A device for controlling visibility and access to central venous access devices is comprised of a two-sided body fitted around the torso of a patient. The device has an interior surface and an exterior surface. The interior surface is fitted with a layer of absorbent, wicking material and further includes strips of anti-slip material to fix the device in place. A flexible window is positioned between two lumen retaining flaps and fixed between the interior and exterior surfaces. The lumen retaining flaps create pockets to store and protect lumens attached to intravenous tubing. The body includes a flexible closure including a resilient gauze section to provide flexibility and size adjustability. The window allows visual access to the percutaneous site and prevents patient tampering.
