Description

Blood pressure monitoring method and device and wearable equipment

Technical Field

The application relates to the technical field of intelligent terminals, in particular to a blood pressure monitoring method and device and wearable equipment.

Background

The prevalence of Cardiovascular Disease (CVD) in china is in a continuously rising stage. At present, the number of sick people in China is 2.9 hundred million, and about 350 million people die of cardiovascular diseases every year. The cardiovascular disease mortality is the top, higher than that of tumors and other diseases. In every 10 ten thousand rural or urban residents, the number of heart disease deaths reaches 143.72 and 136.21 respectively, and the health of people in China is seriously threatened. Hypertension is the first risk factor of cardiovascular and cerebrovascular diseases, and about 2.7 hundred million hypertension patients occur in China. The research result of Chinese hypertension research (CHS) in 2012-2015 shows that the prevalence rate of hypertension of Chinese adults is 27.9%, and the prevalence rate of hypertension of residents aged more than or equal to 15 years is in an ascending trend; however, the known rate of hypertension in China is about 51.5%, the medicine taking rate is about 46.1%, and the control rate is about 16.9%, which are far lower than 86.2%, 73% and 61% of the United states.

Continuous blood pressure monitoring is a major innovation in the development history of hypertension diagnosis technology, and can be used for measuring the blood pressure of a person in daily life, not only the blood pressure in light and medium physical activity states, but also the blood pressure in the sleeping process. The continuous blood pressure monitoring has the advantages of removing measurement contingency, reducing misdiagnosis rate, identifying hidden night hypertension, identifying white overcoat hypertension, measuring blood pressure rhythm, guiding medication and the like.

In the existing blood pressure measuring methods, the methods such as an auscultation method, an oscillography and the like all need to manually or automatically inflate and deflate the cuff to assist in measurement, so that the measuring method causes discomfort to a user, and only one blood pressure value can be measured within a period of time, and continuous measurement cannot be carried out. The noninvasive cuff-free blood pressure measurement method (such as a pulse wave feature parameter method and a pulse wave velocity blood pressure measurement method) can realize continuous blood pressure monitoring, and blood pressure measurement models established by different subjects are easily influenced by individual differences, so that in order to reduce the influence of the individual differences on blood pressure prediction results, blood pressure calibration is usually carried out by means of cuff blood pressure, and the continuous change of the blood pressure is monitored on the basis of calibration values.

However, the existing blood pressure calibration method for continuous blood pressure monitoring equipment by using the blood pressure with the cuff has poor calibration effect, and the blood pressure measurement precision after calibration needs to be improved.

In the drawings, like reference numbers can indicate functionally identical or similar elements. While the various aspects of the embodiments are presented in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.

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

Furthermore, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present application. It will be understood by those skilled in the art that the present application may be practiced without some of these specific details. In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present application.

Hypertension is the most common chronic non-infectious disease and the most heavily burdened disease worldwide. Hypertension is associated with a range of clinical conditions and adverse consequences and has become a significant public health problem. The mechanism of occurrence of hypertensive cardiovascular and cerebrovascular events varies by species. The population of the world is large, aging is aggravated, and reasonable diagnosis and treatment of hypertension are very important. Continuous blood pressure monitoring methods represented by the Ambulatory Blood Pressure Monitoring (ABPM) are important extra-office blood pressure measurement methods, and play a central role in hypertension monitoring and management; ABPM plays an important role in finding occult hypertension, abnormal blood pressure variation, abnormal blood pressure rhythm and the like.

The mobile medical technology represented by intelligent wearable equipment is developed rapidly recently, and blood pressure measurement technology based on the wearable equipment is particularly important. Due to the change of the measurement position and the measurement principle, generally speaking, the accuracy of the blood pressure measured based on the intelligent wearable device is lower than the accuracy of the blood pressure measured based on the auscultation method and the oscillography, and when the intelligent wearable device is used for continuous blood pressure monitoring, the blood pressure measurement precision needs to be improved through calibration.

Some related technologies for calibrating blood pressure by using the intelligent wearable device are briefly introduced below.

In some related techniques, multiple sets of data of a user in a scene are acquired, each set of data including pulse wave transit time and blood pressure value; from the plurality of sets of data, a set of parameters for measuring blood pressure using the blood pressure monitor is determined. In this example, the scene is single, the blood pressure influence factor has limited variation, and relatively accurate blood pressure values are not used as a reference, so the effects of blood pressure calibration and blood pressure tracking are poor.

In other related art, a sphygmomanometer cuff may be placed on an upper arm, and a wristwatch to be calibrated may be worn on a wrist of another arm. The mobile phone is placed on a desk and is convenient to take. On the mobile phone, opening a relevant application program and executing the following operations according to the description on the screen: blood pressure measurements are started on the cuff-based blood pressure monitor. The measurement on the watch to be calibrated will start automatically. Cuff-based blood pressure monitoring readings are entered in a mobile phone blood pressure monitoring application. The above procedure is repeated twice (three measurements in total) to complete the calibration of the watch to be calibrated. In the related technology, calibration is performed only in a sitting scene, and the blood pressure value measured in the using process slightly fluctuates near the calibration value, so that the blood pressure great change cannot be tracked. The reason is that only a single sitting scene is used in the calibration process, the state of the blood pressure influencing factors of the user cannot be induced to change, and the states of the blood pressure influencing factors are various when the user actually measures the blood pressure, so that the blood pressure measurement value is inaccurate in the blood pressure measurement process, and the change of the blood pressure cannot be tracked.

In order to solve the technical problem of poor blood pressure calibration effect, the embodiment of the application provides a blood pressure monitoring method, which can be executed by a blood pressure monitoring device and prompts a user to complete physical activities conforming to a plurality of calibration scenes through prompt information; after the user completes physical activities of different calibration scenes, the blood pressure influencing factors of the user, such as heart rate, stroke volume, total peripheral resistance and the like, are changed. In the blood pressure calibration stage, the calibration blood pressure value and the corresponding physiological signal of the user under each calibration scene are obtained, the change of blood pressure influence factors of the user is fully captured, and the blood pressure calibration under a plurality of calibration scenes is realized; in the blood pressure measuring stage, the blood pressure value of the user to be measured is determined according to the acquired physiological signals, the calibration blood pressure value and the corresponding physiological signals under the calibration scenes, the precision of the blood pressure value is higher, and therefore the accurate measurement of the blood pressure of the user is achieved.

The blood pressure monitoring device can be a device which has the function of measuring the blood pressure of a user and can improve the accuracy of blood pressure measurement through calibration. The blood pressure monitoring device may include an Electrocardiogram (ECG) sensor, a photoplethysmogram (PPG) sensor, a pressure sensor, a Ballistocardiograph (BCG) sensor, a Seismogram (SCG) sensor, an Impedance Plethysmogram (IPG) sensor, and other sensors capable of acquiring physiological signals of a user, and the sensors may measure the physiological signals of the user such as PPG, ECG, IPG, SCG, BCG, heart sounds, and determine corresponding physiological index information to obtain a blood pressure value of the user.

For example, the blood pressure monitoring device may be a smart wearable device having a blood pressure monitoring function, which may be a device worn on an arm or a wrist, for example, a smart wearable watch or the like; but also devices worn on the chest or palm, such as smart necklaces and the like; but also devices worn on the head, e.g. smart headsets, etc.; the specific form of the intelligent wearable device is not limited by the application. Illustratively, the blood pressure monitoring device may be a professional device in a hospital with blood pressure monitoring function, e.g., a 24-hour ambulatory blood pressure meter; illustratively, the blood pressure monitoring device can also be an intelligent body fat scale, a blood pressure measuring instrument and other devices with a blood pressure monitoring function.

