Description

Technical Field

[0001] The present application relates to the field of smart terminal technology, and in particular to a blood pressure monitoring method, apparatus, and wearable device. Background Art

[0002] The prevalence of cardiovascular disease (CVD) in China continues to rise. Currently, 290 million people in my country suffer from the disease, and approximately 3.5 million people die from CVD each year. CVD leads the mortality rate, surpassing cancer and other diseases. Among every 100,000 rural and urban residents, 143.72 and 136.21 people die from heart disease, respectively, posing a serious threat to the health of the Chinese people. Hypertension is the leading risk factor for cardiovascular and cerebrovascular disease, and approximately 270 million people in China suffer from hypertension. The China Hypertension Survey (CHS) conducted between 2012 and 2015 showed that the prevalence of hypertension among adults in China was 27.9%, with an increasing trend among residents aged 15 years and older. However, China's current hypertension awareness rate is approximately 51.5%, medication use rate is approximately 46.1%, and control rate is approximately 16.9%, all significantly lower than the United States' rates of 86.2%, 73%, and 61%, respectively.

[0003] Continuous blood pressure monitoring is a major innovation in the development of hypertension diagnostic technology. It can measure a person's blood pressure in daily life, during light or moderate physical activity, and even during sleep. Continuous blood pressure monitoring eliminates random measurements, reduces misdiagnosis rates, identifies latent nocturnal hypertension, identifies white-coat hypertension, measures blood pressure rhythms, and guides medication treatment.

[0004] Current blood pressure measurement methods, such as auscultation and oscillometric methods, require manual or automatic inflation and deflation of the cuff to assist in measurement. This can cause discomfort to the user and can only measure blood pressure once per period, preventing continuous measurement. Non-invasive cuffless blood pressure measurement methods (such as the pulse wave characteristic parameter method and pulse wave velocity blood pressure measurement method) can achieve continuous blood pressure monitoring. However, since blood pressure measurement models established for different subjects are highly susceptible to individual differences, blood pressure calibration is usually performed with the aid of a blood pressure cuff to minimize the impact of individual differences on blood pressure prediction results. The continuous changes in blood pressure are monitored based on the calibration value.

[0005] However, the existing method of calibrating blood pressure of continuous blood pressure monitoring equipment with the help of a blood pressure cuff has a poor calibration effect, and the accuracy of blood pressure measurement after calibration needs to be improved. Summary of the Invention

[0006] In view of this, a blood pressure monitoring method, apparatus and wearable device are proposed.

[0007] In a first aspect, an embodiment of the present application provides a blood pressure monitoring method, the method comprising: in response to a first operation, the electronic device enters a calibration mode; displays a first graphical user interface, the first graphical user interface being used to prompt a user to perform a first action; measures a first blood pressure value, and collects first physiological indicator information; displays a second graphical user interface, the second graphical user interface being used to prompt a user to perform a second action; measures a second blood pressure value, and collects second physiological indicator information; in response to a second operation, the electronic device enters a measurement mode; collects third physiological indicator information; and determines a third blood pressure value corresponding to the third physiological indicator information based on the first blood pressure value, the second blood pressure value, the first physiological indicator information, and the second physiological indicator information.

[0008] Based on the above technical solution, during the calibration phase, multiple graphical user interfaces (including a first graphical user interface and a second graphical user interface) are displayed to prompt the user to perform different actions (including a first action and a second action), thereby causing changes in the user's blood pressure influencing factors such as heart rate, stroke volume, and total peripheral resistance. The blood pressure values ​​(including a first blood pressure value and a second blood pressure value) of the user when performing different actions are measured respectively, and physiological indicator information (including a first physiological indicator information and a second physiological indicator information) is collected to fully capture the changes in the user's blood pressure influencing factors and achieve blood pressure calibration in multiple calibration scenarios; during the measurement phase, based on the multiple blood pressure values ​​and multiple physiological indicator information obtained during the calibration phase, the blood pressure value (i.e., the third blood pressure value) corresponding to the collected physiological indicator information (i.e., the third physiological indicator information) is determined. The accuracy of this blood pressure value is higher, thereby achieving accurate measurement of the user's blood pressure.

[0009] According to the first aspect, in a first possible implementation of the first aspect, after the electronic device enters the calibration mode in response to the first operation, it also includes: displaying a third graphical user interface, wherein the third graphical user interface displays options for multiple calibration scenarios; and displaying the first graphical user interface in response to the user's selection operation of the calibration scenario.

[0010] Based on the above technical solution, users can choose the most suitable and matching calibration scenario according to their daily activities to complete calibration, which can make calibration more personalized and targeted, effectively reduce calibration time, and improve user experience.

[0011] According to a first possible implementation manner of the first aspect, in a second possible implementation manner of the first aspect, the calibration scenario corresponds to one or more of a calibration scenario of the user's physical state and a calibration scenario of the state of the user's environment.

[0012] Based on the above technical solution, in different calibration scenarios, the user's physical condition, the state of the user's environment, etc. are different. Accordingly, the user's blood pressure influencing factors such as heart rate, cardiac volume, total peripheral resistance, etc. change. The user's blood pressure influencing factors are induced to change by different user physical conditions or different states of the user's environment, thereby fully capturing the changes in the user's blood pressure influencing factors and realizing blood pressure calibration under different user physical conditions or different states of the user's environment.

[0013] According to the second possible implementation manner of the first aspect, in the third possible implementation manner of the first aspect, the calibration scenes corresponding to the user's physical state include one or more of a sitting scene, a lying scene, a standing scene, a mental activity scene, a relaxation / rest scene, an anaerobic exercise scene, and an aerobic exercise scene; the calibration scenes corresponding to the state of the user's environment include one or more of a cold scene and a stuffy scene.

[0014] Based on the above technical solution, in different scenarios, the user's blood pressure influencing factors such as heart rate, stroke volume, total peripheral resistance, etc. change. The multiple calibration scenarios provided can more comprehensively cover the changes in the user's blood pressure influencing factors, thereby realizing blood pressure calibration in different scenarios and improving the accuracy of blood pressure measurement of the calibrated wearable device.

[0015] According to the first aspect or multiple possible implementations of the first aspect, in a fourth possible implementation of the first aspect, after displaying the first graphical user interface, the method further includes: displaying a fourth graphical user interface, wherein the fourth graphical user interface displays timing information.

[0016] Based on the above technical solution, timing information is displayed through the fourth graphical user interface to prompt the user of the time when the first action has been performed, or the time when the first action is still required. The user can complete the indicated exercise according to the prompts of the graphical user interface, thereby completing the blood pressure measurement in the corresponding calibration scenario, which is simple and convenient and improves the user experience.

[0018] Based on the above technical solution, the first moment can represent the time point when the drug concentration in the user's body is the highest, and the second moment can represent the time point when the drug concentration in the user's body is the lowest. In this way, the fifth graphical user interface is displayed when the user's drug concentration is the highest and the drug concentration is the lowest, prompting the user to calibrate the blood pressure. This fully considers the impact of changes in drug concentration on the user's blood pressure, improves the accuracy of blood pressure calibration, and thus makes the blood pressure value measured by the calibrated wearable device more accurate.

When the difference between the two is greater than the first threshold, the fifth graphical user interface is displayed to remind the user to perform the first operation, that is, reminding the user to calibrate the blood pressure of the wearable device, thereby improving the accuracy of blood pressure measurement by the calibrated wearable device.

[0022] Based on the above technical solution, one or several target blood pressure values ​​that are most similar to the current measurement scenario obtained in the calibration phase are selected, and these target blood pressure values ​​are weighted and summed to predict the third blood pressure value currently measured. The weight of each target blood pressure value is positively correlated with the similarity between the corresponding target physiological indicator information and the third physiological indicator information; that is, the higher the similarity, the greater the weight of the corresponding target blood pressure value, thereby increasing the blood pressure measurement range and improving the accuracy of blood pressure measurement.

[0097] Various exemplary embodiments, features, and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

[0098] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0099] In addition, numerous specific details are provided in the following detailed description to better illustrate the present application. Those skilled in the art will appreciate that the present application can be practiced without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0100] Hypertension is the most common chronic non-communicable disease and carries the heaviest global disease burden. Hypertension is associated with a range of clinical conditions and adverse outcomes, and has become a major public health issue. The mechanisms of cardiovascular and cerebrovascular events associated with hypertension vary among ethnic groups. Given the world's large population and the increasing aging of the population, the rational diagnosis and treatment of hypertension is crucial. Continuous blood pressure monitoring, represented by ambulatory blood pressure monitoring (ABPM), is an important out-of-office blood pressure measurement method and plays a central role in hypertension monitoring and management. ABPM plays an important role in detecting hidden hypertension, abnormal blood pressure variability, and abnormal blood pressure rhythm.

[0101] Mobile medical technology, exemplified by smart wearable devices, has recently experienced rapid growth, with wearable-based blood pressure measurement technology being of particular importance. Due to differences in measurement location and principle, blood pressure measurements using smart wearables are generally less accurate than those based on auscultation and oscillometric methods. Continuous blood pressure monitoring using smart wearables requires calibration to improve accuracy.

[0102] The following is a brief introduction to some related technologies for calibrating blood pressure on smart wearable devices.

[0103] Some related technologies acquire multiple sets of user data in a specific scenario, each including pulse wave transit time and blood pressure values. Based on these multiple sets of data, a set of parameters is determined for measuring blood pressure using a sphygmomanometer. In this example, the scenario is simple, the factors influencing blood pressure vary only slightly, and there is a lack of a relatively accurate blood pressure value as a baseline. Consequently, the effectiveness of blood pressure calibration and tracking is poor.

[0104] In other related technologies, the blood pressure cuff can be placed on the upper arm and the watch to be calibrated can be worn on the wrist of the other arm. Place the mobile phone on the table for easy access. On the mobile phone, open the relevant application and follow the on-screen instructions to do the following: Start blood pressure measurement on the cuff-based blood pressure monitor. The measurement on the watch to be calibrated will start automatically. Enter the cuff-based blood pressure monitoring reading in the mobile phone blood pressure monitoring application. Repeat the above steps twice (a total of three measurements) to complete the calibration of the watch to be calibrated. In this related technology, calibration is only performed in one scene of sitting still. The blood pressure value measured during use fluctuates slightly around the calibration value, and it is impossible to track large changes in blood pressure. This is because there is only a single scene of sitting still during the calibration process, which cannot induce the state of the user's blood pressure influencing factors to change. When the user actually measures blood pressure, the state of the blood pressure influencing factors is diverse, which leads to inaccurate blood pressure measurement values ​​during blood pressure measurement and inability to track changes in blood pressure.

[0105] In order to solve the technical problem of poor blood pressure calibration effect mentioned above, an embodiment of the present application provides a blood pressure monitoring method. The blood pressure monitoring method of the embodiment of the present application can be executed by a blood pressure monitoring device, and prompts the user to complete physical activities that meet multiple calibration scenarios through prompt information; after the user completes physical activities in different calibration scenarios, the user's blood pressure influencing factors such as heart rate, stroke volume, total peripheral resistance, etc. change. In the blood pressure calibration stage, the user's calibrated blood pressure value and corresponding physiological signals in each calibration scenario are obtained, and the changes in the user's blood pressure influencing factors are fully captured to achieve blood pressure calibration in multiple calibration scenarios; in the blood pressure measurement stage, the measured blood pressure value of the user is determined based on the collected physiological signals, as well as the calibrated blood pressure values ​​and corresponding physiological signals in each of the above-mentioned calibration scenarios. The blood pressure value has higher accuracy, thereby achieving accurate measurement of the user's blood pressure.

