Description

Technical Field

[0001] The present application relates to the field of wearable technology, and in particular to a method for generating a blood pressure measurement solution, an electronic device, and a storage medium. Background Art

[0002] With the improvement of living standards, people's physical health has received more and more attention. As a common cardiovascular disease, hypertension and regular blood pressure measurement are one of the important means to ensure the health of hypertensive patients. Dynamic blood pressure measurement is a technology that measures the user's blood pressure for 24 consecutive hours without affecting the user's daily activities, and can obtain multiple blood pressure measurements within 24 hours. Generally, the blood pressure is measured every 10-15 minutes, and the average of multiple blood pressure measurements within 24 hours is taken as the blood pressure value. At present, there are cuff-type blood pressure monitors to measure the user's dynamic blood pressure, but the cuff-type blood pressure monitor requires the user to carry the cuff-type blood pressure monitor 24 hours a day, which is inconvenient for the user to use.

[0003] In order to facilitate users to measure blood pressure, wearable devices (such as watches) have been equipped with blood pressure detection devices. Users can use the wearable devices to perform dynamic blood pressure measurement, saving time and effort. Users can set blood pressure measurement plans on wearable devices, such as setting the time for blood pressure measurement and the time interval between two adjacent blood pressure measurements. However, it is cumbersome for users to manually set blood pressure measurement plans. How to save user operations needs further research. Summary of the invention

[0004] The present application provides a blood pressure measurement scheme generation method, an electronic device and a storage medium, which enable a wearable device to automatically generate a blood pressure measurement scheme for a user, so that the blood pressure measurement scheme generated by the wearable device is more in line with the user's characteristics and living habits, and improves the rationality of blood pressure measurement.

[0005] In a first aspect, the present application provides a method for generating a blood pressure measurement scheme, the method comprising: a wearable device obtains one or more of user information, physiological data and device status; the wearable device generates a blood pressure measurement scheme based on one or more of the user information, physiological data and device status, the blood pressure measurement scheme comprising one or more of the following: the start time of the blood pressure measurement, the end time of the blood pressure measurement, the duration of the blood pressure measurement, the number of blood pressure measurements within the duration of the blood pressure measurement, the time interval between two adjacent blood pressure measurements within the duration of the blood pressure measurement, and the total number of blood pressure measurements; the wearable device obtains the blood pressure measurement value of the user within a blood pressure measurement cycle based on the blood pressure measurement scheme.

[0006] For example, a blood pressure measurement cycle may be a 24-hour cycle.

[0007] Through this method, the wearable device can automatically generate a blood pressure measurement plan based on the fusion of multiple information, so that the blood pressure measurement plan generated by the wearable device is more in line with the user's characteristics, which not only saves user operations but also improves the rationality of blood pressure measurement.

[0008] In combination with the first aspect, in one possible implementation, user information includes one or more of the following: gender, age, height, weight, smoking history, drinking history, medical history, medication history, and living habits; physiological data includes one or more of the following: heart rate, blood pressure, arteriosclerosis, and blood sugar; device status includes one or more of the following: remaining power and device temperature.

[0009] In combination with the first aspect, in a possible implementation method, the wearable device generates a blood pressure measurement plan based on one or more of user information, physiological data and device status, specifically including: the wearable device determines the risk level of the user's hypertension risk based on one or more of user information, physiological data and device status; the wearable device generates a blood pressure measurement plan based on the user's hypertension risk level.

[0010] Different blood pressure measurement schemes are generated for different risk levels of hypertension risk. For example, the total number of blood pressure measurements determined by the wearable device based on high risk is greater than the total number of blood pressure measurements determined by the wearable device based on low risk.

[0011] In some embodiments, the risk level of hypertension risk may refer to the risk level in a certain time period within a blood pressure measurement cycle. For example, the risk level of hypertension risk of a user in the night time period is greater than the risk level of hypertension risk of the user in the day time period. Then the total number of blood pressure measurements in the night time period is greater than the total number of blood pressure measurements in the day time period.

[0012] In this way, the wearable device can determine the risk level of the user's hypertension risk based on a variety of information, and then generate a blood pressure measurement plan based on the risk level of hypertension risk.

[0013] In combination with the first aspect, in a possible implementation, after the wearable device generates a blood pressure measurement plan, the method also includes: the wearable device displays a first prompt message, and the first prompt message is used to prompt the user to view the details of the blood pressure measurement plan; the wearable device receives and responds to the user's first operation on the first option in the first prompt message, and displays a first user interface, in which the details of the blood pressure measurement plan are displayed.

[0014] In this way, after the wearable device automatically generates a blood pressure measurement plan, the wearable device can prompt the user to view the details of the blood pressure measurement plan. In some embodiments, the wearable device can also receive user operations to modify the blood pressure measurement plan.

[0015] In combination with the first aspect, in a possible implementation, before the wearable device measures and obtains the blood pressure measurement value of the user within a blood pressure measurement cycle based on the blood pressure measurement scheme, the method also includes: the wearable device obtains the remaining power of the wearable device; when the remaining power of the wearable device is less than a preset power, the wearable device displays a second prompt message, and the second prompt message is used to prompt the user to charge the wearable device, wherein the preset power is the minimum power required for the wearable device to complete the blood pressure measurement within a blood pressure measurement cycle based on the blood pressure measurement scheme; when the wearable device is in a charging state within a first period of time after the second prompt message is displayed, the blood pressure measurement scheme is saved.

[0016] In this way, before the wearable device measures blood pressure based on the automatically generated blood pressure measurement plan, the device needs to determine whether the remaining power of the wearable device is sufficient. This prevents the wearable device from shutting down before completing a blood pressure measurement cycle. After the wearable device displays a prompt message and is in a charging state, the wearable device can save the blood pressure measurement plan and complete the blood pressure measurement within a blood pressure measurement cycle based on the blood pressure measurement plan.

[0017] In combination with the first aspect, in a possible implementation, the method also includes: when the wearable device is not in a charging state within a first period of time after displaying the second prompt information, the wearable device displays a third prompt information, and the third prompt information is used to prompt the user to change the blood pressure measurement plan; the wearable device receives and responds to the user's second operation on the second option in the third prompt information, obtains and saves a first updated blood pressure measurement plan, and the total number of blood pressure measurements in the first updated blood pressure measurement plan is less than the total number of blood pressure measurements in the blood pressure measurement plan; the wearable device obtains the user's blood pressure measurement value in a blood pressure measurement cycle based on the first updated blood pressure measurement plan.

[0018] Optionally, the power required by the first updated blood pressure measurement scheme to complete blood pressure measurement within a blood pressure measurement cycle is less than or equal to the remaining power of the wearable device.

[0019] In this way, when the wearable device is still not in the charging state after the wearable device displays the prompt information, the wearable device can prompt the user again to modify the blood pressure measurement plan and obtain the first updated blood pressure measurement plan.

[0020] In combination with the first aspect, in a possible implementation, the method also includes: the wearable device receives and responds to the user's third operation on the third option in the third prompt information, displays a fourth prompt information, and the fourth prompt information is used to prompt the user to set the wearable device to a low power consumption mode; the wearable device receives and responds to the user's fourth operation on the fourth option in the fourth prompt information, and enters a low power consumption mode.

[0021] Optionally, the low power consumption mode may refer to shutting down some or all energy-consuming operations on the wearable device 100 that are not related to blood pressure monitoring. For example, energy-consuming operations may include but are not limited to heart rate monitoring functions, exercise data recording functions, etc.

[0022] In this way, if the user still does not modify the blood pressure measurement plan after the wearable device displays the prompt information, the wearable device can prompt the user again to control the wearable device to enter the low power consumption mode in order to save the power of the device.

[0023] In combination with the first aspect, in a possible implementation, the method also includes: the wearable device receives and responds to the user's fifth operation on the fifth option in the fourth prompt information, and displays a fifth prompt information, where the fifth prompt information is used to prompt the user that the battery of the wearable device is too low.

[0024] In this way, if the wearable device has not entered the low power consumption mode after the wearable device displays the prompt information, the wearable device can remind the user that the battery of the device is too low and may be shut down at any time.

[0025] In combination with the first aspect, in a possible implementation, the blood pressure measurement value includes a first blood pressure measurement value obtained by the wearable device at a first moment; after the wearable device obtains the first blood pressure measurement value, the method further includes: the wearable device obtains a current user state; when the current user state meets the blood pressure measurement condition, the wearable device saves the first blood pressure measurement value

[0026] In a possible implementation, the method also includes: when the current user state does not meet the blood pressure measurement conditions, the wearable device obtains a blood pressure compensation value based on the current user state; the wearable device obtains a first blood pressure monitoring value based on the blood pressure compensation value and the first blood pressure measurement value; and the wearable device saves the first blood pressure monitoring value.

[0027] The blood pressure measurement conditions may include but are not limited to one or more of the following: the user is in a stationary state, and the difference between the real-time heart rate and the nighttime static heart rate is within a preset range.

[0028] Wearable devices can collect motion data based on motion sensors. Motion sensors can include but are not limited to: acceleration sensors, gyroscope sensors, etc. Motion sensors can collect motion data or motion trajectories. Wearable devices can determine whether the user is in a stationary state based on the motion data or motion trajectory.

[0029] In this way, when measuring blood pressure, the wearable device can determine whether the user's state meets the blood pressure measurement conditions. If the conditions are met, the blood pressure measurement results can be directly saved. If not, the wearable device needs to correct the blood pressure measurement results and then save the corrected blood pressure measurement results, which can improve the accuracy of blood pressure measurement.

[0030] In combination with the first aspect, in a possible implementation, the method also includes: the wearable device obtains historical blood pressure measurement data, wherein the historical blood pressure measurement data includes historical blood pressure measurement records and historical blood pressure measurement results; the wearable device updates the blood pressure measurement scheme based on the historical blood pressure measurement data, generates and saves a second updated blood pressure measurement scheme; the wearable device obtains the blood pressure measurement value of the user within a blood pressure measurement cycle based on the second updated blood pressure measurement scheme.

[0031] The historical blood pressure measurement records include but are 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 of the historical blood pressure measurement, the end time of the historical blood pressure measurement, the duration of the historical blood pressure measurement, the number of blood pressure measurements within the duration of the historical blood pressure measurement, the time interval between two adjacent blood pressure measurements within the duration of the historical blood pressure measurement, the total number of historical blood pressure measurements, etc.

