[0043] In order to make the person skilled in the art better understand the present application, the present application is further described in detail below in combination with the drawings and specific embodiments.

[0044] The portable diagnostic system in this embodiment includes a sample collection component, a sample carrying component, a reflective structure, a carrying bracket, a lifting dial, and an imaging device. In this embodiment, the portable diagnostic system is specifically used to examine eyelashes to check for the presence of Demodex mite pathogens, and then to determine whether Demodex blepharitis is present.

[0045] The prerequisite for examination is obtaining an eyelash sample; therefore, the portable examination system in this embodiment includes a sample collection component. Please refer to [link / reference needed]. Figures 1-3 , Figure 1 This is a schematic diagram of the sample collection component 1 of the portable diagnostic system in this embodiment; Figure 2 for Figure 1 A schematic diagram of the protruding teeth 122 and the grooves 121 of the sample acquisition component 1; Figure 3 for Figure 1 Front view of the clamping end 12.

[0046] The sample collection component 1 includes tweezers, which have two gripping parts. Each gripping part includes a handle 11 and a first end and a second end located at both ends of the handle 11. The first ends of the two handles 11 are connected, and the second ends are separated from each other. The second ends are gripping ends 12, and the two gripping ends 12 can be brought close together to grip the eyelash to be clamped. Depending on the examination needs, one or more eyelashes can be randomly clamped.

[0047] To obtain eyelash samples more reliably, such as Figure 2 , 3 As shown, one clamping end 12 of the sample acquisition component 1 is provided with a protruding tooth 122, and the other clamping end 12 is provided with a toothed groove 121. The protruding tooth 122 can be inserted into the toothed groove 121 to achieve coupling. Figure 2 In this design, the protruding teeth 122 have trapezoidal tips, and the grooves 121 are matching trapezoids. This facilitates the eyelash entering the grooves 121 and being clamped by the protruding teeth 122. Of course, the grooves 121 and protruding teeth 122 can also be configured with other matching shapes for easy clamping. A set of matching protruding teeth 122 and grooves 121 forms a clamping unit that can be used to hold a single eyelash. Figure 3 The embodiment has three sets of protruding teeth 122 and tooth grooves 121, which can hold three eyelashes at the same time. Of course, each set of protruding teeth 122 and tooth grooves 121 can also be used to hold more than one eyelash. This embodiment does not limit this.

[0048] Furthermore, in this embodiment, the clamping end 12 of the sample collection component 1 has an annular structure, forming a window 12a. This facilitates observation of the number of eyelashes being clamped and also makes it easier to transfer the eyelashes to the sample carrying component 2 described below. Additionally, the distal end of the clamping end 12 can be set as a blunt structure, i.e., not a sharp shape. This avoids piercing the eyelid during operation and reduces the patient's fear. Figure 1As shown, the clamping end 12 is substantially annular, and the clamping end 12 has a portion away from the first end, which is a straight segment, that is, the clamping end is an annular structure formed by an arc segment greater than 180 degrees and a straight segment.

[0049] The above is the specific structure of the sample collection component 1. It can be known that the sample collection component 1 is not limited thereto. For example, the sample collection component 1 can be a conventional tweezers structure, that is, the clamping end 12 is a pointed end or a flat end, etc.

[0050] Please continue to refer to Figures 4-6 , Figure 4 is a schematic view of the sample bearing component 2 of the portable diagnosis system in the embodiment; Figure 5 is a schematic view of the sample bearing component 2 in which the collected eyelash A is placed; Figure 4

[0051] Figure 6 is a schematic view of the flexible bearing 22 of the sample bearing component 2 in Figure 5 being flattened.

[0052] As shown in Figure 4 , 5 , the sample bearing component 2 includes a glass slide 21, and the glass slide 21 is provided with a flexible bearing 22, which forms a containing cavity or is surrounded by the glass slide 21 to form a containing cavity. The collected eyelash A sample can be placed in the containing cavity, so that the light eyelash can be kept in a relatively stable position to avoid displacement and drifting away during shooting. The flexible bearing 22 is made of a flexible transparent material to realize subsequent shooting of the contained eyelash. The flexible bearing 22 can be arranged at the central position of the glass slide 21 or other set positions, which is beneficial to the focusing of the lens of the subsequent shooting device 34. Figure 4 In , the flexible bearing 22 is conical, and the large end thereof is the opening end of the containing cavity, so as to facilitate the introduction of the eyelash A into the containing cavity.

