The Zerowet Supershield is used without a needle or IV catheter. The integrated nozzle creates the high-pressure necessary for effective irrigation.
Simply place the rim of the super shield on the patient and attach the super shield to the end of a 20cc or large syringe, dip it into the reservoir, draw up the irrigation solution and irrigate the wound. Repeat as many times as necessary to adequately cleanse the wound. It is faster, easier and better!