In the embodiment of the application, the blood pressure monitoring method provided by the application is described by taking the blood pressure monitoring device as an example of an intelligent wearable watch.

FIG. 1 illustrates a schematic diagram of an application scenario according to an embodiment of the present application; as shown in fig. 1, when calibrating blood pressure, the user wears the smart wearable watch 101 on the left hand or the right hand (the smart wearable watch 101 is worn on the right wrist in the figure), and in order to achieve a better blood pressure measurement effect, the user can attach the watchband of the smart wearable watch 101 to the wrist.

In some examples, smart wearable watch 101 may include: air bags (such as micro pump air bags), pressure sensors and PPG sensors, or ECG sensors; wherein, gasbag and pressure sensor cooperation work measure user's blood pressure value through the oscillography, regard this blood pressure value as calibration blood pressure value, and the measurement process can include: the micro pump is used for pressurizing to automatically inflate the air bag, the pressurization is stopped after the air bag is inflated for a certain time, the air bag starts to deflate, when the air pressure is reduced to a certain degree, blood flow can pass through the blood vessel, certain oscillation waves are provided, the oscillation waves are transmitted to the pressure sensor, the pressure sensor can detect the pressure and the fluctuation in the air bag in real time, then the blood pressure value of a user is measured and calculated based on the pressure and the fluctuation and based on the oscillography principle, and the blood pressure value is the calibration blood pressure value.

Wherein, the PPG sensor is used for gathering PPG signal, and the acquisition process includes: the light emitting diode of the PPG sensor emits a photoelectric signal to the skin of a user, and the pulse wave is collected through the photosensitive diode of the PPG sensor to generate a PPG signal. An ECG sensor may be used to acquire ECG signals. In the related technology, a blood pressure value can be obtained through a pulse wave characteristic parameter measurement method according to the corresponding relation between the characteristic value of the preset characteristic of the PPG signal and the blood pressure value; the measurement principle is based on the corresponding relation between different feature values of the preset feature of the PPG signal and the blood pressure value, which is established in advance, and after the feature value of the preset feature of the PPG signal which is actually measured is calculated, the blood pressure value corresponding to the feature value is determined according to the corresponding relation, namely the blood pressure value of the user. Or the PPG sensor and the ECG sensor can be used in a matching way, and the blood pressure value of the user can be measured by a pulse wave velocity blood pressure measuring method; the measurement principle is based on the positive correlation between the Velocity of Pulse Wave (PWV) and the arterial blood pressure, which is the Velocity of the Pulse propagating along the artery; a commonly used PWV measurement method may include calculating Pulse Transit Time (PTT), i.e. the Time required for a Pulse wave to travel from the heart to a point on the artery, and specifically includes: synchronously acquiring an ECG signal and a PPG signal, and identifying the maximum value point of the R wave of the ECG signal and the PPG signal to obtain delay time PTT; the blood pressure values of the systolic pressure and the diastolic pressure are finally obtained through a preset mathematical model relation (for example, a linear function relation between the PTT and the blood pressure) between the PTT and the blood pressure.

It should be noted that the pulse wave characteristic parameter method and the pulse wave velocity blood pressure measurement method are only examples, and in the related art, the blood pressure value of the user may also be obtained by other non-invasive cuff-less blood pressure measurement methods, for example, the pulse wave velocity blood pressure measurement method may also be combined with the pulse wave characteristic parameter method to obtain the blood pressure value.

In this scene, for obtaining compare in the blood pressure value that the blood pressure value precision is higher based on the PPG signal, or the PPG signal combines together with the ECG signal and obtains, intelligence is dressed the wrist-watch and is passed through gasbag, pressure sensor and obtain the blood pressure value of calibrating, combines the physiological signal that calibration blood pressure value and PPG sensor (or PPG sensor, ECG sensor etc.) obtained again, obtains the blood pressure value of higher accuracy, need not to rely on other equipment and can accomplish the blood pressure calibration, convenient and fast.

FIG. 2 illustrates another application scenario diagram according to an embodiment of the present application; as shown in fig. 2, 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 smart wearable watch 101 is worn on the right wrist and the blood pressure monitor 102 is worn on the left arm in the figure), and can also wear the smart wearable watch 101 and the blood pressure monitor 102 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 tightly attach the watchband of the smart wearable watch 101 to the wrist and tightly attach the cuff of the blood pressure monitor 102 to the arm. Illustratively, the smart wearable watch 101 and the blood pressure monitor 102 may be connected in a wired or wireless (e.g., bluetooth, wifi, etc.) manner.

The blood pressure monitor 102 may be a blood pressure monitor that passes medical authentication, and the blood pressure monitor 102 may measure the blood pressure value of the user through an oscillometric method.

In some examples, smart wearable watch 101 may include: a PPG sensor, or may also include an ECG sensor. The working principle of PPG and ECG sensors can be seen above.

In this scene, for obtaining compare in based on the higher blood pressure value of the blood pressure value precision that PPG signal, perhaps PPG signal and ECG signal combined together obtained, intelligence is dressed the wrist-watch and can be measured through blood pressure monitor and calibrate blood pressure value, and the physiological signal that combines calibration blood pressure value and PPG sensor (or PPG sensor, ECG sensor etc.) to obtain the blood pressure value of higher accuracy, further promotes calibration accuracy.

It should be noted that the foregoing application scenarios described in the embodiments of the present application are for more clearly illustrating the technical solutions in the embodiments of the present application, and do not constitute limitations on the technical solutions provided in the embodiments of the present application, and a person having ordinary skill in the art can know that the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems for the occurrence of other similar or new application scenarios.

The blood pressure monitoring method provided by the present application is described below with reference to the application scenario shown in fig. 1.

Fig. 3 shows a flow chart of a blood pressure monitoring method according to an embodiment of the present application, which may include the following steps, as shown in fig. 3:

step 301, the smart wearable watch responds to a user instruction and enters a calibration mode.

In this step, when blood pressure calibration needs to be performed on the intelligent wearable watch 101 in fig. 1, a user may trigger an instruction to enter a calibration mode, and the intelligent wearable watch enters the calibration mode in response to the instruction; illustratively, a user may trigger an instruction to enter a calibration mode by clicking a virtual key of the calibration mode on a display screen of the smart wearable watch; exemplarily, the user may further trigger the instruction to enter the calibration mode by pressing a physical button provided by the smart wearable watch for entering the calibration mode; illustratively, the user can also trigger an instruction for entering the calibration mode by means of a voice instruction; illustratively, the user can also trigger an instruction for entering the calibration mode in a shortcut gesture mode; in practical applications, the user may also trigger the instruction to enter the calibration mode through other manners, which is not limited in this embodiment of the application.

For example, fig. 4 shows a schematic diagram of a smart wearable watch entering a calibration mode according to an embodiment of the present application. As shown in fig. 4(a), a user may click an icon of a "blood pressure" application program of the smart wearable watch to trigger the smart wearable watch 101 to perform the application program, and as shown in fig. 4(b), a virtual key 401 in a calibration mode and a virtual key 402 in a measurement mode are displayed on a display screen of the smart wearable watch 101; the user can trigger an instruction to enter the calibration mode by clicking the virtual key 401 of the calibration mode, and the smart wearable watch 101 enters the calibration mode in response to the instruction.

