Abstract
A laryngoscope blade which improves the transmission of light from the laryngoscope to enhance the amount of light reflected from an area of interest in a patient. The laryngoscope blade has a channel which extends at least partially though the blade and receives a light source. The channel has a substantially transparent end face which is situated towards the blade end and has an optical clement adapted to reduce the ambient light signal from the light source in the channel.