[0106] Among them, the blood pressure monitoring device can be a device that has the function of measuring the user's blood pressure and can improve the accuracy of blood pressure measurement through calibration. The blood pressure monitoring device may include an electrocardiogram (ECG) sensor, a photoplethysmography (PPG) sensor, a pressure sensor, a ballistocardiography (BCG) sensor, a seismocardiography (SCG) sensor, an impedance plethysmography (IPG) sensor, and other sensors that can collect the user's physiological signals. These sensors measure the user's PPG, ECG, IPG, SCG, BCG, heart sounds and other physiological signals, determine the corresponding physiological indicator information, and thus obtain the user's blood pressure value.

[0107] For example, the blood pressure monitoring device can be a smart wearable device with a blood pressure monitoring function. The wearable device can be a device worn on the arm or wrist, such as a smart wearable watch; it can also be a device worn on the chest or palm, such as a smart necklace; it can also be a device worn on the head, such as a smart headset; this application does not limit the specific form of the smart wearable device. For example, the blood pressure monitoring device can be a professional device in a hospital with a blood pressure monitoring function, such as a 24-hour ambulatory blood pressure monitor; for example, the blood pressure monitoring device can also be a smart body fat scale, blood pressure meter, or other device with a blood pressure monitoring function.

[0108] In the embodiment of the present application, the blood pressure monitoring method provided in the present application is described by taking a smart wearable watch as an example of a blood pressure monitoring device.

[0109] Figure 1 A schematic diagram of an application scenario according to an embodiment of the present application is shown; Figure 1 As shown, when calibrating blood pressure, the user wears the smart wearable watch 101 on the left hand or right hand (the figure shows that the smart wearable watch 101 is worn on the right wrist). In order to achieve better blood pressure measurement results, the user can put the strap of the smart wearable watch 101 close to the wrist.

[0110] In some examples, the smart wearable watch 101 may include: an airbag (such as a micropump airbag), a pressure sensor and a PPG sensor, or may also include an ECG sensor; wherein the airbag and the pressure sensor work together to measure the user's blood pressure value by the oscillometric method, and the blood pressure value is used as the calibration blood pressure value. The measurement process may include: automatically inflating the airbag by pressurizing it with a micropump, stopping pressurization after a certain period of inflation, and starting to deflate. When the air pressure drops to a certain level, blood can flow through the blood vessels with a certain oscillation wave. The oscillation wave propagates to the pressure sensor. The pressure sensor can detect the pressure and fluctuation in the airbag in real time, and then calculate the user's blood pressure value based on the pressure and fluctuation based on the oscillometric principle. The blood pressure value is the calibration blood pressure value.

[0111] The PPG sensor is used to collect PPG signals. The collection process includes: the light-emitting diode of the PPG sensor emits a photoelectric signal to the user's skin, and the pulse wave is collected by the photosensitive diode of the PPG sensor to generate a PPG signal. The ECG sensor can be used to collect ECG signals. In related technologies, the blood pressure value can be obtained by measuring the pulse wave characteristic parameters based on the correspondence between the characteristic values ​​of the preset characteristics of the PPG signal and the blood pressure value. This measurement principle is based on the pre-established correspondence between different characteristic values ​​of the preset characteristics of the PPG signal and the blood pressure value. After calculating the characteristic value of the preset characteristic of the actually measured PPG signal, the blood pressure value corresponding to the characteristic value is determined based on the correspondence, which is the user's blood pressure value. Alternatively, the PPG sensor and ECG sensor can be used in conjunction to measure the user's blood pressure using the pulse wave velocity blood pressure measurement method; this measurement principle is based on the positive correlation between the pulse wave velocity (PWV), the rate at which the pulse propagates along the artery, and arterial blood pressure; commonly used PWV measurement methods may include calculating the pulse wave transit time (PTT), which is the time required for the pulse wave to be transmitted from the heart to a certain point on the artery, specifically including: synchronously collecting ECG signals and PPG signals, identifying the maximum value points of the R wave of the ECG signal and the PPG signal, and obtaining the delay time PTT; through a preset mathematical model relationship between PTT and blood pressure (for example, a linear function relationship between PTT and blood pressure), the systolic and diastolic blood pressure values ​​are finally obtained.

[0112] It should be noted that the above-mentioned pulse wave characteristic parameter method and pulse wave velocity blood pressure measurement method are only examples. In related technologies, the user's blood pressure value can also be obtained through other non-invasive cuffless blood pressure measurement methods. For example, the pulse wave velocity blood pressure measurement method can also be combined with the pulse wave characteristic parameter method to obtain the blood pressure value.

[0113] In this scenario, in order to obtain a blood pressure value with higher accuracy than the blood pressure value based on the PPG signal or the combination of the PPG signal and the ECG signal, the smart wearable watch can obtain a calibrated blood pressure value through the airbag and pressure sensor, and then combine the calibrated blood pressure value with the physiological signal obtained by the PPG sensor (or PPG sensor, ECG sensor, etc.) to obtain a more accurate blood pressure value. Blood pressure calibration can be completed without relying on other equipment, which is convenient and quick.

[0114] Figure 2 FIG. 1 shows another application scenario diagram according to an embodiment of the present application; FIG. Figure 2 As shown, when calibrating blood pressure, the user wears the smart wearable watch 101 and the blood pressure monitor 102 on the left arm and the right arm respectively (the figure shows that the smart wearable watch 101 is worn on the right wrist and the blood pressure monitor 102 is worn on the left arm). The smart wearable watch 101 and the blood pressure monitor 102 can also be worn on the left arm or the right arm (not shown in the figure). In order to achieve a better blood pressure measurement effect, the user can put the strap of the smart wearable watch 101 close to the wrist and the cuff of the blood pressure monitor 102 close to the arm. For example, the smart wearable watch 101 and the blood pressure monitor 102 can be connected via a wired or wireless method (such as Bluetooth, WiFi, etc.).

[0115] The blood pressure monitor 102 may be a medically certified blood pressure monitor, and the blood pressure monitor 102 may measure the user's blood pressure value by an oscillometric method.

[0116] In some examples, the smart wearable watch 101 may include a PPG sensor or an ECG sensor. The working principles of the PPG sensor and the ECG sensor can be found above.

[0117] In this scenario, in order to obtain a blood pressure value with higher accuracy than the blood pressure value based on the PPG signal or the combination of the PPG signal and the ECG signal, the smart wearable watch can measure and calibrate the blood pressure value through the blood pressure monitor, and then combine the calibrated blood pressure value with the physiological signal obtained by the PPG sensor (or PPG sensor, ECG sensor, etc.) to obtain a higher-precision blood pressure value, thereby further improving the calibration accuracy.

[0118] It should be noted that the above-mentioned application scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. Ordinary technicians in this field can know that the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems when other similar or new application scenarios emerge.

[0119] The following combination Figure 1The application scenario shown in the figure illustrates the blood pressure monitoring method provided by this application.

[0120] Figure 3 A flow chart of a blood pressure monitoring method according to an embodiment of the present application is shown. Figure 3 As shown, the method may include the following steps:

[0121] Step 301: The smart wearable watch enters a calibration mode in response to a user's instruction.

[0122] In this step, if you need to Figure 1 When the smart wearable watch 101 performs blood pressure calibration, the user can trigger an instruction to enter the calibration mode, and the smart wearable watch enters the calibration mode in response to the instruction; exemplarily, the user can trigger the instruction to enter the calibration mode by clicking a virtual button of the calibration mode on the display screen of the smart wearable watch; exemplarily, the user can also trigger the instruction to enter the calibration mode by pressing a physical button for entering the calibration mode set on the smart wearable watch; exemplarily, the user can also trigger the instruction to enter the calibration mode by voice command; exemplarily, the user can also trigger the instruction to enter the calibration mode by a shortcut gesture; in actual application, the user can also trigger the instruction to enter the calibration mode by other means, and the embodiments of the present application are not limited to this.

[0123] For example, Figure 4 FIG. 1 is a schematic diagram showing a smart wearable watch entering a calibration mode according to an embodiment of the present application. Figure 4 As shown in (a), the user can click the icon of the "blood pressure" application on the smart wearable watch to trigger the smart wearable watch 101 to execute the application, such as Figure 4 As shown in (b), a virtual button 401 for calibration mode and a virtual button 402 for measurement mode are displayed on the display screen of the smart wearable watch 101; the user can trigger an instruction to enter the calibration mode by clicking the virtual button 401 for calibration mode, and the smart wearable watch 101 responds to the instruction and enters the calibration mode.

[0124] Step 302: The smart wearable watch measures the user's calibrated blood pressure value in each of the different calibration scenarios and collects the user's physiological signals.

[0125] In this step, the smart wearable watch collects physiological signals from the user under different preset calibration scenarios. These physiological signals may include pulse wave signals and electrocardiogram (ECG) signals. ECG signals are generated by the user's heartbeat, such as ECG signals; pulse wave signals are generated by the interaction of blood flowing within blood vessels, such as PPG signals. Simultaneously, the smart wearable watch's airbag and pressure sensor work together to measure the user's blood pressure using an oscillometric method, which serves as the calibration blood pressure value.

[0126] In one possible implementation, the smart wearable watch measures the user's calibrated blood pressure value and collects the user's physiological signals in each calibration scenario, which may include: the smart wearable watch can measure the calibrated blood pressure value in the calibration scenario by an oscillometric method, and collect the user's physiological signals in the scenario; wherein, the time for measuring the calibrated blood pressure value in the calibration scenario can be before the time of collecting the user's physiological signals in the scenario, or after the time of collecting the user's physiological signals in the scenario. For example, after the calibrated blood pressure value in the scenario is obtained by the oscillometric method, the user's physiological signals in the calibration scenario can be collected at an interval of a certain time, so as to avoid the influence of air pressure changes on physiological signals; for example, the airbag and pressure sensor of the smart wearable watch work together to obtain the calibrated blood pressure value in the calibration scenario, and after an interval of 30S, the PPG sensor of the smart wearable watch starts working to collect the user's PPG signal, or the PPG sensor and ECG sensor of the smart wearable watch start working to collect the user's PPG signal and ECG signal.

[0127] Taking into account the different environments such as body position, posture, exercise, diet, medication, time of day, season, and environment, all of which will lead to changes in blood pressure. Changes in blood pressure are achieved by changing factors such as cardiac output (CO) and total peripheral resistance (TPR). CO is affected by heart rate (HR) and stroke volume, while TPR is affected by arteriolar radius (AR) and blood viscosity. Heart rate, stroke volume, arteriolar diameter, and blood viscosity can also be affected by other factors. Therefore, in an embodiment of the present application, the calibration scenario can be a preset scenario. In different scenarios, the user's physical state or the state of the user's environment is different. In this way, by designing scenarios to induce changes in the user's physical state or the state of the user's environment, blood pressure influencing factors such as heart rate, cardiac volume, total peripheral resistance, etc. change in different physical states or the state of the user's environment. Blood pressure calibration is performed under various physical states or the state of the user's environment, and the user's physiological signals and calibrated blood pressure values ​​in different physical states or the state of the user's environment are obtained, so as to fully capture the changes in the user's blood pressure influencing factors, and then the calibrated device can be used to achieve accurate tracking of the user's blood pressure.

[0128] For example, Table 1 shows several preset calibration scenes; as shown in Table 1, the calibration scenes may include: sitting scene, lying scene, standing scene, mental activity scene, relaxation / rest scene, anaerobic exercise scene, aerobic exercise scene, cold scene, stuffy scene, etc.

[0129] Among them, the sitting still scene, lying still scene, and standing still scene are scenes in a quiet state. These scenes represent the changes in the user's physical state in different postures. For example, the sitting still scene may include the user's sitting still activities, representing the physical state in the sitting posture; the lying still scene may include the user's lying still activities, representing the physical state in the lying posture; and the standing scene may include the user's standing still activities, representing the physical state in the standing posture.

