Abstract

Light conducting clear plastic blade for insertion into a body cavity. e.g. as part of a laryngoscopo, illuminated by a light source contained in gap 6 where light passes through the proximal end 1 of the blade and is reflected off surface 2 by total internal reflection and is then conducted out of the blade through light carrying section 3. The blade also has a channel 5 allowing passage of tubes into said body cavity. The blade is particularly useful in neo-natal laryngoscopes and may also be used in nasal or gynaecological speculae with the advantages of disposability and reduced trauma to soft tissues. <IMAGE>
