Description

Technical Field

[0001] The present application claims priority to Chinese Patent Application No. 202311442868.2, filed with the China National Intellectual Property Administration on October 31, 2023, entitled "Method, electronic device and storage medium for generating a blood pressure measurement scheme", which is incorporated herein by reference in its entirety.

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

Background Art

[0003] With the improvement of living standards, people's attention to health has been increasing. Hypertension is a common cardiovascular disease, and regular blood pressure measurement is one of the important means to ensure the health of patients with hypertension. Ambulatory blood pressure measurement is a technology that continuously measures a user's blood pressure for 24 hours without affecting the user's daily activities, and can obtain a plurality of blood pressure measurements within 24 hours. Generally, measurement is performed every 10 to 15 minutes, and the average value of a plurality of blood pressure measurements within 24 hours is used as the blood pressure value. Currently, there are cuff-type sphygmomanometers for measuring a user's ambulatory blood pressure. However, in order to use a cuff-type sphygmomanometer, the user needs to carry the cuff-type sphygmomanometer for 24 hours, which is inconvenient for the user.

[0004] To facilitate a user's blood pressure measurement, a wearable device (e.g., a wristwatch) may be equipped with a blood pressure detection component, so that the user can wear the wearable device to implement ambulatory blood pressure measurement, which saves time and labor. A user may set a blood pressure measurement scheme on the wearable device, for example, may set a blood pressure measurement time and a time interval between two adjacent blood pressure measurements in a blood pressure measurement period. However, the operation of manually setting a blood pressure measurement scheme by a user is cumbersome, and how to simplify the user's operation is a subject for future research. [Overview of the project]

[0005] This application provides a method, electronic device, and storage medium for generating a blood pressure measurement scheme that enables a wearable device to automatically generate a blood pressure measurement scheme for a user, and in which the blood pressure measurement scheme generated by the wearable device is better suited to the user's characteristics and lifestyle, thereby improving the appropriateness of blood pressure measurement.

[0006] According to a first aspect, the application provides a method for generating a blood pressure measurement scheme. The method includes a wearable device acquiring one or more of user information, physiological data, and device status. Based on one or more of the user information, physiological data, and device status, the wearable device generates a blood pressure measurement scheme which includes one or more of the start time of blood pressure measurement, end time of blood pressure measurement, blood pressure measurement period, number of blood pressure measurements during the blood pressure measurement period, time interval between two adjacent blood pressure measurements during the blood pressure measurement period, and total number of blood pressure measurements. Based on the blood pressure measurement scheme, the wearable device acquires the user's blood pressure measurements in one blood pressure measurement cycle.

[0007] For example, one blood pressure measurement cycle may be 24 hours long.

[0008] According to this method, a wearable device can automatically generate a blood pressure measurement scheme based on the fusion of multiple types of information, ensuring that the blood pressure measurement scheme generated by the wearable device is better suited to the user's characteristics. This not only simplifies user operation but also improves the accuracy of blood pressure measurement.

[0009] With respect to the first aspect, in possible implementations, user information includes one or more of gender, age, height, weight, smoking history, alcohol consumption, medical history, medication history, and lifestyle; physiological data includes one or more of heart rate, blood pressure, arteriosclerosis, and blood glucose; and device status includes one or more of battery level and device temperature.

[0010] With respect to the first aspect, in possible implementations, the generation of a blood pressure measurement scheme by a wearable device based on one or more of user information, physiological data, and device status specifically includes the wearable device determining the user's risk level for hypertension based on one or more of user information, physiological data, and device status. The wearable device generates a blood pressure measurement scheme based on the user's risk level for hypertension.

[0011] Different blood pressure measurement schemes are generated for different risk levels of hypertension. For example, the total number of blood pressure measurements determined by a wearable device based on high risk is greater than the total number of blood pressure measurements determined by a wearable device based on low risk.

[0012] In some embodiments, the risk level of hypertension risk may be the risk level at a specific time period within a single blood pressure measurement cycle. For example, the risk level of hypertension risk for a nighttime user is higher than the risk level of hypertension risk for a daytime user. In this case, the total number of nighttime blood pressure measurements is greater than the total number of daytime blood pressure measurements.

[0013] In this way, a wearable device can determine the user's risk level for hypertension based on multiple types of information and generate a blood pressure measurement scheme based on that risk level.

[0014] In a first aspect, in a possible implementation, the method further includes the wearable device displaying first prompt information, which is used to prompt the user to view the details of the blood pressure measurement scheme, after the wearable device has generated a blood pressure measurement scheme. The wearable device accepts and responds to a first operation by the user for a first option in the first prompt information, and displays a first user interface, the details of the blood pressure measurement scheme being displayed in the first user interface.

[0015] In this way, after the wearable device automatically generates a blood pressure measurement scheme, the wearable device can prompt the user to view the details of the blood pressure measurement scheme. In some embodiments, the wearable device may alternatively accept user input to modify the blood pressure measurement scheme.

[0016] With respect to the first aspect, in a possible implementation, before the wearable device obtains the user's blood pressure measurements in a blood pressure measurement cycle through measurements based on a blood pressure measurement scheme, the method further includes the wearable device obtaining the battery level of the wearable device. When the battery level of the wearable device is less than a preset battery level, the wearable device displays second prompt information, which is used to prompt the user to charge the wearable device, and the preset battery level is the minimum battery level required by the wearable device to complete blood pressure measurements in one blood measurement cycle based on a blood pressure measurement scheme. If the wearable device is charging within a first period after the second prompt information is displayed, the wearable device saves the blood pressure measurement scheme.

[0017] In this way, before the wearable device measures blood pressure based on the automatically generated blood pressure measurement scheme, the device needs to determine whether the wearable device has sufficient battery power, thus avoiding the wearable device powering off before completing a blood pressure measurement cycle. When the wearable device displays prompt information and is charging, the wearable device may save the blood pressure measurement scheme and complete a blood pressure measurement cycle based on the blood pressure measurement scheme.

[0018] With respect to the first aspect, in a possible implementation, the method further includes, if the wearable device is not charging within a first period after the display of a second prompt, the wearable device displays a third prompt, the third prompt being used to prompt the user to change the blood pressure measurement scheme. The wearable device accepts a second operation from the user to the second option in the third prompt, responds to the second operation, and obtains and stores a first updated blood pressure measurement scheme, wherein the total number of blood pressure measurements in the first updated blood pressure measurement scheme is less than the total number of blood pressure measurements in the blood pressure measurement scheme. The wearable device obtains the user's blood pressure measurements in one blood measurement cycle based on the first updated blood pressure measurement scheme.

[0019] Optionally, the amount of battery power required to complete blood pressure measurements in one blood measurement cycle based on the first updated blood pressure measurement scheme is less than or equal to the remaining battery power of the wearable device.

[0020] In this way, if the wearable device is still not charging after displaying prompt information, the wearable device can prompt the user again to correct the blood pressure measurement scheme and obtain the first updated blood pressure measurement scheme.

[0021] With respect to the first aspect, in a possible implementation, the method further includes the wearable device receiving a third operation from the user to a third option in third prompt information, responding to the third operation, and displaying fourth prompt information, the fourth prompt information being used to prompt the user to set the wearable device to low power mode. The wearable device receives a fourth operation from the user to a fourth option in the fourth prompt information, responding to the fourth operation, and transitioning to low power mode.

[0022] Optionally, in low-power mode, some or all of the energy-consuming operations for the wearable device 100 that are unrelated to blood pressure monitoring may be disabled. For example, energy-consuming operations may include, but are not limited to, heart rate monitoring functions and motion data recording functions.

[0023] In this way, if the user still does not change the blood pressure measurement scheme after the wearable device displays prompt information, the wearable device can conserve battery power by prompting the user again to control the wearable device to switch to low power mode.

[0024] With respect to the first aspect, in a possible implementation, the method further includes a wearable device receiving a fifth operation from the user for a fifth option in a fourth prompt information, responding to the fifth operation, and displaying a fifth prompt information, the fifth prompt information being used to notify the user that the battery level of the wearable device is too low.

[0025] In this way, if the wearable device still does not enter the low-power mode after displaying the prompt information, the wearable device can notify the user that the battery level of the wearable device is too low and the wearable device may power off at any time.

[0026] With regard to the first aspect, in a possible implementation, the blood pressure measurement value includes a first blood pressure measurement value acquired at a first time point by the wearable device. After the wearable device acquires the first blood pressure measurement value, the method further comprises: the wearable device acquires a current user status. When the current user status satisfies a blood pressure measurement condition, the wearable device stores the first blood pressure measurement value.

[0027] In a possible implementation, the method further comprises: when the current user status does not satisfy the blood pressure measurement condition, the wearable device acquires a blood pressure correction value based on the current user status. The wearable device acquires a first blood pressure monitoring value based on the blood pressure correction value and the first blood pressure measurement value. The wearable device stores the first blood pressure monitoring value.

[0028] The blood pressure measurement condition may include, but is not limited to, one or more of: the user is in a stationary state, and a difference between a real-time heart rate and a nighttime resting heart rate is within a preset range.

[0029] The wearable device may collect motion data based on a motion sensor. The motion sensor may include, but is not limited to, an acceleration sensor, a gyro sensor, and the like. The motion sensor may collect motion data or a motion trajectory. The wearable device may determine whether the user is in a stationary state based on the motion data or the motion trajectory.

[0030] In this way, when the wearable device measures blood pressure, the wearable device can determine whether the user status meets the blood pressure measurement conditions. When the blood pressure measurement conditions are satisfied, the wearable device may directly store the blood pressure measurement result. When the blood pressure measurement conditions are not satisfied, in order to improve the accuracy of blood pressure measurement, the wearable device needs to correct the blood pressure measurement result, and then store the corrected blood pressure measurement result.

[0031] With respect to the first aspect, in a possible implementation, the method further comprises: the wearable device acquires historical blood pressure measurement data, wherein the historical blood pressure measurement data comprises 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, and generates and stores a second updated blood pressure measurement scheme. The wearable device acquires the user's blood pressure measurement values in one blood measurement cycle based on the second updated blood pressure measurement scheme.

[0032] The historical blood pressure measurement data includes, but is not limited to, historical blood pressure measurement records and historical blood pressure measurement results. The historical blood pressure measurement records may include, but are not limited to, the start time point of historical blood measurement, the end time point of historical blood measurement, the duration of historical blood measurement, the number of blood pressure measurements during the historical blood measurement period, the time interval between two adjacent blood pressure measurements during the historical blood measurement period, and the total number of historical blood measurements, etc.

