Method and apparatus for cuff less blood pressure monitoring based on simultaneously measured ECG and PPG signals designed in wristband form for continuous wearing

摘要

The present invention relates to the method and apparatus for cuffless measuring of blood pressure value from one limb of a subject. Proposed herein method of measuring blood pressure based on pressure calculation method from pulse wave velocity (PWV) value, which does not require any external device for calibration. PWV is calculated from three main signals: the heart electrical activity signal (ECG) and two photoplethysmographic signals (PPG). The described herein device comprises a set of ECG electrodes, optical and electronic sensors, a microcontroller for signal processing, a power supply unit, user interface means, and a wireless communication unit. The device is designed to monitor blood pressure and can be used for medical purposes or self-monitoring in everyday life.