[0130] Among them, mental activity scenes and relaxation / rest scenes are scenes under neural activity. These scenes represent the changes in the user's physical state when the sympathetic and / or parasympathetic nerves are excited to different degrees. For example, mental activity scenes may include: doing math problems, answering questions, etc., which represent the physical state of sympathetic nerve excitement, stimulating an increase in heart rate and stroke volume, constricting veins to increase venous return, constricting arteries to increase peripheral resistance, and raising blood pressure; relaxation / rest scenes may include activities such as the Vasalva test, which represent the physical state of parasympathetic nerve excitement, stimulating a decrease in heart rate and blood pressure.

[0131] Among them, anaerobic exercise scenes and aerobic exercise scenes are scenes during exercise, which represent the changes in the user's physical state during aerobic and / or anaerobic exercise. For example, anaerobic exercise scenes can include activities such as horse stance, which represent physical conditions that increase heart rate, increase cardiac output, increase peripheral resistance, and rapidly increase blood pressure. Aerobic exercise scenes can include activities such as cycling and step tests, which represent physical conditions that increase heart rate, increase cardiac output, reduce peripheral resistance, and increase blood pressure.

[0132] Cold and hot scenes are temperature-related scenes that represent changes in the user's environment. For example, cold scenes can include activities such as cold water stimulation, which causes peripheral vasoconstriction, increased peripheral resistance, and increased blood pressure; hot scenes can include activities such as hot water stimulation, which causes peripheral vasodilation, reduced peripheral resistance, and lowered blood pressure.

[0133] Table 1 - Calibration scenario table

[0134]

[0135] The following uses the sitting still scene, lying still scene, mental activity scene, relaxation / rest scene, and anaerobic exercise scene as examples to illustrate the process of users completing blood pressure calibration through a smart wearable watch in different calibration scenarios.

[0136] Figure 5 A schematic diagram of blood pressure calibration under multiple calibration scenarios according to an embodiment of the present application is shown; the smart wearable watch provides prompt information for sitting still scenarios, lying still scenarios, mental activity scenarios, and relaxation / rest scenarios, thereby prompting the user to complete physical activities that conform to each calibration scenario; after starting blood pressure calibration under a calibration scenario, the physical activities for the calibration scenario can be prompted on the display screen of the smart wearable watch, thereby prompting the user to complete the physical activities that the user needs to complete in the calibration scenario. In addition, the smart wearable watch can also remind the user of the physical activities to be completed in the form of language broadcasts. The smart wearable watch can also demonstrate and guide the user to physical activities in the form of voice, pictures, videos, etc.; for example, Figure 5As shown in (a1), after starting the blood pressure calibration in the lying-still scenario, the screen displays the words "Please lie still for 1 minute" to remind the user that the user needs to maintain a lying-still posture for 1 minute in this calibration scenario; Figure 5 As shown in (a2), after the blood pressure calibration starts in the sitting meditation scene, the screen displays the words "Please sit quietly for 1 minute" to remind the user to maintain a sitting posture for 1 minute; Figure 5 As shown in (a3), after the blood pressure calibration in the mental activity scenario begins, the display screen may show the user performing mathematical operations according to certain rules for one minute or display quiz questions for the user to answer. For example, the words "Please perform the calculation of subtracting 7 from 500 continuously for one minute" may be displayed to remind the user to perform the calculation of subtracting 7 from 500 continuously (i.e., 500-7=493, 493-7=486...) for one minute; Figure 5 As shown in (a4), after the blood pressure calibration in the relaxation / rest scene begins, the screen displays "Valsaval activity for one minute (please inhale, close your mouth and nose, and exhale forcefully 5 times)", thereby reminding the user to perform the Valsaval activity for one minute, specifically, inhale, close your mouth and nose, and exhale forcefully 5 times within one minute; after prompting the user to complete the physical activities required in the calibration scene, as shown in (a4). Figure 5 As shown in (b), the words "Countdown is about to begin" are displayed on the display screen of the smart wearable watch, thereby reminding the user to prepare for physical activities that conform to the calibration scenario, for example, prepare to maintain a lying posture for 1 minute, prepare to maintain a sitting posture for 1 minute, prepare to perform mathematical operations for 1 minute, and prepare to perform Valsaval activities for 1 minute. In addition, the smart wearable watch can also remind the user in the form of language broadcast that the countdown is about to begin; Figure 5 As shown in (c), the display screen of the smart wearable watch can display the word "countdown", the countdown time, and dynamic patterns such as "hourglass" and "progress bar", so as to remind the user to continue the physical activity that conforms to the calibration scenario, and to remind the user of the time for which the physical activity that conforms to the calibration scenario is required. In addition, the smart wearable watch can also remind the user to continue the physical activity that conforms to the calibration scenario in the form of language broadcast, and to remind the user of the time for which the physical activity that conforms to the calibration scenario is required; Figure 5As shown in (d), after the countdown ends, the words "Blood pressure is being measured, please keep still" are displayed on the display screen of the smart wearable watch to remind the user to keep still. In addition, the smart wearable watch can also remind the user to keep still in the form of language broadcast; for example, in a lying down scene, the user can be reminded to keep lying still, and in a sitting down scene, a mental activity scene, and a relaxation / resting scene, the user can be reminded to keep sitting still; at this time, the airbag and pressure sensor of the smart wearable watch work together to measure the user's blood pressure, and the PPG sensor (or, PPG sensor and ECG sensor) of the smart wearable watch collects the user's physiological signals. Figure 5 As shown in (e), the words "Measurement Completed" are displayed on the display screen of the smart wearable watch, thereby reminding the user that a blood pressure measurement in the calibration scenario is completed. In addition, the smart wearable watch can also remind the user that a blood pressure measurement in the calibration scenario is completed in the form of language broadcast.

[0137] Figure 6 A schematic diagram of blood pressure calibration in an anaerobic exercise scenario according to an embodiment of the present application is shown; the smart wearable watch provides prompt information for the anaerobic exercise scenario, thereby prompting the user to complete physical activities that meet the anaerobic exercise scenario; after starting blood pressure calibration in the anaerobic exercise scenario, the following steps are executed in sequence: Figure 6 (a)-6(c) process, such as Figure 6 As shown in (a), the words "Please do the horse stance to the limit, then sit down and click to start measuring" and a virtual start button are displayed on the display screen of the smart wearable watch, thereby reminding the user that the horse stance needs to be done to the limit in this calibration scenario, and then sit down and click to start measuring. In addition, the smart wearable watch can also remind the user in the form of language broadcast that the horse stance needs to be done to the limit, and then sit down and click to start measuring. The smart wearable watch can also demonstrate and guide the user to do the horse stance to the limit in the form of voice, pictures, videos, etc.; the user clicks the start button on the premise that the horse stance is done to the limit and the user maintains a sitting position, triggering the start blood pressure measurement instruction, and the smart wearable watch responds to the instruction and starts blood pressure measurement, as shown in FIG. Figure 6 As shown in (b), the words "Blood pressure is being measured, please keep still" are displayed on the display screen of the smart wearable watch, thereby reminding the user to keep still. In addition, the smart wearable watch can also remind the user to keep sitting still in the form of language broadcast; at this time, the airbag and pressure sensor of the smart wearable watch work together to measure the user's calibrated blood pressure value, and the PPG sensor (or, PPG sensor and ECG sensor) of the smart wearable watch collects the user's physiological signals. Figure 6 As shown in (c), the words "measurement completed" are displayed on the display screen of the smart wearable watch, thereby reminding the user that the blood pressure measurement in the anaerobic exercise scenario is completed. In addition, the smart wearable watch can also remind the user that a blood pressure measurement in the anaerobic exercise scenario is completed in the form of language broadcast.

[0138] In one possible implementation, the smart wearable watch can measure the user's calibrated blood pressure value and collect the user's physiological signals in each calibration scenario under the standard scenario.

[0139] For example, Figure 7 FIG. 1 is a schematic diagram showing a calibration scenario selection according to an embodiment of the present application; FIG. Figure 7 As shown, the user clicks Figure 7 The virtual button 401 of the calibration mode in (a) triggers the smart wearable watch 101 to enter the calibration mode. Figure 7 In the calibration mode shown in (b), a virtual button 1001 for the standard scene and a virtual button 1002 for the custom scene are displayed on the display screen of the smart wearable watch 101; the user can trigger an instruction to perform blood pressure calibration in the standard scene by clicking the virtual button 1001 for the standard scene, and the smart wearable watch 101 responds to the instruction and executes the blood pressure calibration process under the standard scene.

[0140] The standard scene may include a fixed combination of the above-mentioned multiple preset calibration scenes, and each calibration scene has a fixed execution order. For example, the standard scene may include: a sitting still scene, a lying still scene, a mental activity scene, a relaxation / resting scene, and an anaerobic exercise scene. It should be noted that the type and number of calibration scenes included in the standard scene, as well as the execution order of each calibration scene, can be set according to needs and are not limited in this embodiment of the application.

[0141] In this way, the user can complete the blood pressure calibration in the standard scenario by triggering the blood pressure calibration process in the standard scenario of the smart wearable device. Combined with the analysis of the factors affecting blood pressure above, it can be seen that the standard scenario covers multiple calibration scenarios that can induce changes in blood pressure influencing factors such as heart rate, stroke volume, and total peripheral resistance. The user can complete the blood pressure calibration in the standard scenario without performing other settings. The operation is simple and convenient, and the calibration effect is good. For example, when the user uses a smart wearable watch for blood pressure calibration for the first time, he can select the standard scenario and complete the blood pressure calibration in the standard scenario. The characteristics of the user's blood pressure influencing factors can be obtained through one calibration, thereby ensuring that the blood pressure value prediction in the subsequent measurement stage is more accurate.

[0142] Figure 8 FIG. 4 shows a blood pressure calibration flow chart in a standard scenario according to an embodiment of the present application; FIG. Figure 8As shown, after starting blood pressure calibration in the standard scenario, the smart wearable watch can sequentially perform step 1101, blood pressure calibration in the lying down scenario, step 1102, blood pressure calibration in the sitting down scenario, step 1103, blood pressure calibration in the mental activity scenario, step 1104, blood pressure calibration in the relaxation / resting scenario, and step 1105, blood pressure calibration in the anaerobic exercise scenario; thereby completing the blood pressure calibration in the standard scenario. The present embodiment does not limit the execution order of these steps.

[0143] For example, the smart wearable watch can execute the above Figure 5 and Figure 6 Follow the process in the previous step to complete the blood pressure calibration in the lying down scene, sitting down scene, mental activity scene, relaxation / rest scene and anaerobic exercise scene in turn. At this point, the blood pressure calibration process in the standard scene is completed.

[0144] In one possible implementation, the smart wearable watch can measure the user's calibrated blood pressure value and collect the user's physiological signals in each calibration scenario under the user-defined scenario.

[0145] Among them, the custom scene may include the above-mentioned multiple preset calibration scenes, and the execution order of each calibration scene. The calibration scene categories, quantity, and execution order of each calibration scene included in the custom scene can be set by the user. For example, the user can select multiple calibration scenes from the preset multiple candidate calibration scenes, and use the preset order of each calibration scene as the execution order of each calibration scene. If the user selects the sitting scene, lying scene, mental activity scene, relaxation / rest scene, and anaerobic exercise scene in sequence, the custom scene may include: executing the sitting scene, lying scene, mental activity scene, relaxation / rest scene, and anaerobic exercise scene in sequence.

[0146] For example, Figure 7 As shown, after the smart wearable watch 101 enters the calibration mode, the user can trigger the instruction to calibrate the blood pressure in the custom scene by clicking the virtual button 1002 of the custom scene. The smart wearable watch 101 responds to the instruction and executes the blood pressure calibration process in the custom scene.