[0032] In this way, the wearable device can periodically / irregularly update the blood pressure measurement solution based on the user's historical data to improve the accuracy of the blood pressure measurement solution generated by the wearable device.

[0033] In a second aspect, the present application provides a wearable device, which includes a memory and a processor; wherein the memory and the processor are coupled, and the memory is used to store a computer program. When the processor executes and calls the computer program, the wearable device executes a blood pressure measurement scheme generation method provided in any possible implementation of any of the above aspects.

[0034] In a third aspect, the present application provides a computer-readable storage medium comprising instructions. When the instructions are executed on a wearable device, the wearable device executes a blood pressure measurement scheme generating method provided in any possible implementation of any of the above aspects.

[0035] In a fourth aspect, the present application provides a chip system, the chip system comprising one or more processors, the processor being used to call computer instructions to execute a blood pressure measurement scheme generating method provided in any possible implementation of any of the above aspects.

When the above-mentioned computer program product is run on a wearable device, the wearable device executes a blood pressure measurement scheme generating method provided in any possible implementation of any of the above-mentioned aspects.

[0037] For the description of the beneficial effects of the second to fifth aspects, reference may be made to the description of the beneficial effects in the first aspect, and this application will not repeat them here. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] The technical solutions in the embodiments of the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0057] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features, and in the description of the embodiments of the present application, unless otherwise specified, "plurality" means two or more.

[0058] The term "user interface (UI)" in the following embodiments of the present application refers to a medium interface for interaction and information exchange between an application or operating system and a user, which realizes the conversion between the internal form of information and the form acceptable to the user. A common form of user interface is a graphical user interface (GUI), which refers to a user interface related to computer operation displayed in a graphical manner. It can be a visual interface element such as text, icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, widgets, etc. displayed on the display screen of an electronic device.

[0059] With the development of electronic technology, the functions of wearable devices are constantly enhanced. For example, wearable devices such as bracelets and watches can provide blood pressure measurement functions, helping users to measure their blood pressure anytime and anywhere, and then understand their physical condition. Users can wear wearable devices on their wrists to conveniently monitor their blood pressure in real time.

[0060] Next, a wearable device 100 provided in the present application and usable for measuring blood pressure is introduced.

[0061] Figure 1 A schematic diagram showing a user wearing a wearable device 100 is shown.

[0062] like Figure 1 As shown, the user can wear the wearable device 100 on the user's wrist.

[0063] Figure 2 A schematic diagram of the structure of the wearable device 100 is shown.

[0064] like Figure 2 As shown, the wearable device 100 may include a watch body 201 and a wearable component 202 .

[0065] The watch body 201 is provided with a motion sensor, such as a gyroscope sensor and an acceleration sensor, and the motion sensor is used to collect motion data and determine whether the user is in a sleeping state based on the motion state obtained by analyzing the motion data.

[0066] The watch body 201 may include a display screen 203. The display screen 203 may be used to display the time, the power level of the watch body 201, the Bluetooth logo, received messages, and user motion data. The display screen 203 may be used to receive a user click operation to light up the display screen, start and end a motion mode, and the like. The display screen 203 may also record the number of steps moved by the user, the calories consumed, and may have basic functions such as call reminders and message notifications. In a possible implementation, the watch body 201 may establish a wireless communication connection with the wearable device 100 via Bluetooth. The watch body 201 may send the user's motion data to the wearable device 100 to which the connection is established. Furthermore, when the wearable device 100 receives an incoming call or message notification, the watch body 201 may receive an instruction from the mobile phone to remind the user that there is an incoming call or message notification.

[0067] The wearable component 202 is used to mount the watch body 201. For example, the wearable component 202 may be a device such as a wristband or a watch strap. The wearable component 202 is a device that allows the device watch body 201 to be attached to the user's wrist. The wearable device 100 is attached to the user's wrist, so that the inertial sensor can collect the motion data of the user's wrist to monitor the movement of the user's wrist to determine the user's posture.

[0068] When the wearable device 100 starts to measure blood pressure, the wearable device 100 can control the wearable component 202 to contract and then relax to measure the user's blood pressure.

[0069] In some embodiments, the process of measuring blood pressure by the wearable device 100 may include: first, the wearable device 100 inflates the wearable component 202 to temporarily block the arm artery, and then, in the process of slowly deflation, records the air pressure value of the wearable component 202 and the pulse signal generated by the pulse; finally, the user's blood pressure is determined based on the air pressure value of the wearable component 202 and the amplitude or envelope of the pulse signal. Among them, blood flow will generate lateral pressure on the blood vessel wall, and the change in the magnitude of the lateral pressure will cause the blood vessel wall to vibrate slightly, and the pulse signal is a signal generated by the slight vibration of the blood vessel wall. Among them, determining the user's blood pressure based on the air pressure value of the wearable component 202 and the amplitude or envelope of the pulse signal is also called an oscillometric method.

[0070] In other embodiments, the process of measuring blood pressure by the wearable device 100 may include: the wearable device 100 may gradually inflate the wearable component 202 so that the arm artery is blocked by the component until it is completely blocked, record the air pressure value of the wearable component 202 and the pulse signal generated by the pulse, and then determine the user's blood pressure based on the air pressure value of the wearable component 202 and the amplitude or envelope of the pulse signal, and finally deflate. Among them, blood flow will generate lateral pressure on the blood vessel wall, and changes in the magnitude of the lateral pressure will cause the blood vessel wall to vibrate slightly, and the pulse signal is a signal generated by the slight vibration of the blood vessel wall. Among them, determining the user's blood pressure based on the air pressure value of the wearable component 202 and the amplitude or envelope of the pulse signal is also called the oscillometric method.

[0071] Figure 3A An exemplary schematic diagram of the principle of the oscillometric method provided in an embodiment of the present application.

[0072] like Figure 3A As shown, in the process of the wearable device 100 inflating the wearable component 202 to temporarily block the arm artery, the state of the wearable component 202 is gradually increasing the pressure to stability, and the artery state is gradually blocked to completely blocked; then in the process of slowly deflation, the state of the wearable component 202 is gradually decreasing the pressure to 0, and the artery state is completely blocked to unblocked. In the process of the wearable component 202 gradually decreasing the pressure to 0, the air pressure value and pulse signal of the wearable component 202 are recorded. When the air pressure value of the wearable component 202 is greater than or equal to the systolic pressure, the artery is blocked and the pulse signal is a small oscillation wave; when the air pressure value of the wearable component 202 gradually decreases and is less than the systolic pressure and greater than the mean pressure, the artery is gradually unblocked and the amplitude of the pulse signal continues to increase; when the air pressure value of the wearable component 202 is equal to the mean pressure, the amplitude of the pulse signal reaches the maximum value; when the air pressure value of the wearable component 202 continues to gradually decrease and is greater than the diastolic pressure and less than the mean pressure, the amplitude of the pulse signal gradually decreases; when the air pressure value of the wearable component 202 is less than the diastolic pressure, the pulse signal is a small oscillation wave. Therefore, the wearable device 100 can determine the user's systolic and diastolic pressures through the amplitude changes of the pulse signal and the air pressure value of the wearable component 202. In a possible implementation, the air pressure value of the wearable component 202 and the pulse signal can be determined by the air pressure sensor built into the wearable device 100.

[0073] Figure 3B Another exemplary schematic diagram of the principle of the oscillometric method provided in an embodiment of the present application.

[0074] like Figure 3BAs shown, in the process of the wearable device 100 inflating the wearable component 202 to temporarily block the arm artery, the state of the wearable component 202 is gradually increasing pressure to stability, and the artery state is gradually blocked to complete blockage. In the process of the wearable component 202 being gradually pressurized to stability, the air pressure value and pulse signal of the wearable component 202 are recorded. When the air pressure value of the wearable component 202 gradually increases and the diastolic pressure is less than the mean pressure, the pulse signal is a small oscillation wave. When the air 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, and when the air pressure value of the wearable component 202 is equal to the mean pressure, the amplitude of the pulse signal reaches the maximum value. When the air pressure value of the wearable component 202 gradually increases and is greater than the mean pressure and less than the systolic pressure, the artery is gradually blocked, and the amplitude of the pulse signal continues to decrease; when the air pressure value of the wearable component 202 is greater than or equal to the systolic pressure, the artery is blocked, and the pulse signal is a small oscillation wave. Therefore, the wearable device 100 can determine the user's systolic and diastolic blood pressures through the amplitude change of the pulse signal and the air pressure value of the wearable component 202. In a possible implementation, the air pressure value of the wearable component 202 and the pulse signal can be determined by a built-in air pressure sensor in the wearable device 100.

[0075] Figure 4A A schematic diagram of the hardware structure of the wearable device 100 is shown.

[0076] like Figure 4A As shown, the wearable device can be a wearable device such as a bracelet, a watch, etc., and the wearable device 100 can also be a non-wearable device such as a wall-type blood pressure monitor, etc. The embodiment of the present application does not impose any special restrictions on the specific type of the wearable device. The embodiment of the present application is only described by taking the wearable device 100 as a watch as an example.

[0077] 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 screen 205, a motor 206, an internal memory 207, a SIM card interface 208, a USB interface 209, a power management module 210, a battery 211, and a charging management module 212. Among them, the sensor module 203 may include a touch sensor 203A, an air pressure sensor 203B, an air pump 203C, an airbag 203D, a magnetic sensor 203E, a photoplethysmography (PPG) sensor 203F and a motion sensor 203G, and an air path conducting component 203H. Among them, the airbag 203D has a similar function to the wearable component 202.

[0078] It is understood that the structure illustrated in the embodiment of the present invention does not constitute a specific limitation on the wearable device. In other embodiments of the present application, the wearable device may include more or fewer components than shown in the figure, or combine certain components, or split certain components, or arrange the components differently. The components shown in the figure may be implemented in hardware, software, or a combination of software and hardware.

[0079] The processor 200A may include one or more processing units, for example, the processor 200A may include an application processor (AP), a modem processor, a graphics processor (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), etc. Different processing units may be independent devices or integrated into one or more processors.

[0080] In some embodiments, the processor 200A may include one or more interfaces. The interface 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, and / or a universal serial bus (USB) interface, etc.