[0053] In addition, the sample bearing component 2 further includes a flattening piece, which is specifically Figure 4 as shown in Figure 5As shown, the flexible carrier 22 is pulled to be flat by the adhesive paper 23, and the eyelashes A in the flexible carrier 22 can be flattened and fixed, which is more conducive to the stability of the position of the eyelashes A and the shooting. Before the eyelashes A are placed, a liquid such as alcohol can be dropped into the accommodating cavity of the flexible carrier 22, so that the Demodex mites in the hair follicles of the eyelashes A can be stimulated to move out and be observed. It can be seen that the flattening member is not limited to the adhesive paper 23. For example, the flattening member is a pressing plate, the eyelashes A are placed in the flexible carrier 22 of the glass slide 21, and the glass slide 21 is pressed by the pressing plate to realize flattening.

[0054] It should be noted that the portable diagnosis system does not necessarily include the sample collection component 1 and the sample carrier component 2. For example, the sample of the eyelashes A can be obtained by other means, which can be other tools or directly manually obtained; the eyelashes A can be directly placed in the diagnosis device 3 for shooting, that is, the sample carrier component is arranged in the diagnosis device 3 (such as being connected or integrally formed with the base 342 of the diagnosis device 2, or the carrier support 32 serving as the sample carrier component, etc.), without the need for a separate sample carrier component 2. The separately arranged sample carrier component 2 in the embodiment can more conveniently fix the eyelashes A.

[0055] After the sample collection and carrying are completed, the sample carrier component 2 can be placed in the diagnosis device 3 of the portable diagnosis system for diagnosis. Please continue to refer to Figure 7 、 8 , Figure 7 FIG. 16 is a schematic view of the carrier support 32 and the light reflection structure 31 of the diagnosis device 3 in the portable diagnosis system in the embodiment; Figure 8 Figure 7 FIG. 16 is a schematic view of the carrier support 32 and the light reflection structure 31 of the diagnosis device 3 in the portable diagnosis system in the embodiment;

[0056] The sample carrier component 2 described above can be placed on the carrier support 32, and the carrier support 32 specifically includes a carrier plate 321 provided with a through hole 321a. The flexible carrier 22 of the sample carrier component 2 can be placed in alignment with the position of the through hole 321a, and the shooting device 34 described above is located below the position of the through hole 321a, which is convenient for shooting the eyelashes A in the flexible carrier 22. Of course, when the carrier plate 321 is made of a transparent material, the through hole 321a can not be arranged, but the arrangement of the through hole 321a has the least influence on the shooting.

[0057] ​The light reflection structure 31 comprises a light reflection plate 311 for reflecting light, which is conducive to obtaining a clear shooting image. Specifically, the light reflection plate 311 is in a disc-shaped structure, and in the working state, it is located above the sample bearing component 2. The disc-shaped light reflection plate 311 is convex in the direction away from the sample bearing component 2, and the light reflection plate 311 comprises a main body part 311a and an annular edge part 311b surrounding the main body part 311a. The inner side surface of the main body part 311a is black, that is, it can be coated with a black coating on the inner side surface, or the entire main body part 311a can be made of black material to form a black non-reflective part. The inner side surface of the annular edge part 311b is white, that is, it is coated with a white light reflection coating on the inner side surface or is made of white material as a whole to form a diffuse reflection part.

[0058] As shown in Figure 9 , Figure 9 , Figure 8 is a schematic diagram of the working principle of the light reflection structure 31 in the embodiment.

[0059] When the sample bearing component 2 is placed on the bearing support 32, the light reflection plate 311 is located above the sample bearing component 2, and the light source is arranged below the bearing support 32. The LED light column 342a serving as the light source irradiates the white annular edge part 311b, thereby reflecting the light around the sample bearing component 2 to the middle position of the sample bearing component 2 where the eyelash A sample is arranged, while the main body part 311a of the light reflection plate 311 does not reflect light. In this way, high-contrast observation and shooting under dark field can be achieved.

