Title: Suction bottle assembly

Abstract: A suction bottle assembly for effecting drainage from a patient. The assembly has a float, which is responsive to the level of drainage in the bottle, that is connected to the cover by a preferably parallel bar bracket. The bracket causes the float to rise substantially vertically and also seals off the vacuum inlet and opens a vacuum relief valve to create a pressure balance within the bottle with the outside atmospheric pressure, thus preventing overflow.
