AI Technical Summary
Technical Problem
Existing radial artery hemostasis devices after coronary angiography are prone to loosening or falling off due to their fastening with Velcro, resulting in low stability and safety.
Method used
The device employs a dual fixation structure for radial artery hemostasis. The double fixation of the strap is achieved through the hook at the end of the strap and the Velcro. The mechanical structure of ratchet and spring ensures a stable fit between the strap and the patient's wrist.
Benefits of technology
This improves the stability and safety of the hemostatic device, preventing accidental loosening or detachment caused by a single Velcro fastener, and ensuring effective hemostasis.

Abstract
A radial artery hemostasis device used after coronary angiography comprises a shell and a threaded rod, the inner wall of the shell is in threaded connection with the threaded rod, a radial artery hemostasis double-fixing structure is arranged on the right side of the outer wall of the shell, the lower end of the threaded rod is rotationally connected with a block through a bearing, and two sliding rods are fixedly connected to the upper end of the outer wall of the block. The outer wall of the sliding rod is in sliding connection with the shell. According to the radial artery hemostasis device used after coronary angiography, through cooperation of a radial artery hemostasis double-fixing structure and a hook-and-loop fastener, the vertical rod is pushed to abut against the ratchet wheel, a tree crown is pulled upwards to be separated from the ratchet wheel, meanwhile, the vertical rod can apply pressure to the spring, and after the arm of a patient is wound and fixed through the bandage, the arm is fixed through the hook-and-loop fastener. The bandage and the wrist of a patient can be doubly fixed through the hanging ring hooks and the hook-and-loop fasteners at the end and the tail end of the bandage, the problem that in the prior art, the bandage is fixed only through the hook-and-loop fasteners, and bleeding is caused by accidental loosening or falling off is solved, and then stability and completeness are effectively improved.
