- lancet A3 as shown in FIGS. 16 and 17 can also be used.
- FIGS. 16 and 17 the same reference numerals are given to the same elements as those of puncturing apparatus B 2 or lancet A 2 described above.
- the lancet A 3 is rotatable relative to a lancet body 2 ′′ having a puncture needle 1, a tubular portion 3 ′′ for accommodating the puncture needle 1, and a lancet body 2 ′′ and a tubular portion 3 ′′.
- the lancet body 2 is provided with a rotating portion 7" that can move relative to the lancet body 2 "in the axial direction of the puncture needle 1.
- the lancet body 2 has a female thread portion 28" having a thread groove formed on the inner surface, and a guide groove 29 “extending in the axial direction of the puncture needle 1.
- the tubular portion 3 It has a guide projection 39 "that engages with # 29".
