Description

[0001] The utility model relates to the technical field of medical care, in particular to a radial artery compression tourniquet. Background Art

[0002] The hemostasis of radial artery after puncture is mostly achieved by manual finger pressure or soft cuff and bandage. This method has poor controllability, and too little pressure can easily lead to bleeding, while too much pressure can easily cause radial artery occlusion, local skin and nerve damage, and requires high experience of medical personnel. For this reason, radial artery compression tourniquets have been gradually developed and used clinically. At present, there are some radial artery hemostat on the market, for example: the base plate and the pressing platform of a radial artery compression hemostat are made of transparent plastic material, and the pressure is adjusted by adjusting the tightness of the wristband.