[0081] In some embodiments, the processor 200A may also be a microprocessor unit (MCU).

[0082] The I2C interface is a bidirectional synchronous serial bus, including 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 coupled to the touch sensor 203A, the power management module 210, etc. through different I2C bus interfaces. For example, the processor 200A may be coupled to the touch sensor 203A through the I2C interface, so that the processor 200A communicates with the touch sensor 203A through the I2C bus interface, thereby realizing the touch function of the wearable device.

[0083] The I2S interface can be used for audio communication. The PCM interface can also be used for audio communication to sample, quantize and encode analog signals. The UART interface is a universal serial data bus for asynchronous communication. The bus can be a bidirectional communication bus. It converts the data to be transmitted between serial communication and parallel communication. In some embodiments, the UART interface is generally used to connect the processor 200A with the wireless communication module 201. For example, the processor 200A communicates with the Bluetooth module in the wireless communication module 201 through the UART interface to implement the Bluetooth function.

[0084] The MIPI interface can be used to connect the processor 200A with peripheral devices such as the display screen 205. The MIPI interface includes a camera serial interface (CSI), a display serial interface (DSI), etc. The processor 200A and the display screen 205 communicate through the DSI interface to realize the display function of the wearable device.

[0085] The GPIO interface can be configured by software. The GPIO interface can be configured as a control signal or as a data signal. The USB interface 209 is an interface that complies with the USB standard specification, and can specifically be a Mini USB interface, a Micro USB interface, a USB Type C interface, etc. The USB interface 209 can be used to connect a charger to charge the wearable device, and can also be used to transmit data between the wearable device and peripheral devices.

[0086] It is understandable that the interface connection relationship between the modules illustrated in the embodiment of the present invention is only a schematic illustration and does not constitute a structural limitation on the wearable device. In other embodiments of the present application, the wearable device may also adopt different interface connection methods in the above embodiments, or a combination of multiple interface connection methods.

[0087] The charging management module 212 is used to receive charging input from a charger. The charger can be a wireless charger or a wired charger. In some wired charging embodiments, the charging management module 212 can receive charging input from the wired charger through the USB interface 209. In some wireless charging embodiments, the charging management module 212 can receive wireless charging input through the wireless charging coil of the wearable device. While the charging management module 212 is charging the battery 211, it can also power the wearable device through the power management module 210.

[0088] The power management module 210 is used to connect the battery 211, the charging management module 212 and the processor 200A.

[0101] The air pressure sensor 203B is used to measure air pressure. In some embodiments of the present application, the wearable device measures the air pressure in the airbag 203D through the air pressure sensor 203B. In some embodiments of the present application, a part of the air pressure sensor 203B is located inside the airbag 203D to sense the air pressure of the airbag 203D.

[0102] The air pump 203C is used for inflation and deflation. In some embodiments of the present application, the wearable device inflates the airbag 203D through the air pump 203C, wherein the air pump 203C and the airbag 203D are connected through the air path conducting component 203H. The airbag 203D is used to squeeze the user's blood vessels.

[0103] The magnetic sensor 203E includes a Hall sensor. In some embodiments of the present application, the wearable device can use the magnetic sensor 203F to determine whether the airbag 203D on the wearable device is disassembled. For example, a magnet can be configured on the airbag 203D or on a strap connected to the airbag 203D, and the wearable device can determine the magnetic flux generated by the magnet on the airbag 203D or on the airbag 203D through the magnetic sensor, and then determine whether the airbag 203D on the wearable device is disassembled.

[0104] The PPG sensor 203F user obtains the user's health data based on the PPG signal collected by the PPG sensor 203F. The user's health data includes but is not limited to: heart rate, blood oxygen, respiratory rate, blood oxygen saturation (SaO2), etc.

[0105] The motion sensor 203G includes but is not limited to an acceleration sensor and an angular velocity sensor. The motion sensor 203G can be used to collect motion data, and determine the user's motion state based on the motion data, and then determine whether the user is in a sleeping state based on the user's motion state.

[0106] It is worth noting that the air path conducting component 203H can be a separate component, or the air path conducting component 203H can also be an air path formed by the combination of other hardware modules, or the air path conducting component 203H can also be a part of other components, for example, it can be a part of the air pump 203C, or it can be a part of the airbag 203D.

[0107] It is worth noting that the sensor module 203 may also include an acceleration sensor, an infrared sensor, and the like.

[0108] like Figure 4B As shown, when the wearable device 100 is a watch, the airbag 203D is attached to the side of the wearable component 202 close to the body. The air pump 203C is connected to the airbag 203D through the air path conducting component 203H. The airbag 203D can be attached to only one side of the wearable component 202, and the wearable component 202 on this side can be located above the artery position of the user's wrist, such as above the radial artery position.

[0110] Currently, the user can set a blood pressure measurement plan on the wearable device 100 .

[0111] A blood pressure measurement plan may include one or more blood pressure measurement strategies, which may include but are not limited to: the start time of the blood pressure measurement, the end time of the blood pressure measurement, the duration of the blood pressure measurement, the number of blood pressure measurements within the duration of the blood pressure measurement, the time interval between two adjacent blood pressure measurements within the duration of the blood pressure measurement, the total number of blood pressure measurements, etc.

[0112] The start time of blood pressure measurement may refer to the time of day at which the user's blood pressure is measured. For example, the start time of blood pressure measurement may be 9 o'clock in the morning or 10 o'clock in the evening.

[0113] The end time of blood pressure measurement may refer to the time in a day when the user's blood pressure measurement stops. For example, the end time of blood pressure measurement may be 12 o'clock noon or 6 o'clock in the morning.

[0114] The duration of blood pressure measurement may refer to the time between which the user's blood pressure is measured in a day. The duration of blood pressure measurement in a day may include one or more time periods. For example, the duration of blood pressure measurement may be from 9 am to 12 pm, and / or from 10 pm to 6 am the next day.

[0115] The blood pressure measurement frequency within the duration of the blood pressure measurement may refer to the total number of times the blood pressure is measured within a duration of the blood pressure measurement. For example, when the duration of the blood pressure measurement is from 9 a.m. to 12 p.m., the blood pressure measurement frequency is 6 times. When the duration of the blood pressure measurement is from 10 p.m. to 6 a.m. the next day, the blood pressure measurement frequency is 30 times.

[0116] The time interval between two adjacent blood pressure measurements within the duration of blood pressure measurement may refer to the time difference between two adjacent blood pressure measurements within a duration of blood pressure measurement. Within a duration of blood pressure measurement, the time difference between two adjacent blood pressure measurements may be the same or different. For example, when the duration of blood pressure measurement is from 9 am to 12 noon, the time difference between two adjacent blood pressure measurements may be 30 minutes.

[0117] The total number of blood pressure measurements may refer to the total number of blood pressure measurements within 24 hours in a day between 0:00 am and 12:00 pm. For example, the total number of blood pressure measurements in a day may be 36 times.

[0118] The blood pressure measurement scheme is not limited to the above blood pressure measurement strategies, and the blood pressure measurement scheme may also include other blood pressure measurement strategies, which are not limited in this application.

[0119] Figure 5A-5D A schematic diagram showing a user manually setting a blood pressure measurement plan.

[0120] For example, the wearable device 100 may display Figure 5A User interface 510 is shown. Option 501 and option 502 are shown in user interface 510. The user can manually set the blood pressure measurement plan through option 501 and option 502.

[0121] For example, Figure 5A As shown, the wearable device 100 can receive a user input operation (such as a single click) for option 501 in the user interface 510, and in response to the user input operation, the wearable device 100 can display Figure 5B User interface 520 is shown. User interface 520 shows some blood pressure measurement strategies of the blood pressure measurement scheme, for example, the user can manually set the time interval between two adjacent blood pressure measurements during the day and the time interval between two adjacent blood pressure measurements at night. Exemplarily, the time interval between two adjacent blood pressure measurements during the day set by the user is 30 minutes, and the time interval between two adjacent blood pressure measurements at night set by the user is also 30 minutes.

[0122] In addition to setting the time interval for blood pressure measurement, the wearable device 100 can also receive user operations to set other blood pressure measurement strategies, which is not limited in this application.

[0123] Afterwards, the wearable device 100 can receive the user's input operation (such as a single click) for starting to measure blood pressure in the user interface 520. In response to the user's input operation, the wearable device 100 can save the blood pressure measurement plan set by the user and start measuring the user's blood pressure when the conditions of the blood pressure measurement plan are met.

[0124] For example, Figure 5C As shown, the wearable device 100 can receive a user input operation (such as a click) for option 502 in the user interface 510, and in response to the user input operation, the wearable device 100 can display Figure 5D User interface 530 is shown. User interface 530 shows a partial blood pressure measurement strategy of a blood pressure measurement scheme, which may be preset, for example, the preset blood pressure measurement scheme includes the time interval between two adjacent blood pressure measurements during the day and the time interval between two adjacent blood pressure measurements at night. Exemplarily, 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.

[0125] Afterwards, the wearable device 100 can receive the user's input operation (such as a single click) for starting to measure blood pressure in the user interface 530. In response to the user's input operation, the wearable device 100 can save the preset blood pressure measurement scheme and start measuring the user's blood pressure when the conditions of the preset blood pressure measurement scheme are met.

[0126] It should be noted that Figure 5A-5D Only a schematic diagram of manually creating a blood pressure measurement plan is shown. The user can manually create a blood pressure measurement plan in other ways, which is not limited in this application.

[0127] from Figure 5A-5D It can be seen that the blood pressure measurement schemes all need to be manually created or manually set by the user to take effect, which is cumbersome for the user to operate, and the blood pressure measurement schemes manually created or manually set by the user may not meet the needs of the user, resulting in a poor user experience.

[0128] Based on this, the present application provides a method for generating a blood pressure measurement plan, and the wearable device 100 can automatically generate a blood pressure measurement plan based on one or more of user information, physiological data, and device status, etc. The user does not need to manually create a blood pressure measurement plan, saving user operations.

[0129] A blood pressure measurement plan may include one or more blood pressure measurement strategies, which may include but are not limited to: the start time of the blood pressure measurement, the end time of the blood pressure measurement, the duration of the blood pressure measurement, the number of blood pressure measurements within the duration of the blood pressure measurement, the time interval between two adjacent blood pressure measurements within the duration of the blood pressure measurement, the total number of blood pressure measurements, etc.

