[0001] This application claims priority to the Chinese patent application with application number 202311442868.2 filed with the State Intellectual Property Office of China on October 31, 2023, and priority to the Chinese patent application entitled “A blood pressure measurement scheme generating method, electronic device and storage medium”, all contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of wearable technology, and in particular to a method for generating a blood pressure measurement solution, an electronic device, and a storage medium. Background Art

[0003] With the improvement of living standards, people's physical health has received more and more attention. As a common cardiovascular disease, hypertension, regular blood pressure measurement is one of the important means to ensure the health of hypertensive patients. Dynamic blood pressure measurement is a technology that measures the user's blood pressure continuously for 24 hours without affecting the user's daily activities, and can obtain multiple blood pressure measurement values ​​within 24 hours. Generally, the measurement is taken every 10-15 minutes, and the average of multiple blood pressure measurements within 24 hours is taken as the blood pressure value. Currently, there are cuff-type blood pressure monitors to measure the user's dynamic blood pressure, but the cuff-type blood pressure monitor requires the user to carry the cuff-type blood pressure monitor 24 hours a day, which is inconvenient for the user to use.

[0004] To facilitate blood pressure measurement, wearable devices (such as watches) are equipped with blood pressure detection devices. Users can perform dynamic blood pressure measurement on the wearable device, saving time and effort. Users can set a blood pressure measurement plan on the wearable device, such as setting the measurement time and the interval between two consecutive blood pressure measurements. However, manually setting a blood pressure measurement plan is cumbersome, and further research is needed to reduce user effort.

[0005] Summary of the Invention

[0006] The present application provides a blood pressure measurement plan generation method, an electronic device, and a storage medium, which enable a wearable device to automatically generate a blood pressure measurement plan for a user, so that the blood pressure measurement plan generated by the wearable device is more in line with the user's characteristics and living habits, thereby improving the rationality of blood pressure measurement.

[0007] In a first aspect, the present application provides a method for generating a blood pressure measurement scheme, the method comprising: a wearable device obtains one or more of user information, physiological data, and device status; the wearable device generates a blood pressure measurement scheme based on one or more of the user information, physiological data, and device status, the blood pressure measurement scheme including one or more of the following: the start time of the blood pressure measurement, the end time of the blood pressure measurement, the duration of the blood pressure measurement, the number of blood pressure measurements within the duration of the blood pressure measurement, the time interval between two adjacent blood pressure measurements within the duration of the blood pressure measurement, and the total number of blood pressure measurements; the wearable device obtains the blood pressure measurement value of the user within a blood pressure measurement cycle based on the blood pressure measurement scheme.

[0008] For example, a blood pressure measurement cycle may be a 24-hour cycle.

[0009] Through this method, wearable devices can automatically generate blood pressure measurement plans based on the fusion of multiple information, so that the blood pressure measurement plans generated by wearable devices are more in line with user characteristics, which not only saves user operations but also improves the rationality of blood pressure measurement.

[0010] In combination with the first aspect, in one possible implementation, user information includes one or more of the following: gender, age, height, weight, smoking history, drinking history, medical history, medication history, and living habits; physiological data includes one or more of the following: heart rate, blood pressure, arteriosclerosis, and blood sugar; device status includes one or more of the following: remaining power and device temperature.

[0011] In combination with the first aspect, in one possible implementation method, the wearable device generates a blood pressure measurement plan based on one or more of user information, physiological data and device status, specifically including: the wearable device determines the risk level of the user's hypertension risk based on one or more of user information, physiological data and device status; the wearable device generates a blood pressure measurement plan based on the user's hypertension risk level.

[0012] Different blood pressure measurement plans are generated for different risk levels of hypertension. For example, the total number of blood pressure measurements determined by a wearable device based on a high risk is greater than the total number of blood pressure measurements determined by a wearable device based on a low risk.

[0013] In some embodiments, the risk level of hypertension risk may refer to the risk level within a certain time period within a blood pressure measurement cycle. For example, if a user's risk level of hypertension risk during the nighttime period is greater than the user's risk level of hypertension risk during the daytime period, then the total number of blood pressure measurements during the nighttime period is greater than the total number of blood pressure measurements during the daytime period.

[0014] In this way, the wearable device can determine the user's risk level of hypertension based on various information, and then generate a blood pressure measurement plan based on the risk level of hypertension.

[0015] In combination with the first aspect, in a possible implementation, after the wearable device generates a blood pressure measurement plan, the method also includes: the wearable device displays a first prompt message, and the first prompt message is used to prompt the user to view the details of the blood pressure measurement plan; the wearable device receives and responds to the user's first operation on the first option in the first prompt message, and displays a first user interface, in which the details of the blood pressure measurement plan are displayed.

[0016] In this way, after the wearable device automatically generates a blood pressure measurement plan, the wearable device can prompt the user to view the details of the blood pressure measurement plan. In some embodiments, the wearable device can also receive user operations to modify the blood pressure measurement plan.

[0017] In combination with the first aspect, in a possible implementation, before the wearable device obtains the blood pressure measurement value of the user within a blood pressure measurement cycle based on the blood pressure measurement scheme, the method also includes: the wearable device obtains the remaining power of the wearable device; when the remaining power of the wearable device is less than a preset power, the wearable device displays a second prompt message, and the second prompt message is used to prompt the user to charge the wearable device, wherein the preset power is the minimum power required for the wearable device to complete the blood pressure measurement within a blood pressure measurement cycle based on the blood pressure measurement scheme; when the wearable device is in a charging state within a first period of time after the second prompt message is displayed, the blood pressure measurement scheme is saved.

[0018] Before the wearable device measures blood pressure based on the automatically generated blood pressure measurement plan, it must determine whether the remaining battery power is sufficient. This prevents the wearable device from shutting down before completing a blood pressure measurement cycle. After the wearable device displays a prompt message and is charging, it can save the blood pressure measurement plan and complete blood pressure measurements within a blood pressure measurement cycle based on the blood pressure measurement plan.

[0019] In combination with the first aspect, in a possible implementation, the method also includes: when the wearable device is not in a charging state within a first period of time after displaying the second prompt information, the wearable device displays a third prompt information, and the third prompt information is used to prompt the user to change the blood pressure measurement plan; the wearable device receives and responds to the user's second operation for the second option in the third prompt information, obtains and saves a first updated blood pressure measurement plan, and the total number of blood pressure measurements in the first updated blood pressure measurement plan is less than the total number of blood pressure measurements in the blood pressure measurement plan; the wearable device obtains the user's blood pressure measurement value in a blood pressure measurement cycle based on the first updated blood pressure measurement plan.

[0020] Optionally, the power required by the first updated blood pressure measurement scheme to complete blood pressure measurement within a blood pressure measurement cycle is less than or equal to the remaining power of the wearable device.

[0021] In this way, when the wearable device is still not in the charging state after the wearable device displays the prompt information, the wearable device can prompt the user again to modify the blood pressure measurement plan and obtain a first updated blood pressure measurement plan.

[0022] In combination with the first aspect, in a possible implementation, the method also includes: the wearable device receives and responds to the user's third operation for the third option in the third prompt information, displays a fourth prompt information, and the fourth prompt information is used to prompt the user to set the wearable device to low power mode; the wearable device receives and responds to the user's fourth operation for the fourth option in the fourth prompt information, and enters the low power mode.

[0023] Optionally, the low power consumption mode may refer to shutting down some or all energy-consuming operations on the wearable device 100 that are not related to blood pressure monitoring. For example, energy-consuming operations may include but are not limited to heart rate monitoring functions, motion data recording functions, etc.

[0024] In this way, if the user has not modified the blood pressure measurement plan after the wearable device displays the prompt information, the wearable device can prompt the user again to control the wearable device to enter the low power mode to save the power of the device.

[0025] In combination with the first aspect, in a possible implementation, the method also includes: the wearable device receives and responds to the user's fifth operation on the fifth option in the fourth prompt information, and displays a fifth prompt information, where the fifth prompt information is used to prompt the user that the battery of the wearable device is too low.

[0026] In this way, if the wearable device has not entered the low power mode after displaying the prompt message, the wearable device can remind the user that the device battery is too low and may shut down at any time.

[0027] In conjunction with the first aspect, in one possible implementation, the blood pressure measurement value includes a first blood pressure measurement value obtained by the wearable device at a first moment; after the wearable device obtains the first blood pressure measurement value, the method further includes: the wearable device obtaining a current user state; if the current user state meets the blood pressure measurement condition, the wearable device saves the first blood pressure measurement value

[0028] In one possible implementation, the method further includes: when the current user status does not meet the blood pressure measurement conditions, the wearable device obtains a blood pressure compensation value based on the current user status; the wearable device obtains a first blood pressure monitoring value based on the blood pressure compensation value and the first blood pressure measurement value; and the wearable device saves the first blood pressure monitoring value.

[0029] The blood pressure measurement conditions may include but are not limited to one or more of the following: the user is in a stationary state, and the difference between the real-time heart rate and the nighttime resting heart rate is within a preset range.

[0030] Wearable devices can collect motion data based on motion sensors. Motion sensors may include, but are not limited to, accelerometers, gyroscopes, etc. Motion sensors can collect motion data or motion trajectories. Wearable devices can determine whether the user is stationary based on the motion data or motion trajectories.

[0031] This allows the wearable device to determine whether the user's condition meets the blood pressure measurement requirements when measuring blood pressure. If so, the blood pressure measurement result can be directly saved. If not, the wearable device needs to correct the blood pressure measurement result and then save the corrected result, which can improve the accuracy of blood pressure measurement.

[0032] In combination with the first aspect, in a possible implementation, the method also includes: the wearable device obtains historical blood pressure measurement data, wherein the historical blood pressure measurement data includes historical blood pressure measurement records and historical blood pressure measurement results; the wearable device updates the blood pressure measurement scheme based on the historical blood pressure measurement data, generates and saves a second updated blood pressure measurement scheme; the wearable device obtains the blood pressure measurement value of the user within a blood pressure measurement cycle based on the second updated blood pressure measurement scheme.

