Blood pressure detection system and method

Abstract

The invention provides a blood pressure detection system. The blood pressure detection system includes: an electrocardiographic signal acquisition unit, a pulse wave signal acquisition unit, a multi-signal acquisition unit, a synchronizing signal unit, and a signal processing unit; the synchronizing signal unit generates and sends a synchronizing signal to the electrocardiographic signal acquisition unit, the pulse wave signal acquisition unit and the multi-signal acquisition unit; the electrocardiographic signal acquisition unit and the pulse wave signal acquisition unit encode the received synchronizing signal to an acquired signal; the multi-signal acquisition unit performs synchronous processing on an acquired signal on the basis of the received synchronizing signal; and the signal processing unit receives the electrocardiographic signal and the pulse wave signal which are synchronous-processed, and continuously calculates the blood pressure of a user.

Description

technical field [0001] The present disclosure relates to a blood pressure detection system and a blood pressure detection method, in particular to a non-invasive and continuous blood pressure detection system and method. Background technique [0002] With the increasingly fast-paced social life, people's health problems are becoming more and more prominent. Chronic diseases such as cardiovascular and cerebrovascular diseases and high blood pressure have become killers of human health. Even these diseases caused by abnormal blood pressure are increasingly troubled by young people. Therefore, convenient and easy-to-use health monitoring equipment has become an urgent demand of the society. In particular, a portable or household blood pressure detection system is increasingly required for people's daily health detection. [0003] At first, people used blood vessel sound auscultation to detect blood pressure, that is, the method of pressing the air pressure after wrapping a com...

Problems solved by technology

However, this existing acquisition system has great constraints on users

However, in order to eliminate this constraint, when the ECG signal and the blood oxygen signal are collected independently between different circuit boards, since the two units are on different circuit boards, the collected signals are not aligned on the time axis. The asynchrony of the ECG signal and the blood oxygen signal will cause a large error in the PTT result, thus resulting in inaccurate blood pressure calculation results

Moreover, the measurement results of this separate processing method cannot be converted into electronic data in a unified format, and cannot be transmitted to the cloud database for storage and further analysis and processing through convenient networking means.
