A combination fluid collection and disposal apparatus for collecting and disposing fluid aspirated from a patient from a surgical procedure is disclosed which comprises a collection unit for collecting the fluid and a treatment unit for coupling with the collection unit to remove the fluid from the collection unit and to dispose the fluid. The collection unit comprises a reservoir for the temporary storage of fluids aspirated from the patient, a vacuum port for connecting the collection unit to a vacuum source, and a vacuum line connecting the vacuum port to the reservoir. The collection unit also comprises at least one suction port adapted for connection to a suction tube for aspirating fluids from the patient, a suction line connecting the suction port to the reservoir, and a drain generally adjacent the bottom of the reservoir. The treatment unit comprises a washing fluid port adapted for connection to a source of washing fluid, a coupling for coupling the treatment unit to the suction port for providing washing fluid through the suction port, through the suction line and to the reservoir for cleaning the suction port, suction line, and reservoir. The treatment unit also comprises a coupling for coupling the treatment unit to the drain for removing the accumulated aspirated fluid and the washing fluid from the reservoir.
