Abstract
A medical dressing is disclosed comprising an adhesive coated backing member and a medicated compress hermetically sealed between two foils adhesively secured to the backing member. In using the medical dressing the foils are separated, one foil being removed from the rest of the dressing, thus exposing the medicated compress. The compress is thus kept sterile and moist up to the moment of use.
