DETAILED DESCRIPTION

[0021] Refer to the instruction manual Figures 1 to 5 The utility model provides a hemostatic clip for radial artery after coronary angiography, comprising a hemostatic clip body 1, wherein the hemostatic clip body 1 is provided with a hemostatic component for hemostasis of radial artery after coronary angiography.

[0022] like Figure 1 , 3 As shown in , 4 and 5, the hemostasis assembly includes a hollow tube 2, a positioning plate 3 is provided inside the hollow tube 2, a movable column 4 is installed at the bottom of the positioning plate 3, the bottom end of the movable column 4 passes through the hollow tube 2 and extends to the bottom of the hollow tube 2, a pressure pad 5 is installed at the bottom end of the movable column 4, a spring 6 is provided on the top of the pressure pad 5, and the spring 6 is sleeved on the outside of the movable column 4. An adjustment ring 7 is threadedly connected to the outside of the bottom end of the hollow tube 2, a pressure ring 8 is installed at the bottom end of the adjustment ring 7, the pressure ring 8 is sleeved on the outside of the top end of the movable column 4, and the pressure ring 8 is arranged on the top of the spring 6.

[0023] like Figure 1 and 2As shown, the hemostatic clamp body 1 includes an upper clamp 111, a lower clamp 112, a central axis 113 and a coil spring 114. The upper clamp 111 is arranged on the top of the lower clamp 112. The upper clamp 111 and the lower clamp 112 are connected by the central axis 113. The coil spring 114 is installed outside the central axis 113. The hollow tube 2 is arranged on the top of the upper clamp 111, and the pressure pad 5 is arranged at the bottom of the front end of the upper clamp 111. The upper clamp 111 and the lower clamp 112 can be driven to rotate with the central axis 113 by the rebound force of the coil spring 114, so that it is convenient for medical staff to operate the hemostatic clamp body 1 to stop bleeding on the radial artery of the patient. A through hole 9 is penetrated inside the front end of the upper clamping plate 111, and the movable column 4 is arranged inside the through hole 9. The outer diameters of the adjusting ring 7 and the pressing ring 8 are equal to the diameter of the through hole 9. The setting of the through hole 9 can facilitate the up and down movement of the movable column 4; and the outer diameters of the adjusting ring 7 and the pressing ring 8 are set to be equal to the diameter of the through hole 9, so that the adjusting ring 7 and the pressing ring 8 can also move at the through hole 9.

[0024] like Figure 1 , 3 As shown in , 4 and 5, the top of the adjusting ring 7 is covered with an anti-skid sleeve 10. The anti-skid sleeve 10 can enhance the friction between the medical staff's hand and the adjusting ring 7, ensure the stability of the medical staff's operation of the adjusting ring 7, and avoid loosening. The top of the hollow tube 2 is covered with a mounting ring 11, and mounting brackets 12 are installed on both sides of the mounting ring 11. The bottom end of the mounting bracket 12 is fixed to the top of the upper clamping plate 111; the mounting ring 11 and the two mounting brackets 12 can support and fix the hollow tube 2 to ensure the stability of the hollow tube 2.

[0025] like Figures 3 to 5 As shown, the diameter of the positioning plate 3 is larger than the diameter of the movable column 4. By setting the diameter of the positioning plate 3 to be larger than the diameter of the movable column 4, the positioning plate 3 can limit the movement of the movable column 4 to prevent the movable column 4 from being separated from the hollow tube 2. The inner diameter of the pressure ring 8 is equal to the diameter of the movable column 4, and the top of the spring 6 contacts the bottom of the pressure ring 8. By setting the inner diameter of the pressure ring 8 to be equal to the diameter of the movable column 4, the pressure ring 8 can squeeze and adjust the spring 6.

[0026] like Figure 1 and Figure 2 As shown, a bottom pad 13 is installed at the top of the front end of the lower splint 112, and the bottom pad 13 corresponds to the position of the pressure pad 5 up and down; through the setting of the bottom pad 13, the clamping force of the lower splint 112 on the patient's wrist can be reduced, thereby improving the comfort of the patient when using it.

[0027] When the post-coronary angiography radial artery hemostatic clamp is used, the medical staff presses the upper splint 111 and the lower splint 112, clamps the utility model from the side of the patient's wrist, and makes the pressure pad 5 contact the patient's radial artery to press and stop bleeding. The elasticity of the spring 6 allows the spring 6 to relieve the impact of the upper splint 111 when it is pressed down, so as to avoid discomfort to the patient caused by excessive pressure. At the same time, with the help of the threaded connection between the adjusting ring 7 and the hollow tube 2, the medical staff can rotate the adjusting ring 7 to drive the pressure ring 8 to move downward to compress the spring 6, and then adjust the rebound strength of the spring 6, so that the medical staff can adjust the pressure of the upper splint 111 according to the patient's needs.
