Description

Technical Field

[0001] This utility model relates to the field of electrocardiogram (ECG) lead wire technology, specifically to a winding control structure for ECG lead wires. Background Technology

[0002] ECG leads can become excessively long during use, requiring a winding mechanism for winding. Traditional winding mechanisms are prone to loosening at both ends during winding, and since both ends of the ECG lead are connected, the connecting ends can easily be torn apart during winding.
