Problems solved by technology

[0004] The generalizability and availability of this system is limited due to its expensive, bulky and non-ergonomic features
[0005] Moreover, the mobile device is only used as an image capture device, functionally limiting its usefulness, especially with regard to the achievable field of view extension and consequent inspection accuracy
[0006] In addition, it is very difficult for non-technical personnel to use the system
In particular, the bracket of the mobile device may deviate from the position of the instrument, thus requiring frequent adjustment of the position

Abstract

The invention provides an eye ground camera device based on mobile equipment. The device comprises the mobile equipment and an optical component which are detachably connected. The optical component comprises an optical accessory, an illumination component and a coupling apparatus, wherein the optical accessory includes one partially-reflected surface; the illumination component is located at one end in an outer frame and is connected to an inner wall of the outer frame; a light direction of the illumination component faces towards the optical accessory and is vertical to a shooting direction of a camera of the mobile equipment; light of the illumination component is irradiated to the reflected surface and forms a reflected light beam pointing to eyes in a visual field of the camera; the coupling apparatus and the mobile equipment are detachably connected; and the coupling apparatus positions the optical accessory to a position corresponding to the camera of the mobile equipment. By using the eye ground camera device based on the mobile equipment, a common medical person and even a ordinary person who has one intelligent mobile phone can shoot without mydriasis and mydriatic eye ground; and a useful tool is provided for a wide range of eye ground screening and eye ground disease monitoring.

Description

technical field [0001] The invention relates to the field of optical equipment, in particular to a fundus imaging device based on mobile equipment. Background technique [0002] In the field of medical treatment and health, fundus photos or video data are an important basis and indicator for evaluating eye health and disease severity. Currently, this examination is performed in ophthalmology clinics using non-portable funduscopic instruments on bulky and expensive stands aided by optical and computer equipment. However, such instruments have proven to be impractical and greatly limit fundus examinations, especially for bedridden, pediatric, disabled patients, or anyone else unable to attend an ophthalmology clinic in person. [0003] The relevant systems are available at www.welchallyn.com / promoticms / iExaminer / index.html. [0004] Due to its expensive, bulky and non-ergonomic features, the system's generalizability and availability are limited. [0005] Furthermore, the m...
