A SKIN NEEDLE DISK FOR SKIN PRETREATING AND METHOD FOR ARRANGING THEREOF

摘要

The needle plate has needles arranged in a way of spacing the needles radially closer one to next one in the radial direction away from the center at an equal angled distance between the neighboring directions to have a uniform number of needles per an area to give a uniform needling effect on the whole target area of skin. The needle pretreated skin area is applied with an insulin patch for percutaneous absorption of insulin through the needle holes in the epidermis layer. The needle holes are enlarged with the help of a battery apply power current for oscillation of needles on the skin.
