Background technique

The electrocardiograph can automatically record the bioelectric signal (ECG signal) generated by the cardiac activity when the heart is active. It is a medical electronic instrument commonly used in clinical diagnosis and scientific research. During the periodic beating of the heart, the cardiomyocytes are excited and generate a weak current locally, which is conducted to various parts of the body through the human tissue. Therefore, different potential activity changes can be collected in various parts of the human body surface. The relationship between the body surface potential and time generated by the electrical activity of the human heart is called an electrocardiogram, and an electrocardiograph records these changes. Instruments for physiological electrical signals.

At present, ECG is mainly used to record the electrical activity of the normal human heart, help diagnose arrhythmias, help diagnose myocardial ischemia, myocardial infarction and lesions, diagnose cardiac enlargement and hypertrophy, determine the impact of drugs or electrolytes on the heart, and determine artificial Cardiac pacing status, etc. In the whole process of ECG examination, the connection of lead wires is the most critical part. Due to the large number of lead wires and long lengths of current ECG machines, lead wires are often tangled during the inspection process and during storage and backup. Knotted and difficult to straighten out, it brings great inconvenience and trouble to the use of clinical medical staff. Every time an ECG machine is used to perform an ECG examination for a patient, it takes a long time for the medical staff to straighten out the entangled and knotted lead wires of the ECG machine, which greatly reduces the efficiency of the ECG examination and even leads to a delay in the examination and diagnosis of the patient's condition. .
