Embodiment Construction

[0044] figure 1 Shown is a blade 1 comprising an opening 2 , a handle 3 with a connecting means 4 to connect the sheath blade 1 to a laryngoscope, and a blade end 5 with a blade tip 6 .

[0045] The blade 1 comprises a channel 9 extending from the handle 3 to the end face 7 . Both sides of the end face are provided with end face supports 10 to improve the structural strength of the laryngoscope blade. The channel 9 is suitable for the insertion of an image capture device and / or an illumination device.

[0046] figure 2 is a cross-sectional view of the end face 7 . The end face includes an optical element 11 for receiving light from a light source 17 . Optical element 11 includes a prism 15 and is bounded by a gap or channel 13 that separates optical element 9 from a second optical element 12 adapted to receive light from the patient's throat (or other The relevant part of the ) reflects the light back and transmits the light to the camera 19.

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 element adapted to reduce the ambient light signal from the light source in the channel.
