Abstract

The invention relates to a physiological parameter monitoring system signal amplifier, in particular to an electrocardiosignal amplifier suitable for an electrode with a spinning structure, and belongs to the technical field of medical devices and signal processing. The physiological parameter monitoring system signal amplifier mainly comprises a five-fold first-stage amplification circuit, a high-pass filter circuit with the main frequency of 0.05HZ, a 50HZ trap circuit, a 100HZ low-pass filter circuit, a 100HZ trap circuit, a secondary amplification circuit and an addition modification circuit. The physiological parameter monitoring system signal amplifier can ensure that electrocardiosignals transmitted by the electrodes are effectively amplified, and meanwhile, external interference can be greatly inhibited; null drift and noise caused by movement of a human body are eliminated.

Description

technical field [0001] The invention relates to a signal amplifying circuit of a physiological parameter monitoring system, in particular to an electrocardiographic signal amplifier used for textile structure electrodes, belonging to the technical field of medical equipment and signal processing. Background technique [0002] The morbidity and mortality of cardiovascular disease in the Chinese population are on the rise. It is estimated that there are 230 million people with cardiovascular disease in China, including 200 million people with hypertension, 2 million people with myocardial infarction, and 4.2 million people with heart failure. Nearly 3 million people die from cardiovascular diseases every year in my country, accounting for one third of the total number of deaths from diseases in China. Half of people who die from cardiovascular disease have high blood pressure. [0003] The human circulatory system consists of the heart and blood vessels, and its main functio...
