ABSTRACT:
A vessel (20) which is divided into compartments (22, 24) receives medical and biological fluid wastes through inlet fitting (12, 14). As the fluid is received, air in the vessel is displaced and is discharged through a vent line (32), either to atmosphere or to a vacuum source. When a level sensor (34) senses that a level of fluid in the vessel is approaching a preselected maximum, a control circuit (40) closes a valve (30) in the vent line, blocking the discharge of air from the vessel and creating a backpressure that stops the receipt of further fluid. Tubing connected to the fittings (12, 14) is disconnected from the patient or other source of fluid and a valve (64) is manually opened to vent the vessel, allowing any residual fluid in the tubing to be drained into the vessel. A drain valve (74) is opened to drain the vessel and the cleaning cycle is commenced. A fittings bell (194) is placed over each inlet fitting such that water with entrained disinfectant from disinfectant reservoir (122) disinfects the inlet nozzles inside and outside. The water with entrained disinfectant is also circulated through a metering reservoir (144) to spray nozzles (146) which spray down the interior surfaces of the vessel. After the nozzle and vessels have been decontaminated, the drain valve is closed and a valve (148) is opened to empty the metered volume of disinfectant solution from the metering chamber into the vessel.