Step 302, the intelligent wearable watch measures a calibration blood pressure value of the user in each of different calibration scenes, and collects physiological signals of the user.

In the step, according to different preset calibration scenes, the intelligent wearable watch collects physiological signals of the user in different calibration scenes. Wherein the physiological signal may include: pulse wave signals, electrocardiosignals and the like, wherein the electrocardiosignals are sent out when the heart of the user beats, such as ECG signals and the like; the pulse wave signal is formed by interaction between blood flowing in a blood vessel and the blood vessel, for example, a PPG signal and the like. Simultaneously, the gasbag and the pressure sensor cooperation work of wrist-watch are dressed to intelligence, measure user's blood pressure value through the oscillography, as calibration blood pressure value.

In a possible implementation, the smart wearable watch measures a calibrated blood pressure value of the user and collects a physiological signal of the user in each calibration scenario, and may include: the intelligent wearable watch can measure a calibration blood pressure value under the calibration scene through an oscillography, and collects physiological signals of a user under the scene; the time for measuring the calibration blood pressure value in the calibration scene may be before the time for acquiring the physiological signal in the scene of the user, or after the time for acquiring the physiological signal in the scene of the user, for example, after the calibration blood pressure value in the scene is obtained by an oscillography, the physiological signal in the calibration scene of the user starts to be acquired at a certain interval, so as to avoid the influence of the air pressure change on the physiological signal; for example, the air bag and the pressure sensor of the intelligent wearable watch cooperate to obtain a calibrated blood pressure value under the calibration scene, after an interval of 30S, the PPG sensor of the intelligent wearable watch starts to work to acquire the PPG signal of the user, or the PPG sensor and the ECG sensor of the intelligent wearable watch start to work to acquire the PPG signal and the ECG signal of the user.

The change of the blood pressure is brought under different environments of different positions, postures, sports, diets, medicines, time, seasons, environments and the like of a human. The Blood pressure changes are realized by changing the Cardiac Output (CO), Total Peripheral Resistance (TPR) and other factors of a human, the CO is influenced by the Heart Rate (HR) and Stroke Volume (Stroke Volume), the TPR is influenced by Arteriolar Radius (AR) and Blood viscosity (Blood viscosity), and the Heart Rate, Stroke Volume, arteriolar diameter and Blood viscosity can be influenced by other factors. Therefore, in the embodiment of the application, the calibration scene may be a preset scene, and in different scenes, the body state of the user or the state of the environment where the user is located are different, so that the change of the body state of the user or the state of the environment where the user is located is induced through the design scene, the blood pressure influence factors such as heart rate, heart stroke volume, total peripheral resistance and the like are changed in different body states or the state of the environment where the user is located, the blood pressure calibration is performed in various body states or the state of the environment where the user is located, the physiological signals and the calibration blood pressure value of the user in different body states or the state of the environment where the user is located are obtained, the change of the blood pressure influence factors of the user is fully captured, and the accurate tracking of the blood pressure of the user can be realized by using the calibrated device.

Illustratively, table 1 shows several preset calibration scenarios; as shown in table 1, the calibration scenario may include: a sedentary scene, a recumbent scene, a standing scene, a mental activity scene, a relaxation/rest scene, an anaerobic exercise scene, an aerobic exercise scene, a cold scene, a smoldering scene, and the like.

The sitting scene, the lying scene and the standing scene are scenes in a quiet state, and the scenes represent changes of the body state of the user in different postures. For example, a sedentary scenario may include a user's sedentary activities, characterizing the physical state in a sedentary posture; the sleeping scene can comprise the sleeping activity of the user and represents the body state in the sleeping posture; a standing scenario may include a user stationary standing activity, characterizing the physical state in a standing posture.

Wherein, the mental activity scene and the relaxation/rest scene are scenes under the neural activity, and the scenes represent the change of the physical state of the user when the sympathetic nerve and/or the parasympathetic nerve are excited to different degrees. For example, mental activity scenarios may include: doing activities such as mathematic questions and question-answering questions, representing the physical state of sympathetic nerve excitation, stimulating the rise of heart rate and heart stroke volume, contracting veins to increase venous return, contracting arteries to increase peripheral resistance and raising blood pressure; the relaxation/rest scenario may include activities such as the valsalva (Vasalva) test, physical states that characterize parasympathetic excitation, stimulate a reduction in heart rate, and lower blood pressure.

Among them, the anaerobic exercise scene and the aerobic exercise scene are scenes under exercise, and these scenes represent the change of the body state of the user during the aerobic exercise and/or the anaerobic exercise. For example, an anaerobic exercise scenario may include a physical state of a campstool-like activity, characterizing an increase in heart rate, an increase in cardiac output, an increase in peripheral resistance, and a rapid rise in blood pressure. Aerobic exercise scenes can include activities such as cycling, bench tests, etc., characterizing physical states that increase heart rate, increase cardiac output, reduce peripheral resistance, and raise blood pressure.

The cold scene and the sultry scene are temperature-related scenes, and represent changes of the state of the environment where the user is located. For example, a cold scene may include cold water stimulation, etc. activity, where the user is in the environment, peripheral vasoconstriction, increased peripheral resistance, elevated blood pressure; the muggy scenario may include hot water stimulation and other activities, where the user is in the environment, peripheral vasodilation, reduction of peripheral resistance, and lowering of blood pressure.

TABLE 1 calibration scenarios Table

The process of completing blood pressure calibration by a user through an intelligent wearable watch in different calibration scenes is explained below by taking a sitting scene, a sleeping scene, a mental activity scene, a relaxation/rest scene and an anaerobic exercise scene as examples.