[0033] Historical blood pressure measurement records include, but are not limited to, historical blood pressure measurement records and historical blood pressure measurement results. Historical blood pressure measurement records may include, but are not limited to, the start time of the historical blood pressure measurement, the end time of the historical blood pressure measurement, the duration of the historical blood pressure measurement, the number of blood pressure measurements within the duration of the historical blood pressure measurement, the time interval between two adjacent blood pressure measurements within the duration of the historical blood pressure measurement, and the total number of historical blood pressure measurements.

[0034] In this way, the wearable device can periodically / irregularly update the blood pressure measurement solution based on the user's historical data to improve the accuracy of the blood pressure measurement solution generated by the wearable device.

[0035] In a second aspect, the present application provides a wearable device, which includes a memory and a processor; wherein the memory and the processor are coupled, and the memory is used to store a computer program. When the processor executes and calls the computer program, the wearable device executes a blood pressure measurement scheme generation method provided in any possible implementation of any of the above aspects.

[0058] The following is a clear and detailed description of the technical solutions in the embodiments of the present application in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in the text is only a description of the association relationship between related objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0059] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to imply or suggest relative importance or implicitly indicate the number of the technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of this application, unless otherwise specified, "plurality" means two or more.

[0060] The term "user interface (UI)" in the following embodiments of this application refers to the media interface for interaction and information exchange between an application or operating system and a user, which realizes the conversion between the internal form of information and the form acceptable to the user. A common form of user interface is a graphical user interface (GUI), which refers to a user interface related to computer operations that is displayed in a graphical manner. It can be a visual interface element such as text, icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, widgets, etc. displayed on the display screen of an electronic device.

[0061] With the advancement of electronic technology, the functionality of wearable devices continues to increase. For example, wearable devices such as wristbands and watches can provide blood pressure measurement functions, allowing users to measure their blood pressure anytime, anywhere and understand their physical condition. Users can wear wearable devices on their wrists to conveniently monitor their blood pressure in real time.

[0062] Next, a wearable device 100 provided in this application for measuring blood pressure is introduced.

[0063] FIG1 shows a schematic diagram of a user wearing a wearable device 100 .

[0064] As shown in FIG1 , a user may wear the wearable device 100 on the user's wrist.

[0065] FIG2 shows a schematic diagram of the structure of the wearable device 100 .

[0066] As shown in FIG. 2 , the wearable device 100 may include a watch body 201 and a wearable component 202 .

[0067] The watch body 201 is equipped with a motion sensor, such as a gyroscope sensor and an acceleration sensor. The motion sensor is used to collect motion data and determine whether the user is in a sleeping state based on the motion state obtained by analyzing the motion data.

[0068] The watch body 201 may include a display screen 203. The display screen 203 may be used to display content such as the time, the battery level of the watch body 201, a Bluetooth identifier, received messages, and user motion data. The display screen 203 may be used to receive user click operations to illuminate the display screen, start and end motion modes, and the like. The display screen 203 may also record the user's steps and calories burned, and provide basic functions such as incoming call reminders and message notifications. In one possible implementation, the watch body 201 may establish a wireless communication connection with the wearable device 100 via Bluetooth. The watch body 201 may send the user's motion data to the connected wearable device 100. Furthermore, when the wearable device 100 receives an incoming call or message notification, the watch body 201 may receive instructions from the mobile phone to remind the user of the incoming call or message notification.

[0069] Wearable component 202 is used to mount watch body 201. For example, wearable component 202 can be a wristband or watch strap. Wearable component 202 is a device that allows watch body 201 to be attached to the user's wrist. When wearable device 100 is attached to the user's wrist, the inertial sensor can collect wrist motion data to monitor wrist movement and determine the user's posture.

[0070] When the wearable device 100 starts to measure blood pressure, the wearable device 100 can control the wearable component 202 to contract and then relax to measure the user's blood pressure.

[0071] In some embodiments, the process of measuring blood pressure by the wearable device 100 may include: first, the wearable device 100 inflates the wearable component 202 to temporarily occlude the arm artery; then, while slowly deflating the air, the wearable device 100 records the air pressure value of the wearable component 202 and the pulse signal generated by the pulse; finally, the user's blood pressure is determined based on the air pressure value of the wearable component 202 and the amplitude or envelope of the pulse signal. Blood flow exerts lateral pressure on the blood vessel wall, and changes in the magnitude of the lateral pressure cause the blood vessel wall to vibrate slightly. The pulse signal is a signal generated by this slight vibration of the blood vessel wall. Determining the user's blood pressure based on the air pressure value of the wearable component 202 and the amplitude or envelope of the pulse signal is also known as the oscillometric method.

[0072] In other embodiments, the process of measuring blood pressure by the wearable device 100 may include: the wearable device 100 may gradually inflate the wearable component 202 so that the arm artery is completely blocked by the component, record the air pressure value of the wearable component 202 and the pulse signal generated by the pulse, then determine the user's blood pressure based on the air pressure value of the wearable component 202 and the amplitude or envelope of the pulse signal, and finally deflate. Among them, blood flow will generate lateral pressure on the blood vessel wall, and the change in the magnitude of the lateral pressure will cause the blood vessel wall to vibrate slightly. The pulse signal is a signal generated by the slight vibration of the blood vessel wall. Among them, determining the user's blood pressure based on the air pressure value of the wearable component 202 and the amplitude or envelope of the pulse signal is also called the oscillometric method.

[0073] FIG3A is an exemplary schematic diagram of the principle of the oscillometric method provided in an embodiment of the present application.

[0074] As shown in Figure 3A, as wearable device 100 inflates wearable component 202 to temporarily occlude an arm artery, the pressure in wearable component 202 gradually increases to a stable state, and the artery gradually becomes completely blocked. Then, as the pressure slowly decreases, the pressure in wearable component 202 gradually decreases to zero, and the artery transitions from completely blocked to unblocked. During this gradual decrease in pressure, the pressure and pulse signal are recorded. When the air pressure value of wearable component 202 is greater than or equal to the systolic pressure, the artery is blocked and the pulse signal is a small oscillatory wave. When the air pressure value of wearable component 202 gradually decreases and becomes less than the systolic pressure and greater than the mean pressure, the artery gradually becomes unblocked and the amplitude of the pulse signal increases continuously. When the air pressure value of wearable component 202 equals the mean pressure, the amplitude of the pulse signal reaches its maximum value. When the air pressure value of wearable component 202 continues to gradually decrease and becomes greater than the diastolic pressure and less than the mean pressure, the amplitude of the pulse signal gradually decreases. When the air pressure value of wearable component 202 is less than the diastolic pressure, the pulse signal is a small oscillatory wave. Therefore, wearable device 100 can determine the user's systolic and diastolic blood pressure by the amplitude changes of the pulse signal and the air pressure value of wearable component 202. In one possible implementation, the air pressure value of wearable component 202 and the pulse signal can be determined by a built-in air pressure sensor in wearable device 100.

[0075] FIG3B is another exemplary schematic diagram of the principle of the oscillometric method provided in an embodiment of the present application.

[0076] As shown in Figure 3B, while the wearable device 100 inflates the wearable component 202 to temporarily occlude the arm artery, the pressure in the wearable component 202 gradually increases to a stable state, and the artery gradually becomes completely blocked. During this period of gradual pressure increase, the air pressure and pulse signal of the wearable component 202 are recorded. When the air pressure in the wearable component 202 gradually increases and the diastolic pressure is less than the mean pressure, the pulse signal is a fine oscillatory wave. As the air pressure in the wearable component 202 continues to increase and becomes greater than the diastolic pressure but less than the mean pressure, the pulse signal amplitude gradually increases. When the air pressure in the wearable component 202 equals the mean pressure, the pulse signal amplitude reaches its maximum value. When the air pressure in the wearable component 202 gradually increases and becomes greater than the mean pressure but less than the systolic pressure, the artery gradually becomes blocked, and the pulse signal amplitude continuously decreases. When the air pressure in the wearable component 202 becomes greater than or equal to the systolic pressure, the artery is blocked, and the pulse signal is a fine oscillatory wave. Therefore, the wearable device 100 can determine the user's systolic and diastolic blood pressures by the amplitude change of the pulse signal and the air pressure value of the wearable component 202. In one possible implementation, the air pressure value of the wearable component 202 and the pulse signal can be determined by a built-in air pressure sensor in the wearable device 100.

[0077] FIG4A shows a schematic diagram of the hardware structure of the wearable device 100 .

[0078] As shown in FIG4A , the wearable device can be a wearable device such as a bracelet, a watch, etc., and the wearable device 100 can also be a non-wearable device such as a wall-mounted blood pressure monitor. The embodiment of the present application does not impose any particular restrictions on the specific type of the wearable device. The embodiment of the present application is only described by taking the wearable device 100 as a watch as an example.

[0079] Wearable device 100 may include: a processor 200A, a wireless communication module 201, a mobile communication module 202, a sensor module 203, a button 204, a display 205, a motor 206, an internal memory 207, a SIM card interface 208, a USB interface 209, a power management module 210, a battery 211, and a charging management module 212. Sensor module 203 may include a touch sensor 203A, an air pressure sensor 203B, an air pump 203C, an airbag 203D, a magnetic sensor 203E, a photoplethysmography (PPG) sensor 203F, a motion sensor 203G, and an air path conducting component 203H. The airbag 203D has similar functions to the wearable component 202.

[0080] It is understood that the structures illustrated in the embodiments of the present invention do not constitute specific limitations on wearable devices. In other embodiments of the present application, the wearable device may include more or fewer components than shown, or combine or separate certain components, or arrange the components differently.

In some embodiments, the processor 200A may include multiple I2C bus lines. The processor 200A may be coupled to the touch sensor 203A, the power management module 210, and the like via different I2C bus interfaces. For example, the processor 200A may be coupled to the touch sensor 203A via the I2C interface, enabling communication between the processor 200A and the touch sensor 203A via the I2C bus interface, thereby enabling touch functionality for the wearable device.

