Abstract A bandage is disclosed comprising a lower portion and a matrix. The lower portion has an upper surface, a base plate on the upper surface, and a post extending from the surface of the base plate. The matrix is attached to the lower portion by means of a hole extending through the matrix which fits around the post. The upper surface of the lower portion can be adhesively coated if desired. The lower portion can also be in the form of a strap. The base plate can be composed of a suitable barrier material such as metal foil or metal foil - polyester laminates. If desired, the matrix can be of a material which can dispense medicaments such as trinitroglycerol.
