Wolaid ETO  For minor wounds including cuts, abrasions, and grazes, sterile gauze swabs are intended to offer cushioning support.  They have strength, softness, and great absorption capacity.  When collecting blood, sterile gauze is helpful because it offers a sterile surface on which to apply pressure to the venipuncture site after the needle has been extracted.  If there have been any leaks during tube change, they can also be used to absorb and clean up any little blood droplets.  Because they are sterile and reduce the chance of infection, it can be applied to open wounds.  Gauze, a light compressive dressing, and a nonadherent dressing are used to dress the wounds.
