Abstract
The utility model belongs to the field of medical equipment, and relates to an antifogging mouth speculum. According to the antifogging mouth speculum, a lens is fixed in a speculum frame; one end of the speculum frame is fixed to a handle; a hydrophilic material layer is coated on the surface of the lens to prevent the formation of fog effectively; and the handle and the speculum frame are made of ordinary non-toxic plastics. The mouth speculum can be used as a complete disposable mouth speculum; and a connector can be arranged on a shortened handle to be connected to the rear end of the multifunctional handle, or can be used as a disposable front end part for the mouth speculum which can be used for multiple times to ensure that multiple functions are integrated on the same mouth speculum.
Description
Technical field
This utility model belongs to the oral medical equipment technical field, is specifically related to a kind of antifog dental mirror.
Background technology
In the process of dental care, the doctor often will be through the situation of using dental mirror to come observation panel intracavity portion.Particularly in the process to the diagnosis and treatment of tooth and operation on oral cavity, what will be clear that distinguishes disease and accurately imposes treatment that dental mirror plays a part crucial.But because intraoral temperature is higher than the temperature of environment, and environment is moistening in the oral cavity, when being put in dental mirror in the oral cavity, owing to above reason, tends on the mirror surface of dental mirror, form fumulus, hinders the examination of doctor's boil on the nape opposite the mouth intracavity portion.
Existing dental mirror, the common minute surface of the employing that has are processed and are not had an anti-fog function, and the employing that has is to the mode of minute surface heating, mirror temperature is equaled or a little more than oral temperature to place the generation of fog.This antifog method is owing to want additional power source, uses inconvenience and cost is higher.
Summary of the invention
The purpose of this utility model is to provide a kind of antifog dental mirror.
The antifog dental mirror that this utility model proposes is made up of eyeglass 1, picture frame 2 and handle 3; Eyeglass 1 is fixed in the picture frame 2, and picture frame 2 one ends are fixed on the handle 3; Be coated with hydrophilic material layer 5 on the minute surface of eyeglass 1.
In this utility model, handle 3 ends are provided with adapter 4, are used to connect the handle rear end of difference in functionality.
In this utility model, eyeglass 1 is formed by stacking by general silica glass 6 and reflecting layer 7.
In this utility model, said hydrophilic material layer 5 is made up of the hydrophilic polymer thin film, as is doped with CeO
2, SnO
2Or the TiO of La
2Thin film.
This utility model is employed in deposit one deck absorbent material on the conventional minute surface from specular material.Contact angle between little water droplet and this material is below 20 ° (when adopting more the strongly hydrophilic material; Can reach 0 °); Make the little water droplet in the fog forming process form very thin water film of one deck in mirror surface, rather than dispersive miniature water droplet form, thereby reach antifog effect.Simultaneously can be made into complete disposable oral cavity mirror, or add adapter, connect the handle rear end of difference in functionality at handle portion according to different needs, or as the disposable front end component that repeatedly uses dental mirror.
The beneficial effect of this utility model is: the patient is carried out in the process of examination of mouth the doctor; Can effectively reduce because the formation of the fog that the temperature difference between inside, oral cavity and the minute surface causes, improve the definition of mirror image and need not additional power source minute surface is heated.Make it both have antifog function and get simultaneously, reduced power pack than tradition through the dental mirror that mode of heating reaches anti-fog function again, structure is simpler, and is easy to use.In addition, because it need not external power source, so can it be made disposable front end component, its rear end can connect other functional parts, on a dental mirror, realizes the multiformity of function of use.
Description of drawings
Fig. 1 is the overall schematic as the antifog dental mirror of complete dental mirror.
Fig. 2 is as the sketch map that is repeatedly used the disposable use front end in the dental mirror.
Fig. 3 is reflecting mirror and picture frame section and mirror structure sketch map.
Label among the figure: 1 is eyeglass, and 2 is picture frame, and 3 is handle, and 4 is adapter, and 5 is the hydrophilic material layer, and 6 is general silica glass, and 7 is the reflecting layer.
The specific embodiment
Combine accompanying drawing to further specify this utility model through embodiment below
.
Embodiment 1: Fig. 1 is the overall schematic of this utility model as complete disposable oral cavity mirror.Availablely directly be used for carrying out examination of mouth.This dental mirror is made up of eyeglass 1, picture frame 2 and handle 3.Wherein, eyeglass 1 is deposit one deck hydrophilic material on conventional minute surface, makes the little water droplet of fog forming process can on minute surface, form the very thin moisture film of one deck, rather than dispersive miniature water droplet form, thereby reaches antifog function.From Fig. 3, can go out the concrete structure of this antifog reflecting mirror.Be specially at one deck hydrophilic material layer 5 that constituted on the conventional normal mirror deposit by general silica glass 6 and reflecting layer 7.
Embodiment 2: Fig. 2 is as the disposable use front end that repeatedly uses dental mirror; Added an adapter 4 in the handle bottom; Can be connected to through this adapter; Handle rear end parts with difference in functionality, the rear end handle that maybe can be repeatedly used is with integrated multiple function on a dental mirror.