[0130] The cycle of the blood pressure measurement scheme can be a day (24 hours) or other cycles, which is not limited in this application.

[0131] Among them, user information includes but is not limited to one or more of the following: gender, age, height, weight, whether to smoke, whether to drink, medical history, whether to take medicine, living habits and other information.

[0132] Physiological data includes but is not limited to one or more of the following: heart rate, blood pressure, arteriosclerosis, blood sugar, etc.

[0133] The device status includes but is not limited to one or more of the following: remaining battery power, device temperature, etc.

[0134] The wearable device 100 can determine the user's hypertension risk based on user information, physiological data, device status, and other information, and obtain a blood pressure measurement plan based on the user's hypertension risk. Different blood pressure measurement plans are obtained for different hypertension risks.

[0135] Optionally, the blood pressure measurement plan may refer to a blood pressure measurement plan within one day (24 hours).

[0136] Optionally, different users have different user information, physiological data and device status, and the wearable device 100 obtains different blood pressure measurement solutions.

[0137] For example, when it is determined that the user's hypertension risk is high risk, the measurement mode of the blood pressure measurement scheme obtained by the wearable device 100 may be a high-frequency measurement mode.

[0138] When it is determined that the user's hypertension risk is low, the measurement mode of the blood pressure measurement solution obtained by the wearable device 100 may be a low-frequency measurement mode.

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

[0140] Optionally, the total number of blood pressure measurements may refer to the total number of blood pressure measurements within one day (24 hours).

[0141] In other embodiments, the high-frequency measurement mode and the low-frequency measurement mode may also be measurement modes within a certain time period.

[0142] For example, when it is determined that the user's hypertension risk is high only in the first time period, the wearable device 100 can measure the user's blood pressure in a high-frequency measurement mode only in the first time period, and measure the user's blood pressure in a low-frequency measurement mode in non-first time periods.

[0143] For example, when it is determined that the user's hypertension risk is high only between 8 a.m. and 12 a.m., and the user's hypertension risk is low between 0 a.m. and 8 a.m. and between 12 a.m. and 12 p.m., the wearable device 100 can measure the user's blood pressure in a high-frequency measurement mode only between 8 a.m. and 12 a.m., and measure the user's blood pressure in a low-frequency measurement mode between 0 a.m. and 8 a.m. and between 12 a.m. and 12 p.m.

[0144] In some embodiments, the wearable device 100 can further divide the high risk of hypertension into different high risk levels, and start different measurement modes based on different high risk levels.

[0145] For example, high risk can be further divided into first-level risk and second-level risk, and first-level risk is greater than second-level risk. Not limited to two levels, high risk can also be divided into other more levels, which is not limited in this application.

[0146] When it is determined that the user's hypertension risk in the first time period is a first level risk and the hypertension risk in the second time period is a second level risk, the wearable device 100 can measure the user's blood pressure in the first time period in a first high-frequency measurement mode and in the second time period in a second high-frequency measurement mode. The total number of blood pressure measurements in the first high-frequency measurement mode is greater than the total number of blood pressure measurements in the second high-frequency measurement mode.

[0147] For example, when it is determined that the user's hypertension risk is a first level risk between 8 a.m. and 10 a.m., the user's hypertension risk is a second level risk between 10 a.m. and 12 a.m., and the user's hypertension risk is a low risk between 0 a.m. and 8 a.m. and between 12 a.m. and 12 p.m., the wearable device 100 can measure the user's blood pressure in a first high-frequency measurement mode between 8 a.m. and 10 a.m., measure the user's blood pressure in a second high-frequency measurement mode between 10 a.m. and 12 a.m., and measure the user's blood pressure in a low-frequency measurement mode between 0 a.m. and 8 a.m. and between 12 a.m. and 12 p.m.

[0148] In some embodiments, the wearable device 100 can determine the start time of blood pressure measurement based on the user's living habits.

[0149] The wearable device 100 can determine the user's living habits based on the collected user data, such as the user's historical travel data, historical riding records and other user data, and then determine the start time of blood pressure measurement based on the user's living habits to avoid disturbing the user's daily activities.

[0150] For example, based on the collected user data, the wearable device 100 can determine that the user is on the way to work between 7:00 and 8:30 a.m., then the start time of the blood pressure measurement in the blood pressure measurement scheme determined by the wearable device 100 can avoid the period between 7:00 and 8:30 a.m.

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

[0152] Figure 6A-6B FIG. 4 is a schematic diagram showing a wearable device 100 recommending a blood pressure measurement solution to a user.

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

[0154] like Fig. 6A As shown, the wearable device 100 may display a prompt bar 601, which includes a prompt message "Do you want to save and use the blood pressure measurement plan?" The prompt bar 601 is used to prompt the user to view the details of the blood pressure measurement plan.

[0155] Among them, the prompt bar 601 includes option 602, option 603 and option 604. Among them, the wearable device 100 can receive the user's input operation (such as a single click) for option 602, and in response to the user's input operation, the wearable device 100 can display the details of blood pressure measurement solution one. The wearable device 100 can also receive the user's input operation (such as a single click) for option 603, and in response to the user's input operation, the wearable device 100 can display the details of blood pressure measurement solution two. The wearable device 100 can also receive the user's input operation (such as a single click) for option 604, and in response to the user's input operation, the wearable device 100 can display the details of blood pressure measurement solution three.

[0156] For example, Fig. 6A As shown, the wearable device 100 can receive a user input operation (such as a click) for option 604 in the prompt bar 601, and in response to the user's input operation, the wearable device 100 can display Figure 6B The prompt bar 605 shown shows the details of the blood pressure measurement scheme three. For example, the details of the blood pressure measurement scheme three may include: the time interval between two adjacent blood pressure measurements during the day is 30 minutes, and the time interval between two adjacent blood pressure measurements at night is also 30 minutes. The user can view the details of the blood pressure measurement scheme three in the prompt bar 605. The prompt bar 605 also includes a confirmation option and a modification option. Among them, the user can save the blood pressure measurement scheme three through the confirmation option. The user can also modify the blood pressure measurement scheme three through the modification option, and then save the modified blood pressure measurement scheme three.

[0157] The wearable device 100 prompts the user to change the blood pressure measurement plan based on the remaining power.

[0158] In some embodiments, after the wearable device 100 determines and saves the blood pressure measurement plan, before the wearable device 100 uses the blood pressure measurement plan, the wearable device 100 can determine the minimum power required for the blood pressure measurement plan, and compare the minimum power required for the blood pressure measurement plan with the remaining power of the wearable device 100 to determine whether the saved blood pressure measurement plan needs to be changed, so as to avoid the situation where the wearable device 100 is too low in power and shuts down and cannot measure blood pressure.

[0159] Figure 7 A schematic flow chart of a method in which the wearable device 100 prompts a user to change a blood pressure measurement scheme based on the remaining power is shown.

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

[0161] Among them, user information includes but is not limited to one or more of the following: gender, age, height, weight, whether to smoke, whether to drink, medical history, whether to take medication, etc.

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

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

[0164] The wearable device 100 can determine the user's hypertension risk based on user information, physiological data, device status, and other information, and obtain a blood pressure measurement plan based on the user's hypertension risk. Different blood pressure measurement plans are obtained for different hypertension risks.

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

[0166] A blood pressure measurement plan may include one or more blood pressure measurement strategies, which may include but are not limited to: the start time of the blood pressure measurement, the end time of the blood pressure measurement, the duration of the blood pressure measurement, the number of blood pressure measurements within the duration of the blood pressure measurement, the time interval between two adjacent blood pressure measurements within the duration of the blood pressure measurement, the total number of blood pressure measurements, etc.

[0167] Optionally, the blood pressure measurement plan may refer to a blood pressure measurement plan within one day (24 hours).

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

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

[0170] When it is determined that the user's hypertension risk is low, the measurement mode of the blood pressure measurement solution obtained by the wearable device 100 may be a low-frequency measurement mode.

[0171] The total number of blood pressure measurements in the high-frequency measurement mode is greater than the total number of blood pressure measurements in the low-frequency measurement mode.

[0172] In other embodiments, the blood pressure measurement scheme may also be determined by other devices (such as mobile phones or servers) that establish a communication connection with the wearable device 100 and then sent to the wearable device 100.

[0173] S703: The wearable device 100 determines a minimum power level based on the blood pressure measurement solution.

[0174] The minimum amount of power may be the minimum amount of power required to complete the total number of blood pressure measurements in a blood pressure measurement regimen in one day.

[0175] After the wearable device 100 obtains the blood pressure measurement plan, the wearable device 100 can estimate the minimum power required to complete the total number of blood pressure measurements in a day based on the blood pressure measurement plan to meet the blood pressure measurement plan requirements for high-frequency blood pressure start-up measurements.

[0176] Optionally, the wearable device 100 can estimate the minimum power required to complete the total number of blood pressure measurements in a day based on the average power required to complete a blood pressure measurement and the total number of blood pressure measurements in the blood pressure measurement scheme.

[0177] S704: The wearable device 100 determines whether the minimum power level is greater than the remaining power level of the wearable device 100.

[0178] The wearable device 100 may obtain the remaining power of the wearable device 100 , and determine whether the minimum power is greater than the remaining power of the wearable device 100 .

[0179] If it is determined that the lowest power level is greater than the remaining power level of the wearable device 100, S705 is executed.

[0180] If it is determined that the lowest power level is less than the remaining power level of the wearable device 100, S706 is executed.

[0181] S705: The wearable device 100 saves the blood pressure measurement plan.

[0182] When it is determined that the minimum power is greater than the remaining power of the wearable device 100, the remaining power of the wearable device 100 can complete the minimum power required for the total number of blood pressure measurements in the blood pressure measurement plan within one day, and the wearable device 100 saves the blood pressure measurement plan.

[0183] In some embodiments, before the wearable device 100 saves the blood pressure measurement scheme, the wearable device 100 may display Figure 6A-6B The user interface shown in the figure prompts the user to view the blood pressure measurement plan. The user can also actively modify the blood pressure measurement plan and save the modified blood pressure measurement plan.

[0184] S706: The wearable device 100 prompts the user to charge and determines whether to charge.

