Specific embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, be respectively anti-outside provided by the invention haze eyeglass suitching type oral cavity doctor protectionMain view, rearview and the side view of mask comprising:
Protective plate 3 is made for transparent material (such as transparent plastic), has the shape being adapted with human body face, in this realityIt applies in example, in oval from the point of view of front；The protective plate 3 have one towards patient outer surface and one towards doctor faceInner surface；
Head hoop 8 in a ring and can adjust degree of enclosing, respectively pass through a rotary company with the two sides of the protective plate 3Fitting (such as pin or rivet) connects, and doctor can arrive suitable angle by rotation head hoop 8 when wearing protective face maskDegree obtains optimal wearing impression；
Adjustable eyeglass 4, is arranged on the outer surface of protective plate 3, by anti-feux rouges eyeglass with anti-blue light eyeglass in side by side up and downIt is stacked to form, it can be integral structure, can also be linked together by buckle, screw or glue；The two sides of adjustable eyeglass 4Respectively connect with a rack gear 11, the rack gear 11 vertical can be slidably arranged in the slideway 2 of 3 two sides of protective plate (referring toFig. 4)；
Two motors 9 are arranged near the slideway 2 of 3 two sides of protective plate, and can be operated synchronously by connection,Each motor 9 is connected with a gear (being unillustrated), and two gears respectively correspond with two rack gears 11 and engage connection；In this way,When two motors 9 operate synchronously, the translation of adjustable eyeglass 4 can be driven to rise or translation decline, thus control anti-feux rouges eyeglass orThe eye locations of anti-blue light eyeglass and doctor are adapted；
Haze outside protective plate 3 in order to prevent, be further fixed on the upside of the outer surface of the protective plate 3 one it is arc-shapedBlowing pipe 1, also there are gaps between the blowing pipe 1 and the protective plate 3, to allow the adjustable eyeglass 4 from gapIn pass through, slided up and down without influencing the adjustable eyeglass 4；There is the gas being arranged along its length in the blowing pipe 1Circulation road, and the both ends of blowing pipe 1 are respectively provided with the air inlet being connected with airflow channel, are respectively provided at the air inletOne Air Blast fan 6 dried to air inlet direction, is disposed with multiple air blowings directed downwardly between the both ends of the blowing pipe 1Hole (see Fig. 5), the gas hole are connected with the airflow channel.
Wherein, the motor 9 and Air Blast fan 6 are all connected with battery 10, and battery 10 is fixed on protective plate 3；?In alternative technical solution, the motor 9 can be connected to outer outside protective face mask with Air Blast fan 6 by supply linesConnect power supply.
In addition, the two sides of the protective plate 3 have also respectively protruded outward a reflecting optics 5, the reflecting optics 5 with it is describedIt is connected between protective plate 3 by universal joint, so as to the reflection angle of flexible modulation reflecting mirror.
Moreover, the lower edge of the protective plate 3 also evagination crimping and be formed with a groove 7, arranged in the groove 7There is one or two suction pipes (being unillustrated), the suction inlet of the suction pipe are arranged in the lower of groove 7, the suction pipe is along described recessedSlot 7 extends toward eminence and is connected to the suction pump outside protective face mask.
Oral cavity doctor before starting work, first has to the tightness that head hoop 8 is adjusted according to head size, then will protectionMask is worn on head, then adjusts the angle of protective plate 3 according to personal habits to obtain optimal visual impression.
When oral cavity doctor is that patient treats, examination of mouth first is carried out to patient, and do some pre-treatments, thenTherapeutic scheme is designed according to the concrete condition of patient.
During cavity preparation, oral cavity doctor needs to remove the softening in cavity by high speed turbo-drilling and sharp keen excavator spoonDentine can generate the impurity such as a large amount of steam, saliva, blood and tooth bits, but depositing due to protective plate 3 in this processDirt splash can completely cut off to the face of doctor, preventing cross-infection.But these impurity can be attached on protective plate 3, shadowAt this moment the operation sight for ringing doctor just needs to open air screen barrier: opening Air Blast fan 6, the air supply areas of Air Blast fan 6 is greater thanThe air inlet open area of blowing pipe 1, such air-flow a part enter blowing pipe 1 and spray again via gas hole, and another part existsIt is anteriorly sprayed under the action of Air Blast fan 6 by the rear portion of protective plate 3, gas flow figure is as shown in Figure 4.Across the portion of air screen barrierDivide steam that can be blown in the groove 7 of 3 lower part of protective plate, and because protective plate 3 tilts down, on protective plate 3Impurity also can along curved surface flow into groove 7 in, eventually by the suction guide in groove 7 to outside, so that impurity be avoided to fallIn the face of patient.
For needing dental body filled patient, after the completion of cavity preparation, need to carry out resin fill, oral cavity doctorNeed to complete this work by photo solidification machine, but photo solidification machine can issue dazzling blue light, this light is to doctor'sEyes be it is harmful, oral cavity doctor can be switched to the anti-blue light eyeglass that can isolate blue light by control motor 9 at this time, fromAnd it avoids by blue light illumination；And for needing to carry out physical therapy or carrying out the patient of operative treatment with laser knife, oral cavity doctor needsIt to be completed by laser therapeutic apparantus, laser therapeutic apparantus can generate during the work time has the red of intense radiation destruction to eyesLight, for such situation, oral cavity doctor can switch the anti-feux rouges eyeglass that can isolate laser by control motor 9, solveCertainly the problem of laser emission eyes.
In addition, in order to solve the problems, such as that photo solidification machine or laser therapeutic apparantus handle block oral cavity doctor's sight, oral cavity doctorLife can reach observation patient's cavity interior under the premise of not changing oneself head pose by adjusting the angle of reflecting optics 5The purpose of situation.
It is finally last handling process, oral cavity doctor can be processed by shot blasting dental surface, while clear up in patient oral cavityResidue, this process can also generate some fogs, but finally also can flow to outside by groove 7.
When oral cavity doctor complete entire therapeutic process after, need to unclamp head hoop 8 and remove protective face mask, to protective plate 3,Groove 7 and suction pipe are simply cleaned, and are then stored, in case next time uses.
By the above-mentioned course of work it is found that anti-outside of the invention hazes eyeglass suitching type oral cavity doctor's protective face mask, pass throughThe air screen barrier isolation method that outside setting blowing pipe and groove match is beneficial to prevent liquid and the tooth bits attachment of splashingCause mask to haze on mask and block sight, improves the convenience and safety when user's work；Cooperated using slideway 2The structure of Double spectacle lens can switch freely eyeglass according to the needs of use in the case where not needing to take eyeglass,Compared with the additional working method for wearing safety goggles of traditional needs, invention significantly improves the working efficiencies of doctor；FaceWhen 5 structure of reflecting optics on cover protective plate 3 can block in front of the doctor of oral cavity in the case where not changing head poseIt is operated by reflecting optics 5, avoids the fatigue when special sight angle works long hours；3 tilt angle of protective plate can phaseHead hoop 8 is freely arranged, is freely adjusted according to the usage requirement, comfort when oral cavity doctor work is improved.
