Cuffless ambulatory blood pressure monitoring equipment based on electrocardio signals and impedance signals

Abstract

Cuffless ambulatory blood pressure monitoring equipment based on electrocardio signals and impedance signals can be used for continuously monitoring electrocardio signals, blood pressure signals and blood flow signals in an ambulatory mode and comprises an electrocardio signal monitoring unit, an impedance signal monitoring unit, a physiological signal analytic processing unit and a physiological parameter information displaying and transmitting unit. By the monitoring equipment, the electrocardio signals can be monitored, the impedance signals of blood flow can be reflected, and the transmitting time of pulse waves can be calculated according to the electrocardio signals and the impedance signals, so that blood pressure can be continuously measured in an ambulatory and beat-to-beat mode. The shortcoming that the existing arm type or wrist type ambulatory sphygmomanometer based on an oscillometric method requires to be inflated and deflated, is high in power consumption and cannot be continuously monitored in a beat-to-beat manner is overcome.

Description

technical field [0001] The invention relates to the field of health care monitoring, in particular to a cuffless dynamic continuous blood pressure monitoring device based on electrocardiographic signals and impedance signals. Background technique [0002] With the rapid development of social economy, people pay more and more attention to health status; especially with the growth of aging population and the increasing number of chronic diseases, the number of hypertensive patients is increasing. The existing arm or wrist ambulatory blood pressure Because the monitoring equipment needs to be inflated and deflated, it has great influence on the monitored person, cannot realize continuous monitoring of arterial blood pressure and high power consumption, and is especially not suitable for dynamic continuous blood pressure monitoring during sleep. [0003] The present invention arranges several ECG monitoring electrodes on the chest of the monitored person, arranges several impeda...
