The inventor of the application researches that the mouth mirror cannot avoid not contacting with water in the use process, and in order to normally observe the oral cavity of a patient through the lens in the use process, defogging is mostly carried out in a mode of coating on the surface of the lens, the defogging effect is poor, and the material research and development cost is high; the mouth mirror adopting the mode of externally adding the air source has simple structure, but the mouth gas flows repeatedly due to the hollow design of the knife handle, so that the mouth mirror is difficult to disinfect and clean; the manner of temperature regulation introduces additional temperature control equipment, increasing structural space and cost.
The application provides a stomatoscope and a preparation method thereof, which aim to solve the technical problems in the prior art.
The following describes the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems in detail with specific embodiments.
The present embodiment provides an stomatoscope 1 including: a lens 11 and a bracket 13.
The lens 11 includes: a first substrate 110 and at least two first hydrophobic structures 111.
The backlight side of the first substrate 110 is fixedly connected with the bracket 13.
At least the first hydrophobic structures 111 are arranged in an array, and are connected to the light facing side of the first substrate 110.
The at least one first hydrophobic structure 111 has a smaller size near the first substrate 110 than the first hydrophobic structure 111 has a smaller size far from the first substrate 110.
The inventors of the present application studied and found that in order to enable the stomatoscope 1 to have a defogging and hydrophobic effect, the lens 11 of the stomatoscope 1 itself can be treated so that the lens 11 is exposed to water without leaving water stains. The liquid can be suspended by the inverted suspension structure, so that the contact angle between the liquid and the inverted suspension structure is increased, and the hydrophobic effect is achieved.
In this embodiment, the lens 11 of the mouth mirror 1 achieves the anti-fog and hydrophobic effects through the first hydrophobic structure 111 on the lens 11, so that the cost is low, the whole structure of the mouth mirror 1 is simple, the mouth mirror is easy to use, the temperature control equipment with large occupied space is not needed, and the macroscopic structure is shown in fig. 1.
Optionally, the stomatoscope 1 provided in this embodiment can be used once, so that a disinfection procedure is omitted, and a problem of bacterial infection caused by difficulty in complete disinfection of the stomatoscope 1 is avoided. And the degree of defogging effect can be adjusted by changing the density of the array of first hydrophobic structures 111.
Alternatively, the bracket 13 may be made of a plastic material, so that the mouth mirror 1 is disposable, and cost is saved.
The inventors of the present application considered that a contact angle is generated when a liquid is in contact with the surface of an object, and that we consider hydrophilic when the contact angle is less than 90 °; less than 5 ° we consider super hydrophilic; when the contact angle is greater than 90 °, we consider the surface to be hydrophobic; particularly when the surface contact angle is greater than 150 °, it is referred to as superhydrophobic. To obtain the defogging effect, the super first hydrophobic structure 111 needs to be designed. The inverted microstructure can ensure that the liquid is suspended, so that the contact angle between the liquid and the microstructure is increased, and the hydrophobic effect is obtained. To this end, the present application provides the following one possible implementation for the lens 11 of the mouth mirror 1:
as shown in fig. 3, the first hydrophobic structure 111 of the lens 11 according to the embodiment of the present application includes: a first column 112 and a first cover 113.
One end of the first column 112 is connected to the light facing side of the first substrate 110, and the other end is connected to the first cover 113.
The radial dimension of the first cover 113 is at least greater than the radial dimension of the other end of the first cylinder 112.
The first hydrophobic structure 111 located on the light-facing side of the lens 11 in this embodiment includes a first column 112 and a first cover 113, where the radial dimension of the first cover 113 may be greater than the radial dimension of the first column 112, and the first column 112 is located between the first substrate 110 of the lens 11 and the first cover 113 of the first hydrophobic structure 111, so that the first cover 113 is an inverted suspension structure with respect to the first substrate 110, and may play a role in hydrophobic. That is, the lens 11 having a hydrophobic effect is used to provide the mouth mirror 1 with defogging and hydrophobic effects when in use. The present application provides the following methods for implementing the first hydrophobic structure 111:
in one embodiment, the first cover 113 includes: a first top 1131 and a first extension 1132.
The first top 1131 is connected to the other end of the first cylinder 112, and the radial dimension of the first top 1131 is at least greater than the radial dimension of the other end of the first cylinder 112.
