During use, it is key to monitor the user's physical condition in real time and make corresponding adjustments based on the monitoring results. However, with the rapid development of sensor technology and smart terminal technology, most of the electronic medical testing equipment on the market currently has a single function and is difficult to meet the needs of real-time monitoring of multiple physiological indicators.

[0024] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0025] The following describes the implementation methods of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The present application can also be implemented or applied through other different specific implementation methods, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that, in the absence of conflict, the following embodiments and the features in the embodiments can be combined with each other. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work belong to the scope of protection of the present application.

[0026] An embodiment of the present invention provides a human multi-vital signs monitoring system for a micro-pressure oxygen chamber. The system can be installed in the micro-pressure oxygen chamber and can automatically start the vital signs monitoring function after the target enters the oxygen chamber and wears the sensor cuff, and continuously monitor and record the target's multiple vital signs including respiratory rate, heart rate, blood oxygen concentration, and body temperature.

[0027] In an embodiment of the present invention, a method for monitoring physiological indicators in a microbaric oxygen chamber is provided. Figure 1 As shown, the method includes:

[0028] Step S101: loading a physiological index monitoring system including a radar sensor module and a finger cuff module into a micro-pressure oxygen chamber, wherein the finger cuff module includes a temperature module and a blood oxygen detection module;

[0029] Step S102: starting the physiological index monitoring system, and continuously detecting whether there is a moving target in the set area through the radar sensor module. If there is a moving target, the physiological index monitoring system is triggered to enter the working state;

[0030] Step S103: Detect whether the target is wearing a finger cuff through the temperature module of the finger cuff module. If the target is wearing a finger cuff, monitor the target's physiological indicators through the radar sensor module, the temperature module and the blood oxygen detection module, and output the generated data as physiological indicator data. If the target is not wearing a finger cuff, issue a prompt message;

[0031] Step S104: setting 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 sleeve, the physiological index monitoring system is restored to a standby state.

[0032] like Figure 2 As shown, the workflow of the physiological index monitoring system applied to the micropressure oxygen chamber is as follows:

[0033] 1. The system starts and is in standby mode;

[0034] 2. When the target to be detected enters the monitoring area of ​​the oxygen chamber, 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 steadily, the oximeter module detects a signal, and the radar sensor does not detect the target movement, it is considered that the target has sat stably in the detection area and put on the finger cuff. The system enters the vital signs monitoring working state, starts monitoring and recording the target's vital signs, and uploads the data to the sensor;

[0036] 4. When the body temperature monitoring module detects a large fluctuation and the detected body temperature or blood oxygen value is abnormal, it is considered that the target is not wearing the finger sleeve correctly, and a reminder message is issued to remind the target to wear the finger sleeve correctly;

[0037] 5. When it is detected that the target is not wearing the fingertip, and no movement is detected for a period of time after the target is detected to be moving, it is considered that the target has completed the measurement and left the oxygen chamber, and the system returns to standby mode.

[0038] Specifically, Figure 3 As shown in the figure, the system mainly consists of three parts: radar sensor module, finger sleeve module and host computer. The radar sensor module and finger sleeve module are connected to and controlled by the host computer, and the host computer is connected to the server to facilitate data transmission and external control.

[0039] In specific implementation, in order to determine whether the target has entered the micro-pressure oxygen chamber by whether the target is moving, the following steps are performed to continuously detect whether there is a moving target in the set area through the radar sensor module:

[0040] Using the analog I / Q demodulation method, the radar sensor module obtains the quadrature component Q(t) and the in-phase component I(t) within a certain time period t; the maximum signal value Q of the quadrature component Q(t) within a certain time period t is obtained. 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 signal fluctuation of the orthogonal component Q(t) within a certain period of time t is calculated, and the maximum signal value I max and minimum signal value I min The amplitude ΔI of the signal fluctuation of the in-phase component I(t) within a certain period of time t is calculated, where ΔI=|I max -I min |, ΔQ=|Q max -Q min |; Set the judgment threshold α. If ΔI>α or ΔQ>α, it is judged that there is a moving target. Otherwise, it is judged that there is no moving target.

[0041] Specifically, the radar sensor module is mainly used to determine whether there is a target moving in the area and to detect the target's breathing rate. The radar sensor uses an analog I / Q demodulation method and can obtain two signals, I(t) and Q(t). Based on the closed environment of the micro-pressure oxygen chamber, it is possible to determine whether a target is moving by measuring the amplitude of the fluctuations of the I-channel (in-phase component) or Q-channel (orthogonal component) signals within a certain period of time (the I-channel and Q-channel judge the direction of target movement in the same way). Taking the I-channel judgment as an example, within a certain period of time t, the maximum value of the I-channel signal is Imax and the minimum value is Imin. The amplitude of the signal fluctuation within this period of time is defined as ΔI=|I max -Imin |, if the judgment threshold is α, then if ΔI>α, it is judged that there is a target moving in the monitoring area.

