid mixing with the inhaled gas. Humidifier.

[0095] The humidifier is located right after the exhalation valve. Its function is to humidify the dry gas after being processed by the high and low oxygen separation module. The moist air helps reduce dryness and discomfort in the respiratory tract and improves breathing comfort.

[0096] The main function of the first virus filter is to filter out viruses, bacteria and other microorganisms that may exist in the gas. It is made of high-efficiency filter materials and can effectively prevent microorganisms from entering the human body through the respiratory system.

[0097] The airbag is usually located after the virus filter, and its function is to provide a certain degree of elasticity and cushioning during breathing. It can expand and contract accordingly according to the user's breathing strength and frequency, thus ensuring smooth and comfortable breathing.

[0098] The second virus filter is similar to the first virus filter. The second virus filter is also used to filter microorganisms in the gas. Its setting can be regarded as a supplement and reinforcement of the first virus filter to further ensure the cleanliness of the output gas.

[0099] The breathing mask is the final endpoint of the entire output module, which directly contacts the user's face and provides a channel for breathing gas.

[0100] The various components in the above output modules cooperate with each other and perform their respective functions, jointly ensuring that the breathing gas ultimately provided to the user is both safe and comfortable.

[0101] In some embodiments, the apparatus further comprises:

[0102] A pressure sensor is arranged between the air production module and the air processing module, an NTC sensor is arranged in the air processing module, a gas pressure relief valve is arranged between the air processing module and the high and low oxygen separation module, an oxygen concentration sensor and a differential pressure sensor are arranged in the output module, and the signal output ends of the pressure sensor, the NTC sensor, the oxygen concentration sensor and the differential pressure sensor are respectively connected to the control module.

[0103] Here, the device is further expanded to include multiple sensors and valves to enable precise monitoring and control of system operation. These additional components not only improve the safety and reliability of the system, but also enhance its intelligence and automation. The following is a detailed analysis of these components and their functions:

[0104] The pressure sensor is installed between the air production module and the air treatment module. It monitors and measures the air pressure before entering the air treatment module. This is essential to ensure stable operation of the system and prevent failures caused by abnormal pressure. Its signal output end is connected to the control module, and the pressure data is transmitted to the control module in real time for processing and analysis.

[0105] The NTC sensor is installed in the air handling module. The NTC (Negative Temperature Coefficient) sensor is used to monitor the temperature inside the air handling module. By measuring the temperature, it can be determined whether the system is in normal working condition and whether the cooling or heating equipment needs to be adjusted to maintain a suitable working temperature. Its signal output end is also connected to the control module to realize real-time monitoring and control of temperature.

[0106] The gas pressure relief valve is set between the air handling module and the high and low oxygen separation module. When the internal pressure of the system exceeds the set threshold, the gas pressure relief valve will automatically open and release excess gas to protect the system from damage. This is one of the important measures to ensure the safety of the system. It is usually designed to be automatically controlled and can respond quickly to abnormal pressure without human intervention.

[0107] The oxygen concentration sensor is set in the output module. It monitors and measures the oxygen concentration in the breathing gas output to the user. This is one of the key indicators for evaluating system performance and is directly related to the user's treatment effect and safety. Its signal output end is connected to the control module, and the oxygen concentration data is transmitted to the control module in real time for display and recording.

[0108] The differential pressure sensor is also set in the output module. It is used to monitor the tightness between the breathing mask or airbag and the user's face. By measuring the pressure difference between the inside and outside of the mask, it can be determined whether there is leakage, thereby ensuring that the user can get enough oxygen supply. Its signal output end is connected to the control module to achieve real-time monitoring and alarm of tightness.

[0109] As the "brain" of the system, the control module is responsible for receiving signals from various sensors and processing and making decisions based on preset algorithms and logic. It can control the switch of solenoid valves, adjust gas flow, monitor system status, etc. to ensure that the system is always in the best working condition.

[0110] In summary, these newly added sensors and valves, through close cooperation with the control module, together form a highly intelligent and automated breathing system. They not only improve the safety and reliability of the system, but also provide users with a more comfortable and personalized breathing experience.

[0111] In some embodiments, the device further comprises: a human body function acquisition module, the human body function acquisition module is used to acquire human body function information, and a signal output end of the human body function acquisition module is connected to a signal input end of the control module.

