    • A puncture device is constituted such that a plunger (2) is provided with a lever (3) which is partially restricted in rotation, and a forward urging force is obtained by a contraction restorative force of a tension spring (4), and the tension spring (4) is again expanded with the lever (3) as a leverage when the plunger (2) further moves forward due to its inertia from a position where no urging force is not applied, and the plunger (2) is urged backward by a restorative force of the re-expansion. Further, a puncture needle cartridge is provided with a lancet body (203) having a puncture needle, and a puncture needle holder (201) in which the lancet body (203) is movably stored, and further, the lancet body (203) has an arm means (302) and the puncture needle holder (201) contains a to-be-latched means (303) that cooperates with the arm means (302). Thereby, the fabrication process is simplified, and plural times of punctures of the puncture needle is prevented, and further, the puncture speed is controlled, and moreover, the used puncture needle is discarded safely.
    • 穿刺装置构成为使得柱塞(2)设置有部分限制旋转的杆(3),并且通过拉伸弹簧(4)的收缩恢复力获得向前的推动力,并且张力 当柱塞(2)由于其惯性从未施加推动力的位置进一步向前移动时,弹簧(4)作为杠杆作为杠杆作用再次膨胀,并且柱塞(2)被向后推动 恢复力量的重新扩张。 此外,穿刺针筒设置有具有穿刺针的刺血针主体(203)和可移动地存储柳叶刀体(203)的穿刺针保持架(201),并且所述柳叶刀体(203)具有 臂装置(302)和穿刺针保持器(201)包含与臂装置(302)配合的待锁闩装置(303)。 由此,能够简化制造工序,并且能够防止穿刺针的多次穿刺,进一步控制穿刺速度,进而安全地丢弃使用过的穿刺针。
