Abstract
An underwater drainage apparatus is provided with an underwater seal formed by fluid from the pleural cavity of the patient. The dead air space within the underwater drainage apparatus is reduced to a minimum by dividing the collection chamber into a plurality of compartments and providing seals between the compartments which are dissolved when liquid from the preceding compartment reaches the dissolvable seal. A passageway is provided in the air space directly above the underwater seal chamber to connect to the outlet to suction and a one way valve is provided in this passageway.
