PROBLEM TO BE SOLVED: To collect a desired amount of a body liquid without deterioration of the collected body liquid.SOLUTION: A body liquid collection tool comprises: a suction part 1 for sucking a body liquid a body part 2 comprising a ventiduct 21 for transmitting gas for discharging the body liquid sucked by the suction part 1 and an inhibition part 3, which is disposed between the body part 2 and the suction part 1, having an opening 31 which has inner diameter on a surface contacting the suction part 1, which is smaller than inner diameter of the suction part 1, and which inhibits entry of the body liquid sucked by the suction part 1 to the body part 2. On the surface where the suction part 1 and the inhibition part 3 contact, the inner diameter of the opening 31 formed on the inhibition part 3 is smaller than inner diameter of the suction part 1, therefore the body liquid sucked by the suction part 1 is inhibited from being sucked by an excessive amount relative to a predetermined amount.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】採取した体液を変質させることなく、所望の量の体液を採取する。【解決手段】体液を吸引する吸引部1と、吸引部1が吸引した体液を排出するための気体を通す通気路21を有する本体部2と、本体部2と吸引部1との間に設けられており、吸引部1と接する面における内径が吸引部1の内径よりも小さな内径を有する開口部31を有し、吸引部1が吸引した体液が本体部2に流入することを阻止する阻止部3と、を備える。上記の吸引部1と阻止部3とが接する面において、阻止部3に形成された開口部31の内径が、吸引部1の内径よりも小さいことにより、吸引部1により吸引された体液が、所定量よりも多く吸引されることを阻止する。【選択図】図1