[0085] The I2S interface can be used for audio communication. The PCM interface can also be used for audio communication to sample, quantize, and encode analog signals. The UART interface is a universal serial data bus used for asynchronous communication. This bus can be a bidirectional communication bus. It converts the data to be transmitted between serial communication and parallel communication. In some embodiments, the UART interface is typically used to connect the processor 200A and the wireless communication module 201.

The USB interface 209 can be used to connect a charger to charge the wearable device and can also be used to transfer data between the wearable device and peripheral devices.

[0088] It is understood that the interface connection relationship between the modules illustrated in the embodiments of the present invention is only a schematic illustration and does not constitute a structural limitation on the wearable device. In other embodiments of the present application, the wearable device may also adopt a different interface connection method from the above embodiments, or a combination of multiple interface connection methods.

[0089] The charging management module 212 is configured to receive charging input from a charger. The charger can be either a wireless charger or a wired charger.

[0103] Air pressure sensor 203B is used to measure air pressure. In some embodiments of the present application, the wearable device uses air pressure sensor 203B to measure the air pressure in airbag 203D. In some embodiments of the present application, a portion of air pressure sensor 203B is located inside airbag 203D to sense the air pressure in airbag 203D.

[0104] Air pump 203C is used for inflation and deflation. In some embodiments of the present application, the wearable device inflates airbag 203D via air pump 203C, wherein air pump 203C and airbag 203D are connected via air path conducting component 203H. Airbag 203D is used to squeeze the user's blood vessels.

[0105] Magnetic sensor 203E includes a Hall sensor. In some embodiments of the present application, the wearable device can use magnetic sensor 203F to determine whether the airbag 203D on the wearable device has been removed. For example, a magnet can be configured on the airbag 203D or on a watch strap connected to the airbag 203D. The wearable device can use the magnetic sensor to determine the magnetic flux generated by the magnet on the airbag 203D or on the airbag 203D, thereby determining whether the airbag 203D on the wearable device has been removed.

[0106] The PPG sensor 203F user obtains the user's health data based on the PPG signal collected by the PPG sensor 203F. The user's health data includes but is not limited to: heart rate, blood oxygen, respiratory rate, blood oxygen saturation (SaO2), etc.

[0107] The motion sensor 203G includes but is not limited to an acceleration sensor and an angular velocity sensor. The motion sensor 203G can be used to collect motion data and determine the user's motion state based on the motion data, and then determine whether the user is in a sleeping state based on the user's motion state.

[0108] It is worth noting that the air path conducting component 203H can be a separate component, or the air path conducting component 203H can also be an air path formed by the combination of other hardware modules, or the air path conducting component 203H can also be a part of other components, for example, it can be a part of the air pump 203C, or it can be a part of the airbag 203D.

[0109] It is worth noting that the sensor module 203 may also include an acceleration sensor, an infrared sensor, etc.

[0110] As shown in Figure 4B, when the wearable device 100 is a watch, the airbag 203D is attached to the body-facing side of the wearable component 202.

[0111] The air pump 203C can be located inside the body of the smartwatch, and the airbag 203D can be connected to the watchband buckle, and the airbag 203D is connected to the dial through the air hole cover. Correspondingly, the airbag 203D can be separated from the watchband or the dial.

[0112] Currently, the user can set a blood pressure measurement plan on the wearable device 100 .

[0113] A blood pressure measurement plan may include one or more blood pressure measurement strategies, which may include but are not limited to: the start time of the blood pressure measurement, the end time of the blood pressure measurement, the duration of the blood pressure measurement, the number of blood pressure measurements within the duration of the blood pressure measurement, the time interval between two adjacent blood pressure measurements within the duration of the blood pressure measurement, the total number of blood pressure measurements, etc.

[0114] The start time of blood pressure measurement may refer to the time of day at which the user's blood pressure is measured. For example, the start time of blood pressure measurement may be 9 o'clock in the morning or 10 o'clock in the evening.

[0115] The end time of blood pressure measurement may refer to the time during the day at which the user's blood pressure measurement stops. For example, the end time of blood pressure measurement may be 12 noon or 6 am.

[0116] The duration of a blood pressure measurement may refer to the time between which the user's blood pressure is measured during a day. A blood pressure measurement duration within a day may include one or more time periods. For example, a blood pressure measurement duration may be from 9:00 AM to 12:00 PM, and / or from 10:00 PM to 6:00 AM the following day.

[0117] The blood pressure measurement frequency within a blood pressure measurement duration may refer to the total number of blood pressure measurements within a blood pressure measurement duration. For example, if the blood pressure measurement duration is from 9:00 AM to 12:00 PM, the blood pressure measurement frequency is 6 times. If the blood pressure measurement duration is from 10:00 PM to 6:00 AM the next day, the blood pressure measurement frequency is 30 times.

[0118] The time interval between two adjacent blood pressure measurements within a blood pressure measurement period may refer to the time difference between the two adjacent blood pressure measurements within a blood pressure measurement period. The time difference between two adjacent blood pressure measurements within a blood pressure measurement period may be the same or different. For example, if the blood pressure measurement period is from 9:00 a.m. to 12:00 p.m., the time difference between two adjacent blood pressure measurements may be 30 minutes.

[0119] The total number of blood pressure measurements may refer to the total number of blood pressure measurements taken within 24 hours between midnight and midnight. For example, the total number of blood pressure measurements taken within one day may be 36.

[0120] The blood pressure measurement scheme is not limited to the above blood pressure measurement strategies, and the blood pressure measurement scheme may also include other blood pressure measurement strategies, which are not limited in this application.

[0121] 5A-5D are schematic diagrams showing a user manually setting a blood pressure measurement plan.

[0122] For example, the wearable device 100 may display the user interface 510 shown in Figure 5A. The user interface 510 shows options 501 and 502. The user may manually set a blood pressure measurement plan through options 501 and 502.

[0123] For example, as shown in FIG5A , the wearable device 100 may receive a user input operation (e.g., a click) for option 501 in the user interface 510. In response to the user input operation, the wearable device 100 may display the user interface 520 shown in FIG5B . The user interface 520 shows a portion of the blood pressure measurement strategy of the blood pressure measurement scheme, such as the user can manually set the time interval between two adjacent blood pressure measurements during the day and the time interval between two adjacent blood pressure measurements at night. For example, the time interval between two adjacent blood pressure measurements during the day set by the user is 30 minutes, and the time interval between two adjacent blood pressure measurements at night set by the user is also 30 minutes.

[0124] The wearable device 100 is not limited to setting the time interval for blood pressure measurement. It can also receive user operations to set other blood pressure measurement strategies, which is not limited in this application.

[0125] Afterwards, the wearable device 100 can receive the user's input operation (such as a single click) for the start blood pressure measurement option in the user interface 520. In response to the user's input operation, the wearable device 100 can save the blood pressure measurement plan set by the user and start measuring the user's blood pressure when the conditions of the blood pressure measurement plan are met.

[0126] For another example, as shown in FIG5C , the wearable device 100 may receive a user input operation (e.g., a click) for option 502 in the user interface 510. In response to the user input operation, the wearable device 100 may display the user interface 530 shown in FIG5D . The user interface 530 shows a portion of a blood pressure measurement strategy of a blood pressure measurement scheme. The blood pressure measurement scheme may be preset. For example, the preset blood pressure measurement scheme includes the time interval between two adjacent blood pressure measurements during the day and the time interval between two adjacent blood pressure measurements at night. For example, the time interval between two adjacent blood pressure measurements during the day is 30 minutes, and the time interval between two adjacent blood pressure measurements at night is also 30 minutes.

[0127] Afterwards, the wearable device 100 can receive the user's input operation (such as a single click) for the start blood pressure measurement option in the user interface 530. In response to the user's input operation, the wearable device 100 can save the preset blood pressure measurement plan and start measuring the user's blood pressure when the conditions of the preset blood pressure measurement plan are met.

[0128] It should be noted that FIG. 5A to FIG. 5D only show schematic diagrams of a manually created blood pressure measurement plan. The user may manually create a blood pressure measurement plan in other ways, and this application does not limit this.

[0129] As can be seen from Figures 5A to 5D, the blood pressure measurement plans all need to be manually created or manually set by the user to take effect, which is cumbersome for the user to operate. In addition, the blood pressure measurement plans manually created or manually set by the user may not meet the user's needs, resulting in a poor user experience.

[0130] Based on this, the present application provides a method for generating a blood pressure measurement plan. The wearable device 100 can automatically generate a blood pressure measurement plan based on one or more of user information, physiological data, and device status. This eliminates the need for the user to manually create a blood pressure measurement plan, saving user effort.

[0131] A blood pressure measurement plan may include one or more blood pressure measurement strategies, which may include but are not limited to: the start time of the blood pressure measurement, the end time of the blood pressure measurement, the duration of the blood pressure measurement, the number of blood pressure measurements within the duration of the blood pressure measurement, the time interval between two adjacent blood pressure measurements within the duration of the blood pressure measurement, the total number of blood pressure measurements, etc.

[0132] The cycle of the blood pressure measurement scheme can be a day (24 hours) or other cycles, which is not limited in this application.

[0133] User information includes but is not limited to one or more of the following: gender, age, height, weight, whether to smoke, whether to drink, medical history, whether to take medication, living habits and other information.

[0134] Physiological data includes but is not limited to one or more of the following: heart rate, blood pressure, arteriosclerosis, blood sugar, etc.

[0135] The device status includes but is not limited to one or more of the following: remaining battery power, device temperature, etc.

[0136] Wearable device 100 can determine the user's hypertension risk based on user information, physiological data, device status, and other information. It can also determine a blood pressure measurement plan based on the user's hypertension risk. Different blood pressure measurement plans are used for different hypertension risks.

[0137] Optionally, the blood pressure measurement plan may refer to a blood pressure measurement plan within one day (24 hours).

[0138] Optionally, different users have different user information, physiological data, and device status, and the wearable device 100 may obtain different blood pressure measurement solutions.

[0139] For example, when it is determined that the user's hypertension risk is high, the measurement mode of the blood pressure measurement solution obtained by the wearable device 100 may be a high-frequency measurement mode.

