공기 누설 검출 장치(5)는, 흡인원(4)이 발생시키는 부압을 이용하여, 환자의 흉강 내의 기체를 액체가 거두어진 수봉실(11)을 통해 흡인하는 흉강 드레인 시스템(1A)에 적용된다. 흡인원(4)과 수봉실(11) 사이의 압력을 압력 센서(15)로 측정하고, 그 압력 변동에 기초하여 수봉실(11)에서 발생하는 기포의 발생을 검출한다. An air leak detection device (5) is applied to a thoracic cavity drainage system (1A) which, using negative pressure generated by a vacuum source (4), aspirates gas in the thoracic cavity of a patient via a water seal chamber (11) in which liquid is received. The flow rate between the vacuum source (4) and the water seal chamber (11) is measured by a flow rate sensor (15), and the occurrence of air bubbles created in the water seal chamber (11) is detected on the basis of fluctuations of this flow rate.
