Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of medical devices, and particularly relates to a track type chest lead device for an electrocardiograph. BACKGROUND

[0002] An electrocardiogram (ECG, full name Electrocardiogram) is a technique for recording the electrical activity of the heart from the body surface. It can accurately record the electrical activity of the heart, helping doctors to determine whether there is arrhythmia, such as tachycardia, bradycardia, atrial fibrillation, etc. The electrocardiogram can also reflect the structure and function of the heart, such as myocardial ischemia, myocardial infarction, etc. It has important significance for the early detection and treatment of heart disease.

[0003] An electrocardiogram is an important heart examination method, which has important significance for diagnosing heart disease, assessing heart health, and monitoring drug efficacy. Currently, when doing an electrocardiogram, multiple electrodes at different positions on the patient's body are needed to detect potential differences, and then the electrocardiogram of the current patient is generated. However, there are two problems in this process: one is that there are many chest lead wires and they are easy to entangle, which is very difficult to untangle after entanglement, greatly affecting efficiency, and limiting the number of patients who can have an electrocardiogram in a certain period of time; the second is that after the electrode is applied, there is no corresponding mechanism to effectively fix the electrode, which is easy to loosen and fall off during the process, resulting in failure to meet the corresponding examination requirements. To some extent, there are still defects.
