1. A device for guiding the implanting of a sensor within the skin of a subject, the device comprising:
- a housing that is adapted for placement on the outer skin of the subject, said housing defining an area of the skin over which an ultraviolet illuminator and a camera are positioned in said housing at a predetermined distance above the area of the skin, and comprising;
at least one insertion port contiguous with an insertion channel that is formed at a predetermined angle within said housing, said insertion channel having an opening that is adapted to rest against the skin;
said ultraviolet illuminator illuminating a fluorescent material that is previously positioned within the reticular dermis of the subject that is located underneath said housing;
said camera capturing an image of the skin, including the reticular dermis, located beneath said housing;
anda display that permits a user to view said image when passing an applicator and/or sensor through said insertion port and down through said insertion channel and out of said opening such that a tip of said applicator and/or sensor is visible in said image and is positioned within the reticular dermis for delivering the applicator and/or sensor therein.
