Description

ECG signal acquisition electrode, device and monitoring system for wearable electronic clothing

technical field

The disclosure belongs to the technical field of bioelectrophysiological signals, and relates to an electrocardiographic signal acquisition electrode, device and monitoring system of wearable electronic clothing.

Background technique

The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art.

Electrocardiography (ECG) is one of the most widely used vital sign sensing and health monitoring methods, and it can provide useful diagnostic information about the cardiovascular system in clinical medical diagnosis. To a certain extent, it can also be used as a powerful indicator of some specific physiological and pathological conditions in humans. With the increasing frequency of coronary artery disease over the past decades, continuous monitoring of ECG signals in high-risk patients can play an important role in the immediate detection of pathological features and arrhythmias. Using this concept, any deviation of an individual's health status from its standard can be detected and sent to the health center for further analysis and prevention. Studies have shown that if it does not interfere with daily activities, this instant online ECG monitoring can improve the diagnosis and treatment of some of the most common heart diseases to a certain extent, and is very helpful for the timely treatment of patients.

Currently, ECG monitoring can be accomplished in a number of ways. The electrodes of traditional clinical ECG systems are silicone patches, which are glued to the skin with gel. However, with such traditional silicone patches this usually requires cleaning the attachment site and, if necessary, shaving off parts of the hair or treating certain parts of the body. In this way, it is possible to use electrodes in pads with gel in the middle to provide a conductive medium for charge transfer between the electrodes and the body. To keep the electrodes in place, additional tape should be applied to help secure them.

The inventor found during the research that it would bring great inconvenience to testers during use, and may cause skin irritation, allergic reactions and inflammation due to the toxicological problems of the gel in long-term treatment. Additionally, as the gel dehydrates over prolonged use, signal quality will degrade and gel replacement is usually not feasible. Furthermore, since it is difficult to keep the adhesives completely separated from each other for a long time, cross-coupling between adjacent-electrode positions can occur through leakage currents. Therefore, wet ECG electrode systems may not be suitable for long-term ECG monitoring.