[0147] The custom scene can be a calibration scene selected from multiple calibration scenes provided by the smart wearable watch, for example, Figure 9 A schematic diagram of setting a custom scene according to an embodiment of the present application is shown. The user can enter the custom scene by clicking the virtual button 1002 of the custom scene in 9 (a). Figure 9(b) The custom selection page, at this time, the smart wearable watch display can show the user the calibration scenes available for selection, and the calibration scenes can include the multiple calibration scenes shown in Table 1 above (only the sitting scene, lying scene, and mental activity scene are shown in the figure). The user can select the custom scene according to his daily behavior habits by sliding up and down, clicking on the virtual button, etc. In this way, the user selects the calibration scene according to his most frequent daily activities. For example, if the user works in front of the computer every day, he can select the sitting scene and the mental activity scene as the custom scene. In this way, the user can choose the most suitable and matching calibration scene according to his daily activities to complete the calibration, which can make the calibration more personalized and targeted, effectively reduce the calibration time, and improve the user experience.

[0148] Figure 10 FIG. 1 shows a blood pressure calibration flow chart in a custom scenario according to an embodiment of the present application; FIG. Figure 10 As shown, if the user-defined scene includes: executing the sitting scene, lying scene, mental activity scene, and anaerobic exercise scene in sequence, after starting the blood pressure calibration in the customized scene, the smart wearable watch can execute step 1301, blood pressure calibration in the lying scene, step 1302, blood pressure calibration in the sitting scene, step 1303, blood pressure calibration in the mental activity scene, and step 1304, blood pressure calibration in the anaerobic exercise scene in sequence; thereby completing the blood pressure calibration in the customized scene.

[0149] For example, the smart wearable watch can execute the above Figure 5 (a1) / 5(a2) / 5(a3)-5(e) process and Figure 6 Follow the process in the previous step to complete the blood pressure calibration in the lying down scene, sitting down scene, mental activity scene and anaerobic exercise scene in turn. At this point, the blood pressure calibration process in the user-defined scene is completed.

[0150] In one possible implementation, the smart wearable watch can determine the blood pressure calibration time based on user attributes.

[0151] The user attributes may include: whether the user is a person taking medication for hypertension or other persons. The blood pressure calibration time may be: the time for blood pressure calibration for each calibration scenario, or the calibration time for the above-mentioned standard scenario or custom scenario.

[0152] For example, Figures 11A-11B A schematic diagram of determining user attributes according to an embodiment of the present application is shown; Figure 11A As shown, in Figure 11A In (a), the user clicks the virtual button 401 of the calibration mode to trigger the smart wearable watch 101 to enter the calibration mode. Figure 11AIn (b), the display screen of the smart wearable watch 101 displays a virtual button 1401 for the person taking hypertension medication and a virtual button 1402 for other persons. The user can click the virtual button 1401 for the person taking hypertension medication to trigger a blood pressure calibration instruction for the person taking hypertension medication. In response to the instruction, the smart wearable watch 101 executes the blood pressure calibration process for the person taking hypertension medication. If the user clicks the virtual button 1402 for other persons, the smart wearable watch 101 executes the blood pressure calibration process for the standard scenario or the blood pressure calibration process for the custom scenario.

[0153] It should be noted that Figure 11A and Figure 11B The user chooses whether he is a person taking hypertension medication and the above Figure 8 The user can select the standard scene or the custom scene in no particular order, that is, the user can first select the standard scene or the custom scene, and then further select whether he is a person taking hypertension medication, such as Figure 11B As shown; you can also first select whether you are a person taking hypertension medication, and then further select a standard scenario or a custom scenario, such as Figure 11A shown.

[0154] In one possible implementation, if the user is taking medication for hypertension, blood pressure calibration can be performed at the time when the drug concentration in the user's body is highest and lowest. This allows for more accurate blood pressure measurements by taking into account the impact of drug concentration changes on the user's blood pressure.

[0155] The time points at which the drug concentration reaches its highest and lowest levels can be determined based on the instructions for the antihypertensive drug or relevant public information. Table 2 shows examples of the time points at which the concentrations of some antihypertensive drugs reach their peak.

[0156] Table 2: Time when some antihypertensive drugs reach peak concentration

[0157]

[0158]

[0159] For example, the user can click on the Figure 11A and Figure 11BThe virtual button 1401 for each person taking hypertension medication is selected according to the prompt information displayed on the display screen of the smart wearable watch or the voice prompt information. The prompt information may include options for different types, different doses and different times of taking hypertension drugs. The user can select the type, dose and time of taking the hypertension drugs taken. The smart wearable watch can determine the time point when the drug concentration reaches the highest and the time point when the concentration reaches the lowest after taking the medicine by searching the above-mentioned peak time description of the hypertension and antihypertensive drug concentration pre-stored in the smart wearable watch (such as Table 2) according to the type and dose of hypertension drugs. At the same time, the time point before the user takes the medicine can also be used as the time point when the concentration reaches the lowest; thereby reminding the user to perform the first blood pressure calibration before taking the medicine, and after the user completes the first blood pressure calibration, when the drug concentration reaches the highest time point, reminding the user to perform the second blood pressure calibration. The calibration can be manually triggered by the user at the reminded time.

[0160] Figure 12 A blood pressure calibration flow chart for a person taking medication for hypertension according to an embodiment of the present application is shown; the user is a person taking medication for hypertension, the name of the drug selected by the user through the prompt information is manidipine, the dosage is 20 mg, and the medication time is 9:00. The smart wearable watch can determine that the time point when the drug concentration reaches the highest is 4 hours after taking the medication, that is, 13:00, based on the above Table 2. The time point when the drug concentration reaches the lowest is about 7.9 hours after taking the medication, that is, about 17:00, and the time point when the second blood pressure calibration is determined to be 13:00. The blood pressure calibration time is 17:00. At the same time, if the user-defined scene includes: sitting scene, lying scene, mental activity scene, anaerobic exercise scene; the smart wearable watch reminds the user to perform blood pressure calibration at 13:00. If the user triggers the customized blood pressure calibration, the smart wearable watch can sequentially execute steps 1501, blood pressure calibration in the lying scene, step 1502, blood pressure calibration in the sitting scene, step 1503, blood pressure calibration in the mental activity scene, and step 1504, blood pressure calibration in the anaerobic exercise scene; thereby completing the first blood pressure calibration. After completing the first blood pressure calibration, the smart wearable watch can remind the user to perform a second blood pressure calibration at 17:00 through voice, vibration, display flashing, etc.; if the user triggers the customized blood pressure calibration, the smart wearable watch can sequentially execute steps 1501, blood pressure calibration in the lying scene, step 1502, blood pressure calibration in the sitting scene, step 1503, blood pressure calibration in the mental activity scene, and step 1504, blood pressure calibration in the anaerobic exercise scene; thereby completing the second blood pressure calibration.

[0161] For example, during the first blood pressure calibration or the second blood pressure calibration, the smart wearable watch can perform the above Figure 5(a1) / 5(a2) / 5(a3)-5(e) process and Figure 6 Follow the process in the previous step to complete the blood pressure calibration in the lying down scene, sitting still scene, mental activity scene and anaerobic exercise scene in turn. At this point, the first blood pressure calibration or the second blood pressure calibration is completed.

[0162] Step 303: The smart wearable watch calibrates the blood pressure value according to the calibration blood pressure values ​​in different calibration scenarios and the collected physiological signals.

[0163] For example, when the physiological signals collected in the calibration scenario include PPG signals, based on the pulse wave characteristic parameter method, the eigenvalues ​​of the preset features can be calculated using the PPG signals to obtain a feature matrix, and then the blood pressure values ​​corresponding to the feature matrix are marked using the calibration blood pressure values ​​obtained in the calibration scenario, thereby optimizing the correspondence between the eigenvalues ​​of the preset features of the PPG signals and the blood pressure values, thereby completing the calibration.

[0164] The following uses the pulse wave characteristic parameter method as an example to illustrate the blood pressure value calibration and the further blood pressure measurement process.

[0165] The smart wearable watch calculates the characteristic values ​​of preset features based on the PPG signal collected in the above-mentioned calibration scenario. The number of preset features can be one or more. For example, the preset features may include: pulse width, PPG signal period, PPG signal amplitude, peak value and trough value of the PPG signal waveform, etc.

[0166] The smart wearable watch generates a feature matrix corresponding to the calibration scenario based on the eigenvalues ​​of the preset features. The feature matrix can represent the user's physical state in the calibration scenario; and uses the calibrated blood pressure value obtained in the calibration scenario to mark the blood pressure value corresponding to the feature matrix. For example, the feature matrix can be expressed as Here, m represents the number of features, and j represents the number corresponding to the current calibration of the calibration scene. For example, in the above lying still scene, the calibration performed during lying still for 1 minute is regarded as one calibration of the scene. are the characteristic values ​​corresponding to different preset characteristics. The calibrated blood pressure value obtained in this calibration scenario is X j , then use X j mark Thus, the corresponding relationship between the calibrated blood pressure value and the characteristic matrix is ​​obtained, which is recorded as

[0167] In this way, by repeating the above operation for each blood pressure calibration under different calibration scenarios, the characteristic matrix corresponding to each blood pressure calibration under each calibration scenario and the calibrated blood pressure value corresponding to the characteristic matrix can be obtained, so that the correspondence between the calibrated blood pressure value and the characteristic matrix of the PPG signal can be established, and the characteristic matrix and the correspondence can be saved in the smart wearable watch. In this way, in subsequent blood pressure measurements, the user's current blood pressure value can be predicted based on the measured characteristic matrix of the user's current PPG signal and the correspondence between the stored calibrated blood pressure value and the PPG signal characteristics.

[0168] Furthermore, the monitoring method may also include: using the above-mentioned smart wearable watch after blood pressure calibration to measure the user's blood pressure. Among them, the user can achieve 24-hour continuous blood pressure monitoring by wearing the smart wearable watch after blood pressure calibration. The user can use the calibrated smart wearable watch to complete the blood pressure measurement in a certain scenario. For example, the user can sit still and click the above-mentioned Figure 4 The virtual button 402 of the measurement mode on the display screen of the smart wearable watch 101 triggers an instruction to enter the measurement mode. The smart wearable watch 101 responds to the instruction, enters the measurement mode, starts blood pressure measurement, collects PPG signals, predicts blood pressure values ​​based on the PPG signals, and displays the predicted blood pressure values.

[0169] In one possible implementation, the smart wearable watch collects PPG signals in measurement mode, and predicts blood pressure values ​​based on the PPG signals, which may include: calculating eigenvalues ​​of preset features based on the PPG signals, generating a feature matrix corresponding to the current measurement based on the eigenvalues ​​of the preset features, and determining one or more pre-stored feature matrices similar to the feature matrix corresponding to the current measurement among the pre-stored feature matrices, thereby obtaining the currently measured blood pressure value.

[0170] For example, a state space can be used to represent the range of a characteristic matrix. The characteristic matrices obtained under the aforementioned different calibration scenarios can serve as known points in the state space, with each known point corresponding to a calibrated blood pressure value. The characteristic matrix corresponding to the current measurement serves as the undetermined point in the state space. Thus, the blood pressure value of the undetermined point can be obtained based on the distance between the undetermined point and one or more known points in the state space, and the calibrated blood pressure values ​​corresponding to the known points. In this way, each blood pressure calibration performed under the aforementioned preset calibration scenario can induce changes in factors affecting blood pressure, such as the user's heart rate, stroke volume, cardiac output, and peripheral resistance, to obtain the characteristic matrices obtained under different calibration scenarios. These different characteristic matrices constitute the state space.

[0171] For example, Figure 13 A schematic diagram of a state space according to an embodiment of the present application is shown as follows: Figure 13As shown, each point in the state space represents the characteristic matrix of the PPG signal obtained in each calibration under different calibration scenarios. Different dots in the figure represent the characteristic matrix obtained in each calibration under the above standard scenario, among which dots with the same pattern represent the characteristic matrix obtained under the same calibration scenario. In this state space, the jth point The corresponding blood pressure value X j It can be expressed as in, Represents the value of the m features of the j-th point.

