摘要： 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.

摘要翻译： 一种可拆卸地装配到穿刺装置的柳叶刀，其特征在于，具有：柳叶刀，其具有在其前端具有尖锐的柳叶刀尖的刺血针主体，固定在所述柳叶刀身上的柳叶刀套，使得所述柳叶刀头露出;以及弹性变形部， 并且可弹性变形，使得能够改变与柳叶刀主体的距离;环状构件，其与弹性变形部的外周嵌合并且能够通过改变弹性变形部之间的距离而在尖端方向上脱离 变形部和柳叶刀体，以及具有环状构件接触部的壳体，该环状构件接触部存储柳叶刀以能够沿纵向移动并形成在其内周部，使得环状构件与其接触 并且停止在尖端方向移动，并且可以突出刺血针尖端的尖端开口。 这样得到的柳叶器具的形状为：通过使弹性变形部从顶端方向释放的环状部件移动到弹性变形部的前端部和 环状构件接触部，以限制柳叶刀的动作。
