[0002] In clinical practice, different lead wires are used in conjunction with different ECG testing equipment to detect different heart diseases in patients. Commonly used testing equipment includes conventional 12-lead ECG machines, 18-lead ECG machines, ECG analysis systems, and stereo electrocardiographs. As the number of leads used increases, the entanglement problem becomes more and more serious. Wire clamps are generally used to help straighten out the lead wires.

The anti-winding ECG lead wire set is provided with an anti-winding shell. When the first group of lead wires and the third group of lead wires are long, the manual rod is first rotated to rotate inside the fixed plate through the bearing, and then the manual rod is rotated to drive the two moving blocks to move away from the thread, so that the other end of the moving block slides outside the fixed rod, effectively realizing the linear motion of the moving block, the movement of the moving block drives the connecting rod to move so that the anti-winding outer side moves and drives the first anti-winding wire sleeve to move, and the first anti-winding wire sleeve effectively separates the first group of lead wires and the third group of lead wires into single wires, and the anti-winding shell and the fixed sleeve are provided to effectively increase the separation area of ​​the first group of lead wires and the third group of lead wires. However, the anti-winding housing and the auxiliary housing are both closed-loop, and placing the first lead wire set and the second lead wire set inside the anti-winding housing and the auxiliary housing is a problem.
