Abstract
The utility model discloses a condensate-proof mouth mirror, which is a medical mouth mirror, the front surface of a glass sheet is deposited with a metal oxide semiconductor transparent conductive heating film, and the back surface is provided with a reflective metal coating by vacuum evaporation. The utility model can be electrifying heated when using, the mirror surface temperature is adjustable (37-39DEG. C), the reflected image is clear, the operation is simple and rapid, and a dry cell can be served as a power supply (1.5-3.0V ). The utility model overcomes the disadvantages of the fog on the mirror surface and the unclear images of the general mouth mirror, so the utility model has protruding practicability to cold areas or cold season, in particular to field aid.
Description
This utility model belongs to medical apparatus and instruments.
Present medical mouth mirror is that the circular glass that has handle reflects little mirror, needs during use little mirror is stretched in the oral cavity, observes the position of directly can't see by the reflected image of little mirror.Usually, ambient temperature and humidity all are lower than the temperature and humidity in the human oral cavity, therefore when little mirror is put into the oral cavity, produce one deck cloud and mist on the minute surface immediately, cause reflected image unintelligible, and is especially even more serious at cold district or cold season.For fear of producing cloud and mist, generally be to toast little mirror with alcohol burner, improve the temperature of little minute surface, between so not only having mistaken but also be difficult for accurately control temperature, have a strong impact on the inspection effect.
The purpose of this utility model is in order to overcome the above-mentioned shortcoming that mouth mirror exists, provide a kind of can be antifog, the novel clearly mouth mirror of reflected image.
Main points of the present utility model are at the front of little glass wafer high-temperature chemical gas phase sediment layer of metal oxide semiconductor electrically conducting transparent heating thin film (tube claims transparent electric heating film), make electrode and outer lead on film.At little glass wafer back side vacuum evaporation layer of metal reflectance coating, be encapsulated in then on the handle, connect with the mains and potentiometer switch.Constitute a complete whole Condensateproof mouth mirror.
Accompanying drawing 1 is this utility model, the cross-sectional view of the little mirror of Condensateproof mouth mirror.
Accompanying drawing 2 is this utility model, Condensateproof mouth mirror heating line figure.
Glass substrate 1 is to use the water white transparency flat glass in the accompanying drawing 1.In glass substrate 1 front high-temperature chemical gas phase sediment layer of transparent Electric radiant Heating Film 2 as electric heating body; On Electric radiant Heating Film 2, make metal electrode 3 and metal lead wire 4; In glass substrate 1 back side vacuum evaporation layer of metal film 5 as the reflection of light film.
R in the accompanying drawing 2 is a transparent electric heating film, and E is heating power supply (1.5 to 3.0 volts), and available aneroid battery, W are potentiometers, and K is a switch.
The utility model has the advantages that by the electrical heating of minute surface hyaline membrane and reach antifog purpose. Mirror temperature is adjustable to be remained between 37 to 39 ℃, easy and simple to handle, and fast, reflected image is clear, has especially got rid of the alcolhol burner baking, has more outstanding advantages for the field rescue.
Claims (3)
1, a kind of Condensateproof mouth mirror of being made up of reflecting mirror and handle is characterized in that at the front of transparent glass substrate [1] chemical vapor deposition layer of metal oxide semiconductor electrically conducting transparent heating thin film [2]; At the back side of glass substrate vacuum evaporation layer of metal reflectance coating [5].
2, according to the described Condensateproof mouth mirror of claim 1, it is characterized in that on transparent electric heating film, making metal electrode and outer lead and power supply and join, and be provided with potentiometer switch adjusting heating power, keeping mirror temperature is 37 to 39 ℃.