The first extension 1132 is connected with an edge of the first top 1131, and the first extension 1132 extends toward the first substrate 110.
In this embodiment, in order to develop a hydrophobic surface with high contact angle, low adhesion and low flow resistance suitable for various liquids, the first cover 113 of the first hydrophobic structure 111 includes a first top 1131 and a first extension 1132. By the design of the first extension 1132, the first cover 113, such as a cap, covers the first column 112, and the first hydrophobic structure 111 is more delicate, so that the low surface energy liquid (i.e. the liquid difficult to adhere) can be effectively suspended without contacting the first substrate 110, and the lens 11 itself achieves the defogging and hydrophobic effects, as shown in fig. 2 for the embodiment.
Optionally, a ratio between the size of the first cover 113 of at least one first hydrophobic structure 111 and a distance between two adjacent first hydrophobic structures 111 is not less than 1:2 and not more than 3:5.
The inventors of the present application have found that, to achieve a better water-repellent effect, the ratio between the size of the first cover 113 of the first water-repellent structure 111 and the spacing between two adjacent first water-repellent structures 111 is 3:5.
Alternatively, the ratio of the size of the first cover 113 of the first hydrophobic structure 111 to the spacing between two adjacent first hydrophobic structures 111 is 1:2, which can also play a role in hydrophobic effect.
In the second implementation method, the radial dimension of the end of the first hydrophobic structure 111 near the light incident side is smaller than the radial dimension of the end far from the light incident side.
In this embodiment, by providing a plurality of inverted suspension structures capable of being hydrophobic, for example, inverted trapezoid, lower semicircle, etc. in cross section, for the radial dimensions of the two ends of the first hydrophobic structure 111, please refer to fig. 3, but the present invention is not limited to the shape provided in the drawings, and the irregular shape according to the present invention is also included.
In the third implementation method, the radial dimension of the end of the first hydrophobic structure 111 near the light incident side and the radial dimension of the end far from the light incident side are smaller than the radial dimension of the middle portion of the first hydrophobic structure 111.
In the above analysis, it has been mentioned that the inverted suspension structure can play a very good role in hydrophobic effect, and this embodiment provides a structure that can also increase the contact angle between the liquid and the surface to obtain a hydrophobic effect. Referring to fig. 4, the structure with small ends and large middle can suspend liquid, thereby achieving the effect of water repellency.
Based on the same inventive concept, the present application provides another mouth mirror 1 comprising: a lens 11, a hydrophobic membrane 12 and a support 13.
The hydrophobic film 12 includes: a second substrate 120 and at least two second hydrophobic structures 121.
At least two second hydrophobic structures 121 are arranged in an array and are each connected to one side of the second substrate 120.
The at least one second hydrophobic structure 121 has a smaller dimension proximate the second substrate 120 than the portion of the overhanging structure distal the first substrate 110.
The other side of the second substrate 120 is connected to the light-facing side of the lens 11.
The backlight side of the lens 11 is fixedly connected with the bracket 13.
In order to easily disinfect the stomatoscope 1 and reuse the lens 11 and the bracket 13, the embodiment provides a hydrophobic film 12, the hydrophobic film 12 can play a role of defogging and hydrophobic, then the hydrophobic film 12 is attached to the common lens 11, and the hydrophobic film 12 is made of transparent materials, so that the common lens 11 can defogging and hydrophobic under the cooperation of the transparent hydrophobic film 12 and can see the mirror image of the inside of the mouth cavity.
In this embodiment, referring to fig. 5, the macrostructure of the stomatoscope 1 is shown, and the light facing side of the lens 11 is attached with the hydrophobic film 12, so that the stomatoscope 1 can play an anti-fog and hydrophobic role while being used, and has the advantages of low cost, simple structure and easy use. Because the hydrophobic membrane 12 is attached to the lens 11, the hydrophobic membrane 12 is removed after the stomatoscope 1 is used, and then the rest of the structure of the stomatoscope 1 is sterilized, so that the sterilizing process is simplified. And the degree of defogging can be adjusted by the degree of the density of the array of the second hydrophobic structures 121.
