Abstract

Abstract A wheeled cabinet is provided and includes a vertically elevatable, universally angularly displaceable and longitudinally extendable boom supported therefrom. The free end of the boom supports a horizontal shield structure defining a shallow downwardly opening cavity and the interior of the cabinet houses a vacuum motor including an inlet and an outlet. A vacuum line is provided and includes an inlet end opening into the interior of the cavity of the shield structure and an outlet end coupled to the inlet of the vacuum motor. Further, an exhaust line is also provided and includes inlet and outlet ends. The inlet end of the exhaust line is coupled to the outlet of the vacuum motor and the outlet end of the exhaust line includes structure for securing the exhaust line outlet end over the register of the inlet for the air circulation exhaust duct for an operating room or the like. The shield structure is transparent and includes a substantially planar portion thereof for viewing therethrough and the planar portion is provided with a magnifier mounted thereon for shifting into and out of predetermined position on the shield structure.
