Description

Technical Field

[0001] This application relates to the field of medical equipment technology, and in particular to a high and low oxygen control device and system. Background Technology

[0002] High and low oxygen devices are a type of equipment capable of simulating or regulating oxygen concentration environments. They are widely used in medical, scientific research, and sports training fields. They can precisely control oxygen concentration to meet different experimental or therapeutic needs, and maintain stable oxygen concentration during long-term operation to ensure experimental or therapeutic effects. They also possess comprehensive safety protection measures, such as overpressure protection and leak detection, to ensure safety during use. Existing high and low oxygen devices, such as the "Physiotherapy Equipment for Rapid Alternating Hot and Cold Compress Therapy" (application number CN207118958U), receive external PWM signals with different duty cycles through a proportional valve control circuit. The PWM signals are optocoupled and isolated by an isolation circuit, making the proportional valve control circuit unaffected by external voltage fluctuations. The optocoupled PWM signal is input to the base of the first and second transistors, controlling their conduction and driving the MOSFET to switch on and off, thus allowing the proportional valve to precisely maintain a certain opening. An LED illuminates to indicate the operating status of the proportional valve.

[0003] However, this solution is an open-loop control method, which cannot monitor oxygen concentration in real time and cannot make precise adjustments. Furthermore, when the user adjusts the oxygen concentration, the oxygen concentration cannot be monitored in real time, resulting in a significant lag and failing to produce a noticeable effect on the user.

[0050] Current high and low oxygen devices use an open-loop control method, which cannot monitor oxygen concentration in real time and cannot make precise adjustments. Furthermore, when users adjust the oxygen concentration, the oxygen concentration cannot be monitored in real time, resulting in a significant lag and failing to produce a noticeable effect on users.

[0051] Based on this, the high and low oxygen control device and system provided by this utility model embodiment detects the oxygen concentration in the gas generated by the gas generating module in real time based on the gas concentration detection module, and outputs the oxygen concentration signal to the main control module. The main control module adjusts the oxygen concentration in the gas generated by the gas generating module based on the oxygen concentration signal, avoiding the problem that existing high and low oxygen devices do not have real-time adjustment capabilities, and achieving precise adjustment to ensure the effect for users.

[0052] To understand this embodiment, a high and low oxygen control device disclosed in this utility model embodiment will first be described in detail.

[0053] Example 1

[0054] Please refer to Figure 1 The high and low oxygen control device 1 provided in this application embodiment includes a gas generation module 11, a main control module 12, a gas concentration detection module 13, a gas delivery pipeline 14, a breathing mask 15, and a human-machine interaction module 16.

[0055] The gas generating module 11 is connected to the main control module 12, the gas concentration detection module 13, and the gas delivery pipeline 14. The gas concentration detection module 13 is connected to the gas generating module 11 through the gas pipe 17. The gas concentration detection module is also connected to the main control module. The gas generating module is connected to the breathing mask 15 through the gas delivery pipeline 14. The main control module is also connected to the human-machine interaction module 16.

[0056] The high and low oxygen control device 1 includes a main control module 12, such as... Figure 2 As shown, this is the main control module 12 and its supporting circuits. These supporting circuits are all fixed-configuration circuits for the main control module 12 and are familiar to those skilled in the art. The main control module uses a GD32F103VCT6 processor U1. This processor is a domestically produced processor. Using a domestic processor can reduce costs, shorten the procurement cycle, and facilitate later production while meeting system performance requirements. The main control module also includes a download port J1 for downloading the signals generated and received by the main control module 12, as well as the related signal conversion data, for data or signal migration. The human-machine interaction module 16, as shown... Figure 3As shown, the system includes a display screen P8 and a communication module P7. The communication module P7 includes a 4G module. The size of the display screen P8 is determined according to the industrial design plan of the product. Since the human-machine interaction module 16 needs to interact with the user, a capacitive touchscreen is used. Because the high and low oxygen control device 1 needs to store a large amount of data, a 12.1-inch Android screen can be used. The Android screen is powered by DC 12V. The human-machine interaction module is also equipped with a MAX3232ESE output chip U5 to ensure the effectiveness of outputting the concentration signal to the main control module 12. The gas generation module 11 is used in the main control module 1... Under the control of module 2, the gas generates the oxygen concentration required by the user. The gas concentration detection module 13 is connected to the gas generation module 11 through the air tube 17, that is, the gas flows to the gas concentration detection module 13 through the air tube 17. The oxygen concentration sensor in the gas concentration detection module 13 adopts a customized R-4OX-D oxygen concentration sensor module. The gas concentration detection module 13 is connected to the main control module 12 through a serial port, which can realize the real-time acquisition of oxygen concentration parameters in the air tube 17. The breathing mask 15 obtains the gas generated by the gas generation module 11 through the gas delivery pipe 14 for the user's use.

[0057] In conjunction with the above embodiments, the gas concentration detection module 13 is used to detect the gas generated by the gas generation module 11 through the gas tube 17 and output an oxygen concentration signal to the main control module 12.