[0033] In this way, the wearable device can periodically or aperiodically update the blood pressure measurement scheme based on the user's historical data, so as to improve the accuracy of the blood pressure measurement scheme generated by the wearable device.

[0034] According to a second aspect, the present application provides a wearable device. The wearable device includes memory and a processor. The memory is coupled to the processor. The memory is configured to store a computer program. When the processor invokes the computer program, the wearable device becomes capable of performing a method for generating a blood pressure measurement scheme in any possible implementation of any one of the aforementioned aspects.

[0035] According to a third aspect, the present application provides a computer-readable storage medium containing instructions. When the instructions are executed on a wearable device, the wearable device becomes capable of performing a method for generating a blood pressure measurement scheme in any possible implementation of any one of the aforementioned aspects.

[0036] According to a fourth aspect, the present application provides a chip system, the chip system comprising one or more processors, the processors configured to invoke computer instructions to perform a method for generating a blood pressure measurement scheme in any possible implementation of any one of the aforementioned aspects.

[0037] According to a fifth aspect, the present application provides a computer program product including instructions. When the computer program product is executed on a wearable device, the wearable device becomes capable of performing a method for generating a blood pressure measurement scheme in any possible implementation of any one of the aforementioned aspects.

[0056] [Figure 15] This is a schematic method flowchart of the method for generating a blood pressure measurement scheme according to this application. [Modes for carrying out the invention]

[0057] The technical solutions in the embodiments of this application will be described in detail and clearly below with reference to the attached drawings. In the description of the embodiments of this application, " / " means "or" unless otherwise specified. For example, A / B may mean A or B. In this application, "and / or" describes only the relationship between related objects and indicates that three relationships may exist. For example, A and / or B may indicate the following three cases: that only A exists, that both A and B exist, and that only B exists. In addition, in the description of the embodiments of this application, "multiple" means two or more.

[0058] The terms “First” and “Second” used herein are for illustrative purposes only and should not be understood as an indication or suggestion of relative importance or an implicit indication of the number of technical features shown. Thus, features limited by “First” or “Second” may include one or more features, explicitly or implicitly. In the description of embodiments of this application, “multiple” means two or more unless otherwise specified.

[0059] In the following embodiments of this application, the term "user interface (UI)" refers to a mediating interface for interaction and information exchange between an application or operating system and a user. A user interface implements the conversion between an internal format of information and a format that the user can accept. A user interface is typically represented in the form of a graphical user interface (GUI) and is a graphically displayed user interface related to the operation of a computer. A user interface may be a visual interface element displayed on the display of an electronic device, such as text, icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, or widgets.

[0060] With the advancement of electronic technology, the functionality of wearable devices is continuously being enhanced. For example, wearable devices such as bands and watches can provide blood pressure measurement functions, helping users 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.

[0061] The wearable device 100 provided in this application, which can be used to measure blood pressure, is described below.

[0062] Figure 1 shows a user wearing the wearable device 100.

[0063] As shown in Figure 1, the user may wear the wearable device 100 on their wrist.

[0064] Figure 2 shows the structural configuration of the wearable device 100.

[0065] As shown in Figure 2, the wearable device 100 may include a watch body 201 and a wearable component 202.

[0066] The watch body 201 is equipped with motion sensors, such as a gyroscope and an accelerometer. The motion sensors are configured to collect motion data and determine whether the user is asleep based on the motion status obtained through analysis of the motion data.

[0067] The watch body 201 may include a display 203. The display 203 may be configured to display the time, the battery level of the watch body 201, a Bluetooth identifier, received messages, user motion data, and other content. The display 203 may be configured to accept user taps to turn the display on or enable or disable sports mode. The display 203 may further record the user's steps taken and calories burned, and may have basic functions such as incoming call reminders and message notifications. In possible implementations, the watch body 201 may establish a wireless communication connection to a wearable device 100 via Bluetooth. The watch body 201 may transmit user motion data to the wearable device 100 with which the connection has been established. Additionally, when the wearable device 100 receives an incoming call or message notification, the watch body 201 may accept commands from the mobile phone and notify the user of the incoming call or message notification.

[0068] The wearable component 202 is used to attach the watch body 201. For example, the wearable component 202 may be a wristband strap, a watch strap, or another device. The wearable component 202 is a device that allows the watch body 201 to be worn on the user's wrist. The wearable device 100 is worn on the user's wrist, and an inertial sensor collects motion data of the user's wrist to monitor the movement of the user's wrist and determine the user's posture.

[0069] When the wearable device 100 starts measuring blood pressure, the wearable device 100 may control the wearable component 202 to contract and then expand in order to measure the user's blood pressure.

[0070] In some embodiments, the process of measuring blood pressure by a wearable device 100 may include the wearable device 100 first inflating a wearable component 202 to temporarily occlude an upper limb artery, then recording the pressure value of the wearable component 202 and the pulse signal generated by the pulse during a slow contraction, and finally determining the user's blood pressure based on the pressure value of the wearable component 202 and the amplitude or envelope of the pulse signal. Blood flow causes lateral pressure on the vessel walls. Changes in the magnitude of lateral pressure cause slight vibrations in the vessel walls. A pulse signal is a signal generated by these minute vibrations of the vessel walls. Determining the user's blood pressure based on the pressure value of the wearable component 202 and the amplitude or envelope of the pulse signal is also called the oscillometric method.

[0071] In another embodiment, the process of measuring blood pressure by the wearable device 100 may include the wearable device 100 gradually inflating a wearable component 202 so that the upper limb artery changes from a gradually occluded state to a completely occluded state, recording the pressure value of the wearable component 202 and the pulse signal generated by the pulse, and then determining the user's blood pressure based on the pressure value of the wearable component 202 and the amplitude or envelope of the pulse signal, and finally performing a systole. Blood flow causes lateral pressure on the vessel walls. Changes in the magnitude of lateral pressure cause slight vibrations of the vessel walls. A pulse signal is a signal generated by these minute vibrations of the vessel walls. Determining the user's blood pressure based on the pressure value of the wearable component 202 and the amplitude or envelope of the pulse signal is also called the oscillometric method.

[0072] Figure 3A is an illustrative diagram of the principle of the oscillometric method according to one embodiment of this application.

[0073] As shown in Figure 3A, in the process in which the wearable device 100 inflates the wearable component 202 to temporarily occlude the upper limb artery, the wearable component 202 is in a state where the pressure gradually increases until it reaches a stable level, and the artery gradually goes from an occluded state to a completely occluded state. Then, during a slow contraction, the wearable component 202 is in a state where the pressure gradually decreases to 0, and the artery goes from a completely occluded state to an unoccluded state. The pressure value and pulse signal of the wearable component 202 are recorded when the pressure of the wearable component 202 is gradually decreasing to 0. When the pressure value of the wearable component 202 is greater than or equal to the systolic pressure, the artery is occluded, and the pulse signal is a fine vibration wave. When the pressure value of the wearable component 202 gradually decreases and is less than the systolic pressure but greater than the mean pressure, the artery is gradually no longer occluded, and the amplitude of the pulse signal continuously increases. When the pressure value of the wearable component 202 becomes equal to the mean pressure, the amplitude of the pulse signal reaches its maximum value. As the pressure value of the wearable component 202 gradually decreases, and is greater than the diastolic pressure but less than the mean pressure, the amplitude of the pulse signal gradually decreases. When the pressure value of the wearable component 202 is less than the diastolic pressure, the pulse signal is a minute vibration wave. Therefore, the wearable device 100 can determine the user's systolic and diastolic pressure based on the changes in the pressure value of the wearable component 202 and the amplitude of the pulse signal. In possible implementations, the pressure value of the wearable component 202 and the pulse signal may be determined by a built-in pressure sensor within the wearable device 100.

[0074] Figure 3B is another illustrative diagram of the principle of the oscillometric method according to one embodiment of this application.

[0075] As shown in Figure 3B, in the process in which the wearable device 100 inflates the wearable component 202 to temporarily occlude the upper limb artery, the wearable component 202 is in a state where the pressure gradually increases until it reaches a stable level, and the artery gradually moves from an occluded state to a completely occluded state. The pressure value and pulse signal of the wearable component 202 are recorded when the pressure of the wearable component 202 is gradually increasing until it reaches a stable level. When the pressure value of the wearable component 202 is gradually increasing and the diastolic pressure is less than the mean pressure, the pulse signal is a fine vibration wave. When the pressure value of the wearable component 202 continues to gradually increase and is greater than the diastolic pressure and less than the mean pressure, the amplitude of the pulse signal gradually increases. When the pressure value of the wearable component 202 becomes equal to the mean pressure, the amplitude of the pulse signal reaches its maximum value. When the pressure value of the wearable component 202 is gradually increasing and is greater than the mean pressure and less than the systolic pressure, the artery is gradually occluded, and the amplitude of the pulse signal continuously decreases. When the pressure value of the wearable component 202 is greater than or equal to the systolic pressure, the artery is occluded, and the pulse signal is a minute vibration wave. Therefore, the wearable device 100 can determine the user's systolic and diastolic pressure based on the pressure value of the wearable component 202 and the change in the amplitude of the pulse signal. In possible implementations, the pressure value of the wearable component 202 and the pulse signal may be determined by a built-in pressure sensor within the wearable device 100.

[0076] Figure 4A is a diagram of the hardware structure of wearable device 100.

[0077] As shown in Figure 4A, the wearable device may be a band, a wristwatch, or other wearable device, or the wearable device 100 may be a non-wearable device such as a wall-mounted blood pressure monitor. In this embodiment, the specific type of wearable device is not particularly limited. In this embodiment, only the example in which the wearable device 100 is a wristwatch is used for illustrative purposes.

[0078] The 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, internal memory 207, a SIM card interface 208, a USB interface 209, a power management module 210, a battery 211, and a charge management module 212. The sensor module 203 may include a touch sensor 203A, a 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 passage communication component 203H. The function of the airbag 203D is the same as that of the wearable component 202.

[0079] The structures shown in this embodiment of the present invention can be understood as not constituting any particular limitation on wearable devices. In some other embodiments of this application, wearable devices may include more or fewer components than those shown in the figures, some components may be combined, some components may be separated, or the components may be arranged differently. The components shown in the figures may be implemented using hardware, software, or a combination of software and hardware.

[0080] Processor 200A may include one or more processing units. For example, processor 200A may include an application processor (AP), a modem processor, a graphics processing unit (GPU), an image signal processor (ISP), a controller, a video codec, a digital signal processor (DSP), a baseband processor, and / or a neural network processing unit (NPU). Different processing units may be independent components or may be integrated into one or more processors.

