<P>PROBLEM TO BE SOLVED: To provide an apparatus for endermic drug delivery which is painless and safety to a human body, easily disposable, capable of using for quite a lot of drugs, and easily manufactured at low cost. <P>SOLUTION: A needle device 2' having 200 μm of a fine needle is pushed on a skin 4 under normal pressure. Here is stratum corneum 4a, epidermal layer 4b, and corium layer 4c. Then the needle device 2' is pulled up to pull the fine needle out of the skin 4. Further, a pore 5 is temporarily formed on the skin 4 to reach the epidermal layer 4b. A drug 6 is supplied to the upper part of the formed pore 5 and penetrated under the skin through the pore 5. The drug may be applied on the pore 5. Additionally, positive and negative electrodes are put on the skin 4 when the drug 6 is supplied, and so the electric field fainter than usual iontophoresis is applied to enable the drug penetration to promote. <P>COPYRIGHT: (C)2007,JPO&INPIT |
