Abstract

The configuration and arrangement of the instrument greatly facilitate safe placement of the instrument and an associated endotracheal tube. The instrument includes a handle with an arm extending therefrom. The arm includes a base portion and a distal lifter portion preferably having an angle between 5° and 85°, inclusive, and the lifter is sized and shaped to engage or lift the patient'"'"'s epiglottis, thereby to expose the glottis. In a preferred embodiment, the base portion and lifter portion are substantially the same length, and a viewing device, which is preferably a CCD or CMOS camera positioned near the transition portion between the base and lifter portions, is aligned to provide a perspective view toward the distal end of the lifter. Lights, which are preferably LED units, are positioned toward the distal end of the lifter to facilitate viewing. A transparent protective sheathing may be positioned over the assembly to facilitate cleaning and provide sterile multiple use of the device, and the lifter may be pivotally secured to the base portion to facilitate on-site adjustment by the practioner.
