Problems solved by technology

When the pulse signal is disturbed, it is easy to make mistakes in the direct identification of the pulse signal, resulting in the wrong calculation of the pulse envelope, which in turn leads to the wrong calculation of the blood pressure

Abstract

A method for measuring blood pressure, comprising: detecting a user's pulse signal (S1); decomposing the pulse signal into N decomposed signals within a preset frequency range, where N≥1 (S2); calculating the differential sequence mean of pulse maximum sequences in each decomposed signal, and using the decomposed signal with the smallest differential sequence mean as a valid pulse signal (S3); and calculating the user's blood pressure according to the valid pulse signal (S4). Accordingly, further disclosed is an apparatus for measuring blood pressure. The method for measuring blood pressure can improve the accuracy of blood pressure measurement.

Description

technical field [0001] The invention relates to the technical field of signal detection and processing, in particular to a method and device for measuring blood pressure. Background technique [0002] Blood pressure (BP) is the pressure exerted on the wall of the blood vessel when the blood flows in the blood vessel, and it is the power to push the blood to flow in the blood vessel. When the ventricle contracts, blood flows from the ventricle into the artery. At this time, the pressure of the blood on the artery is the highest, which is called systolic blood pressure (SBP). Ventricular diastole, arterial blood vessels elastically retract, blood continues to flow forward slowly, but blood pressure drops, and the pressure at this time is called diastolic blood pressure (DBP). Since blood vessels are divided into arteries, capillaries, and veins, there are also arterial blood pressure, capillary blood pressure, and venous blood pressure. Generally speaking, blood pressure ref...
