[0027] A plurality of adjustment grooves 31 are provided on the heart lead bracket 3. The number of adjustment grooves 31 is 6. An electrode bracket 32 is slidably connected in each adjustment groove 31. A second male surface band 33 is fixedly stitched at the connection between the heart lead bracket 3 and the second female surface band 14, and the second male surface band 33 is movably connected to the second female surface band 14.

[0028] A first mounting groove 321 is provided through the middle of the electrode support 32. A first wire routing groove 322 is provided through the electrode support 32 above the first mounting groove 321. The first wire routing groove 322 communicates with the first mounting groove 321. Sliding grooves 323 are provided on both sides of the electrode support 32, and the sliding grooves 323 are slidably connected to both sides of the adjustment groove 31.

[0029] The second mounting groove 23 includes a second electrode card slot 231 and a second wire routing groove 232 that are provided through the limb lead strap 2. The second electrode card slot 231 is located in the middle of the limb lead strap 2, and the second wire routing groove 232 is located above the second electrode card slot 231. The second wire routing groove 232 communicates with the second electrode card slot 231.

[0030] The material of the chest lead strap 1 and the limb lead strap 2 is non-woven fabric, and a number of uniformly distributed ventilation holes are provided through their surfaces.

[0031] Working steps: First, remove the suction cups on the chest lead electrodes of the electrocardiograph and the clips on the limb lead electrodes. Fix the chest lead electrodes on the chest lead support 3 and the limb lead electrodes on the limb lead strap 2. The chest lead electrodes pass through the adjustment groove 31. Insert the chest lead wire into the first wire routing groove 322 so that the chest lead wire enters the first mounting groove 321. Pull the chest lead wire outward to tightly clamp the electrode in the first mounting groove 321. Operate in sequence to clamp all six chest lead electrodes on the chest lead support 3. Connect the second sub-face belt 33 to the second mother-face belt 14 to fix the chest lead support 3 to the chest lead strap 1. Insert the limb lead wire into the second wire routing groove 232 so that the limb lead wire enters the second electrode card slot 231. Pull the limb lead wire outward to tightly clamp the electrode in the second electrode card slot 231. Operate in sequence to clamp all four limb lead electrodes on the limb lead strap 2, completing the fixation of the electrodes.

[0032] During use, adjust the position of the electrode support 32 on the adjustment groove 31 so that the electrodes clamped in the electrode support 32 are consistent with the chest lead measurement positions of the user. Wrap the chest lead strap 1 around the user's chest, with the chest lead support 3 located in front of the user's left chest. Tighten the chest lead strap 1 and connect the first mother-face belt 11 to the first sub-face belt 12 so that the chest lead electrodes are attached to the measurement positions. Wrap the limb lead strap 2 around the user's limb measurement positions. Tighten the limb lead strap 2 and connect the third sub-face belt 21 to the third mother-face belt 22 so that the limb lead electrodes are attached to the measurement positions, completing the installation and fixation of the electrocardiogram examination lead electrodes.

[0033] It should be noted that when used by patients with different body postures, due to the differences in the spacing of the chest lead measurement positions, it is necessary to replace the chest lead support 3 with a relative size. The appearance size of the chest lead support 3 remains unchanged, but the spacing of its adjustment groove 31 is different. For example, for children, the spacing of the adjustment groove 31 is smaller.

[0034] Working principle: The cardiac lead bracket 3 fixes the cardiac lead electrodes. The cardiac lead strap 1 is tied to the chest of the user. By adjusting the position of the electrode bracket 32 in the adjustment groove 31, the position of the cardiac lead electrodes can be controlled, facilitating the operation of electrocardiogram examination. The second installation groove 23 fixes the limb lead electrodes. The limb lead strap 2 is tied to the limbs of the user to complete the fixation of the limb leads. The fixation method is simple and convenient. After use, the electrodes are removed from the limb lead strap 2 and the cardiac lead bracket 3, and the electrodes are wiped to complete the cleaning of the electrodes. The cardiac lead strap 1, the limb lead strap 2, and the cardiac lead bracket 3 are cleaned. The cleaning process is the same as that of clothes, facilitating the cleaning operation. Moreover, the cardiac lead strap 1, the limb lead strap 2, and the cardiac lead bracket 3 have simple structures, and the installation of electrocardiogram examination electrodes is simple, with low production costs. Multiple sets can be prepared as spares, which is very convenient to replace in case of emergency. The cardiac lead bracket 3 is set as a detachable structure, and cardiac lead brackets 3 with different spacings of the adjustment groove 31 are produced, which are generally adapted to the cardiac lead strap 1, facilitating the examination operation for users with different body postures. The practicality of the lead fixator is strong.
