Abstract

The present invention relates to the technical field of oxygen chambers, specifically a method and system for regulating an oxygen chamber for alleviating altitude sickness. The regulation method includes obtaining a request instruction for using the oxygen chamber, obtaining vital sign information of the user within a continuous time interval, namely the user's heart rate, blood oxygen saturation, and respiratory rate, and then obtaining the cabin air pressure and cabin oxygen concentration based on the vital sign information. If the vital sign information of the user within the continuous time interval is consistent with the cabin air pressure and cabin oxygen concentration output by a pre-trained adjustment model, the cabin working environment value of the oxygen chamber is maintained at the current value; otherwise, the cabin working environment value of the oxygen chamber is adjusted until the vital sign information of the user within the continuous time interval is consistent with the cabin air pressure and cabin oxygen concentration output by the pre-trained adjustment model. This solves the problem that existing medical oxygen chambers cannot effectively meet users' needs for using oxygen chambers to alleviate altitude sickness due to their location settings and service models.

Description

Technical Field

[0001] The present invention relates to the technical field of oxygen chambers, and in particular to an oxygen chamber control method and system for alleviating altitude sickness. Background Art

[0002] Altitude sickness refers to the body's intolerance to the low oxygen and low pressure environment after entering a high-altitude area from a low altitude, resulting in a series of uncomfortable symptoms such as dizziness, chest tightness, shortness of breath, nausea, and vomiting. The main cause of altitude sickness is a decrease in oxygen content in the air, which leads to hypoxia in the human body and the resulting discomfort. Furthermore, a decrease in atmospheric pressure also contributes to altitude sickness. As altitude increases, air pressure decreases, creating an imbalance between internal and external pressure in the body, causing discomfort such as chest tightness and shortness of breath, which can manifest as altitude sickness.

[0003] An oxygen chamber is a common device used to relieve altitude sickness on plateaus. Its basic working principle is to pressurize a closed container through an oxygen regulator so that the ambient pressure is slightly greater than 1 standard atmospheric pressure, thereby increasing the user's arterial oxygen partial pressure in the oxygen chamber, increasing the ratio of oxygenated hemoglobin in the blood, and improving the oxygen exchange capacity between tissues, thereby alleviating the user's hypoxia symptoms.

[0004] In plateau areas, due to the limitations of hospital infrastructure, the location and service model of traditional medical oxygen chambers have greatly restricted user needs. With the development of 5G technology and the sharing economy, civilian oxygen chambers have made up for the shortcomings of medical oxygen chambers with their more reasonable distribution and convenient service model, greatly satisfying the needs of users in plateau areas to use oxygen chambers to relieve altitude sickness.

[0005] Therefore, the present invention provides an oxygen chamber control method and system for alleviating altitude sickness to solve the above-mentioned problems. Summary of the Invention

[0006] In view of the above situation, in order to overcome the defects of the existing technology, the present invention provides an oxygen chamber control method and system for alleviating altitude sickness, which solves the problem that the existing medical oxygen chambers cannot effectively meet the needs of users to use oxygen chambers to relieve altitude sickness due to their location settings and service modes.

[0010] Based on the user's basic vital signs and estimated arrival time, the oxygen cabin environment is adjusted to different levels of standby mode. The corresponding oxygen cabin environment values ​​for different levels of standby mode include cabin temperature and cabin humidity.

[0011] In response to user input, the user's real-time vital signs information is obtained, and based on the pre-trained adjustment model, the working environment in the oxygen chamber is adjusted. The working environment values ​​in the oxygen chamber include the air pressure and oxygen concentration in the chamber;

[0012] The user's vital sign information obtained in the continuous time interval is the user's heart rate, blood oxygen saturation and respiratory rate, and then the cabin air pressure and the cabin oxygen concentration are obtained based on the vital sign information. If the user's vital sign information in the continuous time interval is consistent with the cabin air pressure and the cabin oxygen concentration output by the pre-trained adjustment model, the cabin working environment value of the oxygen cabin is maintained at the current value; otherwise, the cabin working environment value of the oxygen cabin is adjusted until the user's vital sign information in the continuous time interval is consistent with the cabin air pressure and the cabin oxygen concentration output by the pre-trained adjustment model.