FIG. 5 shows a schematic diagram of blood pressure calibration under multiple calibration scenarios, according to an embodiment of the present application; the intelligent wearable watch provides prompt information aiming at a sitting scene, a lying scene, a mental activity scene and a relaxation/rest scene, so that a user is prompted to complete physical activities according with various calibration scenes; after the blood pressure calibration in a calibration scene begins, the body activity aiming at the calibration scene can be prompted on a display screen of the intelligent wearable watch, so that the body activity required to be completed by a user in the calibration scene is prompted to the user; for example, as shown in fig. 5(a1), after the blood pressure calibration in the resting scene is started, the word "please rest for 1 minute" is displayed on the display screen, so as to remind the user that the user needs to keep the resting posture for 1 minute in the calibration scene; as shown in fig. 5(a2), after the blood pressure calibration in the sedentary scene is started, the word "please sit still for 1 minute" is displayed on the display screen, thereby reminding the user of maintaining the sedentary posture for 1 minute; as shown in fig. 5(a3), after the blood pressure calibration in the mental activity scene is started, the display screen may display a minute of mathematical operation performed by the user according to a certain rule or a question and answer question to the user, for example, a word "please perform a calculation of subtracting 7 from 500 continuously for one minute" may be displayed, so as to remind the user that the calculation of subtracting 7 from 500 continuously (i.e. 500-7-493,493-7-486 … …) is required for one minute; as shown in fig. 5(a4), after the blood pressure calibration in the relaxation/rest scene begins, the words "valsalval is active for one minute (please inhale and then close the mouth and nose and exhale 5 times)" are displayed on the display screen, so as to remind the user that the valsalval is active for one minute, specifically, the mouth and nose should be closed and then exhale 5 times within one minute; after prompting the user about the physical activity to be completed in a calibration scene, as shown in fig. 5(b), a word "countdown is about to start" is displayed on the display screen of the smart wearable watch, so as to prompt the user to prepare for the physical activity according with the calibration scene, for example, prepare for keeping a lying posture for 1 minute, prepare for keeping a sitting posture for 1 minute, prepare for mathematical operation for one minute, and prepare for performing valsalval activity for one minute; as shown in fig. 5(c), a "countdown" word may be displayed on the display screen of the smart wearable watch, a countdown time may be displayed, and dynamic patterns such as "hourglass" and "progress bar" may also be displayed, so as to remind the user to continue to perform the physical activity conforming to the calibration scene, and also remind the user of a time at which the physical activity conforming to the calibration scene needs to be performed, in addition, the smart wearable watch may remind the user of continuing to perform the physical activity conforming to the calibration scene in a language broadcasting manner, and also remind the user of a time at which the physical activity conforming to the calibration scene needs to be performed; as shown in fig. 5(d), after the countdown is finished, a word "please keep still" in the blood pressure measurement is displayed on the display screen of the smart wearable watch, so as to remind the user to keep still, and in addition, the smart wearable watch can remind the user to keep still in a voice broadcast mode; for example, in a sleeping scene, the user can be reminded to keep the sleeping position still, and in a sitting scene, a mental activity scene and a relaxation/rest scene, the user can be reminded to keep the sitting position still; at the moment, the air bag and the pressure sensor of the intelligent wearable watch cooperate to measure the blood pressure of the user, and the PPG sensor (or the PPG sensor and the ECG sensor) of the intelligent wearable watch collects physiological signals of the user. As shown in fig. 5(e), the display screen of the watch is worn to intelligence shows "measurement finishes" word to remind the user that a blood pressure measurement under this calibration scene finishes, in addition, the watch is worn to intelligence can also remind the user that a blood pressure measurement under this calibration scene finishes with the form that the language was reported.

FIG. 6 illustrates a schematic diagram of blood pressure calibration in an anaerobic motion scenario, in accordance with an embodiment of the present application; the intelligent wearable watch provides prompt information aiming at the anaerobic exercise scene, so that a user is prompted to complete physical activities according with the anaerobic exercise scene; after the blood pressure calibration is started in an anaerobic exercise scene, the processes in fig. 6(a) -6(c) are sequentially executed, as shown in fig. 6(a), a display screen of the intelligent wearable watch displays that the user needs to perform the steps of jumping to the limit, then the user sits down and clicks a character for starting measurement and a virtual button for starting, so that the user is reminded that the user needs to perform the steps of jumping to the limit in the calibration scene, then the user sits down and clicks to start measurement, in addition, the intelligent wearable watch can remind the user that the user needs to perform the steps of jumping to the limit in a language broadcasting mode, then the user sits down and clicks to start measurement, and the intelligent wearable watch can also perform demonstration guidance of jumping to the limit to the user in the modes of voice, pictures, videos and the like; the user clicks the start button to trigger a blood pressure measurement start instruction on the premise that the user steps to the limit and keeps sitting, the intelligent wearable watch responds to the instruction to start blood pressure measurement, as shown in fig. 6(b), a word "please keep still in blood pressure measurement" is displayed on a display screen of the intelligent wearable watch, and therefore the user is reminded of keeping still, and in addition, the intelligent wearable watch can remind the user of keeping sitting still in a language broadcasting mode; at this moment, the air bag and the pressure sensor of the intelligent wearable watch cooperate to measure the calibration blood pressure value of the user, and the PPG sensor (or the PPG sensor and the ECG sensor) of the intelligent wearable watch acquires the physiological signal of the user. As shown in fig. 6(c), the word "finish measuring" is shown on the display screen of wrist-watch is dressed to intelligence to remind the blood pressure measurement that the user was under the anaerobic exercise scene to finish, in addition, the wrist-watch is dressed to intelligence can also remind the blood pressure measurement that the user was under the anaerobic exercise scene to finish with the form that the language was reported.

In one possible implementation, the smart wearable watch may measure a calibrated blood pressure value of the user in each calibration scenario under a standard scenario, and collect a physiological signal of the user.

For example, FIG. 7 shows a schematic diagram of a calibration scenario selection according to an embodiment of the present application; as shown in fig. 7, the user clicks the calibration mode virtual button 401 in fig. 7(a), to trigger the smart wearable watch 101 to enter the calibration mode, and in the calibration mode shown in fig. 7(b), a virtual key 1001 in a standard scene and a virtual key 1002 in a custom scene are displayed on the display screen of the smart wearable watch 101; the user can trigger an instruction for blood pressure calibration in the standard scene by clicking the virtual key 1001 of the standard scene, and the intelligent wearable watch 101 responds to the instruction to execute a blood pressure calibration process in the standard scene.

The standard scenario may include a fixed combination of the preset multiple calibration scenarios, and each calibration scenario has a fixed execution order, and for example, the standard scenario may include: and sequentially executing a sitting scene, a lying scene, a mental activity scene, a relaxation/rest scene and an anaerobic exercise scene. It should be noted that the type and number of calibration scenes included in the standard scene and the execution sequence of each calibration scene may be set according to requirements, which is not limited in the embodiment of the present application.

Therefore, the user can complete blood pressure calibration in the standard scene by triggering the blood pressure calibration flow in the standard scene of the intelligent wearable device, and the blood pressure calibration flow can be obtained by combining the analysis of the blood pressure influence factors, so that the standard scene covers a plurality of calibration scenes in which the blood pressure influence factors such as heart rate, heart stroke volume and total peripheral resistance can be induced to change. The user need not to carry out other setting operations, can accomplish the blood pressure calibration under the standard scene, and easy operation is convenient, and calibrates effectually. For example, when a user uses the intelligent wearable watch to calibrate blood pressure for the first time, a standard scene can be selected, the calibration of the blood pressure is completed in the standard scene, the characteristics of blood pressure influence factors of the user can be acquired through one-time calibration, and then the prediction of the blood pressure value in the subsequent measurement stage is ensured to be more accurate.

FIG. 8 illustrates a flow chart of blood pressure calibration in a standard scenario according to an embodiment of the present application; as shown in fig. 8, after the blood pressure calibration in the standard scene is started, the smart wearable watch may sequentially perform step 1101, the blood pressure calibration in the recumbent scene, step 1102, the blood pressure calibration in the sitting scene, step 1103, the blood pressure calibration in the mental activity scene, step 1104, the blood pressure calibration in the relaxation/rest scene, and step 1105, the blood pressure calibration in the anaerobic exercise scene; thereby completing the blood pressure calibration in the standard scene. The embodiment of the present application does not limit the execution order of these steps.

For example, the smart wearable watch may sequentially complete the blood pressure calibration in the recumbent scene, the sedentary scene, the mental activity scene, the relaxation/rest scene, and the anaerobic exercise scene by executing the processes in fig. 5 and fig. 6, and thus complete the blood pressure calibration process in the standard scene.

In a possible implementation manner, the smart wearable watch can measure the calibration blood pressure value of the user in each calibration scene in the user-defined scene, and acquire the physiological signal of the user.

