摘要

A surgical drainage system is provided for the drainage of fluid from a body cavity which comprises a first collection compartment, a second compartment, and a connecting passageway for connecting the first and second compartment in fluid communication. The volume of the connecting passageway is insignificant with respect to the second compartment and the connecting passageway provides a visual indication of changes in pressure in the body cavity by reason of oscillation of collected fluid therein.
