Abstract
A puncture device is constituted such that a plunger () is provided with a lever () which is partially restricted in rotation, and a forward urging force is obtained by a contraction restorative force of a tension spring (), and the tension spring () is again expanded with the lever () as a leverage when the plunger () further moves forward due to its inertia from a position where no urging force is not applied, and the plunger () is urged backward by a restorative force of the re-expansion. Further, a puncture needle cartridge is provided with a lancet body () having a puncture needle, and a puncture needle holder () in which the lancet body () is movably stored, and further, the lancet body () has an arm means () and the puncture needle holder () contains a to-be-latched means () that cooperates with the arm means (). 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.