[0185] When it is determined that the minimum power is less than the remaining power of the wearable device 100, the remaining power of the wearable device 100 cannot complete the minimum power required for the total number of blood pressure measurements in the blood pressure measurement plan within one day, and the wearable device 100 can prompt the user to charge the wearable device 100.

[0186] If it is determined that charging is already underway, S705 is executed.

[0187] If it is determined that the battery is not charged, S707 is executed.

[0188] For example, when it is determined that the minimum power is less than the remaining power of the wearable device 100, the wearable device 100 may display Fig. 8A The prompt information 801 shown includes a text message "Battery is too low, do you want to charge?", and the prompt information 801 is used to prompt the user to charge the wearable device 100 in time. The prompt information 801 also includes a confirmation option and a cancel option. Among them, the user can confirm to charge the wearable device 100 through the confirmation option, and the user can also confirm not to charge the wearable device 100 through the cancel option.

[0189] S707: The wearable device 100 prompts the user to change the blood pressure measurement plan, and determines whether the user agrees to change the blood pressure measurement plan.

[0190] When it is determined that the battery is not charged, the wearable device 100 can prompt the user to change the blood pressure measurement scheme, and determine whether the user agrees to change the blood pressure measurement scheme.

[0191] Among them, adjusting the blood pressure measurement scheme may refer to reducing the total number of blood pressure measurements in the blood pressure measurement scheme to save power consumption of the wearable device 100 so that the remaining power of the wearable device 100 can complete blood pressure measurements within a day.

[0192] In one possible implementation, the wearable device 100 can automatically reduce the total number of blood pressure measurements in the blood pressure measurement scheme based on the remaining power of the wearable device 100, so that the remaining power of the wearable device 100 can complete the total number of blood pressure measurements in the modified blood pressure measurement scheme.

[0193] In other possible implementations, the wearable device 100 may receive a user operation to reduce the total number of blood pressure measurements in the blood pressure measurement scheme, so that the remaining power of the wearable device 100 can complete the total number of blood pressure measurements in the modified blood pressure measurement scheme.

[0194] In some embodiments, after the wearable device 100 displays the prompt information 801, the wearable device 100 can determine whether the wearable device 100 is charging. If it is detected that the wearable device 100 is not charging within the first time period (for example, one minute), the wearable device 100 can display Figure 8B The prompt information 802 shown includes a text message "The current battery is too low, do you accept the adjustment of the blood pressure measurement plan?" The prompt information 802 is used to prompt the user to accept the adjustment of the blood pressure measurement plan to reduce the number of blood pressure measurements. The prompt information 802 also includes a yes option and a no option. The user can confirm to accept the adjustment of the blood pressure measurement plan through the yes option, and the user can also refuse to accept the adjustment of the blood pressure measurement plan through the no option.

[0195] If the user agrees to change the blood pressure measurement plan, execute S708.

[0196] If the user does not agree to change the blood pressure measurement plan, S709 is executed.

[0197] S708: The wearable device 100 saves the modified blood pressure measurement scheme.

[0198] If the user agrees to change the blood pressure measurement scheme, the wearable device 100 can save the modified blood pressure measurement scheme.

[0199] S709: The wearable device 100 prompts the user to enter the low power consumption mode, and determines whether the user agrees to enter the low power consumption mode.

[0200] If the user does not agree to change the blood pressure measurement scheme, the wearable device 100 can prompt the user to enter the low power mode to save power consumption and electricity of the wearable device 100. The wearable device 100 needs to determine whether the user agrees to enter the low power mode.

[0201] Among them, controlling the wearable device 100 to enter the low power consumption mode may refer to shutting down some or all energy-consuming operations on the wearable device 100 that are not related to blood pressure monitoring. For example, energy-consuming operations may include but are not limited to heart rate monitoring functions, sports data recording functions, etc.

[0202] If the user agrees that the wearable device 100 enters the low power consumption mode, S705 is executed.

[0203] In a case where the user does not agree that the wearable device 100 enters the low power consumption mode, S710 is executed.

[0204] For example, Figure 8B As shown, the wearable device 100 can receive a user input operation (eg, a single click) for a no option in the prompt information 802. In response to the user's input operation, the wearable device 100 does not adjust the blood pressure measurement scheme.

[0205] After the user chooses not to adjust the blood pressure measurement scheme, the wearable device 100 may display Figure 8C The prompt information 803 shown includes prompt information 803, which includes text information "The current power is too low, do you want to enter low power mode?" The prompt information 803 is used to prompt the user to control the wearable device 100 to enter the low power mode to save the power consumption of the wearable device 100 and save power. The prompt information 803 also includes a yes option and a no option. Among them, the user can control the wearable device 100 to enter the low power mode through the yes option, and the user can also not control the wearable device 100 to enter the low power mode through the no option.

[0206] S710: The wearable device 100 prompts the user that the battery is too low and may shut down at any time.

[0207] If the user does not agree that the wearable device 100 enters the low power consumption mode, the wearable device 100 may prompt the user that the battery is too low and may shut down at any time.

[0208] For example, Figure 8C As shown, the wearable device 100 can receive an input operation (such as a click) from the user for the No option in the prompt information 803. In response to the input operation from the user, the wearable device 100 does not enter the low power consumption mode.

[0209] In response to the user's input operation for the no option in the prompt information 803, the wearable device 100 may display Fig.8D The prompt information 804 shown may include a text message "The battery is too low and may shut down at any time. Please charge in time!" to remind the user that the battery of the wearable device 100 is too low.

[0210] Optional, Figure 7 In an embodiment, before starting to measure blood pressure within a day, it can be determined whether the power of the wearable device 100 is too low, so as to select a suitable strategy to save the power consumption of the wearable device 100 and increase the usage time of the remaining power of the wearable device 100.

[0211] The wearable device 100 uses a blood pressure measurement scheme and displays a single blood pressure measurement result.

[0212] After obtaining the blood pressure measurement scheme, the wearable device 100 can monitor the user's blood pressure within a day based on the blood pressure measurement scheme.

[0213] Based on the foregoing description, it can be seen that the blood pressure measurement scheme may include one or more blood pressure measurement strategies, which may include but are not limited to: the start time of the blood pressure measurement, the end time of the blood pressure measurement, the duration of the blood pressure measurement, the number of blood pressure measurements within the duration of the blood pressure measurement, the time interval between two adjacent blood pressure measurements within the duration of the blood pressure measurement, the total number of blood pressure measurements, etc.

[0214] In some embodiments, before the wearable device 100 uses the blood pressure measurement solution to measure blood pressure, it is necessary to determine whether the current user state meets the blood pressure measurement conditions. If the blood pressure measurement conditions are met, the wearable device 100 starts to measure the user's blood pressure. If the blood pressure measurement conditions are not met, the wearable device 100 does not measure the user's blood pressure until the blood pressure measurement conditions are met and then starts to measure the user's blood pressure.

[0215] Fig. 9 A schematic flow chart of a method for measuring a user's blood pressure by a wearable device 100 is shown.

[0216] S901. The wearable device 100 obtains the current user status.

[0217] The current user status may include but is not limited to one or more of the following: motion data, physiological data, etc.

[0218] The motion data can be acceleration data, angular velocity data, cumulative step count, etc.

[0219] The physiological data may be a real-time heart rate and a nighttime static heart rate, etc. The nighttime static heart rate may be an average value of the heart rates measured by the wearable device 100 at night.

[0220] S902: The wearable device 100 determines whether the current user status meets the blood pressure measurement condition.

[0221] The blood pressure measurement conditions may include but are not limited to one or more of the following: the user is in a stationary state, and the difference between the real-time heart rate and the nighttime static heart rate is within a preset range.

[0222] The wearable device 100 may collect motion data based on a motion sensor. The motion sensor may include, but is not limited to, an acceleration sensor, a gyroscope sensor, etc. The motion sensor may collect motion data or a motion trajectory. The wearable device 100 may determine whether the user is in a stationary state based on the motion data or the motion trajectory.

[0223] Generally, the user is in a stationary state, the user has almost no activity, and the real-time heart rate is relatively stable. If the difference between the real-time heart rate and the nighttime static heart rate is within a preset range, it can be determined that the user is in a stationary state. The wearable device 100 can determine whether the user is in a stationary state based on the real-time heart rate collected by the PPG sensor.

[0224] When it is determined that the current user status satisfies the blood pressure measurement condition, S903 is executed.

[0225] When it is determined that the current user status does not meet the blood pressure measurement condition, S901 is executed.

[0226] In this way, before measuring blood pressure, the wearable device 100 can determine whether the blood pressure measurement conditions are met. When the blood pressure measurement conditions are met, the wearable device 100 starts to measure the user's blood pressure, which can improve the accuracy of blood pressure measurement. Because when the blood pressure measurement conditions are not met, the user may be in a non-stationary state, such as running or exercising, and the blood pressure result of the wearable device 100 may have errors.

[0227] S903: The wearable device 100 determines whether the time difference between the last blood pressure measurement time and the current time satisfies a preset time interval.

[0228] When it is determined that the current user status meets the blood pressure measurement condition, before starting to measure the blood pressure, the wearable device 100 can determine whether the time difference between the last blood pressure measurement time and the current time meets the preset time interval.

[0229] When it is determined that the time difference between the last blood pressure measurement time and the current time satisfies the preset time interval, S904 is executed.

[0230] If it is determined that the time difference between the last blood pressure measurement time and the current time does not satisfy the preset time interval, S901 is executed.

[0231] Based on the foregoing description, it can be known that the blood pressure measurement scheme determined by the wearable device 100 may include one or more blood pressure measurement strategies, which may include but are not limited to: the start time of the blood pressure measurement, the end time of the blood pressure measurement, the duration of the blood pressure measurement, the number of blood pressure measurements within the duration of the blood pressure measurement, the time interval between two adjacent blood pressure measurements within the duration of the blood pressure measurement, the total number of blood pressure measurements, etc.

[0232] Before starting to measure blood pressure, the wearable device 100 needs to determine whether the time difference between the last blood pressure measurement time and the current time is a preset time interval specified in the blood pressure measurement scheme.

[0233] The preset time intervals in different blood pressure measurement duration periods are different. For example, between 9 am and 12 pm, the preset time interval may be 20 minutes. Between 9 pm and 9 am, the preset time interval may be 30 minutes.

