Description

Technical Field

[0001] This invention relates to the field of human physiological indicator monitoring technology, and in particular to a method, device, equipment and medium for monitoring physiological indicators applied in a micro-hyperbaric oxygen chamber. Background Technology

[0002] A microbaric oxygen chamber is a health care device specifically designed to provide a micropressure environment, aiming to create a safe and comfortable oxygen inhalation experience for users, while also promoting relaxation and relieving fatigue. Real-time monitoring of the user's physical condition and adjustments based on the monitoring results are crucial during use. However, with the rapid development of sensor technology and smart terminal technology, most electronic medical testing devices on the market currently offer limited functionality and struggle to meet the demands of real-time monitoring of multiple physiological indicators. Furthermore, these devices exhibit significant gaps in sensitivity, accuracy, and practical operational requirements, lacking the ability to provide real-time, accurate, and effective monitoring and early warning of the user's health status.

[0003] Current hypobaric oxygen chambers typically monitor physiological indicators using devices such as wristbands. However, monitoring is impossible if the user does not wear these devices. This reliance means that existing physiological indicator monitoring equipment cannot fully meet user needs. Therefore, there is an urgent need for a multifunctional real-time monitoring system specifically designed for hypobaric oxygen chamber environments. This system should not only monitor multiple physiological indicators of the user and transmit the data to a central server in real time, but also detect any abnormalities in the user's vital signs to ensure the user's health and safety. Summary of the Invention

[0004] In view of this, embodiments of the present invention provide a method for monitoring physiological indicators in a microhyperbaric oxygen chamber, to solve the technical problem in the prior art that physiological indicator monitoring cannot be completed when the user is not wearing the relevant equipment. The method includes:

[0005] A physiological indicator monitoring system, including a radar sensing module and a finger sleeve module, is mounted on a micro-hyperbaric oxygen chamber. The finger sleeve module includes a temperature module and a blood oxygen detection module.

[0006] The physiological indicator monitoring system is activated, and the radar sensing module continuously detects whether there are moving targets in the set area. If there are, the physiological indicator monitoring system is triggered to enter the working state.

[0007] The temperature module of the finger cot module detects whether the target is wearing a finger cot. If the target is wearing a finger cot, the target's physiological indicators are monitored by the radar sensing module, the temperature module and the blood oxygen detection module, and the generated data is output as physiological indicator data. If the target is not wearing a finger cot, a prompt message is issued.

[0008] A duration threshold is set. If the target remains inactive for longer than the duration threshold and the target is not wearing a finger cot, the physiological indicator monitoring system is restored to standby mode.

[0009] This invention also provides a physiological indicator monitoring device for use in a microhyperbaric oxygen chamber, to solve the technical problem in the prior art that physiological indicator monitoring cannot be completed when the user is not wearing the relevant equipment.

[0011] The motion detection module is used to activate the physiological indicator monitoring system. It continuously detects whether there is a moving target in the set area through the radar sensor module. If there is, it triggers the physiological indicator monitoring system to enter the working state.

[0012] The finger cot wearing detection module is used to detect whether the target is wearing a finger cot through the temperature module of the finger cot module. If the target is wearing a finger cot, the target's physiological indicators are monitored through the radar sensing module, the temperature module and the blood oxygen detection module, and the generated data is output as physiological indicator data. If the target is not wearing a finger cot, a prompt message is issued.

[0013] The standby module is used to set a duration threshold. If the target is inactive for a period of time exceeding the duration threshold and the target is not wearing a finger cot, the physiological indicator monitoring system is restored to standby mode.

[0024] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0025] The following specific examples illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. This application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] This invention provides a human multi-vital sign monitoring system for a micro-hyperbaric oxygen chamber. The system can be installed in a micro-hyperbaric oxygen chamber and can automatically start the vital sign monitoring function after the target enters the oxygen chamber and puts on the sensor finger cot. It continuously monitors and records multiple vital signs of the target, including respiratory rate, heart rate, blood oxygen concentration, and body temperature.

[0027] In this embodiment of the invention, a method for monitoring physiological indicators applied in a microhyperbaric oxygen chamber is provided, such as... Figure 1 As shown, the method includes:

[0028] Step S101: The physiological indicator monitoring system, including a radar sensing module and a finger sleeve module, is mounted on the micro-hyperbaric oxygen chamber. The finger sleeve module includes a temperature module and a blood oxygen detection module.

[0029] Step S102: Start the physiological indicator monitoring system and continuously detect whether there is a moving target in the set area through the radar sensing module. If there is, trigger the physiological indicator monitoring system to enter the working state.

[0030] Step S103: The temperature module of the finger cot module detects whether the target is wearing a finger cot. If the target is wearing a finger cot, the radar sensing module, temperature module and blood oxygen detection module monitor the target's physiological indicators and output the generated data as physiological indicator data. If the target is not wearing a finger cot, a prompt message is issued.

[0031] Step S104: Set a duration threshold. If the target remains inactive for longer than the duration threshold and the target is not wearing a finger cot, restore the physiological indicator monitoring system to standby mode.

