Description

The utility model relates to medicine, to the section of neurology and neuropsychology and can be used in the departments of neurorehabilitation of neurological and neurosurgical clinics when conducting classes to restore visual memory in patients with a neurological clinic.

Visual memory is one of the types of memory that provides fixation and reproduction of visual images. Along with auditory-speech memory, visual memory is one of the most important types of memory for human life.

Visual memory impairment occurs with damage to the occipital regions of the cerebral cortex due to various neurological diseases.

Various methods are used to restore visual memory, among which one of the most common is the method for storing several images, followed by finding image data among a group of other, similar images.

Books on training visual memory mainly describe the methods of training to restore it. Moreover, we have not identified special simulators for the restoration of visual memory in patients with a neurological clinic.

There is a known method in which students are invited to remember five abstract images, and then find the image data in a table containing 25 images similar to those remembered (Angel Navarro Memory does not change. Tasks and puzzles for the development of intelligence and memory, - M .: Mann, Ivanov and Ferber, 2015, p. 84).

The disadvantage of this method, as well as other similar methods, from the point of view of using them in the practice of rehabilitation training, is that they are not intended to restore impaired visual memory in patients of a neurological clinic, but to train it in healthy people. As a result, these methods are often complex and may not always be used in practical work with patients.

At the same time, as a rule, a limited number of techniques are given in various sources of information, and they are not designed for long courses. These courses are not able to provide long classes to restore impaired visual memory, the need for the duration of which is estimated in months or more.

The task to which the claimed technical solution is directed is to ensure the possibility of carrying out, with the necessary level of complexity and variety, long-term courses for the restoration of impaired visual memory in patients with a neurological clinic.

The technical result provided by the device we developed is the possibility of its simple use - turning the optically impermeable glass into transparent with the touch of a button on the control panel, which allows you to adjust the level of complexity, variety and time of presentation of images during classes to restore visual memory, as well as time courses to restore impaired visual memory.

The technical result is achieved by the fact that a simulator was created for training to restore visual memory in patients of a neurological clinic, while it contains a base to which a plastic frame is pivotally attached, divided into cells by internal plastic partitions, in each of which electrochromic glass is mounted, and electrochromic glass each cell through an electric wire is connected to a control panel that can connect via an adapter to the mains, the lower part of the plastic frame equipped with magnetic locks, and in the center of the lower part there is a rigid protrusion for raising and lowering the frame.

The essence of the device "Training simulator for the restoration of visual memory in patients with a neurological clinic" is illustrated by drawings 1-10.

In FIG. 1 is a general view of the device in a state where all cells of the plastic frame are opaque;

In FIG. 2 is a general view of the device during training, when an image is presented to the patient through a transparent cell for storing;

In FIG. 4-10 - examples of sheets of paper with various tasks intended for use in the device during classes to restore visual memory.

The simulator for the restoration of visual memory in patients with a neurological clinic (see Fig. 1-3) contains a plastic or metal base (1), to which a plastic frame (3), separated by internal partitions (4), is attached via a swivel joint (2) on cells (5), in each of which an electrochromic glass (Smart Glass, smart glass) is inserted, which changes its transparency under the influence of electric current. The electrochromic glass of each cell (5) is connected via an electric wire (10) to the control panel (11), and the control panel (11) is connected via the adapter (13) to the mains supply.

A protrusion (9) is located on the lower part of the plastic frame (3), which enables it to be raised and lowered when sheets of paper (6) with images (7) are inserted into the device. In addition, the lower part of the plastic frame (3) is equipped with magnetic locks (8).

The device is powered through an adapter (13) connected to the mains via a cable (12).

The device operates as follows.

For classes using the device, sheets of paper (6) are used, containing various images (7) of objects, objects, symbols, geometric shapes, the number of which corresponds to the number of cells (5) on the plastic frame (3) of the device. Moreover, each image (7) is presented twice, on the left and right side of the sheet of paper (6), where there are two groups of identical images, but with a different arrangement of images relative to each other. Each sheet of paper (6) can contain from 4 to 12 pairs of different images (7) (see Fig. 4-10).

