Abstract
Abstract A dressing device and method are described, for use with a needle that is injected into the skin. The dressing device comprises a cover sheet and a gel medium attached to the cover sheet, the gel medium being transparent and effective to reseal after being punctured by the needle. Most importantly, the gel medium includes a sterilizing agent. Injection of the needle into the skin occurs only after the needle penetrates the gel medium, so that the needle is disinfected or sterilized.
