Abstract

[Problem] Blood pressure measurement method, electronic device, and medium. [Solution] Whether or not to measure blood pressure, and the specific blood pressure measurement mode to be used, is determined based on the degree of impact on the user's sleep status. The measurement modes are classified into a first measurement mode and a second measurement mode. In the first measurement mode, the user needs to be prompted to adjust their blood pressure measurement posture to meet the blood pressure measurement requirements. After the user confirms that their posture has been adjusted, blood pressure is measured for the user. In the second measurement mode, blood pressure can be measured for the user without prompting them to adjust their blood pressure measurement posture, and finally, the user's blood pressure measurement is compensated based on the error between the user's blood pressure measurement in that posture and the user's blood pressure measurement in the posture used for blood pressure measurement. In this way, the impact of blood pressure measurement pressurization on the user's sleep status can be reduced. [Selection Diagram] Figure 9

Description

This application claims priority to Chinese Patent Application No. 202111569275.3, titled "DYNAMIC BLOOD PRESSURE MONITORING DEVICE AND METHOD," filed with the China National Intellectual Property Administration on December 21, 2021, and Chinese Patent Application No. 202210383491.7, titled "BLOOD PRESSURE MEASUREMENT METHOD, ELECTRONIC DEVICE, AND MEDIUM," filed with the China National Intellectual Property Administration on April 12, 2022, both of which are incorporated herein by reference in their entirety. This application relates to the fields of physiological and health technologies, and more particularly to methods, electronic devices, and media for measuring blood pressure. Wearable devices, such as smartwatches, may have both the ability to monitor a user's sleep status and the ability to measure their blood pressure. When wearable devices, such as smartwatches (hereinafter referred to as "watches"), are used for dynamic blood pressure monitoring, there are typically two user postures: one is seated, and the other is reclining. The seated posture means the user sits in a chair with back support, both feet on the ground, and raises their arm so that the watch on their wrist is horizontal to their heart. Then, blood pressure is calculated based on the pulse wave using a conventional oscillometric method. The reclining posture means the user lies flat on a bed or on the side of a bed. In this case, there may be a difference in elevation between the watch on the wrist and the heart. A gyroscope must be used to determine the reclining posture, and then a corrected oscillometric method is used to compensate for deviations in blood pressure measurement caused by the elevation difference. The typical method for dynamic blood pressure monitoring involves the user setting the start time and duration of blood pressure measurements, and then measuring the user's blood pressure at regular intervals. However, when dynamic blood pressure monitoring is performed while the user is asleep, the wearable device may wake the user during the process of pressurizing the wrist, potentially disrupting their sleep. To solve the aforementioned problems, this application provides a blood pressure measurement method, an electronic device, and a medium. This will be explained in detail below. According to a first aspect, one embodiment of the present application provides a blood pressure measurement method applicable to a wearable device, the wearable device comprising a photoplethysmography PPG sensor, a micropump, and an airbag, wherein the method includes: determining the user's heart rate based on the PPG sensor; displaying a first user interface if the user's heart rate is greater than a first heart rate threshold, the first user interface being used to prompt the user to measure blood pressure; and controlling the micropump in response to a detected first action performed on the first user interface to measure the blood pressure. The process includes the steps of: performing a first measurement operation on the airbag, where the first measurement operation is used to measure the blood pressure; determining whether the current time is within a first time range if the user's heart rate is less than a second heart rate threshold, where the second heart rate threshold is less than or equal to the first heart rate threshold; and controlling the micropump to perform a second measurement operation on the airbag if the current time is within the first time range, where the second measurement operation is used to measure the blood pressure, wherein the same pressurization mode is used for the first and second measurement operations. The user's heart rate is used to determine the user's status. For example, if the user's heart rate is greater than a first heart rate threshold, the user is determined to be awake. In this case, corresponding prompt information may be displayed on the first user interface to encourage the user to adjust their posture to meet the blood pressure measurement requirements. After the user adjusts their posture, the user may confirm that the posture adjustment is complete by tapping the first action, and as a result, the wearable device can perform blood pressure measurement. Specifically, the blood pressure measurement process includes: the wearable device controlling a micropump to perform a first measurement action on an airbag, the first measurement action being used to control the micropump to inflate and deflate the airbag. This blood pressure measurement mode is also referred to as the first measurement mode. If the user's heart rate is below the second heart rate threshold, the user is determined to be asleep. If the current time is within the first time range, the user may not be prompted. The micropump is then controlled to perform a second measurement action on the airbag, which is used to control the micropump to inflate and deflate the airbag. This blood pressure measurement mode is also referr