[0112] Here, the human body function acquisition module is mainly used to collect the user's real-time human body function information, including but not limited to key physiological indicators such as heart rate, respiratory rate, blood oxygen saturation, and body temperature. This information is of great significance for assessing the user's health status, adjusting respiratory treatment parameters, and preventing potential health risks. The human body function acquisition module can include a variety of sensors, such as heart rate sensors, respiratory sensors, blood oxygen saturation sensors, and temperature sensors. These sensors collect the user's physiological data in a non-invasive manner (such as through skin contact or wearing on a specific part). The collected human body function information will be transmitted to the control module in real time. This is usually done by wired or wireless means, such as Bluetooth, Wi-Fi or other low-power wireless communication technologies. Ensuring accurate and fast data transmission is the key to ensuring the system response speed and treatment effect. The signal output end of the human body function acquisition module is connected to the signal input end of the control module to form a closed-loop control system. After receiving the human body function information, the control module will perform real-time analysis and processing, and adjust the operating parameters of the ventilator (such as oxygen concentration, flow, pressure, etc.) according to the preset algorithm and logic to meet the user's personalized needs. Through the human body function acquisition module, the system can monitor the user's physiological changes in real time and automatically adjust the treatment plan according to these changes. This personalized treatment mode can significantly improve the treatment effect, reduce unnecessary medical interventions, and improve the user's comfort and satisfaction. In addition to playing a role in the treatment process, the human body function acquisition module can also be used for the user's daily health monitoring. When the user's physiological indicators are detected to be abnormal, the system can promptly issue an early warning to the user.

[0113] The present application also provides a method for regulating high and low oxygen, characterized in that the method comprises:

[0114] Collect human function information of target personnel through high and low oxygen control devices;

[0115] Determining a high-low oxygen control strategy based on the human body function information, and controlling the high-low oxygen control device to perform high-low oxygen training according to the high-low oxygen control strategy;

[0116] The method further comprises:

[0117] When the human body function information is abnormal or the operating parameters of the high and low oxygen control device are abnormal, an alarm is issued;

[0118] The method further comprises:

[0119] Detecting gas parameters of the current gas, wherein the gas parameters include temperature and oxygen concentration;

[0120] The high and low oxygen control device is controlled to adjust the current gas based on the preset parameters and the gas parameters.

[0121] See also Figure 2 , Figure 2 This is one of the flow charts of the high and low oxygen control method provided in the embodiment of the present application, such as Figure 2 As mentioned above, after the device is turned on, it first collects information such as pressure, blood oxygen, pulse rate, and respiratory rate of the patient. When the blood oxygen value is lower than the set protection value, high oxygen is injected through the device. When the blood oxygen value is greater than the set protection value, the original training state is restored, and it stops when the detection cycle ends. This process also includes abnormal detection. When the pressure is lower or higher than the limit value after running for 5s, an alarm is issued; after running for a set time, an alarm will also be issued if the oxygen concentration exceeds the limit; the user's respiratory rate and pulse rate exceeding the limit will also trigger an alarm.

[0122] See also Figure 3 , Figure 3 This is the second flow chart of the high and low oxygen control method provided in the embodiment of the present application, such as Figure 3 As shown, the user can obtain training parameters through the interactive module, automatically match the oxygen concentration and gas temperature according to the altitude, obtain the training oxygen concentration and the set temperature of the output gas, and start the training after the user's vital signs data are normal.

[0123] During the training process, if it is the first run, the first function coefficient (the default coefficient set at the factory) is called. During the running process, the first coefficient will be adjusted to make the system more accurate. When the error is less than the set error value, the second coefficient can be determined and saved. If it is not the first run, the second coefficient is called directly.

[0124] After entering the periodic timing, the system will obtain the current gas oxygen concentration. The system defaults to set the absolute value of the difference between the oxygen concentration and the current oxygen concentration to be less than or equal to 0.2, and keep the duty cycle unchanged, so that the current duty cycle parameter can be saved as the second function coefficient, and then enter the next periodic timing. When the absolute value of the difference between the set oxygen and the current oxygen concentration is greater than 0.2 and less than or equal to 0.5, if the set oxygen is less than the current oxygen, the duty cycle will increase by 3%, and if the set oxygen is greater than the current oxygen, the duty cycle will decrease by 3%; and when the absolute value of the difference between the set oxygen and the current oxygen concentration is greater than 0.5, if the set oxygen is less than the current oxygen, the duty cycle will increase by 5%, and if the set oxygen is greater than the current oxygen, the duty cycle will decrease by 5%.

[0125] In addition, when training is started, the system will also obtain the current gas temperature and the set temperature, and adjust the temperature (cooling / heating) according to the current gas temperature and the set temperature. The temperature adjustment method can be semiconductor temperature control, which is achieved by adjusting the duty cycle of the semiconductor refrigeration sheet.

[0126] At standard atmospheric pressure, there are approximate rules to describe the relationship between altitude and temperature:

[0127] The temperature drops by about 0.6℃ for every 100m increase in altitude.

[0128] This rule applies to changes in altitude within a lower range, such as near sea level.

[0129] For a more accurate model, the following linear equation can be used to estimate how temperature varies with altitude:

[0130] T(h)=T0-γ·h;

[0131] Where T(h) is the temperature at an altitude of h meters (℃);

[0132] T0 is the standard temperature at sea level, usually set at 20°C;

[0133] γ is the temperature lapse rate, the unit is ℃ / 100m, and the standard value is about 0.6℃ / 100m;

[0134] h is the altitude in meters.

[0135] The oxygen content simulated in the embodiment of the present application can also be based on Figure 4 The altitude and oxygen content comparison chart shown is adjusted, for example, at an altitude of 3200 meters, the standard oxygen content is 14%.
