A system for draining pleural cavities. A container having a plurality of cavities is employed with a vacuum source and an inlet from the patient. In the first cavity, a port is defined to limit the liquid contained therein. This port opens into a second cavity for collection of drained fluids. A vacuum regulator mechanism is incorporated at one end of the container to prevent injury to the patient. Thus, a water seal is defined about the inlet tube. A separate cavity collects drained fluids and a third area provides vacuum control.
