Abstract: An anchoring and occlusive dressing made of a thin polymeric and adhesive material (Class 602, Subclass 42, 52, and 58) in a three dimensional, upside-down “T” shape. The broad, flat area (top of the “T”) can be of varying shapes and sizes with an opening approximately two-thirds the width of the dressing at its widest part. The stem of the “T” is made up of two parallel pieces of the polymeric and adhesive material that are formed perpendicular to the base, but are flexible and will follow the movement of the access device. The parallel pieces are adhesive on the sides that are facing each other with a small area at the top, about 0.3-0.5 inches in height, that is reinforced and non-adhesive. This system allows the total occlusion of the insertion site, not currently accomplished with standard IV dressings, thereby eliminating the open path that allows bacteria access to the site.
