Embodiment 1

[0016] Example 1: figure 1 It is the overall schematic diagram of the present invention as a complete disposable dental mirror. It can be directly used for oral examination. The dental mirror is composed of a lens 1 , a mirror frame 2 and a handle 3 . Among them, lens 1 is to deposit a layer of hydrophilic material on the conventional mirror surface, so that the small water droplets in the fog formation process can form a thin water film on the mirror surface instead of dispersed micro-water droplets, so as to achieve anti-fog function. from image 3 The specific structure of the anti-fog reflector can be shown in the figure. Specifically, a layer of hydrophilic material layer 5 is deposited on a conventional ordinary reflector composed of ordinary silica glass 6 and reflective layer 7 .

Embodiment 2

[0017] Example 2: figure 2 It is used as a disposable front end of a multi-use oral mirror, and a connector 4 is added to the bottom of the handle, through which it can be connected to the rear end parts of the handle with different functions, or the rear end handle that can be reused many times, To integrate multiple functions on one dental mirror.

Abstract

The invention belongs to the field of medical apparatuses and instruments and particularly relates to an anti-mist mouth mirror. A lens is fixed in a mirror frame, and one end of the mirror frame is fixed on a hand shank. The surface of the lens is coated with a hydrophilic material layer capable of effectively preventing mist from forming. The hand shank and the mirror frame are made of common nontoxic materials. The anti-mist mouth mirror can be manufactured into a disposable mouth mirror to be used, and a connecting device can be added on the hand shank after the hand shank is shortened to be connected with the rear end of the multifunctional hand shank or serve as a disposable front end part of the mouth mirror capable of being used repeatedly so that various functions are integrated on the same mouth mirror.

Description

technical field [0001] The invention belongs to the technical field of oral medical equipment, and in particular relates to an anti-fog oral mirror. Background technique [0002] In the process of oral treatment, doctors often use oral mirrors to observe the situation inside the oral cavity. Especially in the process of diagnosis and treatment of teeth and oral surgery, oral mirrors play a key role in clearly identifying diseases and accurately treating them. But because the temperature in the oral cavity is higher than the temperature of the environment, and the environment in the oral cavity is humid, when the oral mirror is placed in the oral cavity, due to the above reasons, a layer of mist is often formed on the mirror surface of the oral mirror, which hinders the doctor from observing the oral cavity. Internal examination. [0003] Some of the existing oral mirrors are made of ordinary mirrors without anti-fog function, and some of them use the method of heating the ...
