Description
Oxygen supply mode switching method, device, equipment and storage medium
[0001] The present application claims priority to the Chinese patent application No. 202410437958.0, filed on April 12, 2024, and entitled "Oxygen supply mode switching method, device, equipment and storage medium", the whole content of which is incorporated herein by reference. TECHNICAL FIELD
[0002] The present application relates to the technical field of oxygen generator, in particular to an oxygen supply mode switching method, device, equipment and storage medium. BACKGROUND
[0003] The portable oxygen generator is different from the medical oxygen generator, has the advantages of compact structure, small size, light weight and convenient carrying, and is suitable for use in various environments such as home or travel, and meets the oxygen inhalation needs of different groups of people.
[0004] The oxygen generation technology used by the portable oxygen generator is generally pressure swing adsorption or vacuum pressure swing adsorption, the principle of which is to use zeolite molecular sieve to adsorb nitrogen and other gases in air, and finally separate oxygen-rich air. The oxygen supply mode of the existing portable oxygen generator generally includes continuous oxygen supply mode and pulse oxygen supply mode. The oxygen provided by the continuous oxygen supply mode is continuous and the flow rate is constant. The oxygen provided by the pulse oxygen supply mode is supplied in stages according to the system settings. When the above two modes run at the same oxygen supply flow rate, the continuous oxygen supply mode can only make the user obtain about 30% of the oxygen supply amount, and the pulse oxygen supply mode can make the user obtain about 100% of the oxygen supply amount. The above two oxygen supply modes can be switched by manual operation; in the pulse oxygen supply mode, there are usually multiple pulse gear settings to provide different oxygen supply flow rates to meet the oxygen inhalation needs of people in different activity states, and the switching between multiple pulse gears is also completed by manual operation.
[0005] Currently, the portable oxygen generator often has the following problems in actual use: In one case, when the user is sleeping or the oxygen inhalation tube is not worn properly, if the device is in pulse oxygen supply mode at this time, the negative pressure value of the user's inhalation cannot reach the trigger threshold, and the device will stop oxygen supply. When the user's inhalation negative pressure again triggers the threshold, the device will resume oxygen supply, which will affect the user's oxygen inhalation effect. In another case, when the user is in an active state, the oxygen supply amount required by the user will increase with the increase of the breathing frequency. If the device is in continuous oxygen supply mode at this time, the user may not get enough oxygen amount, which cannot meet the user's oxygen inhalation needs and cannot improve the situation where the user has low blood oxygen saturation.
[0006] In summary, the existing portable oxygen generator cannot automatically adjust the oxygen supply mode according to the needs of the user, and there are many inconvenient problems in use. SUMMARY

[0054] The above-described embodiments have been shown and described, and the following detailed description will be given. These drawings and detailed description are not intended to limit the scope of the present application in any way, but to explain the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION
[0055] The exemplary embodiments will be described in detail herein below with reference to the accompanying drawings. In the following description, the same drawings refer to the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application.
[0056] The existing portable oxygen generator is based on the pressure swing adsorption method. Fig. 1 is a schematic diagram of a portable oxygen generator according to an embodiment of the present application. As shown in Fig. 1, air passes through a first filter and a second filter into an air compressor, which can compress the air. The compressed air enters a gas control valve, which is connected to two molecular sieve adsorption separation devices. When the compressed air flows into one of the molecular sieve adsorption separation devices to produce oxygen, the other molecular sieve adsorption separation device releases separated nitrogen. The gas control valve can control the flow of gas into or out of the two molecular sieve adsorption separation devices. The nitrogen discharged through the gas control valve is discharged into the atmosphere through an exhaust silencer. The oxygen produced by the molecular sieve adsorption separation device is stored in an oxygen storage tank through a one-way valve. The oxygen storage tank is connected to a pulse valve and a continuous valve. The oxygen passes through an oxygen concentration sensor and an oxygen outlet into an oxygen inhalation tube and is transmitted to the user. At the same time, a control panel can be provided on the portable oxygen generator. The control device can be connected to the control panel to control the opening or closing of the corresponding valve according to the selected oxygen supply mode in the control panel.
