Description

Technical Field

[0002] An electrocardiogram (ECG) is a technique that uses an ECG machine to record the changes in electrical activity of the heart during each cardiac cycle from the body surface. During ECG testing, finger-type ECG electrodes are used. However, the existing finger-type ECG electrodes cannot be adjusted in length. Since the finger lengths of different people and people of different ages are different, the fixed-length finger-type ECG electrodes cannot well meet the needs of different people and are inconvenient to use.

[0003] For example, a finger-type ECG electrode with publication number CN220109742U includes a finger-type ECG electrode assembly, comprising a connecting strap, a finger sleeve fixed to one end of the connecting strap, an electrode plate fixed to the finger sleeve, an electric wire connected to the electrode plate, and a wrist strap fixed to the other end of the connecting strap. The top surface of the connecting strap has a mounting hole. The finger clamping assembly includes a first U-shaped clamp fixed to the inner wall of the mounting hole and a second U-shaped clamp disposed on the inner wall of the other side of the mounting hole, and the distance between the second U-shaped clamp and the first U-shaped clamp can be adjusted. A threaded rod is rotatably mounted on the inner wall of the first U-shaped clamp, a guide rod is fixed on the inner wall of the first U-shaped clamp, and a threaded hole that engages with the threaded rod is opened on the inner wall of the second U-shaped clamp. This technical solution also has the aforementioned technical problems. Utility Model Content

The distance between the movable block 1 and the fixed block 2 is adjustable. A middle block 23 is fixedly connected to the bottom of the fixed block 2. There are two straps 4, which are symmetrically connected to the front and rear sides of the middle block 23. Both straps 4 are connected with Velcro 19, one Velcro 19 is connected to the inside of the strap 4, and the other Velcro 19 is connected to the outside of the strap 4.

[0020] Please see Figure 1-3 A connecting block 5 is fixedly connected to the top of both the movable block 1 and the fixed block 2. The two connecting blocks 5 are connected to each other by a connecting telescopic rod 6. A wire is connected to the electrode body 3, and the wire is movably connected to both connecting blocks 5.

[0021] Please see Figure 1-3 A threaded shell 7 is rotatably connected to the right side of the movable block 1. A coarse threaded rod 8 is threadedly connected to the inner wall of the threaded shell 7. The end of the coarse threaded rod 8 away from the threaded shell 7 is fixedly connected to the fixed block 2. A connecting seat 17 is fixedly connected to the side of the movable block 1. A bearing 18 is provided in the groove on the side of the connecting seat 17. The inner wall of the inner ring of the bearing 18 is fixedly connected to the surface of the threaded shell 7, and the surface of the outer ring of the bearing 18 is fixedly connected to the connecting seat 17.

[0022] Please see Figure 1-3 A fixed shell 9 is provided below the movable block 1, and the electrode body 3 is located inside the fixed shell 9.

Pull the moving plate 11 down directly, and then insert the finger into the fixed shell 9. Release the moving plate 11. The spring 16 will drive the electrode body 3 to move downward through the moving plate 11. The electrode body 3 will press on the finger. If the finger is too thick or too thin, the initial position of the electrode body 3 in the fixed shell 9 can be adjusted. By turning the fine threaded rod 13 with the toggle block 22, the different rotation directions of the fine threaded rod 13 will cause it to move upward or downward. The fine threaded rod 13 will drive the drive plate 14 to move through the bearing 21. The drive plate 14 will drive the moving plate 11 to move through the spring 16. The stabilizing telescopic rod 20 will extend or shorten. This can adjust the initial position of the electrode body 3 inside the fixed shell 9.
