Description

12-Lead electrocardiograph monitoring garment based on bionic embroidery electrode Technical Field The invention relates to the technical field of textile material wearable medical equipment, in particular to a 12-lead electrocardiograph monitoring garment based on a bionic embroidered electrode. Background Cardiovascular diseases are main lethal causes in the global scope, have the characteristics of long-term property, accumulation property and sporadic property, and are difficult to meet the requirement of daily continuous monitoring in routine medical examination, so that the wearable human electrocardiosignal real-time monitoring equipment becomes an important support for clinical diagnosis and household health management, and an electrocardiogram is a routine means for predicting and diagnosing the cardiovascular diseases as a core mode for detecting the heart electric activity. The traditional clinical dynamic electrocardiogram monitoring generally adopts a 12-lead Ag/AgCl gel electrode scheme, and is used by matching with conductive paste, a recorder is connected through a plurality of lead wires, 4 limb electrodes (RA, LA, LL, RL) and 6 chest wall electrodes (V1, V2, V3, V4, V5 and V6) are used for electrocardio signal acquisition, and the monitoring mode has the defects that the conductive paste can be dried gradually after long-time use, so that the interface impedance of a skin-electrode is increased, the signal quality is reduced, skin itch and anaphylactic reaction are easily caused by gel and adhesive, the method is not suitable for users needing long-time continuous monitoring or skin sensitivity, the positioning of the electrodes needs professional operation, the patient is difficult to accurately finish, and the wearing process is tedious and time-consuming. In addition, sweat distribution of human body is uneven, in electrode placement positions, there are hyperhidrosis areas (electrodes V5, V6, RA, LA), midhidrosis areas (electrodes V1, V2, V3, V4), hypohidrosis areas (electrodes RL, LL), sweat affects adhesion of the electrodes, damages electrode-skin interface, and reduces quality and stability of electrocardiosignal acquisition. In order to solve the problems, an intelligent electrocardiograph monitoring garment integrating an electrocardiograph monitoring function is generated, and becomes a main stream direction of technical development. In the prior art, the Chinese patent CN 214907064U adopts a fabric electrode and is connected to a detachable monitoring terminal through a conductive cloth strip, so that the repeated use of the electrode and the detachment of the monitoring terminal are realized, and the Chinese patent CN 221813966U improves the wearing experience and the influence of the displacement of the electrode on the monitoring through the design of a front zipper and a girdle. The existing intelligent electrocardio monitoring clothing technology still does not break through the core technical bottleneck, and has a plurality of problems to be solved, namely, firstly, the technology is not designed in a targeted manner aiming at the difference of human sweat area, under the dynamic activity or sweating environment, the impedance of an electrode-skin interface is easy to generate great fluctuation, so that electrocardiosignal noise is large, baseline drift is obvious, the stability and accuracy of monitoring are insufficient, the dual interference of the difference of sweat area and the dynamic activity on signal acquisition cannot be solved, secondly, a part of schemes still use disposable electrode plates, the reusability is poor, skin allergy is easy to cause, the skin friendliness requirement of long-range continuous monitoring cannot be met, thirdly, the whole technical scheme is difficult to consider the high fidelity of electrocardiosignals under long-range and dynamic monitoring, and the convenience and the comfort of use of the wearing process are greatly different from the practical application requirement of daily autonomous electrocardio monitoring. Therefore, the 12-lead electrocardiograph monitoring device which can adapt to human sweat distribution differences, give consideration to dynamic monitoring signal stability and wearing comfort and can realize autonomous and convenient operation is developed, and becomes a key direction for solving pain points in the prior art and meeting daily monitoring requirements of cardiovascular diseases. Disclosure of Invention Aiming at the problems in the prior art, the invention provides the 12-lead electrocardiograph monitoring garment based on the bionic embroidered electrode aiming at the distribution of the sweating areas of a human body, and the electrocardiograph monitoring garment realizes continuous and stable acquisition of 12-lead electrocardiograph signals under multiple motion states by combining the bionic embroidered electrode with excellent dry/wet state adhesiveness and dynamic sensing stability with an opt
