  • Method of manufacturing microneedle and microneedle manufactured thereby
    Patent number: 10786662
    Abstract: A method of manufacturing a microneedle according to the present disclosure includes a step of preparing a microneedle; a step of cooling the microneedle; and a step of inducing an endothermic reaction of the cooled microneedle, and coating the cooled microneedle with an active ingredient at least once. In accordance with such a configuration, coatability of the active ingredient can be improved due to an endothermic reaction without a separate drying process, thereby providing superior medication.

  • Micro-needle and method of manufacturing the micro-needle
    Patent number: 10716925
    Abstract: Disclosed is a micro-needle including a tip formed using medicine that penetrates into the skin and melts therein; and at least one guide groove each in a stepped shape inward from the outer surface of the tip, and provided to the tip. The micro-needle configured as above may be used to administer a fixed quantity of medicine within a relatively short period of time. Also, since a guide space stepped based on the tip is provided to a base that supports the tip, a large amount of medicine may easily penetrate into the skin.