Before the start of classes, the specialist lifts a plastic frame (3) by the ledge (9) and arranges on the basis of (1) the device several sheets of paper selected for work with the patient (6) with images (7), and then fixes them in the device using magnetic locks (8) of a plastic frame (3). As a result of this, each image (7) on a sheet of paper (6) appears under one of the cells (5) of the plastic frame (3).

Further, the specialist warns the patient that he will be presented with a certain image for memorization, while the specialist sets, using the control panel (11), for a certain time (1 to 10 seconds) to be transparent electrochromic glass of the cells necessary for occupation (5) with in them images (7) and located on the left or right side of the frame (3). As a result, the images (7) located under the cells (5) become visible to the patient.

After that, a specialist using the control panel (11) disables the transparency of the glass of these cells (5), as a result of which the images (7) below them are no longer visible.

The main feature of the electrochromic glass used in the device (Smart Glass, smart glass) is its ability to turn from transparent glass into optically impermeable with the touch of a button on the control panel connected to this glass.

The principle of operation of electrochromic glass is based on electronically controlled scattering of the light flux. It consists of liquid crystal particles located between two layers of a special electrically conductive film. In the off state, the crystals are arranged randomly, forming an opaque matte white surface. When voltage is applied, the crystals instantly assume a parallel position with respect to the electric field, and the glass becomes transparent.

An important feature of this type of electrochromic glass for its use in medical equipment designed to work with patients in a neurological clinic is:

- 4th generation Polyvision ™ film, powered by safe low-voltage power;

- the structure of electrochromic glass, which is a tempered safety triplex (if this glass breaks during operation, then its fragments do not scatter in different directions, but remain on the inner film);

Further, the specialist immediately (or after some time) through the control panel (11) makes transparent all cells (5) located in another part (relative to the image presented before) of the plastic frame (3). In this case, the patient must find among this group of images, those images that were presented to him for memorization. In case of difficulties, the specialist can help the patient by again making memorable images visible for a short time, and a group of images located in another part of the sheet of paper invisible.

After the patient independently or with the help of a specialist finds the presented images, the specialist makes the cells (5) of the plastic frame (3) opaque using the remote control (11) and warns the patient that new images will be presented to him for memorization, repeating thus the whole cycle of action. Moreover, each time there is an alternation of the presented images, which consists in the fact that the image is presented once, for example, from the left side of the sheet of paper, the next time from the right side, etc.

In the course of work with one sheet of paper (6) containing images (7), as many cycles of actions can be performed as different images it contains, that is, from 4 to 12. After that, the specialist lifts a plastic frame (3) by the protrusion (9) and removes from the device a used sheet of paper (6) with images (7), and classes continue with another sheet of paper (6) with images (7).

During classes with the device, the degree of complexity of the tasks offered to the patient is determined:

- the time of presentation to the patient of an image intended for memorization;

- the time interval between the presentation of the image and the presentation of a group of images located on another part of a sheet of paper;

- the degree of external similarity of images located on this sheet of paper;

- the number of images simultaneously presented to the patient for memorization.

Along with classes to restore visual memory in patients with a neurological clinic, this device can be used for the following purposes:

1. when working on the restoration of visual-spatial memory in patients with a neurological clinic;

2. when working on the restoration of image representations in patients of a neurological clinic with acoustic-mnestic and amnestic aphasia;

3. when working on restoration of attention in patients of a neurological clinic;

4. during correctional developmental classes with children who have any deviations in the development of mental functions, in particular memory, attention, visual and spatial perception;

5. during neurocognitive training with the elderly;

6. As an educational game designed for healthy children.

Along with the above capabilities of this device, it can also be used as a compact bench-top tachistoscope that allows you to present individual images or groups of images for limited time intervals, lasting less than one second. Due to this, this device can be used for the following purposes:

1. during the neuropsychological examination, during which the process of visual perception is studied under conditions of limiting presentation time;

2. during conducting classes in rehabilitation education, during which work is carried out on the restoration of the dynamic parameters of mental activity.

Thus, the “Simulator for the restoration of visual memory in patients of a neurological clinic” has a wide scope of practical application that goes beyond the boundaries of a neurological clinic and can be used as a device that promotes the development, formation, correction, restoration, and training of visual memory. At the same time, this device is easy to use, providing adjustment of the level of complexity, variety and time of presentation of images during classes to restore visual memory due to the presence of a frame with cells and electrochromic glass and a control panel.
