摘要 |
A lancet comprises a slider having a puncture needle holding mechanism at its one end; a cam ring which has a continuous cam groove, is rotatable about a support shaft, and has a cam ring claw and an anti-return claw for restricting the rotation; a ring spring for applying a force to rotate the cam ring; a rotatable stopper arm for holding and releasing the rotation of the cam ring; and a rotatable ratchet for restricting the direction of rotation of the cam ring. A puncture needle unit comprises a puncture needle body which is integrally molded with a protrusion to be fitted to the lancet, a rotation stop rib, and a puncture needle; and a puncture needle cap which is lightly pressed into the puncture needle body.