[0234] Before starting to measure blood pressure, the wearable device 100 can determine whether the time difference between the last blood pressure measurement time and the current time satisfies a preset time interval. If the preset time interval is met, the wearable device 100 starts measuring the user's blood pressure again to avoid frequent blood pressure measurements.

[0235] S904: The wearable device 100 measures the user's blood pressure and saves the blood pressure measurement result.

[0236] When it is determined that the time difference between the last blood pressure measurement time and the current time satisfies the preset time interval, the wearable device 100 can start measuring the user's blood pressure and save the blood pressure measurement result.

[0237] In some embodiments, in order to ensure the accuracy of blood pressure measurement, the wearable device 100 can display prompt information to prompt the user to measure blood pressure.

[0238] Figures 10A-10E A schematic diagram showing the wearable device 100 displaying prompt information to prompt the user to measure blood pressure.

[0239] For example, Fig. 10A As shown, when the wearable device 100 starts to measure blood pressure, in order to ensure the accuracy of the blood pressure measurement result, the wearable device 100 can display Fig. 10A User interface 710 is shown. User interface 710 shows a prompt message "It's time to measure blood pressure. Please stay still and click to start measuring". This prompt message is used to remind the user to stay still during the blood pressure measurement process to avoid inaccurate blood pressure measurement results caused by movement. User interface 710 also includes a measurement reminder option and a skip option. The user can view the precautions for measuring blood pressure through the measurement reminder option, and the user can also skip the precautions for measuring blood pressure and start measuring blood pressure directly.

[0240] For example, Fig. 10A As shown, the wearable device 100 can receive a user input operation (such as a single click) for the measurement reminder option in the user interface 710, and in response to the user input operation, the wearable device 100 can display Fig. 10BThe user interface 720 shown. The user interface 720 includes a prompt message "Please note that the watch should be worn flush with the heart during measurement, and do not press the heart", which is used to remind the user of the correct measurement posture. The user interface 720 includes a timing option 7201, which is used to remind the user to lift the watch to a position flush with the heart within a preset time.

[0241] After the countdown time displayed by the wearable device 100 reaches 0, the wearable device 100 can start measuring the user's blood pressure.

[0242] Optionally, during the process of the wearable device 100 measuring the user's blood pressure, the wearable device 100 may display Fig. 10C The user interface 730 shown includes a prompt message "Please remain still during blood pressure measurement" to prompt the user to remain still during the blood pressure measurement to avoid inaccurate blood pressure measurement results due to movement. The user interface 730 also includes a cancel measurement option, and the user can stop the blood pressure measurement by canceling the measurement option.

[0243] In some embodiments, after the wearable device 100 obtains a blood pressure monitoring value, the wearable device 100 may display Fig. 10D The user interface 740 shown includes a blood pressure measurement value, which may include high pressure and low pressure. For example, the high pressure may be 130 mmHg, and the low pressure may be 80 mmHg. In some embodiments, the user interface 740 may also include a pulse, for example, the pulse may be 69 beats per minute.

[0244] In some embodiments, after the wearable device 100 obtains a blood pressure monitoring value, the wearable device 100 may also display Fig.10E The user interface 750 shown in the figure shows detailed information of the blood pressure measurement, such as the user status, the total number of blood pressure measurements, the time interval from the last blood pressure measurement, the time interval from the next blood pressure measurement, etc. For example, Fig.10E The user status shown in the figure is a static state, the total number of blood pressure measurements is 5 times, the interval from the last blood pressure measurement is 20 minutes, and the estimated time for starting the next blood pressure measurement is also 20 minutes.

[0245] The user interface 750 also includes a confirmation option and an optimization blood pressure measurement scheme option. Among them, the user can use the confirmation option to make the wearable device 100 stop displaying the user interface 750, and the user can also actively modify the blood pressure measurement scheme through the optimization blood pressure measurement scheme option. For details, please refer to the description in the following embodiments, and this application will not repeat them here.

[0246] In some embodiments, the wearable device 100 may not display Figures 10A-10E The wearable device 100 may not display the prompt information shown in the figure, and directly start measuring the user's blood pressure. Avoid frequently disturbing the user. For example, at night, the wearable device 100 may not display the prompt information shown in the figure. Figures 10A-10E The wearable device 100 may not display the prompt information and automatically measure the user's blood pressure to avoid disturbing the user's rest.

[0247] In some embodiments, the wearable device 100 can measure the user's blood pressure and obtain the blood pressure measurement result. Before saving the blood pressure measurement result, the wearable device 100 needs to determine whether the current user state meets the blood pressure measurement condition. If the blood pressure measurement condition is met, the wearable device 100 can directly save the blood pressure measurement result. If the blood pressure measurement condition is not met, the wearable device 100 can determine the blood pressure compensation value based on the current user state, and revise the blood pressure measurement result based on the blood pressure compensation value, and save the revised blood pressure measurement result.

[0248] Fig.11 A flow chart of another method for measuring a user's blood pressure using a wearable device 100 is shown.

[0249] S1101: The wearable device 100 determines whether the time difference between the last blood pressure measurement time and the current time satisfies a preset time interval.

[0250] Before starting to measure blood pressure, the wearable device 100 needs to determine whether the time difference between the last blood pressure measurement time and the current time satisfies a preset time interval.

[0251] When it is determined that the time difference between the last blood pressure measurement time and the current time satisfies the preset time interval, S1102 is executed.

[0252] If it is determined that the time difference between the last blood pressure measurement time and the current time does not meet the preset time interval, the process ends without measuring the blood pressure until the time difference between the last blood pressure measurement time and the current time meets the preset time interval.

[0253] Based on the foregoing description, it can be known that the blood pressure measurement scheme determined by the wearable device 100 may include one or more blood pressure measurement strategies, which may include but are not limited to: the start time of the blood pressure measurement, the end time of the blood pressure measurement, the duration of the blood pressure measurement, the number of blood pressure measurements within the duration of the blood pressure measurement, the time interval between two adjacent blood pressure measurements within the duration of the blood pressure measurement, the total number of blood pressure measurements, etc.

[0254] Before starting to measure blood pressure, the wearable device 100 needs to determine whether the time difference between the last blood pressure measurement time and the current time is a preset time interval specified in the blood pressure measurement scheme.

[0255] The preset time intervals in different blood pressure measurement duration periods are different. For example, between 9 am and 12 pm, the preset time interval may be 20 minutes. Between 9 pm and 9 am, the preset time interval may be 30 minutes.

[0256] Before starting to measure blood pressure, the wearable device 100 can determine whether the time difference between the last blood pressure measurement time and the current time satisfies a preset time interval. If the preset time interval is met, the wearable device 100 starts measuring the user's blood pressure again to avoid frequent blood pressure measurements.

[0257] S1102: The wearable device 100 measures blood pressure and obtains a blood pressure measurement result.

[0258] When it is determined that the time difference between the last blood pressure measurement time and the current time satisfies the preset time interval, the wearable device 100 can start measuring the blood pressure and obtain the blood pressure measurement result.

[0259] S1103: The wearable device 100 obtains the current user status.

[0260] S1104: The wearable device 100 determines whether the current user status satisfies the blood pressure measurement condition.

[0261] The wearable device 100 obtains the current user state and determines whether the current user state meets the blood pressure measurement condition.

[0262] For the introduction of S1103-S1104, please refer to the description in S901-S902, and this application will not go into details here.

[0263] When it is determined that the current user status satisfies the blood pressure measurement condition, S1105 is executed.

[0264] If it is determined that the current user status does not meet the blood pressure measurement condition, S1106 is executed.

[0265] S1105. The wearable device 100 saves the blood pressure measurement result.

[0266] When it is determined that the current user status meets the blood pressure measurement conditions, the wearable device 100 can directly save the blood pressure measurement result.

[0267] S1106. The wearable device 100 obtains a blood pressure compensation value based on the current user state.

[0268] When it is determined that the current user state does not meet the blood pressure measurement condition, the wearable device 100 can obtain a blood pressure compensation value based on the current user state. Different user states determine different blood pressure compensation values.

[0269] S1107: The wearable device 100 obtains a corrected blood pressure measurement value based on the blood pressure compensation value and the blood pressure measurement value.

[0270] S1108. The wearable device 100 saves the corrected blood pressure measurement value.

[0271] After determining whether the current user state meets the blood pressure measurement conditions, the wearable device 100 can obtain a blood pressure compensation value based on the current user state, and correct the blood pressure measurement value based on the blood pressure compensation value to obtain a corrected blood pressure measurement value, so as to eliminate the influence of the user state that does not meet the blood pressure measurement conditions on the blood pressure measurement value.

[0272] After obtaining the corrected blood pressure measurement value, the wearable device 100 can save the corrected blood pressure measurement value.

[0273] Depend on Figure 7 It can be seen from the embodiment that after the wearable device 100 determines the blood pressure measurement scheme, before the wearable device 100 uses the blood pressure measurement scheme, the wearable device 100 can determine the minimum power required for the blood pressure measurement scheme. When the remaining power of the wearable device 100 is too low, the user can charge the wearable device 100 in time to avoid the situation where the wearable device 100 is shut down and cannot measure blood pressure due to low power.

[0274] In some embodiments, before measuring blood pressure, the wearable device 100 needs to detect whether it is in a wearing state. If it is not in a wearing state, the user is promptly prompted to wear the wearable device 100 and start measuring blood pressure.

[0275] Fig.12 A flowchart of another method for measuring a user's blood pressure using a wearable device 100 is shown.

[0276] S1201: The wearable device 100 recognizes that it is not being worn.

[0277] S1202: The wearable device 100 determines whether the remaining power of the wearable device 100 meets the minimum power required by the blood pressure measurement solution.

[0278] The wearable device 100 can determine whether the wearable device 100 is worn on the user's wrist. If the wearable device 100 is not worn on the user's wrist, the wearable device 100 determines that it is in a non-worn state.

[0279] The wearable device 100 can obtain the remaining power of the wearable device 100 and determine the minimum power required to complete the blood pressure measurement scheme based on the blood pressure measurement scheme.

[0280] The wearable device 100 needs to determine whether the remaining power of the wearable device 100 is greater than the minimum power required by the blood pressure measurement solution.

