Wireless portable and wearable ECG detector capable of suppressing motion interference

Abstract

The invention relates to a wireless, portable and wearable electrocardiogram detector capable of restraining motion interference. The wireless, portable and wearable electrocardiogram detector comprises a simulation processing module, a control module and a power supply module; the power supply module supplies power to the simulation processing module and the control module; the simulation processing module comprises an electrocardiogram detection channel, a skin electrode contact impedance detection channel and a human body voltage and current driving channel, and the electrocardiogram detection channel, the skin electrode contact impedance detection channel and the human body voltage and current driving channel are used for collecting electrocardiogram signals containing the motion interference, collecting skin electrode contact impedance signals caused by motion and providing human body common-mode voltage and alternating voltage current respectively; the control module comprises an analog-digital converter, a microcontroller and a digital signal processor; the input end of the digital signal processor receives digital signals obtained from the electrocardiogram signals containing the motion interference; the reference end of the digital signal processor receives digital signals obtained from the skin electrode contact impedance signals caused by the motion; and the electrocardiogram signals without the motion interference are obtained according to the adaptive algorithm. By means of the wireless, portable and wearable electrocardiogram detector, the good and reliable electrocardiogram signals can be obtained in the motion state.

Description

technical field [0001] The invention relates to a human body health monitoring instrument and a mobile human body electrocardiogram sign monitoring instrument in the technical field of medical equipment, in particular to a wireless portable and wearable electrocardiogram detector capable of suppressing motion interference. Background technique [0002] With the increase in the life expectancy of the global population, the aging trend of countries around the world has become very obvious. The mechanism by which aging affects medical and health expenditures mainly favors the elderly population through medical technology, medical insurance and other resources, and the health status of the elderly determines the total amount of medical insurance they spend and the number of times they use advanced medical technology. Developed countries have taken measures to improve the health status of the aging population as much as possible, and to control the excessive growth of medical and...
