Abstract

The invention discloses a blood pressure determination method and device. The blood pressure determination method includes: acquiring a pulse wave signal and an electrocardiosignal of a user; extracting a feature parameter of the user from the acquired pulse wave signal and the acquired electrocardiosignal of the user; establishing a feature vector of the user according to the extracted feature parameter of the user and predetermined personal information of the user; and determining a blood pressure value of the user according to the feature vector of the user and a relation model between thepre-established feature vector and the blood pressure value. The blood pressure determination method can acquire the blood pressure value of the user according to the feature vector of the user and the relation model between the pre-established feature vector and the blood pressure value, and can achieve non-cuff measurement of the blood pressure value. The feature vector includes the personal information of the user and the feature parameter determined according to the pulse wave signal and the electrocardiosignal, calibration of each person can be avoided in a blood pressure measurement process, the use process is convenient, and the measurement result is more accurate.

Description

technical field [0001] The invention relates to the technical field of health monitoring, in particular to a method and device for determining blood pressure. Background technique [0002] Hypertension is a common disease of cardiovascular disease. The number of hypertensive people in my country is large, and it is on the rise. Accurate blood pressure measurement is of great significance for the discovery, management and treatment of hypertension and other diseases. Traditional blood pressure measurement includes two types: invasive and non-invasive. Invasive measurement, in which a catheter is inserted into the artery and the arterial pressure is measured directly through a transducer, is invasive and expensive, and not suitable for routine home measurements. Non-invasive methods mostly use the cuff to inflate and deflate, and use Korotkoff sounds or oscillatory waves to measure blood pressure. However, the inflation and deflation of the cuff not only easily causes damag...
