When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0036] The present utility model provides a cataract detection device 100, which can be used to detect the eyes of a detector to obtain the eye image information of the detector, so as to judge the eye condition of the detector according to the image information and timely understand the eye condition.

[0037] Specifically, please refer to Figures 1 to 3, in this embodiment, the cataract detection device 100 includes a housing 1, a front-end component 2, and a supplementary lighting component 3. Among them, a detection port is provided at the front end of the housing 1; the front-end component 2 is covered at the detection port and forms a detection window protruding from the housing 1; the supplementary lighting component 3 is arranged in a ring around the periphery of the detection window, and the emitted light is suitable for irradiating the human eye located within the detection window.

[0038] It should be noted that, as shown in Figure 1 , when the cataract detection device 100 is in normal use, the end of the cataract detection device 100 facing the detector is the front, and the end facing away from the detector is the back. Therefore, when the cataract detection device 100 is in normal use, the detection port is arranged facing the detector, so that during detection, the detector's eye can be aligned with the detection port, and the eye image information of the detector can be obtained through the detection port.

[0039] In this embodiment, by providing a detection port at the front end of the housing 1, the imaging component inside the cataract detection device 100 can obtain the eye image information of the detector through the detection port; by the front-end component 2 to define a detection window, the detector can place a single eye within the detection window during detection, so that the eye can be closer to and aligned with the detection port, so that the imaging component can better obtain the eye image information; by providing a supplementary lighting component 3 at the detection window, the supplementary lighting component 3 can illuminate the human eye located within the detection window, making the obtained eye image information clearer. Moreover, the supplementary lighting component 3 is arranged in a ring around the periphery of the detection window, so that all parts around the eye can be evenly illuminated, and there will be no light spots in the local area of the eye pupil or the human eye iris, resulting in affecting the judgment of the detection result, making the detection image clearer and the detection result more accurate and reliable.

[0040] Among them, the supplementary lighting component 3 should make the light irradiated on the eye be evenly distributed, and the light emitted by the supplementary lighting component 3 is not reflected back to the imaging component inside the cataract detection device 100 through the human eye iris or pupil, so that the imaging component cannot capture the illumination light, making the image clearer and ensuring the accuracy of the detection result. Moreover, if the distance between the supplementary lighting component and the eye located within the detection window is too close, the light emitted by the supplementary lighting component will be reflected to the imaging component through the human eye iris or pupil, so that the image information obtained by the imaging component will have an image of the illumination light, resulting in the eye image information not being pure, which will affect the judgment of the eye condition.

[0041] Therefore, preferably, as shown in Figure 2 and Figure 3As shown, the supplementary lighting component 3 includes a supplementary light strip 31 and a light homogenizing member 32. The detection window is arranged in a substantially cylindrical shape, having an opening facing forward for the examiner's eyes to be placed into the detection window through the opening. The other end of the detection window faces the detection port, so that the imaging component in the cataract detection device 100 can obtain the eye image information in the detection window from the detection port. Moreover, the supplementary light strip 31 is arranged in a ring shape and sleeved on the inner peripheral side of the detection port of the housing 1. The illumination light emitted by the supplementary light strip 31 can surround the periphery of the detection window, ensuring more uniform illumination at various parts of the eye in the detection window, and thus achieving a better lighting effect. Moreover, the supplementary light strip 31 is arranged closer to the peripheral side wall of the detection window and farther away from the shooting area of the imaging component, so that the imaging component does not directly shoot the supplementary light strip 31, ensuring that the obtained image information is more accurate. Moreover, the light homogenizing member 32 is also arranged in a ring shape and is arranged on the inner peripheral side of the supplementary light strip 31. The light homogenizing member 32 is located on the inner peripheral side of the detection window. Through the light homogenizing member 32, the light emitted by the supplementary light strip 31 can be conducted, so that after being conducted by the light homogenizing member 32, the light can be emitted more evenly, and thus the light can illuminate the eye more softly and evenly, without showing local light spots in the iris or pupil of the human eye. The eye image information obtained by the cataract detection device 100 is clearer, which is beneficial for medical staff to make judgments and improves the detection efficiency and detection quality.

[0042] Among them, the supplementary light strip 31 has a plurality of LED lights, and the plurality of LED lights are distributed at intervals along the circumferential direction of the detection port to be evenly arranged on the inner side of the detection window, ensuring the uniformity of light.

[0043] Of course, in other embodiments, a plurality of lighting lamps can also be arranged on the inner peripheral side of the detection window. By evenly arranging the plurality of lighting lamps on the inner side of the detection window, the light in the detection window is made uniform and soft. Obviously, the arrangement of the supplementary light strip 31 can make the structure simpler and easier to replace and install.

[0044] Further, to facilitate the disassembly, assembly, and maintenance of the supplementary lighting component 3. The housing 1 includes a housing main body 11 and an extension section 12 protruding from the front side of the housing main body 11. The detection port is provided on the extension section 12 and communicates with the inner cavity of the housing main body 11. The extension section 12 is used to connect with the front-end component 2, so as to facilitate the alignment of the user's eyes with the detection port. Moreover, an installation part 13 is provided on the inner ring side of the extension section 12. The installation part 13 is arranged close to the front end of the extension section 12. The supplementary light strip 31 is connected to the installation part 13. Through the installation part 13, the supplementary light strip 31 can be preliminarily restricted at the front end of the extension section 12, so that the supplementary light strip 31 can be closer to the human eye, and thus the lighting effect on the eyes is better.