[0060] Please continue to see Figure 7 , 8 , the light reflection structure 31 in the embodiment further comprises a connecting frame 312, and the light reflection plate 311 is connected to one side of the bearing plate 321 of the bearing support 32 through the connecting frame 312. The connecting frame 312 comprises a fixed rod 312a and a movable rod 312b. The fixed rod 312a is fixed to the bearing support 32 and extends upward, and the movable rod 312b is rotationally connected to the fixed rod 312a. The movable rod 312b is fixedly connected to the light reflection plate 311, and the light reflection structure 31 and the bearing support 32 are assembled to form a support light reflection plate assembly. In this way, before placing the sample bearing component 2, the light reflection plate 311 can be flipped away from the bearing support 32, which is convenient for placing the sample bearing component 2. After the sample is placed, the light reflection plate 311 can be flipped above the sample bearing component 2. The rotationally connected movable rod 312b and fixed rod 312a can be provided with a limiting part to prevent the movable rod 312b and the fixed rod 312a from swinging in the working state. It can be seen that such arrangement is convenient for adjusting the position of the light reflection plate 311, which is conducive to the placement of the sample and the adjustment of the light, but the light reflection plate 311 can also be fixedly arranged relative to the bearing plate 321.

[0061] Please continue to combineFigure 8 Referring to Figures 10-12 , Figure 10 is a schematic view of the support reflector plate assembly, the lifting dial 33, and the camera device 34 mounted to the back of the camera device 34 of the diagnosis device 3 of the portable diagnosis system in this embodiment; Figure 11 is Figure 10 is a schematic view of the assembly of the support reflector plate assembly, the lifting dial 33, and the camera device 34 in this embodiment; Figure 12 is Figure 11 is a schematic view of the assembly of the lifting dial 33 and the camera device 34 in this embodiment.

[0062] As shown in Figure 12 , the camera device 34 includes a base 341 and a camera 342, and a receiving groove 341a is arranged in the middle of the base 341, and an annular cavity 34s is formed between the camera 342 and the side wall of the receiving groove 341a. As shown in Figure 8 , the bottom of the support 32 is provided with a first threaded tube 322, the outer peripheral wall of the first threaded tube 322 is provided with external threads, and the diameter of the tube cavity of the first threaded tube 322 is the same as or greater than the diameter of the through hole 321a. When assembled, the first threaded tube 322 can be inserted into the annular cavity 34s of the camera device 34 described above.

[0063] In addition, as shown in Figure 12 , the portable diagnosis system further includes a lifting dial 33, and the lifting dial 33 includes a second threaded tube 331, and the inner side wall of the second threaded tube 331 is provided with internal threads, which are matched with the external threads of the first threaded tube 322 at the bottom of the support 32 described above. The top of the second threaded tube 331 of the lifting dial 33 extends radially outward to form an annular flange 332, and when assembled, the lifting dial 33 is first sleeved on the first threaded tube 322, and then the first threaded tube 322 of the support 32 and the second threaded tube 331 of the lifting dial 33 are inserted into the annular cavity 34s of the camera device 34 together, and the annular flange 332 of the lifting dial 33 is located above the annular cavity 34s, the outer diameter of the annular flange 332 is greater than the outer diameter of the annular cavity 34s, and the annular flange 332 will not fall into the annular cavity 34s, as shown in Figure 11 , the annular flange 332 is supported on the upper end face of the base 341.

[0064] As shown in Figure 8 , the inner side wall of the first threaded tube 322 of the support 32 is provided with a limiting strip 322a protruding inwardly, and as shown in Figure 12As shown, the side wall of the camera 342 located in the base 341 accommodating groove 341a is provided with a limiting groove 342b, and the limiting strip 322a and the limiting groove 342b both extend in the axial direction, that is, the axial direction of the first threaded tube 322, the second threaded tube 331 and the annular cavity 34s, which are coaxially installed. Thus, when the support reflector plate assembly and the lifting dial 33 are assembled to the shooting device 34, the annular flange 332 of the lifting dial 33 can be rotated to rotate the lifting dial 33. Since the lifting dial 33 is threadedly connected with the first threaded tube 322 and is limited by the limiting strip 322a and the limiting groove 342b, the support reflector plate assembly cannot be rotated and can only be lifted in the axial direction, so that the sample on the glass slide 21 and the camera lens 342c of the camera 342 can be focused according to the needs.

