Abstract:
(EN) A microneedle structure, a manufacturing method therefor and a manufacturing apparatus therefor are presented. The microneedle structure manufacturing method according to one embodiment of the present invention comprises the steps of: a) injecting, into a lower mold comprising a microneedle intaglio, a polymer solution containing a biocompatible polymer; and b) coupling a shape control mold, which comprises a protrusion, to the lower mold such that one end of the protrusion of the shape control mold is impregnated with the biocompatible polymer solution injected into the microneedle intaglio.
(FR) L'invention concerne une structure de micro-aiguille, sa méthode de fabrication et un appareil de fabrication associé. La méthode de fabrication de structure de micro-aiguille selon un mode de réalisation de la présente invention comprend les étapes consistant à : a) injecter, dans un moule inférieur comprenant une micro-aiguille en creux, une solution de polymère contenant un polymère biocompatible; et b) coupler un moule de contrôle de forme, qui comprend une saillie, au moule inférieur de telle sorte qu'une extrémité de la saillie du moule de contrôle de forme est imprégnée avec la solution de polymère biocompatible injectée dans la micro-aiguille en creux.
(KO) 마이크로니들 구조체, 그 제조방법 및 그 제조장치가 소개되며, 본 발명에 일 실시예에 따른 마이크로니들 구조체의 제조방법은 a) 마이크로니들 음각을 포함하는 하부 몰드에 생체적합성 고분자를 포함하는 고분자 용액을 주입하는 단계 및 b) 돌출부를 포함하는 형상제어몰드의 상기 돌출부 일단이 상기 마이크로니들 음각에 주입된 생체적합성 고분자 용액에 함침되도록 상기 형상제어몰드를 상기 하부 몰드에 결합하는 단계를 포함한다.
