Abstract

A pre-vaccination or pre-procedural topical anesthetic patch which functions not unlike a nicotine patch and which is essentially a round Band-Aid® (trademark) containing a topical anesthetic. The Band-Aid® anesthetic carrying device may be of any shape or size. It is applied to a persons skin at a site where a needle is to be inserted such that the site will have a topical anesthetic applied. When the Band-Aid® is removed from the site prior to a needle being inserted a visible delineation of a target area is visible on the skin. That is, that side of the Band-Aid® which contacts the skin will contain a dye, of any color, although preferably red, in the form of a circle or any other geometric shape, smaller than the diameter or size of the Band-Aid®, whereby when the Band-Aid® is removed the dye will leave a mark at the site which is the “target” area. Particularly important is the fact that once the Band-Aid® or patch is removed, prior to a needle being inserted, the target area or bull'"'"'s eye or a red circle or any other color circle or geometric shape will be left on the skin which clearly delineates where the anesthetic is and, therefore, where the needle should be inserted.
