Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0051] Reference Figures 1 to 6 The first embodiment of this utility model proposes an electrocardiogram (ECG) lead wire, which includes: a connector base 10, a fitting seat 20, a lead connector 30, a sealing component 40, and an anti-dislodgement component 50;

[0052] The connector base 10 is provided with a guide cavity;

[0053] The connector 20 is disposed on the connector base 10, and the connector 20 is used to embed into the lead interface 101 of the ECG host 100;

[0054] One end of the conductive connector 30 is inserted and fixed to the socket 20 to be disposed in the conductive cavity, and the conductive connector 30 is used to connect to the conductive interface 101 for communication.

[0055] The sealing component 40 is disposed on the connector base 10, and the sealing component 40 is used to be embedded in the key interface 102 of the ECG host 100;

[0056] The anti-detachment component 50 is movably installed on the connector base 10 and is detachably embedded in the ECG host 100.

[0057] The conductive cavity is the cavity through which the conductive connector 30 connects to the conductive wire.

[0058] The method of using the ECG lead wire of this utility model is as follows:

[0059] The user first holds the connector base 10 and aligns it with the ECG host 100, so that the insert 20 is aligned with the lead interface 101, the sealing component 40 is aligned with the key interface 102, and the anti-dislodgement component 50 is aligned with the screw connection on the ECG host 100.

[0060] Push the connector base 10 again so that the lead connector 30 is inserted into the lead interface 101;

[0061] The communication connection between the ECG host 100 and the ECG leads is completed, and the sealing component 40 is inserted into the key interface 102 to complete the sealing protection of the key interface 102, preventing dust, liquid and other contaminants from entering from the key interface 102, thus avoiding affecting the stability of the communication connection between the ECG host 100 and the ECG leads; and preventing the signals input from the power cord and other data lines plugged into the key interface 102 from affecting the communication connection between the ECG host 100 and the ECG leads when the ECG host 100 and the ECG leads are in communication.

[0062] Then rotate the anti-dislodgement component 50 to fix it on the ECG host 100, which strengthens the connection stability between the lead connector 30 and the lead interface 101, and also strengthens the connection stability between the blocking component 40 and the key interface 102, thereby ensuring the stable communication between the ECG host 100 and the ECG lead wire.

[0063] In this embodiment, the connector 20 is used to initially stabilize the connection between the lead connector 30 and the lead interface 101. The anti-dislodgement component 50 is used to further strengthen the connection stability between the lead connector 30 and the lead interface 101. The dual fixing structure reduces the dislodgement rate of the ECG lead wire, thereby enabling continuous acquisition of ECG signals even in scenarios such as patient transfer or accidental pulling, avoiding data loss due to signal interruption and improving diagnostic accuracy.

On the one hand, it prevents contaminants from adhering to the contact terminals of the lead connector 30 and the lead interface 101, preventing interference in ECG signal transmission due to poor contact and ensuring the clarity and accuracy of ECG signal acquisition. On the other hand, it eliminates the risk of short circuits caused by liquid seepage into the lead interface 101, reducing the failure rate of the lead interface 101, extending the service life of the lead interface 101 of the ECG host 100, and reducing the frequency and cost of equipment maintenance. It further improves the connection and fixation stability of the lead connector 30 and the lead interface 101, enhances the resistance to external interference, and reduces wear on the lead interface 101, extending the service life of the ECG host 100 and the ECG lead wires.

[0066] Further, based on this embodiment, refer to Figures 1 to 4 The side wall of the connector base 10 is provided with anti-slip protrusions 14 or anti-slip ridges 15, thereby increasing the friction between the user's hand and the connector base 10 and preventing slippage when pushing or pulling.
