Description

This useful model relates to medicine in the section of neurology and neuropsychology and can be used in neurorehabilitation departments of neurological and neurosurgical clinics when conducting classes to restore impaired visual memory in bedridden patients of a neurological clinic.

Along with auditory-speech memory, visual memory is one of the most important types of memory for human life.

Visual memory impairment occurs in patients with a neurological clinic who have organic brain lesions due to various diseases associated with poisoning, infections, injuries, and cerebrovascular diseases.

Of great importance for the effectiveness of the restoration of visual memory is the early start of a course of rehabilitation classes, which should begin immediately after the patient enters the clinic. However, during this period, many patients are bedridden and therefore have difficulty using traditional printed materials intended for memory restoration classes.

Therefore, to restore impaired visual memory in bedridden patients of a neurological clinic, it is advisable to use various devices and simulators.

The electronic game Simon Swipe (Simon Swipe) is known from the existing level of technology. It is a visual memory game simulator (Baby products at wholesale prices, the electronic game "Simon Swipe", found on 06/30/2017 on the Internet at: http: // www.v3toys.ru/index.php?nid=217744).

Structurally, this simulator consists of a plastic case, which has the shape of a torus with a diameter of 230 mm, in the center of which there is one control button, one switch on the rear surface, and touch panels of red, yellow, green and blue are located around the perimeter. The total weight of this device is about 0.6 kg.

During classes with the device, panels of different colors begin to be highlighted in a certain sequence, which must be remembered, and then play this sequence by clicking on the panel of the corresponding color.

The disadvantages of this simulator when using it for classes to restore impaired visual memory in bedridden patients of a neurological clinic are:

a) inconvenience for bedridden patients to deal with this simulator due to its significant size and weight;

b) the complexity of the development and management of this simulator for neurological patients with organic brain lesions due to the limited number of control elements, each of which is multifunctional;

c) providing the patient primarily with negative feedback informing him of improper clicks on the touch panels and thereby focusing the patient on the mistakes made by him;

d) the impossibility of changing the degree of complexity of the tasks offered to the patient when working with this simulator.

Also known from the existing level of technology is the visual memory game simulator “Method Maze” (MenKind, Games, Memory Maze, found June 30, 2017 on the Internet at https://www.menkind.co.uk/memory-maze/#full_description) .

Structurally, this simulator consists of a plastic case, on the edges of which there are four round keys of different colors: red, yellow, green and purple, and in the center of the case there is a switch button. During the lesson, keys of different colors begin to be highlighted for short time intervals in a random sequence, after which the student needs to repeat the sequence of highlighting them by pressing these keys.

The disadvantages of this simulator when using it for classes to restore impaired visual memory in bedridden patients of a neurological clinic are:

a) the inconvenience of working with this simulator of bedridden patients in a neurological clinic due to the difficulty of holding it in the hands, especially in cases of impaired motor functions of one of the hands;

b) providing the patient, first of all, with negative feedback informing him of improper clicks on the touch panels and thereby focusing the patient on the mistakes made by him;

c) the impossibility of adjusting the time interval during which each key is highlighted, the duration of which is too short for patients in a neurological clinic;

d) the impossibility of changing the degree of complexity of the tasks offered to the patient when working with this simulator;

e) a limited set of color keys (4 pcs.) of this device, which narrows the variety of tasks generated by this simulator.

In order to overcome the shortcomings of the above devices, a "Keyboard simulator for exercises to restore impaired visual memory in bedridden patients of a neurological clinic" (hereinafter referred to as "keyboard simulator") was developed.

The tasks to be solved by the claimed technical solution are:

a) ensuring the convenience of retention and comfort of training with the simulator of bedridden patients;

b) providing the possibility of training with the simulator of bedridden patients with impaired motor functions of one of the hands;

c) providing the patient with positive feedback informing him of the correctness of the implementation of each action, and not only of the mistakes made;

d) providing the ability to change the degree of difficulty of the tasks, determined by the number of sequentially highlighted keys and the time during which each key is highlighted;

e) expanding the variety of tasks by increasing the number of color keys.

