AI Technical Summary
Existing hemostasis devices after radial artery puncture cannot effectively fix the patient's wrist joint, causing the compression position to shift and affecting the hemostasis effect.
A radial artery compression device including a support plate and a fixing mechanism was designed. The compression mechanism and the fixing mechanism are installed on the support plate. Through the cooperation of the support plate and the fixing plate, the wrist joint is fixed by the limiting plate and the screw system to ensure that the wrist joint does not rotate during the compression hemostasis process.
It effectively stabilizes the wrist joint, prevents pressure displacement, improves hemostasis, and reduces the risk of bleeding.