[0065] In this embodiment, the second threaded tube 331 of the lifting dial 33 and the first threaded tube 321 at the bottom of the carrier 32 are threadedly connected, thereby driving the sample carrier 2 placed on the carrier plate 321 to be lifted. The lifting component is obviously not limited to the combination structure of the first threaded tube 322 and the second threaded tube 331, but can also be other forms to realize lifting, such as a screw nut transmission pair or a rack transmission pair. Here, the first threaded tube 322 and the second threaded tube 331 are arranged around the sample (arranged around the through hole 321a, that is, arranged around the sample), and the camera 342 is arranged, so that the shooting is not interfered on one hand, and the structure arranged around is more stable on the other hand.

[0066] Figure 12 In this embodiment, the camera 342 includes a camera lens 342c located in the middle and a housing accommodating the camera lens 342c. The camera lens 342c can have a magnification of about 100. The camera lens 342c can be a fine adjustment focusing lens or a fixed focus lens. The limiting groove 342b can be arranged on the outer side wall of the housing, and the annular cavity 34s is formed between the housing of the camera 342 and the accommodating groove 341a. It can be seen that the housing is provided with the limiting strip 322a, and the inner side wall of the first threaded tube 322 is provided with the limiting groove 342b, which can also achieve the purpose of limiting the rotation of the first threaded tube 322. Alternatively, the limiting groove 342b or the limiting strip 322a can be arranged on the side wall of the accommodating groove 341a of the base 341, which is also a feasible scheme as long as the first threaded tube 322 can be limited from rotating with the lifting dial 33.

[0067] In addition, the edge of the annular flange 332 of the rotating disc 33 can be provided with a rotating protrusion 333, and a plurality of rotating protrusions 333 are distributed along the edge of the annular flange 332 in the circumferential direction. The rotating protrusion 333 is provided to facilitate force application. It can be understood that the rotating disc 33 does not move axially, and the rotating disc 33 can be pressed when rotating, or a rotating stopper is arranged on the base 341 to limit the axial movement of the rotating disc 33. When the rotating disc 33 is inserted into the annular cavity 34s, the rotating stopper is rotated to the upper side of the rotating disc 33, thereby limiting the axial movement. There are various ways to achieve axial positioning, and the embodiment will not be described again.

[0068] In addition, the camera 342 in the embodiment also includes an image acquisition module, and a light source for providing light to the sample. The light source can be a ring-shaped LED light bead 342a arranged around the camera lens 342c. The light source can be provided with a separate power supply component, or can be externally powered. For example, the power supply can be connected through the OTG interface of the mobile phone. The camera 342 also includes an image calculation module, and the image transmission module can be an OTG / WIFI transmission module. The image acquisition module can transmit the collected image to a smart terminal such as a smart phone terminal or a computer terminal through the image transmission module. The smart phone terminal or the computer terminal can be used as a monitor to realize real-time display observation or photograph storage.

[0069] As can be seen, after collecting the sample on site, the portable diagnosis system provided in the embodiment provides light through the light source, and reflects the light through the reflector to provide sufficient shooting light, and then the camera 342 is used to shoot the sample, so that an image meeting the diagnosis clarity requirement can be shot. Specifically, an enlarged image can be directly shot, or can be enlarged and displayed on the smart terminal, so that whether the eyelash A has the demodex pathogen can be observed from the smart terminal without the need for microscope observation. The checking device and the checking process are relatively simple, which is beneficial to realize clinical rapid diagnosis, or the user can also realize self-checking without the need for steps such as sampling and microscope examination in the hospital, thereby saving time and facilitating timely detection of the disease.

[0070] It can be seen that the portable diagnosis system takes detecting whether the eyelash has the demodex pathogen as an example, but obviously, other diseases can also be detected. For example, a tear sample can be collected and diagnosed through shooting to assist in diagnosing dry eye. Of course, the diagnosis is not limited to ophthalmology, and the diagnosis of other parts can also be applied. For example, dandruff, hair, and nail samples can be obtained and diagnosed through the portable diagnosis system of the embodiment.

[0071] The principles and implementations of the present application are described in the specific examples in this article, and the above examples are only used to help understand the method of the present application and its core idea. It should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, the present application can be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