[0058] The main control module 12 is used to control the gas generation module 11 to output gas to the breathing mask 15 through the gas delivery pipe 14 based on the oxygen concentration signal.

[0059] The human-computer interaction module 16 is used to set the concentration signal of oxygen in the gas generated by the gas generation module 11 and output the concentration signal to the main control module 12.

[0060] The gas generation module 11 is used to generate oxygen gas of different concentrations under the control of the main control module 12 based on the concentration signal, and output the gas to the gas concentration detection module 13.

[0061] The gas concentration detection module 13 is used to detect the gas generated by the gas generating module 11 transmitted through the air tube 17 via a built-in oxygen concentration sensor. The oxygen concentration sensor obtains an oxygen concentration signal based on the detected oxygen concentration and outputs the oxygen concentration signal to the main control module 12. The main control module 12 then compares the oxygen concentration signal with the oxygen concentration signal set by the human-machine interaction module 16. If the oxygen concentration corresponding to the oxygen concentration signal is within the range of the concentration signal, the main control module 12 controls the gas generated by the gas generating module 11 to be output to the breathing mask 15 through the gas delivery pipe 14 for user use. The human-machine interaction module 16 allows the user to set the oxygen concentration in the gas generated by the gas generating module 11 via a display screen, converts it into a concentration signal, and outputs the concentration signal to the main control module 12. The main control module 12 then compares the concentration signal with the oxygen concentration signal to adjust the oxygen concentration in the gas generated by the gas generating module 11.

[0062] In conjunction with the above embodiments, such as Figure 4 As shown, the gas concentration detection module 13 further includes a status detection module 131, which is connected to the main control module 12;

[0063] The status detection module 131 is used to collect the user's body data signals and send the body data signals to the main control module;

[0064] The main control module 12 is also used to regulate the gas generated by the gas generating module 11 based on the body data signal.

[0065] The status detection module 131 is used to collect the user's body data signals, including blood oxygen data signals and heart rate data signals, and send the body data signals to the main control module. The transmission method can be a wired connection, such as serial communication. The main control module sets corresponding safety ranges for the user's blood oxygen data signals and heart rate data signals, respectively. If the range is met, the main control module does not adjust the oxygen concentration in the gas generated by the gas generating module 11. If the range is not met, the main control module 12 controls the gas generating module 11 to adjust the oxygen concentration in the gas generated accordingly, so that the user's body adapts to the oxygen environment provided by the high and low oxygen control device.

[0066] In conjunction with the above embodiments, the status detection module 131 includes a blood oxygen saturation module worn on the user's finger.

[0067] The status detection module 131 is a customized blood oxygen saturation module. During use, it needs to be worn on the user's finger to detect the user's blood oxygen and heart rate data signals. The specific detection principle is based on existing mature technology, which will not be elaborated here. The collected blood oxygen and heart rate data signals are output as body data signals to the main control module 12. The main control module then converts the blood oxygen and heart rate data signals into corresponding blood oxygen and heart rate data to ensure the user's safety.

[0068] In conjunction with the above embodiments, the gas generating module 11 includes an air compressor 111, a diaphragm 112, a proportional valve 113, and a pipeline 114. The air compressor 111, the diaphragm 112, and the proportional valve 113 are connected in sequence, and the diaphragm 112 and the proportional valve 113 are connected through the pipeline 114.

[0069] The air compressor 111 is used to generate gas;

[0070] The diaphragm 112 is used to separate oxygen and nitrogen from the gas produced by the air compressor 111, and output oxygen and nitrogen to the proportional valve through the pipeline 114 respectively.

[0071] The proportional valve 113 is used to mix the oxygen and nitrogen separated by the diaphragm 112 to obtain gases with different concentrations of oxygen.

[0072] The air compressor, also known as a compressor, is used to generate high-pressure, high-temperature gas. After cooling, drying, filtering, and sterilization, the gas is output and fed into the diaphragm 112. The diaphragm 112 separates nitrogen and oxygen from the gas. The pipeline 114 includes a nitrogen pipeline and an oxygen pipeline. The nitrogen pipeline is used to output the separated nitrogen to the proportional valve 113, and the oxygen pipeline is used to output the separated oxygen to the proportional valve 113. When the user sets the gas generation module 11 to generate low oxygen through the human-machine interaction module 16, the high / low oxygen control device 1 is in low oxygen mode, and the main control module 12 controls the nitrogen. Nitrogen is output from the pipeline, generating low-oxygen gas with a concentration of 9%. The main control module 12 generates low-oxygen gas with a concentration of 9% to 16% by controlling the ratio of low-oxygen gas to nitrogen, thereby achieving the effect of oxygen concentration regulation. When the user sets the gas generation module 11 to generate high oxygen through the human-machine interaction module 16, that is, when the high-low oxygen control device 1 is in high-oxygen mode, the main control module 12 controls the oxygen output from the oxygen pipeline, generating high-oxygen gas with a concentration of 36%. The main control module 12 generates high-oxygen gas with a concentration of 25% to 36% by controlling the ratio of high-oxygen gas to nitrogen, thereby achieving the effect of oxygen concentration regulation.

