AbstractA chest drainage device having a collection chamber, a water seal chamber and a suction control chamber wherein the suction control chamber includes first and second columns and wherein the top end of the first column is open to the atmosphere and the top end of the second column is in flow communication with a vacuum source. The bottom end of the first and second columns are preferably in flow communication with a float chamber to increase the effective dynamic water height of the liquid in the suction chamber and to decrease the required overall height of suction control chamber of the chest drainage device while maintaining same operational range as prior chest drainage devices.
