ABSTRACT:
An airway for insertion into the mouth and pharynx for assisting intubation comprising an elongate body having a straight section joined to a curved section and a face plate secured to the straight section at its free end. The body of the airway has an elongate U-shaped central channel open at the top and a pair of elongate open-sided U-shaped channels on either side of the central channel. The upper defining wall of one of the open-sided channels has an opening therein through which a tubular member inserted in the channel may be guided for accommodating suctioning of the nasopharynx. A tubular member may be intubated in the other side channel for simultaneously suctioning the hypopharynx.