[0057] In addition, a pressure sensor and an oxygen saturation detection module are provided in the portable oxygen generator. One end of the pressure sensor is connected to the outlet of the oxygen concentration sensor, and the other end is connected to the control device, so that the control device can obtain the pressure value in the oxygen inhalation tube. One end of the oxygen saturation detection module is directly connected to the user, and the other end is connected to the control device, so that the control device can obtain the oxygen saturation of the user.
[0058] Fig. 2 is a schematic diagram of a gas control according to an embodiment of the present application. In order to realize different oxygen supply modes, two valves are used in parallel to supply oxygen in the oxygen supply path. The oxygen storage tank supplies oxygen to the user through the continuous valve and the pulse valve. In the pulse oxygen supply mode, the pulse valve can be opened intermittently according to the breathing action, or the pulse valve can be closed. In the continuous oxygen supply mode, the continuous valve can be controlled to be opened to realize continuous oxygen supply.
[0059] Two-way valve control is to meet the needs of two oxygen supply modes. In the pulse oxygen supply mode, oxygen needs to be supplied quickly, so the aperture of the valve needs to be increased to increase the peak flow rate of oxygen to achieve rapid oxygen supply. The pulse oxygen supply mode needs to determine the amount of oxygen supplied at a time, limit the consistency of oxygen pulse at a time, and complete the delivery of oxygen within the first 60% of the user's inhalation time. Continuous oxygen supply mode refers to continuous oxygen supply. During the oxygen supply process, the valve is in the open state. Since the two molecular sieve adsorption separation devices are time-sharing and alternately used to produce oxygen, the pressure in the oxygen storage tank is floating, so the gas path aperture needs to be reduced.
[0060] The existing portable oxygen generator, when the user is sleeping or the oxygen inhalation tube is not worn properly, if the device is in pulse oxygen supply mode at this time, the negative pressure value of the user's inhalation cannot reach the trigger threshold, and the device will stop oxygen supply. When the user's inhalation negative pressure triggers the threshold again, the device will resume oxygen supply, which will affect the user's oxygen inhalation effect. Another situation is that when the user is in an active state, the user's required oxygen supply flow will increase with the increase of the breathing frequency. If the device is in continuous oxygen supply mode at this time, it provides fixed oxygen flow, but the flow rate is low, and the user inhales less oxygen, which cannot meet the user's oxygen inhalation demand and cannot improve the situation of low blood oxygen saturation (pulse oxygen supply mode is needed when blood oxygen saturation is low to increase the amount of oxygen inhaled each time and improve blood oxygen saturation). Therefore, the user needs to manually switch the oxygen supply mode to meet the user's oxygen inhalation demand in different scenarios. Manual switching is inconvenient for the user, so the present application provides an intelligent mode for the oxygen generator. When the intelligent mode is turned on, it can automatically switch between pulse oxygen supply mode and continuous oxygen supply mode according to the user's breathing state, realize oxygen supply according to the user's demand, improve oxygen utilization rate, and prolong the service life of the oxygen generator.
[0061] FIG. 3 is a flowchart of an oxygen supply mode switching method provided by an embodiment of the present application. As shown in FIG. 3, the method comprises steps S301 to S303:
[0062] Step S301, when it is detected that the intelligent mode is turned on, the first breathing state of the user is detected.
[0063] In order to realize automatic switching of the oxygen supply mode, an intelligent mode is provided here, which can be set on the control panel. When the control device detects that the intelligent mode is turned on, the first breathing state of the user can be detected to determine the first oxygen supply mode according to the first breathing state.
[0064] Optionally, when the smart mode is detected to be turned on, the pulse valve and the continuous valve can be controlled to be closed first, so that the pressure value in the oxygen inhalation tube is 0 when the user does not breathe, and then the pressure trigger mode is used to determine the first breathing state. That is, the pressure value in the oxygen inhalation tube is obtained, the pressure value is compared with the trigger threshold value, and the first breathing state of the user is determined.
[0065] Step S302, determining a first oxygen supply mode according to the first breathing state, and supplying oxygen according to the first oxygen supply mode.
