    Abstract: A speculum holder and illuminator comprises a handle containing battery and switch compartments separated by a sealed wall. A speculum support sleeve extends across the top and has a forward recess to hold a tubular speculum, and a viewing opening at the rear. A lighting assembly in the sleeve projects light forwardly in the speculum and is powered by a battery in the battery compartment connected through a switch in the switch compartment. An alternate form has a spring clip for temporarily holding it in a tubular speculum. A conductor card extends to a battery pack on the user's belt where it is supported on a crank-wound reel enabling it to be extended and retracted as needed.
