Electrocardio dry electrode employing flexible perforated conductive rubber

Abstract

The invention discloses an electrocardio dry electrode employing flexible perforated conductive rubber. The electrode comprises a substrate layer, a filling layer, a contact surface layer and an insulating barrier layer, wherein an elastic flexible fabric is the substrate layer; flexible perforated medical conductive rubber sheet is the filling layer; conductive sponge is the contact surface layer; a central hollowed-out insulating fabric is the insulating barrier layer; the substrate layer is glued with the filling layer through mucilage glue, the insulating barrier layer is glued with the filling layer through the mucilage glue, and the filling layer is glued with the contact surface layer through a conductive adhesive. According to the dry electrode, irritation and damage of a traditional wet electrode to the skin can be overcome; the dry electrode is not a disposable electrode and can be worn and used for a long period of time; the breathability is improved by adopting the perforated rubber; by adopting the flexible conductive sponge, the dry electrode can be effectively laminated with a skin topology, and the wear comfort is improved; and by adopting a conductive rubber-conductive sponge structure, signal noise during dynamic wearing is effectively reduced and the effect of a motion artifact is reduced.

Description

technical field [0001] The invention belongs to the field of medical equipment (apparatus) / electrocardiogram electrodes, in particular to a flexible conductive rubber electrocardiogram dry electrode with holes. Background technique [0002] In today's society, heart disease is the number one killer of human health. 1 / 3 of the world's population deaths are caused by heart disease, while hundreds of thousands of people die of heart disease every year in my country. Heart disease is the most likely disease in cardiovascular and cerebrovascular diseases to endanger the health and life of middle-aged and elderly people. Long-term and dynamic observation of early and sudden heart disease to capture short-term non-sustained abnormal ECG changes, especially transient arrhythmia and transient myocardial ischemic attack symptoms, which are useful for diagnosing heart disease, judging curative effect and Saving lives is critical. [0003] According to whether conductive gel is used,...

AI Technical Summary

Problems solved by technology

At present, the disposable conductive gel wet electrode is commonly used in medical treatment to detect ECG. The disadvantage of the wet electrode is that its preparation is complicated, and the conductive gel gradually dries with time, causing measurement errors, easily causing skin allergies, and affecting comfort. Not suitable for long-term monitoring

However, it does not fundamentally solve the negative impact of wet electrodes on the user's skin

At the same time, users of wet electrodes with holes cannot wear them for a long time

[0006] Existing dry electrodes can monitor the ECG signals in the static state of the human body very well, but dry electrodes are generally metal hard plates, which cannot fit the skin topology well, and the wearing comfort is poor. Prone to motion artifacts when exercising
