    Abstract: An air leak detection device is applied to a thoracic cavity drainage system which, by using negative pressure generated by a vacuum source, aspirates gas in the thoracic cavity of a patient via a water seal chamber in which liquid is received. The pressure between the vacuum source and the water seal chamber is measured by a pressure sensor, and the occurrence of air bubbles created in the water seal chamber is detected on the basis of fluctuations of this pressure.
