To reduce the burden on the subject when measuring blood pressure. [Solution] The biological information processing device 1 includes a blood pressure detection unit 13 that identifies a reference pulse wave from pulse waves measured in the past and detects a first reference blood pressure value, a second reference blood pressure value, and a third reference blood pressure value, based on the amplitude of the reference pulse wave; and a blood pressure estimation unit 14 that, when a part of the waveform including the rising edge of a newly measured pulse wave corresponds to a part of the waveform including the rising edge of the reference pulse wave, estimates at least one value or range of the first blood pressure value, second blood pressure value, and third blood pressure value based on the new pulse wave, based on the corresponding value among the first reference blood pressure value, second reference blood pressure value, and third reference blood pressure value.

This invention provides a signal anti-interference processing method and system for assisting smartwatches in measuring blood pressure, relating to the field of medical monitoring signal processing technology. First, it collects the initial pulse wave signal and motion state data of the target user. The current interference level is quantified by calculating a motion interference intensity coefficient. When this coefficient is within a preset range, a dynamically adapted multi-layer filtering fusion is performed based on the initial pulse wave signal and the interference intensity coefficient. Then, variational mode decomposition is performed on the fused filtered signal to remove respiratory fluctuation interference. Finally, the blood pressure measurement result is obtained from the pure target pulse wave signal. This solves the technical problem of insufficient blood pressure measurement accuracy caused by motion artifacts, respiratory fluctuations, and other multi-source interference leading to pulse wave signal distortion when smartwatches use the oscilloscope method to measure wrist blood pressure. It has the technical effect of accurately processing multi-source interference, improving the purity of the pulse wave signal, and reducing blood pressure measurement errors.

A wearable device (100) comprises a motion sensor (203G) and a PPG module. A blood pressure detection method applied to the wearable device comprises: the wearable device (100) acquires motion data collected by the motion sensor (203G) and a first PPG signal collected by the PPG module; in a case where the motion data and / or the first PPG signal satisfies a first condition, the wearable device (100) determines whether a user is in a sleep state; in a case where it is determined that the user is in a first sleep event, the wearable device (100) acquires a first blood pressure value; the first sleep event comprises any one or more of the following: an OSA event, an REM event, an NREM sleep event, and a central sympathetic nervous activity increase event. When a specific sleep event is detected, the blood pressure is measured again, and when the specific sleep event is not detected, the blood pressure is stopped from being measured, so that the interference with the user's sleep is reduced, the power consumption of the wearable device (100) is reduced, and the user experience is improved.
