A laryngoscope is adapted for use with two types of blades and has a handle including a power source to which the two types of blade can be connected and also a light source. The first blade is used with the light source carried by the handle and, in this case, serves to switch on the light source when engaged with the handle. The second type of blade carries its own light source and is energised from the power source without simultaneous energisation of the light source in the handle. The light source in the handle may conveniently be included in an adapter. |
