1L Suction bottle

When the vacuum outlet is turned on, an air negative pressure will be generated in the suction bottle, which will direct dirt (such as blood, sputum, etc.) from the hose into the bottle. When the height of the liquid in the suction jar reaches a certain height, the stop valve on the cap will start to work, cutting off the liquid into the pipeline to prevent the liquid in the suction jar from overflowing.
