[0033] In this embodiment, when in use, the patch mechanism 2 is first inserted into the accommodating cavity from the bottom of the cover body 1, so that the conductive post 203 on the top of the patch mechanism 2 passes through the cover body 1 and contacts the base 401, and then the ECG lead wire connector is connected to the quick connection mechanism. Then the medical staff picks up the cover body 1 and attaches the electrode assembly to the human body.

[0034] Since the patch mechanism 2 is not directly connected to the ECG lead wire connector, but is indirectly connected through the ECG lead wire connector connecting mechanism 4, when the ECG lead wire is pulled, the patch mechanism 2 is not subjected to direct pulling force, or in other words, the contact surface between the patch mechanism 2 and the human body will not undergo a large deformation, and it is not easy to separate from the human body, thereby ensuring that the patch mechanism 2 can maintain good contact with the human body, ensuring that the ECG detection can be carried out smoothly and stably, which is beneficial to ensuring the continuity and stability of ECG monitoring and ensuring the inspection effect.

[0035] In addition, since the ECG lead wire connector is installed on the sphere 402 through a quick connection mechanism, and the sphere 402 can rotate freely in the base 401, when the ECG lead wire is twisted, the ECG lead wire will drive the sphere 402 to rotate freely, thereby alleviating the twisting force caused by the twisting of the ECG lead wire and ensuring the fit between the patch mechanism 2 and the human body.

[0036] Preferably, Figure 2 and Figure 3 As shown, the cover 1 is in the shape of a round cover, the upper surface of the patch mechanism 2 is attached to the accommodating cavity at the bottom of the cover 1, and a hole for the conductive post 203 to pass through is opened at the top of the cover 1, and the conductive post 203 at the top of the patch mechanism 2 can pass through the hole at the top of the cover 1 and connect to the base 401. It should be noted that the base 401, the sphere 402 and the conductive post 203 are all made of conductive materials, such as copper.

[0037] Furthermore, a groove is provided on the lower surface of the base 401 , a needle holder is installed in the groove, and the conductive pile 203 is a connection pin, which is inserted into the needle holder in the base 401 to achieve electrical connection between the patch mechanism 2 and the base 401 .

[0047] The upper surface of the inner lining 202 of the patch mechanism 2 enters into the accommodating cavity of the cover body 1 and contacts the electric heating film 5, while the outer lining 201 does not enter into the accommodating cavity as a whole.

[0048] Preferably, Figure 2 and Figure 3 As shown, the electrode sheet for the electrocardiograph also includes a bolt member 6 and a nut member 7. Both the bolt member 6 and the nut member 7 are plastic parts, wherein a circular hole for the bolt member 6 to pass through is opened at the center of the cover body 1, and a disc is provided at the bottom of the bolt member 6, and the thickness of the disc is less than the depth of the countersunk hole in the outer lining 201.
