ABSTRACT:
An oropharyngeal airway tube and bite block assembly having means for connection of a ventilatory resuscitator bag. The bite block provides an air-tight seal between the oropharyngeal airway tube and the gums, teeth, and lips of a patient which, in combination with conventional nostril occluding means, permits closed pulmonary ventilation of a patient without the need for a face mask nor endotracheal tube. The bite block properly locates and provides protection for the airway tube to provide an unobstructed air passage.
