Description
Technical Field
The invention belongs to the technical field of wearable electrocardiograph monitoring equipment, and particularly relates to a wearable multi-guide-state electrocardiograph monitor.
Background
The wearable multi-lead electrocardiosignal aims at enabling an electrocardio detection technology to go into thousands of households from a hospital, and collecting dynamic electrocardiosignals of a patient in a wearing mode so as to realize the aim of 24-hour uninterrupted electrocardiosignal detection and analysis. The equipment is complementary with the current medical short-term electrocardiographic examination method, and timely captures sudden physical discomfort caused by unknown reasons for a long time, timely discovers abnormal conditions of the heart, and prompts the attention and medical seeking of patients. Existing wearable dynamic electrocardiographic monitoring devices can be divided into two types, namely single-lead and multi-lead according to the number of channels. The electrocardiosignal is a vector with the size and the direction, but most of the existing dynamic electrocardiograph monitors are single-lead equipment, only electrocardiograph information with single dimension can be obtained, and the accuracy and the comprehensiveness are limited. Compared with single-lead electrocardiograph, the multi-lead electrocardiograph can obtain electrocardiograph information with multiple dimensions, can monitor electrocardiograph conditions of a human body more comprehensively, and can judge lesion positions of hearts. However, the conventional multi-lead dynamic electrocardiograph monitor is based on a clinically used 12-lead system, and four limb electrodes are distributed in a large range, so that many difficulties are brought to the research and development and the use of the household wearable multi-lead electrocardiograph monitor, and the system mainly comprises:
1. The conventional multi-lead system has the defects of multiple electrodes and wide distribution range, not only causes difficulty for placing and fixing the electrodes, but also easily causes the problems of arrangement, winding and storage of lead wires.
2. The electrodes are distributed and dispersed, and are more easily disturbed by movement.
3. Existing multi-lead electrocardiographs include a plurality of (at least 4) electrocardiographic electrodes, typically carried on clothing, using wearable electrodes represented by textile electrodes. Mainly based on the clothing (such as tights, etc.) of high elasticity surface fabric, the electrocardio electrode is bound on the skin surface by the elasticity of clothing. The tightness degree of the high-elasticity clothes is closely related to the human body shape and wearing habit, the universality is limited, the comfort is poor, the high-elasticity clothes are especially not suitable for monitoring sleep states, and the tightening sense of wearing is difficult to avoid while the tight fit of a plurality of groups of electrodes and the skin is ensured.
4. The shape and wearing habit of human body are different, and the electrode position in the multi-lead electrocardiograph clothes is relatively fixed, so that the flexible adjustment is difficult, and therefore, a single device is difficult to adapt to different crowds at the same time.
5. The multi-lead electrocardiograph monitor taking clothes as a carrier cannot meet the diversity and personalized wearing requirements of users. In addition, the wearing comfort is reduced due to the fact that the leads of the multi-lead electrocardiograph garment are more.

Detailed Description
The invention is described in further detail below with reference to the examples and with reference to the accompanying drawings.
The potential difference formed by the myocardial cells during the depolarization or repolarization process has both magnitude and direction, called the electrocardiographic vector. The projection of the electrocardiographic vector onto the different guide axes forms an electrocardiogram of each guide. The multi-lead electrocardiogram reflects the change in the magnitude and direction of the instantaneous integrated electrocardiographic vector. The limb electrode placement positions of the conventional 12-lead dynamic electrocardiogram are respectively as follows:
The RA electrode is 1/3 of the outer part of the right subclavian fossa;
The LA electrode is 1/3 of the outer part of the left subclavian fossa;
LL electrode at left collarbone midline 7 th rib edge;
the RL electrode is on the 7 th rib edge of the right collarbone midline;
The triangle enclosed by the RA, LA and LL electrodes is called Einthoven triangle, which forms frontal plane six-axis lead system.
In the invention, the position of the LA electrode is kept unchanged, the RA electrode and the LL electrode are respectively moved in proportion to the direction of the LA electrode, wherein the RA electrode is horizontally moved to the position of the central line of the sternum, and the electrode on the sternum is less susceptible to muscle activity; correspondingly, moving LA up to the fifth rib; the right leg driving electrode RL is moved onto the mid-sternum line. The triangle formed by the three groups of electrodes after movement is basically similar to the triangle formed by the electrodes before movement, thus forming a reduced lead system based on the frontal plane six-axis lead system, being capable of keeping the basic characteristics (waveform direction, relative strength and the like) of each lead electrocardiogram and greatly reducing the distribution range of the electrocardio electrodes. The RL electrode is used as a right leg driving electrode and is mainly used for improving the quality of an electrocardiogram and does not influence the characteristics of the electrocardiogram, so that the position of the RL electrode can be moved towards the LA direction. As shown in fig. 1, the positions of the limb electrodes after shrinking in the present invention are:
The LA electrode is 1/3 of the outer part of the left subclavian fossa;
LL electrode is on the 5 th rib margin of left collarbone midline;
the RA electrode is arranged on the midline of the sternum and is flush with the LA;
The RL electrode intersects the 5 th rib edge at the midline of the sternum.
In addition, the chest lead takes the central electric end as the negative electrode and the chest electrode as the positive electrode, and in the reduced lead group, the chest lead electrode position is kept unchanged, so that the electrocardio waveform with the height consistent with the standard lead can be obtained.
