PROBLEM TO BE SOLVED: To provide a drip tube capable of preventing outflow of bubbles from an outflow part at a priming time.SOLUTION: There is provided a drip tube 10 including a drip chamber for storing liquid dripping from a drip part 11 and allowing outflow of the liquid from an outflow part 12, and a peripheral wall part 13 for partitioning a peripheral surface of the drip chamber. In the drip tube, the drip chamber is formed by releasing connection between the drip part and the outflow part which are connected mutually, and by elongating the peripheral wall part in the vertical direction.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2016,JPO&INPIT【課題】プライミング時に流出部から気泡が流出することを防止することができる点滴筒を提供する。【解決手段】点滴筒10は、滴下部11から滴下する液体を貯留し流出部12から流出させる滴下室と、滴下室の周面を区画する周壁部13とを備える点滴筒において、滴下室は、互いに接続された滴下部と流出部との接続を解除すると共に、周壁部を上下方向に伸長させることによって形成されることを特徴とするものである。【選択図】図3
