The sliding portion 44 is in the shape of an inverted T, and the limiting portion 42 and the sliding portion 44 are connected and fixed by means of threaded bolts. The sliding portion 44 is adapted to be embedded into the internal width direction of the receiving space 211. The surface of the cover 22 is provided with a through slot 221. When the cover 22 covers the shell 21, the end of the sliding portion 44 connected to the limiting portion 42 protrudes out of the slot 221.

The limiting portion 42 is located at the end of the moving member 4 away from the compression plate 2, and the rotating shaft 3 is limited in the shell 21.
[0037] As shown in FIGS. 1 to 5, the compression plate 2 comprises a shell 21 and a cover 22, and the shell 21 is provided with a receiving space 211. The width of one end of the moving member 4 is adapted to be embedded into the internal width direction of the receiving space 211. Figure 6As shown, rotating parts 32 are fixed at both ends of the rotating shaft 3, and a knob 33 is fixed to the end of one of the rotating parts 32 of the rotating shaft 3. See also the attached diagram. Figure 5 The end faces of both ends of the housing 21 are provided with mounting grooves 212. The bottom surface of the mounting grooves 212 is recessed to form a first arc-shaped groove 213. The two ends of one side of the cover 22 are raised to form a packaging part 222. The packaging part 222 is provided with a through second arc-shaped groove 223. When installing the rotating shaft 3, the rotating shaft 3 is placed in the accommodating space 211, so that the rotating parts 32 at both ends of the rotating shaft 3 are respectively embedded in the first arc-shaped grooves 213 at both ends of the housing 21; then, each moving part 4 is placed in the accommodating space 211, and the pressing surfaces 43 of the moving parts 4 at both ends of the pressing plate 2 are mirror-oriented, and the limiting pins 41 of each moving part 4 are respectively inserted into the spiral grooves 31 of the rotating shaft 3; finally, the cover 22 is covered on the housing 21, so that the two encapsulation parts 222 at both ends of the cover 22 are respectively embedded in the two mounting grooves 212 at both ends of the housing 21, and the second arc-shaped grooves 223 at both ends of the cover 22 are respectively fitted over the rotating parts 32 at both ends of the rotating shaft 3, restricting the rotating parts 32 at both ends of the rotating shaft 3, so that the rotating parts 32 of the rotating shaft 3 are restricted to the circular through hole formed by the splicing of the first arc-shaped groove 213 and the second arc-shaped groove 223 and can only rotate, thereby restricting the rotating shaft 3 to rotate within the pressing plate 2. Alternatively, the knob 33 at the end of the rotating shaft 3 can be located outside the housing 21 so that the rotating shaft 3 can be rotated by rotating the knob 33, thereby causing the moving parts 4 at both ends of the pressure plate 2 to move synchronously.
[0038] Furthermore, as shown in the appendix Figure 3 As shown, the rotating part 32 of the fixed knob 33 is provided with an external thread, which is screwed to the nut 34. After adjusting the position of the moving part 4 by the knob 33, the knob 33 is gripped and the nut 34 is rotated until the nut 34 is tightened to the end face of the pressure plate 2, so that the end faces of the nut 34 and the rotating shaft 3 in the accommodating space 211 clamp the encapsulation part 222, thereby fixing the rotating shaft 3 relative to the pressure plate 2 and preventing the rotating shaft 3 from rotating.
[0039] Continue to refer to the appendix Figure 1 and 3 The compression band 5 is attached to the compression surface 43 of each movable component 4. The attachment method can be that one side of the compression band 5 has a hook-and-loop fastener, and each compression surface 43 is secured with adhesive to the looped side of the fastener. The compression band 5 is attached to each compression surface 43 through the adhesion of the hook-and-loop fastener and the looped side, allowing for easy removal and replacement. Additionally, the side of the compression band 5 facing away from the movable component 4 also has a protruding compression body 51. When the compression surfaces 43 at both ends of the compression plate 2 clamp the patient's legs and the strap 1 tightens the compression plate 2 at the thigh, the compression body 51 compresses the patient's femoral artery or femoral vein.
[0040] After the sheath tube is pulled out in the minimally invasive intervention treatment, the utility model is set as follows:
[0041] The binding belt 1 is passed through the connecting hole 224 of the compression plate 2 after being wound around the thigh, and then the compression main body 51 in the compression belt 5 on the surface of the compression plate 2 is corresponded to the femoral artery or femoral vein needing compression;
[0042] Then the first adhesive surface of the binding belt 1 is pulled to the binding belt 1 to paste the compression plate 2 tightly on the thigh, so that the compression main body 51 of the compression belt 5 is pressed on the puncture point of the femoral artery or femoral vein, and then the first adhesive surface 11 and the second adhesive surface 12 are adhered and fixed;
[0043] Finally, the knob 33 is rotated to drive the rotation shaft 3 to rotate, so that the moving pieces 4 on both sides of the compression plate 2 are simultaneously moved to both sides of the thigh, and the compression faces 43 at both ends of the compression plate 2 are moved to the compression belt 5 to clamp the thigh.
[0044] From the above setting mode, the elastic tightening of the binding belt 1 can press the compression belt 5 on the thigh of the patient, ensure that the compression main body 51 presses the puncture point, and the moving pieces 4 on both sides of the compression plate 2 clamp the thigh to improve the stability of the compression belt 5, avoid the rotation of the compression belt 5 around the thigh to make the compression main body 51 away from the puncture point. As can be seen, the binding belt 1 and the compression plate 2, the rotation shaft 3 and the moving piece 4 in the utility model are used to fix the compression belt 5 on the leg of the patient, and the tightness of the binding belt 1 can be adjusted to ensure that the compression belt 5 and the compression main body 51 are fixed for a long time after the operation without displacement, which is suitable for the compression hemostasis of the femoral artery or femoral vein after the minimally invasive intervention, and integrates compression, antibacterial, promotion of healing and comfort, can effectively solve the problems of hematoma and infection in the nursing after the minimally invasive intervention, and has wide clinical application value.
[0045] The above is only a specific embodiment of the utility model, but the design concept of the utility model is not limited to this, and any non-essential change of the utility model by using this concept should belong to the behavior of infringing the protection range of the utility model.
