## Abstract

An oral airway for providing an air passage to a patient's trachea. The oral airway includes a curved section and a straight section with the curved section having spaced-apart curved upper and lower members and the straight section having spaced-apart planar upper and lower members with the same width. The curved upper member has the same width as the planar upper member with the curved lower member having a greater width than the width of the lower planar member. The width of the curved lower member is greater than the width of the planar lower member and the distance between the curved upper and lower members is greater than the distance between the planar upper and lower members. The curved lower member has a generally inverted V-shaped cross-section.

## Claims

### Claim 1

An oral airway to provide an air passage to a patient's trachea, comprising:
a straight section having inner and outer ends adapted to fit between the patient's teeth;
a curved section adapted to fit over the patient's tongue and extending to the oropharyngeal area;
said straight section including a substantially planar upper member and a substantially planar lower member which are spaced-apart by a medial web extending therebetween;
said planar upper and lower members of said straight section having substantially the same widths;
said outer end of said planar upper member having an upwardly extending flange;
said outer end of said planar lower member having a downwardly extending flange;
said flanges externally overlying the lips of the patient;
said curved section comprising spaced-apart curved upper and lower members which are spaced-apart by a medial web extending therebetween;
said curved upper member of said curved section having substantially the same width as said planar lower member of said straight section;
said curved lower member of said curved section having a greater width for substantially its entire length than said planar lower member of said straight section;
said curved lower member of said curved section having a generally inverted V-shaped cross-section.

### Claim 2 (depends on 1)

The oral airway of claim 1 wherein said inverted V-shaped cross-section of said curved lower member defines diverging wing members having side edges.

### Claim 3 (depends on 1)

The oral airway of claim 1 wherein the distance between said curved upper and lower members at their juncture with the associated medial web is substantially the same as the distance between said planar upper and lower members of said straight section.

### Claim 4 (depends on 2)

The oral airway of claim 2 wherein said wing members extend outwardly and downwardly from the associated medial web.

### Claim 5 (depends on 2)

The oral airway of claim 2 wherein said curved lower member of said curved section has side edges and wherein said side edges of said wing members are spaced outwardly of said side edges of said curved upper member of said curved section.

### Claim 6 (depends on 5)

The oral airway of claim 5 wherein the distance between the respective side edges of said curved upper and lower members and said side edges of said curved upper member is greater than the distance between said planar upper and lower members of said straight section.
