Abstract
A patch system for use on the skin of a human or animal subject for predictive testing, diagnostic testing and to serve as a dermal delivery system for drugs. The patch system comprises an open, one-piece, inverted dish-shaped housing of non-toxic, inert, soft and flexible material. About its periphery the housing terminates in at least one and preferably a pair of parallel, spaced, continuous, skin-contacting edges. The housing may contain an absorbent pad. About its periphery and spaced slightly upwardly from the one or more skin-contacting edges, the housing has a planar flange extending outwardly from its exterior surface. The bottom surface of the flange is adhesive coated. The adhesive coated flange affixes the housing to the skin. Prior to use, the housing and its peripheral flange may be provided with a protective release paper.
