Abstract

The invention provides a portable support and imaging system for acquiring fundus images, and solves the problems that an optical and lighting system of an existing fundus camera is more complicated,larger in size, and not suitable for mobile operation. The portable support comprises a supporting plate, an optical lens and a telescopic adjustment assembly; the two ends of one side of the supporting plate are provided with clamping ports, and the other side of the supporting plate is connected with the optical lens through the telescopic adjustment assembly; the supporting plate is provided with a light transmission hole used for a camera light path of a smart phone to pass through and a lighting hole used for a flash lamp light path to pass through, and the light transmission hole is aligned with the optical lens; the telescopic adjustment assembly is used for adjusting the distance between the optical lens and the supporting plate; the imaging system comprises the smart phone and theportable support, and the smart phone is clamped in the clamping ports of the supporting plate.

Description

technical field [0001] The invention relates to a medical auxiliary inspection instrument, in particular to a portable bracket and an imaging system for acquiring fundus images. Background technique [0002] The eye is the visual organ for human beings to perceive the world. The external scene forms an inverted real image on the retina through the eye optical system. The retina is equivalent to the receiver in the optical imaging system and is very important for obtaining external information. Therefore, the retina, as the only tissue in the whole body that can observe blood vessels and their distribution under living and non-invasive conditions, has become an important window for the diagnosis of eye diseases and related systemic diseases. Retinal capillary lesions can be used for early diagnosis of hypertension, diabetes, thrombosis and other diseases. Therefore, fundus imaging examination has also become a popular object of clinical medicine and modern scientific research...
