[0002] Large-scale medical interventional surgeries, especially those in cardiology, are performed through the patient's radial artery access. During the operation, the radial artery needs to be punctured and cannulated to monitor the body's continuous arterial blood pressure. After the arterial puncture catheter is removed at the end of the operation, arterial hemostasis is performed. Interventional surgeries with radial artery access have the advantages of fewer complications, shorter bed rest and activity restriction time, and low treatment costs.

[0003] When stopping bleeding from the radial artery, manual compression or elastic bandage is generally used to stop bleeding. The time and pressure of manual compression are not easy to control, and the operator is easily affected by fatigue. The elastic bandage pressure hemostasis covers a wide area and cannot achieve precise hemostasis at the target location. At the same time, pressing too hard will affect the blood circulation of the limbs, and pressing too lightly will not have a good hemostasis effect, affecting the actual use effect.

[0021] A threaded through hole is arranged inside the rotating ring 2, and a thread is arranged outside the lifting column 5. The rotating ring 2 is threadedly connected to the outside of the lifting column 5 through the threaded through hole. A circular through hole for placing the pressing column 2 11 is arranged at the bottom of the lifting column 5. The lifting column 5 can be lifted and lowered inside the sleeve 3 by rotating the rotating ring 2, and the lifting and lowering stability is ensured under the limiting action of the limiting strip 4 and the limiting groove 6. The outer diameter of the limiting strip 4 is matched with the inner diameter of the limiting groove 6, and the limiting strip 4 is slidably connected with the pressing column 2 11. The pointer 7 is slidably connected inside the rectangular groove 8, and the position of the scale line 9 corresponds to the pointer 7. The lifting column 5 will drive the pointer 7 to rise and fall synchronously during the lifting process. The position of the pointer 7 on the scale line 9 can timely reflect the degree of descent of the lifting column 5, that is, the pressing strength of the hemostatic device, so as to make the pressing strength of the hemostatic device intuitive. The pressing column 10 is located at the center of the lifting column 5. The center of the pressing column 2 11 is provided with a circular through hole for placing the pressing column 10. The pressing column 2 11 is sleeved on the outside of the pressing column 10. The upper surface of the pressing column 2 11 is provided with a threaded hole.

When the pressing column 11 moves upward, only the bottom surface of the pressing column 10 is pressed. When the pressing column 11 moves downward to be flush with the pressing column 10, the area of ​​hemostasis pressing is the bottom surface of the pressing column 10 and the pressing column 11, thereby expanding the area of ​​hemostasis pressing.

[0022] Working principle: when in use, the staff fixes the rotating ring 2 at the patient's hemostasis position through the cooperation of the strap 16 and the buckle 15, and then rotates the rotating ring 2 to make the lifting column 5 move downward in cooperation with the threaded hole, and uses the limit strip 4 and the limit groove 6 to make the lifting and lowering of the lifting column 5 more stable until the lifting column 5 is fitted with the hemostasis position. During the downward movement of the lifting column 5, the rectangular groove 8 will be driven to move downward synchronously. By observing the position where the rectangular groove 8 points to the scale line 9, the compression strength of the lifting column 5 can be understood, thereby visualizing the hemostasis strength, and by rotating the threaded rod 14, the pressing column 2 11 is lifted and lowered. After the threaded rod 14 is moved upward, only the bottom surface of the pressing column 10 is compressed to stop bleeding, thereby realizing the adjustment of the hemostasis area.
