[0002] In the micro-pressure oxygen chamber, the gas in the chamber is pressurized to increase the partial pressure of oxygen, forming a micro-pressure oxygen-rich environment in the chamber, thereby increasing the amount of dissolved oxygen in the blood of the user in the micro-pressure oxygen chamber, allowing the human body's tissues and organs to obtain more oxygen supply, and improving the body's metabolic state.

[0003] The detection and regulation of oxygen concentration in a microbaric oxygen chamber is crucial for ensuring the effectiveness of oxygen therapy.

[0063] It should be noted that, in the absence of conflict, the features in the embodiments of this application can be combined with each other.

[0064] Furthermore, in the embodiments of the present application, the term "connection" may refer to "electrical connection" or "direct connection." "Electrical connection" may refer to a direct electrical connection between two components or an electrical connection between two components via one or more normally open tubes or other components.

[0065] To address the technical problems described in the background art, embodiments of the present application provide a method for determining the oxygen concentration in a microcompressive oxygen chamber, a microcompressive oxygen chamber, a processing device for determining the oxygen concentration in a microcompressive oxygen chamber, a computer-readable storage medium, and a computer program product. The method for determining the oxygen concentration in a microcompressive oxygen chamber provided in embodiments of the present application is first described below.

[0066] See Figure 1 , Figure 1 A flowchart of a method for determining the oxygen concentration in a microcompressive oxygen chamber provided in an embodiment of the present application is provided. The method for determining the oxygen concentration in a microcompressive oxygen chamber can be applied to the microcompressive oxygen chamber or the processing equipment for determining the oxygen concentration in the microcompressive oxygen chamber in the following embodiments.

[0067] The processing device for determining the oxygen concentration in the micro-pressure oxygen chamber may be a vehicle, a vehicle-mounted terminal, a mobile terminal, a cloud server, etc.

[0068] When the oxygen concentration processing device in the micro-pressure oxygen chamber is a vehicle, the vehicle can be a private vehicle, such as a sedan, SUV, MPV, or pickup truck. The vehicle can also be a commercial vehicle, such as a van, bus, small truck, or large trailer. The vehicle can be a gasoline vehicle or a new energy vehicle. When the vehicle is a new energy vehicle, it can be a hybrid vehicle or a pure electric vehicle.

[0069] When the processing device for determining the oxygen concentration in the microcompressive oxygen chamber is a vehicle, the processing device for determining the oxygen concentration in the microcompressive oxygen chamber includes the microcompressive oxygen chamber. It is understood that the enclosed cabin of the vehicle can be considered a microcompressive oxygen chamber. Generally, the pressure in the microcompressive oxygen chamber is slightly higher than standard atmospheric pressure, such as 1.3 to 1.5 standard atmospheres, and the temperature in the microcompressive oxygen chamber can be set to 25°C.

[0070] The following describes the method for determining oxygen concentration in a microcompressive oxygen chamber from the perspective of the processing equipment used to determine the oxygen concentration in the chamber. For simplicity and uniformity, the "processing equipment for determining oxygen concentration in a microcompressive oxygen chamber" referred to in the following method embodiments will be referred to simply as the "processing equipment."

[0071] The above method for determining the oxygen concentration in the micro-pressure oxygen chamber specifically includes the following steps 110 to 140:

[0072] Step 110: Obtain the amount of carbon dioxide in the micro-compression oxygen chamber at a first moment.

[0073] Step 120: Determine the carbon dioxide increment in the microcompression oxygen chamber from the initial moment to the first moment based on the carbon dioxide amount. The initial moment is the moment when the microcompression oxygen chamber is in a pressurization state.

[0074] Step 130: Determine a first oxygen consumption in the micro-compression oxygen chamber from the initial moment to the first moment based on the carbon dioxide increment.

[0075] Step 140: Determine the target oxygen concentration in the microcompression oxygen chamber at the first moment based on the carbon dioxide increment, the first oxygen consumption, the oxygen production amount, and the first gas amount. The oxygen production amount is the amount of oxygen input into the microcompression oxygen chamber by the oxygen concentrator in the microcompression oxygen chamber from the initial moment to the first moment, and the first gas amount is the amount of gas when the microcompression oxygen chamber is pressurized.

[0076] The method for determining the oxygen concentration in a microcompressive oxygen chamber provided in an embodiment of the present application obtains the amount of carbon dioxide in the microcompressive oxygen chamber at a first moment, and based on the amount of carbon dioxide, determines the incremental amount of carbon dioxide in the microcompressive oxygen chamber from the initial moment when the microcompressive oxygen chamber is in a pressurized state to the first moment. Then, based on the incremental amount of carbon dioxide, determines the first oxygen consumption in the microcompressive oxygen chamber from the initial moment to the first moment. Finally, based on the incremental amount of carbon dioxide, the first oxygen consumption, the oxygen production amount, and the first gas amount, determines the target oxygen concentration in the microcompressive oxygen chamber at the first moment. This entire process eliminates the need for expensive oxygen sensors, eliminates the cost of the oxygen sensors themselves, and saves the debugging and maintenance costs associated with using the oxygen sensors, significantly reducing the cost of detecting the oxygen concentration in the microcompressive oxygen chamber.

