ABSTRACT:
A lancet instrument detachably fitted to a lancing apparatus, comprising a lancet having a lancet body with a sharp lancet tip at its tip, a lancet hub fixed to the lancet body so that the lancet tip is exposed, and an elastic deformation part extended from the lancet hub in the tip direction and elastically deformable so that the distance thereof from the lancet body can be changed, a ring-like member fitted to the outer periphery of the elastic deformation part and releasable in the tip direction by changing the distance between the elastic deformation part and the lancet body, and a casing having a ring-like member contact part storing the lancet so as to be movable in the longitudinal direction and formed in the inner peripheral part thereof so that the ring-like member is brought into contact therewith and stopped to move in the tip direction and a tip opening through which the lancet tip can be projected. The lancet instrument thus obtained is so formed that the projection of the lancet tip through the tip opening of the casing is blocked by moving the ring-like member released from the elastic deformation part in the tip direction between the tip of the elastic deformation part and the ring-like member contact part to restrict the movement of the lancet.
