Abstract: PURPOSE: A hollow micro needle whose external shape is changeable is provided to control an effective length, the inner diameter and outer diameter of an upper part, the diameter and the hardness of a lower part, a sharpness degree, an inclined angle, an aspect ratio, and a bending degree. CONSTITUTION: A method for manufacturing a hollow micro needle whose external shape is changeable comprises the following steps. A viscid solution is spread on a board. The viscid solution contacts a frame. The board, the frame, or the board and the frame are lifted to separate the frame from the board which contacts the frame so that a solid micro structure is manufactured. Metal is deposited on the solid micro structure. Metal is plated on the surface of the micro structure while protecting the upper part of the solid micro structure on which metal is deposited. A hollow micro structure is obtained by eliminating the solid micro structure.

Abstract: The present invention relates to a method for fabricating a hollow microneedle having a variable appearance. The method makes it possible to vary the length of the microneedle, the outer and inner diameters of the upper and lower parts thereof, the aspect ratio, the sharpness, and the structural bending rate thereof, in accordance with the purposes of the same. Accordingly, the appearance of the hollow microneedles according to the present invention can be varied with flexibility according to various purposes, such as the transferring of medication and the taking of a blood sample, and to various factors, such as the target part for the medication transfer, the depth of the medication transfer, and the amount and viscosity of the medication. Thus, the microneedle can be used as a multi-purpose device for transferring medication.