[0066] When the first breathing state is determined, the first oxygen supply mode can be determined, so that the valve corresponding to the first oxygen supply mode can be controlled to be opened.
[0067] When the first oxygen supply mode is determined to be the pulse oxygen supply mode, the pulse valve can be controlled to be opened and closed at a time, and oxygen can be supplied. When the first oxygen supply mode is the continuous oxygen supply mode, the continuous valve can be controlled to be opened and oxygen can be supplied.
[0068] According to the first oxygen supply mode, the oxygen supply includes:
[0069] When the first oxygen supply mode is the pulse oxygen supply mode, a target operating gear is determined, and the target operating gear is operated.
[0070] Since the pulse oxygen supply mode usually has multiple operating gears, the user usually needs to manually select a suitable operating gear, which causes inconvenience. When the oxygen generator is determined to work in the first oxygen supply mode, the target operating gear can be automatically determined, so that the user does not need to manually select a suitable operating gear, and the user experience is improved.
[0071] Step S303, detecting a second breathing state of the user in the first oxygen supply mode, and determining whether to switch the first oxygen supply mode to a second oxygen supply mode according to the second breathing state; the oxygen supply mode includes a pulse oxygen supply mode and a continuous oxygen supply mode.
[0072] When the portable oxygen generator works in the first oxygen supply mode, the second breathing state of the user can also be obtained in real time, so that it is determined whether to continue to supply oxygen in the first oxygen supply mode or to switch to the second oxygen supply mode according to the second breathing state.
[0073] When the respiratory strength is weak, there is no inhalation action, sleep or the oxygen inhalation tube is not worn properly, if the pulse oxygen supply mode is continued to be used for oxygen supply, there is a problem that oxygen cannot be supplied in time, at this time, continuous oxygen supply mode can be used for oxygen supply. When the user has inhalation action, if the continuous oxygen supply mode is continued to be used for oxygen supply, since the user cannot inhale oxygen during exhalation, there is a problem that the oxygen utilization rate is low and the user inhales insufficient oxygen. In addition, when the user is in an active state, the problem of low blood oxygen saturation is prone to occur, if the continuous oxygen supply mode is continued to be used for oxygen supply, the oxygen flow rate is low, and the problem of low blood oxygen saturation cannot be improved. Therefore, by detecting the second respiratory state, the oxygen supply mode can be switched to be more suitable for the current breathing condition of the user, so as to improve the oxygen utilization rate under the condition that the oxygen supply is guaranteed, thereby improving the service life of the oxygen generator.
[0074] The portable oxygen generator has certain limitations in molecular sieve adsorption capacity and battery endurance in order to realize compact structure, small size and light weight. By setting the intelligent mode, pulse oxygen supply mode can be used for oxygen supply when the user meets the conditions. The pulse oxygen supply mode is an intermittent oxygen supply mode, which can save cost, prolong the service life of the equipment, and also can increase the battery endurance time compared with the continuous oxygen supply mode.
[0075] The method provided by the application can also improve the use effect of the user. When the user has inhalation action, if the continuous oxygen supply mode is continued to be used for oxygen supply, the user cannot quickly inhale more oxygen, so the oxygen inhalation effect of the user is poor. If the pulse oxygen supply mode is used, more oxygen can be quickly inhaled, and the oxygen inhalation effect of the user is improved.
[0076] The oxygen supply mode switching method provided by the application detects the first respiratory state of the user when the intelligent mode is detected to be started, determines the first oxygen supply mode according to the first respiratory state, and supplies oxygen according to the first oxygen supply mode. The second respiratory state of the user is detected under the first oxygen supply mode, and it is determined whether to switch the first oxygen supply mode to the second oxygen supply mode according to the second respiratory state. The oxygen supply mode includes pulse oxygen supply mode and continuous oxygen supply mode. Oxygen is supplied according to the first oxygen supply mode, which includes: when the first oxygen supply mode is pulse oxygen supply mode, the target running gear position is determined, and the target running gear position is run, which can realize self-switching between the two oxygen supply modes according to the user's demand and automatically determine the target running gear position suitable for the user in the pulse oxygen supply mode, meet the oxygen inhalation demand of the user in different scenes, improve the use effect of the user, and at the same time, the method can improve the oxygen utilization rate under the condition that the oxygen supply is guaranteed, improve the service life of the oxygen generator, and reduce the use cost.
