PROBLEM TO BE SOLVED: To provide a microneedle applicator with which a microneedle patch can be easily fitted, and with which there is no risk of skin infection even if being administered consecutively to multiple users.SOLUTION: A microneedle patch applying device includes: a movable cylinder one end of which has an opening portion provided with a catch or a screw for fitting a microneedle patch case； a case body linked to the other end of the movable cylinder； a piston disposed movably in the direction of the opening portion of the movable cylinder, inside the case body； a slide which causes the piston to slide in the opposite direction to the direction of the opening portion； a slide lock which locks the sliding of the slide in the opposite direction； a spring which applies an impact to the piston by means of the sliding in the opposite direction and the locking thereof； a safety shaft which prevents release of the slide lock； and a trigger which is interlocked with the safety shaft. The distal end microneedle patch case is pressed against the skin, however, it is replaced for each application.SELECTED DRAWING: Figure 1【課題】マイクロニードルパッチを容易に装着でき、多数の使用者に連続投与しても皮膚感染の恐れのないマイクロニードルアプリケータの提供。【解決手段】一端がマイクロニードルパッチケースを装着するための留め金又はねじを備えた開口部を有する可動シリンダーと該可動シリンダーの他端と連結したケース本体と、該ケース本体内に該可動シリンダーの開口部方向に移動可能に配置されたピストンと、該ピストンを該開口部方向とは反対方向に摺動させるスライドと、該スライドの該反対方向の摺動を係止させるスライドロックと、該反対方向への摺動とその係止により該ピストンに衝撃を与えるバネと、該スライドロックの解除を抑止する安全軸と、該安全軸と連動するトリガーとを備えたマイクロニードルパッチ適用装置。先端のマイクロニードルパッチケースは皮膚に押圧されるが、１回の適用毎に交換する。【選択図】図１
