PERCUTANEOUS ADMINISTRATION DEVICE

摘要

PROBLEM TO BE SOLVED: To improve the configuration of a percutaneous administration device having microscopic projections and to provide a percutaneous administration device capable of administrating medicines aseptically.

SOLUTION: The percutaneous administration device has a substrate section 1 which works as a base for attaching to the skin surface. The substrate section has medicine solution passing holes 1h penetrating through its thickness direction. An attaching surface 1a of the substrate section has the microscopic projections 1c which pierce the skin surface and reach inside or below the stratum corneum. A filtration sterilization filter layer 2 and a medicine solution layer 3 configured to discharge medicine solution from inside when pressed overlie the other surface 1b of the substrate section. The medicine solution discharged from the medicine solution layer passes through the filtration sterilization layer 2 and the medicine solution passing holes 1h of the substrate section successively, and moves to the attaching surface 1a.