[0077] Optionally, the first breathing state is whether there is a breathing action in a first preset time length; the first oxygen supply mode is determined according to the first breathing state, including:
[0078] When the first breathing state is that there is a breathing action in the first preset time length, it is determined that the first oxygen supply mode is the pulse oxygen supply mode; the breathing action means that the pressure value in the oxygen inhalation tube is detected to be less than a first trigger threshold at a first time and greater than a second trigger threshold at a second time; the second time is after the first time;
[0079] When the first breathing state is that there is no breathing action in the first preset time length, it is determined that the first oxygen supply mode is the continuous oxygen supply mode.
[0080] When determining the first oxygen supply mode, the pressure trigger mode can be used to determine the first breathing state first. In order to quickly determine the first oxygen supply mode, the first breathing state can be whether there is a breathing action in a first preset time length. For example, the first preset time length can be 30 seconds. When there is a breathing action in the first preset time length, the pulse oxygen supply mode is used for oxygen supply, wherein the breathing action means that the pressure value in the oxygen inhalation tube is detected to be less than a first trigger threshold at a first time and greater than a second trigger threshold at a second time; the second time is after the first time. When the above conditions are met, it means that one inhalation action and one exhalation action are detected, and the pulse oxygen supply mode can be used for oxygen supply to improve oxygen utilization. For example, when a breathing action is detected at the 10th second, the pulse valve is opened to use the pulse oxygen supply mode for oxygen supply.
[0081] Fig. 4 is a trigger schematic diagram of the pulse oxygen supply mode provided by the embodiment of the application. As shown in Fig. 4, after it is determined that the pulse oxygen supply mode is used for oxygen supply, when an inhalation action is detected, that is, the pressure value in the oxygen inhalation tube is detected to be less than a first trigger threshold, the pulse valve can be opened, and when the transmitted oxygen amount reaches a single oxygen pulse amount, the pulse valve is closed.
[0082] On the contrary, when the first breathing state is that there is no breathing action in the first preset time length, it is determined that the first oxygen supply mode is the continuous oxygen supply mode, and the continuous oxygen supply mode is used at this time to ensure that the user can inhale oxygen in any state. For example, when no breathing action is detected in 30 seconds, the continuous valve is opened in the next second to use the continuous oxygen supply mode for oxygen supply, wherein the pulse valve and the continuous valve are both in a closed state in the previous 30 seconds.
[0083] The pressure trigger mode is used to determine the breathing state. When inhaling, the user needs to reduce the alveolar pressure to generate a pressure gradient between the alveoli and the oral cavity, so that the oral cavity pressure is higher than the alveolar pressure to generate inhalation. When the user does not inhale, the pressure in the oxygen inhalation tube is the same as the atmospheric pressure. When the user inhales, the pressure in the oxygen inhalation tube is lower than the atmospheric pressure. When the pressure in the oxygen inhalation tube is lower than the first trigger threshold, it is determined that there is an inhalation action. When the user exhales, the pressure in the oxygen inhalation tube is greater than the atmospheric pressure. When the pressure in the oxygen inhalation tube is greater than the second trigger threshold, it is determined that there is an exhalation action. The first trigger threshold and the second trigger threshold can determine the trigger sensitivity. The first trigger threshold is a negative value. The greater the first trigger threshold, the smaller the inhalation force required to trigger the pulse oxygen supply mode. Conversely, the smaller the first trigger threshold, the greater the inhalation force required to trigger the pulse oxygen supply mode. Therefore, the first trigger threshold and the second trigger threshold can be set according to actual conditions.
[0084] The first oxygen supply mode is determined by the first breathing state, which can quickly and accurately determine the first oxygen supply mode.