[0081] In some embodiments, the processor 200A may include one or more interfaces. These interfaces may include an inter-integrated circuit (I2C) interface, an inter-integrated circuit sound (I2S) interface, a pulse code modulation (PCM) interface, a universal asynchronous receiver / transmitter (UART) interface, a mobile industry processor interface (MIPI), a general-purpose input / output (GPIO) interface, a subscriber identity module (SIM) interface, a universal serial bus (USB) interface, and the like.

[0082] In some embodiments, the processor 200A may be an alternative microcontroller unit (MCU).

[0083] The I2C interface is a bidirectional synchronous serial bus that includes a serial data line (SDA) and a serial clock line (SCL). In some embodiments, the processor 200A may include multiple groups of I2C buses. The processor 200A may be separately coupled to a touch sensor 203A, a power management module 210, etc., via different I2C bus interfaces. For example, the processor 200A may be coupled to the touch sensor 203A via an I2C interface, so that the processor 200A communicates with the touch sensor 203A via the I2C bus interface to implement touch functionality for a wearable device.

[0084] The I2S interface may be used for audio communication. The PCM interface may also be used for audio communication, as well as for sampling, quantization, and encoding of analog signals.

When charging the battery 211, the charge management module 212 may also supply power to the wearable device via the power management module 210.

[0089] The power management module 210 is configured to connect to the battery 211, the charge management module 212, and the processor 200A.

For example, touch operations performed for different applications (e.g., taking photos and playing audio) may correspond to different vibration feedback effects. Motor 206 may also correspond to different vibration feedback effects for touch operations performed on different areas of the display 205.

[0096] The internal memory 207 may include one or more random access memory (RAM) and one or more non-volatile memory (NVM).

[0097] Random access memory may include static random access memory (SRAM), dynamic random access memory (DRAM), synchronous dynamic random access memory (SDRAM), double data rate synchronous dynamic random access memory (DDR SDRAM, for example, fifth-generation DDR SDRAM is commonly called DDR5 SDRAM), and others.

The SIM card interface 208 is also compatible with external memory cards. The wearable device interacts with the network via the SIM card to implement functions such as calling and data communication. In some embodiments, an eSIM, or embedded SIM card, is used in the wearable device. The eSIM card may be embedded in a wearable device and cannot be separated from the wearable device.

[0100] In some embodiments, the wearable device 100 may, alternatively, not include the SIM card interface 208.

[0101] The touch sensor 203A is also referred to as a “touch device.” The touch sensor 203A may be disposed on the display 205. The touch sensor 203A and the display 205 constitute a touchscreen, also called a touch screen. The touch sensor 203A is configured to detect touch operations performed on or near the touch sensor. The touch sensor may transmit the detected touch operations to an application processor to determine the type of touch event. The display 205 may provide a visual output related to the touch operation. In some other embodiments, the touch sensor 203A may, alternatively, be disposed on the surface of the wearable device at a location different from that of the display 205.

[0102] The pressure sensor 203B is configured to measure pressure. In some embodiments of this application, a wearable device measures the pressure inside the airbag 203D by the pressure sensor 203B. In some embodiments of this application, some components of the pressure sensor 203B are located inside the airbag 203D and are configured to sense the pressure inside the airbag 203D.

[0103] The air pump 203C is configured to perform inflation and deflation. In some embodiments of this application, the wearable device inflates the airbag 203D by the air pump 203C, and the air pump 203C is connected to the airbag 203D via an air passage communication component 203H. The airbag 203D is configured to compress the user's blood vessels.

[0104] The magnetic sensor 203E includes a Hall effect sensor. In some embodiments of this application, the wearable device may determine by the magnetic sensor 203F whether the airbag 203D on the wearable device has been removed. For example, the airbag 203D, or a watch strap connected to the airbag 203D, may be provided with a magnet. The wearable device may also determine by the magnetic sensor whether the airbag 203D on the wearable device has been removed by determining the magnetic flux generated by the airbag 203D or a magnet on the airbag 203D.

[0105] The PPG sensor 203F is configured to acquire user health data based on the PPG signals collected by the PPG sensor 203F. User health data includes, but is not limited to, heart rate, blood oxygen, respiratory rate, and blood oxygen saturation (SaO2).

[0106] The motion sensor 203G includes, but is not limited to, an acceleration sensor and an angular velocity sensor. The motion sensor 203G may be configured to collect motion data, determine the user's motion status based on the motion data, and then determine whether the user is asleep based on the user's motion status.

[0107] The air passage communication component 203H may be an independent component, or it may be an air passage formed by combining it with other hardware modules, or it may be part of another component, for example, part of the air pump 203C, or part of the air bag 203D.

[0108] The sensor module 203 may further include an accelerometer, an infrared sensor, and the like.

[0109] As shown in Figure 4B, when the wearable device 100 is a wristwatch, the airbag 203D is attached to the side of the wearable component 202 that is closer to the body. The air pump 203C is connected to the airbag 203D via the air passage communication component 203H. The airbag 203D may be attached to only one side of the wearable component 202, and that side of the wearable component 202 may be located above the arterial location of the user's wrist, for example, above the radial artery location.

[0110] The air pump 203C may be located in the watch body of the smartwatch. The airbag 203D may be connected to the buckle of the watch strap, and the airbag 203D is connected to the watch face via an air vent cover. Correspondingly, the airbag 203D may be separated from the watch strap or separated from the watch face.

[0111] Currently, the user may configure a blood pressure measurement scheme on the wearable device 100.

[0112] A blood pressure measurement scheme may include one or more blood pressure measurement policies. A blood pressure measurement policy may include, but is not limited to, the start time of blood pressure measurement, the end time of blood pressure measurement, the blood pressure measurement period, the number of blood pressure measurements during the blood pressure measurement period, the time interval between two adjacent blood pressure measurements during the blood pressure measurement period, and the total number of blood pressure measurements.

[0113] The start time for blood pressure measurement may be any time during the day when the user begins measuring their blood pressure. For example, the start time for blood pressure measurement may be 9:00 AM or 10:00 PM.

[0114] The end point of blood pressure measurement may be any point in the day when the user's blood pressure measurement is stopped. For example, the end point of blood pressure measurement may be 12:00 PM or 6:00 AM.

[0115] The blood pressure measurement period may be a time period between two points in the day, during which the user's blood pressure is measured. The blood pressure measurement period for a day may include one or more time periods. For example, the blood pressure measurement period may be from 9:00 AM to 12:00 PM and / or from 10:00 PM to 6:00 AM the following day.

[0116] The frequency of blood pressure measurements during a blood pressure measurement period may be the total number of blood pressure measurements taken during that period. For example, if the blood pressure measurement period is from 9:00 AM to 12:00 PM, the frequency of blood pressure measurements may be 6 times, or if the blood pressure measurement period is from 10:00 PM to 6:00 AM the following day, the frequency of blood pressure measurements may be 30 times.

[0117] The time interval between two adjacent blood pressure measurements within a blood pressure measurement period may be the time difference between two adjacent blood pressure measurement points within a single blood pressure measurement period. The time difference between two adjacent blood pressure measurement points within a single blood pressure measurement period may remain the same or may change. For example, if the blood pressure measurement period is from 9:00 AM to 12:00 PM, the time difference between two adjacent blood pressure measurement points may be 30 minutes.

[0118] The total number of blood pressure measurements may be the total number of measurements taken during a 24-hour period from 0:00 to midnight. For example, the total number of blood pressure measurements in a day may be 36.

[0119] In addition to the blood pressure measurement policy described above, the blood pressure measurement scheme may further include other blood pressure measurement policies. This is not limited to the present application.

[0120] Figures 5A to 5D illustrate how the user manually configures the blood pressure measurement scheme.

[0121] For example, the wearable device 100 may display the user interface 510 shown in Figure 5A. Options 501 and 502 are displayed on the user interface 510. The user may manually configure the blood pressure measurement scheme by using options 501 and 502.

[0122] For example, as shown in Figure 5A, the wearable device 100 may accept user input (e.g., a tap) on option 501 on the user interface 510, and in response to the user input, the wearable device 100 may display the user interface 520 shown in Figure 5B. Several blood pressure measurement policies for the blood pressure measurement scheme are displayed on the user interface 520. For example, the user may manually set the time interval between two adjacent daytime blood pressure measurements and the time interval between two adjacent nighttime blood pressure measurements. For example, the time interval between two adjacent daytime blood pressure measurements set by the user may be 30 minutes, and the time interval between two adjacent nighttime blood pressure measurements set by the user may also be 30 minutes.

[0123] In addition to the time intervals for blood pressure measurement, the wearable device 100 may also accept user input to set up a different blood pressure measurement policy. This is not limited to the present application.

[0124] Next, the wearable device 100 may accept a user input (e.g., a tap) for the blood pressure measurement start option on the user interface 520. In response to the user input, the wearable device 100 may save the blood pressure measurement scheme set by the user and start measuring the user's blood pressure when the conditions of the blood pressure measurement scheme are met.

[0125] As another example, as shown in Figure 5C, the wearable device 100 may accept user input (e.g., a tap) on option 502 on the user interface 510, and in response to the user input, the wearable device 100 may display the user interface 530 shown in Figure 5D. Several blood pressure measurement policies of the blood pressure measurement scheme are displayed on the user interface 530. The blood pressure measurement scheme may be pre-configured. For example, a pre-configured blood pressure measurement scheme includes time intervals between two adjacent blood pressure measurements during the day and 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.

[0126] Next, the wearable device 100 may accept a user input (e.g., a tap) for the blood pressure measurement start option on the user interface 530. In response to the user input, the wearable device 100 may save a pre-configured blood pressure measurement scheme and start measuring the user's blood pressure when the conditions of the pre-configured blood pressure measurement scheme are met.

[0127] Figures 5A to 5D are merely diagrams illustrating the manual creation of a blood pressure measurement scheme; users may, alternatively, manually create blood pressure measurement schemes in other implementation forms. This is not limited to the present application.

[0128] Figures 5A to 5D show that the blood pressure measurement scheme must be manually created or manually configured by the user. The complexity of the user operation, and the fact that the blood pressure measurement scheme must be manually created or manually configured by the user, does not necessarily meet user requirements and leads to a poor user experience.

[0129] From this perspective, this application provides a method for generating a blood pressure measurement scheme. The wearable device 100 may automatically generate a blood pressure measurement scheme based on one or more pieces of information, such as user information, physiological data, and device status. This simplifies user operation by eliminating the need for the user to manually create a blood pressure measurement scheme.