[0046] Figure 2 The figure is a schematic structural diagram of an oxygen chamber control system for alleviating altitude sickness according to the present invention. DETAILED DESCRIPTION

[0047] The following will describe various embodiments of the present invention in detail with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0048] Altitude sickness refers to the body's intolerance to the low oxygen and low pressure environment after entering a high-altitude area from a low altitude, resulting in a series of uncomfortable symptoms such as dizziness, chest tightness, shortness of breath, nausea, and vomiting. The main cause of altitude sickness is a decrease in oxygen content in the air, which leads to hypoxia in the human body and the resulting discomfort. Furthermore, a decrease in atmospheric pressure also contributes to altitude sickness. As altitude increases, air pressure decreases, creating an imbalance between internal and external pressure in the body, causing discomfort such as chest tightness and shortness of breath, which can manifest as altitude sickness.

[0049] An oxygen chamber is a common device used to relieve altitude sickness on plateaus. Its basic working principle is to pressurize a closed container through an oxygen regulator so that the ambient pressure is slightly greater than 1 standard atmospheric pressure, thereby increasing the user's arterial oxygen partial pressure in the oxygen chamber, increasing the ratio of oxygenated hemoglobin in the blood, and improving the oxygen exchange capacity between tissues, thereby alleviating the user's hypoxia symptoms.

[0050] In plateau areas, due to the limitations of hospital infrastructure, the location and service model of traditional medical oxygen chambers have greatly restricted user needs. With the development of 5G technology and the sharing economy, civilian oxygen chambers have made up for the shortcomings of medical oxygen chambers with their more reasonable distribution and convenient service model, greatly satisfying the needs of users in plateau areas to use oxygen chambers to relieve altitude sickness.

[0051] In response to the above problems, the present application provides a method for controlling an oxygen chamber for alleviating altitude sickness, characterized in that the control method comprises the following steps:

[0052] Obtain a request for using the oxygen chamber, which includes the user's basic vital signs information and estimated arrival time;

[0053] Based on the user's basic vital signs and estimated arrival time, the oxygen cabin environment is adjusted to different levels of standby mode. The corresponding oxygen cabin environment values ​​for different levels of standby mode include cabin temperature and cabin humidity.

[0054] In response to user input, the user's real-time vital signs information is obtained, and based on the pre-trained adjustment model, the working environment in the oxygen chamber is adjusted. The working environment values ​​in the oxygen chamber include the air pressure and oxygen concentration in the chamber;

[0055] The user's vital sign information obtained in the continuous time interval is the user's heart rate, blood oxygen saturation and respiratory rate, and then the cabin air pressure and the cabin oxygen concentration are obtained based on the vital sign information. If the user's vital sign information in the continuous time interval is consistent with the cabin air pressure and the cabin oxygen concentration output by the pre-trained adjustment model, the cabin working environment value of the oxygen cabin is maintained at the current value; otherwise, the cabin working environment value of the oxygen cabin is adjusted until the user's vital sign information in the continuous time interval is consistent with the cabin air pressure and the cabin oxygen concentration output by the pre-trained adjustment model.

[0056] The technical solution will be described in detail below in conjunction with specific embodiments.

[0057] Example

[0058] refer to Figure 1 A method for controlling an oxygen chamber for relieving altitude sickness includes the following steps S100-S400:

[0059] S100: Obtain a request instruction for using an oxygen chamber, where the request instruction includes basic vital signs information of the user and an estimated arrival time;

[0060] S200, based on the user's basic vital signs information and estimated arrival time, adjusting the oxygen cabin environment to different levels of standby mode, where the oxygen cabin environment values ​​corresponding to the different levels of standby mode include cabin temperature and cabin humidity;

[0061] S300, in response to user input, obtaining real-time vital sign information of the user, and adjusting the working environment in the oxygen chamber based on a pre-trained adjustment model, where the working environment values ​​in the oxygen chamber include the air pressure and oxygen concentration in the chamber;

[0062] S400. Obtain the user's vital sign information in the continuous time interval, which is the user's heart rate, blood oxygen saturation and respiratory rate, and then obtain the cabin air pressure and cabin oxygen concentration based on the vital sign information. If the user's vital sign information in the continuous time interval is consistent with the cabin air pressure and cabin oxygen concentration output by the pre-trained adjustment model, then maintain the cabin working environment value of the oxygen cabin at the current value; otherwise, adjust the cabin working environment value of the oxygen cabin until the user's vital sign information in the continuous time interval is consistent with the cabin air pressure and cabin oxygen concentration output by the pre-trained adjustment model.