Wherein, the self-defined scene can include a plurality of calibration scenes of the aforesaid presetting, and the execution order of every calibration scene, calibration scene category, quantity that the self-defined scene includes, and the execution order of each calibration scene can be set for by the user, exemplarily, the user can select a plurality of calibration scenes in a plurality of candidate calibration scenes of presetting, and regard the precedence order of each calibration scene of presetting as the execution order of each calibration scene, if the user has selected the sedentary scene in proper order, the sedentary scene, mental activity scene, relax/rest scene, anaerobic motion scene, then the self-defined scene can include: a sitting scene, a lying scene, a mental activity scene, a relaxation/rest scene and an anaerobic exercise scene are sequentially executed.

For example, as shown in fig. 7, after the smart wearable watch 101 enters the calibration mode, the user may trigger an instruction for performing blood pressure calibration in a user-defined scene by clicking a virtual key 1002 in the user-defined scene, and the smart wearable watch 101 executes a blood pressure calibration process in the user-defined scene in response to the instruction.

The user-defined scene may be a selected calibration scene from a plurality of calibration scenes provided by the smart wearable watch, for example, fig. 9 shows a schematic diagram for setting the user-defined scene according to an embodiment of the present application, a user may enter a user-defined selection page in fig. 9(b) by clicking a virtual button 1002 of the user-defined scene in fig. 9(a), at this time, the user may be presented with the selectable calibration scene on a display screen of the smart wearable watch, the calibration scene may include a plurality of calibration scenes shown in table 1 (only a sitting scene, a lying scene, and a mental activity scene are shown in the figure), and the user may select the user-defined scene by sliding up and down, clicking the virtual button, and the like according to a habit of daily activities of the user. In this way, the user selects the calibration scenario according to the daily activities with the highest frequency, for example, if the user works in front of a computer, the sedentary scenario and the mental activity scenario can be selected as the custom scenario. Therefore, the user can select the most suitable and matched calibration scene to finish calibration according to daily activities of the user, so that the calibration is more personalized and more specific, the calibration time is effectively reduced, and the user experience is improved.

FIG. 10 illustrates a flow chart of blood pressure calibration in a custom scenario according to an embodiment of the present application; as shown in fig. 10, if the user-defined scene includes: the method comprises the steps that a sitting scene, a lying scene, a mental activity scene and an anaerobic movement scene are sequentially executed, after blood pressure calibration in a user-defined scene begins, the intelligent wearable watch can sequentially execute the step 1301, the blood pressure calibration in the lying scene, the step 1302, the blood pressure calibration in the sitting scene, the step 1303, the blood pressure calibration in the mental activity scene and the step 1304, the blood pressure calibration in the anaerobic movement scene; thereby completing the blood pressure calibration in the user-defined scene.

For example, the smart wearable watch may sequentially complete the blood pressure calibration in the recumbent scene, the sedentary scene, the mental activity scene and the anaerobic exercise scene by executing the above-mentioned flow in fig. 5(a1)/5(a2)/5(a3) -5(e) and the flow in fig. 6, and thus complete the blood pressure calibration flow in the user-defined scene.

In one possible implementation, the smart wearable watch may determine the blood pressure calibration time according to the user attribute.

Wherein the user attributes may include: the user is a hypertension medicine taking person or other persons. The blood pressure calibration time may be: the time for performing blood pressure calibration for each calibration scenario may also be the calibration time for the standard scenario or the custom scenario.

11A-11B illustrate an exemplary method of determining user attributes according to an embodiment of the present application; as shown in fig. 11A, (a) in fig. 11A, the user clicks the calibration mode virtual button 401 to trigger the smart wearable watch 101 to enter the calibration mode, and in fig. 11A, (b) the display screen of the smart wearable watch 101 displays the virtual button 1401 of the person taking the medicine for hypertension and the virtual buttons 1402 of other persons; the user can trigger the instruction of blood pressure calibration for the hypertension person taking medicine by clicking the virtual key 1401 of the hypertension person taking medicine, and the intelligent wearable watch 101 responds to the instruction and executes the blood pressure calibration process for the hypertension person taking medicine. If the user clicks the virtual key 1402 of another person, the smart wearable watch 101 executes the blood pressure calibration process in the standard scenario or the blood pressure calibration process in the user-defined scenario.

It should be noted that, the operation of selecting whether the person taking the medicine is the person taking the medicine for hypertension in fig. 11A and fig. 11B is not sequential to the operation of selecting the standard scene or the custom scene by the user in fig. 8, that is, the user may first select the standard scene or the custom scene, and then further select whether the user is the person taking the medicine for hypertension, as shown in fig. 11B; or whether the patient is a hypertension medicine-taking person or not can be selected firstly, and then a standard scene or a custom scene is further selected, as shown in fig. 11A.

In a possible implementation, in case the user is a hypertensive medicament provider, a blood pressure calibration may be performed at the time point in the user where the hypertensive medicament concentration is highest and the medicament concentration is lowest, respectively. Therefore, aiming at the hypertension dosing population, calibration is respectively carried out when the drug concentration is highest and the drug concentration is lowest, so that the influence of the change of the drug concentration on the blood pressure of a user is considered, and the measured blood pressure value is more accurate.

Wherein, the time points of the highest drug concentration and the lowest drug concentration can be determined according to the product instruction of the antihypertensive drug taken by the user or according to the related public data. As shown in table 2, examples are illustrated for the time at which the partial hypotensive drug concentration reached a peak.

Table 2: description of the time when the concentration of part of hypertension-lowering drugs reaches the peak value

Illustratively, the user may click the virtual key 1401 of each of the hypertension pill takers in fig. 11A and 11B, and select the virtual key according to the prompt information displayed on the display screen of the smart wearable watch or the voice prompt information, where the prompt information may include options of different types, different dosages, and different pill taking times of the hypertension pills, the user may select the type, the dosage, and the pill taking time of the hypertension pill to be taken, and the smart wearable watch may determine, according to the type and the dosage of the hypertension pill, a time point at which the concentration of the hypertension pill reaches the highest and a time point at which the concentration reaches the lowest by searching the peak time specification (see table 2) of the concentration of the hypertension pill pre-stored in the smart wearable watch; meanwhile, the time point before the user takes the medicine can be taken as the time point when the concentration reaches the lowest; therefore, the user is reminded of carrying out the first blood pressure calibration before taking the medicine, and after the user finishes the first blood pressure calibration, the user is reminded of carrying out the second blood pressure calibration when the medicine concentration reaches the highest time point, and the calibration can be carried out by manually triggering the time reminded by the user.

FIG. 12 illustrates a flow chart for blood pressure calibration of a person taking a medication for hypertension according to an embodiment of the present application; the user is a hypertension medicine taking person, the name of a medicine selected by the user through the prompt message is manidipine, the dose is 20mg, and the medicine taking time is 9:00, the intelligent wearable watch can determine that the time point when the medicine concentration reaches the highest value is 4 hours after the medicine taking, namely 13:00 according to the table 2, the time for the first blood pressure calibration is 13:00, the time point when the medicine concentration reaches the lowest value is about 7.9 hours after the medicine taking, namely about 17:00, and the time for the second blood pressure calibration is 17: 00; meanwhile, if the user-defined scene comprises: a sedentary scene, a recumbent scene, a mental activity scene and an anaerobic exercise scene; the intelligent wearable watch reminds a user to carry out blood pressure calibration at 13:00, and if the user triggers self-defined blood pressure calibration, the intelligent wearable watch can sequentially execute step 1501, blood pressure calibration in a recumbent scene, step 1502, blood pressure calibration in a sitting scene, step 1503, blood pressure calibration in a mental activity scene, and step 1504, blood pressure calibration in an anaerobic exercise scene; thereby completing the first blood pressure calibration. After the first blood pressure calibration is finished, the intelligent wearable watch reminds the user to carry out second blood pressure calibration in 17:00 modes such as voice, vibration and display screen flickering; if the user triggers the user-defined blood pressure calibration, the intelligent wearable watch can sequentially execute step 1501, blood pressure calibration in a lying scene, step 1502, blood pressure calibration in a sitting scene, step 1503, blood pressure calibration in a mental activity scene, and step 1504, blood pressure calibration in an anaerobic exercise scene; thereby completing the second blood pressure calibration.

