Fabric electrode and intelligent electrocardiograph

Abstract

The invention provides a fabric electrode and an intelligent electrocardiograph. The fabric electrode comprises hydrophilic conductive cloth and a liquid storage structure for wetting hydrophilic fiber, wherein the hydrophilic conductive cloth is formed by knitting conductive fiber and hydrophilic fiber, and the liquid storage structure is in contact with the hydrophilic conductive cloth. When thefabric electrode is used, the liquid storage structure stores liquid, and the hydrophilic conductive cloth is provided with the hydrophilic fiber, so that the hydrophilic fiber can automatically absorb the liquid in the liquid storage structure, it is ensured that the surface of the hydrophilic conductive cloth is always wet in dozens of hours, and then good conductive contact between the hydrophilic conductive cloth and the skin is ensured. Therefore, the electrode signal acquisition accuracy is improved, meanwhile the fabric electrode doses not need to be wetted repeatedly and is convenientto use. In addition, the fabric electrode provides stable signals and is few prone to the influence from pressure and skin state.

Description

technical field [0001] The invention relates to the technical field of medical devices, and more specifically, relates to a fabric electrode, and also relates to an intelligent electrocardiographic clothing. Background technique [0002] The fabric electrodes on the existing smart electrocardiogram clothes are composed of conductive cloth and foam, and the conductive cloth is made of conductive fibers; the fabric electrodes are easily affected by the dry and wet state of the skin, and the electrode signal acquisition is relatively stable for wet skin; Due to the high surface impedance of dry skin, sometimes even no signal can be collected; the fabric electrode needs to be wetted with water before use, and as the water evaporates, the contact state between the electrode and the skin will gradually deteriorate, resulting in accurate electrode signal collection Poor performance and inconvenient to use.

[0002] The fabric electrodes on the existing smart electrocardiogram clothes are composed of conductive cloth and foam, and the conductive cloth is made of conductive fibers; the fabric electrodes are easily affected by the dry and wet state of the skin, and the electrode signal acquisition is relatively stable for wet skin; Due to the high surface impedance of dry skin, sometimes even no signal can be collected; the fabric electrode needs to be wetted with water before use, and as the water evaporates, the contact state between the electrode and the skin will gradually deteriorate, resulting in accurate electrode signal collection Poor performance and inconvenient to use

[0003] In addition, in order to make good contact, the conductive cloth needs to be supported by foam; the fabric electrode is susceptible to pressure (different degrees of ECG suit tightening, human breathing and other factors will cause the pressure between the fabric electrode and the skin surface to fluctuate) , resulting in changes in the contact area between the conductive cloth and the skin (the contact area is large when the pressure is high, and the contact area is small when the pressure is small), resulting in large noise and clutter in the collected electrode signals

Moreover, when the ECG suit is tightened, the fabric electrodes are tightly pressed against the skin surface, causing discomfort to the human body, and in severe cases, the risk of local thrombosis