[0077] It should be noted that in each specific embodiment of the present application, when it comes to the need to perform relevant processing based on data related to user identity or characteristics such as user information, user behavior data, user historical data, and user location information, the user's permission or consent will be obtained first, and the collection, use, and processing of such data will comply with relevant laws, regulations, and standards. In addition, when the embodiment of the present application needs to obtain the user's sensitive personal information, such as the biometric information in the following embodiments, the user's separate permission or consent will be obtained through a pop-up window, jump to a confirmation page, or voice notification. After clearly obtaining the user's separate permission or consent, the necessary user-related data for the normal operation of the embodiment of the present application will be obtained.

[0078] The following will be Figure 1 Each step of the method is described in detail.

[0079] In step 110 , the processing device may obtain the amount of carbon dioxide in the microcompression oxygen chamber at a first moment to calculate the target oxygen concentration at the first moment.

[0080] The first moment may be any monitoring time point during oxygen therapy using a microcompression oxygen chamber. For example, the first moment may be the 25th minute from the start of operation of the oxygen concentrator in the microcompression oxygen chamber, the 30th minute from the start of operation of the oxygen concentrator, or any other time.

[0081] The volume of the microcompression chamber can be preconfigured and stored in the processing device. For example, in the case of a vehicle cabin, the processing device can determine the corresponding cabin volume based on the vehicle model (here, the model refers to the specific model of the vehicle, such as a G01 vehicle under the G car brand).

[0082] The above-mentioned amount of carbon dioxide is the molar amount of carbon dioxide in the micro-pressure oxygen chamber at the first moment.

[0083] In some embodiments, a carbon dioxide sensor installed in the micro-compression oxygen chamber can be used to collect the carbon dioxide content in the micro-compression oxygen chamber at a first moment. The carbon dioxide sensor can send the collected carbon dioxide content to a processing device, or the processing device can collect the carbon dioxide content collected by the carbon dioxide sensor in real time.

[0084] After determining the carbon dioxide content in the micro-compression oxygen chamber at the first moment, the processing equipment can determine the molar amount of carbon dioxide in the micro-compression oxygen chamber at the first moment based on Dalton's law of partial pressures and the ideal gas state equation, provided that the cabin volume, cabin temperature and cabin pressure of the micro-compression oxygen chamber at the first moment are determined.

[0085] At standard atmospheric pressure, the components and volume ratios in the gas can be found in Table 1 below.

[0086] Table 1

[0087] Atmospheric components Nitrogen oxygen Argon carbon dioxide Other gases Proportion 78％ 21％ 0.934％ 0.0314％ 0.002％

[0088] Other gases in Table 1 include water vapor, inert gases, etc.

[0089] The above ideal gas state equation (also known as the Clapeyron equation) is expressed as follows:

[0090] PV=nRT (1);

[0091] Wherein, P represents the air pressure, which can be collected by the pressure sensor in the micro-pressure oxygen chamber;

[0092] n represents the number of moles, the unit is mol, and the volume of 1 mol of standard gas is: 22.4L / mol;

[0093] R represents the gas constant, which is 8.314 J / (mol·k). The unit of J is m 3 ·Pa;

[0094] T is the thermodynamic temperature, the unit is Kelvin K, T = t + 273.15, t is Celsius temperature;

[0095] V represents the volume of the micro-pressure oxygen chamber, in m 3 .

[0096] Based on the ideal gas state equation and the proportion of carbon dioxide in Table 1, the processing device can determine the amount of carbon dioxide based on the carbon dioxide concentration in the micro-pressure oxygen chamber collected by the carbon dioxide sensor at the first moment.

[0097] It should be noted that, in the case of a cabin of a micro-compression oxygen cabin vehicle, the cabin temperature in the above embodiment can be collected by a temperature sensor installed in the vehicle, and the cabin pressure can also be collected by a pressure sensor installed in the vehicle. There is no need to install a new temperature sensor and pressure sensor in the process of determining the target oxygen concentration in the micro-compression oxygen cabin at the first moment, which can achieve sensor reuse and thereby reduce the cost of detecting the target oxygen concentration.

[0098] In some embodiments, the processing device can obtain the amount of carbon dioxide in the micro-compression oxygen chamber in real time, and thus can determine the oxygen concentration in real time.

