ABSTRACT:
An air leak detection chamber is provided which is adapted to be attached to a conventional pleural drainage device. The air leak detection chamber has a pair of passageways which are connected in series in the passageway of the pleural drainage device leading from the underwater seal or from the oneway valves disposed in the passageway leading from the collection chamber to the suction source of the pleural drainage device. The detection chamber has a water filled tube therein and any air passing from the pleural drainage device will displace the water within the tube. Thus, a physician may readily observe the volume of air passing from the pleural cavity of a patient and determine the extent of any air leak in the pleural cavity.