[0130] A blood pressure measurement scheme may include one or more blood pressure measurement policies. A blood pressure measurement policy may include, but is not limited to, the start time of blood pressure measurement, the end time of blood pressure measurement, the blood pressure measurement period, the number of blood pressure measurements during the blood pressure measurement period, the time interval between two adjacent blood pressure measurements during the blood pressure measurement period, and the total number of blood pressure measurements.

[0131] The blood pressure measurement scheme cycle may be 24 hours or a different cycle. This is not limited to the present application.

[0132] User information includes, but is not limited to, one or more of the following: gender, age, height, weight, smoking status, drinking status, medical history, medication status, and lifestyle.

[0133] Physiological data include, but are not limited to, one or more of the following: heart rate, blood pressure, arteriosclerosis, blood glucose, etc.

[0134] Device status includes, but is not limited to, one or more of the following: battery level, device temperature, etc.

[0135] The wearable device 100 may determine the user's hypertension risk based on user information, physiological data, device status, etc., and acquire a blood pressure measurement scheme based on the user's hypertension risk. Different blood pressure measurement schemes may be acquired for different hypertension risks.

[0136] Optionally, the blood pressure measurement scheme may be a 24-hour blood pressure measurement scheme.

[0137] Optionally, different users may have different user information, physiological data, and device status, and the wearable device 100 may obtain different blood pressure measurement schemes.

[0138] For example, when a user's risk of hypertension is determined to be high, the measurement mode of the blood pressure measurement scheme acquired by the wearable device 100 may be a high-frequency measurement mode, or when a user's risk of hypertension is determined to be low, the measurement mode of the blood pressure measurement scheme acquired by the wearable device 100 may be a low-frequency measurement mode.

[0139] The total number of blood pressure measurements in high-frequency measurement mode is greater than the total number of blood pressure measurements in low-frequency measurement mode.

[0140] Optionally, the total number of blood pressure measurements may be the total number of blood pressure measurements taken in a single day (24 hours).

[0141] In another embodiment, the high-frequency measurement mode and the low-frequency measurement mode may alternatively be measurement modes for specific time periods.

[0142] For example, the wearable device 100 may, when it determines that the user's risk of hypertension is high only during the first time period, measure the user's blood pressure in high-frequency measurement mode only during the first time period, and measure the user's blood pressure in low-frequency measurement mode at all other times.

[0143] For example, if the wearable device 100 determines that the user's risk of hypertension is high only between 8:00 AM and 12:00 PM, and that the user's risk of hypertension is low between 12:00 AM and 8:00 AM, and between 12:00 PM and midnight, it may measure the user's blood pressure in high-frequency measurement mode between 8:00 AM and 12:00 PM, and measure the user's blood pressure in low-frequency measurement mode between 12:00 AM and 8:00 AM, and between 12:00 PM and midnight.

[0144] In some embodiments, the wearable device 100 may further subdivide high-risk individuals into different high-risk levels and enable different measurement modes based on these different high-risk levels.

[0145] For example, high risk may be further divided into a first-level risk and a second-level risk, with the first-level risk being higher than the second-level risk. In addition to these two levels, high risk may be optionally divided into many other levels. This is not limited to the present application.

[0146] The wearable device 100 may measure the user's blood pressure in a first high-frequency measurement mode during the first period and in a second high-frequency measurement mode during the second period if it determines that the user's risk of hypertension is at level 1 during the first time period and at level 2 during the second time period. 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.

[0147] For example, if the wearable device 100 determines that the user's risk of hypertension is at level 1 from 8:00 a.m. to 10:00 a.m., at level 2 from 10:00 a.m. to 12:00 p.m., and that the user's risk of hypertension is low from 12:00 a.m. to 8:00 a.m. and from 12:00 p.m. to midnight, it may measure the user's blood pressure in a first high-frequency measurement mode from 8:00 a.m. to 10:00 a.m., measure the user's blood pressure in a second high-frequency measurement mode from 10:00 a.m. to 12:00 p.m., and measure the user's blood pressure in a low-frequency measurement mode from 12:00 a.m. to 8:00 a.m. and from 12:00 p.m. to midnight.

[0148] In some embodiments, the wearable device 100 may determine the start time for blood pressure measurement based on the user's lifestyle.

[0149] The wearable device 100 can determine the user's lifestyle based on collected user data, such as the user's past travel data and past passenger records, and then determine the start time for blood pressure measurement based on the user's lifestyle, thereby avoiding interference with the user's daily activities.

[0150] For example, the wearable device 100 may determine, based on collected user data, that the user is on their way to work between 7:00 AM and 8:30 AM. In this case, the start time of blood pressure measurement in the blood pressure measurement scheme determined by the wearable device 100 may extend beyond the 7:00 AM to 8:30 AM timeframe.

[0151] Optionally, after the wearable device 100 determines the blood pressure measurement scheme, the wearable device 100 may prompt the user to view the details of the blood pressure measurement scheme and decide whether to save and use the blood pressure measurement scheme.

[0152] Figures 6A and 6B illustrate a blood pressure measurement scheme proposed to the user by the wearable device 100.

[0153] After the wearable device 100 determines the blood pressure measurement scheme, the wearable device 100 may prompt the user to view the details of the blood pressure measurement scheme and then prompt the user to decide whether to save and use the blood pressure measurement scheme.

[0154] As shown in Figure 6A, the wearable device 100 can display a prompt bar 601, which contains the prompt information, "Do you want to save and use the blood pressure measurement scheme?". The prompt bar 601 is used to prompt the user to view the details of the blood pressure measurement scheme.

[0155] The prompt bar 601 includes options 602, 603, and 604. The wearable device 100 may accept user input (e.g., a tap) for option 602, and in response to the user input, the wearable device 100 may display the details of blood pressure measurement scheme 1. Alternatively, the wearable device 100 may accept user input (e.g., a tap) for option 603, and in response to the user input, the wearable device 100 may display the details of blood pressure measurement scheme 2. Alternatively, the electronic wearable device 100 may accept user input (e.g., a tap) for option 604, and in response to the user input, the wearable device 100 may display the details of blood pressure measurement scheme 3.

[0156] For example, as shown in Figure 6A, the wearable device 100 may accept user input (e.g., a tap) on option 604 in prompt bar 601, and in response to the user input, the wearable device 100 may display prompt bar 605 as shown in Figure 6B, where the details of blood pressure measurement scheme 3 are displayed. For example, the details of blood pressure measurement scheme 3 may include that the time interval between two adjacent blood pressure measurements during the day is 30 minutes, and that the time interval between two adjacent blood pressure measurements at night is also 30 minutes. The user may view the details of blood pressure measurement scheme 3 on prompt bar 605. Prompt bar 605 further includes an OK option and a Modify option. The user may save blood pressure measurement scheme 3 by using the OK option. Alternatively, the user may modify blood pressure measurement scheme 3 by using the Modify option and then save the modified blood pressure measurement scheme 3.

[0157] The wearable device 100 prompts the user to change the blood pressure measurement scheme based on the remaining battery level.

[0158] In some embodiments, after the wearable device 100 determines and saves a blood pressure measurement scheme, and before the wearable device 100 uses the blood pressure measurement scheme, the wearable device 100 determines the minimum battery amount required by the blood pressure measurement scheme, compares this minimum battery amount with the remaining battery level of the wearable device 100, and determines whether it is necessary to change the saved blood pressure measurement scheme, thereby avoiding a situation where the wearable device 100 powers off and cannot measure blood pressure due to insufficient battery power.

[0159] Figures 7A and 7B are schematic flowcharts of a method for prompting the user to change the blood pressure measurement scheme by the wearable device 100 based on the remaining battery level.

[0160] S701: The wearable device 100 acquires one or more of the following: user information, physiological data, and device status.

[0161] User information includes, but is not limited to, one or more of the following: gender, age, height, weight, smoking status, drinking status, medical history, and medication status.

[0162] Physiological data include, but are not limited to, one or more of the following: heart rate, blood pressure, arteriosclerosis, blood glucose, etc.

[0163] Device status includes, but is not limited to, one or more of the following: battery level, device temperature, etc.

[0164] The wearable device 100 may determine the user's hypertension risk based on user information, physiological data, device status, etc., and acquire a blood pressure measurement scheme based on the user's hypertension risk. Different blood pressure measurement schemes may be acquired for different hypertension risks.

[0165] S702: The wearable device 100 determines the blood pressure measurement scheme based on one or more user information from user information, physiological data, and device status.

[0166] A blood pressure measurement scheme may include one or more blood pressure measurement policies. A blood pressure measurement policy may include, but is not limited to, the start time of blood pressure measurement, the end time of blood pressure measurement, the blood pressure measurement period, the number of blood pressure measurements during the blood pressure measurement period, the time interval between two adjacent blood pressure measurements during the blood pressure measurement period, and the total number of blood pressure measurements.

[0167] Optionally, the blood pressure measurement scheme may be a 24-hour blood pressure measurement scheme.

[0168] Optionally, different users may have different user information, physiological data, and device status, and the wearable device 100 may obtain different blood pressure measurement schemes.

[0169] For example, when a user's risk of hypertension is determined to be high, the measurement mode of the blood pressure measurement scheme acquired by the wearable device 100 may be a high-frequency measurement mode, or when a user's risk of hypertension is determined to be low, the measurement mode of the blood pressure measurement scheme acquired by the wearable device 100 may be a low-frequency measurement mode.

[0170] The total number of blood pressure measurements in high-frequency measurement mode is greater than the total number of blood pressure measurements in low-frequency measurement mode.

[0171] In another embodiment, the blood pressure measurement scheme may alternatively be determined by another device (e.g., a mobile phone or server) that has established a communication connection to the wearable device 100 and transmitted to the wearable device 100.

[0172] S703: The wearable device 100 determines the minimum battery level based on the blood pressure measurement scheme.

[0173] The minimum battery capacity may also be the minimum battery capacity required to complete the total number of blood pressure measurements in a blood pressure measurement scheme over a day.

[0174] After the wearable device 100 acquires a blood pressure measurement scheme, the wearable device 100 may estimate, based on the blood pressure measurement scheme, the minimum battery capacity required to complete the total number of blood pressure measurements in a day in order to meet the requirements of the blood pressure measurement scheme for initiating high-frequency blood pressure measurements.

[0175] Optionally, the wearable device 100 may estimate the minimum battery amount required to complete a total number of blood pressure measurements in a day, based on the average battery amount required to complete one blood pressure measurement in the blood pressure measurement scheme and the total number of blood pressure measurements.

[0176] S704: The wearable device 100 determines whether the minimum battery level is greater than the remaining battery level of the wearable device 100.

[0177] The wearable device 100 may obtain the battery level of the wearable device 100 and determine whether the minimum battery level is greater than the battery level of the wearable device 100.

