To provide a needle stick device capable of lowering the position of a needle to a suitable position of a liquid container by eliminating positional displacement between a needle and a liquid container.A needle card device for puncturing a needle body in a lid body of a liquid container in which a radioactive liquid is sealed is constituted. The needle card device includes a mounting table 12 on which a shielding container 5 that houses a liquid container 7 in which radioactive liquid is sealed and shields leakage of radiation from the liquid, and a needle body 9 above the mounting table 12 A sliding portion 23, a frame body 24, a guide portion 16, and a handle 25, which are needle body moving portions for moving the shielding container 5 upward and downward, and the inclined surface 121 on which the shielding container 5 is placed on the mounting table 12 Has an engaging portion 14 including a concave portion 13 and a convex portion 15 engaging with at least the bottom portion 66 of the shielding container 5.(FIG.【課題】針と液体容器との位置ずれをなくして針を液体容器の好適な位置に下降させることができる針刺装置を提供する。【解決手段】 放射性の液体が封入された液体容器の蓋体に針体を穿刺する針刺装置を構成する。この針刺装置では、放射性の液体が封入された液体容器7を収容し液体からの放射線の漏洩を遮蔽する遮蔽容器5が載置される載置台12と、載置台12の上方で針体9を上下動させるための針体移動部であるガイド板22、摺動部23、枠体24、ガイド部16及びハンドル25と、を備え、載置台12において遮蔽容器5が載置される斜面121が、遮蔽容器5の少なくとも底部66と係り合う凹部13及び凸部15を含む係合部14を有するように針刺装置を構成する。【選択図】図4