[0099] In some embodiments, the processing device can be started when the oxygen concentration in the micro-compression oxygen chamber needs to be detected, and can be in standby or dormant mode when the oxygen concentration in the micro-compression oxygen chamber does not need to be detected. This can reduce the power consumption of the processing device, especially when the processing device is a vehicle, which can improve the vehicle's endurance.

[0100] In some embodiments, the processing device may be configured with an adaptive wake-up mechanism to enable activation when the oxygen concentration in the microbaric oxygen chamber needs to be detected.

[0101] Exemplarily, the adaptive wake-up mechanism includes starting when a detection period is reached, and the first moment is the moment corresponding to the detection period. For example, the processing device starts once every 15 minutes to detect the oxygen concentration in the micro-pressure oxygen chamber.

[0102] In some embodiments, the above detection period can be set according to actual needs.

[0103] In some embodiments, the processing device can dynamically adjust the detection period based on data from the temperature and humidity sensors within the microbaric oxygen chamber. For example, if the processing device determines that the relative humidity within the microbaric oxygen chamber is greater than 80%, the detection period can be shortened, for example, from an initial 15 minutes to 5 minutes. Conversely, if the relative humidity is greater than 80%, the detection period can be increased, for example, from 5 minutes to 15 minutes.

[0104] In step 120, the processing device may further determine a carbon dioxide increment or a carbon dioxide change based on the amount of carbon dioxide in the microcompression oxygen chamber at the first moment determined in the aforementioned embodiment.

[0105] The initial time is the time when the microcompression oxygen chamber is in the pressurization state. In the pressurization state, the door of the microcompression oxygen chamber is closed, the air pressure inside the chamber is the same as that outside the chamber, and the temperature inside the chamber is 25°C.

[0106] Specifically, the processing device calculates the carbon dioxide amount n in the micro-pressure oxygen chamber at the first moment t1. t1 (co2), the carbon dioxide increment △n(co2) in the micro-pressure oxygen chamber from the initial time t0 to the first time t1 is determined as follows:

[0107] Δn(co2)=n t1 (co2)-n t0 (co2) (2);

[0108] In step 130 , the processing device may determine a first oxygen consumption in the micro-compression oxygen chamber from the initial moment to the first moment according to the carbon dioxide increment.

[0109] The first oxygen consumption may refer to the molar amount of oxygen consumed by the passenger in the micro-compression oxygen chamber during a period from the initial moment to the first moment.

[0110] Based on the principle of conservation of mass, under normal circumstances, the consumption of oxygen in the microcompression oxygen chamber is the same as the increase in carbon dioxide. That is, in some embodiments, the increase in carbon dioxide in the microcompression oxygen chamber from the initial moment to the first moment is the first oxygen consumption in the microcompression oxygen chamber from the initial moment to the first moment.

[0111] In step 140, the processing device may determine the target oxygen concentration in the microcompression oxygen chamber at the first moment by combining the oxygen production amount and the first gas amount, based on the aforementioned embodiment, when determining the carbon dioxide increment and the first oxygen consumption in the microcompression oxygen chamber from the initial moment to the first moment.

[0112] The above oxygen production volume is the amount of oxygen input into the micro-compression oxygen chamber by the oxygen concentrator in the micro-compression oxygen chamber from the initial moment to the first moment.

[0113] The first gas volume is the gas volume when the micro-pressure oxygen chamber is pressurized.

[0114] At the first moment after the initial moment and before the moment corresponding to the pressurization state, the oxygen concentration in the micro-pressure oxygen chamber is consistent with the oxygen concentration in the standard atmospheric pressure, and the processing equipment can determine it based on the ideal gas state equation.

[0115] When the first moment is between the moment corresponding to the pressurization state and before the moment corresponding to the oxygen production state, the oxygen production amount is 0, and the first gas amount is the gas amount in the micro-compression oxygen chamber from the pressurization moment to the first moment.

[0116] If the first moment is between the moments corresponding to the oxygen production state, the first gas volume is the gas volume when the pressurization is completed. Generally, the micro-compression oxygen chamber enters the oxygen production state after the pressurization state is completed.

[0117] In one possible implementation, determining a first oxygen consumption in the microcompression oxygen chamber from an initial moment to a first moment based on the carbon dioxide increment includes:

[0118] Determine the target respiratory entropy corresponding to the passengers in the microbaric oxygen chamber;

[0119] The first oxygen consumption in the microbaric oxygen chamber from the initial moment to the first moment is determined according to the carbon dioxide increment and the target respiratory entropy.

[0120] The embodiment of the present application determines the first oxygen consumption in the microcompression oxygen chamber from the initial moment to the first moment through respiratory entropy and in combination with the carbon dioxide increment, which can improve the accuracy of determining the first oxygen consumption, and further improve the accuracy and reliability of the target oxygen concentration in the microcompression oxygen chamber at the first moment.