[0085] Optionally, the second breathing state is used to determine whether to switch the first oxygen supply mode to the second oxygen supply mode, which includes:
[0086] When the first oxygen supply mode is the pulse oxygen supply mode, the second breathing state is the same as the first breathing state. If the second breathing state is that there is no breathing action within the first preset time period, the pulse oxygen supply mode is switched to the continuous oxygen supply mode.
[0087] When the first oxygen supply mode is the continuous oxygen supply mode, if the second breathing state is that there are N breathing actions within the second preset time period, the continuous oxygen supply mode is switched to the pulse oxygen supply mode.
[0088] When determining whether to switch the first oxygen supply mode to the second oxygen supply mode, the second breathing state can be used to determine. The second breathing state can be whether there is a breathing action within the first preset time period, and whether there are N breathing actions within the second preset time period. The specific determination can be made according to the first oxygen supply mode.
[0089] When the first oxygen supply mode is the pulse oxygen supply mode, the second breathing state is whether there is a breathing action within the first preset time length; when the first oxygen supply mode is the continuous oxygen supply mode, the second breathing state is whether there are N breathing actions within the second preset time length. Exemplarily, the first preset time length can be 30 seconds, the second preset time length can be 2 minutes, and the value of N can be 3. Since the continuous oxygen supply mode is switched to the pulse oxygen supply mode, it is necessary to determine whether the user has stable breathing action, and therefore, it can be detected whether there are N breathing actions within the second preset time length, so as to switch to the pulse oxygen supply mode in the case of stable breathing.
[0090] Therefore, in the pulse oxygen supply mode, when it is detected that there is no breathing action within the first preset time length, the continuous oxygen supply mode can be switched; when it is detected that there is a breathing action within the first preset time length, the pulse oxygen supply mode is continued. In the continuous oxygen supply mode, when it is detected that there are N breathing actions (the count value of the breathing action is greater than or equal to N) within the second preset time length, the pulse oxygen supply mode is switched; when it is detected that there are no N breathing actions (the count value of the breathing action is less than N) within the second preset time length, the continuous oxygen supply mode is continued.
[0091] Through the above-mentioned judgment condition, the continuous oxygen supply mode can be switched to the pulse oxygen supply mode when there is a stable breathing action, the pulse oxygen supply mode can be switched to the continuous oxygen supply mode when there is no breathing action, and accurate switching of the oxygen supply mode can be realized.
[0092] Optionally, the method further comprises:
[0093] obtaining a first pressure curve of the last running period, and shifting the first pressure curve downward by a first value to obtain a second pressure curve;
[0094] obtaining a third pressure curve of the current running period, determining that there is an inhalation action when the third pressure curve and the second pressure curve have an intersection point, and determining that there is an exhalation action when the pressure difference of the corresponding time in the last running period and the current running period exceeds a second value;
[0095] when the count value of the inhalation action and the count value of the exhalation action within the second preset time length respectively reach N, it is determined that there are N breathing actions within the second preset time length.
[0096] When the second breathing state is determined to exist N times of breathing actions within the second preset time length in the continuous oxygen supply mode, if the pressure trigger mode is still used to determine the breathing state, there is an inaccuracy problem. Because in the continuous oxygen supply mode, the continuous valve is opened, and oxygen is continuously output. However, due to the working principle of the portable oxygen generator, the two molecular sieve adsorption devices will alternately adsorb and release nitrogen. For example, when the molecular sieve adsorption device 1 adsorbs nitrogen, the molecular sieve adsorption device 2 releases nitrogen, so that a continuous oxygen flow can be formed, and the pressure will fluctuate periodically. The pressure trigger mode is suitable for the case that both valves are closed, that is, the pressure in the oxygen inhalation tube is 0.
[0097] Based on the above problems, the image detection breathing mode can be used to determine whether the second breathing state is N times of breathing actions within the second preset time length.
