There is nothing more frustrating than working hard to place an IV catheter in a critically ill patient only to have the patient remove it. The IV Catheter Guards are a quick and inexpensive way to deter your patients from chewing or licking on their IV catheters. They are made of a thin, lightweight, flexible plastic with holes for air circulation. The IV catheter guard is held in place by Velcro straps that wrap around the limb. The rough surface of the Velcro seems to deter most patients from licking. Straps are reusable, but also inexpensive to replace if damaged. University tested and recommended.
