The present invention is an oro-fiberscopic biteblock. The biteblock is utilized during oral fiberscopic procedures. The biteblock includes a main structure having an orifice sized to accommodate entry of a fiberscope, such as an endoscope, through the orifice. The biteblock includes an extension extending inward from the main structure when positioned within the mouth of a patient. On each side of the orifice is a loop for handling and positioning the biteblock within the patient's mouth. The biteblock includes an exhalation tube running from the extension to a monitoring device which allows monitoring of the patient's expelled gases. In addition, an inhalation tube may be used to provide supplemental oxygen to the patient. The biteblock is positioned in the mouth of the patient with the mouth of the patient surrounding the extension. The tubes include openings which are located on the extension and lie in the interior of the mouth to provide monitoring of uncontaminated gasses expelled by the patient. |
