Abstract

The invention proposes an optical scanning pulse wave sensor and wearable device, an optical scanning wrist pulse wave analyzer, an optical scanning heart rate monitor, an optical scanning blood pressure monitor, an optical scanning blood vessel hardness tester, an optical scanning Type carotid artery hardness tester and pulse wave monitoring method. The pulse wave sensor includes a laser transmitter, which emits the first laser light; a branch optical waveguide component, which receives the first laser light and branches it into a second laser light and a reference light; and a light guide output component, which receives and adjusts the second laser light to form a third laser light. The laser light enables the third laser light to enter the blood vessel; the light guide input part receives and adjusts the fourth laser light reflected from the blood vessel to form the fifth laser light; the receiving optical path part receives the fifth laser light and the reference light to form the second laser light after two-way interference Six lasers. The optical scanning pulse wave sensor, related monitoring equipment and wearable device provided by the present invention can realize continuous monitoring, have high precision, good effect and low power consumption.

Description

technical field [0001] The invention belongs to the technical field of pulse wave monitoring in electronic medical equipment, relates to the use of optical devices for measurement, and in particular to a pulse wave sensor, a pulse wave monitoring method and a wearable device. Background technique [0002] Cardiovascular disease is the primary disease that currently threatens human health, and the pulse wave of the human body reflects the function of the cardiovascular system. The body's physiology, mental state, physical strength level and other information reflected by the intensity, speed and rhythm of the pulse wave can display personal health status, or serve as auxiliary monitoring for other medical instruments, and provide diagnostic reference for doctors, etc. [0003] Currently, pulse wave monitoring methods mainly use photoplethysmography (PPG) or the principle of piezoelectric sensors to indirectly reflect changes in pulse waves. Photoplethysmography uses the ligh...