[0121] The target respiratory quotient (RQ) refers to the ratio of the total amount of carbon dioxide produced by the passengers in the micro-pressure oxygen chamber to the total amount of oxygen consumed.

[0122] In some embodiments, determining a first oxygen consumption in the microbaric oxygen chamber from the initial moment to the first moment based on the carbon dioxide increment and the target respiratory entropy includes:

[0123] The ratio of the carbon dioxide increment to the target respiratory entropy is determined as the first oxygen consumption in the microbaric oxygen chamber from the initial moment to the first moment.

[0124] In some embodiments, the target respiratory entropy may also be a fixed value pre-configured and stored in the processing device.

[0125] In one possible implementation, determining a target respiratory entropy corresponding to a passenger in a microcompression oxygen chamber includes:

[0126] Obtaining biological sign information of passengers in the microbaric oxygen chamber;

[0127] According to the biological sign information, the target respiratory entropy corresponding to the passengers in the micro-pressure oxygen chamber is determined.

[0128] The embodiment of the present application determines the target respiratory entropy corresponding to the passenger through the biological sign information of the passenger in the micro-compression oxygen chamber. The target respiratory entropy can be dynamically determined in combination with the biological sign information detected in real time, which can further improve the accuracy and reliability of the determined target respiratory entropy, and thus improve the accuracy and reliability of determining the target oxygen concentration in the micro-compression oxygen chamber at the first moment.

[0129] The above-mentioned biological sign information may refer to physiological parameters that directly affect human oxygen metabolism.

[0130] In some embodiments, the biological sign information includes at least one of heart rate information and hunger level.

[0131] It should be noted that heart rate information can be obtained through wearable devices connected to passengers. For example, with the passenger's consent, the processing device can wirelessly connect to a wearable device with heart rate monitoring capabilities, such as a smart bracelet or smartwatch, and obtain the heart rate information collected by the wearable device. Alternatively, heart rate information can be collected using sensors already installed in the micro-pressure oxygen chamber, or other forms of passenger monitoring equipment already installed in the micro-pressure oxygen chamber. This also allows for the reuse of existing equipment, thereby reducing the cost of oxygen concentration detection.

[0132] The above hunger level is obtained with the user's consent. For example, when a passenger enters the micro-compression oxygen chamber, the processing device can obtain the passenger's hunger level through voice inquiries, pop-up windows on display devices (display devices include display devices in the micro-compression oxygen chamber or user's wearable devices), etc.

[0133] In some embodiments, the hunger levels include a first level, a second level, and a third level.

[0134] Specifically, the first degree may represent that the passenger is in an extremely hungry state; the second degree may represent that the passenger is in a generally hungry state; and the third degree may represent that the passenger is not in a hungry state.

[0135] In some embodiments, the processing device is pre-configured and stored with a first mapping relationship between different hunger levels and target respiratory entropy.

[0136] For example, the target respiratory entropy corresponding to the first degree is 0.7; the target respiratory entropy corresponding to the second degree is 0.8; and the target respiratory entropy corresponding to the third degree is 0.85.

[0137] In some embodiments, different heart rate information may be used to indicate that a passenger is in different states.

[0138] For example, a heart rate of 60 to 80 beats per minute may indicate that the passenger is in a resting state; a heart rate of 80 to 100 beats per minute may indicate that the passenger is in a normal exercise state; and a heart rate exceeding 100 beats per minute may indicate that the passenger is in a deep exercise state.

[0139] In some embodiments, a second mapping relationship between the passenger state and the target respiratory entropy is pre-configured and stored in the processing device.

[0140] For example, the target respiratory entropy corresponding to the resting state is 0.85; the target respiratory entropy corresponding to the normal exercise state is 1; and the target respiratory entropy corresponding to the deep exercise state is 1.1.

[0181] See Figure 2 , Figure 2 A flow chart of determining a target oxygen concentration included in a method for determining the oxygen concentration in a micro-pressure oxygen chamber provided in an embodiment of the present application.

[0182] In one possible embodiment, step 140 determines the target oxygen concentration in the microcompression oxygen chamber at the first moment based on the carbon dioxide increment, the first oxygen consumption, the oxygen production amount, and the first gas amount, including but not limited to steps 210 to 230:

It should be noted that to calculate the oxygen concentration in the microcompression chamber at any time during or before the oxygen concentrator is operating, simply use the value corresponding to the corresponding operating time during the calculation process. If the operating time is 0, the amount of oxygen generated or the amount of gas input during the corresponding period is also 0.

[0244] Accordingly, the target oxygen concentration in the microbaric oxygen chamber at the first moment can be expressed as follows:

[0245] G(o2)=[n1(o2)+n mac (o2)–n use1 (o2)] / [n2–n use1 (o2)-n t1 (co2)].
