[0002] The existing hemostasis technology after venous blood sampling and puncture mainly uses cotton swabs, cotton balls or infusion patches, etc., which require patients to press with their fingers for a certain period of time to stop bleeding, that is, after blood sampling or infusion, patients generally need to press the puncture site with their other hand. Due to many reasons such as patients' lack of medical knowledge, hasty explanations by medical staff, incorrect compression methods, displacement of compression points after activities, insufficient compression pressure due to lack of physical strength, and insufficient compression time, serious problems such as large-scale subcutaneous bleeding, bruising, and even infection occur. At present, in the medical industry, compression hemostasis is often involved. After searching, other hemostats are used for specific arteries, so some hemostats with different structures have also appeared.
[0003] Existing hemostats are usually used by patients themselves or by medical staff to stop bleeding, but they usually lack buffer devices and reset devices. When patients themselves or inexperienced medical staff use them to stop bleeding, they often fail to control the strength well, resulting in redness and swelling after hemostasis, causing unnecessary injuries.

The front and rear inner walls inside the sleeve 15 are provided with a limiting groove 14, and the bottom ends of the two limiting grooves 14 are fixedly connected to a No. 1 spring 4, and the upper ends of the two No. 1 springs 4 are fixedly connected to a limiting plate 13, and the two limiting plates 13 are slidably connected to the inside of the limiting groove 14, and the two limiting plates 13 are located at the opposite surfaces of one end of the outer wall of the limiting groove 14 and are fixedly connected to a push rod 1, and the push rod 1 is slidably sleeved in the inner wall of the sleeve 15, and the upper end of the push rod 1 is fixedly connected to a circular connecting block 2, and the lower end of the push rod 1 slides through the lower surface of the sleeve 15 and slides through the lower surface of the pressure plate 17, and the push rod 1 is located at the pressure plate 17. One end of the lower side of the lower surface of the plate 17 is fixedly connected to a gasket 5, and the lower surface of the pressure plate 17 away from the front and rear sides of the push rod 1 are fixedly connected to a No. 2 spring 12, and the lower ends of the two No. 2 springs 12 are fixedly connected to the No. 2 support plate 7, and the lower surface of the gasket 5 fits with the upper surface of the No. 2 support plate 7, and the lower surface of the No. 2 support plate 7 is fixedly connected to two connecting columns 8 correspondingly arranged in the front and rear, and the lower ends of the two connecting columns 8 are fixedly connected to a rubber compression plate 16, and the lower surface of the rubber compression plate 16 is fixedly connected to a sterile skin patch 9, and a protective sheet is pasted on the lower surface of the sterile skin patch 9, and the front and rear ends of the pressure plate 17 are fixedly connected to a buckle 6, and the two buckles 6 are correspondingly arranged in the front and rear, and the inner walls of the two buckles 6 are fixedly clamped with circular snap rings 11, and the two circular snap rings 11 can be detached and clamped in the inner walls of the two buckles 6 at will, and the lower surfaces of the two circular snap rings 11 are fixedly connected with elastic bands 10.
[0031] When using the hemostat, in the initial state, the circular clamping ring 11 on the front side is detached from the inner wall of the buckle 6, the protective sheet is torn off from the lower surface of the sterile skin patch 9, the sterile skin patch 9 is pressed against the bleeding skin, and then the circular clamping ring 11 detached from the buckle 6 drives the elastic band 10 to bypass the bleeding arm or other parts, so that it is fixed in the inner wall of the detached buckle 6, and the pressure plate 17 is fixed as a whole to the part that needs to stop bleeding through the elastic band 10. The medical staff places the index finger and middle finger on the lower surface of the two support plates 3 respectively, and places the thumb on the upper surface of the circular connecting block 2, and then pushes the circular connecting block 2 with the thumb to drive the push rod 1 to move downward, and the push rod 1 drives the two limit plates 13 and the two No. 1 springs 4 to move downward through the two limit grooves 14. The two limit plates 13 and the two limit grooves 14 assist and guide the movement of the push rod 1.

In the case of preliminary hemostasis, the hemostat can be quickly fixed to the bleeding part. The medical staff places the index finger and middle finger on the lower surface of the two support plates 3 respectively, places the thumb on the upper surface of the circular connecting block 2, and then pushes the circular connecting block 2 with the thumb to drive the push rod 1 to move downward, and the push rod 1 drives the two limit plates 13 and the two one The No. 1 spring 4 moves downward through the two limit grooves 14, and the two limit plates 13 and the two limit grooves 14 assist and guide the movement of the push rod 1. At the same time, the two No. 1 springs 4 can relieve the downward pressure of the push rod 1, so that the medical staff can better grasp their own hemostasis strength, thereby improving the safety of the device. The push rod 1 pushes the gasket 5 to contact the upper surface of the No. 2 support plate 7, pushing the No. 2 support plate 7 to move downward as a whole, and at the same time drives the two No. 2 springs 12 to move downward. The two No. 2 springs 12 also play a buffering role on the No. 2 support plate 7 as a whole. At the same time, when the medical staff's thumb is separated from the circular connecting block 2, the two No. 2 springs 12 are reset to drive the No. 2 support plate 7 to move upward, and drive the push rod 1 to move upward, so that it can automatically reset, which is convenient for next use and improves the practicality of the device.
