| titleOfInvention | Method for preparing hollow microneedle by using ultraviolet curing process with soluble fiber as core material |
| abstract | The invention discloses a method for preparing hollow microneedles by using an ultraviolet curing process with soluble fibers as core materials, which can be carried out at room temperature, has short preparation time and is beneficial to quickly preparing hollow microneedle arrays in batches. Compared with the existing preparation method of the hollow microneedle, the preparation method adopts an ultraviolet curing molding mode, avoids the heating and melting process of the polymer material, does not need high temperature condition, and has low requirement on preparation environment; the ultraviolet curing process has short forming time, and the micro-needle can be formed by exposing the photoresist for 2-3min under ultraviolet light, thereby greatly shortening the preparation period; the hollow part of the micro-needle adopts a molding mode of taking the soluble PVA fiber as a core material, and the soluble PVA fiber can be dissolved in water, so that the molding process of the hollow part becomes simple and quick, and the molding difficulty of the hollow micro-needle is reduced. |
