Background technique

The electrocardiogram function can automatically record the bioelectrical signal (cardiac signal) generated by the myocardial excitement when the heart is active, and is a medical electronic instrument commonly used in clinical diagnosis and scientific research. Before the heart beats, the myocardium is first excited, and a weak electric current is generated during the exciting process, and the electric current is conducted to various parts through the human body tissue. Due to the different tissues of different parts of the body and the different distances between each part and the heart, various parts of the human body surface show different potential changes. The relationship between the surface potential and time generated by the electrical activity in the human heart is called ECG. An electrocardiograph is an instrument that records these physiological electrical signals. Generally, according to the number of synchronous output channels of the recorder, it is divided into: single-channel, three-channel, six-channel and twelve-channel ECG machines.

The unipolar chest lead fixes a measuring electrode at zero potential (central terminal method), and connects the central terminal to the negative terminal of the electrocardiograph to become an irrelevant electrode. The other electrode is connected to the positive end of the tracer and is used as a probe electrode, which can be placed on different parts of the chest wall. Constitute 6 kinds of unipolar chest leads respectively, and the positions of the electrodes are: V1, the fourth intercostal space on the right border of the sternum; V2, the fourth intercostal space on the left border of the sternum; V3, at the midpoint of the line connecting V1 and V4; V4, the left Fifth intercostal space on the midclavicular line; V5, on the left anterior axillary line at the same level as V4; V6, on the midaxillary line at the same level as V4.

The use of electrocardiographs is very common in clinical work. There are many chest lead wires (usually 6 or more) and they are long.

There is a need for an easy-to-use electrocardiogram lead wire connection structure that is convenient to obtain materials, easy to manufacture, easy to operate, saves time and effort, effectively avoids lead wire connection errors, prevents lead wires from being twisted and knotted, and prolongs the life of the lead wires.
