Description

The utility model relates to the field of medicine, specifically to ophthalmology and is intended for the formation of a binocular fusion fusion reflex.

A device for researching fusion (fusion image combiner) is known, which includes racks and a drive (see. Sinoptofor device, Kharkov Instrument-Making Plant, 1979.)

The device allows you to study fusion (image alignment) and fusion reserves in people with binocular vision impairment under artificial haploscopic conditions, presenting two separate pictures in front of the right and left eye at extremely close distances (closer than 5 cm from the eye), i.e. the device allows to determine the quantitative characteristics of binocular vision for near, but does not allow to determine such characteristics for distance.

Known fusion diploscope (see patent for PM No. 23760).

The device includes a support column, a drive, a beam hinged on the rack with guides and measuring strips, three light sources with a rheostat, one of which is mounted on a bracket in the center of the beam, and two others are mounted on movable carriages in the beam guides. At one end of the beam is a bracket for attaching red filters.

This device is designed to determine the area of the working volume of binocular vision for near and far.

Known devices are intended essentially for the study of fusion and fusion reserves in individuals with impaired binocular vision, it does not allow to determine the fusion reflex in the presence of natural objects at long and short distances. In addition, these devices cannot be used for treatment, training of the fusion reflex, strengthening binocular visual acuity, which is very relevant at present.

The prior art has not identified analogues and the closest analogue of the proposed utility model.

The technical task of the utility model is to enable the formation of a natural fusion reflex for long and short distances, to train the fusion reflex and to strengthen binocular visual acuity.

The technical problem is achieved by the fact that a fusion simulator is developed, which includes a pair of stand-alone photo probes and an autonomous power supply charger, each of the photo probes consists of a support stand with a handle holder in the base, an aiming device made in in the form of a visor and a diopter, and a set of point polychromatic photo targets placed in one line with an aiming device, a battery equipped with a switch and a cont Actual assembly for a power charger.

The proposed utility model is illustrated by drawings, in which Fig. 1 shows a general simulator kit, Fig. 2 shows the construction of a photo probe, and Fig. 3 shows a photograph of photo probes with point polychromatic photo targets in the working position.

The fusion simulator includes a right autonomous photo probe 1, a left autonomous photo probe 2 and a power charger 3. Photo probes 1 and 2 have the same design and each of them

represents a support rack 4 with a handle-holder 5 at the base. In the upper part of the support rack 4 is an aiming device 6, consisting of a sight and a diopter. A set of point polychromatic photo targets 7 is located along the support post 4 directly under the sighting device 6 in one line with it. Inside the handle-holder 5 there is a battery (not shown in the drawing) equipped with a switch 8 and a contact node 9 for a power supply charger 3.

The proposed simulator works as follows:

The patient selects an object directly in front of him as a distant target and puts before his eyes the right 1 and left 2 autonomous photo probes. Target 7 photos included. The device is ready to go.

First step. The left eye is closed. The right eye through the sighting device 6 of the right photo probe 1 conduct aiming at a distant target. At the same time, the set of photo targets 7 on the right photo probe 1 are linearly aligned with the distant target. Open the left eye, see two targets of the photo probe - one true, combined with the right photo probe 1 with the distant photo target, and another phantom, which is a set of photo target 7 of the photo probe 1 and located outside the true eye from the left eye target photos, i.e. to the right of the true probe photo target kit 1.

Second step. The right eye is closed. The left eye through the sighting device 6 of the left photo probe 2 conduct aiming at a distant photo target. At the same time, the set of photo target 7 on the left photo probe 2 is linearly aligned with the distant photo target. Open the right eye, see two targets of the photo probe - one true, combined with the left photo probe 2 with the distant photo target, and the other phantom, which is a set of photo target 7 of the photo probe 2 and located outside the true eye from the left eye target photos, i.e. to the left of the true set of probe photo target 2.

The third step is simultaneously the right and left eye through the sights 6 of the right 1 and left 2 photo probes aim with the right and left eye on the distant photo target. With proper aiming, the true image of the photo target of the right 1 and left 2 photo probes are combined with each other in the form of one merged bright photo target, while phantom photo targets are located on the sides of the combined image: the photo target for the right eye is visible on the left from the true photo target, and the phantom photo target of the left eye is visible to the right of the true merged photo target.

Thus, a “trident” figure appears in the field of vision, which characterizes the refusion of fusion (fusion) of the fields of vision of both eyes in natural conditions.

The indicated actions are repeated several times during the time set for each patient during the period of one training session.

The proposed device provides the ability to form a natural fusion reflex for long and short distances.

Training with a “trident” figure allows you to strengthen and develop binocular vision, in most cases binocular vision impairment occurs.

Thus, the proposed utility model provides the possibility of forming a natural fusion reflex for long and short distances, training the fusion reflex and strengthening binocular visual acuity.