[0045] Specifically, as shown in combination with Figure 2 and Figure 4 , the installation part 13 includes an annular protrusion 131 provided on the inner side of the extension section 12. A gap is formed between the annular protrusion 131 and the inner side wall of the extension section 12. The supplementary light strip 31 is sleeved in the gap. Through the gap, the annular light strip is limited, so that the supplementary light strip 31 can be closer to the inner side wall of the extension section 12, and the camera component is prevented from acquiring an image of the supplementary light strip 31. Moreover, through holes are provided on the annular protrusion 131. The light emitted by the supplementary light strip 31 can irradiate towards the human eye located within the detection window through the through holes, so as to ensure that the supplementary light strip 31 can be better fixed at the port close to the detection window, and at the same time, the light is not blocked, and the light brightness is better when irradiating on the human eye, so that the acquired eye image information is clearer.

[0046] Further, one end of the annular protrusion 131 along the axial direction of the detection port is connected to the extension section 12, and the other end of the annular protrusion 131 along the axial direction of the detection port is open to the extension section 12, that is, the annular protrusion 131 and the extension section 12 are generally in a "U" shape, and the connection end of the annular protrusion 131 and the extension section 12 is arranged close to the front end of the detection window. Therefore, the supplementary light strip 31 can be sleeved into the gap from the open end of the annular protrusion 131 and the extension section 12, so as to clamp and fix the supplementary light strip 31 jointly by the annular protrusion 131 and the extension section 12, facilitating the disassembly, assembly, and maintenance of the supplementary light strip 31.

[0047] Moreover, the supplementary light strip 31 can be further restricted at the open end of the annular protrusion 131 and the extension section 12 to prevent the supplementary light strip 31 from coming off. Specifically, as shown in combination with Figure 2 and Figure 3As shown, the front-end component 2 includes a pressing member 21, an end cap 22, and a shielding cover 23. The pressing member 21 is sleeved on the inner ring side of the extension section 12 and is located at the open end of the annular protrusion 131 and the extension section 12. The pressing member 21 abuts against the end of the supplementary light strip 31 to completely confine the supplementary light strip 31 within the gap between the annular protrusion 131 and the extension section 12. The end cap 22 is sleeved at the detection port and abuts against one end of the light homogenizing member 32 along the axial direction of the detection port. The housing 1 abuts against the other end of the light homogenizing member 32 along the axial direction of the detection port. The end cap 22 and the extension section 12 jointly clamp both sides of the light homogenizing member 32 along the axial direction to fix the light homogenizing member 32. The shielding cover 23 is disposed inside the extension section 12 and is configured to block the detection port. The shielding cover 23 is provided with a first through hole 231. The shielding cover 23 blocks the detection port to achieve a better sealing effect, and through the first through hole 231, the imaging component can obtain the image information of the eye within the detection window.

[0048] In addition, the housing 1 further includes a protective cover 15 disposed on the inner ring side of the extension section 12. The cover opening of the protective cover 15 is connected to the annular protrusion 131. The protective cover 15 is recessed towards the inside of the housing body 11 and is spaced apart from the extension section 12. The protective cover 15 is provided with a second through hole 151. The second through hole 151 and the first through hole 231 are disposed opposite to each other. The imaging component can obtain the eye image information through the second through hole 151 and the first through hole 231.

[0049] Moreover, the front-end component 2 further includes a protective glass 24. The protective glass 24 is disposed at the second through hole 151 and is configured to block the second through hole 151. While allowing light to penetrate through the protective glass 24, the housing 1 is enclosed to better protect other components inside the housing 1.

[0050] Wherein, the shielding cover 23 is located in front of the protective cover 15, and the shape of the shielding cover 23 is adapted to the shape of the protective cover 15, so that the shielding cover 23 can fit more closely to the protective cover 15, making the structure more compact.

[0051] In one embodiment, in combination with Figure 2 and Figure 4As shown, a positioning portion 211 is further provided on one side of the pressing member 21, and a mating portion cooperating with the positioning portion 211 is provided on the extension section 12. Through the cooperation of the positioning portion 211 and the mating portion, the pressing member 21 and the extension section 12 are butted against each other to restrict the relative rotation of the pressing member 21 and the extension section 12 in the circumferential direction, so that the pressing member 21 can be quickly positioned.

[0052] The pressing member 21 is generally arranged in an annular shape. Preferably, the positioning portion 211 is arranged as a positioning protrusion 2111, and the positioning protrusion 2111 is arranged at the rear end of the pressing member 21 and extends axially backward along the pressing member 21; the mating portion is arranged as a positioning hole on the extension section 12. By inserting the positioning protrusion 2111 into the positioning hole, the pressing member 21 cannot rotate relative to the extension section 12, and at the same time, the pressing member 21 and the extension section 12 can be quickly positioned to prevent misoperation and ensure the correct installation of the pressing member 21.

[0053] Moreover, a fixing portion is further provided at the rear end of the pressing member 21. The fixing portion is provided with a first mounting hole, and a second mounting hole is provided at the rear side of the protective cover 15. The pressing member 21 and the protective cover 15 are connected and fixed by a connecting member passing through the first mounting hole and the second mounting hole, so as to completely fix the pressing member 21 on the housing 1.

[0054] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structures made by using the description and drawings of the present invention, directly or indirectly applied to other related technical fields, are equally included in the patent protection scope of the present invention.