[0172] Figure 14 A schematic diagram of predicting blood pressure using state space according to an embodiment of the present application is shown as follows: Figure 14 As shown in the figure, during the current blood pressure measurement process, the characteristic matrix of the PPG signal obtained is (y1, y2, ..., y m ), which is the point represented by the triangle in the figure; the current blood pressure value can be recorded as Y(y1,y2,…,y m ), then the distance between the point in the state space corresponding to the user's blood pressure measurement and each point in the state space can be expressed as:

[0173]

[0174] Among them, m represents the number of features contained in the feature matrix, i represents the i-th feature in the feature matrix, X j represents the blood pressure value corresponding to the jth point in the state space, D j Indicates the distance between the point in the state space corresponding to this measurement and the j-th point in the state space, Represents the value of the i-th feature of the j-th point, y i Represents the value of the i-th feature of the feature matrix of the obtained PPG signal; p is an optional parameter and can generally be selected as 2.

[0175] The distances between the midpoint of the state space corresponding to the blood pressure measurement obtained above and each point in the state space (i.e., multiple D j (Y,X j )) is normalized so that Thus, n points in the state space are determined, namely Figure 14 For the points in the middle circular area, use the blood pressure values ​​corresponding to these n points, and use the formula: The blood pressure value Y of this blood pressure measurement can be predicted.

[0176] In this way, when measuring blood pressure, based on the characteristic matrix obtained in the current measurement scene and the pre-stored characteristic matrix, one or several calibration blood pressure values ​​that are most similar to the current measurement scene are selected, and these calibration blood pressure values ​​are weighted and summed to obtain the predicted blood pressure value currently measured. The weighting coefficient may be negatively correlated with the distance between the characteristic matrix corresponding to the calibration blood pressure value and the characteristic matrix obtained in the current measurement scene, that is, the smaller the distance, the greater the weight of the corresponding calibration blood pressure value, thereby increasing the blood pressure measurement range and improving the accuracy of blood pressure measurement.

[0177] It can be seen from the above calibration and prediction process that the more times the blood pressure is calibrated and the richer the calibration scenarios, the more points in the state space and the richer the distribution range, and the higher the accuracy of the blood pressure prediction; in the embodiment of the present application, in different calibration scenarios, the user's blood pressure influencing factors such as heart rate, stroke volume, total peripheral resistance, etc. change, and calibration is performed in different calibration scenarios, thereby enriching the number of points and distribution range in the state space, making the blood pressure prediction value obtained by actual measurement more accurate.

[0178] Furthermore, considering that the user's physical condition or the state of the user's environment will continue to change, the smart wearable watch can be calibrated for blood pressure regularly or irregularly to improve the accuracy of blood pressure measurement by the calibrated smart wearable watch.

[0179] For example, the smart wearable watch can remind the user to calibrate the blood pressure when it detects that the blood pressure value measured by the smart wearable watch is abnormal. For example, when the user configures the smart wearable watch for continuous blood pressure monitoring, the airbag and pressure sensor of the smart wearable watch can measure the user's blood pressure value regularly (such as every day) and compare it with the blood pressure value measured by the smart wearable watch through the PPG sensor at the same time point or a nearby time point. If the blood pressure exceeds the preset threshold, the user is reminded to calibrate the blood pressure, thereby realizing self-monitoring of the blood pressure measurement accuracy of the smart wearable watch.

[0180] Exemplarily, the smart wearable watch can periodically remind the user to calibrate blood pressure; wherein, the period can be a period preset by the smart wearable watch at the factory, or it can be a period determined by the smart wearable watch in response to the user's blood pressure calibration period setting operation. For example, when the user uses the blood pressure measurement function of the smart wearable watch for the first time, the smart wearable watch can display the blood pressure calibration period setting options to the user through the display screen, such as: 1 day, 1 week, one month, etc. The smart wearable watch determines the blood pressure calibration period according to the user's period selection operation, and then reminds the user to calibrate blood pressure when the blood pressure calibration period is met.

[0181] For example, the user can also choose to calibrate the blood pressure on his own. For example, when the user uses the blood pressure measurement function of the smart wearable watch for the first time, or when the user has not calibrated the blood pressure for a long time, the smart wearable watch can remind the user to calibrate the blood pressure, and the user can choose whether to calibrate the blood pressure on his own. For another example, the user can calibrate the blood pressure when he feels that his physical condition or the state of the user's environment has changed.

[0182] In an embodiment of the present application, a prompt message is used to prompt the user to complete physical activities that conform to multiple calibration scenarios. After the user completes physical activities that conform to different calibration scenarios, the user's blood pressure influencing factors such as heart rate, stroke volume, and total peripheral resistance change. During the blood pressure calibration phase, the user's calibrated blood pressure value is measured in each calibration scenario and the corresponding physiological signals are collected to fully capture the changes in the user's blood pressure influencing factors and achieve blood pressure calibration in multiple calibration scenarios. During the blood pressure measurement phase, the measured user's blood pressure value is determined based on the collected physiological signals, as well as the calibrated blood pressure values ​​and corresponding physiological signals in each of the above-mentioned calibration scenarios. The blood pressure value is more accurate, thereby achieving accurate measurement of the user's blood pressure. At the same time, the blood pressure calibration process does not require the use of other equipment, is easy to operate, and improves the user experience.

[0183] The following combination Figure 2 The application scenario shown in the figure illustrates the blood pressure monitoring method provided by this application.

[0184] Figure 15 A flow chart of a blood pressure monitoring method according to an embodiment of the present application is shown as follows: Figure 15 As shown, the method may include the following steps:

[0185] Step 1801: The smart wearable watch enters a calibration mode in response to a user's instruction.

[0186] The method of entering the calibration mode in this step can refer to the above Figure 3 The relevant introduction in step 301 will not be repeated here.

[0187] For example, in Figure 2 In the embodiment, if the smart wearable watch 101 can be connected to the blood pressure monitor 102 via a distance communication method such as Bluetooth or WIFI, after the smart wearable watch enters the calibration mode, it can send an instruction to prepare for blood pressure measurement to the blood pressure monitor, thereby making the blood pressure monitor ready to measure blood pressure.

[0188] For example, in Figure 2 In the process, when the smart wearable watch 101 enters the calibration mode, the user can manually operate the blood pressure monitor 102 to prepare for measuring blood pressure.

[0189] Step 1802: The smart wearable watch collects the user's physiological signals under different calibration scenarios and obtains the calibrated blood pressure values ​​measured by the blood pressure monitor.

[0190] In this step, the smart wearable watch collects the user's physiological signals under different preset calibration scenarios. At the same time, the blood pressure monitor measures the user's blood pressure value using the oscillometric method as the calibration blood pressure value.

[0191] In one possible implementation, the smart wearable watch collects the user's physiological signals in different calibration scenarios and obtains the calibrated blood pressure values ​​measured by the blood pressure monitor, which may include: the blood pressure monitor can measure the calibrated blood pressure value in the calibration scenario by the oscillometric method, and at the same time, the smart wearable watch collects the user's physiological signals; wherein, the time when the blood pressure monitor measures the calibrated blood pressure value in the calibration scenario can be before the time when the user's physiological signals in the scenario are collected, or after the time when the user's physiological signals in the scenario are collected; the time when the blood pressure monitor measures the calibrated blood pressure value in the calibration scenario can also be the same as the time when the user's physiological signals in the scenario are collected, that is, the user's physiological signals are collected while measuring the calibrated blood pressure value.

[0192] For example, the smart wearable watch can send an instruction to the blood pressure monitor to start measuring blood pressure; at the same time, the PPG sensor of the smart wearable watch starts working to collect the user's PPG signal, or the PPG sensor and ECG sensor of the smart wearable watch start working to collect the user's PPG signal and ECG signal. After receiving the instruction, the blood pressure monitor obtains the calibrated blood pressure value in this scenario through the oscillometric method and sends the calibrated blood pressure value to the smart wearable device. For example, when the smart wearable watch and the blood pressure monitor are worn on different sides of the user's arms respectively, the smart wearable watch sends an instruction to the blood pressure monitor to start measuring blood pressure while starting to collect the user's physiological signals. In this way, the user's calibrated blood pressure and physiological signals can be measured synchronously.

[0193] For example, the smart wearable watch can send an instruction to the blood pressure monitor to start measuring blood pressure. After receiving the instruction, the blood pressure monitor obtains the calibrated blood pressure value in the scenario through the oscillometric method and sends the calibrated blood pressure value to the smart wearable device. After receiving the calibrated blood pressure value, or after a certain interval, the smart wearable device starts to collect the user's physiological signals in the calibration scenario. For example, when the smart wearable watch and the blood pressure monitor are worn on different arms of the user, the smart wearable watch can start working after receiving the calibrated blood pressure value or after an interval of 30 seconds, and collect the user's PPG signal, or the PPG sensor and ECG sensor of the smart wearable watch can start working and collect the user's PPG signal and ECG signal. In this way, the influence of air pressure changes when the blood pressure monitor measures blood pressure on the collected physiological signals can be avoided, thereby improving the accuracy of the measurement.

[0194] For example, the user can manually trigger the blood pressure monitor to start measuring, and at the same time, the PPG sensor of the smart wearable watch starts working to collect the user's PPG signal, or the PPG sensor and ECG sensor of the smart wearable watch start working to collect the user's PPG signal and ECG signal. After the blood pressure monitor and the smart wearable watch have completed the measurement, the user can input the calibrated blood pressure value obtained by the blood pressure monitor into the smart wearable watch. For example, when the smart wearable watch and the blood pressure monitor are worn on different arms of the user respectively, the user can manually trigger the blood pressure monitor to start measuring, and at the same time, the smart wearable watch starts collecting the user's physiological signals. In this way, the user's calibrated blood pressure and physiological signals can be measured synchronously. For example, the user can manually trigger the blood pressure monitor to measure and obtain the calibrated blood pressure value in the scenario; then, the user can input the calibrated blood pressure value into the smart wearable watch. After the smart wearable watch receives the calibrated blood pressure value input by the user, or after a certain interval (such as 30S), it starts to collect the user's physiological signals in the calibration scenario. Alternatively, the user can trigger the blood pressure measurement function of the smart wearable watch by clicking the start button or other operations, so that the smart wearable watch starts to collect the user's physiological signals in the calibration scenario. After the collection is completed, the user enters the calibrated blood pressure value in the smart wearable watch.

[0195] In this step, the calibration scene, physiological signals, etc. can refer to the above Figure 3 The relevant introduction in step 301 will not be repeated here.

[0196] The following uses the sitting still scene, lying still scene, mental activity scene, relaxation / rest scene, and anaerobic exercise scene as examples to illustrate the process of users completing blood pressure calibration using a smart wearable watch and a blood pressure monitor in different calibration scenarios.

[0197] For example, when the smart wearable watch can be connected to the blood pressure monitor via Bluetooth or WIFI, the blood pressure calibration process in the sitting scene, lying scene, mental activity scene, relaxation / rest scene, and anaerobic exercise scene can refer to the above Figure 5-Figure 6 The relevant introduction in the Figure 5-Figure 6 The difference is that when the words "Blood pressure is being measured, please keep still" are displayed on the display screen of the smart wearable watch, the smart wearable watch can send an instruction to the blood pressure monitor. The blood pressure monitor measures the user's calibrated blood pressure value in response to the instruction. At the same time, the smart wearable watch starts to collect the user's physiological signals; the blood pressure monitor sends the calibrated blood pressure value to the smart wearable watch. Alternatively, the smart wearable watch can also send an instruction to the blood pressure monitor. The blood pressure monitor measures the user's calibrated blood pressure value in response to the instruction and sends the calibrated blood pressure value to the smart wearable watch. After receiving the calibrated blood pressure value, the smart wearable watch starts to collect the user's physiological signals, or starts to collect the user's physiological signals at certain intervals. In this way, the user can complete the calibration process through simple operations, which improves the user experience.

