Abstract
An improved laryngoscope. In one embodiment a laryngoscope blade includes a main blade portion and blade tip and a blade base. The main blade portion has a posterior surface, a distal end and proximal end. The blade tip extends from the distal end of the main blade portion. The blade tip also has a width that is flared wider in a first direction than a width of the main blade portion. The blade tip is further positioned at a select angle with relation to the posterior surface of the main blade portion. The blade base coupled to the proximal end of the blade.
Claims5
A laryngoscope blade, the blade comprising:
- a main blade portion having a posterior surface, a distal end and a proximal end, the posterior surface having a length that is generally straight from the proximal end to the distal end;
- a blade tip extending from the distal end of the main blade portion, the blade tip further extending beyond a width of the main blade portion from a first side of the main blade portion, the blade tip further extending from the posterior surface of the main blade portion at a select angle;
- a first tongue displacement plate extending from a second side of the main blade portion at generally a right angle, the first tongue displacement portion further extending along a select length of the main blade portion proximate the distal end of the main blade portion;
- a second tongue displacement plate extending from the first displacement plate at generally a right angle, the second displacement plate further extending from the first displacement plate in a direction that is generally away from the main blade portion, the second tongue displacement plate further having a surface that is positioned in an opposite direction as the posterior surface of the main blade, the surface of the second tongue displacement plate forming a plane that is generally parallel with an axis formed by the length of the posterior surface;
- and
- a blade base coupled to the proximal end of the main blade portion, wherein the generally straight length of the posterior surface extends from the blade base at generally a right angle.