[0178] S705 is executed when it is determined that the minimum battery level is greater than the remaining battery level of wearable device 100.

[0179] S706 is executed when it is determined that the minimum battery level is lower than the remaining battery level of wearable device 100.

[0180] S705: Wearable device 100 stores blood pressure measurement scheme.

[0181] When it is determined that the minimum battery level is greater than the remaining battery level of the wearable device 100, the remaining battery level of the wearable device 100 can provide the minimum battery level required to complete the total number of blood pressure measurements in the blood pressure measurement scheme for one day, and the wearable device 100 saves the blood pressure measurement scheme.

[0182] In some embodiments, before the wearable device 100 saves the blood pressure measurement scheme, the wearable device 100 may display the user interface shown in Figures 6A and 6B to prompt the user to view the blood pressure measurement scheme. Alternatively, the user may actively modify the blood pressure measurement scheme and save the modified blood pressure measurement scheme.

[0183] S706: The wearable device 100 prompts the user to perform charging and determines whether charging is being performed.

[0184] When it is determined that the minimum battery level is less than the remaining battery level of the wearable device 100, the remaining battery level of the wearable device 100 is insufficient to provide the minimum battery level required to complete the total number of blood pressure measurements in the blood pressure measurement scheme in a day, and the wearable device 100 may prompt the user to charge the wearable device 100.

[0185] S705 is executed when it is determined that charging is in progress.

[0186] S707 is executed when it is determined that charging is not taking place.

[0187] For example, when it is determined that the minimum battery level is lower than the remaining battery level of the wearable device 100, the wearable device 100 may display prompt information 801 as shown in Figure 8A. Prompt information 801 includes the text information, "Battery level is too low. Do you want to charge the device?" Prompt information 801 is used to prompt the user to charge the wearable device 100 as soon as possible. Prompt information 801 further includes OK and Cancel options. The user may decide to charge the wearable device 100 by using the OK option. Alternatively, the user may decide not to charge the wearable device 100 by using the Cancel option.

[0188] S707: The wearable device 100 prompts the user to change the blood pressure measurement scheme and determines whether the user has agreed to the change in the blood pressure measurement scheme.

[0189] When the wearable device 100 determines that charging is not taking place, it prompts the user to change the blood pressure measurement scheme and determines whether the user has agreed to change the blood pressure measurement scheme.

[0190] Adjusting the blood pressure measurement scheme may involve reducing the total number of blood pressure measurements in the scheme, thereby reducing the power consumption of the wearable device 100, and ensuring that the battery level of the wearable device 100 supports the completion of blood pressure measurements throughout the day.

[0191] In possible implementations, the wearable device 100 may automatically reduce the total number of blood pressure measurements in the blood pressure measurement scheme based on the remaining battery level of the wearable device 100, so that the remaining battery level of the wearable device 100 can support the completion of the total number of blood pressure measurements in the modified blood pressure measurement scheme.

[0192] In another possible implementation, the wearable device 100 may accept an operation from the user to reduce the total number of blood pressure measurements in the blood pressure measurement scheme, and the battery level of the wearable device 100 may be such that it can support the completion of the total number of blood pressure measurements in the modified blood pressure measurement scheme.

[0193] In some embodiments, after the wearable device 100 displays prompt information 801, the wearable device 100 may determine whether the wearable device 100 is charged. If the wearable device 100 detects that the wearable device 100 is not charged within a first period (e.g., 1 minute), it may display prompt information 802 as shown in Figure 8B. Prompt information 802 includes the text information, "Current battery level is too low. Do you accept adjustment of the blood pressure measurement scheme?" Prompt information 802 is used to prompt the user to accept adjustment of the blood pressure measurement scheme in order to reduce the number of blood pressure measurements. Prompt information 802 further includes Yes and No options. The user may decide to accept adjustment of the blood pressure measurement scheme by using the Yes option. Alternatively, the user may decline to accept adjustment of the blood pressure measurement scheme by using the No option.

[0194] S708 is executed when the user agrees to a change in the blood pressure measurement scheme.

[0195] S709 is executed when the user does not consent to a change in the blood pressure measurement scheme.

[0196] S708: Wearable device 100 stores a modified blood pressure measurement scheme.

[0197] When the user consents to a change in the blood pressure measurement scheme, the wearable device 100 may save the modified blood pressure measurement scheme.

[0198] S709: The wearable device 100 prompts the user to switch to low power mode and determines whether the user has agreed to switch to low power mode.

[0199] If the user does not consent to a change in the blood pressure measurement scheme, the wearable device 100 may prompt the user to switch to a low-power mode to reduce the power consumption of the wearable device 100 and conserve battery power. The wearable device 100 needs to determine whether the user consents to switching to a low-power mode.

[0200] Controlling the wearable device 100 to switch to a low-power mode may involve disabling some or all of the energy-consuming operations of the wearable device 100 that are unrelated to blood pressure monitoring. For example, energy-consuming operations may include, but are not limited to, heart rate monitoring functions and motion data recording functions.

[0201] S705 is executed when the user agrees to put the wearable device 100 into low-power mode.

[0202] S710 is executed when the user does not agree to put the wearable device 100 into low power mode.

[0203] For example, as shown in Figure 8B, the wearable device 100 accepts a user input operation (e.g., a tap) for the No option in prompt information 802, and in response to the user input operation, the wearable device 100 does not adjust the blood pressure measurement scheme.

[0204] After the user chooses not to adjust the blood pressure measurement scheme, the wearable device 100 may display prompt information 803 as shown in Figure 8C. Prompt information 803 includes the text information: "Current battery level is too low. Do you want to switch to low power mode?" Prompt information 803 is used to prompt the user to control the wearable device 100 to switch to low power mode in order to reduce the power consumption of the wearable device 100 and conserve battery power. Prompt information 803 further includes Yes and No options. The user may control the wearable device 100 to switch to low power mode by using the Yes option. Alternatively, the user may control the wearable device 100 not to switch to low power mode by using the No option.

[0205] S710: Wearable device 100 notifies the user that the battery level is too low and that wearable device 100 may power off at any time.

[0206] If the user does not agree to put the wearable device 100 into low power mode, the wearable device 100 may notify the user that the battery level is too low and the wearable device 100 may power off at any time.

[0207] For example, as shown in Figure 8C, the wearable device 100 may accept a user input operation (e.g., a tap) in response to the No option in the prompt information 803, and in response to the user input operation, the wearable device 100 does not switch to low power mode.

[0208] In response to a user input for the "No" option in prompt information 803, the wearable device 100 may display prompt information 804 as shown in Figure 8D. Prompt information 804 may include the text information: "Battery level is too low. The device may power off at any time. Please charge the device as soon as possible." The text information is intended to inform the user that the battery level of the wearable device 100 is too low.

[0209] Optionally, in the embodiments shown in Figures 7A and 7B, before starting blood pressure measurement for the day, it is determined whether the battery level of the wearable device 100 is too low, and an appropriate policy is selected to reduce the power consumption of the wearable device 100 and improve the usage period of the wearable device 100's battery.

[0210] The wearable device 100 uses a blood pressure measurement scheme and displays the result of a single blood pressure measurement.

[0211] The wearable device 100 may, after acquiring a blood pressure measurement scheme, monitor the user's blood pressure over the course of a day based on that scheme.

[0212] From the above explanation, it is clear that a blood pressure measurement scheme may include one or more blood pressure measurement policies. A blood pressure measurement policy may include, but is not limited to, the start time of blood pressure measurement, the end time of blood pressure measurement, the blood pressure measurement period, the number of blood pressure measurements during the blood pressure measurement period, the time interval between two adjacent blood pressure measurements during the blood pressure measurement period, and the total number of blood pressure measurements.

[0213] In some embodiments, before measuring blood pressure using a blood pressure measurement scheme, the wearable device 100 needs to determine whether the current user status meets the blood pressure measurement conditions. When the blood pressure measurement conditions are met, the wearable device 100 starts measuring the user's blood pressure. When the blood pressure measurement conditions are not met, the wearable device 100 does not measure the user's blood pressure. The wearable device 100 starts measuring the user's blood pressure only when the blood pressure measurement conditions are met.

[0214] Figure 9 is a schematic flowchart of the method for measuring a user's blood pressure using a wearable device 100.

[0215] S901: Wearable device 100 retrieves the current user status.

[0216] The current user status may include, but is not limited to, one or more of the following: motion data, physiological data, etc.

[0217] Motion data may include acceleration data, angular velocity data, cumulative steps, etc.

[0218] Physiological data may include real-time heart rate, nocturnal resting heart rate, etc. Nocturnal resting heart rate may be the average value of heart rates measured by the wearable device 100 during the night.

[0219] S902: The wearable device 100 determines whether the current user status meets the blood pressure measurement conditions.

[0220] Blood pressure measurement conditions may include, but are not limited to, one or more of the following: the user is at rest, and the difference between real-time heart rate and nighttime resting heart rate is within a preset range.

[0221] The wearable device 100 may collect motion data based on motion sensors. The motion sensors may include, but are not limited to, accelerometers, gyroscopes, etc. The motion sensors may collect motion data or motion trajectories. The wearable device 100 may determine whether the user is stationary based on the motion data or motion trajectories.

[0222] Typically, when a user is at rest, they are mostly inactive and their real-time heart rate is stable. If the difference between the real-time heart rate and the nighttime resting heart rate is within a preset range, it can be determined that the user is at rest. The wearable device 100 may also determine whether the user is at rest based on the real-time heart rate collected by the PPG sensor.

[0223] S903 is executed when the current user status is determined to meet the blood pressure measurement conditions.

[0224] S901 is executed when it is determined that the current user status does not meet the blood pressure measurement conditions.

[0225] In this way, the wearable device 100 can determine whether the blood pressure measurement conditions are met before measuring blood pressure. When the blood pressure measurement conditions are met, the wearable device 100 can start measuring the user's blood pressure and improve the accuracy of the blood pressure measurement. The reason for this is that when the blood pressure measurement conditions are not met, the user may be in a non-static state, such as running or exercising. In this case, the blood pressure result of the wearable device 100 will have an error.

[0226] S903: The wearable device 100 determines whether the time difference between the previous blood pressure measurement and the current time meets a preset time interval.

[0227] When the wearable device 100 determines that the current user status meets the blood pressure measurement conditions, it may determine, before starting blood pressure measurement, whether the time difference between the previous blood pressure measurement and the current time meets a preset time interval.

[0228] S904 is executed when it is determined that the time difference between the previous blood pressure measurement and the current time satisfies a predetermined time interval.