[0042] In specific implementation, the following steps are performed to detect whether the target is wearing a finger cuff through the temperature module of the finger cuff module:

[0043] The ambient temperature, the first duration, the first temperature difference, the second duration and the second temperature difference of the microcompression oxygen chamber are set; the real-time temperature of the microcompression oxygen chamber is continuously detected by the temperature module; if the difference of the real-time temperature within a certain time period is greater than the first temperature difference and the duration is within the first duration, it is judged that the temperature fluctuates, otherwise, it is judged that the temperature does not fluctuate; if the temperature does not fluctuate, it is judged that the target does not wear the finger cuff; if the temperature fluctuates, it is judged whether the difference of the real-time temperature is less than the second temperature difference and the duration is greater than the second duration within the next certain time period, if so, it is judged that the temperature remains stable, if not, it is judged that the temperature does not remain stable; if the temperature remains stable, it is judged that the target has worn the finger cuff, if the temperature does not remain stable, it is judged that the target does not wear the finger cuff.

[0044] In specific implementation, the following steps are performed to monitor the physiological indicators of the target through the radar sensor module, the temperature module and the blood oxygen detection module, and the generated data is output as the physiological indicator data:

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

[0046] In specific implementation, the following steps are performed to obtain the radar phase signal within a certain period of time t from the radar sensor module, and the target's breathing rate is calculated by the radar phase signal:

[0047] Using the analog I / Q demodulation method, the orthogonal component Q(t) and the in-phase component I(t) within a certain time period t are obtained through the radar sensor module; the radar phase signal phase within a certain time period t is calculated based on the orthogonal component Q(t) and the in-phase component I(t) within a certain time period t, where the radar phase signal Perform Fourier transform on the radar phase signal phase to generate a spectrum within a certain time period t; set the frequency range, obtain the frequency component with the largest amplitude in the spectrum within the frequency range of the spectrum, and use the frequency component with the largest amplitude as the target's breathing frequency f br ; through the target breathing rate f brCalculate the target breathing rate, where breathing rate = 60 × f br times / minute.

[0048] Specifically, the breathing rate can be obtained by analyzing the radar phase signal within a certain period of time T. The calculation formula of the radar phase signal is: Then perform Fourier transform on the phase signal to obtain the spectrum within the time period, and compare the amplitudes of the frequency components below 1 Hz in the spectrum. The frequency component with the largest amplitude can be considered as the target breathing frequency f br , we can further calculate the target's breathing rate to be 60×f br times / minute.

[0049] In specific implementation, the following steps are performed to obtain the target's blood oxygen concentration value and the target's heart rate value through the blood oxygen detection module:

[0050] The light conduction intensity passing through the tissue bed is obtained from the photoelectric sensor in the blood oxygen detection module, and the target blood oxygen concentration value is obtained by analyzing the light conduction intensity; the detection waveform data is obtained from the photoelectric sensor in the blood oxygen detection module, and the detection waveform data is analyzed in time and frequency to generate a spectrum diagram; the heart rate frequency range is set, and within the heart rate frequency range of the spectrum diagram, the amplitude of the frequency component is compared, and the frequency component with the largest amplitude is taken as the target heartbeat frequency f hr , through the heart rate f hr Calculate the target heart rate value, where heart rate value = 60×f hr times / minute.

[0051] Specifically, the finger cuff module integrates a temperature detection module and a blood oxygen detection module. The blood oxygen detection module measures the light conduction intensity through the tissue bed through a photoelectric sensor, and then analyzes and obtains the target's blood oxygen concentration value. At the same time, the spectrum can also be obtained by performing Fourier transform time-frequency analysis on the detected waveform. Then compare the amplitudes of the frequency components in the frequency range of 0.8Hz-3Hz in the spectrum, and consider the frequency component with the largest amplitude to be the target's heart rate f hr , and calculate the target heart rate value to be 60×f hr times / minute. When the target is not wearing the cuff, the temperature monitored by the temperature sensor is the ambient temperature. Usually the ambient temperature in the oxygen chamber environment is set to around 26 degrees Celsius. When the target wears the cuff, the system will detect a large temperature fluctuation. After detecting the large fluctuation, if the temperature remains stable again, it is determined that the target has worn the cuff correctly.

[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. If the difference T between the maximum and minimum values ​​of the temperature data (real-time temperature) detected within 1 second is max -T min >3℃, it is considered that a large fluctuation is detected; when the difference between the maximum and minimum temperature values ​​detected for 3 consecutive seconds is greater than T max -T min <0.5℃, the temperature detection can be considered to have entered a stable state.

[0053] In specific implementation, the following steps are performed to control the radar sensor module and the finger sleeve module through the host computer:

[0054] The radar sensor module and the finger sleeve module are controlled by a host computer connected to both the radar sensor module and the finger sleeve module; and the physiological index data are transmitted to a server by the host computer.

[0055] During the working process, the system will also perform abnormal detection and analysis on the target's physical condition, and promptly issue an alarm and notify medical staff when an abnormal event is found. For example, the target's blood oxygen concentration continues to be lower than a certain threshold, the target's heart rate suddenly rises to a higher level, the target's respiratory rate is too low, etc.

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

[0057] 1. The radar is placed on the upper right side of the seat in the oxygen cabin, and the main lobe of the radar antenna points to the chest of the target after the target sits down. The time window for detecting motion is set to 1s, the step length is 0.5s, and the detection threshold is 0.1.

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

[0059] 3. When the target wears the finger cuff, the temperature sensor detects a temperature change of more than 3 degrees Celsius, and the blood oxygen module detects waveform data, the system starts 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 the 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, and the processor implements any of the above-mentioned device methods when executing the computer program.