[0098] FIG. 5 is a schematic diagram of an image detection breathing action provided by an embodiment of the present application. Specifically, the pressure data of the last running period can be obtained to form a first pressure curve, and the first pressure curve can be translated downward by a first value to obtain a second pressure curve. The pressure data of the current running period is obtained to form a third pressure curve, and the second pressure curve and the third pressure curve are compared. When there is no inhalation action or exhalation action, the second pressure curve and the third pressure curve are parallel, and there is no intersection point. When there is an inhalation action, the pressure data of the current running period will be smaller, and the third pressure curve and the second pressure curve will form an intersection point, which is the time when the inhalation action is triggered. When there is an exhalation action, the pressure data of the current running period will be larger, and the data difference between the third pressure curve and the second pressure curve at the corresponding time (a time in the running period) will exceed a second value. The time when the second value is exceeded is the time when the exhalation action is triggered.
[0099] Because in the continuous oxygen supply mode, oxygen is continuously output, the pressure in the oxygen inhalation tube is large, and the sensitivity of the breathing detection is lower than that in the pulse oxygen supply mode.
[0100] Based on the above mode, each inhalation action and exhalation action can be detected in the continuous oxygen supply mode. When N times of inhalation actions and N times of exhalation actions are detected within the second preset time length, it can be determined that there are N times of breathing actions within the second preset time length.
[0101] In the continuous oxygen supply mode, by comparing the pressure data of two running periods, whether the user has a breathing action can be accurately detected.
[0102] Optionally, the oxygen is supplied according to the first oxygen supply mode, comprising:
[0103] When the first oxygen supply mode is the pulse oxygen supply mode, the blood oxygen saturation of the user in N breathing actions is determined.
[0104] When the blood oxygen saturation is less than the target blood oxygen saturation, the total oxygen pulse of the user in N breathing actions is determined according to the breathing frequency and the blood oxygen saturation of the user.
[0105] A first multiplication result of the total oxygen pulse and a first coefficient is calculated, a second multiplication result of a square value of the total oxygen pulse and a second coefficient is calculated, an addition result of the first multiplication result and the second multiplication result and a third coefficient is calculated, the addition result is determined as a target running gear, and the target running gear is run.
[0106] And / or, when the blood oxygen saturation is greater than or equal to the target blood oxygen saturation, a default running gear is determined as a target running gear, and the target running gear is run.
[0107] Since the pulse oxygen supply mode has multiple running gears, in the prior art, when the oxygen generating device is switched from the continuous oxygen supply mode to the pulse oxygen supply mode, the running gear needs to be manually selected, and which running gear needs to be selected also needs to be constantly debugged to confirm, which will be inconvenient for the user, and this mode also cannot provide the appropriate oxygen amount for the user in time.
[0108] In view of the above problems, when the oxygen generating device runs in the pulse oxygen supply mode in the intelligent mode, a target running gear can be automatically determined, so that the user does not need to adjust the running gear by himself.
[0109] Optionally, the blood oxygen saturation of the user in N breathing actions can be detected, the blood oxygen saturation refers to the percentage of the capacity of oxygenated hemoglobin combined with oxygen in the blood to the total capacity of hemoglobin that can be combined, that is, the concentration of blood oxygen in the blood, and the blood oxygen saturation is an important physiological parameter of respiratory cycle. When the blood oxygen saturation is low, it means that the total oxygen pulse required by the current user is large, and when the blood oxygen saturation is high, it means that the total oxygen pulse required by the current user is small. As shown in FIG. 1, a blood oxygen detection module can be arranged between the user and the control device, and the blood oxygen saturation of the user can be obtained through the blood oxygen detection module.
[0110] Optionally, when switching from continuous oxygen supply mode to pulse oxygen supply mode, it indicates that N times of breathing actions have been detected within the second preset time period. At each time of detecting the breathing action, the blood oxygen saturation at that time can be obtained. When the blood oxygen saturation corresponding to each time of detecting the breathing action is less than the target blood oxygen saturation, it indicates that the total amount of oxygen pulse required by the current user is large. The total amount of oxygen pulse can be calculated according to the breathing frequency and the blood oxygen saturation under N times of breathing actions, and the target operating gear can be calculated according to the total amount of oxygen pulse. When the blood oxygen saturation corresponding to each time of detecting the breathing action is greater than the target blood oxygen saturation, it indicates that the total amount of oxygen pulse required by the current user is small. At this time, a default operating gear can be determined as the target operating gear.
