ABSTRACT:
The specification discloses a medical suction apparatus including a generally rigid container. A pair of conduits extend from the lid of the container for connection to a patient area to be drained and for connection to a vacuum source. In operation, fluid is drawn from the area to be drained and collected within the container. A flexible float valve is connected to the underside of the lid and is operable upon fluid overflow conditions to obstruct the vacuum conduit to prevent fluid from being drawn into the vacuum source.