[0198] For example, when the smart wearable watch and blood pressure monitor are worn on different arms of the user, and the user triggers the blood pressure monitor to measure manually, the blood pressure calibration process in the sitting scene, lying scene, mental activity scene, relaxation / rest scene, and anaerobic exercise scene is as follows: Figure 16-17 As shown in . In this way, there is no restriction on the configuration of the blood pressure monitor, the economy is high, and the scope of application is expanded.

[0199] Figure 16 A schematic diagram of blood pressure calibration under multiple calibration scenarios according to an embodiment of the present application is shown; the smart wearable watch provides prompt information for sitting still scenario, lying still scenario, mental activity scenario, and relaxation / rest scenario, thereby prompting the user to complete physical activities that meet the requirements of each calibration scenario; the prompt method can be found in the relevant description above. Figure 16 (a1)-16(a4) show the prompt information of the sitting scene, lying scene, mental activity scene, and relaxation / rest scene. The content of the prompt information can be referred to the relevant description above. After prompting the user to complete the physical activities in the calibration scene, such as Figure 16 As shown in (b), the words "Countdown is about to begin" are displayed on the display screen of the smart wearable watch, thereby reminding the user to prepare for physical activities that conform to the calibration scenario. In addition, the smart wearable watch can also remind the user that the countdown is about to begin in the form of language broadcast; Figure 16As shown in (c), the display screen of the smart wearable watch may prompt a "countdown" to remind the user to continue the physical activity that conforms to the calibration scenario, and may also remind the user of the time it takes to perform the physical activity that conforms to the calibration scenario; the method of prompting the "countdown" may refer to the relevant description above; Figure 16 As shown in (d), in the final stage of the countdown, for example, when entering the last 5 seconds, the words "Please trigger the blood pressure monitor to measure" can be displayed on the display screen of the smart wearable watch to remind the user that the blood pressure measurement of the smart wearable watch is about to begin. The blood pressure monitor can be triggered to perform the blood pressure measurement operation by clicking or pressing a button. In addition, the smart wearable watch can also make corresponding reminders in the form of language broadcasts, screen flashing, etc. Figure 16 As shown in (e), the words "Blood pressure is being measured, please keep still" are displayed on the display screen of the smart wearable watch, thereby reminding the user to keep still. In addition, the smart wearable watch can also remind the user to keep still in the form of language broadcast. For example, in a lying down scene, the user can be reminded to keep lying still, and in a sitting still scene, a mental activity scene, and a relaxation / resting scene, the user can be reminded to keep sitting still. At this time, the PPG sensor (or, PPG sensor and ECG sensor) of the smart wearable watch collects the user's physiological signals, and at the same time, the blood pressure monitor measures the user's blood pressure. Figure 16 As shown in (f), the words "Measurement completed, please enter the blood pressure value displayed by the blood pressure monitor" are displayed on the display screen of the smart wearable watch, thereby reminding the user that the blood pressure measurement of the smart wearable watch has been completed, and reminding the user to enter the blood pressure value displayed by the blood pressure monitor into the smart wearable watch. In addition, the smart wearable watch can also make corresponding reminders in the form of language broadcast. Figure 16 As shown in (g), after the smart wearable watch receives the blood pressure value input by the user, the words "Measurement Completed" are displayed on the display screen of the smart wearable watch, thereby reminding the user that a blood pressure measurement in the calibration scenario is completed. In addition, the smart wearable watch can also remind the user that a blood pressure measurement in the calibration scenario is completed in the form of language broadcast.

[0200] Figure 17 A schematic diagram of blood pressure calibration in an anaerobic exercise scenario according to an embodiment of the present application is shown; the smart wearable watch provides prompt information for the anaerobic exercise scenario, thereby prompting the user to complete physical activities that meet the anaerobic exercise scenario; after starting blood pressure calibration in the anaerobic exercise scenario, the following steps are executed in sequence: Figure 17 (a)-17(d) process, such as Figure 17As shown in (a), the words "Please do the horse stance to the limit, then sit down and click to start measuring, and trigger the blood pressure monitor to measure" and a virtual button for starting measurement are displayed on the display screen of the smart wearable watch, thereby reminding the user that in this calibration scenario, the horse stance must be done to the limit, and then sit down and click the virtual button for starting measurement. At the same time, the user is reminded that the blood pressure monitor can be triggered to perform blood pressure measurement operations by clicking, pressing, etc. Other ways to remind the user to do the horse stance to the limit can refer to the relevant statements in the previous text; the user triggers the blood pressure monitor to perform blood pressure measurement operations by clicking, etc., on the premise that the user does the horse stance to the limit and maintains a sitting position, and at the same time clicks the start button to trigger the start blood pressure measurement instruction. The smart wearable watch responds to the instruction and starts blood pressure measurement, as shown in FIG. Figure 17 As shown in (b), the words "Blood pressure is being measured, please keep still" are displayed on the display screen of the smart wearable watch, thereby reminding the user to keep still. In addition, the smart wearable watch can also remind the user to keep sitting still in the form of language broadcast; at this time, the PPG sensor (or, PPG sensor and ECG sensor) of the smart wearable watch collects the user's physiological signals, and at the same time, the blood pressure monitor measures the user's blood pressure. Figure 17 As shown in (c), the words "Measurement completed, please enter the blood pressure value displayed by the blood pressure monitor" are displayed on the display screen of the smart wearable watch, thereby reminding the user to enter the blood pressure value displayed by the blood pressure monitor into the smart wearable watch after the blood pressure measurement of the blood pressure monitor is completed. In addition, the smart wearable watch can also make corresponding reminders in the form of language broadcast. Figure 17 As shown in (d), the words "measurement completed" are displayed on the display screen of the smart wearable watch, thereby reminding the user that a blood pressure measurement in an anaerobic exercise scenario is completed. In addition, the smart wearable watch can also remind the user that a blood pressure measurement in an anaerobic exercise scenario is completed in the form of language broadcast.

[0201] In one possible implementation, the smart wearable watch can collect the user's physiological signals in a standard scenario and obtain the calibrated blood pressure value measured by the blood pressure monitor.

[0202] The specific content of the standard scenario can be found in the previous article and will not be repeated here.

[0203] For example, the smart wearable watch can execute the above Figure 16 and Figure 17 The blood pressure calibration process in the standard scenario is completed by completing the blood pressure calibration in the lying down scenario, sitting down scenario, mental activity scenario, relaxation / resting scenario and anaerobic exercise scenario in turn.

[0204] In one possible implementation, the smart wearable watch can collect the user's physiological signals in a user-defined scenario and obtain the calibrated blood pressure value measured by the blood pressure monitor.

[0205] The specific content of the custom scene can be found in the previous introduction and will not be repeated here.

[0206] For example, the smart wearable watch can execute the above Figure 16 (a1) / 16(a2) / 16(a3) process and Figure 17 The process completes the blood pressure calibration in the lying down scene, sitting down scene, mental activity scene, and anaerobic exercise scene in turn. At this point, the blood pressure calibration process in a user-defined scene is completed.

[0207] In one possible implementation, the smart wearable watch can determine the blood pressure calibration time based on user attributes.

[0208] Among them, the user attributes, the method of determining the blood pressure calibration time, etc. can be referred to the relevant introduction in the previous article and will not be repeated here.

[0209] For example, the smart wearable watch can perform the operations of the above-mentioned standard scenario or custom scenario at the determined blood pressure calibration time.

[0210] Step 1803: The smart wearable watch calibrates the blood pressure value according to the calibration blood pressure values ​​in different calibration scenarios and the collected physiological signals.

[0211] The specific implementation method of this step can refer to the above Figure 3 The relevant introduction in step 303 will not be repeated here.

[0212] In an embodiment of the present application, a prompt message is used to prompt the user to complete physical activities that conform to multiple calibration scenarios; after the user completes physical activities that conform to different calibration scenarios, the user's blood pressure influencing factors such as heart rate, stroke volume, and total peripheral resistance change. During the blood pressure calibration phase, the user's calibrated blood pressure values ​​under each calibration scenario are received and the corresponding physiological signals are collected, fully capturing the changes in the user's blood pressure influencing factors and achieving blood pressure calibration under multiple calibration scenarios; during the blood pressure measurement phase, the measured user's blood pressure value is determined based on the collected physiological signals, as well as the calibrated blood pressure values ​​and corresponding physiological signals under each of the above-mentioned calibration scenarios, with higher accuracy, thereby achieving accurate measurement of the user's blood pressure; at the same time, the blood pressure calibration process can use the blood pressure value measured by a medically certified blood pressure monitor as the calibrated blood pressure value, which can further improve calibration accuracy.

[0213] Figure 18 A flow chart of a blood pressure monitoring method according to an embodiment of the present application is shown. The method can be executed on an electronic device, for example, Figure 1 The scenario shown is executed on the wearable device, such as Figure 18 As shown, the method may include the following steps:

[0214] Step 1901: In response to a first operation, the electronic device enters a calibration mode;

[0215] Step 1902: Display a first graphical user interface, where the first graphical user interface is used to prompt the user to perform a first action;

[0216] Step 1903: measuring a first blood pressure value and collecting first physiological indicator information;

[0217] Step 1904: Display a second graphical user interface, where the second graphical user interface is used to prompt the user to perform a second action;

[0218] Step 1905: measuring a second blood pressure value and collecting second physiological indicator information;

[0219] Step 1906: In response to the second operation, the electronic device enters a measurement mode;

[0220] Step 1907: collecting third physiological indicator information;

[0221] Step 1908: Determine a third blood pressure value corresponding to the third physiological indicator information based on the first blood pressure value, the second blood pressure value, the first physiological indicator information, and the second physiological indicator information.

[0222] According to an embodiment of the present application, in response to a first operation of a user, the electronic device enters a calibration mode and displays a first graphical user interface; measures a first blood pressure value when the user performs a first action based on the prompt of the first graphical user interface, and collects first physiological indicator information when the user performs the first action; displays a second graphical user interface, measures a second blood pressure value when the user completes a second action based on the prompt of the second graphical user interface, and collects second physiological indicator information when the user performs the second action; in response to the second operation of the user, the electronic device enters a measurement mode, collects second physiological indicator information, and determines a third blood pressure value corresponding to the third physiological indicator information based on the first blood pressure value, the second blood pressure value, the first physiological indicator information, and the second physiological indicator information. In this way, during the calibration phase, by displaying multiple graphical user interfaces (including the first graphical user interface and the second graphical user interface) and prompting the user to perform different actions (including the first action and the second action), the user's blood pressure influencing factors such as heart rate, stroke volume, total peripheral resistance, etc. change. The blood pressure values ​​(including the first blood pressure value and the second blood pressure value) of the user when performing different actions are measured respectively, and physiological indicator information (including the first physiological indicator information and the second physiological indicator information) is collected to fully capture the changes in the factors affecting the user's blood pressure and realize blood pressure calibration in multiple calibration scenarios; in the measurement stage, according to the multiple blood pressure values ​​and multiple physiological indicator information obtained in the calibration stage, the blood pressure value (i.e., the third blood pressure value) corresponding to the collected physiological indicator information (i.e., the third physiological indicator information) is determined, and the accuracy of this blood pressure value is higher, thereby realizing accurate measurement of the user's blood pressure.

[0223] The first operation may be an operation that triggers the wearable device to enter the calibration mode. The user may perform the first operation by clicking a virtual button on the display screen of the wearable device, pressing a physical button, using a voice command, using a quick gesture, or any other method. For example, the user may click the above Figure 4 The calibration mode virtual button 401 on the display screen, or by clicking to trigger the above Figure 7 The first operation is performed by the virtual button 1001 of the standard scene on the display screen. After the wearable device receives the first operation, it can respond to the first operation and perform the calibration mode. Step 1901 can refer to the above Figure 3 Related examples or descriptions of steps 301 and 302.