Optionally, the other side of the second substrate 120 is connected to the light incident side of the lens 11, and the connection mode can be that the hydrophobic film 12 is bonded to the lens 11 by oxygen ion bonding, after the use, the mouth mirror 1 is put into an oxygen plasma machine to release the bonding, the hydrophobic film 12 is disposable, and the mouth mirror 1 with the bonding released can be directly sterilized by alcohol or sterilized at high temperature.
Alternatively, the hydrophobic film 12 may be made of glass or a flexible light-transmitting film material.
In one possible embodiment, the material of the hydrophobic film 12 is glass, and the dimensions of the hydrophobic film 12 are comparable to those of existing stomatoscope lenses. The material of the mouth mirror handle can be stainless steel. The hydrophobic membrane 12 may be a disposable material and the rest of the mouth mirror may be reusable. When the hydrophobic film 12 is needed, the hydrophobic film 12 and the stomatoscope without the hydrophobic film 12 are put into an oxygen plasma machine, and then the hydrophobic film 12 and the stomatoscope lens are pressed and bonded to obtain the stomatoscope with the hydrophobic film 12. When the use is finished, the hydrophobic film and the lens are only required to be de-bonded, wherein the de-bonding can be realized by heating, blowing and the like. The hydrophobic membrane 12 can be directly discarded as a disposable material, and then the stomatoscope body can be disinfected, so that the operation is convenient, the cost is low, and the defogging effect of the stomatoscope can be realized without complex structural improvement.
Alternatively, the holder 13 of the mouth mirror 1 is made of stainless steel material to improve the reuse rate.
In one possible embodiment, the second hydrophobic structure 121 includes: a second column 122 and a second cover 123.
One end of the second cylinder 122 is connected to one side of the second substrate 120, and the other end is connected to the second cover 123.
The radial dimension of the second cover 123 is at least greater than the radial dimension of the other end of the second cylinder 122. The specific implementation method can be seen in fig. 6.
In one possible embodiment, the second cover 123 includes: a second top 1231 and a second extension 1232.
The second top 1231 is connected to the other end of the second column 122, and the radial dimension of the second top 1231 is at least greater than the radial dimension of the other end of the second column 122.
The second extension 1232 is connected to an edge of the second top 1231, and the second extension 1232 extends toward the second substrate 120.
In one possible embodiment, the ratio between the size of the second cover 123 of at least one second hydrophobic structure 121 and the spacing between two adjacent second hydrophobic structures 121 is not less than 1:2 and not more than 3:5.
The second hydrophobic structure 121 in the above embodiments is identical to the first hydrophobic structure 111 of the lens 11 in the previous embodiments, and will not be described herein.
The second hydrophobic structure 121 provided in the foregoing embodiment can provide the lens 11 or the hydrophobic film 12 with defogging and hydrophobic effects, and the present embodiment provides a method for preparing the mouth mirror 1 to prepare the hydrophobic lens 11 or the hydrophobic film 12.
Based on the same inventive concept, the present application provides a method for preparing a mouth mirror 1, as shown in fig. 7, comprising steps S1-S4:
s1, depositing a first material layer 3 on a substrate 2, and patterning the first material layer 3 to obtain a first-state material structure 31.
Alternatively, the substrate 2 is glass. Since both the hydrophobic film 12 and the lens 11 have a hydrophobic structure, one set of preparation methods can be used in common, and the lens 11 or the hydrophobic film 12 having a hydrophobic structure can be obtained by changing the substrate 2. The substrate 2 can be selected to be a hydrophobic lens 11 or a hydrophobic film 12 according to actual conditions, and different materials are selected. For example, glass with a metal reflective film coated on one side can be used as the substrate 2 for preparing the lens 11, and transparent glass can be used for preparing the hydrophobic film 12.
In this step, the first material layer 3 is a material for preparing the first top 1131 of the first hydrophobic structure 111 or the second top 1231 of the second hydrophobic structure 121, and this step is an initial state before etching, the substrate 2 is selected, and then the first material layer is etched to prepare the first hydrophobic structure 111 or the second hydrophobic structure 121, and the structure obtained after step S1 is shown in fig. 8.
And S2, performing first etching on at least part of the substrate 2 which is not covered with the first-state material structure 31, so that the substrate 2 forms the first-state blind holes 21.
