Description
Technical Field
The utility model relates to the technical field of optical medical appliances, in particular to a portable meibomian gland detection device.
Background
Meibomian glands are specially differentiated sebaceous glands which are located in the meibomian of the eyelid, are vertically arranged and open at the lid margin, and the discharged lipid secretions are uniformly coated on the surface of the tear film through the transient eye movement of the eyelid to form the outermost layer of the tear film, which has an important effect on maintaining the health of the ocular surface: can effectively delay evaporation of the aqueous layer of the tear film, reduce the surface tension of the tear film, enhance the stability of the tear film, prevent the skin at the eyelid margin from being immersed by the tear water, provide a smooth and flat optical interface to reduce injury caused by transient eyes, and act as a barrier to prevent the tear film from being polluted by sebaceous gland secretion. Meibomian gland dysfunction (Meibomian Gland Dysfunction, MGD) is a chronic, diffuse meibomian gland abnormality, a clinically common ocular surface disorder. MGD causes insufficient secretion of meibum, causes excessive evaporation of tear film and reduced stability, and can cause eye discomfort such as redness, itching, irritation, burning, dryness, vision fluctuation or lacrimation, which is a major factor in evaporative dry eye. MGD is typically accompanied by one or more signs of reduced gland numbers, loss of gland ends, displacement of gland openings, or blockage of gland openings. At present, the meibomian glands are usually imaged and photographed by adopting infrared rays, and the symptoms are observed from the pictures to prevent or treat the eye diseases; however, many blood vessels and other visible light interference can be seen on the current pictures of the meibomian glands, and the meibomian glands cannot be clearly distinguished, thus increasing the difficulty in judging the symptoms. In addition, the prior art detection systems or devices are bulky, very cumbersome to move, and have significantly reduced operability and flexibility when examining patients.
Eyelid illumination systems and methods for imaging meibomian glands for meibomian gland analysis as proposed in the prior art in the patent document publication CN 105792729B. In one embodiment, the patient's eyelid is IR transilluminated with Infrared (IR) light. Transillumination images of the patient's eyelid are captured, with meibomian glands shown in dark outline areas and non-glandular material shown in bright areas. This provides a high contrast image of the meibomian glands resembling X-rays. The lid transillumination images of the meibomian glands can be analyzed to determine and diagnose the meibomian glands in the patient's eyelid. The eyelid may be transilluminated by an eyelid flipping device configured to grip and flip the eyelid for imaging an inner surface of the eyelid. Additionally, IR surface meibomian photographic images of the meibomian glands can also be captured and combined with the transillumination images of the meibomian glands to provide higher contrast images of the meibomian glands.
The meibomian gland imaging system comprises a multiplying power mirror assembly, wherein an infrared camera is arranged at the rear end of the multiplying power mirror assembly, an annular infrared emission device is arranged at the front end of the multiplying power mirror assembly, and an infrared filter is arranged at the front end of the multiplying power mirror assembly or between the multiplying power mirror assembly and the infrared camera. After the above mode and structure are adopted, when the pictures of the meibomian glands are shot, the blood vessels on the meibomian glands can be filtered, the meibomian glands can be clearly displayed, and a doctor can conveniently observe and diagnose.
A portable near-infrared meibomian gland imaging system as proposed in the prior art in the patent document with publication number CN 214180383U. The utility model uses polarized extinction technology and narrow-band filtering technology to deduct the reflection interference of background light and illumination light, thus realizing clear imaging of meibomian glands, and uses the existing image acquisition and analysis software to analyze and calculate the physical parameters such as meibomian gland morphology, structure and missing area. In this utility model, the first linear polarizer and the second linear polarizer are orthogonally arranged.
As shown above, the current detecting system or device for meibomian glands may be interfered by other visible light, dust, etc., so that the imaging effect is poor, and thus the diagnostic result is affected, or the imaging range is limited due to the fact that the device is relatively heavy and inflexible, and the diagnostic result is further affected. While the above problems are solved in the technical solution of the prior art CN214180383U, the polarization structure of the device is easily polluted and damaged, the polarization structure of the device is used as a main structure for making incident light uniform and filtering reflected light, if the polarization structure is damaged, the functions and effects of the whole device are affected, and the integrated design is also unfavorable for subsequent repair and replacement.
Furthermore, there are differences in one aspect due to understanding to those skilled in the art; on the other hand, as the inventors studied numerous documents and patents while the present utility model was made, the text is not limited to details and contents of all that are listed, but it is by no means the present utility model does not have these prior art features, the present utility model has all the prior art features, and the applicant remains in the background art to which the rights of the related prior art are added.
