[0002] In clinical work in hospitals, electrocardiographs are often used to perform electrocardiographs to test various functional indicators of the patient's heart and determine the patient's pathological state. Since there are many lead wires on the electrocardiograph, it is easy to cause the lead wires to be entangled, which affects the inspection and normal operation of the electrocardiograph. Therefore, most of the existing electrocardiograph lead wires are provided with anti-entanglement structures. However, the existing anti-entanglement structures still have some problems during use.

[0003] For example, the Chinese patent with publication number CN217014067U discloses an anti-winding device for an electrocardiograph, including a base and a cover plate, wherein the base is provided with a plurality of lower concave holes, and the cover plate is provided with upper concave holes corresponding to the lower concave holes, and the lower concave holes and the upper concave holes are matched to form a through hole for accommodating lead wires; the cover plate is provided with a slide groove, and the base and the cover plate are provided with a plug hole, and the plug hole and the slide groove are connected; a plug rod is slidably connected in the plug hole, and a lifting plate is connected to the top of the plug rod, and the lifting plate is slidably connected to the slide groove; a positioning hole is provided on the rod wall of the plug rod, and a positioning pin is movably connected to the side wall of the base, and the positioning pin is adapted to the positioning hole. The utility model has a simple structure and is easy to operate. When the base and the cover plate are matched, the upper concave hole and the lower concave hole are matched to form a through hole for accommodating lead wires; each through hole corresponds to a lead wire, and the lead wires can be arranged in an orderly manner, which can effectively prevent the lead wires from winding and knotting, and can be used in practice.

[0004] The above-mentioned device uses a snap-fit ​​structure to fix and position multiple lead wires, and can only position part of the lead wires. Since most of the lead wires are long, they will still be entangled in other positions, affecting their use. Therefore, the present application provides an anti-entanglement device for electrocardiograph lead wires to meet the needs. Utility Model Content

[0022] Example 1: Reference Figure 1-3The electrocardiograph lead wire anti-winding device shown comprises a mounting seat 1, on which a positioning unit for arranging and fixing a plurality of lead wires is arranged, the positioning unit comprises a plurality of first arc portions 2 opened on the mounting seat 1, the lead wires are clamped on the first arc portions 2, a plurality of balls 3 are arranged on the first arc portions 2, so that the lead wires can slide on the first arc portions 2 through the balls 3, and the plurality of first arc portions 2 are arranged to arrange and fix the plurality of lead wires, and at the same time, the balls 3 are arranged to allow the lead wires to slide on the first arc portions 2, so that the position can be quickly adjusted, thereby improving the anti-winding effect.

[0023] The mounting seat 1 is provided with a limiting unit for fixing a plurality of lead wires, the limiting unit comprises a connecting rod 4 slidably connected to the mounting seat 1, a plurality of second arc portions 5 are provided on the connecting rod 4, the bottom end of each second arc portion 5 is fixedly connected to a first stopper 6, a third arc portion 15 is provided on each first stopper 6, an opening portion 7 is provided between two adjacent first stoppers 6, each first arc portion 2, the second arc portion 5 and the third arc portion 15 are combined to form a circular hole structure adapted to the outer diameter of the lead wire, and when in use, the first stopper 6 is pushed to move so that The first stopper 6 is misaligned with the first arc portion 2. At this time, the opening portion 7 corresponds to the first arc portion 2. Then, multiple lead wires are clamped onto the first arc portion 2 through the opening portion 7. Then, the first stopper 6 is pushed in the reverse direction to drive the connecting rod 4 to move, so that the second arc portion 5 on the connecting rod 4, the third arc portion 15 on the first stopper 6 and the first arc portion 2 form a circular hole structure, which just wraps the lead wire to form a fixed limiting structure. The second arc portion 5 and the third arc portion 15 are both provided with an anti-slip layer to prevent the lead wire from sliding in the first arc portion 2 to provide a positioning effect.

[0024] A first spring 8 is provided in the mounting seat 1, and one end of the first spring 8 is fixedly connected to the connecting rod 4. A slider 9 is fixedly connected to one side of the top end of the mounting seat 1, and a slide groove 10 adapted to the slider 9 is provided on one of the first stoppers 6. When the first stopper 6 is pushed to move so that the opening 7 is aligned with the first arc portion 2, the first spring 8 is stretched by force. After the lead wire is clamped in the first arc portion 2, the first stopper 6 can be released and automatically reset with the cooperation of the first spring 8, thereby improving the installation convenience and the stability of use. At the same time, during the sliding process of the first stopper 6, the cooperation and guidance of the slider 9 and the slide groove 10 further improves the stability of use.

The top end of the second spring 14 is fixedly connected to the same second block 13, and the top end of the second block 13 conflicts with the slide rail 12. Before pushing the first block 6 to move, the first spring 8 is replaced, so that when the first arc portion 2, the second arc portion 5 and the third arc portion 15 stably clamp the lead wire, the first spring 8 is in a compressed state at this time. When in use, the push block 11 is first pushed downward to drive the second spring 14 to move downward. The second stopper 13 is separated from the slide rail 12, and with the cooperation of the compressed first spring 8, the connecting rod 4 is pushed to move automatically, thereby moving the first stopper 6, so that the opening portion 7 moves to align with the first arc portion 2. At this time, the lead wire can be placed on the first arc portion 2, and then the first stopper 6 is pushed in the opposite direction to drive the first spring 8 to return to the compressed state, and at the same time drive the slide rail 12 to move, until the second stopper 13 is pushed to be connected to the end of the slide rail 12 under the action of the second spring 14, and the push block 11 is pushed to reset upward. At this time, the second arc portion 5 and the third arc portion 15 move to cooperate with the first arc portion 2 to form a stable clamping state for the lead wire, thereby improving the clamping stability and the convenience of disassembly and assembly, and having high practicality.
