Description of the Related Art A low-pressure suction liquid collector for the chest is often used to maintain a constant internal pressure in the thoracic cavity after a thoracotomy, but as a method, a suction source having a constant suction pressure is used. A water-seal bottle that is used to connect to the chest, guides exhaust gas from the chest under the water surface, guides it to the exhaust passage, and detects gas discharge based on the generation of bubbles at that time, and also detects the degree of negative pressure generation on the chest side. As a medical suction liquid collecting device in which a bottle for storing drainage from the chest is combined into one unit, for example, a suction liquid collecting device as shown in FIG. 3 described in Japanese Utility Model Application Laid-Open No. 62-107843. Vessels have been proposed.

ていた。[0003] As a method of discharging the collected drainage at the time of disposal of these liquid collectors, the container is turned upside down and discharged from a body fluid inlet at the upper part of the liquid collecting part to a sewage sink. However, the inner diameter of the inflow port is often as small as about 10 mm, and is often implemented by adding an operation such as shaking the container hardly so that drainage hardly occurs.
The drainage may be scattered, and especially in the case of drainage from an infectious disease patient, which is a very dangerous operation for medical staff. In addition, in the case of a high-viscosity drainage, it cannot be completely drained, and there is an inherent danger to a medical waste disposal company.
