Abstract

A blood pressure measurement system and method includes: detecting, by a physiological information measurer, a first wave signal from a blood vessel during a first application period of a wearable application unit that applies pressure to an upstream blood vessel of the blood vessel; generating a first packet signal of the first wave signal according to the first wave signal; detecting a second wave signal from the blood vessel by using the physiological information detector during a second application of the wearable application unit; determining a time point at which the waveform of the second wave signal intersects with the waveform of the packet signal as a first time point; outputting a pressure value applied to the upstream blood vessel by the wearable pressure applying unit at the first time point as a systolic pressure value; determining a time point when the packet signal has a preset amplitude as a second time point; and outputting the pressure value applied to the upstream blood vessel by the wearable pressure applying unit at the second time point as a diastolic pressure value.

Description

[0001] Literature cross-references to related applications [0002] This patent application benefits from U.S. Provisional Application 62 / 886,368, filed August 14, 2019, which is incorporated herein by reference in its entirety. technical field [0003] This patent specification belongs to a blood pressure measurement method and device, and more specifically relates to a blood pressure measurement method and device that reduce measurement errors. Background technique [0004] Cardiovascular disease (CVD) accounts for a substantial portion of deaths worldwide, and CVD includes coronary heart disease, which accounts for the majority of cardiovascular disease deaths, as well as stroke and heart failure. CVD is closely related to pathogenic factors and lifestyle. CVD is closely related to pathogenic factors and lifestyle. In addition to maintaining a healthy lifestyle, regular monitoring of blood pressure, blood sugar and cholesterol also plays an important role in preventing ...
