Abstract
A conformable, gas and vapor permeable, moisture-absorbing adhesive dressing particularly suitable for use as a skin-protecting covering over and about an intravenous injection site. The dressing includes a thin, stretchable, and conformable base layer of moisture-absorbing skin barrier material having both dry and wet tack and having a generally central site-inspection opening therethrough, and a thin, transparent, and conformable cover layer formed of a gas and vapor permeable polymeric film having an underside coated with a gas and vapor permeable layer of pressure-sensitive adhesive that secures the film to the upper surface of the base layer and to a patient'"'"'s skin in the area defined by the opening in the base layer. An arrangement of release sheets covers the underside of the dressing, such sheets being formed and folded to facilitate application of the dressing to a wearer.