[0032] like Figure 2 As shown, the workflow of the physiological indicator monitoring system applied in a hypobaric oxygen chamber is as follows:

[0033] 1. The system starts up and enters standby mode;

[0034] 2. When the target to be detected enters the oxygen chamber monitoring area, the radar sensor will detect the target movement and trigger the system to enter the working state;

[0035] 3. When the system detects a large temperature fluctuation, the temperature changes stabilize, the pulse oximeter module detects a signal, and the radar sensor does not detect target movement, it is assumed that the target has been sitting stably in the detection area and wearing the finger cot. The system then enters the vital signs monitoring state, begins to monitor and record the target's vital signs, and uploads the data to the sensor.

[0036] 4. If the body temperature monitoring module detects a large fluctuation and the detected body temperature or blood oxygen value is abnormal, it will assume that the target is not wearing the finger cot correctly and will issue a reminder message to remind the target to wear the finger cot correctly.

[0037] 5. If the target is not wearing a finger cot and no further movement is detected after a period of time following the detection of the target's movement, it is considered that the target has completed the measurement and left the oxygen chamber, and the system returns to standby mode.

[0038] Specifically, such as Figure 3 As shown, this system mainly consists of three parts: a radar sensing module, a finger sleeve module, and a host computer. The radar sensing module and the finger sleeve module are connected to and controlled by the host computer, which in turn connects to a server for data transmission and external control.

[0039] In practice, to determine whether a target has entered the micro-pressure oxygen chamber by observing whether the target is moving, the following steps are taken to continuously detect the presence of moving targets within a designated area using a radar sensing module:

[0040] Using an analog I / Q demodulation method, the quadrature component Q(t) and the in-phase component I(t) within a certain time period t are acquired through a radar sensing module; the maximum signal value Q of the quadrature component Q(t) within the certain time period t is also acquired. max Minimum signal value Q min The maximum signal value I of the in-phase component I(t) max Minimum signal value I min ; through the maximum signal value Q max and minimum signal value Q min The amplitude ΔQ of the orthogonal component Q(t) within a certain time period t is calculated, and then passed through the maximum signal value I. max and minimum signal value I min The amplitude ΔI of the in-phase component I(t) within a certain time period t is calculated, where ΔI = |I max -I min |,ΔQ=|Q max -Q min |; Set a judgment threshold α. If ΔI>α or ΔQ>α, determine that there is a moving target; otherwise, determine that there is no moving target.

[0041] Specifically, the radar sensing module is mainly used to determine whether there is a moving target in the area and to detect the target's breathing rate. The radar sensor uses analog I / Q demodulation to acquire two signals, I(t) and Q(t). Based on the closed environment of the micro-hyperbaric oxygen chamber, the presence of a moving target can be determined by measuring the amplitude of the fluctuations in either the I-channel (in-phase component) or Q-channel (quadrature component) signals over a certain time period (I and Q signals indicate the same direction of target movement). Taking I-channel detection as an example, within a certain time period t, the maximum value of the I-channel signal is Imax, and the minimum value is Imin. The amplitude of the signal fluctuation during this time period is defined as ΔI = |Imax|min. max -Imin If the threshold is α, then if ΔI > α, then it is determined that there is a target moving within the monitoring area.

[0042] In practice, the following steps are used to detect whether the target is wearing a finger cot via the temperature module of the finger cot module:

[0043] The system sets the ambient temperature, first duration, first temperature difference, second duration, and second temperature difference of the micro-pressure oxygen chamber. It continuously monitors the real-time temperature of the micro-pressure oxygen chamber using a temperature module. If the real-time temperature difference within a certain time period is greater than the first temperature difference and the duration is within the first duration, the temperature is considered to have fluctuated; otherwise, the temperature is considered not to have fluctuated. If the temperature does not fluctuate, the target is considered not to be wearing finger cots. If the temperature fluctuates, it is determined whether, within the next certain time period, the real-time temperature difference is less than the second temperature difference and the duration is greater than the second duration. If this condition is met, the temperature is considered to have remained stable; otherwise, the temperature is considered not to have remained stable. If the temperature remains stable, the target is considered to be wearing finger cots; otherwise, the target is considered not to be wearing finger cots.

[0044] In practice, the following steps are used to monitor the target's physiological indicators through the radar sensing module, temperature module, and blood oxygen detection module, and output the generated data as physiological indicator data:

[0045] The radar phase signal within a certain time period t is acquired from the radar sensing module, and the target's respiratory rate is calculated from the radar phase signal; the target's blood oxygen concentration and heart rate are acquired from the blood oxygen detection module; the target's body temperature is acquired from the temperature module; and the respiratory rate, blood oxygen concentration, heart rate, and body temperature are output as physiological indicator data.

[0046] In practice, the following steps are used to acquire the radar phase signal within a certain time period t from the radar sensing module, and then calculate the target's breathing rate using the radar phase signal:

[0047] Using an analog I / Q demodulation method, the quadrature component Q(t) and the in-phase component I(t) within a certain time period t are acquired through the radar sensing module. Based on the quadrature component Q(t) and the in-phase component I(t) within the time period t, the radar phase signal (phase) within that time period t is calculated. Perform a Fourier transform on the radar phase signal to generate a spectrum over a certain time period t. Define a frequency range, and within that range, identify the frequency component with the largest amplitude. Use this frequency component as the target's breathing frequency f. br ; through the target's breathing rate f brThe target's respiratory rate was calculated, where respiratory rate = 60 × f br times per minute.

