    • An advancement mechanism of a lancing device operates to sequentially advance lancets in a cartridge. The advancement mechanism includes a rotary drive gear assembly with a first gear and a second gear that co-rotate in a first angular direction by operation of an inter-gear unidirectional drive mechanism such as a ratcheting mechanism. A second-gear unidirectional lock mechanism, such as a ratcheting mechanism, locks the second drive gear from co-rotating with the first drive gear in a second opposite angular direction without impeding rotation in the first direction. The second gear directly or indirectly rotationally drives a pinion gear, which rotationally drives a cartridge gear to advance the lancets in indexed increments for use. The first drive gear is rotated in the first and second directions by a rack gear of a translating operating handle. In addition, a rotary-gear cap-displacement mechanism and a rotary-gear charging/actuation mechanism are provided in other embodiments.
    • 穿刺装置的推进机构操作以顺序地推进筒中的刺血针。 前进机构包括具有第一齿轮和第二齿轮的旋转驱动齿轮组件,其通过诸如棘轮机构的齿轮间单向驱动机构的操作沿第一角度方向共同旋转。 诸如棘轮机构的二档单向锁定机构锁定第二驱动齿轮与第一驱动齿轮在第二相反的角度方向上与第一驱动齿轮共旋转而不阻碍第一方向的旋转。 第二齿轮直接或间接地旋转地驱动小齿轮,该小齿轮旋转地驱动筒齿轮,以按指数的增量推进刺血针以供使用。 第一驱动齿轮通过平移操作手柄的齿条在第一和第二方向上旋转。 此外,在其他实施例中提供了旋转齿轮盖移位机构和旋转齿轮充气/致动机构。
