Detachable flexible fabric electrocardio active dry electrode capable of inhibiting motion artifacts

Abstract

The invention relates to a detachable flexible fabric electrocardio active dry electrode capable of inhibiting motion artifacts. The electrode is composed of a bonding layer, an active layer, an insulated package layer, a contact surface layer and an insulated shielding layer; hook and loop of a hook-and-loop fastener refer to the bonding layer as the first layer, a single-side flexible printed circuit board is the active layer as the second layer, insulating foam refers to the insulated package layer as the third layer, conductive cloth refers to the contact surface layer as the fourth layer,and an insulated fabric with the hollow center refers to the insulated shielding layer as the fifth layer. The detachable flexible fabric electrocardio active dry electrode capable of inhibiting motion artifacts overcomes skin stimulation and damage caused by a traditional wet electrode, can be repeatedly used and fixedly disassembled, and can be used in daily wearable devices. A first-level buffering amplification circuit with the specific active layer structure is adopted, the input impedance is effectively increased, skin-electrode impedance matching can be well performed, power-line interference and power line interference are reduced, the motion artifacts are reduced, and more accurate electrocardio signals are collected.

Description

technical field [0001] The invention belongs to the field of medical equipment (apparatus) / electrocardiogram electrodes, and in particular relates to a detachable active dry electrode for electrocardiograms which can suppress motion artifacts. Background technique [0002] ECG monitoring has very important guiding significance for the prevention of early and sudden cardiac problems. The transient or sudden abnormal ECG signals captured by ECG monitoring play a vital role in clinical diagnosis and treatment of heart diseases; the earliest ECG health monitoring can only be carried out in hospitals. With the emergence and popularization of wearable ECG monitoring equipment, more and more of us can choose to monitor ECG in real time in our daily life and keep track of our own health conditions; [0003] The electrode is a conduction device that obtains the ECG signal and contacts the ECG device with the skin. The electrode is divided into two types: wet electrode and dry electr...