[0140] When it is determined that the user's hypertension risk is low, the measurement mode of the blood pressure measurement solution obtained by the wearable device 100 may be a low-frequency measurement mode.

[0141] The total number of blood pressure measurements in the high-frequency measurement mode is greater than the total number of blood pressure measurements in the low-frequency measurement mode.

[0142] Optionally, the total number of blood pressure measurements may refer to the total number of blood pressure measurements within one day (24 hours).

[0143] In other embodiments, the high-frequency measurement mode and the low-frequency measurement mode may also be measurement modes within a certain time period.

[0144] For example, when it is determined that the user's hypertension risk is high only in the first time period, the wearable device 100 can measure the user's blood pressure in the high-frequency measurement mode only in the first time period, and measure the user's blood pressure in the low-frequency measurement mode in non-first time periods.

[0145] For example, when it is determined that the user's hypertension risk is high only between 8 a.m. and 12 a.m., and the user's hypertension risk is low between 0 a.m. and 8 a.m. and between 12 a.m. and 12 p.m., the wearable device 100 can measure the user's blood pressure in a high-frequency measurement mode only between 8 a.m. and 12 a.m., and measure the user's blood pressure in a low-frequency measurement mode between 0 a.m. and 8 a.m. and between 12 a.m. and 12 p.m.

[0146] In some embodiments, the wearable device 100 can further classify the high risk of hypertension into different high risk levels, and enable different measurement modes based on different high risk levels.

[0147] For example, high risk can be further divided into first-level risk and second-level risk, where first-level risk is greater than second-level risk. High risk is not limited to two levels, and can also be divided into more levels, which is not limited in this application.

[0148] When it is determined that the user's hypertension risk in the first time period is a first risk and the hypertension risk in the second time period is a second risk, the wearable device 100 may measure the user's blood pressure in the first time period using the first high-frequency measurement mode and in the second time period using the second high-frequency measurement mode. The total number of blood pressure measurements in the first high-frequency measurement mode is greater than the total number of blood pressure measurements in the second high-frequency measurement mode.

[0149] For example, when it is determined that the user's hypertension risk is a first level risk between 8 a.m. and 10 a.m., the user's hypertension risk is a second level risk between 10 a.m. and 12 a.m., and the user's hypertension risk is a low risk between 0 a.m. and 8 a.m. and between 12 a.m. and 12 p.m., the wearable device 100 can measure the user's blood pressure in a first high-frequency measurement mode between 8 a.m. and 10 a.m., measure the user's blood pressure in a second high-frequency measurement mode between 10 a.m. and 12 a.m., and measure the user's blood pressure in a low-frequency measurement mode between 0 a.m. and 8 a.m. and between 12 a.m. and 12 p.m.

[0150] In some embodiments, the wearable device 100 can determine the start time of blood pressure measurement based on the user's living habits.

[0151] The wearable device 100 can determine the user's living habits based on the collected user data, such as the user's historical travel data, historical riding records, and other user data, and then determine the start time of blood pressure measurement based on the user's living habits to avoid disturbing the user's daily activities.

[0152] For example, based on the collected user data, the wearable device 100 can determine that the user is on his way to work between 7:00 and 8:30 am. Then, the start time of the blood pressure measurement in the blood pressure measurement plan determined by the wearable device 100 can be avoided between 7:00 and 8:30 am.

[0153] Optionally, after the wearable device 100 determines the blood pressure measurement plan, the wearable device 100 may prompt the user to view the details of the blood pressure measurement plan and confirm whether to save and use the blood pressure measurement plan.

[0154] 6A-6B are schematic diagrams showing the wearable device 100 recommending a blood pressure measurement plan to a user.

[0155] After the wearable device 100 determines the blood pressure measurement plan, the wearable device 100 may prompt the user to view the details of the blood pressure measurement plan to prompt the user whether to save and use the blood pressure measurement plan.

[0156] As shown in FIG6A , the wearable device 100 may display a prompt bar 601, which includes a prompt message “Do you want to save and use the blood pressure measurement plan?” The prompt bar 601 is used to prompt the user to view the details of the blood pressure measurement plan.

[0157] Among them, the prompt bar 601 includes option 602, option 603 and option 604. Among them, the wearable device 100 can receive the user's input operation (such as a single click) for option 602, and in response to the user's input operation, the wearable device 100 can display the details of blood pressure measurement solution 1. The wearable device 100 can also receive the user's input operation (such as a single click) for option 603, and in response to the user's input operation, the wearable device 100 can display the details of blood pressure measurement solution 2. The wearable device 100 can also receive the user's input operation (such as a single click) for option 604, and in response to the user's input operation, the wearable device 100 can display the details of blood pressure measurement solution 3.

[0158] Exemplarily, as shown in FIG6A , the wearable device 100 may receive a user input operation (e.g., a click) for option 604 in the prompt bar 601. In response to the user's input operation, the wearable device 100 may display the prompt bar 605 shown in FIG6B , in which the details of the blood pressure measurement plan three are shown. For example, the details of the blood pressure measurement plan three may include: the time interval between two adjacent blood pressure measurements during the day is 30 minutes, and the time interval between two adjacent blood pressure measurements at night is also 30 minutes. The user can view the details of the blood pressure measurement plan three in the prompt bar 605. The prompt bar 605 also includes a confirmation option and a modification option. Among them, the user can save the blood pressure measurement plan three by confirming the option. The user can also modify the blood pressure measurement plan three by modifying the option and then save the modified blood pressure measurement plan three.

[0159] The wearable device 100 prompts the user to change the blood pressure measurement plan based on the remaining power.

[0160] In some embodiments, after the wearable device 100 determines and saves the blood pressure measurement plan, before the wearable device 100 uses the blood pressure measurement plan, the wearable device 100 can determine the minimum power required for the blood pressure measurement plan, and compare the minimum power required for the blood pressure measurement plan with the remaining power of the wearable device 100 to determine whether the saved blood pressure measurement plan needs to be changed, so as to avoid the situation where the wearable device 100 is shut down and unable to measure blood pressure due to low power.

[0161] FIG7 is a flow chart showing a method in which the wearable device 100 prompts the user to change the blood pressure measurement scheme based on the remaining battery power.

[0162] S701: The wearable device 100 obtains one or more of the user's information, physiological data, and device status.

[0163] User information includes but is not limited to one or more of the following: gender, age, height, weight, whether to smoke, whether to drink, medical history, whether to take medication, etc.

[0164] Physiological data includes but is not limited to one or more of the following: heart rate, blood pressure, arteriosclerosis, blood sugar, etc.

[0165] The device status includes but is not limited to one or more of the following: remaining battery power, device temperature, etc.

[0166] Wearable device 100 can determine the user's hypertension risk based on user information, physiological data, device status, and other information. It can also determine a blood pressure measurement plan based on the user's hypertension risk. Different blood pressure measurement plans are used for different hypertension risks.

[0167] S702: The wearable device 100 determines a blood pressure measurement plan based on one or more of the user information, physiological data, and device status.

[0168] A blood pressure measurement plan may include one or more blood pressure measurement strategies, which may include but are not limited to: the start time of the blood pressure measurement, the end time of the blood pressure measurement, the duration of the blood pressure measurement, the number of blood pressure measurements within the duration of the blood pressure measurement, the time interval between two adjacent blood pressure measurements within the duration of the blood pressure measurement, the total number of blood pressure measurements, etc.

[0169] Optionally, the blood pressure measurement plan may refer to a blood pressure measurement plan within one day (24 hours).

[0170] Optionally, different users have different user information, physiological data, and device status, and the wearable device 100 may obtain different blood pressure measurement solutions.

[0171] For example, when it is determined that the user's hypertension risk is high, the measurement mode of the blood pressure measurement solution obtained by the wearable device 100 may be a high-frequency measurement mode.

[0172] When it is determined that the user's hypertension risk is low, the measurement mode of the blood pressure measurement solution obtained by the wearable device 100 may be a low-frequency measurement mode.

[0173] The total number of blood pressure measurements in the high-frequency measurement mode is greater than the total number of blood pressure measurements in the low-frequency measurement mode.

[0174] In other embodiments, the blood pressure measurement scheme may also be determined by other devices (such as mobile phones or servers) that establish a communication connection with the wearable device 100 and then sent to the wearable device 100.

[0175] S703: The wearable device 100 determines the minimum power level based on the blood pressure measurement solution.

[0176] The minimum power may be the minimum power required to complete the total number of blood pressure measurements in a blood pressure measurement regimen in one day.

[0177] After the wearable device 100 obtains the blood pressure measurement plan, the wearable device 100 can estimate the minimum power required to complete the total number of blood pressure measurements in a day based on the blood pressure measurement plan to meet the blood pressure measurement plan requirements of high-frequency blood pressure start-up measurements.

[0178] Optionally, the wearable device 100 may obtain the minimum power required to complete the total number of blood pressure measurements in a day based on the average power required to complete one blood pressure measurement and the estimated total number of blood pressure measurements in the blood pressure measurement scheme.

[0179] S704: The wearable device 100 determines whether the minimum power level is greater than the remaining power level of the wearable device 100.

[0180] The wearable device 100 may obtain the remaining power of the wearable device 100 and determine whether the minimum power is greater than the remaining power of the wearable device 100 .

[0181] If it is determined that the lowest power level is greater than the remaining power level of the wearable device 100 , S705 is executed.

[0182] If it is determined that the lowest power level is less than the remaining power level of the wearable device 100 , S706 is executed.

[0183] S705: The wearable device 100 saves the blood pressure measurement plan.

[0184] When it is determined that the minimum power is greater than the remaining power of the wearable device 100, the remaining power of the wearable device 100 can complete the minimum power required for the total number of blood pressure measurements in the blood pressure measurement plan within one day, and the wearable device 100 saves the blood pressure measurement plan.

[0185] In some embodiments, before the wearable device 100 saves the blood pressure measurement plan, the wearable device 100 may display the user interface shown in Figures 6A-6B to prompt the user to review the blood pressure measurement plan. The user may also proactively modify the blood pressure measurement plan and save the modified blood pressure measurement plan.

