Patent ID: 8127459

Claim:
A multifunctional airway evaluator for orotracheal intubation comprising: (a) a first elongated arm having a distal end and an opposing hinge end; (b) a second elongated arm having a distal end and an opposing hinge end connected to said hinge end of said first arm by a pivot connection; said first and second arms movable relative to each other about a pivotal axis of said pivot connection; (c) a planar plate connected to said first arm, extending upwardly from said first arm between said hinge end and a middle portion of said first arm, said planar plate including a distance scale on a front face thereof, disposed along a side edge of said plate at said middle portion of said first arm, toward said distal ends of said arms; said distance scale including a plurality of spaced apart grade lines aligned radially with said pivotal axis and distance parameters associated therewith, wherein when said second arm is rotated to a position relative to said first arm for measurement, one of said grade lines of said distance scale aligned with said second arm indicates a measured distance between said distal ends of said first and second arms at said position; and (d) a gravity-operated angular indicator attached to said planar plate, said gravity-operated angular indicator including an axial pin disposed perpendicular to said planar plate, a rotating disk pivotally attached to and rotatable around said axial pin by gravity, and one or more angular measurement marker affixed adjacent said rotating disk.
