A thoracic drainage device including a rigid container having a drainage collection chamber and a liquid seal chamber centered above the collection chamber. A tube adapted for connection with the pleural cavity of a patient is connected to the lid of the device and extends into the liquid seal chamber to a point below the level of an initial amount of liquid provided therein. The liquid seal chamber has a relatively small height relative to its length and width so that it contains a relatively large amount of liquid of shallow depth. The seal chamber has an upper wall with a central opening for the flow of liquid through the opening and into the collection chamber, the upper wall preventing or reducing the flow of liquid out of the liqud seal chamber due to an inadvertent tipping of the device or sloshing during movement from one location to another.
