In normal people, the bleeding time is 3 min, and the coagulation time is 3 to 5 min. For patients with delayed heparin and coagulation function, the compression diverticulum should be appropriately extended for 15 min. The conventional pressing method of the cotton swab causes the pressing area to be small, the unevenness of the force to be uneven, the unstable pressing process, and the shifting of the cotton swab to cause adverse events such as skin bleeding and subcutaneous bleeding. After venous blood collection, effective compression and hemostasis should be achieved, and the pressing force needs to be even and moderate. If the strength is too small, the effect of stopping the bleeding will not be achieved. If the force is too large, the patient will be painful.