[0111] For example, five operating gears can be set. The higher the operating gear, the greater the corresponding total amount of oxygen pulse. Therefore, the default operating gear can be a lower gear, such as operating gear 1 or operating gear 2.
[0112] As shown in Table 1, the operating gear can be five, operating gear 1 to operating gear 5, which respectively correspond to a total amount of oxygen pulse. The higher the operating gear, the greater the total amount of oxygen pulse, that is, A < B < C < D < E.
[0113] Table 1
[0114] Optionally, after determining the total amount of oxygen pulse, the target operating gear can be calculated based on the following formula: L = A + B*P + C*P 2
[0115] Wherein, L represents the target operating gear, A, B and C are constants, and P represents the amount of oxygen pulse per unit time. The target operating gear can be accurately calculated by the above formula. If the target operating gear is directly determined by querying Table 1, the calculated total amount of oxygen pulse can not correspond to an operating gear. For example, the total amount of oxygen pulse is between C and D, so it is not possible to determine whether the target operating gear is gear 3 or gear 4.
[0116] Optionally, when the oxygen production device is started and the intelligent mode is turned on, if the pulse oxygen supply mode is directly entered, N times of breathing actions can not have been detected at this time, and the total amount of oxygen pulse cannot be directly determined. At this time, a target operating gear can be determined first. For example, when there are five operating gears, the target operating gear can be operating gear 3. After N times of breathing actions are detected, the total amount of oxygen pulse can be determined again, so that the target operating gear can be determined again and operated at the target operating gear.
[0117] When the target operation gear is determined, the corresponding total oxygen pulse amount can be determined according to Table 1, and the single oxygen pulse amount per breath can be calculated according to the breathing frequency, and the single oxygen pulse amount is provided when the pulse valve is opened each time.
[0118] By acquiring the blood oxygen saturation of the user in N breathing actions, and determining the target operation gear according to the relationship between the blood oxygen saturation and the target blood oxygen saturation, the accuracy of the determined target operation gear is improved.
[0119] Optionally, the total oxygen pulse amount is determined according to the breathing frequency and the blood oxygen saturation of the user in N breathing actions, including:
[0120] For each blood oxygen saturation, the difference between the target blood oxygen saturation and the blood oxygen saturation is calculated, and the integral result of the difference from the first time to the Nth time is calculated; the Nth time represents the time when the Nth breathing action is detected;
[0121] The third multiplication result of the fourth coefficient and the breathing frequency is calculated, the fourth multiplication result of the third multiplication result and the integral result is calculated, and the fourth multiplication result is determined as the total oxygen pulse amount.
[0122] When calculating the total oxygen pulse amount, the breathing frequency and the blood oxygen saturation of the user can be determined, and specifically, the following formula can be used for calculation:
[0123] Wherein, P represents the total oxygen pulse amount per unit time calculated, t N represents the time when the Nth breathing action is detected, S 目标 represents the target blood oxygen saturation, S t represents the blood oxygen saturation at time t, and Q represents a constant, which can be determined according to actual experience.
[0124] According to the above formula for calculating the total oxygen pulse amount, the smaller the blood oxygen saturation, the larger the calculated total oxygen pulse amount, the larger the breathing frequency 60*(N-1)\(t N -t1), the larger the calculated total oxygen pulse amount, and the calculated total oxygen pulse amount is the total oxygen pulse amount required by the user to inhale.
[0125] Through the above method, the total oxygen pulse amount required by the user can be accurately calculated, so that the target operation gear can be accurately determined.
[0126] Optionally, after running in the target operation gear, the method further includes:
[0127] acquiring a current blood oxygen saturation of the user, if the current blood oxygen saturation is between a first blood oxygen saturation and a second blood oxygen saturation, then controlling the target operation gear to be unchanged, if the current blood oxygen saturation is greater than the second blood oxygen saturation, then decreasing the target operation gear, if the current blood oxygen saturation is less than the first blood oxygen saturation, then increasing the target operation gear, the target blood oxygen saturation is greater than the first blood oxygen saturation and less than the second blood oxygen saturation.