[0229] S901 is executed when it is determined that the time difference between the previous blood pressure measurement and the current time does not meet the pre-set time interval.

[0230] From the above explanation, it can be seen that the blood pressure measurement scheme determined by the wearable device 100 may include one or more blood pressure measurement policies. The blood pressure measurement policy may include, but is not limited to, the start time of blood pressure measurement, the end time of blood pressure measurement, the blood pressure measurement period, the number of blood pressure measurements during the blood pressure measurement period, the time interval between two adjacent blood pressure measurements during the blood pressure measurement period, and the total number of blood pressure measurements.

[0231] Before starting blood pressure measurement, the wearable device 100 needs to determine whether the time difference between the previous blood pressure measurement and the current time is within a preset time interval specified in the blood pressure measurement scheme.

[0232] The pre-set time intervals vary depending on the blood pressure measurement period. For example, the pre-set time interval may be 20 minutes from 9:00 AM to 12:00 PM, and 30 minutes from 9:00 PM to 9:00 AM.

[0233] The wearable device 100 may determine, before starting blood pressure measurement, whether the time difference between the previous blood pressure measurement and the current time satisfies a preset time interval. When the preset time interval is met, the wearable device 100 starts measuring the user's blood pressure to avoid frequent blood pressure measurements.

[0234] S904: Wearable device 100 measures the user's blood pressure and stores the blood pressure measurement results.

[0235] The wearable device 100 may start measuring the user's blood pressure and save the blood pressure measurement results when it determines that the time difference between the previous blood pressure measurement and the current time satisfies a preset time interval.

[0236] In some embodiments, in order to ensure the accuracy of blood pressure measurement, the wearable device 100 may display prompt information to encourage the user to measure their blood pressure.

[0237] Figures 10A to 10E show how the wearable device 100 displays prompt information to encourage the user to measure their blood pressure.

[0238] For example, as shown in Figure 10A, when the wearable device 100 starts measuring blood pressure, the wearable device 100 may display the user interface 710 shown in Figure 10A to ensure the accuracy of the blood pressure measurement results. The following prompt information, namely, "It's time to measure your blood pressure. Stay still and tap to start the measurement," is displayed on the user interface 710. The prompt information is used to remind the user to remain still during the blood pressure measurement to avoid inaccuracies in the blood pressure measurement results due to exercise. The user interface 710 further includes a measurement reminder option and a skip option. The user may view the precautions for blood pressure measurement by using the measurement reminder option. Alternatively, the user may start measuring blood pressure directly without viewing the precautions by using the skip option.

[0239] For example, as shown in Figure 10A, the wearable device 100 may accept user input (e.g., a tap) on the user interface 710 for measurement reminder options, and in response to user input, the wearable device 100 may display the user interface 720 shown in Figure 10B. The user interface 720 includes prompt information such as, "During measurement, keep the watch at heart level and do not press it against your heart." This prompt information is used to inform the user of the correct measurement posture. The user interface 720 also includes a timer option 7201. The timer option 7201 is used to prompt the user to raise the watch to heart level within a preset time.

[0240] After the countdown time displayed on the wearable device 100 reaches zero, the wearable device 100 may begin measuring the user's blood pressure.

[0241] Optionally, during the process in which the wearable device 100 measures the user's blood pressure, the wearable device 100 may display the user interface 730 shown in Figure 10C. The user interface 730 includes a prompt message, "Please remain still during blood pressure measurement," to encourage the user to remain still during blood pressure measurement, thereby avoiding inaccuracies in blood pressure measurement results due to exercise. The user interface 730 further includes a measurement cancellation option. The user may stop blood pressure measurement by using the measurement cancellation option.

[0242] In some embodiments, after the wearable device 100 acquires blood pressure monitoring values, the wearable device 100 may display the user interface 740 shown in Figure 10D. The user interface 740 includes blood pressure measurements. The blood pressure measurements may include systolic pressure and diastolic pressure. For example, the systolic pressure may be 130 mmHg and the diastolic pressure may be 80 mmHg. In some embodiments, the user interface 740 may further include pulses. For example, the pulses may be 69 times per minute.

[0243] In some embodiments, after the wearable device 100 acquires blood pressure monitoring values, the wearable device 100 may alternatively display the user interface 750 shown in Figure 10E. 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, and the time interval until the next blood pressure measurement, is displayed on the user interface 750. For example, as shown in Figure 10E, the user status is static, the total number of blood pressure measurements is 5, the interval since the last blood pressure measurement acquisition is 20 minutes, and the estimated time until the start of the next blood pressure measurement is also 20 minutes.

[0244] The user interface 750 further includes an OK option and a blood pressure measurement scheme optimization option. The user may use the OK option to allow the wearable device 100 to stop displaying the user interface 750. Alternatively, the user may actively modify the blood pressure measurement scheme by using the blood pressure measurement scheme optimization option. See the description of the embodiments below for further details. Further details are not described herein.

[0245] In some embodiments, the wearable device 100 can, alternatively, avoid frequently disturbing the user by directly starting blood pressure measurement without displaying the prompt information shown in Figures 10A to 10E. For example, at night, the wearable device 100 does not need to display the prompt information shown in Figures 10A to 10E, and can automatically measure the user's blood pressure without displaying the prompt information, thus avoiding disturbing the user's rest.

[0246] In some embodiments, the wearable device 100 may 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. When the blood pressure measurement conditions are met, the wearable device 100 may save the blood pressure measurement result directly. When the blood pressure measurement conditions are not met, the wearable device 100 may determine a blood pressure correction value based on the current user status, correct the blood pressure measurement result based on the blood pressure correction value, and save the corrected blood pressure measurement result.

[0247] Figure 11 is a schematic flowchart of another method for measuring a user's blood pressure using a wearable device 100.

[0248] S1101: The wearable device 100 determines whether the time difference between the previous blood pressure measurement and the current time satisfies a preset time interval.

[0249] Before starting blood pressure measurement, the wearable device 100 needs to determine whether the time difference between the previous blood pressure measurement and the current time meets a predetermined time interval.

[0250] S1102 is executed when it is determined that the time difference between the previous blood pressure measurement and the current time satisfies a predetermined time interval.

[0251] If the time difference between the previous blood pressure measurement and the current time is determined to be less than the predetermined time interval, the process terminates, and blood pressure is not measured again until the time difference between the previous blood pressure measurement and the current time reaches the predetermined time interval.

[0252] From the above explanation, it can be seen that the blood pressure measurement scheme determined by the wearable device 100 may include one or more blood pressure measurement policies. The blood pressure measurement policy may include, but is not limited to, the start time of blood pressure measurement, the end time of blood pressure measurement, the blood pressure measurement period, the number of blood pressure measurements during the blood pressure measurement period, the time interval between two adjacent blood pressure measurements during the blood pressure measurement period, and the total number of blood pressure measurements.

[0253] Before starting blood pressure measurement, the wearable device 100 needs to determine whether the time difference between the previous blood pressure measurement and the current time is within a preset time interval specified in the blood pressure measurement scheme.

[0254] The pre-set time intervals vary depending on the blood pressure measurement period. For example, the pre-set time interval may be 20 minutes from 9:00 AM to 12:00 PM, and 30 minutes from 9:00 PM to 9:00 AM.

[0255] The wearable device 100 may determine, before starting blood pressure measurement, whether the time difference between the previous blood pressure measurement and the current time satisfies a preset time interval. When the preset time interval is met, the wearable device 100 starts measuring the user's blood pressure to avoid frequent blood pressure measurements.

[0256] S1102: Wearable device 100 measures blood pressure and obtains the blood pressure measurement result.

[0257] The wearable device 100 may start measuring blood pressure and save the blood pressure measurement results when it determines that the time difference between the previous blood pressure measurement and the current time satisfies a preset time interval.

[0258] S1103: Wearable device 100 retrieves the current user status.

[0259] S1104: The wearable device 100 determines whether the current user status meets the blood pressure measurement conditions.

[0260] The wearable device 100 obtains the current user status and determines whether the current user status meets the blood pressure measurement conditions.

[0261] For explanations of S1103 and S1104, please refer to the explanations of S901 and S902. Further details will not be explained again in this application.

[0262] S1105 is executed when it is determined that the current user status meets the blood pressure measurement conditions.

[0263] S1106 is executed when it is determined that the current user status does not meet the blood pressure measurement conditions.

[0264] S1105: Wearable device 100 stores blood pressure measurement results.

[0265] When the wearable device 100 determines that the current user status meets the blood pressure measurement conditions, it may directly save the blood pressure measurement results.

[0266] S1106: The wearable device 100 obtains a blood pressure correction value based on the current user status.

[0267] The wearable device 100 may obtain a blood pressure correction value based on the current user status when it determines that the current user status does not meet the blood pressure measurement conditions. The determined blood pressure correction value will vary depending on the different user statuses.

[0268] S1107: The wearable device 100 obtains a corrected blood pressure measurement based on the blood pressure correction value and the blood pressure measurement.

[0269] S1108. Wearable device 100 stores corrected blood pressure measurements.

[0270] The wearable device 100 may, after determining whether the current user status meets the blood pressure measurement conditions, obtain a blood pressure correction value based on the current user status, correct the blood pressure measurement based on the blood pressure correction value, and obtain a corrected blood pressure measurement. This is intended to eliminate the influence of a user status that does not meet the blood pressure measurement conditions on the blood pressure measurement.

[0271] After obtaining corrected blood pressure measurements, the wearable device 100 may store the corrected blood pressure measurements.

[0272] From the embodiments of FIGS. 7A and 7B, it can be seen that after the wearable device 100 determines the blood pressure measurement scheme and before the wearable device 100 uses the blood pressure measurement scheme, the wearable device 100 may determine the minimum amount of battery required by the blood pressure measurement scheme. When the remaining battery power of the wearable device 100 is too low, the user can charge the wearable device 100 as soon as possible, which avoids the situation where the wearable device 100 powers off due to insufficient battery power and cannot measure blood pressure.

[0273] In some embodiments, before measuring blood pressure, the wearable device 100 needs to detect whether the wearable device 100 is in a worn state. When the wearable device 100 is in an unworn state, the user is prompted to put on the wearable device 100 in a timely manner and start blood pressure measurement.

[0274] FIG. 12 is a schematic flowchart of still another method for measuring a user's blood pressure by the wearable device 100.

[0275] S1201: The wearable device 100 recognizes that the wearable device 100 is in an unworn state.

[0276] S1202: The wearable device 100 determines whether the remaining battery power of the wearable device 100 satisfies the minimum battery amount required by the blood pressure measurement scheme.