[0063] During specific use, the user searches for available oxygen chambers nearby on the map through a terminal device (mobile phone, computer, tablet, etc.), selects the nearest device as needed, and then fills in the user's basic vital signs information and estimated arrival time. The oxygen chamber terminal adjusts the basic environment of the oxygen chamber to the corresponding level according to the information filled in by the user and goes on standby. At the same time, it issues a prompt message that the oxygen chamber has been booked. Usually, the prompt message is characterized by flashing lights and voice broadcasts. For example, the loop broadcasts "Oxygen chamber No. 0012 has been booked, and the user will arrive in 30 minutes." After the user arrives at the location of the oxygen chamber, the user signs in by scanning the QR code of the oxygen chamber terminal and opens the oxygen chamber door. After entering the oxygen chamber, the user wears auxiliary equipment such as heart rate sensors, blood oxygen sensors, and respiratory sensors as required according to the voice prompts. After the user confirms that the wearing is completed, the oxygen chamber closes and begins to assist the user in relieving the symptoms of altitude sickness.

[0064] Specifically, in step S100, the user's basic vital signs information includes the user's age, height and weight information. In steps S300 and S400, the user's real-time vital signs information and the user's vital signs information in continuous time intervals include the user's heart rate, blood oxygen saturation and respiratory rate.

[0065] It should be noted that, in step S200, the different levels of standby mode of the oxygen cabin are usually set to level 3, and the cabin temperature and cabin humidity are specifically set according to the altitude of the oxygen cabin.

[0066] Preferably, in step S400, the pre-trained adjustment model includes an oxygen chamber interior air pressure adjustment model based on the user's heart rate, blood oxygen saturation, and respiratory rate, and an oxygen chamber interior oxygen concentration adjustment model based on the user's heart rate, blood oxygen saturation, and respiratory rate;

[0067] The expression of the oxygen cabin air pressure adjustment model based on the user's heart rate, blood oxygen saturation and respiratory rate is:

[0068]

[0069] In expression (1), P0 represents the initial value of the air pressure in the oxygen chamber, h represents the user's height, w represents the user's weight, a represents the user's age, HR represents the user's heart rate, SpO2 represents the user's blood oxygen saturation, RF represents the user's respiratory rate, ∈ represents the error term of the oxygen chamber air pressure adjustment model, k1, k2, k3, k4, k5, and k6 represent the influence coefficients of the oxygen chamber air pressure adjustment model;

[0070] The expression of the oxygen concentration adjustment model in the oxygen cabin based on the user's heart rate, blood oxygen saturation and respiratory rate is:

[0071] C=C0+m1·h 3 +m2·w 2 +m3·ln(a)+m4·HR 2 +m5·(1-SpO2) 1.5 +m6·RF 0.5 +δ(2);

[0072] In expression (2), C0 represents the initial value of the oxygen concentration in the oxygen chamber, h represents the user's height, w represents the user's weight, a represents the user's age, HR represents the user's heart rate, SpO2 represents the user's blood oxygen saturation, RF represents the user's respiratory rate, δ represents the error term of the oxygen concentration adjustment model in the oxygen chamber, and m1, m2, m3, m4, m5, and m6 represent the influence coefficients of the oxygen concentration adjustment model in the oxygen chamber.

[0073] The user's vital sign information obtained in the continuous time interval is the user's heart rate, blood oxygen saturation and respiratory rate, and then the cabin air pressure and the cabin oxygen concentration are obtained based on the vital sign information. If the user's vital sign information in the continuous time interval is consistent with the cabin air pressure and the cabin oxygen concentration output by the pre-trained adjustment model, the cabin working environment value of the oxygen cabin is maintained at the current value; otherwise, the cabin working environment value of the oxygen cabin is adjusted until the user's vital sign information in the continuous time interval is consistent with the cabin air pressure and the cabin oxygen concentration output by the pre-trained adjustment model.

[0074] Preferably, the normal numerical indicators of heart rate, blood oxygen saturation, and respiratory rate set in the oxygen chamber are as follows:

[0075] A. Heart rate

[0076] Adults: The normal range is usually 60-100 beats / minute;

[0077] Infants and young children: The heart rate of a newborn is 120-140 beats / minute; the heart rate of an infant under 1 year old is 110-130 beats / minute;

[0078] Children: The heart rate of children aged 2-3 is 100-120 beats / minute; the heart rate of children aged 4-7 is 80-100 beats / minute; the heart rate of children aged 8-14 is 70-90 beats / minute.

[0079] B. Blood oxygen saturation

[0080] Arterial oxygen saturation is generally between 95% and 100%.

[0081] C. Respiratory rate

[0082] Adults: The normal range is generally 12-20 times / minute.

[0083] Infants and young children: The respiratory rate of a newborn can reach 40-60 times / minute; the respiratory rate of an infant under 1 year old is 30-40 times / minute.

[0084] Children: The respiratory rate of children aged 2-3 years is 25-30 times / minute; the respiratory rate of children aged 4-7 years is 20-25 times / minute; the respiratory rate of children aged 8-14 years is 18-20 times / minute.

