1. An apparatus for handling biological and medical fluid wastes, the apparatus comprising:

  • at least one inlet fitting for interconnection with a flexible tube which is connected with a source of the fluid waste, the inlet fitting including a first connector for interconnection with the flexible tube and a second connector disposed adjacent the first connector;

    a collection vessel connected with the inlet fitting such that received fluid waste flows into the vessel;

    a drain line and a drain valve connected with the vessel for draining the vessel;

    a disinfectant liquid source which supplies a disinfectant liquid;

    a bell fitting connected with the source of disinfectant liquid and connectable with the second connector with the first connector received in and displaced from the bell fitting, such that a fluid circulation region is defined between the bell fitting and the first connector such that the disinfectant liquid flows around and through the first connector to the vessel;

    a vent line and a first vent valve connected between the vessel and one of (1) a vacuum source and (2) the atmosphere for removing gases displaced by collected fluid waste from the vessel;

    a level sensor for sensing a level of fluid waste in the vessel;

    an automatic shut-off circuit connected with the level sensor and the vent valve for blocking the removed gases from the vessel in response to the level sensor sensing that the fluid level in the vessel is approaching a preselected capacity to slop the vessel from receiving the fluid waste.
