MICRONEEDLE PREPARATION DEVICE AND MICRONEEDLE PREPARATION METHOD

WIPO Patent Application WO/2021/077628

A1

The present invention relates to a microneedle preparation device and a microneedle preparation method, and aims to reduce the production costs of microneedle preparation and improve the efficiency and quality of microneedle preparation. The microneedle preparation device comprises a substrate, an elastic female mold, a horizontal movement mechanism, a vertical movement mechanism, a filler and a roller shaft mechanism; the elastic female mold is disposed on the substrate, and pits that match needle bodies are formed on the surface of the elastic female mold; the filler comprises a storage cavity used for storing a solution for preparing microneedles; and the roller shaft mechanism is disposed on the filler and comprises a roller shaft. During an actual application, the roller shaft applies pressure to the elastic female mold under the drive of the vertical movement mechanism to a preset pressure value, and then moves in the horizontal direction on the elastic female mold under the drive of the horizontal movement mechanism to remove air in the pits. The solution released from within the storage cavity coats the elastic female mold. In the foregoing manner, the filling efficiency is high and the filling effect is good.
