PROBLEM TO BE SOLVED: To provide a drip chamber in which separation of bubbles mixed in blood is easy.SOLUTION: A drip chamber has an upper connection part 2, a lower connection part 3, an intermediate connection part 5, a first connection pipe 7 and a second connection pipe 8. A blood inflow pipe 10 is inclined such that the blood inflow pipe 10 ascends to an opening part 10O direction from a blood inflow port 10I to a fourth side part S4 side from a third side part S3 side and to an upper part U side from a lower part D side, and is mounted to the intermediate connection part 5. When deciding an angle at which a horizontal lines SL of a third side part S3-fourth side part S4 direction and the center line CL along the long L direction of the blood inflow pipe 10 cross at an acute angle as a blood inflow angle θ, the blood inflow angle θ is formed at 5-45°.COPYRIGHT: (C)2015,JPO&INPIT【課題】血液中に混入した気泡の分離が容易であるドリップチャンバを提供すること。【解決手段】上部接続部2、下部接続部3、中間接続部5、第一接続管7及び第二接続管8を有する。血液流入管10は、第3側部S3側から第4側部S4側、かつ下部D側から上部U側に向けて、血液流入口10Iから開口部10O方向へ上るように傾斜して、前記中間接続部5に装着している。第3側部S3-第4側部S4方向の水平線SLと、血液流入管10の長手L方向に沿う中心線CLとが鋭角で交わる角度を血液流入角度θと定めると、血液流入角度θは、5°~45°に形成した。【選択図】図1