[0277] The wearable device 100 may determine whether the wearable device 100 is worn on the user's wrist. When the wearable device 100 is not worn on the user's wrist, the wearable device 100 determines that the wearable device 100 is in an unworn state.

[0278] The wearable device 100 may obtain the remaining battery level of the wearable device 100 and determine the minimum amount of battery required to complete the blood pressure measurement scheme based on the blood pressure measurement scheme.

[0279] The wearable device 100 needs to determine whether its battery level is greater than the minimum battery level required by the blood pressure measurement scheme.

[0280] S1203 is executed when the battery level of wearable device 100 is lower than the minimum battery level required by the blood pressure measurement scheme.

[0281] S1204 is executed when the battery level of wearable device 100 is greater than the minimum battery level required by the blood pressure measurement scheme.

[0282] S1203: The wearable device 100 sends message 1 to the electronic device 200, which indicates to the electronic device 200 that message 1 is urging the user to charge the wearable device 100 as soon as possible.

[0283] When the battery level of the wearable device 100 is lower than the minimum battery level required by the blood pressure measurement scheme, in order to avoid the wearable device 100 being unable to measure blood pressure due to insufficient battery power, the wearable device 100 may send message 1 to the electronic device 200 with which it has established a communication connection, and message 1 indicates to the electronic device 200 that it is urging the user to charge the wearable device 100 as soon as possible.

[0284] After the electronic device 200 receives message 1 sent by the wearable device 100, the electronic device 200 may prompt the user to charge the wearable device 100 as soon as possible.

[0285] Optionally, the prompting method may include, but is not limited to, vibration, sound, pop-up windows, flashing lights, etc.

[0286] Optionally, the electronic device 200 may use different prompting methods depending on the different usage status.

[0287] For example, when the electronic device 200 is in use, the electronic device 200 may prompt the user to charge the wearable device 100 as soon as possible by using a pop-up window.

[0288] For example, as shown in Figure 13A, the electronic device 200 may display a prompt bar 1301 in a floating manner on the home screen, which contains prompt information such as "Battery level is too low. Please charge the wearable device 100 as soon as possible." The prompt bar 1301 is used to prompt the user to charge the wearable device 100 as soon as possible.

[0289] For example, as shown in Figure 13B, the electronic device 200 may display prompt information 1302 in a dropdown notification bar. Prompt information 1302 includes the message, "Battery level is too low. Please charge the wearable device 100 as soon as possible." Prompt information 1302 is used to prompt the user to charge the wearable device 100 as soon as possible.

[0290] In addition to the method shown in Figures 13A and 13B in which the electronic device 200 displays prompt information to encourage the user to charge the wearable device 100 as soon as possible, the electronic device 200 may, alternatively, prompt the user to charge the wearable device 100 as soon as possible in another manner. Details are not described herein in this embodiment of the application.

[0291] In another example, when the electronic device 200 is in an unused state, the electronic device 200 may remind the user to charge the wearable device 100 as soon as possible through one or more methods selected from among vibration, sound, and flashing light.

[0292] S1204: the wearable device 100 determines whether a current user status satisfies a blood pressure measurement condition.

[0293] When the remaining power of the battery of the wearable device 100 is higher than the minimum battery capacity required by the blood pressure measurement scheme, the wearable device 100 needs to determine whether the current user status satisfies the blood pressure measurement condition. When the current user status satisfies the blood pressure measurement condition, the wearable device 100 starts measuring the user's blood pressure.

[0294] For the description of S1204, reference can be made to the descriptions of S901 and S902. The details are not repeated here in the present application.

[0295] When it is determined that the current user status satisfies the blood pressure measurement condition, S1205 is executed.

[0296] When it is determined that the current user status does not satisfy the blood pressure measurement condition, the user status is continuously monitored until the user status satisfies the blood pressure measurement condition.

[0297] S1205: the wearable device 100 determines whether the blood pressure measurement time is after a first preset time.

[0298] The wearable device 100 may, when it determines that the current user status meets the conditions for blood pressure measurement, determine whether the blood pressure measurement time is after a first preset time before measuring blood pressure. In this way, the electronic device 200 can prompt the user in advance and in a timely manner to put on the wearable device 100 to measure blood pressure.

[0299] When it is determined that the blood pressure measurement time is after a first preset time, S1206 is executed, and the electronic device 200 can prompt the user in advance and in a timely manner to put on the wearable device 100 to measure blood pressure.

[0300] S1204 is executed when it is determined that the blood pressure measurement time is not after the first preset time.

[0301] S1206: The wearable device 100 sends message 2 to the electronic device 200, which indicates to the electronic device 200 that message 2 is urging the user to put on the wearable device 100 as soon as possible.

[0302] When the wearable device 100 determines that the blood pressure measurement time is not after a first preset time, the wearable device 100 may send message 2 to the electronic device 200, with which it has established a communication connection, so that the electronic device 200 can prompt the user to put on the wearable device 100 in advance and in a timely manner. Message 2 indicates to the electronic device 200 that it is urging the user to put on the wearable device 100 as soon as possible.

[0303] The electronic device 200 may prompt the user to put on the wearable device 100 as soon as possible after receiving message 2 transmitted by the wearable device 100.

[0304] Optionally, the prompting method may include, but is not limited to, vibration, sound, pop-up windows, flashing lights, etc.

[0305] Optionally, the electronic device 200 may use different prompting methods depending on the different usage status.

[0306] For example, when the electronic device 200 is in use, the electronic device 200 may prompt the user to put on the wearable device 100 as soon as possible by using a pop-up window.

[0307] For example, as shown in Figure 13C, the electronic device 200 may display a prompt bar 1303 in a floating manner on the home screen, and the prompt bar 1303 contains prompt information such as, "We will measure your blood pressure. Please put on the wearable device 100 as soon as possible." The prompt bar 1301 is used to prompt the user to put on the wearable device 100 as soon as possible.

[0308] For example, as shown in Figure 13D, the electronic device 200 may display prompt information 1304 in a dropdown notification bar. Prompt information 1304 includes the message, "We will measure your blood pressure. Please put on the wearable device 100 as soon as possible." Prompt information 1304 is used to prompt the user to put on the wearable device 100 as soon as possible.

[0309] In addition to the method shown in Figures 13C and 13D in which the electronic device 200 displays prompt information to encourage the user to put on the wearable device 100 as soon as possible, the electronic device 200 may, alternatively, prompt the user to put on the wearable device 100 as soon as possible in another manner. Details are not described herein in this embodiment of the application.

[0310] In another example, when the electronic device 200 is not in use, it may prompt the user to put on the wearable device 100 as soon as possible using one or more methods such as vibration, sound, and flashing light.

[0311] The wearable device 100 displays the blood pressure measurement results for a cycle after completing blood pressure measurements in that cycle using a blood pressure measurement scheme.

[0312] For example, a 24-hour cycle could be considered one cycle.

[0313] Figures 14A to 14D show the blood pressure measurement results in one cycle, as measured by a wearable device 100 or an electronic device 200.

[0314] For example, after the wearable device 100 has completed blood pressure measurement in one cycle, the wearable device 100 may display the user interface 1410 shown in Figure 14A. The user interface 1410 includes the blood pressure measurement results for one cycle. For example, the mean systolic pressure over 24 hours is 125 mmHg, the mean diastolic pressure over 24 hours is 70 mmHg, the mean systolic pressure during the day is 130 mmHg, the mean diastolic pressure during the day is 75 mmHg, the mean systolic pressure at night is 110 mmHg, and the mean diastolic pressure at night is 65 mmHg. The following prompt information, namely, "For a detailed report, please refer to your mobile phone," is further displayed on the user interface 1410. The user may view detailed information about the blood pressure measurement results for one cycle on the electronic device 200.

[0315] For example, Figure 14B shows a user interface 1420 on an electronic device 200, displaying details of blood pressure measurements in one cycle. As shown in Figure 14B, the user interface 1420 includes sleep onset time, wake-up time, and a dynamic blood pressure trend chart for one cycle. Sleep onset time may be 8:30 p.m. on October 11, 2023. Wake-up time may be 8:30 a.m. on October 12, 2023. The dynamic blood pressure trend chart shows the trend of blood pressure changes in one cycle. The user interface 1420 further includes the following information: namely, the number of blood pressure measurements is 50. In one cycle (e.g., 24 hours), the mean systolic pressure is 125 mmHg and the mean diastolic pressure is 70 mmHg. In one cycle (e.g., 24 hours), the mean daytime systolic pressure is 130 mmHg and the mean daytime diastolic pressure is 75 mmHg. In one cycle (e.g., 24 hours), the mean systolic pressure at night is 110 mmHg, and the mean diastolic pressure at night is 65 mmHg. The diurnal variation in one cycle (e.g., 24 hours) is dipper-type. Based on the blood pressure measurement results in one cycle, interpretations and suggestions, namely that the blood pressure level is within the normal range, the diurnal variation is normal, and it is recommended to continue monitoring blood pressure, are further displayed in the user interface 1400.

[0316] In another embodiment, if the wearable device 100 has not completed blood pressure measurements in one cycle, for example, if it has only completed multiple blood pressure measurements in one time period, the user may view the blood pressure detection results for that time period on the wearable device 100 or the electronic device 200.

[0317] For example, as shown in Figure 14C, the wearable device 100 displays the user interface 1430, which displays the average pressure measurements for that time period. For example, during that time period, the average systolic pressure is 125 mmHg and the average diastolic pressure is 70 mmHg. The following prompt information, namely, "For a detailed report, please refer to your mobile phone," is further displayed on the user interface 1430. The user may also view detailed information about the blood pressure measurement results for that time period on the electronic device 200.

[0318] For example, Figure 14D shows the user interface 1440 on the electronic device 200, displaying details of blood pressure measurements over a single time period. As shown in Figure 14D, the user interface 1440 includes the start time of blood pressure measurement, the end time of blood pressure measurement, and a dynamic blood pressure trend chart for that time period. The start time of blood pressure measurement may be 6:30 a.m. on October 11, 2023. The end time of blood pressure measurement may be 9:30 a.m. on October 11, 2023. The dynamic blood pressure trend chart shows the trend of blood pressure changes over a single time period. The user interface 1440 further includes the following information: namely, the number of blood pressure measurements is 10. During that time period, the mean systolic pressure is 125 mmHg and the mean diastolic pressure is 70 mmHg. Based on the blood pressure measurement results for that time period, interpretations and suggestions are displayed, namely, during the measurement period, the mean pressure values ​​are at the normal level of 125 / 70 mmHg, and if an overall evaluation is needed, it is further indicated that 24-hour measurements should be completed.

[0319] The wearable device 100 corrects the blood pressure measurement scheme based on historical blood pressure measurement data to obtain an optimized blood pressure measurement scheme.

