Description

OPTOELECTRONIC EYE DIAGNOSTIC DEVICE

The device relates to the field of medical technology, in particular to devices for an eye examination day and can be used, for example, for an objective assessment and fixing of changes in the state of the fundus.

Analogs of the proposed utility model are devices based on visual observation, photographing and expert evaluation of images of eye elements, in particular the fundus, implemented using a light source, power supply, optical-mechanical system, recording, recording or photographing devices {1,2, 3. Known devices based on the formation using a camera of the image of the eye elements, followed by processing and visualization in a television monitor {4. A disadvantage of the known devices is the instability of the image, due to the fact that any changes in the intensity of illumination, backlighting, subjectivity when focusing inevitably lead to a change in the image and its digital counterpart in the processing device.

The utility model is aimed at increasing the stability of the resulting image of the diagnosed eye elements. The solution to this problem is achieved by the fact that in a known device containing a power supply connected to a light source optically coupled through an optical-mechanical system to the input of the television camera, the output of which is connected to the input of the television monitor, the camera output is also connected to the processing, authentication and storage device, as well as to the input of the background analyzer, the output of which is connected to the regulatory input of the power supply.

The proposed device differs from the known ones in that a background analyzer, a processing, identification and storage device connected to the output of the camera are introduced into the design. This allows you to stabilize the image, making it independent of external illumination, fluctuations in the supply voltage, to conduct an objective quantitative mathematical analysis of pathological changes in the elements of the eye, to identify and store all medical data about the patient in a specially organized database.

The essence of the utility model is illustrated by the drawing, where in FIG. 1 shows a structural diagram of the proposed device. The circuit contains, an adjustable power supply 4, a light source 3, irradiating through an optical-mechanical system 2, an eye 1, the image of which also through it Ё mechanical system 2 enters the camera 6, the output of which is connected to the exits of the television monitor 7, background analyzer 5 and through the input device & It to the processing, identification and storage device 9. The output of the background analyzer 5 is subwoofer to the control input of the power supply 4.

The device operates as follows. A light source 3 powered by an adjustable power supply 4 through an ontomechanical system 2 illuminates the studied elements of the eye, such as the endothelium or fundus, depending on the doctor’s desire and the type of optomechanical system. The luminous flux reflected from the eye 1 passes through the ontic-mechanical system 2 to the input of the camera, on the photosensitive matrix of which an image of the eye element under study is formed. The camera transmits the image to the television monitor 7, as well as through the input device & to the processing, identification and storage device 9. The background analyzer 5, also connected to the output of the camera 6, calculates the average value of the camera signal from the black level and, depending on its value, via the power supply 4 controls the brightness of the light source 3. This makes it possible to stabilize the image, eliminating the influence of instability of the power source and the light source. The processing, identification and storage device 9 performs mathematical image processing, in particular, calculates the area of fundus bleeding, detects tears and detachment of the retina, saves all information about the patient with fixation of the date and time of diagnosis, makes an objective comparison of images of eye elements obtained at different times, assesses the dynamics of change. Using a standard printer allows you to document and formalize diagnostic studies.

The claimed device can significantly improve the accuracy and reliability of diagnostic studies, barely give the course of treatment, and in the presence of the Internet to conduct operational consultations and consultations with specialists from all over the world for each patient individually.
