An oral airway which is inserted into the pharynx of a patient through the mouth while the patient is undergoing general anesthesia or is undergoing respiratory treatment such as is carried out with cardiopulmonary resuscitation. The oral airway includes a curved hollow, tubular longitudinally extending body member. The body member has a distal end portion for insertion into the patient's mouth and pharynx and a proximal end portion for location at the mouth of the patient. The distal end portion of the body member of the oral airway is extended and shaped so as to be operative to seat deep in the patient's hypo-pharynx and surround the patient's epiglottis and glottis, thereby to hold the patient's soft tissue away from the air channel opening of the patient. |
