HOLLOW-TYPE POLYMER MICRO-NEEDLE ARRAY AND MANUFACTURING METHOD USING MICRO-LENS

摘要

PURPOSE: A hollow polymer micro-needle array and a manufacturing method thereof is provided to secure the elasticity of a polymer material which prevents damage from impacts, to effectively transfer a non-stimulative medicine into a human body by excellent biocompatibility. CONSTITUTION: A manufacturing method of hollow polymer micro-needle array comprises the steps of: forming a mask layer(20) in a substrate(10) with a micro lens(11); coating a polymer material on the upper side of the substrate with the mask layer; forming a lower array substrate of a micro needle by exposing the polymer material(30); re-coating an another polymer material to the lower array substrate and forming the micro needle by exposing the substrate from the back side; and separating the micro needle by removing and developing the substrate. A passage passing through the center of the needle is formed from spraying the polymer materials to the transparent substrate with the form of the micro lens.
