The application relates to the technical field of wearable medical devices, and particularly provides a
blood vessel hardening evaluation device,
system and method based on multi-physiological parameter fusion and
dynamic load testing, which comprises a wearing body and a
processing system integrated on the wearing body, the
processing system comprising: a
signal synchronous acquisition module for synchronously acquiring PPG signals, ECG signals and
motion measurement signals; a physiological parameter
estimation module for calculating first-type physiological parameters based on the PPG signals and the ECG signals; a comprehensive index generation module for generating a
blood vessel health comprehensive index of a user according to the first-type physiological parameters and static personal information of the user; a dynamic function evaluation module for generating a dynamic
recovery index of the user; and an
evaluation data output module for outputting final
evaluation data based on the
blood vessel health comprehensive index and / or the dynamic
recovery index. The device realizes non-invasive, dynamic and high-credibility
system evaluation of the blood vessel
health condition under the condition of convenient wearing.