[0186] S706: The wearable device 100 prompts the user to charge and determines whether to charge.

[0187] When it is determined that the minimum power is less than the remaining power of the wearable device 100, the remaining power of the wearable device 100 cannot complete the minimum power required for the total number of blood pressure measurements in the blood pressure measurement plan within one day, and the wearable device 100 can prompt the user to charge the wearable device 100.

[0188] If it is determined that charging is already underway, S705 is executed.

[0189] If it is determined that the battery is not charged, S707 is executed.

[0190] For example, if it is determined that the minimum power level is less than the remaining power of the wearable device 100, the wearable device 100 may display the prompt message 801 shown in FIG8A . The prompt message 801 includes the text message "Battery is too low, do you want to charge?" The prompt message 801 is used to prompt the user to charge the wearable device 100 in a timely manner. The prompt message 801 also includes a confirmation option and a cancel option. The user can confirm to charge the wearable device 100 by selecting the confirmation option, or confirm not to charge the wearable device 100 by selecting the cancel option.

[0191] S707: The wearable device 100 prompts the user to change the blood pressure measurement plan and determines whether the user agrees to change the blood pressure measurement plan.

[0192] When it is determined that the wearable device 100 is not charged, the wearable device 100 may prompt the user to change the blood pressure measurement scheme and determine whether the user agrees to change the blood pressure measurement scheme.

[0193] Among them, adjusting the blood pressure measurement scheme may refer to reducing the total number of blood pressure measurements in the blood pressure measurement scheme to save power consumption of the wearable device 100 so that the remaining power of the wearable device 100 can complete blood pressure measurements within a day.

[0194] In one possible implementation, the wearable device 100 can automatically reduce the total number of blood pressure measurements in the blood pressure measurement scheme based on the remaining power of the wearable device 100, so that the remaining power of the wearable device 100 can complete the total number of blood pressure measurements in the modified blood pressure measurement scheme.

[0195] In other possible implementations, the wearable device 100 may receive a user operation to reduce the total number of blood pressure measurements in the blood pressure measurement scheme, so that the remaining power of the wearable device 100 can complete the total number of blood pressure measurements in the modified blood pressure measurement scheme.

[0196] In some embodiments, after the wearable device 100 displays the prompt message 801, the wearable device 100 may determine whether the wearable device 100 is charging. If it is detected that the device is not charging within the first time period (for example, one minute), the wearable device 100 may display the prompt message 802 shown in Figure 8B. The prompt message 802 includes the text message "The current battery is too low. Do you accept the adjustment of the blood pressure measurement plan?" The prompt message 802 is used to prompt the user to accept the adjustment of the blood pressure measurement plan to reduce the number of blood pressure measurements. The prompt message 802 also includes a yes option and a no option. Among them, the user can confirm to accept the adjustment of the blood pressure measurement plan through the yes option, and the user can also refuse to accept the adjustment of the blood pressure measurement plan through the no option.

[0197] If the user agrees to change the blood pressure measurement plan, execute S708.

[0198] If the user does not agree to change the blood pressure measurement plan, execute S709.

[0199] S708: The wearable device 100 saves the modified blood pressure measurement solution.

[0200] If the user agrees to change the blood pressure measurement plan, the wearable device 100 can save the modified blood pressure measurement plan.

[0201] S709: The wearable device 100 prompts the user to enter the low power consumption mode and determines whether the user agrees to enter the low power consumption mode.

[0202] If the user does not agree to change the blood pressure measurement scheme, the wearable device 100 can prompt the user to enter the low power mode to save power consumption and electricity of the wearable device 100. The wearable device 100 needs to determine whether the user agrees to enter the low power mode.

[0203] Among them, controlling the wearable device 100 to enter the low power consumption mode may refer to shutting down some or all energy-consuming operations on the wearable device 100 that are not related to blood pressure monitoring. For example, energy-consuming operations may include but are not limited to heart rate monitoring functions, motion data recording functions, etc.

[0204] If the user agrees that the wearable device 100 enters the low power consumption mode, S705 is executed.

[0205] If the user does not agree that the wearable device 100 enters the low power consumption mode, S710 is executed.

[0206] For example, as shown in FIG8B , the wearable device 100 may receive a user input operation (eg, a single click) for a no option in the prompt information 802 . In response to the user's input operation, the wearable device 100 does not adjust the blood pressure measurement solution.

[0207] After the user chooses not to adjust the blood pressure measurement scheme, the wearable device 100 may display the prompt message 803 shown in FIG8C , which includes the prompt message 803. The prompt message 803 includes the text message "The current battery is too low, do you want to enter low power mode?" The prompt message 803 is used to prompt the user to control the wearable device 100 to enter low power mode to save power consumption of the wearable device 100. The prompt message 803 also includes a yes option and a no option. The user can control the wearable device 100 to enter low power mode by using the yes option, and the user can also not control the wearable device 100 to enter low power mode by using the no option.

[0208] S710: The wearable device 100 prompts the user that the battery is too low and may shut down at any time.

[0209] If the user does not agree that the wearable device 100 enters the low power consumption mode, the wearable device 100 may prompt the user that the battery is too low and may shut down at any time.

[0210] For example, as shown in FIG8C , the wearable device 100 may receive a user input operation (eg, a single click) for a no option in the prompt information 803 . In response to the user's input operation, the wearable device 100 does not enter the low power consumption mode.

[0211] In response to the user's input operation for the no option in the prompt information 803, the wearable device 100 can display the prompt information 804 shown in Figure 8D. The prompt information 804 may include the text message "The battery is too low and may shut down at any time. Please charge in time!" to remind the user that the battery of the wearable device 100 is too low.

[0212] Optionally, the embodiment of Figure 7 can be to determine whether the power of the wearable device 100 is too low before starting to measure blood pressure within a day, so as to select an appropriate strategy to save the power consumption of the wearable device 100 and increase the usage time of the remaining power of the wearable device 100.

[0213] The wearable device 100 uses a blood pressure measurement solution and displays a single blood pressure measurement result.

[0214] After obtaining the blood pressure measurement plan, the wearable device 100 can monitor the user's blood pressure throughout the day based on the blood pressure measurement plan.

[0215] Based on the above description, it can be seen that the blood pressure measurement plan may include one or more blood pressure measurement strategies, which may include but are not limited to: the start time of the blood pressure measurement, the end time of the blood pressure measurement, the duration of the blood pressure measurement, the number of blood pressure measurements within the duration of the blood pressure measurement, the time interval between two adjacent blood pressure measurements within the duration of the blood pressure measurement, the total number of blood pressure measurements, etc.

[0216] In some embodiments, before the wearable device 100 uses the blood pressure measurement solution to measure blood pressure, it is necessary to determine whether the current user status meets the blood pressure measurement conditions. If the blood pressure measurement conditions are met, the wearable device 100 will begin measuring the user's blood pressure. If the blood pressure measurement conditions are not met, the wearable device 100 will not measure the user's blood pressure until the blood pressure measurement conditions are met and then begin measuring the user's blood pressure.

[0217] FIG9 shows a flow chart of a method for measuring a user's blood pressure using the wearable device 100 .

[0218] S901: The wearable device 100 obtains the current user status.

[0219] The current user status may include but is not limited to one or more of the following: motion data, physiological data, etc.

[0220] Motion data can include acceleration data, angular velocity data, and cumulative step count, etc.

[0221] Physiological data may include real-time heart rate and nighttime resting heart rate, etc. Nighttime resting heart rate may be an average value of heart rates measured by the wearable device 100 at night.

[0222] S902: The wearable device 100 determines whether the current user status meets the blood pressure measurement conditions.

[0223] The blood pressure measurement conditions may include but are not limited to one or more of the following: the user is in a stationary state, and the difference between the real-time heart rate and the nighttime resting heart rate is within a preset range.

[0224] Wearable device 100 can collect motion data using a motion sensor. Motion sensors may include, but are not limited to, accelerometers, gyroscopes, and the like. The motion sensor can collect motion data or motion trajectories. Wearable device 100 can determine whether the user is stationary based on the motion data or motion trajectories.

[0225] Generally, users are in a static state, with little activity and a relatively stable real-time heart rate. If the difference between the real-time heart rate and the resting heart rate at night is within a preset range, the user can be determined to be in a static state. Wearable device 100 can determine whether the user is in a static state based on the real-time heart rate collected by the PPG sensor.

[0226] If it is determined that the current user status meets the blood pressure measurement conditions, S903 is executed.

[0227] If it is determined that the current user status does not meet the blood pressure measurement condition, S901 is executed.

[0228] In this way, before measuring blood pressure, the wearable device 100 can determine whether the blood pressure measurement conditions are met. If the blood pressure measurement conditions are met, the wearable device 100 will start measuring the user's blood pressure, which can improve the accuracy of blood pressure measurement. Because when the blood pressure measurement conditions are not met, the user may be in a non-stationary state, such as running or exercising, and the blood pressure result of the wearable device 100 may be inaccurate.

[0229] S903: The wearable device 100 determines whether the time difference between the last blood pressure measurement time and the current time satisfies a preset time interval.

[0230] When it is determined that the current user status meets the blood pressure measurement condition, before starting to measure the blood pressure, the wearable device 100 can determine whether the time difference between the last blood pressure measurement time and the current time meets the preset time interval.

[0231] If it is determined that the time difference between the last blood pressure measurement time and the current time satisfies the preset time interval, S904 is executed.

[0232] If it is determined that the time difference between the last blood pressure measurement time and the current time does not meet the preset time interval, S901 is executed.

[0233] Based on the above description, it can be seen that the blood pressure measurement scheme determined by the wearable device 100 may include one or more blood pressure measurement strategies. The blood pressure measurement strategy may include but is not limited to: the start time of the blood pressure measurement, the end time of the blood pressure measurement, the duration of the blood pressure measurement, the number of blood pressure measurements within the duration of the blood pressure measurement, the time interval between two adjacent blood pressure measurements within the duration of the blood pressure measurement, the total number of blood pressure measurements, etc.