[0048] Specifically, the respiratory rate can be obtained by analyzing the radar phase signal over a certain time period T. The formula for calculating the radar phase signal is as follows: Next, a Fourier transform is performed on the phase signal to obtain the spectrum for that time period, and the amplitudes of the frequency components below 1 Hz in the spectrum are compared. The frequency component with the largest amplitude can be considered as the target breathing frequency f. br This allows us to calculate the target's respiratory rate as 60 × f. br times per minute.

[0049] In practice, the following steps are used to obtain the target's blood oxygen concentration and heart rate values ​​through the blood oxygen detection module:

[0050] The light transmission intensity passing through the tissue bed is acquired from the photoelectric sensor in the blood oxygen detection module. The target blood oxygen concentration value is obtained by analyzing the light transmission intensity. Waveform data is acquired from the photoelectric sensor in the blood oxygen detection module, and time-frequency analysis is performed on the waveform data to generate a spectrum. A heart rate frequency range is defined. Within the heart rate frequency range of the spectrum, the amplitudes of the frequency components are compared, and the frequency component with the largest amplitude is taken as the target heart rate f. hr Through heart rate f hr The target's heart rate value is calculated, where heart rate value = 60 × f hr times per minute.

[0051] Specifically, the finger sleeve module integrates a temperature detection module and a blood oxygen detection module. The blood oxygen detection module uses a photoelectric sensor to measure the intensity of light transmission through the tissue bed, and then analyzes and obtains the target's blood oxygen concentration value. Simultaneously, a frequency spectrum is obtained by performing Fourier transform time-frequency analysis on the detected waveform. Then, by comparing the amplitude of frequency components in the 0.8Hz-3Hz frequency range in the frequency spectrum, the frequency component with the largest amplitude is considered to be the target's heart rate f. hr And calculate the target heart rate as 60 × f hr Frequency per minute. When the target is not wearing finger cots, the temperature sensor monitors the ambient temperature. Typically, the ambient temperature in an oxygen chamber is set to around 26 degrees Celsius. When the target puts on finger cots, the system detects a significant temperature fluctuation. Once the temperature stabilizes after detecting the large fluctuation, the system determines that the target is correctly wearing the finger cots.

[0052] In some embodiments, the first duration is set to 1 second, the first temperature difference is set to 3°C, the second duration is set to 3 seconds, and the second temperature difference is set to 0.5°C. Then, if the difference T between the maximum and minimum values ​​of the temperature data (real-time temperature) detected within 1 second... max -T min If the temperature is >3℃, it can be considered that a large fluctuation has been detected; when the difference T between the maximum and minimum temperature values ​​detected for 3 consecutive seconds is... max -T min If the temperature is less than 0.5℃, the temperature detection can be considered to have entered a stable state.

[0053] In practice, the following steps are used to control the radar sensing module and the finger sleeve module via a host computer:

[0054] The radar sensing module and the finger sleeve module are controlled by a host computer that is connected to both the radar sensing module and the finger sleeve module; physiological indicator data are transmitted to the server via the host computer.

[0055] During operation, the system also performs anomaly detection and analysis on the target's vital signs. When an abnormal event is detected, it will promptly issue an alarm to notify medical personnel. For example, the target's blood oxygen concentration may remain below a certain threshold, the target's heart rate may suddenly rise to a high level, or the target's respiratory rate may be too low.

[0056] In one embodiment, detecting physiological indicator data of a target using a physiological indicator monitoring system includes the following steps:

[0057] 1. The radar is positioned to the upper right of the seat in the oxygen chamber, with the radar antenna's main lobe pointing towards the target's chest after they have sat down. The motion detection time window is set to 1 second, the step size to 0.5 seconds, and the detection threshold to 0.1.

[0058] 2. When a target enters the detection range, the radar detects the target movement and enters the working state.

[0059] 3. When the target puts on the finger cot, the temperature sensor detects a temperature change of more than 3 degrees Celsius, and the blood oxygen module detects waveform data, the system begins to monitor and record vital signs.

[0060] 4. When the temperature sensor detects a temperature change of more than 3 degrees Celsius, the radar sensor detects movement of the target and starts timing after it returns to calm. If no object movement is detected again within 10 seconds, it is considered that the target has left the detection area, and the system returns to standby mode.

[0061] In this embodiment, a computer device is provided, such as... Figure 4As shown, it includes a memory 401, a processor 402, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements any of the above-described apparatus methods.

[0062] Specifically, the computer device can be a computer terminal, a server, or a similar computing device.

[0063] In this embodiment, a computer-readable storage medium is provided, which stores a computer program that executes any of the above-described methods for monitoring physiological indicators applied to a microhyperbaric oxygen chamber.

[0064] Specifically, computer-readable storage media, including both permanent and non-permanent, removable and non-removable media, can store information using any method or technology.
