An improved underwater drainage device having a baffle system preferably incorporated into the water seal column positioned in flow communication with the patient\s pleural cavity wherein the baffle chamber consists of a baffle insert having a baffle tube and a plurality of spaced downwardly directed baffles. And wherein the baffle tube of the present invention includes a tapered outer wall directed toward the first baffle and sidewalls having a plurality of side openings to allow the water seal to flow downwardly therethrough once the negative pressure from the patient\s pleural cavity has dissipated.

An underwater drainage device for removing liquids and gases from the body of a patient comprising, a first collection chamber in flow communication with the body of a patient wherein fluid from the patient will be suctioned into the first collection chamber, an underwater seal chamber having a predetermined amount of liquid therein and wherein the underwater seal chamber is in flow communication with the first collection chamber, a source of negative suction pressure in flow communication with the underwater seal chamber, a means for providing the flow communication between the first collection chamber, the underwater seal chamber and the source of suction, said underwater seal chamber including a water seal column and an upper baffle chamber wherein, as the pressure in the first collection chamber decreases below the regulated suction pressure from the suction source, the liquid in the underwater seal chamber will be drawn upwardly through the water seal column into the upper baffle chamber, the baffle chamber further having a volume greater than the predetermined volume of liquid capable of being drawn into the water seal column and said baffle chamber including a top and bottom end and opposed sidewalls, a plurality of baffles spaced along and extending from the sidewalls of said baffle chamber to obstruct the flow of liquid through the baffle chamber, and wherein the bottom end of said baffle chamber includes a baffle tube extending upwardly therefrom and having top and bottom ends aligned in flow communication with the water seal column wherein said bottom end of said baffle tube has a bottom opening therein having a larger area than the top opening on said top end of said baffle tube.
