PURPOSE: To absorb a situation change in a supply medical liquid, and secure a safe condition by arranging an adjusting part, which allows passing of gas and checks passing of liquid, on a wall surface of a transparent cylinder body having an inlet to drip out the liquid and an outlet of the liquid. CONSTITUTION: A chamber main body 1 is formed as a transparent cylinder body, and a medical liquid inlet 2 and an outlet 3 are provided. The outlet 3 is connected to a delivery port of a medical liquid through a clamp. An adjusting part 4 composed of a water repellent filter is arranged on a wall surface 4 of the main body 1. This water repellent filter is formed of a gas- liquid filter composed of a material which has watertightness to a liquid material and shows gas permeability to gas such as air, like, for example, a tetrafluoroethylene resin porous film. Indication lines 5 and 6 are arranged on the wall surface of the main body 1 close to the adjusting part 4, and a passing situation of liquid in the main body 1 is made visually observable. The upper indication line 5 is set as a standard maximum value, and the lower indication line 6 is set as a standard minimum value. |
