Abstract
The present invention relates to a biological component measurement apparatus set, in which a puncture mechanism for puncturing skin of a subject to collect a sample blood is integrated with a biosensor measurement apparatus. The puncture mechanism includes a puncture needle, and a cap which is detachably engaged with a body of the apparatus, wherein the cap has a skin contact surface which is brought into contact with the skin for puncturing. The skin contact surface having an opening through which the puncture needle moves to puncture the skin, and is shaped so as to fit a surface shape of the skin to be punctured. The set includes a plurality of different caps each corresponding to a different sample collection site so that a plurality of different sample collection sites can be selected.