For example, in the process of performing the first blood pressure calibration or the second blood pressure calibration, the smart wearable watch may sequentially complete the blood pressure calibration in the recumbent scene, the sedentary scene, the mental activity scene and the anaerobic exercise scene by executing the flows shown in fig. 5(a1)/5(a2)/5(a3) -5(e) and the flow shown in fig. 6, so as to complete the first blood pressure calibration or the second blood pressure calibration.

And step 303, the intelligent wearable watch calibrates the blood pressure value according to the calibrated blood pressure value and the acquired physiological signal under different calibration scenes.

Illustratively, when the physiological signals acquired in the calibration scene include PPG signals, based on a pulse wave feature parameter method, a feature value of a preset feature can be calculated through the PPG signals to obtain a feature matrix, and then a blood pressure value corresponding to the feature matrix is marked by using the calibrated blood pressure value acquired in the calibration scene, so as to optimize a corresponding relation between the feature value of the preset feature of the PPG signals and the blood pressure value, thereby completing calibration.

The blood pressure calibration and the further blood pressure measurement process will be described below by taking the pulse wave feature parameter method as an example.

The intelligent wearable watch calculates the feature value of the preset features according to the PPG signal acquired under the above calibration scenario, the number of the preset features may be one or more, and exemplarily, the preset features may include: pulse width, PPG signal period, PPG signal amplitude, peak value, trough value of the PPG signal waveform, and so on.

The intelligent wearable watch generates a feature matrix corresponding to the calibration scene according to the feature value of the preset feature, and the feature matrix can represent the body state of the user in the calibration scene; and marking the blood pressure value corresponding to the characteristic matrix by using the calibration blood pressure value obtained in the calibration scene. Illustratively, the feature matrix may be represented as

Where m represents the number of features, and j represents the number corresponding to this calibration of the calibration scenario, for example, in the recumbent scenario above, calibration performed during 1 minute of recumbency is taken as a primary calibration of the scenario.

Respectively corresponding characteristic values of different preset characteristics. The calibration blood pressure value obtained by the calibration of the calibration scene is X ^j Then use X ^j Marking

So as to obtain the corresponding relation between the calibrated blood pressure value and the characteristic matrix, and recording the corresponding relation as

Therefore, the operation is repeated for each blood pressure calibration under different calibration scenes, a feature matrix corresponding to each blood pressure calibration under each calibration scene and a calibration blood pressure value corresponding to the feature matrix can be obtained, so that the corresponding relation between the calibration blood pressure value and the feature matrix of the PPG signal can be established, and the feature matrix and the corresponding relation are stored in the intelligent wearable watch.

Further, the monitoring method may further include: the watch is worn to intelligence after utilizing above-mentioned blood pressure calibration, measures user's blood pressure. Wherein, the wrist-watch is dressed to the intelligence that the user can be through wearing after the blood pressure calibration, realizes 24 hours continuous blood pressure monitoring. The user can utilize the intelligence after the calibration to dress the wrist-watch under a certain scene, accomplishes the blood pressure and measures. For example, the user may trigger an instruction to enter the measurement mode by clicking the virtual key 401 of the measurement mode on the display screen of the smart wearable watch 101 in fig. 4 while keeping the sitting posture still, and the smart wearable watch 101 enters the measurement mode in response to the instruction, starts blood pressure measurement, acquires a PPG signal, predicts a blood pressure value according to the PPG signal, and displays the predicted blood pressure value.

In one possible implementation, the smart wearable watch acquires a PPG signal in a measurement mode, and predicts a blood pressure value according to the PPG signal, which may include: and calculating a characteristic value of a preset characteristic according to the PPG signal, generating a characteristic matrix corresponding to the current measurement according to the characteristic value of the preset characteristic, and determining one or more pre-stored characteristic matrixes similar to the characteristic matrix corresponding to the current measurement in the pre-stored characteristic matrixes so as to obtain the current measured blood pressure value.

Exemplarily, a range where the feature matrix is located may be represented by using a state space, where the feature matrix obtained in the different calibration scenarios may be used as known points in the state space, and each known point corresponds to one calibration blood pressure value; and the feature matrix corresponding to the current measurement is a point to be determined in the state space, so that the blood pressure value of the point to be determined is obtained according to the distance between the point to be determined and one or more known points in the state space and the calibration blood pressure value corresponding to the known points. Therefore, each time of blood pressure calibration completed under the preset calibration scene can induce the change of factors influencing blood pressure, such as heart rate, stroke volume, cardiac output, peripheral resistance and the like of the user, and obtain characteristic matrixes obtained under different calibration scenes of the user, wherein different characteristic matrixes form a state space.

For example, fig. 13 shows a schematic diagram of a state space according to an embodiment of the present application, as shown in fig. 13, where each point in the state space represents a feature matrix of a PPG signal obtained in each calibration under a different calibration scenario, and different dots in the diagram represent the feature matrix obtained in each calibration under the above-mentioned standard scenario, where dots of the same pattern represent the feature matrices obtained in the same calibration scenario. In the state space, the j point

Corresponding blood pressure value X ^j Can be expressed as

Wherein the content of the first and second substances,

the values of the m features at the j-th point are represented.

Fig. 14 is a schematic diagram illustrating a method for predicting blood pressure using state space according to an embodiment of the present application, and as shown in fig. 14, a feature matrix of a PPG signal obtained in a current blood pressure measurement process is (y) ₁ ,y ₂ ,…,y _m ) I.e. the points represented by the triangles in the figure; the current blood pressure value may be recorded as Y (Y) ₁ ,y ₂ ,…,y _m ) Then, the distance between the point in the state space corresponding to the current blood pressure measurement of the user and each point in the state space can be represented as:

wherein m represents the number of features contained in the feature matrix, i represents the ith feature in the feature matrix, and X ^j To representBlood pressure value, D, corresponding to the jth point in the state space ^j Represents the distance between the point in the state space corresponding to the current measurement and the jth point in the state space,

value, y, of the i-th feature representing the j-th point _i A value representing the ith feature of a feature matrix of the resulting PPG signal; p is an optional parameter, typically 2.

The distances between the midpoint of the state space and the points in the state space (i.e., multiple D) corresponding to the obtained sub-blood pressure measurements ^j (Y,X ^j ) Is subjected to a normalization process so that

Thus, n points in the state space, i.e. points in the circular area in fig. 14, are determined, and the blood pressure values corresponding to these n points are determined by the formula:

the blood pressure value Y of the current blood pressure measurement can be predicted.

Therefore, when the blood pressure is measured, according to the feature matrix obtained under the current measurement scene and the pre-stored feature matrix, the calibration blood pressure values which are most similar to the current measurement scene for one time or several times are selected, the calibration blood pressure values are subjected to weighted summation to obtain the predicted current measured blood pressure value, the weighting coefficient can be in negative correlation with the distance between the feature matrix corresponding to the calibration blood pressure value and the feature matrix obtained under the current measurement scene, namely, the smaller the distance is, the larger the weight occupied by the corresponding calibration blood pressure value is, the blood pressure measurement range is enlarged, and the accuracy of blood pressure measurement is improved.

