(a) Field of the Invention
The present invention relates to an electrical heater device for heating a clinical mirror.
(b) Description of Prior Art
Clinical mirrors of the type comprising a mirror stem with a mirror element at one end and for use particularly in viewing areas of the mouth of patients to examine the throat area or the teeth area of the mouth, require heating to sterilize and to prevent fogging of the mirror when inserted in the mouth of the patient. A common practice, at the moment, involves heating the mirror element with an alchol burner. A disadvantage of the use of such burners is that it is dangerous to use in a doctor's office as there exists a fire hazard, and require filing, from time-to-time. This is a messy operation and a supply of oil has to be maintained. Furthermore, such burners do not release uniform heat and the mirror could be damaged thereby.
