Problems solved by technology

Existing disposable electrocardiographic monitoring electrodes have the following disadvantages: the colloidal area of ​​the electrode body is relatively small, so the contact with the skin is also relatively small, and the conductivity is average; the adhesive will dry after a long time, and the adhesiveness is not very good. The patient is easy to shift after sweating; because the non-woven fabric has self-adhesive, it is slightly irritating and allergic to the skin, and some elderly patients are prone to different degrees of sticking parts of the electrodes after placing disposable ECG electrodes for a long time. Injuries, such as local bleeding, itching, and even papules and blisters on the basis of erythema, and contact dermatitis; the operation is complicated, and there is a little pain when sticking the skin and peeling off the skin; the production cost is high, the use time is short, and the hydrogel used is environmentally friendly poor performance
[0004] Due to the existence of the above shortcomings, the performance of the existing disposable ECG monitoring electrodes is mostly unsatisfactory, and cannot keep up with the ever-changing needs of the development of medical monitoring equipment. The electrodes have many interferences, high noise, unclear ECG waveforms and poor stability. Affects the accurate diagnosis of diseases by medical staff

Abstract

The invention discloses a kind of biological intelligent glue. The biological intelligent glue disclosed by the invention is prepared from sodium alga acid, chitosan, polyvinyl alcohol, glycerin, carbomer, N, N-methylene bisacrylamide, and dimethyl 2,2'-azobis(2-methylpropionate) in a weight ratio. The biological intelligent glue disclosed by the invention is strong in electrical conductivity, small in electrical resistivity, and biodegradable; and when the biological intelligent glue is used as a gluing and conductive medium for manufacturing a disposable electrocardiograph monitoring electrode, the biological intelligent glue disclosed by the invention is not dried and good in adhesion, and can keep in good contact with the skin for a long time, therefore, the electrode interference is less, the electrode potential is stable, and the electrocardiograph waveform is clear and stable; the biological intelligent glue can be adhered without residues and has no stimulation to the skin; and the biological intelligent glue is low in production cost and high in environmental performance, and has extremely practicability and popularization values.

Description

technical field [0001] The invention relates to a biological intelligent glue, in particular to a biological intelligent glue with strong conductivity, low resistivity and microbial degradation. Background technique [0002] At present, disposable ECG monitoring electrodes are mainly used with ECG machines and monitors to receive human ECG information and to monitor patients' heart rate, pulse and other information. It is an important and commonly used biomedical sensor because of its convenient use. , without disinfection, can avoid the characteristics of cross-infection. [0003] The disposable ECG monitoring electrode mainly includes an electrode body, an electrode plug terminal and a lead wire electrically connected between the electrode body and the electrode plug terminal. The electrode body is generally composed of non-woven fabric, release paper, and hydrogel. Existing disposable electrocardiographic monitoring electrodes have the following disadvantages: the colloi...