[0281] When the remaining power of the wearable device 100 is less than the minimum power required by the blood pressure measurement scheme, S1203 is executed.

[0282] When the remaining power of the wearable device 100 is greater than the minimum power required by the blood pressure measurement scheme, S1204 is executed.

[0283] S1203: The wearable device 100 sends message 1 to the electronic device 200, where the message 1 is used to instruct the electronic device 200 to remind the user to charge the wearable device 100 in time.

[0284] When the remaining power of the wearable device 100 is less than the minimum power required by the blood pressure measurement scheme, in order to avoid the wearable device 100 being shut down and unable to measure blood pressure due to low power, the wearable device 100 can send message 1 to the electronic device 200 that has established a communication connection with it. Message 1 is used to instruct the electronic device 200 to remind the user to charge the wearable device 100 in time.

[0285] After receiving the message 1 sent by the wearable device 100, the electronic device 200 can prompt the user to charge the wearable device 100 in time.

[0286] Optionally, the prompt method may include but is not limited to: vibration, voice, pop-up window, flashing light, etc.

[0287] Optionally, the electronic device 200 may adopt different prompting methods based on different usage states.

[0288] For example, when the electronic device 200 is in use, the electronic device 200 can prompt the user to charge the wearable device 100 in time through a pop-up window.

[0289] For example, Fig.13A As shown, the electronic device 200 can display a prompt bar 1301 above the main interface, and the prompt bar 1301 includes a prompt message "Battery is too low, please charge the wearable device 100 in time." The prompt bar 1301 is used to prompt the user to charge the wearable device 100 in time.

[0290] For example, Fig. 13B As shown, the electronic device 200 can display a prompt message 1302 in the pull-down notification bar, and the prompt message 1302 includes a prompt message "Battery is too low, please charge the wearable device 100 in time." The prompt message 1302 is used to prompt the user to charge the wearable device 100 in time.

[0291] Not limited to Fig.13A , Fig. 13BThe electronic device 200 shown displays prompt information to prompt the user to charge the wearable device 100 in time. The electronic device 200 can also prompt the user to charge the wearable device 100 in time in other ways, which will not be repeated in the embodiments of the present application.

[0292] For another example, when the electronic device 200 is not in use, the electronic device 200 can remind the user to charge the wearable device 100 in time through one or more methods such as vibration, voice, flashing lights, etc.

[0293] S1204: The wearable device 100 determines whether the current user status satisfies the blood pressure measurement condition.

[0294] When the remaining power of the wearable device 100 is greater than the minimum power required by the blood pressure measurement solution, the wearable device 100 needs to determine whether the current user state meets the blood pressure measurement conditions. If the current user state meets the blood pressure measurement conditions, the wearable device 100 starts measuring the user's blood pressure.

[0295] For the introduction of S1204, please refer to the description in S901-S902, and this application will not go into details here.

[0296] When it is determined that the current user status satisfies the blood pressure measurement condition, S1205 is executed.

[0297] When it is determined that the current user state does not meet the blood pressure measurement condition, the user state is continuously monitored until the user state meets the blood pressure measurement condition.

[0298] S1205: The wearable device 100 determines whether it is time to measure the blood pressure after the first preset time.

[0299] When it is determined that the current user state meets the blood pressure measurement condition, before measuring the blood pressure, the wearable device 100 can determine whether the blood pressure measurement time has arrived after the first preset time, so that the electronic device 200 can remind the user to wear the wearable device 100 in advance and in time to measure the blood pressure.

[0300] When it is determined that the blood pressure measurement time has arrived after the first preset time, S1206 is executed so that the electronic device 200 can remind the user to wear the wearable device 100 in advance and in time to measure the blood pressure.

[0301] If it is determined that the blood pressure measurement time has not arrived after the first preset time, S1204 is executed.

[0302] S1206. The wearable device 100 sends a second message to the electronic device 200. The second message is used to instruct the electronic device 200 to remind the user to wear the wearable device 100 in time.

[0303] When the wearable device 100 determines that the blood pressure measurement time has not arrived after the first preset time, in order to enable the electronic device 200 to remind the user to wear the wearable device 100 in advance and in time, the wearable device 100 can send message 2 to the electronic device 200 with which a communication connection is established, and message 2 is used to instruct the electronic device 200 to remind the user to wear the wearable device 100 in time.

[0304] After receiving the second message sent by the wearable device 100 , the electronic device 200 may prompt the user to wear the wearable device 100 in time.

[0305] Optionally, the prompt method may include but is not limited to: vibration, voice, pop-up window, flashing light, etc.

[0306] Optionally, the electronic device 200 may adopt different prompting methods based on different usage states.

[0307] For example, when the electronic device 200 is in use, the electronic device 200 can prompt the user to wear the wearable device 100 in time through a pop-up window.

[0308] For example, Fig. 13C As shown, the electronic device 200 can display a prompt bar 1303 above the main interface, and the prompt bar 1303 includes a prompt message "Blood pressure will be measured soon, please wear the wearable device 100 in time." The prompt bar 1301 is used to prompt the user to wear the wearable device 100 in time.

[0309] For example, Fig.13D As shown, the electronic device 200 can display a prompt message 1304 in the pull-down notification bar, and the prompt message 1304 includes a prompt message "Blood pressure will be measured soon, please wear the wearable device 100 in time." The prompt message 1304 is used to prompt the user to wear the wearable device 100 in time.

[0310] Not limited to Fig. 13C , Fig.13D The electronic device 200 shown displays prompt information to prompt the user to wear the wearable device 100 in time. The electronic device 200 can also prompt the user to wear the wearable device 100 in time in other ways, which will not be repeated in the embodiments of the present application.

[0311] For another example, when the electronic device 200 is not in use, the electronic device 200 can prompt the user to wear the wearable device 100 in time through one or more methods such as vibration, voice, flashing lights, etc.

[0312] After the wearable device 100 completes a cycle of blood pressure measurement using the blood pressure measurement solution, it displays the blood pressure measurement result within the cycle.

[0313] Exemplarily, 24 hours may be one cycle.

[0314] Figures 14A-14D A schematic diagram showing a wearable device 100 or an electronic device 200 displaying blood pressure measurement results within a cycle.

[0315] For example, after the wearable device 100 completes a cycle of blood pressure measurement, the wearable device 100 may display Fig.14A User interface 1410 is shown. User interface 1410 includes blood pressure measurement results within a cycle. For example, the average high pressure within 24 hours is 125 mmHg, and the average low pressure within 24 hours is 70 mmHg. The average high pressure during the day is 130 mmHg, and the average low pressure during the day is 75 mmHg. The average high pressure at night is 110 mmHg, and the average low pressure at night is 65 mmHg. User interface 1410 also shows a prompt message "Please see the mobile phone for detailed report", and the user can view the detailed information of the blood pressure measurement results within a cycle on the electronic device 200.

[0316] For example, Fig. 14B FIG. 14 shows a user interface 1420 showing details of a blood pressure measurement cycle on the electronic device 200. Fig. 14B As shown, user interface 1420 includes sleeping time, waking time and dynamic blood pressure trend graph within a cycle. Among them, the sleeping time can be 8:30 pm on October 11, 2023. The waking time can be 8:30 am on October 12, 2023. The dynamic blood pressure trend graph can show the trend of blood pressure changes within a cycle. User interface 1420 also includes 50 blood pressure measurements, an average high pressure of 125 mmHg in a cycle (e.g., 24h), and an average low pressure of 70 mmHg. The average high pressure during the day in a cycle (e.g., 24h) is 130 mmHg, and the average low pressure during the day is 75 mmHg. The average high pressure at night in a cycle (e.g., 24h) is 110 mmHg, and the average low pressure at night is 65 mmHg. The law of circadian blood pressure changes in a cycle (e.g., 24h) is a dipper-shaped rhythm. Based on the blood pressure measurement results within a cycle, the user interface 1400 also displays interpretations and suggestions: your blood pressure level is within the normal range and your circadian rhythm is normal. Please continue to pay attention to your blood pressure level.

[0317] In other embodiments, when the wearable device 100 has not completed the blood pressure measurement within a cycle, for example, it has only completed multiple blood pressure measurements within a time period, the user can also view the blood pressure detection results within this time period on the wearable device 100 or the electronic device 200.

[0318] For example, Fig. 14C As shown, a user interface 1430 is displayed on the wearable device 100, and the user interface 1430 displays the average blood pressure measurement within this time period, for example, the average high pressure within this time period is 125 mmHg, and the average low pressure is 70 mmHg. The user interface 1430 also displays a prompt message "Please see the mobile phone for detailed report", and the user can view the detailed information of the blood pressure measurement result within this time period on the electronic device 200.

[0319] For example, Fig.14D FIG. 14 shows a user interface 1440 on the electronic device 200 showing details of blood pressure measurements within a time period. Fig.14D As shown, user interface 1440 includes the start time and end time of blood pressure measurement and a dynamic blood pressure trend graph within this time period. Among them, the start time of blood pressure measurement can be 6:30 in the morning of October 11, 2023. The end time of blood pressure measurement can be 9:30 in the morning of October 11, 2023. The dynamic blood pressure trend graph can show the trend of blood pressure changes within a time period. User interface 1440 also includes 10 blood pressure measurements, and the average high pressure in this time period is 125mmHg, and the average low pressure is 70mmHg. Based on the blood pressure measurement results within this time period, interpretation and suggestions are also shown in user interface 1440: During the measurement time period, your average blood pressure is 125 / 70mmHg, which is at a normal level. If you need a complete evaluation, please complete the 24h full measurement.

[0320] The wearable device 100 corrects the blood pressure measurement scheme based on the historical blood pressure measurement data to obtain an optimized blood pressure measurement scheme.

[0321] In some embodiments, the wearable device 100 can obtain historical blood pressure measurement data within a first period of time (for example, one month), and modify the blood pressure measurement scheme obtained by the wearable device 100 based on the historical blood pressure measurement data within the first period of time.

[0322] 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 of the historical blood pressure measurement, the end time of the historical blood pressure measurement, the duration of the historical blood pressure measurement, the number of blood pressure measurements within the duration of the historical blood pressure measurement, the time interval between two adjacent blood pressure measurements within the duration of the historical blood pressure measurement, the total number of historical blood pressure measurements, etc.