[0320] In some embodiments, the wearable device 100 may acquire historical blood pressure measurement data within a first period (e.g., one month) and correct the blood pressure measurement scheme acquired by the wearable device 100 based on the historical blood pressure measurement data within the first period.

[0321] 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 historical blood measurement, the end time of historical blood measurement, the period of historical blood measurement, the number of blood pressure measurements during the period of historical blood measurement, the time interval between two adjacent blood pressure measurements during the period of historical blood measurement, and the total number of historical blood measurements.

[0322] In possible implementations, the wearable device 100 may periodically or irregularly correct the blood pressure measurement scheme based on historical blood pressure measurement data to obtain an optimized blood pressure measurement scheme. In this way, the optimized blood pressure measurement scheme better suits the user's behavioral characteristics.

[0323] In another possible implementation, the wearable device 100 may alternatively accept user input and correct the blood pressure measurement scheme based on historical blood pressure measurement data to obtain an optimized blood pressure measurement scheme. In this way, the optimized blood pressure measurement scheme better suits the user's behavioral characteristics.

[0324] For example, if the wearable device 100 determines, based on historical blood pressure measurement data, that the user has hypertension, the total number of blood pressure measurements in the optimized blood pressure measurement scheme determined by the wearable device 100 may be increased to monitor the user's blood pressure in more detail.

[0325] In another example, when the wearable device 100 determines, based on historical blood pressure measurement data, that the user is a normal-pressure user, the wearable device 100 may reduce the total number of blood pressure measurements in the optimized blood pressure measurement scheme determined by the wearable device 100, thereby reducing the power consumption of the wearable device 100.

[0326] In another example, when the wearable device 100 determines, based on historical blood pressure measurement data, that the user's blood pressure is high between 9:00 AM and 11:00 AM, the total number of blood pressure measurements taken between 9:00 AM and 11:00 AM in the optimized blood pressure measurement scheme determined by the wearable device 100 is increased. The user's blood pressure may be monitored in more detail between 9:00 AM and 11:00 AM.

[0327] Figure 15 is a schematic method flowchart of the method for generating a blood pressure measurement scheme according to this application.

[0328] S1501: A wearable device acquires one or more of the following: user information, physiological data, and device status.

[0329] S1502: A wearable device generates a blood pressure measurement scheme based on one or more of user information, physiological data, and device status, the blood pressure measurement scheme including one or more of the start time of blood pressure measurement, end time of blood pressure measurement, blood pressure measurement period, number of blood pressure measurements during the blood pressure measurement period, time interval between two adjacent blood pressure measurements during the blood pressure measurement period, and total number of blood pressure measurements.

[0330] S1503: The wearable device obtains the user's blood pressure measurements in one blood pressure measurement cycle based on a blood pressure measurement scheme.

[0331] For example, one blood pressure measurement cycle may be 24 hours long.

[0332] According to this method, a wearable device can automatically generate a blood pressure measurement scheme based on the fusion of multiple types of information, ensuring that the blood pressure measurement scheme generated by the wearable device is better suited to the user's characteristics. This not only simplifies user operation but also improves the accuracy of blood pressure measurement.

[0333] In possible implementations, user information includes one or more of the following: gender, age, height, weight, smoking history, alcohol consumption, medical history, medication history, and lifestyle; physiological data includes one or more of the following: heart rate, blood pressure, arteriosclerosis, and blood glucose; and device status includes one or more of the following: battery level and device temperature.

[0334] In possible implementations, a wearable device generating a blood pressure measurement scheme based on one or more of user information, physiological data, and device status specifically includes the wearable device determining the user's risk level for hypertension based on one or more of user information, physiological data, and device status. The wearable device generates a blood pressure measurement scheme based on the user's risk level for hypertension.

[0335] Different blood pressure measurement schemes are generated for different risk levels of hypertension. For example, the total number of blood pressure measurements determined by a wearable device based on high risk is greater than the total number of blood pressure measurements determined by a wearable device based on low risk.

[0336] In some embodiments, the risk level of hypertension risk may be the risk level at a specific time period within a single blood pressure measurement cycle. For example, the risk level of hypertension risk for a nighttime user is higher than the risk level of hypertension risk for a daytime user. In this case, the total number of nighttime blood pressure measurements is greater than the total number of daytime blood pressure measurements.

[0337] In this way, a wearable device can determine the user's risk level for hypertension based on multiple types of information and generate a blood pressure measurement scheme based on that risk level.

[0338] In a possible implementation, after the wearable device has generated a blood pressure measurement scheme, the method further includes the wearable device displaying first prompt information, which is used to prompt the user to view the details of the blood pressure measurement scheme. The wearable device accepts and responds to a first operation by the user for a first option in the first prompt information, displays a first user interface, and the details of the blood pressure measurement scheme are displayed in the first user interface.

[0339] In this way, after the wearable device automatically generates a blood pressure measurement scheme, the wearable device can prompt the user to view the details of the blood pressure measurement scheme. In some embodiments, the wearable device may alternatively accept user input to modify the blood pressure measurement scheme.

[0340] In possible implementations, before the wearable device obtains the user's blood pressure measurements in a blood pressure measurement cycle through measurements based on a blood pressure measurement scheme, the method further includes the wearable device obtaining the battery level of the wearable device. When the battery level of the wearable device is less than a preset battery level, the wearable device displays a second prompt, which is used to prompt the user to charge the wearable device, and the preset battery level is the minimum battery level required by the wearable device to complete blood pressure measurements in one blood measurement cycle based on a blood pressure measurement scheme. If the wearable device is charging within a first period after the second prompt is displayed, the wearable device saves the blood pressure measurement scheme.

[0341] In this way, before the wearable device measures blood pressure based on the automatically generated blood pressure measurement scheme, the device needs to determine whether the wearable device has sufficient battery power, thus avoiding the wearable device powering off before completing a blood pressure measurement cycle. When the wearable device displays prompt information and is charging, the wearable device may save the blood pressure measurement scheme and complete a blood pressure measurement cycle based on the blood pressure measurement scheme.

[0342] In a possible implementation, the method further includes the fact that if the wearable device is not charging within a first period after the display of a second prompt, the wearable device displays a third prompt, which is used to prompt the user to change the blood pressure measurement scheme. The wearable device accepts the user's second action to the second option in the third prompt, responds to the second action, obtains and stores a first updated blood pressure measurement scheme, the total number of blood pressure measurements in the first updated blood pressure measurement scheme is less than the total number of blood pressure measurements in the blood pressure measurement scheme. The wearable device obtains the user's blood pressure measurements in one blood measurement cycle based on the first updated blood pressure measurement scheme.

[0343] Optionally, the amount of battery power required to complete blood pressure measurements in one blood measurement cycle based on the first updated blood pressure measurement scheme is less than or equal to the remaining battery power of the wearable device.

[0344] In this way, if the wearable device is still not charging after displaying prompt information, the wearable device can prompt the user again to correct the blood pressure measurement scheme and obtain the first updated blood pressure measurement scheme.

[0345] In possible implementations, the method further includes the wearable device receiving a third user action on a third option in a third prompt information, responding to the third action, and displaying a fourth prompt information, the fourth prompt information being used to prompt the user to set the wearable device to low power mode. The wearable device receives a fourth user action on a fourth option in the fourth prompt information, responding to the fourth action, and transitioning to low power mode.

[0346] Optionally, in low-power mode, some or all of the energy-consuming operations for the wearable device 100 that are unrelated to blood pressure monitoring may be disabled. For example, energy-consuming operations may include, but are not limited to, heart rate monitoring functions and motion data recording functions.

[0347] In this way, if the user still does not change the blood pressure measurement scheme after the wearable device displays prompt information, the wearable device can conserve battery power by prompting the user again to control the wearable device to switch to low power mode.

[0348] In possible implementations, the method further includes the wearable device receiving a fifth operation from the user for a fifth option in a fourth prompt information, responding to the fifth operation, and displaying a fifth prompt information, the fifth prompt information being used to notify the user that the battery level of the wearable device is too low.

[0349] In this way, if a wearable device displays a prompt but still does not enter low-power mode, the wearable device can notify the user that the wearable device's battery level is too low and that the wearable device may power off at any time.

[0350] In a possible implementation, the blood pressure measurement includes a first blood pressure measurement taken by a wearable device at a first point in time. After the wearable device has taken the first blood pressure measurement, the method further includes the wearable device taking the current user status. When the current user status satisfies the blood pressure measurement conditions, the wearable device saves the first blood pressure measurement.

[0351] In possible implementations, the method further includes the wearable device obtaining a blood pressure correction value based on the current user status when the current user status does not meet the blood pressure measurement conditions. The wearable device obtains a first blood pressure monitoring value based on the blood pressure correction value and the first blood pressure measurement. The wearable device stores the first blood pressure monitoring value.

[0352] Blood pressure measurement conditions may include, but are not limited to, one or more of the following: the user is at rest, and the difference between real-time heart rate and nighttime resting heart rate is within a preset range.

[0353] A wearable device may collect motion data based on motion sensors. Motion sensors may include, but are not limited to, accelerometers, gyroscopes, etc. Motion sensors may collect motion data or motion trajectories. Based on the motion data or motion trajectories, the wearable device may determine whether the user is stationary.

[0354] In this way, when measuring blood pressure, the wearable device can determine whether the user status meets the blood pressure measurement conditions. When the blood pressure measurement conditions are met, the wearable device may directly save the blood pressure measurement results. When the blood pressure measurement conditions are not met, the wearable device needs to correct the blood pressure measurement results to improve the accuracy of the blood pressure measurement, and then save the corrected blood pressure measurement results.

[0355] In possible implementations, the method further includes a wearable device acquiring historical blood pressure measurement data, the historical blood pressure measurement data including 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 stores a second updated blood pressure measurement scheme. The wearable device acquires the user's blood pressure measurements in one blood measurement cycle based on the second updated blood pressure measurement scheme.

[0356] The historical blood pressure measurement record includes, but is not limited to, the historical blood pressure measurement record and the historical blood pressure measurement results. The historical blood pressure measurement record may also include, but is not limited to, the start time of the historical blood measurement, the end time of the historical blood measurement, the period of the historical blood measurement, the number of blood pressure measurements during the period of the historical blood measurement, the time interval between two adjacent blood pressure measurements during the period of the historical blood measurement, and the total number of historical blood measurements.

[0357] In this way, the wearable device can periodically or irregularly update the blood pressure measurement scheme based on the user's historical data, thereby improving the accuracy of the blood pressure measurement scheme generated by the wearable device.
