BITE BLOCK ASSEMBLY ADAPTED FOR ADJUSTABLE MOUNTING AND HOLDING OF ORAL AIRWAYS AND METHOD OF USING SAME A bite block and airway assembly comprising a generally U-shaped resilient block having upper and lower teeth or gum-engaging surfaces and having an aperture formed centrally through the block between such surfaces and communicating between the interior and exterior of the block for matingly receiving and frictionally holding a tongue depressor type oral airway tube. The frictional engagement of the block with the airway tube provides slidable adjustability with respect to the depth of insertion of the tube while firmly holding the tube in any of a plurality of slidably adjustable positions. The tube-engaging aperture formed in the block is of oval shape for matingly and adjustably engaging any of a number of different types of airway tubes having different cross-sectional configurations. The device is usable as an oral protective device in electro-convulsive therapy or, alternatively, as an oral filler for the administration of gaseous anesthetic to edentulous patients. |
