Abstract
The device for inhibiting contamination from an infectious waste receptacle may comprise a frame, a lid pivotally mounted on the frame, and a bactericidal light source on the underside of the lid to kill bacteria on the exposed surface of the accumulated waste in the receptacle and establish a substantially bacteria-free interface above the infectious waste. The device may further include a plenum having a vent in communication with the interior of the receptacle to maintain the interior of the receptacle at a lower pressure than the surrounding environment and to draw the air displaced from the receptacle away from the the depositor. Finally, the device may include means for applying a disinfectant and/or deodorant to the accumulated waste.