[0234] Before starting to measure blood pressure, the wearable device 100 needs to determine whether the time difference between the last blood pressure measurement time and the current time is a preset time interval specified in the blood pressure measurement scheme.

[0235] The preset time intervals for different blood pressure measurement durations are different. For example, between 9:00 AM and 12:00 AM, the preset time interval may be 20 minutes. Between 9:00 PM and 9:00 AM, the preset time interval may be 30 minutes.

[0236] Before starting to measure blood pressure, the wearable device 100 can determine whether the time difference between the last blood pressure measurement and the current time satisfies a preset time interval. If the preset time interval is satisfied, the wearable device 100 will start measuring the user's blood pressure again to avoid frequent blood pressure measurements.

[0237] S904: The wearable device 100 measures the user's blood pressure and saves the blood pressure measurement result.

[0238] When it is determined that the time difference between the last blood pressure measurement time and the current time satisfies the preset time interval, the wearable device 100 can start measuring the user's blood pressure and save the blood pressure measurement result.

[0239] In some embodiments, in order to ensure the accuracy of blood pressure measurement, the wearable device 100 can display a prompt message to prompt the user to measure blood pressure.

[0240] 10A-10E are schematic diagrams showing the wearable device 100 displaying prompt information to prompt the user to measure blood pressure.

[0241] For example, as shown in FIG10A , when the wearable device 100 starts measuring blood pressure, in order to ensure the accuracy of the blood pressure measurement results, the wearable device 100 may display the user interface 710 shown in FIG10A . The user interface 710 displays a prompt message “The blood pressure measurement time has arrived, please remain still and click to start the measurement”. This prompt message is used to remind the user to remain still during the blood pressure measurement process to avoid inaccurate blood pressure measurement results due to exercise. The user interface 710 also includes a measurement reminder option and a skip option. The user can view the precautions for measuring blood pressure through the measurement reminder option, and the user can also skip the precautions for measuring blood pressure and start measuring blood pressure directly.

[0242] For example, as shown in FIG10A , the wearable device 100 may receive a user input operation (e.g., a click) for the measurement reminder option in the user interface 710. In response to the user input operation, the wearable device 100 may display the user interface 720 shown in FIG10B . The user interface 720 includes a prompt message "When measuring, please pay attention to wearing the watch flush with the heart and do not press the heart." This prompt message is used to remind the user of the correct measurement posture. The user interface 720 includes a timing option 7201, which is used to prompt the user to lift the watch to a position flush with the heart within a preset time.

[0243] After the countdown time displayed on the wearable device 100 reaches 0, the wearable device 100 can start measuring the user's blood pressure.

[0244] Optionally, while wearable device 100 is measuring a user's blood pressure, wearable device 100 may display user interface 730 shown in FIG10C . User interface 730 includes a prompt message "Please remain still during blood pressure measurement" to remind the user to remain still during the measurement to avoid inaccurate blood pressure measurement results due to movement. User interface 730 also includes a cancel measurement option, which allows the user to stop the blood pressure measurement.

[0245] In some embodiments, after the wearable device 100 obtains a blood pressure monitoring value, the wearable device 100 may display the user interface 740 shown in FIG10D . The user interface 740 includes the blood pressure measurement value, which may include a high pressure and a low pressure. For example, the high pressure may be 130 mmHg and the low pressure may be 80 mmHg. In some embodiments, the user interface 740 may also include a pulse rate, for example, a pulse rate of 69 beats per minute.

[0246] In some embodiments, after the wearable device 100 obtains a blood pressure monitoring value, the wearable device 100 may further display a user interface 750 shown in FIG10E , which displays detailed information about the blood pressure measurement, such as the user status, the total number of blood pressure measurements, the time interval since the last blood pressure measurement, the time interval until the next blood pressure measurement, etc. For example, the user status shown in FIG10E is a stationary state, the total number of blood pressure measurements is 5, the interval since the last blood pressure measurement is 20 minutes, and the estimated time to start the next blood pressure measurement is also 20 minutes.

[0247] User interface 750 also includes a confirmation option and an optimization blood pressure measurement solution option. The user can use the confirmation option to cause the wearable device 100 to stop displaying user interface 750. The user can also use the optimization blood pressure measurement solution option to proactively modify the blood pressure measurement solution. For details, please refer to the description in the following embodiments, and this application will not elaborate on this further.

[0248] In some embodiments, the wearable device 100 may not display the prompt information shown in Figures 10A-10E and directly start measuring the user's blood pressure to avoid frequently disturbing the user. For example, at night, the wearable device 100 may not display the prompt information shown in Figures 10A-10E. The wearable device 100 may not display the prompt information and automatically measure the user's blood pressure to avoid disturbing the user's rest.

[0249] In some embodiments, the wearable device 100 can measure the user's blood pressure and obtain the blood pressure measurement result. Before saving the blood pressure measurement result, the wearable device 100 needs to determine whether the current user status meets the blood pressure measurement conditions. If the blood pressure measurement conditions are met, the wearable device 100 can directly save the blood pressure measurement result. If the blood pressure measurement conditions are not met, the wearable device 100 can determine a blood pressure compensation value based on the current user status, revise the blood pressure measurement result based on the blood pressure compensation value, and save the revised blood pressure measurement result.

[0250] FIG11 shows a flow chart of another method for measuring a user's blood pressure using a wearable device 100 .

[0251] S1101: The wearable device 100 determines whether the time difference between the last blood pressure measurement time and the current time satisfies a preset time interval.

[0252] Before starting to measure blood pressure, the wearable device 100 needs to determine whether the time difference between the last blood pressure measurement time and the current time satisfies a preset time interval.

[0253] If it is determined that the time difference between the last blood pressure measurement time and the current time satisfies the preset time interval, S1102 is executed.

[0254] If it is determined that the time difference between the last blood pressure measurement time and the current time does not meet the preset time interval, the blood pressure measurement is terminated without further measurement until the time difference between the last blood pressure measurement time and the current time meets the preset time interval.

[0255] Based on the above description, it can be seen that the blood pressure measurement scheme determined by the wearable device 100 may include one or more blood pressure measurement strategies. The blood pressure measurement strategy may include but is not limited to: the start time of the blood pressure measurement, the end time of the blood pressure measurement, the duration of the blood pressure measurement, the number of blood pressure measurements within the duration of the blood pressure measurement, the time interval between two adjacent blood pressure measurements within the duration of the blood pressure measurement, the total number of blood pressure measurements, etc.

[0257] The preset time intervals for different blood pressure measurement durations are different. For example, between 9:00 AM and 12:00 AM, the preset time interval may be 20 minutes. Between 9:00 PM and 9:00 AM, the preset time interval may be 30 minutes.

[0258] Before starting to measure blood pressure, the wearable device 100 can determine whether the time difference between the last blood pressure measurement and the current time satisfies a preset time interval. If the preset time interval is satisfied, the wearable device 100 will start measuring the user's blood pressure again to avoid frequent blood pressure measurements.

[0259] S1102: The wearable device 100 measures blood pressure and obtains a blood pressure measurement result.

[0260] When it is determined that the time difference between the last blood pressure measurement time and the current time satisfies the preset time interval, the wearable device 100 can start measuring the blood pressure and obtain the blood pressure measurement result.

[0263] The wearable device 100 obtains the current user status and determines whether the current user status meets the blood pressure measurement conditions.

[0264] For the introduction of S1103-S1104, please refer to the description in S901-S902, and this application will not go into details here.

[0265] If it is determined that the current user status meets the blood pressure measurement conditions, S1105 is executed.

[0266] If it is determined that the current user status does not meet the blood pressure measurement conditions, S1106 is executed.

[0267] S1105: The wearable device 100 saves the blood pressure measurement result.

[0268] When it is determined that the current user status meets the blood pressure measurement conditions, the wearable device 100 can directly save the blood pressure measurement result.

[0269] S1106: The wearable device 100 obtains a blood pressure compensation value based on the current user status.

[0270] If it is determined that the current user state does not meet the blood pressure measurement conditions, the wearable device 100 can obtain a blood pressure compensation value based on the current user state. Different blood pressure compensation values ​​are determined for different user states.

[0271] S1107: The wearable device 100 obtains a corrected blood pressure measurement value based on the blood pressure compensation value and the blood pressure measurement value.

[0272] S1108: The wearable device 100 saves the corrected blood pressure measurement value.

[0273] After determining whether the current user state meets the blood pressure measurement conditions, the wearable device 100 can obtain a blood pressure compensation value based on the current user state and correct the blood pressure measurement value based on the blood pressure compensation value to obtain a corrected blood pressure measurement value. This eliminates the impact of user states that do not meet the blood pressure measurement conditions on the blood pressure measurement value.

[0274] After obtaining the corrected blood pressure measurement value, the wearable device 100 can save the corrected blood pressure measurement value.

[0275] As can be seen from the embodiment of Figure 7, after the wearable device 100 determines the blood pressure measurement plan, before the wearable device 100 uses the blood pressure measurement plan, the wearable device 100 can determine the minimum power required for the blood pressure measurement plan. When the remaining power of the wearable device 100 is too low, the user can charge the wearable device 100 in time to avoid the situation where the wearable device 100 is shut down and unable to measure blood pressure due to low power.

[0276] In some embodiments, before measuring blood pressure, the wearable device 100 needs to detect whether it is in a wearing state. If it is not in a wearing state, the user is promptly prompted to wear the wearable device 100 and start measuring blood pressure.

[0277] FIG12 shows a flow chart of another method for measuring a user's blood pressure using the wearable device 100 .

[0279] S1202: The wearable device 100 determines whether the remaining power of the wearable device 100 meets the minimum power required by the blood pressure measurement solution.

[0280] The wearable device 100 can determine whether the wearable device 100 is worn on the user's wrist. If it is not worn on the user's wrist, the wearable device 100 determines that it is in an unworn state.

