[0001] This utility model relates to the field of electrocardiographs, specifically an anti-tangling mechanism for electrocardiogram circuits. Background Technology
[0002] Electrocardiogram (ECG) machines automatically record the bioelectrical signals generated by myocardial excitation during cardiac activity, making them commonly used medical electronic instruments for clinical diagnosis and scientific research.

[0025] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0026] This application discloses an anti-tangling mechanism for electrocardiogram (ECG) circuits. (Refer to...) Figure 1 An anti-tangling mechanism for electrocardiogram (ECG) lines includes an ECG machine 1, a lead wire 2 inserted into the right side of the ECG machine 1, and a storage tray 31 inserted into the left side of the ECG machine 1. Slots are provided on both the front and rear sides of the left end face of the ECG machine 1. Protrusions that are compatible with and engage with the slots are fixedly installed on the surface of the storage tray 31, allowing the storage tray 31 to be installed in the corresponding position on the ECG machine 1 for easy storage. A cylindrical groove 32 is provided at the top of the storage tray 31, and a storage cavity 33 is provided inside the storage tray 31. A guide component 4 is provided inside the storage tray 31, and a winding component 5 is provided at the bottom of the guide component 4.
[0027] Reference Figure 2 - Figure 5The guide assembly 4 includes a fixed post 41 fixedly installed inside the cylindrical groove 32. The cylindrical groove 32 and the storage cavity 33 are connected. The bottom end of the fixed post 41 is fixedly connected to the inner wall of the cylindrical groove 32 through a straight rod. The straight rods are evenly spaced at the bottom of the fixed post 41. A U-shaped block 42 is fixedly connected to the surface of the fixed post 41. The storage tray 31 is located on the inner wall of the cylindrical groove 32 and has an inner groove 431. An annular groove 432 is formed inside the storage tray 31. A battery 433 is snapped into the inner groove 431. The storage tray 31 is located on the inner wall of the cylindrical groove 32. A control switch 434 is fixedly connected to the inner wall of the cylindrical groove 32. A wire 435 is electrically connected to the surface of the battery 433. A locking block 441 is snapped into the inside of the inner groove 431. An electromagnet 442 is fixedly connected inside the locking block 441. The inner groove 431 and the annular groove 432 are connected. The battery 433 and the electromagnet 442 are electrically connected. The control switch 434 is electrically connected to the battery 433. The control switch 434 can control whether the battery 433 supplies power to the electromagnet 442. The end of the locking block 441 away from the inner wall of the storage tray 31 is... A guide rod 443 is fixedly connected. A sliding rod 451 is slidably connected inside the U-shaped block 42 near the inner groove 431. An arc-shaped limiting plate 452 is fixedly connected to the end of the sliding rod 451 away from the electromagnet 442. A hollow block 453 is fixedly connected to the end of the sliding rod 451 away from the arc-shaped limiting plate 452. A return spring 454 is wound around the surface of the sliding rod 451. A magnet 455 is fixedly connected inside the hollow block 453 at the end away from the sliding rod 451. The interior of the U-shaped block 42 on the side away from the electromagnet 442 is open. A groove 456 is provided, and an arc-shaped limiting plate 452 is located inside the groove 456. The two ends of the return spring 454 are fixedly connected to the near ends of the U-shaped block 42 and the hollow block 453, respectively. When the sliding rod 451 slides inside the U-shaped block 42, it will cause the return spring 454 to change its elastic force. The near ends of the magnet 455 and the electromagnet 442 are the same magnetic poles. When the electromagnet 442 is energized, it will repel the magnet 455. At this time, the magnet 455 will drive the arc-shaped limiting plate 452 to move to the outside of the groove 456 through the sliding rod 451.
[0028] Reference Figure 3 and Figure 6 The winding assembly 5 includes a bottom groove 51 formed inside the bottom end of the fixed post 41. A motor 52 is fixedly installed on the top wall of the bottom groove 51. A winding rod 53 is rotatably connected inside the bottom groove 51. A bent rod 54 is fixedly connected to the surface of the winding rod 53. The output shaft at the bottom end of the motor 52 is fixedly connected to the top end of the winding rod 53. Both the upper and lower ends of the bent rod 54 are adapted to and in contact with the winding rod 53, which can drive the motor 52 to drive the winding rod 53 to rotate inside the fixed post 41. A guide ring 55 is fixedly connected to the top surface of the winding rod 53.
[0029] Working principle: The operator first removes a storage tray 31 and places it in a suitable position on the bed. Then, the lead wire 2 is passed between the winding rod 53 and the bent rod 54 on the side away from the electrocardiograph 1, and then through the guide ring 55. Finally, multiple lead wires 2 are passed through each U-shaped block 42 in sequence and connected to the corresponding parts of the patient. At this time, the tightness of the lead wire 2 between the patient and the U-shaped block 42 can be adjusted appropriately to avoid the lead wire 2 being too tight and causing discomfort to the patient.
[0030] At this time, the medical staff presses the control switch 434, which drives the electrically connected battery 433 to supply power to the electromagnet 442. When the electromagnet 442 is energized, it will repel the magnet 455, causing the magnet 455 to push the sliding rod 451 to compress the return spring 454 and move away from the electromagnet 442. Since the hollow block 453 is provided with a guide rod 443 on its outer surface, the hollow block 453 moves relatively smoothly. Therefore, the sliding rod 451 will push the arc-shaped limiting plate 452 to move to the outside of the groove 456. At this time, the arc-shaped limiting plate 452 will limit the connecting wire 2 passing through the U-shaped block 42 to the surface of the fixing post 41, thereby limiting the part of the connecting wire 2 located inside the U-shaped block 42. At this time, the separate connecting wires 2 will not get close and entangle.
[0031] Then, the drive motor 52 drives the winding rod 53 to rotate inside the bottom groove 51. When the winding rod 53 rotates, the guide ring 55 will rotate with it. At this time, the tilt angle between the guide wire 2 inside the guide ring 55 and the winding rod 53 remains relatively constant. Then, when the winding rod 53 rotates, it will wind the guide wire 2 below the guide ring 55, so that the guide wire 2 is wound on the surface of the winding rod 53. However, due to the limitation of the bent rod 54, the guide wire 2 is prevented from detaching from the winding rod 53 until a longer part of the guide wire 2 is wound on the surface of the winding rod 53 and located inside the storage cavity 33.
[0032] In this way, the lead wires 2 corresponding to the limbs and chest cavity are organized by multiple storage trays 31, thus avoiding the situation where the lead wires 2 corresponding to the limbs and chest cavity are tangled together due to their length.
[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
