If a wound appears on the finger to be bandaged, it depends on the size of the wound and the bleeding situation: if the wound is large and accompanied by a local skin defect, the wound must usually be covered with a Vaseline gauze block after disinfection, then a clean sterile gauze block to cover the wound and a bandage to wrap it, and after pressure bandaging, an elastic net can be used to cover the finger to fix the gauze block. In addition, if the wound is small and covered with a band-aid and the bleeding is not too much, a band-aid can be used to dress the wound, and a band-aid can be used directly on the middle and lower part of the finger. But if it is in the location of the tip of the finger, band-aids are difficult to rout to cover the entire wound, you can give the middle cut in the location of the adhesive tape on both sides of the band-aids, so that there are four pieces of adhesive tape in layers, and then wrap after the single side of the tape cross can completely cover the entire wound will not loosen.
