1. Before using the hemostatic patch, first check if there is any dirt left in the wound. If there is any unclean material, clean the wound with disinfected physiological saline first, and then apply the hemostatic patch. If the wound is pierced deeply by iron nails or other objects, immediate medical treatment should be sought and tetanus antitoxin injections should be administered.
2. After opening the hemostatic patch, avoid contaminating the medication surface. When applying the patch, the medication surface must be aligned with the wound. After applying the patch, apply slight pressure on both sides of the wound, and the bandage should not be too tight to prevent the wound from becoming less breathable and worsening the wound infection.
