PROBLEM TO BE SOLVED: To provide a disposable lancing device of a novel structure, in which a protective cap covering a puncture needle needs not be removed from a housing.SOLUTION: The protective cap 20 is provided to cover a tip 63 of the puncture needle 62. As the protective cap 20 separates from the puncture needle 62 to rotate, a through hole 87 in the protective cap 20 is positioned along the projection route of the puncture needle 62, so that puncture work is performed as the protective cap 20 is supported on the housing 16.COPYRIGHT: (C)2011,JPO&INPIT【課題】穿刺針を覆う保護キャップをハウジングから取り外す必要のない、新規な構造のディスポーザブル型採血器具を提供すること。【解決手段】穿刺針62の針先63を覆う保護キャップ20を設けると共に、該保護キャップ20が該穿刺針62から離脱して回動することにより、該穿刺針62の突出経路上に保護キャップ20の貫通孔87が位置されて、保護キャップ20をハウジング16に支持した状態で穿刺作動が行われるようにした。【選択図】図11
