Abstract
A laryngoscope blade includes an upper wall, a lower wall, and a side wall joining the upper and lower walls. The upper wall includes an upper lip engaging portion and an upper gum engaging portion which are contiguous with one another. The lower wall includes a tongue engaging portion and a tip portion disposed for engaging and lifting the epiglottis. The gum portion is substantially parallel to a major extent of the lower wall, whereas the lip portion extends at an acute angle with respect thereto. An inner surface of the upper wall, at the juncture of the gum portion and the lip portion, is provided with a groove and the inner surface of the tip portion is provided with another groove. The bottom surfaces of the grooves are aligned with one another, such that a line of sight extends along such surfaces from each end of the blade.