[0281] The wearable device 100 can obtain the remaining power of the wearable device 100 and determine the minimum power required to complete the blood pressure measurement scheme based on the blood pressure measurement scheme.

[0282] The wearable device 100 needs to determine whether the remaining power of the wearable device 100 is greater than the minimum power required by the blood pressure measurement solution.

[0283] If the remaining power of the wearable device 100 is less than the minimum power required for the blood pressure measurement scheme, S1203 is executed.

[0284] If the remaining power of the wearable device 100 is greater than the minimum power required for the blood pressure measurement scheme, S1204 is executed.

[0285] S1203: The wearable device 100 sends a message 1 to the electronic device 200. The message 1 is used to instruct the electronic device 200 to remind the user to charge the wearable device 100 in time.

[0286] When the remaining power of the wearable device 100 is less than the minimum power required by the blood pressure measurement solution, in order to avoid the wearable device 100 being shut down and unable to measure blood pressure due to low power, the wearable device 100 can send message 1 to the electronic device 200 with which it has established a communication connection. Message 1 is used to instruct the electronic device 200 to remind the user to charge the wearable device 100 in time.

[0287] After receiving the message 1 sent by the wearable device 100, the electronic device 200 can prompt the user to charge the wearable device 100 in time.

[0288] Optionally, the prompt method may include but is not limited to: vibration, voice, pop-up window, flashing light, etc.

[0289] Optionally, the electronic device 200 may adopt different prompting methods based on different usage states.

[0290] For example, when the electronic device 200 is in use, the electronic device 200 can prompt the user to charge the wearable device 100 in time through a pop-up window.

[0291] For example, as shown in FIG13A , the electronic device 200 may display a prompt bar 1301 above the main interface, wherein the prompt bar 1301 includes a prompt message “Battery is too low, please charge the wearable device 100 in time.” The prompt bar 1301 is used to prompt the user to charge the wearable device 100 in time.

[0295] S1204: The wearable device 100 determines whether the current user status meets the blood pressure measurement conditions.

[0296] If the remaining battery level of the wearable device 100 is greater than the minimum battery level required by the blood pressure measurement solution, the wearable device 100 determines whether the current user status satisfies the blood pressure measurement conditions. If the current user status satisfies the blood pressure measurement conditions, the wearable device 100 begins measuring the user's blood pressure.

[0297] For the introduction of S1204, please refer to the description in S901-S902, and this application will not go into details here.

[0298] If it is determined that the current user status meets the blood pressure measurement conditions, S1205 is executed.

[0299] When it is determined that the current user status does not meet the blood pressure measurement condition, the user status is continuously monitored until the user status meets the blood pressure measurement condition.

[0300] S1205: The wearable device 100 determines whether it is time to measure blood pressure after the first preset time.

[0301] If it is determined that the current user state meets the blood pressure measurement conditions, before measuring the blood pressure, the wearable device 100 can determine whether the blood pressure measurement time has arrived after the first preset time, so that the electronic device 200 can remind the user to wear the wearable device 100 in advance and in time to measure the blood pressure.

[0302] When it is determined that the blood pressure measurement time arrives after the first preset time, S1206 is executed, so that the electronic device 200 can remind the user to wear the wearable device 100 in advance and in time to measure the blood pressure.

[0303] If it is determined that the blood pressure measurement time has not arrived after the first preset time, S1204 is executed.

[0304] S1206. The wearable device 100 sends a second message to the electronic device 200. The second message is used to instruct the electronic device 200 to remind the user to wear the wearable device 100 in time.

[0305] When the wearable device 100 determines that the blood pressure measurement time has not arrived after the first preset time, in order to enable the electronic device 200 to remind the user to wear the wearable device 100 in advance and in time, the wearable device 100 can send message 2 to the electronic device 200 with which a communication connection is established. Message 2 is used to instruct the electronic device 200 to remind the user to wear the wearable device 100 in time.

[0306] After receiving the second message sent by the wearable device 100, the electronic device 200 may prompt the user to wear the wearable device 100 in a timely manner.

[0307] Optionally, the prompt method may include but is not limited to: vibration, voice, pop-up window, flashing light, etc.

[0308] Optionally, the electronic device 200 may adopt different prompting methods based on different usage states.

[0309] For example, when the electronic device 200 is in use, the electronic device 200 can prompt the user to wear the wearable device 100 in time through a pop-up window.

[0310] 13C , the electronic device 200 may display a prompt bar 1303 above the main interface, wherein the prompt bar 1303 includes a prompt message "Blood pressure will be measured soon, please wear the wearable device 100 in time." The prompt bar 1301 is used to remind the user to wear the wearable device 100 in time.

[0311] 13D , the electronic device 200 may display a prompt message 1304 in the pull-down notification bar, including the prompt message "Blood pressure will be measured soon, please wear the wearable device 100 in time." The prompt message 1304 is used to remind the user to wear the wearable device 100 in time.

[0312] 13C and 13D , the electronic device 200 displays prompt information to prompt the user to wear the wearable device 100 in time. The electronic device 200 can also prompt the user to wear the wearable device 100 in time in other ways, which will not be repeated in this embodiment of the present application.

[0313] For another example, when the electronic device 200 is not in use, the electronic device 200 can prompt the user to wear the wearable device 100 in time through one or more methods such as vibration, voice, flashing lights, etc.

[0314] After the wearable device 100 completes a cycle of blood pressure measurement using the blood pressure measurement solution, it displays the blood pressure measurement results within the cycle.

[0315] For example, 24 hours may be one cycle.

[0316] 14A-14D are schematic diagrams showing the wearable device 100 or the electronic device 200 displaying blood pressure measurement results within a cycle.

[0317] Exemplarily, after the wearable device 100 completes a cycle of blood pressure measurement, the wearable device 100 may display the user interface 1410 shown in FIG14A . The user interface 1410 includes the blood pressure measurement results within a cycle. For example, the average high pressure within 24 hours is 125 mmHg, and the average low pressure within 24 hours is 70 mmHg. The average high pressure during the day is 130 mmHg, and the average low pressure during the day is 75 mmHg. The average high pressure at night is 110 mmHg, and the average low pressure at night is 65 mmHg. The user interface 1410 also shows a prompt message "Please see the mobile phone for detailed report", and the user can view the detailed information of the blood pressure measurement results within a cycle on the electronic device 200.

[0318] For example, FIG14B shows a user interface 1420 on the electronic device 200 displaying details of a blood pressure measurement cycle. As shown in FIG14B , the user interface 1420 includes the bedtime and wake-up time, as well as a dynamic blood pressure trend graph for the cycle. The bedtime may be 8:30 p.m. on October 11, 2023. The wake-up time may be 8:30 a.m. on October 12, 2023. The dynamic blood pressure trend graph may display the blood pressure change trend for the cycle. The user interface 1420 also includes 50 blood pressure measurements, an average high blood pressure of 125 mmHg and an average low blood pressure of 70 mmHg for the cycle (e.g., 24 hours). The average high blood pressure during the daytime during the cycle (e.g., 24 hours) is 130 mmHg, and the average low blood pressure during the daytime is 75 mmHg. The average high blood pressure during the nighttime during the cycle (e.g., 24 hours) is 110 mmHg, and the average low blood pressure during the nighttime is 65 mmHg. The diurnal blood pressure variation pattern within the cycle (e.g., 24 hours) is a dipper-shaped rhythm. Based on the blood pressure measurement results within a cycle, the user interface 1400 also displays interpretations and suggestions: Your blood pressure level is within the normal range and your circadian rhythm is normal. Please continue to pay attention to your blood pressure level.

[0319] In other embodiments, when the wearable device 100 has not completed blood pressure measurement within a cycle, for example, it has only completed multiple blood pressure measurements within a time period, the user can also view the blood pressure detection results within this time period on the wearable device 100 or the electronic device 200.

[0320] For example, as shown in FIG14C , wearable device 100 displays a user interface 1430, which displays the average blood pressure measurement results for a specific time period, such as an average high blood pressure of 125 mmHg and an average low blood pressure of 70 mmHg. User interface 1430 also displays a prompt "See mobile phone for detailed report," allowing the user to view detailed information about the blood pressure measurement results for this specific time period on electronic device 200.

[0321] For example, FIG14D shows a user interface 1440 on the electronic device 200 displaying details of blood pressure measurements within a time period. As shown in FIG14D , the user interface 1440 includes the start time and end time of the blood pressure measurement, as well as a dynamic blood pressure trend graph within this time period. The start time of the blood pressure measurement may be 6:30 a.m. on October 11, 2023. The end time of the blood pressure measurement may be 9:30 a.m. on October 11, 2023. The dynamic blood pressure trend graph can show the trend of blood pressure changes within a time period. The user interface 1440 also includes that the number of blood pressure measurements is 10, and the average high pressure during this time period is 125 mmHg, and the average low pressure is 70 mmHg. Based on the blood pressure measurement results during this time period, the user interface 1440 also displays interpretations and suggestions: During the measurement period, your average blood pressure is 125 / 70 mmHg, which is at a normal level. If you need a complete assessment, please complete the 24-hour full measurement.

[0322] The wearable device 100 modifies the blood pressure measurement scheme based on the historical blood pressure measurement data to obtain an optimized blood pressure measurement scheme.

[0323] In some embodiments, the wearable device 100 can obtain historical blood pressure measurement data within a first period of time (for example, one month) and modify the blood pressure measurement scheme obtained by the wearable device 100 based on the historical blood pressure measurement data within the first period of time.

[0324] Historical blood pressure measurement data includes, but is not limited to, historical blood pressure measurement records and historical blood pressure measurement results. Historical blood pressure measurement records may include, but are not limited to, the start time of the historical blood pressure measurement, the end time of the historical blood pressure measurement, the duration of the historical blood pressure measurement, the number of blood pressure measurements within the duration of the historical blood pressure measurement, the time interval between two adjacent blood pressure measurements within the duration of the historical blood pressure measurement, and the total number of historical blood pressure measurements.

