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 chamber terminates in a pair of parallel, spaced, continuous skin-contacting edges. The housing may contain an absorbent pad. The housing is mounted on a piece of adhesive coated tape by which it is affixed to the skin. Prior to use, the adhesive tape and the housing of the patch system may be provided with a protective release paper.