[0128] When the target operation gear is determined, there can be a problem that the determined target operation gear is not accurate, or when the user inhales oxygen for a period of time at the target operation gear, the target operation gear can need to be adjusted again, at this time, the current blood oxygen saturation can be used to fine-tune the target operation gear based on the current target operation gear. In normal circumstances, the blood oxygen saturation of the user needs to be maintained between the first blood oxygen saturation and the second blood oxygen saturation, when the detected current blood oxygen saturation is between the first blood oxygen saturation and the second blood oxygen saturation, the target operation gear can be controlled to be unchanged, when the current blood oxygen saturation is greater than the second blood oxygen saturation, the target operation gear can be decreased, and when the current blood oxygen saturation is less than the second blood oxygen saturation, the target operation gear can be increased.
[0129] For example, the first blood oxygen saturation can be 94%, the second blood oxygen saturation can be 96%, and the target blood oxygen saturation can be 95%.
[0130] When the pulse oxygen supply mode in the intelligent mode is run, the target operation gear is adjusted according to the current blood oxygen saturation, the target operation gear is adjusted according to the oxygen inhalation condition of the user, and the service life of the equipment is improved while the oxygen supply amount is ensured.
[0131] Table 2 is the blood oxygen saturation data of the user when using the oxygen generating equipment and not using the oxygen generating equipment. As shown in Table 2, when the user is in a sitting state and does not use the oxygen generating equipment, the blood oxygen saturation is 95% and the breathing frequency is 25; when the user is in a state of exercising for 30 minutes and does not use the oxygen generating equipment, the blood oxygen saturation is 92% and the breathing frequency is 30; when the user is in a state of exercising for 30 minutes and uses the oxygen generating equipment, the oxygen generating equipment runs at operation gear 2 in the pulse mode, the blood oxygen saturation is 93% and the breathing frequency is 30; when the user is in a state of exercising for 30 minutes and uses the oxygen generating equipment, the oxygen generating equipment runs at operation gear 4 in the pulse oxygen supply mode in the intelligent mode, the blood oxygen saturation is 96% and the breathing frequency is 32; it can be known that the determined operation gear is more accurate by the pulse oxygen supply mode in the intelligent mode compared to the ordinary pulse mode, and the blood oxygen saturation of the user can be in a suitable range.
[0132] Table 2
[0133] Therefore, the smart mode, the pulse mode and the continuous mode can be provided on the control panel of the actual portable oxygen generator. In the initial case, the user can select any mode.
[0134] When the user selects the pulse mode, the portable oxygen generator detects the breathing state in real time. When the pressure value in the oxygen inhalation tube is less than the first trigger threshold, the single oxygen pulse amount is automatically calculated according to the breathing frequency of the user and the gear of the device, and the single oxygen pulse amount is supplied in the user's inhalation stage. When the user has no inhalation action or weak inhalation, the portable oxygen generator supplies oxygen in a timing manner.
[0135] When the user selects the continuous mode, the continuous valve of the portable oxygen generator is in the open state, and the oxygen is supplied continuously. In the continuous mode, the portable oxygen generator will no longer detect the breathing action of the user. Whether the user has inhalation action or not, the portable oxygen generator still supplies oxygen continuously to ensure the oxygen supply.
[0136] When the user selects the smart mode, the pulse mode and the continuous mode can be considered to ensure the oxygen supply and improve the oxygen utilization rate. FIG. 6 is a flowchart of another oxygen supply mode switching method provided by the embodiment of the present application. As shown in FIG. 6, when it is detected that the oxygen generator is in the smart mode, it is detected whether there is breathing action within 30 seconds. If yes, it is determined that the pulse oxygen supply mode is entered, and the oxygen is supplied according to the breathing condition of the user, and it is continued to be judged whether there is breathing action within 30 seconds. If no, it is determined that the continuous oxygen supply mode is entered, and the continuous oxygen supply is performed. At the same time, it is detected whether there are three breathing actions within 2 minutes. If yes, the pulse oxygen supply mode is switched. If no, the continuous oxygen supply mode is continued to supply oxygen.
