Electrocardiograph monitoring device and system and preparation method of MEMS spherical cap dry electrode array

Abstract

The invention discloses an electrocardiograph monitoring device and system and a preparation method of an MEMS spherical cap dry electrode array. The electrocardiograph monitoring device comprises the MEMS spherical cap dry electrode array and an electrocardiograph signal collection and control module. The MEMS spherical cap dry electrode array is used for extracting a body surface electrocardiograph signal and transmitting the body surface electrocardiograph signal to the electrocardiograph signal collection and control module through a lead wire. The electrocardiograph signal collection and control module is used for performing preprocessing including conditioning filtering on the obtained body surface electrocardiograph signal, converting an analog electrocardiograph signal into a digital electrocardiograph signal and filtering away power frequency interference. By the adoption of an MEMS technology, the flexible spherical cap dry electrode array is processed to serve as a collecting electrode of the electrocardiograph signal without conducting resin and skin stimulation. The electrocardiograph monitoring device is suitable for long-term electrocardiograph monitoring and can collect multiple pieces of physiological information; meanwhile, the utilization rate of a mobile terminal is increased, a feedback result of a doctor is obtained in time, and the distance between doctors and patients is closer.

Description

technical field [0001] The present invention relates to a method for preparing an ECG monitoring device, system and MEMS spherical crown dry electrode array, in particular to an ECG monitoring device, system and MEMS spherical crown dry electrode array based on a flexible PDMS substrate Array preparation method. Background technique [0002] The rapid development of the economy and medical and health services has prompted people to pay more attention to their own health status, and people's health concept has gradually changed from simple "passive treatment" to "active prevention by using various health promotion methods". China is gradually entering an aging society. Among all the susceptible diseases of the elderly, cardiovascular disease is the disease with the highest morbidity, mortality, disability and complications. Cardiovascular disease is a chronic disease with slow development, strong concealment and high sudden risk factor. Early detection of signs of heart di...

Problems solved by technology

[0008] (1) Ag / Agcl wet electrodes are still used for ECG collection, which irritates the skin, and the quality of the measured ECG signal gradually deteriorates with time, and the wet electrodes are not easy to integrate

[0009] (2) The collected ECG signal is only passed to the doctor through simple filtering and denoising processing, and cannot be analyzed for ECG characteristics, which is not convenient for the patient to know the state of his heart in time. On the other hand, it also increases the workload of the doctor. Conducive to the timely treatment of critically ill patients

[0010] (3) Smartphones only use the Bluetooth transmission function to transmit ECG data, which is a waste of resources
