[0002] Due to environmental pollution and the popularity of mobile electronic devices, the incidence of dry eye syndrome is increasing year by year. Dry eye syndrome refers to a variety of diseases characterized by decreased tear film stability caused by abnormal tear quality and quantity or abnormal dynamics due to any reason, accompanied by eye discomfort and ocular surface tissue lesions. It is also called keratoconjunctivitis sicca. Its common symptoms include dry eyes, easy fatigue, itchy eyes, foreign body sensation, painful burning sensation, sticky secretions, fear of wind, fear of light, sensitivity to external stimuli, etc.

[0003] The demand for the diagnosis of dry eye in clinical practice is very huge. Existing methods for checking dry eyes generally include contact and non-contact methods. The contact method generally refers to the tear film secretion test method. This method requires the test paper to be placed in the conjunctival sac of the human eye, which is easy to cause discomfort to the person being tested, and people with other eye diseases are often not suitable for this method. Non-contact inspection methods often use professional instruments, such as dry eye inspection instruments based on slit lamps or dry eye inspection instruments based on placido discs, to test the patient's eyes or take photos for analysis. For example, the Chinese utility model patent with application number CN201910659617.7, named a dry eye inspection device and method for self-service medical treatment, allows patients to independently complete the detection of multiple indicators of dry eye, including tear meniscus height, lipid layer status, degree of redness of the eyeball, etc. However, this type of professional equipment is often large in size, inconvenient to use, high in cost, and not popular.

[0031] The purpose of the utility model is to provide a clamping type imaging component and dry eye examination equipment in view of the defects of the prior art.

[0032] In some embodiments of the present invention, a clamping imaging assembly is provided, referring to Figures 1 to 5 As shown, it includes a placido plate 7 and a lighting lamp board 10, and also includes: a mounting plate 1, a clamping portion 2 and a fixed protective cover 3;

[0033] The placido disk 7 and the lighting board 10 are both located in the fixed protective cover 3, and the fixed protective cover 3 is arranged on the first mounting surface of the mounting plate 1. The mounting plate 1, the lighting board and the fixed protective cover 3 are all provided with a central through hole corresponding to the camera of the external intelligent terminal. The center of the placido disk 7 is aligned with the central through hole, and the clamping portion 2 is arranged on the second mounting surface of the mounting plate 1. The second mounting surface and the first mounting surface are arranged opposite to each other. The clamping portion 2 is used to make the imaging component fit with the external intelligent terminal so that the camera can shoot the eyes through the central through hole. An anti-wear rubber pad 5 is also provided in the central through hole, and one end of the anti-wear rubber pad 5 is arranged higher than the surface of the first mounting surface after passing through the central through hole, so that when the imaging component is fitted with the external intelligent terminal, the anti-wear rubber pad 5 can contact with the camera to separate the camera from the mounting plate 1.

[0034] The placido plate 7 is arranged on one side of the mounting plate 1, the clamping part 2 is arranged on the other side of the mounting plate 1, and the fixed protective cover 3 is used to shield and protect the placido plate 7, so that the eyes of the person being photographed can be better imaged when viewing the placido plate 7. The clamping part 2 is used to clamp the component on the external intelligent terminal 8 of the external device. When the component and the terminal are attached, the eyes of the person being photographed are close to the central through hole on the fixed protective cover and look at the camera of the intelligent terminal. The camera of the terminal can capture eye images or videos through the central through hole. The external intelligent terminal 8 can store and analyze the captured images and / or videos locally, or the external intelligent terminal 8 can communicate online and upload the captured images and / or videos to the server; in some implementations, the external intelligent terminal 8 can be one or more of a smart phone, a tablet computer, a laptop computer, or a PDA. In this embodiment, a smart phone is preferably used.

[0035] When in use, the placido ring image and / or video captured by the external intelligent terminal 8 is stored and / or uploaded to the server via the external intelligent terminal 8, and the image analysis system of the local or server-side intelligent terminal 8 is used to perform auxiliary diagnosis of dry eyes through image analysis. The component is small in size, easy to carry and use, low in manufacturing cost, and easy to popularize. When using this component, it is more convenient to collect images, not limited by the scene, and patients do not need to go to the hospital, and can take and upload eye images anytime and anywhere. It should be noted that the present utility model does not require the protection of the content of the placido ring image analysis system, so its system composition and specific working method are not described in detail.

[0036] The clamping imaging component has a simple structure. The plasido disk and the clamping part are respectively arranged on the two mounting surfaces of the mounting plate. The layout is compact and reasonable, and it is easy to operate and use. An anti-wear rubber pad higher than the surface of the mounting plate is arranged at the central through hole to make it contact with the camera of the external intelligent terminal and separate the camera from the mounting plate. This can not only effectively protect the camera and avoid wear and damage to the camera when the imaging component and the intelligent terminal are used in conjunction with each other, but the anti-wear rubber pad can also reduce the overhang between the imaging component and the intelligent terminal, making the contact between the imaging component and the intelligent terminal more stable, avoiding problems such as shaking and tilting when cooperating with the external intelligent terminal to shoot the patient's eyes, and is more conducive to shooting eye images.

[0037] The black stripes of the commonly used placido disc are printed with ordinary ink. After the tear film breakup time measurement is completed, the placido cone needs to be removed, and then other test items such as tear meniscus height measurement, lipid layer image acquisition and meibomian gland image acquisition are performed.