In this embodiment, after the first material layer 3 is patterned, some gaps are formed to expose a portion of the substrate 2. At least a portion of the substrate 2 not covered with the first state material structure 31 is subjected to a first etching, so that the substrate 2 forms the first state blind holes 21. The remaining first material layer 3 is the first state material structure 31, which is the first top 1131 of the first hydrophobic structure 111 or the second top 1231 of the second hydrophobic structure 121, and the structure obtained after the step S2 is shown in fig. 9.
Alternatively, the etching method may include, but is not limited to, dry etching and wet etching. Dry etching includes photo-evaporation, vapor phase etching, plasma etching, and the like. Wet etching is a purely chemical reaction process, which means that the etching purpose is achieved by removing the parts not masked by the masking film material by using a chemical reaction between the solution and the pre-etching material. Since the wet etching may etch away a part of the substrate 2 masked by the masking film, if the dry etching is used for the first etching, the thickness of the second etching is smaller than that of the first etching; if wet etching is used for the first etching, the thickness of the second etching may be equal to that of the first etching.
And S3, depositing a second material layer 4 on the first state material structure 31, on the substrate 2 and in the first state blind holes 21, and patterning the second material layer 4 to expose at least part of the substrate 2 at the bottom of the first state blind holes 21, thereby obtaining a second state material structure 41.
In this step, a second material layer 4 is deposited on the second state material structure 41 obtained in step S2, see fig. 10. And patterning the second material layer 4 until at least part of the substrate 2 at the bottom of the first state blind via 21 is exposed, and obtaining a second state material structure 41, see fig. 11.
Alternatively, when the second etching completely etches the corresponding second material layer 4 on the first state material structure 31, the second state material structure 41 may include the first state material structure 31 and the second material layer 4 perpendicular to the first state material structure 31.
Alternatively, when the second etching completely etches away the corresponding second material layer 4 on the first-state material structure 31 and a portion of the first-state material structure 31 is etched away, the second-state material structure 41 may include a portion of the first-state material structure 31 and the second material layer 4 perpendicular to the first-state material structure 31.
Alternatively, when the second etching does not etch the corresponding second material layer 4 on the first material structure 31, and only the second material layer 4 corresponding to the portion of the first blind via 21 is etched, the second material structure 41 may include the first material structure 31, the second material layer 4 covering the first material structure 31, and the second material layer 4 perpendicular to the first material structure 31.
Alternatively, when the second etching partially etches the corresponding second material layer 4 on the first state material structure 31, the second state material structure 41 may include the first state material structure 31, a portion of the second material layer 4 overlying the first state material structure 31, and the second material layer 4 perpendicular to the first state material structure 31.
In order to prepare the first extension 1132 or the third extension 1232, the structure obtained after the step S3 is shown in fig. 10.
And S4, performing second etching on at least part of the first-state blind holes 21 exposed out of the substrate 2, so that the first-state blind holes 21 form second-state blind holes 22, and obtaining the first hydrophobic structure 111 or the second hydrophobic structure 121. The second etching is wet etching.
In this step, at least part of the first blind holes 21 exposed in the substrate 2 obtained in step S3 is etched for the second time, so that the first blind holes 21 form second blind holes 22, and the first hydrophobic structure 111 or the second hydrophobic structure 121 is obtained. Since the etching is not one-directional etching, and needs to be performed in two directions, the second etching is wet etching.
In one possible embodiment, the depth of the first etch is less than the depth of the second etch.
Specifically, the first etching is to prepare the first extension 1132 or the third extension 1232, and the etching depth of the second etching needs to be greater than the first etching depth so as to be able to pass through the depth of the first extension 1132, thereby etching the substrate 2.
By applying the embodiment of the application, at least the following beneficial effects can be realized:
1. by preparing the lens 11 with the first hydrophobic structure 111, the lens 11 has defogging and hydrophobic effects, and has simple structure, easy operation and use, low space cost and mass production. Disposable, avoid the problem that the lens 11 is difficult to disinfect.
2. The hydrophobic membrane 12 with the second hydrophobic structure 121 is connected with the lens 11, so that the lens 11 achieves defogging and hydrophobic effects, has a simple structure, is easy to operate and use, has low space cost, and can be produced on a large scale. The hydrophobic membrane 12 is disposable, so that the problem that the hydrophobic structure is difficult to disinfect is avoided, and the stomatoscope 1 with the hydrophobic membrane 12 removed is directly disinfected in the later stage.