[0085] Correspondingly, k1, k2, k3, k4, k5, and k6 are 0.001, 0.002, 0.003, 0.01, 0.05, and 0.001 respectively; m1, m2, m3, m4, m5, and m6 are 0.001, 0.002, 0.003, 0.02, 0.03, and 0.002 respectively. The error terms ò and δ are set according to the altitude and model of the oxygen chamber.

[0086] In one embodiment of the present application, the adjustment process of the oxygen chamber internal pressure adjustment model based on the user's heart rate, blood oxygen saturation and respiratory rate and the oxygen concentration adjustment model based on the user's heart rate, blood oxygen saturation and respiratory rate includes:

[0087] If the user's heart rate in any of the consecutive time intervals increases compared to the heart rate in the previous time interval, the air pressure and oxygen concentration in the oxygen chamber will be increased; otherwise, the air pressure and oxygen concentration in the oxygen chamber will be reduced;

[0088] If the user's blood oxygen saturation in any time interval within the consecutive time intervals is higher than that in the previous time interval, the air pressure and oxygen concentration in the oxygen cabin will be reduced; otherwise, the air pressure and oxygen concentration in the oxygen cabin will be increased;

[0089] If the user's breathing rate in any time interval within the consecutive time intervals is higher than the heart rate in the previous time interval, the air pressure and oxygen concentration in the oxygen chamber will be increased. Otherwise, the air pressure and oxygen concentration in the oxygen chamber will be reduced.

[0090] During specific use, during the oxygen chamber pressure stabilization stage, the early control uses any one of the user's heart rate, blood oxygen saturation and respiratory rate as the adjustment dependent variable, which can quickly adjust the user's body index and reduce the discomfort of altitude sickness.

[0091] In one embodiment of the present application, the adjustment process of the oxygen chamber internal pressure adjustment model based on the user's heart rate, blood oxygen saturation and respiratory rate and the oxygen chamber internal oxygen concentration adjustment model based on the user's heart rate, blood oxygen saturation and respiratory rate further includes:

[0093] If the user's heart rate in any of the consecutive time intervals increases compared to the heart rate in the previous time interval, and the user's blood oxygen concentration decreases compared to the blood oxygen concentration in the previous time interval, the air pressure and oxygen concentration in the oxygen chamber are increased;

[0094] If the user's heart rate in any of the consecutive time intervals decreases compared to the heart rate in the previous time interval, and the user's blood oxygen concentration increases compared to the blood oxygen concentration in the previous time interval, the air pressure and oxygen concentration in the oxygen chamber are reduced;

[0101] In one embodiment of the present application, the adjustment process of the oxygen chamber internal pressure adjustment model based on the user's heart rate, blood oxygen saturation and respiratory rate and the oxygen chamber internal oxygen concentration adjustment model based on the user's heart rate, blood oxygen saturation and respiratory rate further includes:

[0102] If the user's blood oxygen concentration and respiratory rate in any time interval within the consecutive time interval are higher than the blood oxygen concentration and respiratory rate in the previous time interval, and k5·(1-SpO2) 2 The reduction is greater than k6·RF 3 Increase in m5·(1-SpO2) 1.5 The reduction is greater than m6·RF 0.5 If the increase in the oxygen chamber pressure and oxygen concentration is greater than that in the previous time interval, the oxygen chamber pressure and oxygen concentration will be reduced; if the blood oxygen concentration and respiratory rate of the user in any time interval of the continuous time interval are higher than those in the previous time interval, and k5·(1-SpO2) 2 The reduction is less than k6·RF 3 Increase in m5·(1-SpO2) 1.5 The reduction is less than m6·RF 0.5 The increase in the oxygen pressure and oxygen concentration in the oxygen cabin will increase;

[0103] If the user's blood oxygen concentration and respiratory rate in any time interval of the consecutive time interval are lower than the blood oxygen concentration and respiratory rate in the previous time interval, and k5·(1-SpO2) 2 The increase is greater than k6·RF 3 Reduction in m5·(1-SpO2) 1.5 The increase is greater than m6·RF 0.5If the amount of decrease is greater than that of the oxygen concentration in the oxygen chamber, the air pressure and oxygen concentration in the oxygen chamber will be increased; if the blood oxygen concentration and respiratory rate of the user in any time interval of the continuous time interval are higher than those in the previous time interval, and k5·(1-SpO2) 2 The increase is less than k6·RF 3 Reduction in m5·(1-SpO2) 1.5 The increase is less than m6·RF 0.5 The decrease in the oxygen pressure and oxygen concentration in the oxygen cabin will be reduced;