[0224] It should be noted that after the electronic device enters the calibration mode, the first graphical user interface and the second graphical user interface displayed are only examples, and other graphical user interfaces for prompting the user to perform corresponding actions may also be displayed. The embodiment of the present application is not limited to this. The graphical user interface may include the interface displayed in the calibration scenario above; for example, the above-mentioned Figure 5 (a1), Figure 5(a2), Figure 5 (a3), Figure 5 (a4) and Figure 6 (a) Any two or more graphical user interfaces. It is understood that after the calibration mode, the user can perform multiple actions according to the prompts of the multiple graphical user interfaces, including but not limited to the first action and the second action, wherein the actions can include the physical activities mentioned above, which can be referred to in Table 1, Figure 5 、 Figure 6 The relevant expressions in , for example, can be Figure 5 As shown in (a3), “Please continue to subtract 7 from 500 for one minute.” The embodiments of the present application do not limit the specific form of each action, as long as it can induce the user to achieve changes in blood pressure influencing factors through physical activity.

[0225] The embodiment of the present application does not limit the prompt information displayed by each graphical user interface and the order of displaying each graphical user interface that prompts the user to perform corresponding actions. The prompt information displayed by the graphical user interface can refer to the above. In one example, the multiple graphical user interfaces displayed can be graphical user interfaces corresponding to pre-set standard scenarios, and can refer to the above. Figure 7 、 Figure 8 For example, the order of displaying multiple graphical user interfaces can refer to the above Figure 8 The order of the calibration scenarios included in the standard scenario is shown in Figure 1. In this way, in the calibration mode, multiple actions that can induce changes in blood pressure influencing factors such as heart rate, stroke volume, and total peripheral resistance are included. The user does not need to perform other settings. By performing the first operation, multiple actions can be performed according to the prompts of the graphical user interface, thereby completing blood pressure calibration in multiple calibration scenarios. The operation is simple and convenient, and the calibration effect is good.

[0226] The first blood pressure value and the second blood pressure value can be obtained by measurement, and may include the calibrated blood pressure value mentioned above. In one example, the wearable device may be provided with a component for measuring the first blood pressure value, for example Figure 1 The airbag and pressure sensor can be used to measure the first blood pressure value and the second blood pressure value by oscillometric method, and the calibration can be performed with the first blood pressure value and the second blood pressure value with relatively high accuracy to improve the accuracy of the calibration.

[0227] The first physiological indicator information, the second physiological indicator information, and the third physiological indicator information may include any information that can reflect the physiological indicators of the human body, such as the physiological signals mentioned above, such as PPG, ECG, IPG, SCG, BCG, heart sounds and other physiological signals. The first physiological indicator information, the second physiological indicator information, and the third physiological indicator information can be collected by sensors provided by the wearable device itself (such as PPG sensors). The first physiological indicator information, the second physiological indicator information, and the third physiological indicator information are not direct blood pressure measurement results, and include physiological indicator information other than blood pressure values.

[0228] Step 1901-step 1907, refer to the above Figure 3 Relevant examples or descriptions in steps 301 and 302 are shown.

[0229] Among them, the second operation can represent an operation to trigger the wearable device to enter the measurement mode. In the measurement mode, it can include taking a blood pressure measurement once or continuously monitoring the blood pressure, etc. The user can trigger the second operation by clicking a virtual button on the display screen of the wearable device, pressing a physical button, a voice command, a shortcut gesture, etc. The wearable device responds to the second operation and enters the measurement mode. For example, the user can click the above Figure 4 The virtual button 402 of the measurement mode on the display screen triggers the second operation. The third physiological indicator information may include the physiological signals of the user measured by the sensors of the wearable device when measuring blood pressure, such as PPG, ECG, IPG, SCG, BCG, heart sounds and other physiological signals. The third blood pressure value represents the final measurement result of the wearable device on the user's blood pressure value. In step 1908, you can refer to the above Figure 3 The relevant examples or descriptions in step 303 in the calibration process should be understood by those skilled in the art that the method for determining the third blood pressure value corresponding to the collected third physiological indicator information based on the first blood pressure value, the second blood pressure value, the first physiological indicator information, and the second physiological indicator information collected during the calibration phase is not limited to the above examples and can be selected and adjusted as needed. In addition, the third blood pressure corresponding to the collected third physiological indicator information can also be determined based on the blood pressure values ​​of the user performing multiple (more than two) exercises in the calibration scenario and the corresponding multiple (more than two) physiological indicator information.

[0230] In one possible implementation, after the electronic device enters the calibration mode in response to the first operation, it also includes: displaying a third graphical user interface, wherein the third graphical user interface displays options for multiple calibration scenarios; and displaying the first graphical user interface in response to the user's selection operation of the calibration scenario.

[0231] In the embodiment of the present application, the user can trigger the first operation in the manner described above, for example, by clicking the above Figure 7 The virtual button 1002 of the custom scene on the display screen triggers the first operation. In response to the first operation, the wearable device displays a third graphical user interface. For example, the third graphical user interface can be as follows: Figure 9 In response to the user's selection of a calibration scene, the graphical user interfaces corresponding to the calibration scenes selected by the user are displayed in sequence according to the preset order of the calibration scenes in the plurality of calibration scenes, thereby prompting the user to perform actions under each calibration scene; wherein the calibration scene selected by the user may include any number of calibration scenes in the plurality of calibration scenes displayed by the third graphical user interface, for example, the plurality of calibration scenes may refer to the aforementioned Figure 9 、 Figure 10 In the calibration process, the user can select the most suitable and matching calibration scene according to their daily activities, which can make the calibration more personalized and targeted, effectively reduce the calibration time and improve the user experience.

[0232] Illustratively, the calibration scenario corresponds to one or more of a calibration scenario for the user's physical condition and a calibration scenario for the state of the user's environment. Thus, in different calibration scenarios, the user's physical condition and the state of the user's environment vary, and accordingly, factors influencing the user's blood pressure, such as heart rate, stroke volume, and total peripheral resistance, vary. By inducing changes in the factors influencing the user's blood pressure based on the different physical conditions or environmental conditions of the user, the changes in the factors influencing the user's blood pressure are fully captured, enabling blood pressure calibration under different user physical conditions or environmental conditions.

[0233] Exemplarily, the calibration scenes corresponding to the user's physical state may include one or more of a sitting scene, a lying scene, a standing scene, a mental activity scene, a relaxation / resting scene, an anaerobic action scene, and an aerobic action scene, wherein the sitting scene, the lying scene, and the standing scene are scenes of the user in a quiet sitting, lying, and standing posture, respectively, and these scenes represent the user's physical state in different quiet postures; the mental activity scene represents the user's physical state of sympathetic nerve excitement, which stimulates an increase in heart rate, an increase in cardiac stroke volume, constriction of veins to increase venous return, constriction of arteries to increase peripheral resistance, and increased blood pressure; the relaxation / resting scene represents the user's physical state of parasympathetic nerve excitement, which stimulates a decrease in heart rate and lowers blood pressure; the anaerobic action scene represents the user's physical state of increasing cardiac output, increasing peripheral resistance, and rapidly increasing blood pressure; the aerobic action scene represents the user's physical state of increasing heart rate, increasing cardiac output, reducing peripheral resistance, and increasing blood pressure. For example, calibration scenarios corresponding to the user's environmental conditions can include one or more of cold and hot environments. In cold environments, peripheral vasoconstriction increases peripheral resistance, raising blood pressure. In hot environments, peripheral vasodilation reduces peripheral resistance and lowers blood pressure. Thus, in different scenarios, factors influencing a user's blood pressure, such as heart rate, stroke volume, and total peripheral resistance, change. The multiple calibration scenarios provided can comprehensively cover these changes in factors influencing a user's blood pressure, enabling blood pressure calibration in different scenarios and improving the accuracy of blood pressure measurements using calibrated wearable devices.

[0234] In a possible implementation, after displaying the first graphical user interface, the method further includes: displaying a fourth graphical user interface, wherein the fourth graphical user interface displays timing information. It is understandable that after displaying the second graphical user interface or other graphical user interfaces for instructing the user to perform corresponding movements, a graphical user interface for displaying timing information can be displayed; wherein the timing information can include countdown or countup, which is not limited in this embodiment of the present application. The fourth graphical user interface can refer to the above-mentioned Figure 5 、 Figure 6 For example, the relevant expressions in Figure 5 (c) In this way, the fourth graphical user interface displays timing information, thereby prompting the user to indicate the time the first action has been performed or the time the first action still needs to be performed. The user can complete the indicated exercise according to the prompt of the graphical user interface, thereby completing the blood pressure measurement in the corresponding calibration scenario, which is simple and convenient, and improves the user experience.

[0235] In one possible implementation, in step 1908, determining the third blood pressure value corresponding to the third physiological indicator information based on the first blood pressure value, the second blood pressure value, the first physiological indicator information and the second physiological indicator information may include: determining the similarity between the first physiological indicator information and the third physiological indicator information, and the similarity between the second physiological indicator information and the third physiological indicator information; determining a target similarity greater than a second threshold, and a target physiological indicator information corresponding to the target similarity; performing weighted summation on the target blood pressure values ​​corresponding to the target physiological indicator information to obtain the third blood pressure value, wherein the weight of the target blood pressure value is positively correlated with the similarity between the corresponding target physiological indicator information and the third physiological indicator information.

[0236] In an embodiment of the present application, when measuring the user's blood pressure using a calibrated wearable device, the target physiological indicator information whose similarity is greater than a second threshold value among the multiple physiological indicator information obtained in the calibration phase is determined, and the target blood pressure values ​​corresponding to the target physiological indicator information whose similarity is greater than the second threshold value are weightedly summed to obtain the user's third blood pressure value; in this way, one or several target blood pressure values ​​obtained in the calibration phase that are most similar to the current measurement scene are selected, and these target blood pressure values ​​are weightedly summed to predict the currently measured third blood pressure value, and the weight of each target blood pressure value is positively correlated with the similarity between the corresponding target physiological indicator information and the third physiological indicator information; that is, the higher the similarity, the greater the weight of the corresponding target blood pressure value, thereby increasing the blood pressure measurement range and improving the accuracy of blood pressure measurement.

[0237] Among them, the similarity between the third physiological indicator information and each first physiological indicator information (or second physiological indicator information) can be expressed in any appropriate way, and this application does not impose any restrictions on this, as long as it can reflect the similarity between the third physiological indicator information and the first physiological indicator information, and then reflect the similarity between the scene of collecting the third physiological indicator information and the scene of collecting the first physiological indicator information. For example, the similarity can be represented by the distance between the feature matrix corresponding to the first physiological indicator information and the feature matrix corresponding to the third physiological indicator information obtained in the current measurement scene, such as the above Figure 13 The distance between the point of the characteristic matrix corresponding to the first physiological indicator information and the point of the characteristic matrix corresponding to the third physiological indicator information obtained in the current measurement scene in the state space shown in . The second threshold value can be pre-set, and the embodiment of the present application does not limit this; determine the target physiological indicator information corresponding to each point whose distance from the point of the characteristic matrix corresponding to the third physiological indicator information is greater than the second threshold, so as to select one or several target blood pressure values ​​that are most similar to the current measurement scene; the smaller the distance, the greater the weight of the corresponding target blood pressure value; the third blood pressure value of the user is obtained by weighted summation of each target blood pressure value; the specific implementation process can refer to the previous text Figure 13-14 Related statements in .

[0238] In one possible implementation, the method may further include: obtaining the type, dosage, and time of medication taken by the user; determining a first moment and a second moment based on the type, dosage, and time of medication; and displaying a fifth graphical user interface at the first moment and the second moment, respectively, wherein the fifth graphical user interface is used to prompt the user to perform the first operation.

