These devices often require users to wear specialized air bags or straps, making operation relatively cumbersome. This is particularly true in specific scenarios, such as exercise and sleep. Traditional mercury sphygmomanometers typically rely on specialized medical personnel for operation.

[0011] In order to make the purpose, features, and advantages of the invention of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0012] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of this application, the meaning of "plurality" is two or more, unless otherwise clearly specified.

[0013] In order to solve the problem of low convenience of blood pressure measurement in the related art, the first embodiment of the present application provides a smart glasses, such as Figure 1This is a schematic diagram of the structure of smart glasses provided in this embodiment. The smart glasses 1 include a blood pressure measurement system integrated into the glasses body. The blood pressure measurement system includes a controller 2, an air pressure pump 3, and an air bag 4. The controller 2 is used to:

[0014] When a blood pressure measurement instruction is received, the air pressure pump 3 is controlled to enter the working state; when the air pressure pump 3 enters the working state, it is used to inflate the airbag 4; when the pressure value of the airbag 4 reaches the preset pressure value, the air pressure pump 3 is controlled to enter the cut-off state, and the airbag 4 is controlled to enter the exhaust state; according to the real-time pressure value of the airbag 4 in the exhaust state, the blood pressure data of the subject is obtained.

[0015] Specifically, in this embodiment, a blood pressure measurement system is provided within the smart glasses 1. This system includes an air pressure pump 3 and an air bag 4. Therefore, when using the smart glasses 1 for blood pressure measurement, there is no need to wear an additional air bag (such as a cuff). Blood pressure measurement can be performed simply by securing the smart glasses 1 to the subject's arm and ensuring that the air bag 4 is in contact with the skin. The main body of the smart glasses 1 can be designed using lightweight materials to ensure wearing comfort.

[0016] The measurement process is as follows: During test preparation, the subject should remain relaxed before the measurement, with their arm relaxed and elevated above their heart level. The smart glasses 1 are secured to the subject's upper arm, for example, via connector 6, typically above the elbow joint and near heart level. Ensure that the airbag 4 in the blood pressure measurement system is in close contact with the skin, but not too tight. After these preparations are completed, the controller 2 controls the air pump 3 to start according to the blood pressure measurement instruction. The blood pressure measurement instruction received by the controller 2 can be a user-input start-up instruction or a command generated through automatic detection. The user-input instruction can be generated directly through a corresponding function button on the smart glasses 1 or a command issued by a terminal, which is transmitted to the controller 2 in the blood pressure measurement system via wireless communication. The automatic detection method can automatically detect the wearing status through sensors, such as pressure sensors or skin contact sensors, and generate a blood pressure measurement instruction when the smart glasses 1 are correctly worn on the subject's arm. Upon detecting that the smart glasses 1 are correctly worn on the subject's arm, an indication signal is generated to confirm the blood pressure measurement. After receiving the blood pressure measurement instruction, the controller 2 will control the air pressure pump 3 to work to inflate the airbag 4, increase the pressure in the airbag 4, until the pressure value of the airbag 4 reaches the preset pressure value. When the pressure value of the airbag 4 reaches the preset pressure value, it will expand and press on the artery, temporarily blocking the blood flow. After that, the air pressure pump 3 will be controlled to stop working and the airbag 4 will be controlled to enter the exhaust state. During this period, the pressure change of the airbag 4 can be detected, for example, using a sensor that detects pressure data (such as Figure 1The pressure sensor 5 detects pressure changes in the airbag 4. The pressure sensor can be mounted on the airbag 4, ensuring good contact with the skin by fitting the airbag 4 against the skin, thereby improving monitoring accuracy. The pressure readings of the airbag 4 are then used to analyze the subject's blood pressure data, enabling quick and convenient blood pressure measurement.

[0017] In addition, the smart glasses 1 also include a communication module, which can transmit the blood pressure data to a user terminal such as a smartphone or the cloud through wireless communication technologies such as Wi-Fi, Bluetooth, NFC, etc. after obtaining the measurement data, providing users with a flexible communication connection method, so that users can view and analyze health data at any time.

[0018] In addition to the communication module, the smart glasses 1 may also be equipped with functional modules such as a display module and a voice module to provide users with different interactive functions.

[0019] Furthermore, in some implementations of this embodiment, the blood pressure measurement system is provided on the temple of the smart glasses 1. The blood pressure measurement system further includes a connector 6, both ends of which are connected to the outside of the temple, and the airbag 4 is provided on the inside of the temple.

