Abstract
A combination plastic relatively rigid bite block and soft nasal cannula intended for one-time use for supplying oxygen to a patient's nostrils during an endoscopic procedure. The cannula is fixed into the bite block by an integral clip portion of the cannula extending downwardly from a manifold portion and adhered to the bite block. Flexible nasal prongs extend upwardly from the manifold into the patient's nostrils to supply supplementary gas separately from air breathed through the patient's mouth.