[0323] In a possible implementation, the wearable device 100 may periodically / irregularly modify the blood pressure measurement scheme based on historical blood pressure measurement data to obtain an optimized blood pressure measurement scheme, so that the optimized blood pressure measurement scheme is more consistent with the user's behavioral characteristics.

[0324] In other possible implementations, the wearable device 100 may also receive a user operation to modify the blood pressure measurement scheme based on historical blood pressure measurement data to obtain an optimized blood pressure measurement scheme, so that the optimized blood pressure measurement scheme is more in line with the user's behavioral characteristics.

[0325] For example, when the wearable device 100 determines that the user is a hypertensive user based on historical blood pressure measurement data, the total number of blood pressure measurements in the optimized blood pressure measurement scheme determined by the wearable device 100 can be increased to monitor the user's blood pressure in more detail.

[0326] For another example, when the wearable device 100 determines that the user has normal blood pressure based on historical blood pressure measurement data, the total number of blood pressure measurements in the optimized blood pressure measurement scheme determined by the wearable device 100 can be reduced to reduce the power consumption of the wearable device 100.

[0327] For another example, when the wearable device 100 determines based on historical blood pressure measurement data that the user's blood pressure is high between 9 a.m. and 11 a.m., the total number of blood pressure measurements between 9 a.m. and 11 a.m. in the optimized blood pressure measurement plan determined by the wearable device 100 can be increased to perform more detailed monitoring of the user's blood pressure between 9 a.m. and 11 a.m.

[0328] Fig.15 A method flow chart of a method for generating a blood pressure measurement scheme provided in this application.

[0329] S1501: The wearable device obtains one or more of user information, physiological data, and device status.

[0330] S1502. The wearable device generates a blood pressure measurement plan based on one or more of the user information, physiological data and device status. The blood pressure measurement plan includes one or more of the following: the start time of the blood pressure measurement, the end time of the blood pressure measurement, the duration of the blood pressure measurement, the number of blood pressure measurements within the duration of the blood pressure measurement, the time interval between two adjacent blood pressure measurements within the duration of the blood pressure measurement, and the total number of blood pressure measurements.

[0331] S1503: The wearable device obtains a blood pressure measurement value of the user within a blood pressure measurement cycle based on the blood pressure measurement scheme.

[0332] For example, a blood pressure measurement cycle may be a 24-hour cycle.

[0333] Through this method, the wearable device can automatically generate a blood pressure measurement plan based on the fusion of multiple information, so that the blood pressure measurement plan generated by the wearable device is more in line with the user's characteristics, which not only saves user operations but also improves the rationality of blood pressure measurement.

[0334] In one possible implementation, user information includes one or more of the following: gender, age, height, weight, smoking history, drinking history, medical history, medication history, and living habits; physiological data includes one or more of the following: heart rate, blood pressure, arteriosclerosis, and blood sugar; device status includes one or more of the following: remaining power and device temperature.

[0335] In one possible implementation, the wearable device generates a blood pressure measurement plan based on one or more of user information, physiological data and device status, specifically including: the wearable device determines the risk level of the user's hypertension risk based on one or more of user information, physiological data and device status; the wearable device generates a blood pressure measurement plan based on the user's risk level of hypertension risk.

[0336] Different blood pressure measurement schemes are generated for different risk levels of hypertension risk. For example, the total number of blood pressure measurements determined by the wearable device based on high risk is greater than the total number of blood pressure measurements determined by the wearable device based on low risk.

[0337] In some embodiments, the risk level of hypertension risk may refer to the risk level in a certain time period within a blood pressure measurement cycle. For example, the risk level of hypertension risk of a user in the night time period is greater than the risk level of hypertension risk of the user in the day time period. Then the total number of blood pressure measurements in the night time period is greater than the total number of blood pressure measurements in the day time period.

[0338] In this way, the wearable device can determine the risk level of the user's hypertension risk based on a variety of information, and then generate a blood pressure measurement plan based on the risk level of hypertension risk.

[0339] In one possible implementation, after the wearable device generates a blood pressure measurement plan, the method also includes: the wearable device displays a first prompt message, and the first prompt message is used to prompt the user to view the details of the blood pressure measurement plan; the wearable device receives and responds to the user's first operation on the first option in the first prompt message, and displays a first user interface, in which the details of the blood pressure measurement plan are displayed.

[0340] In this way, after the wearable device automatically generates a blood pressure measurement plan, the wearable device can prompt the user to view the details of the blood pressure measurement plan. In some embodiments, the wearable device can also receive user operations to modify the blood pressure measurement plan.

[0341] In a possible implementation, before the wearable device measures and obtains the blood pressure measurement value of the user within a blood pressure measurement cycle based on the blood pressure measurement scheme, the method also includes: the wearable device obtains the remaining power of the wearable device; when the remaining power of the wearable device is less than a preset power, the wearable device displays a second prompt message, and the second prompt message is used to prompt the user to charge the wearable device, wherein the preset power is the minimum power required for the wearable device to complete the blood pressure measurement within a blood pressure measurement cycle based on the blood pressure measurement scheme; when the wearable device is in a charging state within a first period of time after the second prompt message is displayed, the blood pressure measurement scheme is saved.

[0342] In this way, before the wearable device measures blood pressure based on the automatically generated blood pressure measurement plan, the device needs to determine whether the remaining power of the wearable device is sufficient. This prevents the wearable device from shutting down before completing a blood pressure measurement cycle. After the wearable device displays a prompt message and is in a charging state, the wearable device can save the blood pressure measurement plan and complete the blood pressure measurement within a blood pressure measurement cycle based on the blood pressure measurement plan.

[0343] In one possible implementation, the method also includes: when the wearable device is not in a charging state within a first period of time after displaying the second prompt information, the wearable device displays a third prompt information, and the third prompt information is used to prompt the user to change the blood pressure measurement plan; the wearable device receives and responds to the user's second operation on the second option in the third prompt information, obtains and saves a first updated blood pressure measurement plan, and the total number of blood pressure measurements in the first updated blood pressure measurement plan is less than the total number of blood pressure measurements in the blood pressure measurement plan; the wearable device obtains the user's blood pressure measurement value in a blood pressure measurement cycle based on the first updated blood pressure measurement plan.

[0344] Optionally, the power required by the first updated blood pressure measurement scheme to complete blood pressure measurement within a blood pressure measurement cycle is less than or equal to the remaining power of the wearable device.

[0345] In this way, when the wearable device is still not in the charging state after the wearable device displays the prompt information, the wearable device can prompt the user again to modify the blood pressure measurement plan and obtain the first updated blood pressure measurement plan.

[0346] In one possible implementation, the method also includes: the wearable device receives and responds to the user's third operation on the third option in the third prompt information, displays a fourth prompt information, and the fourth prompt information is used to prompt the user to set the wearable device to a low power consumption mode; the wearable device receives and responds to the user's fourth operation on the fourth option in the fourth prompt information, and enters a low power consumption mode.

[0347] Optionally, the low power consumption mode may refer to shutting down some or all energy-consuming operations on the wearable device 100 that are not related to blood pressure monitoring. For example, energy-consuming operations may include but are not limited to heart rate monitoring functions, exercise data recording functions, etc.

[0348] In this way, if the user still does not modify the blood pressure measurement plan after the wearable device displays the prompt information, the wearable device can prompt the user again to control the wearable device to enter the low power consumption mode in order to save the power of the device.

[0349] In a possible implementation, the method further includes: the wearable device receives and responds to a fifth operation of the user on a fifth option in the fourth prompt information, and displays a fifth prompt information, where the fifth prompt information is used to prompt the user that the battery of the wearable device is too low.

[0350] In this way, if the wearable device has not entered the low power consumption mode after the wearable device displays the prompt information, the wearable device can remind the user that the battery of the device is too low and may be shut down at any time.

[0351] In a possible implementation, the blood pressure measurement value includes a first blood pressure measurement value obtained by the wearable device at a first moment; after the wearable device obtains the first blood pressure measurement value, the method further includes: the wearable device obtains a current user state; when the current user state meets the blood pressure measurement condition, the wearable device saves the first blood pressure measurement value

[0352] In a possible implementation, the method also includes: when the current user state does not meet the blood pressure measurement conditions, the wearable device obtains a blood pressure compensation value based on the current user state; the wearable device obtains a first blood pressure monitoring value based on the blood pressure compensation value and the first blood pressure measurement value; and the wearable device saves the first blood pressure monitoring value.

[0353] The blood pressure measurement conditions may include but are not limited to one or more of the following: the user is in a stationary state, and the difference between the real-time heart rate and the nighttime static heart rate is within a preset range.

[0354] The wearable device can collect motion data based on a motion sensor. The motion sensor may include but is not limited to: an acceleration sensor, a gyroscope sensor, etc. The motion sensor can collect motion data or a motion trajectory. The wearable device can determine whether the user is in a stationary state based on the motion data or the motion trajectory.

[0355] In this way, when measuring blood pressure, the wearable device can determine whether the user's state meets the blood pressure measurement conditions. If the conditions are met, the blood pressure measurement results can be directly saved. If not, the wearable device needs to correct the blood pressure measurement results and then save the corrected blood pressure measurement results, which can improve the accuracy of blood pressure measurement.

[0356] In a possible implementation, the method also includes: the wearable device obtains historical blood pressure measurement data, wherein the historical blood pressure measurement data includes historical blood pressure measurement records and historical blood pressure measurement results; the wearable device updates the blood pressure measurement scheme based on the historical blood pressure measurement data, generates and saves a second updated blood pressure measurement scheme; the wearable device obtains the blood pressure measurement value of the user within a blood pressure measurement cycle based on the second updated blood pressure measurement scheme.

[0357] The historical blood pressure measurement records include but are 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 of the historical blood pressure measurement, the end time of the historical blood pressure measurement, the duration of the historical blood pressure measurement, the number of blood pressure measurements within the duration of the historical blood pressure measurement, the time interval between two adjacent blood pressure measurements within the duration of the historical blood pressure measurement, the total number of historical blood pressure measurements, etc.

[0358] In this way, the wearable device can periodically / irregularly update the blood pressure measurement solution based on the user's historical data to improve the accuracy of the blood pressure measurement solution generated by the wearable device.