It can be seen from the calibration and prediction processes that the more the blood pressure calibration times, the richer the calibration scene, the more the points of the state space, the richer the distribution range, and the higher the accuracy of blood pressure prediction; in the embodiment of the application, under different calibration scenes, the blood pressure influence factors of a user such as heart rate, heart beat volume, total peripheral resistance and the like are changed, and calibration is performed under different calibration scenes, so that the number and the distribution range of points in a state space are enriched, and the predicted value of the blood pressure obtained by actual measurement is more accurate.

Further, the body state of the user or the state of the environment where the user is located can be continuously changed, the intelligent wearable watch can be periodically or irregularly calibrated to measure the blood pressure, and therefore accuracy of blood pressure measurement of the calibrated intelligent wearable watch is improved.

For example, the smart wearable watch may remind the user to perform blood pressure calibration when monitoring that the blood pressure value measured by the smart wearable watch is abnormal. For example, when a user configures the intelligent wearable watch to continuously monitor blood pressure, the air bag and the pressure sensor of the intelligent wearable watch can regularly (for example, every 1 day) measure the blood pressure value of the user, and compare the blood pressure value with the blood pressure value measured by the PPG sensor of the intelligent wearable watch at the same time point or an adjacent time point, if the blood pressure value exceeds a preset threshold value, the user is reminded of blood pressure calibration, and therefore self-monitoring of the blood pressure measurement precision of the intelligent wearable watch is achieved.

Illustratively, the smart wearable watch may periodically remind the user to perform blood pressure calibration; wherein, this cycle can be that intelligence is dressed the wrist-watch and is dispatched the preset cycle, also can be that intelligence is dressed the wrist-watch and is responded to user's blood pressure calibration cycle setting operation, the cycle of confirming, for example, when the user used the blood pressure measurement function of intelligence wearing wrist-watch for the first time, intelligence is dressed the wrist-watch and can show blood pressure calibration cycle setting option to the user through the display screen, if: 1 day, 1 week, a month etc. intelligence is dressed the wrist-watch and is operated according to user's cycle selection, confirms the blood pressure calibration cycle, and then when satisfying the blood pressure calibration cycle, reminds the user to carry out the blood pressure calibration.

For example, when the user uses the blood pressure measurement function of the smart wearable watch for the first time or the user does not perform blood pressure calibration for a long time, the smart wearable watch may remind the user to perform blood pressure calibration, and the user may autonomously select whether to perform blood pressure calibration; for another example, the user may perform a blood pressure calibration when feeling a change in the physical state of the user or the state of the environment in which the user is located.

In the embodiment of the application, the user is prompted to complete physical activities according with a plurality of calibration scenes through prompt information; after the user has completed physical activity that conforms to 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 calibration blood pressure value of the user under each calibration scene is measured, corresponding physiological signals are collected, the change of blood pressure influence factors of the user is fully captured, and the blood pressure calibration under a plurality of calibration scenes is realized; in the blood pressure measuring stage, the blood pressure value of the user to be measured is determined according to the collected physiological signals, the blood pressure value calibrated under each calibration scene and the corresponding physiological signals, the blood pressure value has higher precision, and the accurate measurement of the blood pressure of the user is realized; meanwhile, the blood pressure calibration process does not need to use other equipment, the operation is convenient, and the user experience is improved.

The blood pressure monitoring method provided by the present application is described below with reference to the application scenario shown in fig. 2.

Fig. 15 shows a flow chart of a blood pressure monitoring method according to an embodiment of the present application, which may include the following steps, as shown in fig. 15:

step 1801, the smart wearable watch responds to the instruction of the user and enters a calibration mode.

The manner of entering the calibration mode in this step can refer to the related description in step 301 of fig. 3, and is not described herein again.

For example, as shown in fig. 2, if the smart wearable watch 101 can be connected to the blood pressure monitor 102 in a bluetooth or WIFI equidistant communication manner, after entering the calibration mode, the smart wearable watch can send an instruction for preparing blood pressure measurement to the blood pressure monitor, so that the blood pressure monitor performs a preparation state for measuring blood pressure.

For example, in fig. 2, when smart wearable watch 101 enters a calibration mode, the user may manually operate the mode so that blood pressure monitor 102 performs a ready state for measuring blood pressure.

Step 1802, the intelligent wearable watch collects physiological signals of a user under different calibration scenes and acquires a calibration blood pressure value measured by the blood pressure monitor.

In the step, according to different preset calibration scenes, the intelligent wearable watch collects physiological signals of the user in different calibration scenes. Meanwhile, the blood pressure monitor measures the blood pressure value of the user as a calibration blood pressure value by an oscillometric method.

In a possible implementation, the wrist-watch is dressed to intelligence under different calibration scenes, gathers user's physiological signal to obtain the calibration blood pressure value that blood pressure monitor surveyed, can include: the blood pressure monitor can measure a calibration blood pressure value under the calibration scene through an oscillography, and meanwhile, the intelligent wearable watch collects physiological signals of a user; the time for measuring the calibration blood pressure value under the calibration scene by the blood pressure monitor can be before the time for acquiring the physiological signal under the scene of the user or after the time for acquiring the physiological signal under the scene of the user; the time for measuring the calibration blood pressure value under the calibration scene by the blood pressure monitor can be the same as the time for acquiring the physiological signal of the user under the scene, namely, the physiological signal of the user is acquired while the calibration blood pressure value is measured.

For example, the smart wearable watch may send an instruction to the blood pressure monitor to begin measuring blood pressure; meanwhile, the PPG sensor of the watch is worn to intelligence begins to work, acquires the PPG signal of the user, or the PPG sensor and the ECG sensor of the watch are worn to intelligence begins to work, acquires the PPG signal and the ECG signal of the user. After the blood pressure monitor receives the instruction, a calibrated blood pressure value under the scene is obtained through an oscillography, and the calibrated blood pressure value is sent to the intelligent wearable device. For example, when the smart wearable watch and the blood pressure monitor are respectively worn on different side arms of a user, the smart wearable watch sends an instruction for starting to measure the blood pressure to the blood pressure monitor while starting to collect physiological signals of the user. In this way, the calibrated blood pressure and physiological signals of the user can be measured simultaneously.

For example, the intelligent wearable watch may send an instruction to start measuring blood pressure to the blood pressure monitor, and after receiving the instruction, the blood pressure monitor obtains a calibrated blood pressure value in the scene through an oscillography, and sends the calibrated blood pressure value to the intelligent wearable device; after receiving the calibrated blood pressure value or after a certain time interval, the intelligent wearable device starts to acquire the physiological signal of the user in the calibration scene. For example, when wrist-watch and blood pressure monitor are dressed to intelligence and are worn respectively on user ' S different side arms, wrist-watch can be dressed to intelligence after receiving this calibration blood pressure value, or after interval 30S, the work is started to the PPG sensor of wrist-watch is dressed to intelligence, gathers user ' S PPG signal, or the work is started to PPG sensor and the ECG sensor of wrist-watch is dressed to intelligence, gathers user ' S PPG signal and ECG signal. Therefore, the influence of the air pressure change on the acquisition of physiological signals when the blood pressure monitor measures the blood pressure can be avoided, and the measurement accuracy is improved.

