Description

Technical Field

[0001] The utility model relates to the technical field of synoptophore, in particular to an improved synoptophore. Background Art

[0002] The inspection principle of the synoptophore is to use one objective lens and one eyepiece. The visual fields of both eyes are separated, with the left eye looking at the left picture and the right eye looking at the right picture. The object image is projected onto certain positions of the retinas of both eyes through a convex lens, and then transmitted to the visual cortex through the visual center for analysis. If there is binocular vision, the object images from both eyes can be combined into one object. If there is no binocular vision, the strabismus degree of the patient can be confirmed by adjusting with the scale on the synoptophore panel, and other relevant data can be analyzed. The synoptophore can be used to examine the three-level visual functions of patients with strabismus and amblyopia, measure the subjective and objective strabismus angles of strabismus patients, etc., to understand the degree of amblyopia of the patient, whether there is abnormal retinal correspondence, determine the treatment plan for strabismus and amblyopia patients, and judge the curative effect.

[0003] The synoptophore inspection includes subjective strabismus angle measurement, objective strabismus angle measurement, eye position inspection, binocular visual function inspection, and special inspection. The binocular visual function inspection includes simultaneous vision, fusion vision, and stereopsis. The synoptophore treatment training includes disinhibition training, fusion training, correction of fixation nature, and abnormal retinal correspondence correction training.

[0004] During the inspection or treatment training process using a traditional synoptophore, the replacement of pictures is an essential key step. Currently, the picture cassette of the synoptophore can generally only hold one picture. After inspection or treatment training, different pictures need to be replaced for inspection tests and training. And currently, there are many types of pictures, which are not convenient for placement and storage. In case of negligence, damage, or loss, the present device provides an improved synoptophore for the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide an improved synoptophore for the deficiencies of the prior art to solve the above-mentioned technical problems.

[0006] The embodiment of the utility model adopts the following technical solution: including a synoptophore, a picture storage and replacement device is provided on the synoptophore to provide inspection and training for patients by replacing the picture content in a rotating manner. There are several test pictures with different patterns inside the picture storage and replacement device. There are two picture storage and replacement devices, and the two picture storage and replacement devices are symmetrically arranged. Each of the two picture storage and replacement devices includes a limiting mechanism and a picture storage mechanism. The limiting mechanism is arranged on the synoptophore, and the picture storage mechanism is rotatably connected to the limiting mechanism. The limiting mechanism can limit the picture storage mechanism.

[0007] Further, the limiting mechanism includes a limiting plate, a limiting block, a spring piece and a clamping block. An observation notch is provided on the limiting plate. The limiting plate is arranged on the synoptophore and replaces the position required for the traditional picture box on the synoptophore. The observation notch on the limiting plate corresponds to the path of the traditional high-power objective lens on the synoptophore. The clamping block is arranged at the upper end of the limiting plate. The spring piece is arranged at the side end of the limiting block. The clamping block is connected to the spring piece and is arranged towards the picture storage mechanism.

[0008] Further, the picture storage mechanism includes a rotating disk and picture storage frames. The rotating disk is rotatably connected to the limiting plate. A plurality of limiting grooves are provided on the rotating disk. A plurality of picture storage frames are provided. The plurality of picture storage frames are equidistantly arranged around the inside of the rotating disk. Square grooves are provided at positions corresponding to the plurality of picture storage frames on the rotating disk. The plurality of square grooves and the corresponding picture storage frames are in a matching state. The number of the plurality of limiting grooves is the same as that of the plurality of picture storage frames and they are arranged in a one-to-one correspondence. The head end of the clamping block can be placed in the uppermost limiting groove among the plurality of limiting grooves. A clamping groove for limiting the placement of the picture is provided in each of the plurality of picture storage frames.

[0009] Further, the picture storage frame that is horizontally arranged and corresponds to the observation notch among the plurality of picture storage frames is the position of the picture to be inspected.

[0010] Further, an indication mark is provided at the upper end of each of the plurality of picture storage frames.

[0011] Further, a cover body that covers the rotating disk by magnetic attraction is rotatably connected to the rotating disk.

[0012] The above at least one technical solution adopted in the embodiment of the present utility model can achieve the following beneficial effects:

[0013] In the present utility model, by improving the original picture box on the synoptophore, a plurality of picture patterns to be tested are evenly distributed around a picture storage and replacement device in a circular manner. When replacing different picture patterns, only a certain angle needs to be rotated to realize the replacement and inspection operation of different pictures, which greatly solves the problem that it is more troublesome to frequently replace pictures. At the same time, it is also convenient for storing the required pictures to avoid damage and loss of the pictures.

[0014] When the required examiner needs to replace different picture contents during the eye examination or training process, the rotating disk can be rotated. The rotation of the rotating disk drives the rotation of different pictures in several picture storage frames. After the rotating disk is rotated, the clamping block will be disengaged from the corresponding limiting groove by the acting force. When the rotating disk is rotated by a certain angle and the clamping block is inserted into the next corresponding limiting groove, it indicates that the replacement of the picture pattern is completed. The whole picture operation process is relatively convenient. Moreover, during the binocular visual function examination or training process of the examiner, the rotating disk can be rotated to switch the pictures to achieve different visual effects;

[0015] When placing the required inspection pictures into the picture storage frame, first open the cover of the rotating disk, and place the upper ends of the pictures corresponding to the arrow directions of the indication signs in sequence. Then the required inspection pictures can be placed. After the pictures are located inside the corresponding picture storage frames, the required inspection pictures will be limited by the card slots to prevent them from falling out. After the pictures are placed, close the cover, which can prevent dust from entering the inside of the rotating disk. BRIEF DESCRIPTION OF THE DRAWINGS

The limit mechanism 21 is arranged on the synoptophore 1, and the picture storage mechanism 22 is rotatably connected to the limit mechanism 21. The limit mechanism 21 can limit the picture storage mechanism 22.

[0028] By improving the original picture box on the synoptophore 1, this device evenly distributes multiple picture patterns to be tested around a picture storage and replacement device 2. When replacing different picture patterns, only a certain angle needs to be rotated to achieve the replacement inspection operation of different pictures, greatly solving the problem that it is rather troublesome to frequently replace pictures. At the same time, it is also convenient to store the required pictures to avoid damage and loss of pictures.

[0029] In a further preferred embodiment of the present utility model, the limiting mechanism 21 includes a limiting plate 211, a limiting block 212, a spring piece 213 and a clamping block 214.

When the rotating disk 221 is rotated by a certain angle and the clamping block 214 is clamped into the next corresponding limiting groove 223, it means that the replacement of the picture pattern is completed. The whole picture operation process is relatively convenient. And during the binocular vision function examination or training process of the examiner, the rotating disk 221 can be rotated to switch the pictures to achieve different visual effects.

[0032] In a further preferred embodiment of the present utility model, the picture storage frame 222 that is horizontally arranged and corresponds to the observation notch 215 among a number of the picture storage frames 222 is the position of the picture to be examined required;

[0033] When the examiner observes through the eyepiece by fitting the eye with the lens barrel, after being refracted by the mirror, the required picture to be examined in the corresponding picture storage frame 222 is observed through the objective lens and through the observation notch 215.
