Technical Field
[0001] The utility model relates to the technical field of electrocardiogram lead wires, in particular to an electrocardiogram lead wire fixing device capable of preventing winding. Background Art
[0002] Electrocardiogram is a technology that uses an electrocardiograph to record the changes in electrical activity produced by each heart cycle from the body surface. ECG lead wires generally need to be used in conjunction with instruments such as electrocardiographs and monitors. The ECG lead wires are connected to the monitor and are generally fixed to the surgical patient through snap-type or clamp-type electrode connectors.
[0003] However, the following problems still exist in actual use:
[0004] (1) The existing fixing device cannot fix lead wires of different thicknesses when in use, resulting in the need to use different fixing devices when fixing them, which is relatively cumbersome.
[0005] (2) The fixing device cannot be adjusted during fixing, so the supporting point of the lead wire is relatively single, and thus the practicality is low. Utility Model Content

It has the function of being able to fix lead wires of different thicknesses without the need to use different fixing devices to reduce the cumbersomeness. In addition, the supporting points of the lead wires can be adjusted to increase the overall practicality of the device, thereby solving the problems raised in the background technology.

[0009] Compared with the prior art, the utility model has the following beneficial effects:
[0010] 1. The ECG lead wire fixing device capable of preventing entanglement has the advantages that after the lead wire passes through the middle of the clamping plate, if a thicker lead wire is encountered, the spring, the second support block and the third support block can jointly press the clamping plate to move closer to each other to generate an extrusion force, and the clamping plate can be adjusted in angle under the action of the sleeve, the rotating rod and the first support block.

The bottom of the supporting shell 2 is slidably connected to the top of the bottom shell 1. After the lead wire passes through the middle of the clamping plate 8, if a thicker lead wire is encountered, the spring 11, the second support block 9 and the third support block 10 can work together to press the clamping plate 8 to move closer to each other to generate an extrusion force, and the clamping plate 8 can be adjusted in angle under the action of the sleeve 7, the rotating rod 6 and the first support block 5. After the fixation is completed, the turning handle 14 is turned to drive the limiting wheel 13 to rotate, thereby driving the belt 15 to operate.