[0020] Furthermore, in some other implementations of this embodiment, the blood pressure measurement system is provided in the frame of the smart glasses 1 .

[0021] Specifically, in this embodiment, the blood pressure measurement system can be set at multiple locations of the smart glasses 1, such as the inside of the glasses leg and the frame, as long as the airbag 4 is in good contact with the skin. Figure 1 Taking the setup of the blood pressure measurement system as an example, the air pressure pump 3 and air bag 4 are integrated into the temple of the smart glasses 1, with the temple serving as a support structure. The air bag 4 is secured to the subject's arm with a connector 6, ensuring a close fit between the air bag 4 and the skin. The connector 6, such as a tie cord, is placed on the outside of the temple, while the air bag 4 is placed on the inside. Furthermore, the blood pressure measurement system can be configured with one or more components as needed.

[0022] In some implementations of this embodiment, the blood pressure measurement system also includes a motor to control the air pressure pump 3 to enter a working state, including: obtaining the inflation pressure range corresponding to the object under test; generating a drive signal to the motor based on the pressure value and inflation pressure range of the airbag 4 in the inflated state; the drive signal is used to adjust the operating state of the motor, and when the motor enters the working state, it is used to control the air pressure pump 3 to enter the working state.

[0023] Specifically, in this embodiment, the blood pressure measurement system is further provided with a micro motor for activating the air pump according to the drive signal of the controller 2. While the control motor outputs the drive signal to the air pump 3, the controller 2 adjusts the drive signal according to the pressure value in the airbag 4 to adjust the operating state of the motor. For example, the drive signal is first generated to control the motor to start working to activate the air pump 3. During the operation of the air pump 3, the drive signal is adjusted according to the real-time pressure value of the airbag 4 collected by the sensor monitoring the pressure of the airbag 4 and the preset inflation pressure range to adjust the speed of the motor in real time to ensure that the pressure of the airbag 4 increases steadily to the preset inflation pressure range. When the pressure of the airbag 4 reaches the preset pressure range, the controller 2 stops generating the drive signal.

[0024] The inflation pressure range can be a universal pressure range, for example, ensuring that the pressure in the airbag 4 exceeds the normal systolic blood pressure. This ensures that the airbag 4 expands and temporarily blocks blood flow in the arm artery. It can also be personalized based on the subject being tested. For example, for a wearer of the smart glasses 1, an inflation pressure higher than their known systolic blood pressure can be selected based on their previous blood pressure records. For example, if their blood pressure is typically 120 / 80 mmHg, the airbag 4 can be inflated to 160 mmHg or higher. For other subjects, a universal inflation range, such as 160 to 180 mmHg, can be used to ensure that blood flow is compressed. Alternatively, the inflation range can be adjusted based on relevant anthropomorphic parameters such as weight, height, and age to ensure measurement accuracy and comfort. The correct inflation pressure can provide more effective and reliable blood pressure readings. If the initial measurement results are found to be inconsistent with expectations, the measurement can be repeated and the inflation pressure adjusted based on the initial measurement results.

[0025] In some embodiments of this embodiment, the blood pressure measurement system also includes an air valve connected to the airbag 4 to control the airbag 4 to enter the exhaust state, including: outputting an opening drive signal to the air valve; the opening drive signal is used to instruct the air valve to switch from a closed state to an open state, and when the air valve is in the open state, the airbag 4 enters the exhaust state.

[0026] Specifically, in this embodiment, the blood pressure measurement system also includes an air valve. The air valve can be located near the air pump 3 and the air bag 4. For example, the air valve is connected to the air bag 4 via a pipeline, and the air pump 3 is also connected to the air valve via a pipeline, ensuring that the flow of gas can be quickly and effectively controlled. The air valve can control the inflation and deflation of the air bag 4. During inflation, the air valve is closed, and the air pump 3 operates to inject air into the air bag 4. During deflation, the air valve opens, and the gas in the air bag 4 is released. The air valve can be an electromagnetic air valve, and its opening and closing can be controlled by the controller 2.

[0027] Furthermore, in some implementations of this embodiment, the controller 2 is also used to: if the real-time pressure value does not match the corresponding target pressure value, obtain the difference between the real-time pressure value and the target pressure value; if the difference meets the preset threshold range, generate a target drive signal to the air valve based on the difference.

