The present invention relates to a micro-needle device, and a pipe-like flow in which the drug flow is formed , and the needle is formed to be in contact with the skin attached to the lower end That the through-aperture in the top and bottom is formed, the lower portion of the needle is coupled to the aperture, and the lower base of the needle is attached to the through hole formed to protrude outward And the through-hole is formed in the through hole and the corresponding position of the lower base, is provided in the upper part of the lower base to engage the upper portion of the needle in the through-hole, and that the outer upper base of the drug is introduced via the through hole Is provided in the upper portion of the upper base, on top of the drug-containing section is formed to be receiving the drug, the lower the through up and down and is connected to the drug containing part of the drug contained in the flow channel, and through the drug containing part of the upper base The ball and communicating with the inlet is formed to be a drug, the drug is in communication with the inlet chamber and the drug lateral grooves are formed in the horizontal direction Is provided on the lateral grooves of the medicament chamber, the opening and closing means for selectively opening and closing the inlet to the drug and the microneedle device is configured including a technological base. Accordingly, the flow through the drug flow in the needle at the same time and in the Sikkim form a microporous skin tissue using the needle as required by the IAS has the advantage that can be injected directly.본 발명은 마이크로 니들 장치에 관한 것으로, 파이프 형상이고 약물이 유동되는 유동로가 형성되며, 하단부에 피부와 접촉되는 첨부가 형성된 니들과 상하부로 관통된 통공이 형성되고, 상기 통공에 상기 니들의 하부가 결합되며, 상기 니들의 첨부가 통공 외측으로 돌출되게 형성된 하부베이스와 상기 하부베이스의 통공과 대응되는 위치에 관통공이 형성되고, 상기 관통공에 상기 니들의 상부가 결합되도록 상기 하부베이스의 상부에 구비되며, 상기 관통공을 통하여 외부의 약물이 유입되는 상부베이스와 상기 상부베이스의 상부에 구비되며, 상부에는 약물이 수용되는 약물수용부가 형성되고, 하부에는 상하로 관통되고 상기 약물수용부와 연결되어 약물수용부에 수용된 약물의 이동통로가 되며 상기 상부베이스의 관통
