When installing the compression hemostat, the silicone positioning frame 17 can be pressed against the inner surface of the wrist to ensure that the puncture point is located inside the silicone positioning frame 17 to locate the puncture point. The silicone positioning frame 17 is made of transparent silicone material, which is transparent and easy to observe, and has a certain degree of flexibility.
[0023] As a preferred embodiment, in this example, Figures 1 to 3 As shown, a rib 9 is provided between the top right side wall of the vertical plate 8 and the bottom right side of the support plate 1, which can improve the structural strength of the vertical plate 8 and prevent the vertical plate 8 from being bent when the screw 10 is rotated.
[0024] As a preferred embodiment, in this example, Figures 1 to 3 As shown, a circular abutment plate 16 is fixedly provided at the left end of the screw 10, and a rubber pad is fixedly provided on the left side wall of the circular abutment plate 16. The diameter of the circular abutment plate 16 is larger than the diameter of the screw 10, which can increase the contact area and improve the limiting and fixing effect of the screw 10 on the ulnar plate 6.
[0025] As a preferred embodiment, in this example, Figures 1 to 3 As shown, both the radial plate 3 and the ulnar plate 6 are provided with multiple ventilation grooves 7, which can reduce their contact area with the wrist, reduce skin pressure, and help reduce weight.
[0026] In a preferred embodiment, the guide hole is a square hole, and the rod body of the T-shaped push rod 2.1 is a square rod that matches the square hole, which can prevent the T-shaped push rod 2.1 from rotating when the U-shaped cap 2.5 is rotated.
[0027] The working principle of this embodiment: After radial artery intervention, before removing the sheath, a compression hemostat is installed on the wrist for hemostasis at the radial artery puncture site. During installation, the patient's palm faces upward, and the left end of the strap 4 is not inserted into the strip-shaped insertion hole 12 at the bottom of the radial clamp 3, leaving an opening between the bottom ends of the radial clamp 3 and the ulnar clamp 6. The radial clamp 3 and ulnar clamp 6 are then placed downward on the wrist, with the arc-shaped grooves in the middle of the radial clamp 3 and ulnar clamp 6 respectively positioned on the outer sides of the radius and ulna of the wrist for positioning. The silicone positioning frame 17 is placed against the inner surface of the wrist, ensuring that the puncture point is located inside the silicone positioning frame 17. The screw 10 is rotated to adjust the distance between the top of the radial clamp 3 and the top of the ulnar clamp 6. The strap 4... The left end of the strap 4 passes through the strip-shaped insertion hole 12 at the bottom of the T-plate 5. The top of the T-plate 5 is placed against the back of the wrist. The left end of the strap 4 passes through the strip-shaped insertion hole 12 at the bottom of the radial clamp 3 from right to left and is then folded back. The strap 4 is tightened to ensure that the radial clamp 3 and the ulnar clamp 6 clamp the wrist from both sides. The Velcro nap 13 and the Velcro hook 14 on the strap 4 are glued together for fixation. After pulling out the sheath, the U-shaped cap 2.5 is quickly rotated downward to push the T-shaped push rod 2.1 downward to push the pad 2.3 to compress the puncture point to stop bleeding. The compression spring 2.2 is compressed. When the compression is released, the U-shaped cap 2.5 is rotated upward. Under the action of the rebound force of the compression spring 2.2, the T-shaped push rod 2.1 can be pushed upward to reset. The bandage 4 of the compression hemostat does not contact the back of the wrist, so that the bandage 4 does not compress the veins on the back of the wrist. Under the limiting action of the radial plate 3 and the ulnar plate 6, the compression hemostat is not easy to rotate around the wrist axis, making the installation structure of the compression hemostat more stable, ensuring the reliability of the support plate 1, and avoiding displacement of the compression hemostat mechanism 2, which would cause the puncture point compression to fail.
[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