[0028] Specifically, during the deflation process, the valve can adjust its opening according to instructions from controller 2, achieving controlled deflation of the airbag 4 at a set deflation rate. Controller 2 controls the valve opening based on the deflation rate (e.g., 2 to 3 mmHg per second). During deflation, the pressure sensor feeds real-time pressure data of the airbag 4 back to controller 2. Controller 2 compares the measured pressure value with the target pressure value corresponding to the current moment and determines whether the valve opening needs to be adjusted based on the difference between the two. Specifically, the judgment result can be determined by comparing the difference with a preset difference range. If adjustment is required and the current pressure of the airbag 4 is greater than the target pressure, controller 2 adjusts the valve opening. For example, the pulse width of the drive signal (e.g., PWM signal) can be shortened to reduce the deflation rate of the airbag 4; conversely, it can be increased to accelerate deflation. By adjusting the duration or frequency of the drive signal based on the feedback, the valve opening is adjusted to maintain the deflation rate of the airbag 4 within the set range, ensuring accuracy and comfort during the deflation process.

[0029] In some implementations of this embodiment, the blood pressure data of the subject is obtained based on the real-time pressure value of the airbag 4 in the deflated state, including: obtaining audio data corresponding to the artery of the subject to be measured uploaded by the acoustic sensor; determining the detection moments corresponding to the first audio data and the last audio data respectively, to obtain the first detection moment and the second detection moment; obtaining the real-time pressure values ​​of the airbag 4 in the deflated state corresponding to the first detection moment and the second detection moment respectively, to obtain the systolic pressure and diastolic pressure of the subject to be measured.

[0030] Specifically, as the airbag 4 enters the deflated state, a sensor (e.g., a pressure sensor) can be used to monitor pressure changes in the airbag 4 in real time. The systolic and diastolic pressures of the subject can be determined by detecting Korotkoff sounds, thereby obtaining the subject's blood pressure data. When using Korotkoff sounds to determine systolic and diastolic pressures, the deflation rate of the airbag 4 can be set at 2 to 3 mmHg per second to effectively capture changes in the sounds.

[0031] This blood pressure determination method works as follows: When the airbag 4 is inflated to a sufficiently high pressure (exceeding the subject's systolic pressure), blood flow is blocked, making no sound audible via the acoustic sensor. As the pressure in the airbag 4 is slowly released, blood flow resumes when the pressure drops to just below the systolic pressure, and the vibrations of blood against the arterial wall are detected by the acoustic sensor. This produces the "first" Korotkoff sound, the moment of its appearance corresponding to the systolic pressure measurement. As the pressure in the airbag 4 further decreases, the characteristics and frequency of the Korotkoff sound change. When the pressure in the airbag 4 drops to the diastolic pressure, blood flow stabilizes and the Korotkoff sound disappears. This is called the "last" or "fifth" Korotkoff sound, and the moment of its appearance corresponds to the diastolic pressure measurement. The controller 2 processes the sounds captured by the acoustic sensor to automatically identify the onset and disappearance of the Korotkoff sounds. The systolic and diastolic pressures are then calculated based on the detected audio signal times and the corresponding airbag 4 pressure. The Korotkoff sound measurement method offers a narrow margin of error, effectively ensuring the accuracy and reliability of the measurement results.

[0032] In some implementations of this embodiment, blood pressure data of the subject is obtained based on the real-time pressure value of the airbag 4 in the deflated state, including: obtaining pressure oscillation data corresponding to each real-time pressure value of the airbag 4 in the deflated state; obtaining the pressure value corresponding to the maximum oscillation value to obtain the mean arterial pressure; and calculating the systolic and diastolic pressures of the subject based on the correlation between the mean arterial pressure, the pressure oscillation data and the real-time pressure value.

[0033] Specifically, when the airbag 4 enters the deflated state, the pressure changes of the airbag 4 can be monitored in real time by a sensor that detects pressure data (such as a pressure sensor), and the systolic and diastolic pressures of the subject to be measured can be calculated by monitoring the tiny oscillations of the pressure to obtain the blood pressure data of the subject to be measured.

