ABSTRACT:
The present invention provides an underwater drainage apparatus which is adapted to be used for draining a body cavity. The underwater drainage device is provided with two collection chambers in addition to the usual water seal chamber and pressure regulating monometer. The two collection chambers intercommunicate so that the same vacuum is applied to both chambers but a spill over compartment is provided between the two collection chambers to prevent fluid collected in one chamber from passing into the other collection chamber.
