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.

Claims

1. An airway for insertion into the mouth and pharynx of a patient comprising:

an elongated body including a straight section joined at one end to a curved section extending downwardly from said straight section, said body having an elongate U-shaped central channel having an open top, and a pair of elongate open-sided U-shaped channels on either side of the central channel, said open-sided U-shaped channels having upper and lower defining walls, the channels being adpated for receiving tubular members inserted therein;

a transverse plate secured to the other end of said straight section, the plate being engageable over the mouth of the patient and having apertures communicating with the channels; and

the upper defining wall of one of the open-sided channels having a tube receiving opening therein disposed substantially at the juncture of said straight section with said curved section for receiving and guiding a tubular member inserted through said one channel into the nasopharynx for facilitating drainage thereof when said airway is in place.

2. The airway according to claim 1, wherein said opening extends from said juncture to the end of said body opposite said transverse plate.

3. The airway according to claim 1, wherein said body and said transverse plate are integral.