[0034] The principle of this blood pressure determination method is as follows: Air is inflated into the balloon 4 via an air pump 3, causing it to gradually expand until the pressure within the balloon 4 exceeds the expected systolic pressure, temporarily blocking arterial blood flow. At this point, the pressure within the balloon 4 may be higher than the arterial blood pressure, completely blocking blood flow. As the pressure within the balloon 4 is gradually reduced, blood flow begins to re-enter the artery. As the pressure within the balloon 4 decreases, the impact of blood flowing through the artery generates pressure fluctuations (oscillations). These dynamic changes in blood flow affect the fluctuations in intravascular pressure, producing oscillations of varying frequencies and amplitudes. A pressure sensor monitors the pressure changes within the balloon 4 in real time, recording the tiny oscillations at different pressures. The recorded pressure oscillation data can be displayed as a waveform. Within the oscillation waveform, the balloon 4 pressure corresponding to the maximum oscillation amplitude is determined as the mean arterial pressure (MAP). MAP is an important indicator that reflects the average blood perfusion in the subject. Based on the correlation between the oscillation amplitude, the balloon 4 pressure, and the MAP, the controller 2 uses a pre-set algorithm to estimate the systolic and diastolic blood pressures. The algorithm is based on a statistical model and previous empirical data. Systolic pressure corresponds to the pressure in the airbag 4 at the moment of the first oscillation (when blood flow begins to recover), while diastolic pressure corresponds to the pressure in the airbag 4 at the moment the oscillation disappears.

[0035] Furthermore, before determining blood pressure data based on the pressure data collected by the pressure sensor, the acquired data can be processed, such as by handling missing values. This involves checking for missing values ​​in the pressure data set and deciding how to handle these missing values ​​based on the circumstances. Interpolation, deletion of records with missing values, or other methods can be employed. Abnormal data can also be identified using the standard deviation method, and pressure data can be deduplicated to ensure data accuracy, completeness, and validity. Furthermore, when multiple blood pressure measurement systems are configured in the smart glasses 1, the pressure data can be preprocessed by combining data from two measurement systems.

[0036] Based on the technical solution of the above-mentioned embodiment of the present application, a blood pressure measurement system including a controller, an air pressure pump and an air bag is integrated into the smart glasses, and there is no need to add an additional air bag. When performing a blood pressure test, the air bag is inflated by controlling the air pressure pump. When the pressure value of the air bag reaches a preset pressure value, the air bag is controlled to be exhausted. By obtaining the pressure value in the exhausted state of the air bag, the blood pressure data of the subject can be detected. In this way, blood pressure measurement can be achieved conveniently and efficiently, which improves the portability and wearing comfort of blood pressure measurement and ensures the high accuracy of the measurement results. Users only need to wear a pair of glasses to complete blood pressure measurement, which is suitable for a variety of life scenarios and effectively improves user experience.

[0037] This application also provides a blood pressure measurement method, which is applied to the above-mentioned smart glasses, such as Figure 2The method in FIG. 1 is a basic flow chart of a blood pressure measurement method provided in an embodiment of the present application, and the blood pressure measurement method includes:

[0038] Step 201: When a blood pressure measurement instruction is received, the air pressure pump is controlled to enter a working state;

[0039] Step 202: When the airbag pressure reaches a preset pressure value, the air pressure pump is controlled to enter a cut-off state, and the airbag is controlled to enter a deflation state;

[0040] Step 203: Obtaining blood pressure data of the subject according to the real-time pressure value of the airbag in the deflated state;

[0041] For details, see Figure 3 The flow chart of the blood pressure measurement method shown in the figure shows that after the subject wears the smart glasses integrated with the blood pressure measurement system, the controller starts to control the air pressure pump according to the blood pressure measurement instruction. The blood pressure measurement instruction received by the controller can be a user-input start-up instruction or a command generated by automatic detection. The user-input instruction can be generated directly through the corresponding function button set on the smart glasses or a command issued by a terminal, which is transmitted to the controller in the blood pressure measurement system via wireless communication. After receiving the blood pressure measurement instruction, the controller controls the air pressure pump to inflate the airbag, increasing the pressure inside the airbag until the pressure reaches a preset value. When the pressure reaches the preset value, the airbag expands and compresses the artery, temporarily blocking blood flow. The air pressure pump is then controlled to stop and the airbag enters the deflated state. During this period, the airbag pressure change can be detected, for example, using a sensor that detects pressure data (such as a pressure sensor). The blood pressure data of the subject is then analyzed based on the airbag pressure value, achieving fast and convenient blood pressure measurement.

[0042] In some implementations of this embodiment, blood pressure data of the subject is obtained based on the real-time pressure value of the airbag in the deflated state, including: obtaining audio data corresponding to the artery of the subject to be measured uploaded by the acoustic sensor; the audio data is generated by the blood flow of the subject to be measured entering the artery; determining the detection moments corresponding to the first audio data and the last audio data respectively, to obtain the first detection moment and the second detection moment; obtaining the real-time pressure values ​​of the airbag in the deflated state corresponding to the first detection moment and the second detection moment respectively, to obtain the systolic pressure and diastolic pressure of the subject to be measured.