Illustratively, a user can trigger a blood pressure monitor to start working during measurement through manual operation, and at the same time, a PPG sensor of the smart wearable watch starts working to acquire a PPG signal of the user, or the PPG sensor and an ECG sensor of the smart wearable watch start working to acquire the PPG signal and the ECG signal of the user. After the blood pressure monitor and the intelligent wearable watch finish measurement, the user can input the calibrated blood pressure value obtained by the blood pressure monitor into the intelligent wearable watch. For example, when wrist-watch and blood pressure monitor are dressed to intelligence and are worn respectively on user's different side arms, the user can trigger the blood pressure monitor through manual operation and measure the work of beginning, and simultaneously, the wrist-watch is dressed to intelligence begins to gather user's physiological signal. In this way, the calibrated blood pressure and physiological signals of the user can be measured simultaneously. Illustratively, a user can trigger the blood pressure monitor to measure through manual operation, so as to obtain a calibrated blood pressure value under the scene; then, the user can input this calibration blood pressure value to intelligence wearing wrist-watch, after intelligence wearing wrist-watch received this calibration blood pressure value of user' S input, or after the interval certain time (like 30S), begin to gather the physiological signal of user under this calibration scene, perhaps, the user can trigger the blood pressure measurement function of intelligence wearing wrist-watch through operations such as clicking the start button for intelligence is worn the wrist-watch and is begun to gather the physiological signal of user under this calibration scene, after the collection finishes, the user is at the input calibration blood pressure value of intelligence wearing wrist-watch.

In this step, the contents of the calibration scenario, the physiological signal, and the like can refer to the related description in step 301 in fig. 3, and are not described herein again.

The following describes the process of completing blood pressure calibration by a user through an intelligent wearable watch and a blood pressure monitor in different calibration scenes by taking a sitting scene, a lying scene, a mental activity scene, a relaxation/rest scene and an anaerobic exercise scene as examples.

Or, the intelligence is dressed the wrist-watch and can also be sent the instruction to blood pressure monitor, and blood pressure monitor response measures user's calibration blood pressure value with this instruction to send this calibration blood pressure value to intelligence and dress the wrist-watch, intelligence is dressed the wrist-watch and is receiving this calibration blood pressure value after, begins to gather user's physiological signal, perhaps interval certain time, begins to gather user's physiological signal. Therefore, in the calibration process, the user can finish the calibration through simple operation, and the user experience is improved.

Exemplarily, when the smart wearable watch and the blood pressure monitor are respectively worn on different arms of the user and the user triggers the blood pressure monitor to measure through manual operation, the blood pressure calibration process in the sitting scene, the lying scene, the mental activity scene, the relaxation/rest scene and the anaerobic exercise scene is as shown in fig. 16 to 17.

The wearable device displays a third graphical user interface in response to the first operation, e.g., the third graphical user interface may be as shown in fig. 9 (b). Responding to the selection operation of a user on the calibration scenes, and sequentially displaying a graphical user interface corresponding to the calibration scene selected by the user according to the preset sequence of each calibration scene in the calibration scenes, so as to prompt the user to perform actions under each calibration scene; the calibration scenario selected by the user may include any number of calibration scenarios in the plurality of calibration scenarios displayed by the third graphical user interface, for example, the plurality of calibration scenarios may refer to the related examples or expressions about the custom scenario in fig. 9 and 10 above; therefore, the user can select the most suitable and matched calibration scene to finish calibration according to daily activities of the user, so that the calibration is more personalized and more specific, the calibration time is effectively reduced, and the user experience is improved.

Illustratively, the calibration scenario corresponds to one or more of a calibration scenario of a physical state of the user, a calibration scenario of a state of an environment in which the user is located. Therefore, under different calibration scenes, the body state of the user, the state of the environment where the user is located and the like are different, correspondingly, the blood pressure influence factors of the user, such as heart rate, heart stroke volume, total peripheral resistance and the like, change, and the blood pressure influence factors of the user are induced to change through the body states of the user or the states of the environment where the user is located, so that the change of the blood pressure influence factors of the user is fully captured, and the blood pressure calibration of the user under different states of the body or different states of the environment where the user is located is realized.

For example, the calibration scenario corresponding to the state of the environment in which the user is located may include one or more of a cold scenario, a hot scenario; wherein, when the user is in the environment of the cold scene, the peripheral blood vessel contracts, the peripheral resistance is increased, and the blood pressure is raised; the user is in the environment of a sultry scene, peripheral blood vessels relax, peripheral resistance is reduced, and blood pressure is lowered. Therefore, under different scenes, blood pressure influence factors of the user such as heart rate, heart stroke, total peripheral resistance and the like change, and the provided multiple calibration scenes can comprehensively cover the change situation of the blood pressure influence factors of the user, so that blood pressure calibration under different scenes is realized, and the blood pressure measurement precision of the calibrated wearable device is improved.

In a possible implementation manner, after the displaying the first graphical user interface, the method further includes: displaying a fourth graphical user interface, the fourth graphical user interface displaying timing information.

In the embodiment of the application, when the calibrated wearable device is used for measuring the blood pressure of a user, the target blood pressure value corresponding to the target physiological index information with the similarity greater than the second threshold value is subjected to weighted summation by determining the target physiological index information with the similarity greater than the second threshold value in the plurality of physiological index information obtained in the calibration stage, so as to obtain a third blood pressure value of the user; in this way, the target blood pressure values which are obtained in the calibration stage and are most similar to the current measurement scene once or several times are selected, the target blood pressure values are subjected to weighted summation, a third blood pressure value which is measured currently is obtained through prediction, and the weight of each target blood pressure value is positively correlated with the similarity of the corresponding target physiological index information and the third physiological index information; that is, the higher the similarity is, the more the corresponding target blood pressure value occupies the weight, thereby increasing the blood pressure measurement range and improving the accuracy of blood pressure measurement.

For example, the similarity may be represented by a distance between a feature matrix corresponding to the first physiological index information and a feature matrix corresponding to the third physiological index information obtained in the current measurement scenario, e.g., a distance between a point representing the feature matrix corresponding to the first physiological index information and a point representing the feature matrix corresponding to the third physiological index information obtained in the current measurement scenario in the state space shown in fig. 13. The second threshold may be preset, which is not limited in the embodiment of the present application; determining target physiological index information corresponding to each point of the feature matrix corresponding to the third physiological index information, wherein the distance between the points of the feature matrix is greater than a second threshold value, and selecting one or more target blood pressure values most similar to the current measurement scene; the smaller the distance is, the larger the weight occupied by the corresponding target blood pressure value is; obtaining a third blood pressure value of the user by weighting and summing the target blood pressure values; the specific implementation process can be referred to the related expressions in fig. 13-14.

In this embodiment of the application, the first time may represent a time point at which the concentration of the drug in the body of the user is highest, the second time may represent a time point at which the concentration of the drug in the body of the user is lowest, and the fifth graphical user interface may display a pattern for performing blood pressure calibration, for example, a "blood pressure" icon as shown in fig. 4(a) above, and may also display text for performing blood pressure calibration. The medicine taken by the user can be hypotensor, and the time point of the highest medicine concentration in the body of the user and the time point of the lowest medicine concentration in the body of the user can be determined according to the type, the dosage and the medicine taking time of the hypotensor taken by the user and shown in the table 2, and the user is reminded of carrying out blood pressure calibration at the two time points; the specific implementation can be referred to in fig. 11A, fig. 11B and fig. 12.