[0073] In conjunction with the above embodiments, the gas generating module 11 further includes a gas control unit 115, which is connected to the main control module 12 and the pipeline 114 respectively;

[0074] The gas control unit 115 is used to control the output of oxygen or nitrogen from the pipeline 114.

[0075] The pipes in the gas generating module 11 are respectively nitrogen pipes and oxygen pipes. Therefore, the gas control unit 115 included in the gas generating module 11 is also divided into a first control unit and a second control unit. The first control unit is connected to the nitrogen pipe, and the second control unit is connected to the oxygen pipe. In low oxygen mode, the first control unit is turned on and the second control unit is turned off, so nitrogen is output from the nitrogen pipe. In high oxygen mode, the first control unit is turned off and the second control unit is turned on, so oxygen is output from the oxygen pipe, thereby enabling the gas generating module 11 to generate gases with different concentrations of oxygen.

[0076] In conjunction with the above embodiments, the gas control unit 115 includes a solenoid valve.

[0077] The gas control unit 115 includes a solenoid valve, and the first control unit and the second control unit are also solenoid valves, thereby enabling the corresponding pipelines to be opened or closed under the control of the main control module 12. For example, in low oxygen mode, the solenoid valve corresponding to the first control unit is turned on and the solenoid valve corresponding to the second control unit is turned off, so nitrogen is output from the nitrogen pipeline. In high oxygen mode, the solenoid valve corresponding to the first control unit is turned off and the solenoid valve corresponding to the second control unit is turned on, so that the gas generating module 11 generates oxygen gas of different concentrations.

[0078] In conjunction with the above embodiments, the gas generating module 11 further includes a heat sink 116, which is connected to the main control module 12;

[0079] The heat sink 116 is used to dissipate heat from the gas generating module 11 under the control of the main control module 12.

[0080] The gas generating module 11 also includes a heat sink 116, which can be a cooling fan or other devices capable of heat dissipation, such as... Figure 5As shown, diode D21 is a freewheeling diode used to protect heat sink 116. Cooling fan P20 is a type of heat sink 116 used for heat dissipation. LED9 indicates whether cooling fan P20 is running. V24 is a positive power supply voltage used to dissipate the high temperature generated by air compressor 111 in the gas generation module 11 after long-term operation. Specifically, when the main control module 12 detects high temperature in air compressor 111, it activates the heat dissipation control unit connected to heat sink 116. The heat dissipation activation unit activates heat sink 116 to dissipate heat for gas generation module 11. The heat dissipation control unit includes a relay. When the main control module 12 detects high temperature in air compressor 111, it outputs a heat dissipation signal to the relay. The relay activates based on the heat dissipation signal, controlling heat sink 116 to activate and dissipate heat for gas generation module 11.

[0081] In conjunction with the above embodiments, the main control module 12 further includes a reset unit 121, which is connected to the main control module 12;

[0082] The reset unit 121 is used to output a reset signal to the main control module 12;

[0083] The main control module 12 is also used to control the gas generating module 11 to reset based on the received reset signal.

[0084] After the user uses the high / low oxygen control device 1, the gas generating module 11 stops generating gas of different oxygen concentrations to the breathing mask. At this time, the main control module 12 outputs a reset signal to the gas generating module 11. The gas generating module resets based on the reset signal output by the reset unit 121. The reset unit 121, as shown in the example... Figure 6 As shown, the Zener diode D1 is the protection device of the main control module 12, the resistors R4-R5 supply power to the reset unit 121, and the capacitor C9 is used for filtering, thereby clearing the oxygen concentration set by the user through the human-machine interaction module 16, so as to receive the oxygen concentration set by the user for the next use.

[0085] Example 2

[0086] Embodiments of this application also provide a high / low oxygen control system, such as... Figure 7 As shown, the system includes any one of the high and low oxygen control devices 1 and server 2, wherein the high and low oxygen control device 1 is communicatively connected to the server 2.

[0087] The server 2 is used to send gas production commands to the high and low oxygen control device 1;

[0088] The high and low oxygen control device 1 is used to receive gas generation commands and generate gas in response to the gas generation commands.

[0089] The server 2 can be a computer or other intelligent device, or it can be the host of the high / low oxygen control device 1. The specific configuration can be adjusted according to actual conditions. The high / low oxygen control device 1 communicates with the server 2, which can be either wired or wireless, depending on the specific situation. For example, if the server 2 is a standalone computer, a wireless communication connection can be used; if the server 2 is the host of the high / low oxygen control device 1, a wired communication connection can be used. After the high / low oxygen control device 1 starts working, the server 2 sends a gas production command to the high / low oxygen control device 1. This gas production command can be pre-generated or generated instantly. The high / low oxygen control device 1 receives and responds to the gas production command. The main control module 12 then controls the gas generation module 11 to start producing oxygen gas of different concentrations, thereby ensuring the user's desired experience.

[0090] The high and low oxygen control system provided in this embodiment has the same technical features as the high and low oxygen control device provided in the above embodiment, so it can also solve the same technical problems and achieve the same technical effects.
