[0003] Electrocardiogram (ECG) monitoring is a common, non-invasive method for monitoring cardiac electrical activity. In intensive care units, it is primarily used to monitor patients' vital signs in real time, enabling timely detection and intervention of sudden changes in their condition. Because critically ill patients have complex and variable conditions, and may experience serious situations such as arrhythmias or cardiac arrest at any time, ECG monitoring provides crucial information for resuscitation.

[0004] Existing electrocardiogram (ECG) monitoring technologies utilize electrodes and colored leads in ECG monitors for monitoring, but the electrodes are prone to detaching from the leads due to external force, affecting monitoring efficiency and making them inconvenient to use. Therefore, a portable electrode holder for ECG monitoring is proposed to solve the above problems. Utility Model Content

A neck loop 4 is provided on the upper surface of the fixator body 1 for the patient to wear. The neck loop 4 on the fixator body 1, combined with the elastic fabric sheet 2 and the adhesive patch 3 with Velcro, facilitates customization according to the patient's needs. The device is designed to fit the patient's actual body shape, allowing the main body 1 to be worn over the external electrode patches. Multiple electrode fixing components 5 are arranged on the outer surface of the main body 1 according to the ECG monitoring points. Each electrode fixing component 5 includes a threading tube 51, whose outer wall is fixedly fastened to the outer surface of the main body 1. The surface of the threading tube 51 has a rotating groove 52, and a 360° rotatable locking element 53 is movably connected inside the rotating groove 52. A fixing cylinder 54 is fixedly connected to the end of the rotating locking element 53, and a useful opening is provided on the lower surface of the fixing cylinder 54. The electrode connector is connected to the outlet slot 55. The upper surface of the fixed cylinder 54 has an L-shaped positioning groove 56. The inner wall of the fixed cylinder 54 has an adjustment groove 57 with a straight groove structure. A guide rod 58 is fixedly connected between the outer surface of the fixed cylinder 54 and the inner wall of the adjustment groove 57. A spring 59 is sleeved on the front end of the outer periphery of the guide rod 58. The outer surface of the fixed cylinder 54 has a mounting through hole, wherein the inner wall size of the mounting through hole is larger than the outer wall size of the spring 59. A pressure plate 510 is sleeved on the rear end of the outer periphery of the guide rod 58. The outer wall of the pressure plate 510 is flush with the fixed cylinder 54. The inner wall size of 4 is adapted to the plate. An adjusting plate 511 is fixedly connected to the side of the pressure plate 510 away from the guide rod 58. Multiple electrode fixing components 5 are set according to the ECG monitoring points. The electrode connector wires to be connected are connected to the electrode patches through the fixing cylinder 54 and the wire threading cylinder 51. Then, by rotating the pressure plate 510, the adjusting plate 511 is locked in the positioning groove 56. Under the extension of the spring 59, the pressure plate 510 is pushed along the adjusting groove 57 to press and fix the connection between the electrode patch and the electrode connector wires, which can effectively prevent the ECG monitoring electrodes from loosening.

[0033] Reference Figure 1 and Figure 2The outer surface of the fixation body 1 is provided with a take-up assembly 6 for storing multiple electrode wires at the ECG monitoring point. The take-up assembly 6 includes a take-up groove 61 located at the center of the outer surface of the fixation body 1. A lead wire piece 62 is fixedly connected to the outer edge of the take-up groove 61. There are two lead wire pieces 62, which are mirror images of each other along the central axis of the take-up groove 61. A rough-surface fixing patch 63 is fixedly connected to one side of the outer surface of the fixation body 1 located in the take-up groove 61, and a hook-surface fixing patch 64 is fixedly connected to the other side of the outer surface of the fixation body 1 located in the take-up groove 61. Multiple hook-face fixing patches 64 are evenly distributed along the length of the wire take-up groove 61, and multiple rough-face fixing patches 63 and hook-face fixing patches 64 are set one-to-one. A storage bag 65 is fixedly connected to the lower edge of the outer surface of the main body 1. A wire hole 66 is opened on the side of the storage bag 65. By placing the ECG dynamic monitor in the storage bag 65, the electrode connector wire to be connected is passed through the wire hole 66, and the wire is arranged and fixed in the wire take-up groove 61 with rough-face fixing patches 63 and hook-face fixing patches 64 through the electrode connector wire. This can avoid the accidental pulling and loosening of the messy dragging of the electrode wire.

[0034] Working principle: In use, the neck loop 4 on the fixation body 1, combined with the elastic and stretchable elastic fabric 2 and the adhesive patch 3 with Velcro, allows for easy wearing according to the patient's body shape. The fixation body 1 is then placed on the patient wearing the electrode patch, and the ECG dynamic monitor is placed in the storage bag 65. The required electrode connector wiring is led out through the wire hole 66. These wirings are arranged and fixed by the wire take-up groove 61 with the rough-surface fixing patch 63 and the hook-surface fixing patch 64. The fixation body 1 is provided with multiple electrode fixing components 5 for fixing and connecting the electrode connector wiring and the electrode patch. By rotating the pressure plate 510, the adjusting plate 511 is inserted into the positioning groove 56. With the extension of the spring 59, the pressure plate 510 presses and fixes the connection between the electrode patch and the electrode connector wiring along the adjusting groove 57, effectively preventing the electrodes from loosening during ECG monitoring. In addition, the soft and skin-friendly fixation body 1 is easy to fold and carry.
