Problems solved by technology

[0003] At present, the ECG electrodes commonly used at home and abroad are made of precious metal silver, so the cost is high, and the conductive paste is easy to dry
Disposable electrocardiogram electrodes that are used now have the following disadvantages: because the colloidal area is relatively small, the contact with the skin is also relatively small, so the electrical conductivity is not very good; the adhesive will dry after a long time; the viscosity of the adhesive is not very good and The patient is easy to shift after sweating; the non-woven fabric is slightly irritated and allergic to the skin because of the self-adhesive; the operation is complicated, and there is a little pain when sticking the skin and peeling off the skin; the electrode potential is stable, and the ECG waveform is clear but unstable ; High production cost

Abstract

The invention relates to a disposable novel electrocardiogram monitoring electrode. Hydrogel used by the electrode comprises main components as follows: glycerine, arabic gum, polyvinyl acetate emulsion, potassium chloride, acrylic acid, pure glue, waterborne polyurethane, dimethyl acrylamide, polyacrylamide, N-polyacrylamide, initiator, crosslinking agent and the like. The electrode produced by use of the hydrogel has the advantages that the electrode is good in glue stickiness and free from residue as well as displacement and can not irritate skin or cause allergy; gel can not be dried and can keep good contact with skin for a long time; and the electrode is convenient to operate, stable in electrode potential, clear and stable in electrocardiogram waveform, low in production cost, and the like.

Description

technical field [0001] The invention relates to a new disposable electrocardiographic monitoring electrode, in particular to a new disposable electrocardiographic monitoring electrode with low cost and avoiding cross infection. Background technique [0002] Disposable new ECG monitoring electrode is an important and commonly used biomedical sensor. It is very convenient to use, does not need to be sterilized, sticks firmly, and can avoid cross-infection, so it has been paid special attention to. In the European Union and some developed countries, all medical institutions equipped with ECG monitoring systems have fully used disposable new ECG monitoring electrodes. [0003] At present, the electrocardiographic electrodes commonly used at home and abroad all use precious metal silver as the raw material, so the cost is high, and the conductive paste is easy to dry. Disposable electrocardiogram electrodes that are used now have the following disadvantages: because the colloida...
