Problems solved by technology
[0003] At present, most of the ECG tests need to be tested in the hospital, and most of the ECG test equipment on the market are mostly single-lead, not medical 12-lead. In addition, the portable real-time ECG belt is hard Close contact cannot be formed between the electrodes and the body, and the signal-to-noise ratio is small
Due to the lack of medical knowledge of most users and rural doctors, there is a large deviation in the positioning of the opaque fabric band of the traditional ECG belt

Embodiment Construction
[0028] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.
[0029] like figure 1 As shown, the electrode types commonly used in related technologies include Ag / AgCl electrodes, dry electrodes, microneedle electrodes, or dry electrodes with insulators. Among them, Ag / AgCl electrodes commonly used in the market may have rejection reactions. Disadvantages such as not being comfortable enough to wear; traditional dry electrodes are not in close contact with the skin, and are generally made of hard metal, resulting in inconvenient and uncomfortable wearing; microneedle electrodes need to penet...

The invention discloses a method and device for preparing a 12-lead transparent electrocardiostrip based on a graphene electrode, which are characterized by comprising the following steps: preparing agraphene oxide solution; dripping the graphene oxide solution onto a tattoo substrate so that the graphene oxide solution is volatilized on the tattoo substrate to form a graphene oxide film; reducing the graphene oxide film through laser to form a graphene electrode pattern; stripping the unreduced graphene oxide film through an aqueous solution to obtain a tattoo type graphene electrode; transferring the tattoo type graphene electrode onto a transparent viscous electrocardiostrip pre-distributed with a circuit to obtain the 12-lead transparent electrocardiostrip. According to the method, the multilayer graphene electrode is tightly adhered to the skin to reduce impedance and improve signal quality; meanwhile, the electrode can be transferred to a viscous transparent belt of the pre-arranged circuit, so that the positioning of the electrocardiostrip is facilitated; the electrocardiostrip is also matched with a machine for learning to achieve real-time judgment of the electrocardio signal.
Description
technical field [0001] The invention relates to the technical field of biological electrodes, in particular to a preparation method and device for a 12-lead transparent electrocardiographic belt based on graphene electrodes. Background technique [0002] With the intensification of aging, how to better serve the elderly and understand the physical condition of the elderly anytime and anywhere has become an important social issue. At the same time, with the development of social economy, people hope to have a deeper understanding of their physical condition. learn. As an important indicator of human condition, ECG can reflect the physiological condition of human body and is the early sign of many diseases. [0003] At present, most of the ECG tests need to be tested in the hospital, and most of the ECG test equipment on the market are mostly single-lead, not medical 12-lead. In addition, the portable real-time ECG belt is hard Close contact cannot be formed between the elec...
