    • An apparatus and method are provided for selectively applying an agent-containing liquid coating to extremely tiny skin piercing microprojections (10). The coating solution is applied to the skin piercing microprojections (10) using a coating technique which selectively coats only the skin piercing microprojections (10) and not the substrate (12) from which the microprojections (10) extend, and then dried. The coating method includes providing an agent-containing coating liquid and conveying the liquid to a liquid holding surface having a coating transfer region. The depth of the coating liquid at the coating transfer region is precisely controlled. The microprojections are then immersed to a predetermined level in the coating liquid. The liquid that coats the microprojections (10) is then dried to form a solid agent-containing coating on the microprojections (10).
    • 提供了一种用于选择性地将含药剂的液体涂层施加到极微小的皮肤刺穿微突出物(10)上的装置和方法。 使用涂覆技术将涂布溶液施加到皮肤刺穿微突出物(10)上,涂覆技术仅选择性地涂覆皮肤刺穿微突出物(10)而不是微突出物(10)延伸的基底(12),然后干燥。 涂布方法包括提供含药剂的涂布液体并将液体输送到具有涂覆转移区域的液体保持表面。 涂层转移区域的涂布液的深度被精确地控制。 然后将微注入物浸入涂布液中的预定水平。 然后将涂覆微喷射体(10)的液体干燥,以在微喷射体(10)上形成含固体剂的涂层。
