Abstract
A retinoscopy device provided with screen display function comprises a projecting light source (10) projecting light to the eye to be examined, and a receiving mechanism (20) receiving the reflected light from the eye to be examined, wherein the receiving mechanism (20) comprises optical shooting equipment (21) on the reflected light road of the eye to be examined, an image processing device (22)connected with the optical shooting equipment (21) and an image display equipment (23) connected with the image processing device (22). The retinoscopy device provided with screen display function canbe used for the joint observation of all on-site staff, and can precisely decide the axial direction and objectively examine the dioptric system of the eye in the clinical way. In teaching, the utility model is convenient for the teacher to instruct the students promptly, the students and the teacher can observe together all kinds of changing and neutralizing processes of the ametropia eyegroundshadow movement, and the teacher can instruct the students in real time as to the problems occuring during the retinoscopy, which can enable the students to understand the essential points of the retinoscopy straightforward, rapidly and correctly.
Description
Technical field
This utility model relates to medical treatment and teaching aid, particularly the device in the eyes optometry diagnosis.
Background technology
Aspect clinical eyes optometry diagnosis, the doctor can only be with simple eye moving by peephole observation shadow, and the shadow motion video is subjected to another eye finding thing to influence (normalized checking requires eyes to open) easily.If singly open an eye, clinical examination is easy to generate fatigue, examines accuracy thereby influence the shadow in-motion viewing.Can not or be difficult to adapt to be easy to abandon examining the shadow inspection technique with simple eye ophthalmologist who observes or optometrist.
Next, shadow is moving at the bottom of the astigmatism needs the moving direction of definite shadow or axial (0～180 degree), and utilizes traditional inspection shadow inspection technique, the then very difficult moving angle-data of shadow that accurately records.In addition, in tradition inspection shadow was checked, ophthalmologist or optometrist head blocked patient's dead ahead easily and watch sight line attentively than wide-angle, thereby caused refractive diopter than mistake (the tested eye line of incident should be tried one's best and fundus reflex light overlaps).
In teaching, the reflection shadow that the student observes simulated eye by skiascope is moving, thereby learn to check the ametropic method of all kinds, present status of equipment, the student is positioned at the reflection shadow moving (as shown in Figure 1) that unique observation peephole on the simulated eye reflected light path is observed simulated eye by the retinoscopy optometry device, when the student observes, other people can't learn the concrete condition in student's observation process, so, observing the student when utilization inspection shadow simulated eye observation shadow is moving, can not when observation shadow complicated and changeable is moving, accept to demonstrate timely and make a comment or criticism,, finally cause abandoning the training of retinoscopy optometry technical ability so moving understanding produces puzzlement all the time to shadow.
Summary of the invention
This utility model provides a kind of retinoscopy optometry device with screen display function, employing is provided with picture pick-up device at observation peephole place, and with the image feedback of taking to large display screen, accurately hold emotionally condition of tested eye shadow at clinicing aspect for the clinician, and aspect teaching, then watch jointly for all students and instructor, be convenient to the teacher and in time instruct the student, solve inaccurate and inconvenience of clinical observation in the prior art and student and can not in time accept the technical problem of demonstrating and making a comment or criticism in moving observing shadow complicated and changeable.
The retinoscopy optometry device with screen display function that this utility model provides for solving the problems of the technologies described above comprises to the radiative projection source of tested eye, accepts the receiving mechanism of tested eye reflex light; It is characterized in that: described receiving mechanism comprises the optics picture pick-up device that is arranged on the tested eye reflex light path, connect the optics picture pick-up device image processing apparatus and with the image display of this image processing apparatus.
Described optics picture pick-up device is the simulation photographic head; Described optics picture pick-up device comprises CCD or CMOS photographic head; Described image processing apparatus is for including the unitary blood processor of video capture.
Described optics picture pick-up device is a digital camera, and described image processing apparatus is a computer, and described digital camera is crossed USB interface with the computer expert and is connected.
Described image display is a LCDs.
This utility model adopts above-mentioned technical scheme, make this retinoscopy optometry device have image display function, can observe jointly for all personnel on the scene, can utilize computer software at clinicing aspect, put on axial scale with being incident upon optical fundus shadow on the screen around moving, be easy to precisely determine axially, simultaneously, scrutineer's refraction of eye system (face, myopia, hypermetropia and astigmatism) objectively.Aspect teaching, then be convenient to the teacher and in time instruct the student, student and instructor can observe various ametropia optical fundus shadow moving variation and N-process simultaneously, the problem that occurs in instructor's instruction of papil inspection in real time shadow process makes the student understand inspection shadow main points intuitively, rapidly, exactly.

Fig. 2 the utlity model has screen display function retinoscopy optometry schematic representation of apparatus.
The specific embodiment
Describe specific embodiment of the utility model in detail in conjunction with above-mentioned accompanying drawing.
By among Fig. 2 as can be known, this retinoscopy optometry device with screen display function comprises to the radiative projection source 10 of tested eye, accepts the receiving mechanism 20 of tested eye reflex light; It is characterized in that: described receiving mechanism 20 comprises the optics picture pick-up device 21 that is arranged on the tested eye reflex light path, connect optics picture pick-up device 21 image processing apparatus 22 and with the image display 23 of this image processing apparatus 22.Optics picture pick-up device 21 all shoots with video-corder tested eye reflex light situation of change get off, and be reflected on the image display 23 by image processing apparatus 22, can solve the doctor can only be with simple eye moving by peephole observation shadow, and the shadow motion video is subjected to another eye finding thing to influence the problem of (normalized checking requires eyes to open) easily.The teacher can be according to the image change situation, in time instructs the student to observe and understands.
The embodiment of further improvement of the utility model: described optics picture pick-up device 21 is the simulation photographic head, and this optics picture pick-up device 21 can be CCD or CMOS photographic head, and described image processing apparatus 22 is for including the unitary blood processor of video capture.
Further more improved embodiment of the present utility model: described optics picture pick-up device 21 is a digital camera, and described image processing apparatus 22 is a computer, and described digital camera is crossed USB interface with the computer expert and is connected.
Further improved embodiment of the present utility model: described image display 23 is a LCDs.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
