Abstract
The utility model provides a stomatoscope, which comprises a handle and a lens which is fixed on one end of the handle, wherein the back surface of the lens is provided with a heating device. The stomatoscope has the advantages that the stomatoscope has heating thermostatic function, thereby preventing the temperature of the lens from being too high, precluding possibility of scalding oral cavities, keeping the temperature of the lens to be constant, reducing check time of the oral cavities, and reducing pain of patients. The stomatoscope is simple in structure, reliable in performance, and convenient to use.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically, relates to a kind of dental mirror with heated constant temperature function.
Background technology
Dental mirror is clinical oral a kind of medical apparatus and instruments commonly used, and its composition comprises handle and eyeglass.Because human body temperature is 37 ℃, be higher than room temperature, dental mirror is under the room temperature condition, temperature is identical with room temperature, when dental mirror was put into the patient oral cavity and observed sufferer, dental mirror often tie mist because of mirror temperature is low, cause fuzzy, the influence observation.So when using dental mirror, the doctor needs and will use then with the eyeglass heating of alcohol burner with dental mirror, after dental mirror eyeglass temperature reduces, repeats heating process again.This has caused following deficiency: 1, obviously prolonged the time of examination of mouth, and sufferer need opened mouth always, etc. examine, has increased the misery of sufferer; 2, the temperature that the eyeglass that uses alcohol burner to heat dental mirror is difficult to control well heating has increased the probability that scald in the sufferer oral cavity.
The utility model content
The purpose of this utility model is to overcome the weak point of traditional dental mirror, and a kind of dental mirror with heated constant temperature function is provided.
The purpose of this utility model reaches through following technical measures:
A kind of dental mirror comprises handle, is fixed on the eyeglass of handle one end, and the back side of said eyeglass is provided with heater.
Say that further said heater comprises heated at constant temperature type PTC critesistor.
Say that further said heater comprises battery and on and off switch, said battery is placed in handle inside, and said power supply is placed on the switch knob, and said battery, on and off switch and heated at constant temperature type PTC critesistor are electrically connected.
Owing to adopted technique scheme, compared with prior art, the utility model has the advantages that:
(1) has the heated constant temperature function, avoid the eyeglass temperature too high, stopped the possibility that scald in the oral cavity.
(2) keep the eyeglass temperature constant, reduced the examination of mouth time, alleviated the misery of sufferer.
(3) simple in structure, dependable performance, easy to use.
Below in conjunction with the accompanying drawing and the specific embodiment this utility model is described further.
Description of drawings
Accompanying drawing 1 is the structural representation of a kind of dental mirror of this utility model;
Accompanying drawing 2 be in the accompanying drawing 1 A-A to profile.
The specific embodiment
Embodiment: with shown in the accompanying drawing 2, a kind of dental mirror comprises handle 1, is fixed on the eyeglass 3 of handle 1 one ends, is equipped with the heater of heated at constant temperature type PTC critesistor 5 as heater element at the back side of eyeglass 3 like accompanying drawing 1.
In the present embodiment, the power supply of heater adopts battery powered, and battery 4 is installed on the inside of handle 1, and handle 1 is provided with on and off switch 2, and battery 4, on and off switch 2 and heated at constant temperature type PTC critesistor 5 are electrically connected.Certainly, also external Dc low voltage power supply can be adopted, waste pollution can be reduced.
This utility model adopts heated at constant temperature type PTC critesistor 5 as heater element, has the characteristics of heated constant temperature, can effectively avoid the eyeglass temperature too high, has stopped the possibility that scald in the oral cavity, has reduced the examination of mouth time, has alleviated the misery of sufferer.
