[0002] In the hemodialysis process, the use of hemostatic bandage is to ensure the hemostatic effect of arteriovenous fistula puncture point, so as to protect the vascular access and reduce the occurrence of complications. Specifically, since hemodialysis usually uses a larger diameter puncture needle (such as 16G or 17G), and uses anticoagulants during dialysis, the blood vessel pressure is large, and repeated puncture can easily cause bleeding. Therefore, after dialysis, the puncture site needs to be properly compressed to stop bleeding to prevent bleeding or hematoma. Moreover, arteriovenous fistula is an important vascular access for hemodialysis patients, and the integrity of its function is crucial for dialysis treatment.

[0024] The top of the gasket 12 is provided with a compression auxiliary mechanism, which includes a second spring 11. The top of the gasket 12 is fixedly connected to the bottom of the second spring 11, and the top of the second spring 11 is fixedly connected to the inner wall of the compression block 1.
