ABSTRACT:
An improved laryngoscope having a blade which is curved and tubular and has an improved light means for illuminating the forward end of the blade. In a number of embodiments of the laryngoscope, a light source is mounted in the upper end of the handle of the laryngoscope so the handle can be used with a conventional laryngoscope blade or a non-conventional laryngoscope blade. In one embodiment, the light source is carried by an adapter removably mounted on the handle near the location where the handle and blade are interconnected.