[0325] In one possible implementation, the wearable device 100 may periodically or irregularly modify the blood pressure measurement scheme based on historical blood pressure measurement data to obtain an optimized blood pressure measurement scheme, so that the optimized blood pressure measurement scheme is more consistent with the user's behavioral characteristics.

[0326] In other possible implementations, the wearable device 100 may also receive user operations and modify the blood pressure measurement scheme based on historical blood pressure measurement data to obtain an optimized blood pressure measurement scheme, so that the optimized blood pressure measurement scheme is more consistent with the user's behavioral characteristics.

[0327] For example, when the wearable device 100 determines that the user is a hypertensive user based on historical blood pressure measurement data, the total number of blood pressure measurements in the optimized blood pressure measurement scheme determined by the wearable device 100 can be increased to monitor the user's blood pressure in more detail.

[0328] For another example, when the wearable device 100 determines that the user has normal blood pressure based on historical blood pressure measurement data, the total number of blood pressure measurements in the optimized blood pressure measurement scheme determined by the wearable device 100 can be reduced to reduce the power consumption of the wearable device 100.

[0329] For another example, when the wearable device 100 determines based on historical blood pressure measurement data that the user's blood pressure is high between 9 a.m. and 11 a.m., the total number of blood pressure measurements between 9 a.m. and 11 a.m. in the optimized blood pressure measurement plan determined by the wearable device 100 can be increased to perform more detailed monitoring of the user's blood pressure between 9 a.m. and 11 a.m.

[0330] FIG15 is a flow chart of a method for generating a blood pressure measurement solution provided in this application.

[0331] S1501: The wearable device obtains one or more of user information, physiological data, and device status.

[0332] S1502. The wearable device generates a blood pressure measurement plan based on one or more of the user information, physiological data, and device status. The blood pressure measurement plan includes one or more of the following: the start time of the blood pressure measurement, the end time of the blood pressure measurement, the duration of the blood pressure measurement, the number of blood pressure measurements within the duration of the blood pressure measurement, the time interval between two adjacent blood pressure measurements within the duration of the blood pressure measurement, and the total number of blood pressure measurements.

[0333] S1503: The wearable device obtains the blood pressure measurement value of the user within a blood pressure measurement cycle based on the blood pressure measurement solution.

[0334] For example, a blood pressure measurement cycle may be a 24-hour cycle.

[0335] Through this method, wearable devices can automatically generate blood pressure measurement plans based on the fusion of multiple information, so that the blood pressure measurement plans generated by wearable devices are more in line with user characteristics, which not only saves user operations but also improves the rationality of blood pressure measurement.

[0336] In one possible implementation, user information includes one or more of the following: gender, age, height, weight, smoking history, drinking history, medical history, medication history, and lifestyle habits; physiological data includes one or more of the following: heart rate, blood pressure, arteriosclerosis, and blood sugar; device status includes one or more of the following: remaining power and device temperature.

[0337] In one possible implementation, the wearable device generates a blood pressure measurement plan based on one or more of user information, physiological data, and device status, specifically including: the wearable device determines the user's risk level of hypertension risk based on one or more of user information, physiological data, and device status; the wearable device generates a blood pressure measurement plan based on the user's risk level of hypertension risk.

[0338] Different blood pressure measurement plans are generated for different risk levels of hypertension. For example, the total number of blood pressure measurements determined by a wearable device based on a high risk is greater than the total number of blood pressure measurements determined by a wearable device based on a low risk.

[0339] In some embodiments, the risk level of hypertension risk may refer to the risk level within a certain time period within a blood pressure measurement cycle. For example, if a user's risk level of hypertension risk during the nighttime period is greater than the user's risk level of hypertension risk during the daytime period, then the total number of blood pressure measurements during the nighttime period is greater than the total number of blood pressure measurements during the daytime period.

[0340] In this way, the wearable device can determine the user's risk level of hypertension based on various information, and then generate a blood pressure measurement plan based on the risk level of hypertension.

[0341] In one possible implementation, after the wearable device generates a blood pressure measurement plan, the method also includes: the wearable device displays a first prompt message, the first prompt message is used to prompt the user to view the details of the blood pressure measurement plan; the wearable device receives and responds to the user's first operation on the first option in the first prompt message, and displays a first user interface, in which the details of the blood pressure measurement plan are displayed.

[0342] In this way, after the wearable device automatically generates a blood pressure measurement plan, the wearable device can prompt the user to view the details of the blood pressure measurement plan. In some embodiments, the wearable device can also receive user operations to modify the blood pressure measurement plan.

[0343] In one possible implementation, before the wearable device obtains the blood pressure measurement value of the user within a blood pressure measurement cycle based on the blood pressure measurement scheme, the method also includes: the wearable device obtains the remaining power of the wearable device; when the remaining power of the wearable device is less than a preset power, the wearable device displays a second prompt message, and the second prompt message is used to prompt the user to charge the wearable device, wherein the preset power is the minimum power required for the wearable device to complete the blood pressure measurement within a blood pressure measurement cycle based on the blood pressure measurement scheme; when the wearable device is in a charging state within a first period of time after the second prompt message is displayed, the blood pressure measurement scheme is saved.

[0344] Before the wearable device measures blood pressure based on the automatically generated blood pressure measurement plan, it must determine whether the remaining battery power is sufficient. This prevents the wearable device from shutting down before completing a blood pressure measurement cycle. After the wearable device displays a prompt message and is charging, it can save the blood pressure measurement plan and complete blood pressure measurements within a blood pressure measurement cycle based on the blood pressure measurement plan.

[0345] In one possible implementation, the method also includes: when the wearable device is not in a charging state within a first period of time after displaying the second prompt information, the wearable device displays a third prompt information, and the third prompt information is used to prompt the user to change the blood pressure measurement plan; the wearable device receives and responds to the user's second operation on the second option in the third prompt information, obtains and saves a first updated blood pressure measurement plan, and the total number of blood pressure measurements in the first updated blood pressure measurement plan is less than the total number of blood pressure measurements in the blood pressure measurement plan; the wearable device obtains the user's blood pressure measurement value in a blood pressure measurement cycle based on the first updated blood pressure measurement plan.

[0346] Optionally, the power required by the first updated blood pressure measurement scheme to complete blood pressure measurement within a blood pressure measurement cycle is less than or equal to the remaining power of the wearable device.

[0347] In this way, when the wearable device is still not in the charging state after the wearable device displays the prompt information, the wearable device can prompt the user again to modify the blood pressure measurement plan and obtain a first updated blood pressure measurement plan.

[0348] In one possible implementation, the method also includes: the wearable device receives and responds to the user's third operation on the third option in the third prompt information, displays a fourth prompt information, and the fourth prompt information is used to prompt the user to set the wearable device to low power consumption mode; the wearable device receives and responds to the user's fourth operation on the fourth option in the fourth prompt information, and enters the low power consumption mode.

[0349] Optionally, the low power consumption mode may refer to shutting down some or all energy-consuming operations on the wearable device 100 that are not related to blood pressure monitoring. For example, energy-consuming operations may include but are not limited to heart rate monitoring functions, motion data recording functions, etc.

[0350] In this way, if the user has not modified the blood pressure measurement plan after the wearable device displays the prompt information, the wearable device can prompt the user again to control the wearable device to enter the low power mode to save the power of the device.

[0351] In a possible implementation, the method further includes: the wearable device receives and responds to the user's fifth operation on the fifth option in the fourth prompt information, and displays a fifth prompt information, where the fifth prompt information is used to prompt the user that the battery of the wearable device is too low.

[0352] In this way, if the wearable device has not entered the low power mode after displaying the prompt message, the wearable device can remind the user that the device battery is too low and may shut down at any time.

[0353] In one possible implementation, the blood pressure measurement value includes a first blood pressure measurement value obtained by the wearable device at a first moment; after the wearable device obtains the first blood pressure measurement value, the method further includes: the wearable device obtaining a current user state; if the current user state meets the blood pressure measurement condition, the wearable device saves the first blood pressure measurement value

[0354] In one possible implementation, the method further includes: when the current user status does not meet the blood pressure measurement conditions, the wearable device obtains a blood pressure compensation value based on the current user status; the wearable device obtains a first blood pressure monitoring value based on the blood pressure compensation value and the first blood pressure measurement value; and the wearable device saves the first blood pressure monitoring value.

[0355] The blood pressure measurement conditions may include but are not limited to one or more of the following: the user is in a stationary state, and the difference between the real-time heart rate and the nighttime resting heart rate is within a preset range.

[0356] Wearable devices can collect motion data using motion sensors. Motion sensors may include, but are not limited to, accelerometers and gyroscopes. Motion sensors can collect motion data or motion trajectories. Wearable devices can determine whether the user is stationary based on the motion data or motion trajectories.

[0357] This allows the wearable device to determine whether the user's condition meets the blood pressure measurement requirements when measuring blood pressure. If so, the blood pressure measurement result can be directly saved. If not, the wearable device needs to correct the blood pressure measurement result and then save the corrected result, which can improve the accuracy of blood pressure measurement.

[0358] In one possible implementation, the method also includes: the wearable device obtains historical blood pressure measurement data, wherein the historical blood pressure measurement data includes historical blood pressure measurement records and historical blood pressure measurement results; the wearable device updates the blood pressure measurement scheme based on the historical blood pressure measurement data, generates and saves a second updated blood pressure measurement scheme; the wearable device obtains the blood pressure measurement value of the user within a blood pressure measurement cycle based on the second updated blood pressure measurement scheme.

[0359] Historical blood pressure measurement records include, but are not limited to, historical blood pressure measurement records and historical blood pressure measurement results. Historical blood pressure measurement records may include, but are not limited to, the start time of the historical blood pressure measurement, the end time of the historical blood pressure measurement, the duration of the historical blood pressure measurement, the number of blood pressure measurements within the duration of the historical blood pressure measurement, the time interval between two adjacent blood pressure measurements within the duration of the historical blood pressure measurement, and the total number of historical blood pressure measurements.

[0360] In this way, the wearable device can periodically / irregularly update the blood pressure measurement solution based on the user's historical data to improve the accuracy of the blood pressure measurement solution generated by the wearable device.