[0043] Specifically, during the deflation phase of the airbag, a sensor (such as a pressure sensor) can be used to monitor airbag pressure changes in real time. By detecting Korotkoff sounds, the subject's systolic and diastolic blood pressure can be determined, thereby obtaining the subject's blood pressure data. When using Korotkoff sounds to determine systolic and diastolic blood pressure, the airbag deflation rate can be set at 2 to 3 mmHg per second to effectively capture changes in the sounds.

[0044] This blood pressure determination method works as follows: When the balloon is inflated to a sufficiently high pressure (exceeding the subject's systolic pressure), blood flow is blocked, making no sound audible via the acoustic sensor. As the balloon pressure is slowly released, blood flow resumes when the balloon pressure drops to just below the systolic pressure, and the vibrations of blood against the arterial wall are detected by the acoustic sensor. This produces the "first" Korotkoff sound, the moment of its appearance corresponding to the systolic pressure measurement. As the balloon pressure decreases further, the characteristics and frequency of the Korotkoff sound change. When the balloon pressure drops to the diastolic pressure, blood flow stabilizes and the Korotkoff sound disappears. This is called the "last" or "fifth" Korotkoff sound, and the moment of its appearance corresponds to the diastolic pressure measurement. A controller processes the sounds captured by the acoustic sensor to automatically identify the onset and disappearance of the Korotkoff sounds. The systolic and diastolic pressures are then calculated based on the detected audio signal times and the corresponding balloon pressures. The Korotkoff sound measurement method offers a narrow margin of error, effectively ensuring accurate and reliable measurement results.

[0045] In other implementations of this embodiment, blood pressure data of the subject is obtained based on the real-time pressure value of the airbag in the deflated state, including: obtaining pressure oscillation data corresponding to each real-time pressure value of the airbag in the deflated state; obtaining the pressure value corresponding to the maximum oscillation value to obtain the mean arterial pressure; and calculating the systolic and diastolic pressures of the subject based on the correlation between the mean arterial pressure, the pressure oscillation data and the real-time pressure value.

[0046] Specifically, when the airbag enters the deflated state, the airbag pressure changes can be monitored in real time by using a sensor that detects pressure data (such as a pressure sensor), and the systolic and diastolic pressures of the subject to be measured can be calculated by monitoring the tiny oscillations of pressure to obtain the blood pressure data of the subject to be measured.

[0047] This blood pressure determination method works as follows: A pneumatic pump inflates the balloon, gradually expanding it until the pressure inside the balloon exceeds the expected systolic pressure, temporarily blocking arterial blood flow. At this point, the pressure inside the balloon may exceed arterial blood pressure, completely blocking blood flow. As the pressure inside the balloon is gradually reduced, blood flow begins to re-enter the artery. As the balloon pressure decreases, the impact of blood flowing through the artery generates pressure fluctuations (oscillations). These dynamic changes in blood flow affect the fluctuations in intravascular pressure, producing oscillations of varying frequencies and amplitudes. A pressure sensor monitors pressure changes inside the balloon in real time, recording tiny oscillations at different pressures. The recorded pressure oscillation data can be displayed as a waveform. Within the oscillation waveform, the balloon pressure corresponding to the maximum oscillation amplitude is determined as the mean arterial pressure (MAP). Based on the relationship between oscillation amplitude and balloon pressure, the controller estimates systolic and diastolic pressures using a pre-set algorithm. This algorithm is based on a statistical model and prior empirical data. Systolic pressure corresponds to the balloon pressure at the moment of the first oscillation (when blood flow begins to resume). The diastolic pressure corresponds to the cuff pressure at the moment when the oscillation disappears.

[0048] In addition, after obtaining blood pressure measurement data, a health monitoring report is generated and transmitted to user terminals such as smartphones or the cloud through wireless communication technologies such as Wi-Fi, Bluetooth, and NFC, allowing users to view and analyze health data at any time.

[0049] Based on the above technical solutions of the embodiments of the present application, by integrating the blood pressure measurement system into the smart glasses, when performing a blood pressure test, the air bag is inflated by controlling the air pressure pump. When the pressure value of the air bag reaches the preset pressure value, the air bag is controlled to be exhausted. By obtaining the pressure value in the exhausted state of the air bag, the blood pressure data of the subject can be detected, thereby realizing blood pressure measurement conveniently and efficiently. The measurement is based on the Korotkoff sound method and the oscillation method, ensuring the high accuracy of the measurement results. The measurement data is synchronized to the terminal or the cloud through wireless communication. The user can view all blood pressure data on one device, reducing the complexity of operation and improving the user experience.
