ABSTRACT:
The present invention is directed to a waste treating reservoir for treating waste collected using an associated suction system. A disposable receptacle connected to an associated suction system includes a sealed chamber such as a liner and a lid with a pour spout. The waste treating reservoir includes a closed container with an open mouth for storing a waste treating agent. A cylindrical wall forms a diffuser cap and has an open end portion and a substantially closed end portion. The closed end portion has a plurality of apertures opening radially through the cylindrical wall. The open end portion of the cylindrical diffuser cap fits telescopically over the open mouth of the agent container. The reservoir system further includes a double-walled sleeve having an inner wall and a generally concentric outer wall for attaching the combined diffuser cap and agent container to the spout of the disposable receptacle lid. The inside surface of the inner wall of the sleeve sealingly covers the radially opening apertures in the diffuser cap when the cap is in a first position relative to the sleeve. The outside surface of the inner wall and the outer wall are engagable with the cover spout of the receptacle so that the diffuser cap is slidable to a second position in the double-walled sleeve. At the second position, the radial opening apertures are moved axially beyond the inside surface of the inner wall of the sleeve. This allows an open passageway for the waste treating agent to flow from the interior of the agent reservoir to the chamber of the disposable receptacle. The waste treating reservoir of the present invention is configured so the system can be set up prior to the surgical procedure and can be readily activated immediately after the surgical procedure so that hazardous waste can be treated promptly and efficiently.