[0239] In the embodiment of the present application, the first moment may represent the time point when the drug concentration in the user's body is the highest, the second moment may represent the time point when the drug concentration in the user's body is the lowest, and the fifth graphical user interface may display a pattern for blood pressure calibration, for example, as described above. Figure 4 The "blood pressure" icon shown in (a) can also display the text of blood pressure calibration. In addition, the user can be prompted to perform the first operation through other methods of reminding the user to perform blood pressure calibration as mentioned above, which will not be repeated here. Among them, the drugs taken by the user can be antihypertensive drugs. As shown in Table 2 above, the time point when the drug concentration in the user's body is the highest and the time point when the drug concentration in the user's body is the lowest can be determined based on the type, dosage and time of taking the antihypertensive drugs taken by the user, and the user can be reminded to perform blood pressure calibration at these two time points; the specific implementation method can be referred to the above. Figure 11A 、 Figure 11B and Figure 12 Related statements in .

[0240] In this way, calibration is performed once when the user's drug concentration is highest and when the drug concentration is lowest, fully considering the impact of changes in drug concentration on the user's blood pressure, improving the accuracy of blood pressure calibration, and making the blood pressure values ​​measured by the calibrated wearable device more accurate.

[0241] In one possible implementation, the method may further include: displaying a fifth graphical user interface every preset period, the fifth graphical user interface being used to prompt the user to perform the first operation, or measuring the user's fourth blood pressure value through the airbag and the pressure sensor, and displaying the fifth graphical user interface when the difference between the fourth blood pressure value and the third blood pressure value corresponding to the most recently collected third physiological indicator information is greater than a first threshold.

[0242] In an embodiment of the present application, taking into account that the user's physical condition or the state of the user's environment will continue to change, a fifth graphical user interface can be displayed at preset intervals to prompt the user to perform the first operation, that is, reminding the user to calibrate the blood pressure of the wearable device, or, after obtaining the user's fourth blood pressure value through measurement by the airbag and pressure sensor configured by the wearable device (the measurement can be automatically triggered according to a preset period, or triggered when the user uses the wearable device to measure blood pressure), the fourth blood pressure value is compared with the third blood pressure value determined at the most recent time point before the time point of measuring the fourth blood pressure value (that is, the third blood pressure value corresponding to the most recently collected third physiological indicator information). When the difference between the two is greater than the first threshold, the fifth graphical user interface is displayed to remind the user to perform the first operation, that is, reminding the user to calibrate the blood pressure of the wearable device, thereby improving the accuracy of blood pressure measurement by the calibrated wearable device.

[0243] Among them, the preset period can be 1 day, 1 week, 1 month, etc., and the first threshold can be pre-set, and the embodiment of the present application does not limit this; the method of reminding the user to calibrate blood pressure can refer to the previous text and will not be repeated here.

[0244] Figure 19 A flow chart showing another blood pressure monitoring method according to an embodiment of the present application is shown. The method can be executed on an electronic device, for example, Figure 2 The scenario shown is executed on the wearable device, such as Figure 19 As shown, the method may include the following steps:

[0245] Step 2001: In response to a first operation, the electronic device enters a calibration mode;

[0246] Step 2002: Display a first graphical user interface; the first graphical user interface is used to prompt the user to perform a first action;

[0247] Step 2003: collecting first physiological indicator information;

[0248] Step 2004: displaying a second graphical user interface, wherein the second graphical user interface is used to prompt the user to input a first blood pressure value;

[0249] Step 2005: receiving a first blood pressure value input by a user;

[0250] Step 2006: Display a third graphical user interface; the third graphical user interface is used to prompt the user to perform a second action;

[0251] Step 2007: collecting second physiological indicator information;

[0252] Step 2008: displaying a fourth graphical user interface, wherein the fourth graphical user interface is used to prompt the user to input a second blood pressure value;

[0253] Step 2009: receiving a second blood pressure value input by the user;

[0254] Step 2010: In response to the second operation, the electronic device enters a measurement mode;

[0255] Step 2011: collecting third physiological indicator information;

[0256] Step 2012: Determine a third blood pressure value corresponding to the third physiological indicator information based on the first blood pressure value, the second blood pressure value, the first physiological indicator information, and the second physiological indicator information.

[0257] According to an embodiment of the present application, during the calibration phase, multiple graphical user interfaces (including a first graphical user interface and a third graphical user interface) are displayed to prompt the user to perform different actions (including a first action and a second action), thereby causing changes in the user's blood pressure influencing factors such as heart rate, stroke volume, and total peripheral resistance. Physiological indicator information (including first physiological indicator information and second physiological indicator information) is collected when the user performs different actions. Multiple graphical user interfaces (including a second graphical user interface and a fourth graphical user interface) are displayed to prompt the user to input blood pressure values ​​(including first blood pressure value and second blood pressure value), and the blood pressure values ​​input by the user are received, thereby fully capturing the changes in the user's blood pressure influencing factors and achieving blood pressure calibration in multiple calibration scenarios. During the measurement phase, based on the multiple blood pressure values ​​and multiple physiological indicator information obtained during the calibration phase, the blood pressure value (i.e., the third blood pressure value) corresponding to the collected physiological indicator information (i.e., the third physiological indicator information) is determined. The accuracy of this blood pressure value is higher, thereby achieving accurate measurement of the user's blood pressure.

[0258] The first operation, the second operation, the first action, the second action, the first physiological indicator information, the second physiological indicator information and the third physiological indicator information can refer to the above Figure 18 The first blood pressure value and the second blood pressure value can be measured by other devices (such as the blood pressure measuring instrument mentioned above), and the wearable device can be provided with an input component to receive the blood pressure value input by the user. In one example, Figure 2 The blood pressure measuring device measures the first blood pressure value when the user performs a first action, and the second blood pressure value when the user performs a second action; the wearable device itself is provided with an input component, which receives the first blood pressure value or the second blood pressure value displayed on the blood pressure measuring device input by the user. The first graphical user interface and the third graphical user interface can refer to the above. Figure 18 The second graphical user interface and the fourth graphical user interface can be as described above. Figure 16 (f) and Figure 17(c) shown.

[0259] Step 2001-step 2011, refer to the above Figure 15 Step 1801 and step 1802 are shown. Step 2012 can refer to Figure 15 Related examples or instructions in step 1803.

[0260] In one possible implementation, after the electronic device enters the calibration mode in response to the first operation, the method further includes: displaying a fifth graphical user interface, wherein the fifth graphical user interface displays multiple calibration scene options, and in response to the user selecting a calibration scene, the first graphical user interface is displayed. A detailed description of the fifth graphical user interface can be found in Figure 18 For an introduction to the third graphical user interface and detailed instructions for calibration scenarios, refer to the previous article. This allows users to select the most appropriate calibration scenario based on their daily activities, making calibration more personalized and targeted, effectively reducing calibration time and improving the user experience.

[0261] Illustratively, the calibration scenario corresponds to one or more of a calibration scenario for the user's physical condition and a calibration scenario for the state of the user's environment. Thus, in different calibration scenarios, the user's physical condition and the state of the user's environment vary, and accordingly, factors influencing the user's blood pressure, such as heart rate, stroke volume, and total peripheral resistance, vary. By inducing changes in the factors influencing the user's blood pressure based on the different physical conditions or environmental conditions of the user, the changes in the factors influencing the user's blood pressure are fully captured, enabling blood pressure calibration under different user physical conditions or environmental conditions.

[0262] For example, calibration scenarios corresponding to the user's physical state may include one or more of a sitting scene, a lying scene, a standing scene, a mental activity scene, a relaxation / resting scene, an anaerobic exercise scene, and an aerobic exercise scene. Calibration scenarios corresponding to the state of the user's environment may include one or more of a cold scene and a hot and humid scene. Detailed descriptions of each calibration scenario, etc., can be found above. Thus, in different scenarios, factors affecting the user's blood pressure, such as heart rate, stroke volume, and total peripheral resistance, change. The multiple calibration scenarios provided can more comprehensively cover the changes in factors affecting the user's blood pressure, thereby enabling blood pressure calibration in different scenarios and improving the accuracy of blood pressure measurement by the calibrated wearable device.

[0263] In a possible implementation, after displaying the first graphical user interface, the method further includes: displaying a sixth graphical user interface, wherein the sixth graphical user interface displays timing information. Detailed description of the sixth graphical user interface can be found in Figure 18For the relevant introduction of the fourth graphical user interface and the specific description of the timing information, please refer to the previous text. In this way, the timing information is displayed through the fourth graphical user interface to prompt the user of the time when the first action has been performed, or the time when the first action is still required. The user can complete the indicated exercise according to the prompts of the graphical user interface, thereby completing the blood pressure measurement in the corresponding calibration scenario, which is simple and convenient and improves the user experience.

[0264] In one possible implementation, in step 2012, the third blood pressure value corresponding to the third physiological indicator information is determined based on the first blood pressure value, the second blood pressure value, the first physiological indicator information and the second physiological indicator information, including: determining the similarity between the first physiological indicator information and the third physiological indicator information, and the similarity between the second physiological indicator information and the third physiological indicator information; determining the target similarity greater than the second threshold value, and the target physiological indicator information corresponding to the target similarity; performing weighted summation on the target blood pressure values ​​corresponding to the target physiological indicator information to obtain the third blood pressure value, wherein the weight of the target blood pressure value is positively correlated with the similarity between the corresponding target physiological indicator information and the third physiological indicator information. This step can refer to the above Figure 18 In this way, one or more target blood pressure values ​​obtained during the calibration phase that are most similar to the current measurement scenario are selected, and these blood pressure values ​​are weighted and summed to predict the third blood pressure value currently being measured. The weight of each target blood pressure value is positively correlated with the similarity between the corresponding target physiological indicator information and the third physiological indicator information; that is, the higher the similarity, the greater the weight of the corresponding first target blood pressure value, thereby increasing the blood pressure measurement range and improving the accuracy of blood pressure measurement.

[0265] In a possible implementation, the method may further include: obtaining the type, dosage, and time of medication taken by the user; determining a first moment and a second moment based on the type, dosage, and time of medication; and displaying a seventh graphical user interface at the first moment and the second moment, respectively, the seventh graphical user interface being used to prompt the user to perform the first operation. The detailed description of the seventh graphical user interface may refer to the above Figure 18 The first moment can represent the time when the drug concentration in the user's body is the highest, and the second moment can represent the time when the drug concentration in the user's body is the lowest. In this way, calibration is performed at the time when the drug concentration is the highest and lowest, respectively. This fully considers the impact of changes in drug concentration on the user's blood pressure, improves the accuracy of blood pressure calibration, and thus makes the blood pressure values ​​measured by the calibrated wearable device more accurate.

[0266] In one possible implementation, the method may further include: displaying a seventh graphical user interface at a preset interval, the seventh graphical user interface being used to prompt the user to perform the first operation. The preset interval may refer to the aforementioned description. Thus, considering that the user's physical condition or the state of the user's environment may constantly change, the seventh graphical user interface may be displayed at a preset interval to prompt the user to perform the first operation, i.e., to remind the user to calibrate the wearable device's blood pressure, thereby improving the accuracy of blood pressure measurement by the calibrated wearable device.

[0276] According to an embodiment of the present application, during the calibration phase, multiple graphical user interfaces are displayed to prompt the user to perform different actions, thereby causing changes in the user's blood pressure influencing factors such as heart rate, stroke volume, and total peripheral resistance. Blood pressure values ​​sent by other devices when the user performs different actions are received, and physiological indicator information is collected, fully capturing the changes in the user's blood pressure influencing factors and achieving blood pressure calibration in multiple calibration scenarios. During the measurement phase, based on the multiple blood pressure values ​​and multiple physiological indicator information obtained during the calibration phase, a third blood pressure value corresponding to the collected third physiological indicator information is determined. This blood pressure value has higher accuracy, thereby achieving accurate measurement of the user's blood pressure.
