DRIP CHAMBER

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 , the blood inflow angle is formed at 5-45°. 【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 と定めると、血液流入角度 は、５?〜４５?に形成した。【選択図】図１
