摘要： There is provided a lancet assembly with a possibility of the lancet structure being inadvertently pushed without an intension of pricking. The lancet assembly comprising a lancet structure 200 and a lancet holder 100 which holds the lancet structure, in such a constitution that by pressing the lancet structure into the lancet holder, the following steps are carried out: the step of separating a lancet cover 214 from a lancet body 216 so as expose a distal end portion 232 of a pricking element 220, and then the step of launching the lancet body having the distal end portion of the pricking element exposed so as to prick a predetermined portion, characterized in that a trigger 300 used to launch the lancet body has a pushbutton 117 exposed through an opening 120 provided in a side surface 101 of the lancet holder, the lancet body of which the distal end portion 232 of the pricking element 220 is exposed is launched by moving the trigger forward while the exposed pushbutton is pressed into the lancet holder.

摘要： There is provided the pricking device that allows it to load the unspent lancet assembly into the injector, and that inhibits loading of the unspent lancet assembly into the injector. The pricking device has the notched portion formed on the edge of the opening end of the lancet holder, and the plate spring component is provided on the inner wall of the housing of the injector. One end of the plate spring component is secured to the injector housing, whereas the other end of plate spring component is free end, and the tip end portion of the free end being provided with the hook-shaped portion. In the spent lancet assembly, the notched portion engages with the hook-shaped portion so that the loading becomes impossible. In the unspent lancet assembly in which the lancet body is secured to the lancet holder such that the protrusion of the lancet body is located rearward with respect to the notched portion, the protrusion serves to expand the free end outwardly so that the notched portion does not engage with the hook-shaped portion. As a result, the unspent lancet assembly can be inserted into the injector.