The technical result of the claimed utility model is to expand the functionality of visual fitness game simulators, which is implemented due to the structural elements of the proposed device, which allows for the restoration of impaired visual memory with bedridden patients in a neurological clinic, as well as with patients who have impaired motor functions of one of the hands, providing their various tasks, with the possibility of changing the degree of their complexity, as well as providing the patient with feedback communication about each action performed by him.

In FIG. 5 is a block diagram of the electrical connection of the elements of the "keyboard simulator".

“Keyboard simulator” (see Fig. 1-4) includes a hollow body made of plastic (1) of regular hexagonal shape, the size between the opposite sides of which is 50-70 mm, height 15-20 mm, wall and bottom thickness 3 -4 mm.

The internal space of the case (1) is divided by plastic partitions (2) into six equally sized trapezoidal side compartments (3a) located along the perimeter of the device case (1), and one central hexagonal compartment (3b) located in the center of the case (1) devices.

The thickness of the partitions (2) is 3-4 mm, and their height is equal to the height of the housing (1) minus the thickness of the bottom of the housing (1).

The dimensions of the side compartments (3a) and the central compartment (3b) are determined locally, based on the total size of the housing (1) of the device and the elements installed in them (see Fig. 3).

A plastic cover (4) is rigidly fixed to the front of the case (1), the size of which is similar to the size of the device case (1), and its thickness is 2-3 mm (see Fig. 4).

In the plastic cover (4), six trapezoidal side cutouts of the same size (5a) are made, separated by bridges 6-8 mm wide, and one central hexagonal cutout (5b), separated by bridges 6-8 mm wide from the side cutouts (5a) .

The location and configuration of the side cutouts (5a) in the plastic cover (4) corresponds to the location and configuration of the side compartments (3a) of the housing (1), and the location and configuration of the central cutout (5b) corresponds to the location and configuration of the central compartment (3b) of the case (1) devices.

The plastic cover (4) is fixed to the device case (1) by means of a screw connection (not shown in the figures) or by any other method, for example, a lock connection.

Inside each side compartment (3a) on the bottom of the housing (1) are rigidly fixed: white LED (10). side disconnect (11a) and several elastic elements (12), on which the lower surfaces of the working keys (6a) are supported.

The operation keys (6a) are made of translucent plastic of different colors (red, yellow, green, purple, brown, blue) and consist of the upper part, the configuration and size of which corresponds to the configuration and size of the side cutout (5a) in the plastic cover (4), and the lower part, made in the form of a collar (not shown in the figures), the configuration and size of which corresponds to the configuration and size of the side compartment (3a) of the housing (1) of the device.

The thickness of the working keys (6a) is determined on the basis of ensuring their structural strength upon repeated pressing and the possibility of free penetration of light from white LEDs (10), which ensure their illumination during classes with the device.

The operation keys (6a) are installed in the side compartments (3a) of the housing (1) with the possibility of reciprocating movement, due to the elastic properties of the material from which the elastic elements (12), for example, rubber, are made.

The upper parts of the side switches (11a) located in the side compartments (3a) of the housing (1) are in contact with the lower surface of the working keys (6a), so that pressing the working key (6a) will activate the side switch (11a) installed underneath.

Inside the central compartment (3b), there are rigidly fixed: yellow LED (7), green LED (8), red LED (9), central disconnector (11b) and several elastic elements (12), on which the lower surface of the control key (6b) rests .

The control key (6b) is made of translucent white plastic and consists of an upper part, the configuration and size of which corresponds to the configuration and size of the central cutout (5a) in the plastic cover (4), and the lower part, made in the form of a shoulder (not shown in the figures ), the configuration and size of which corresponds to the configuration and size of the central compartment (3b) of the housing (1) of the device.

The thickness of the control key (6b) is determined on the basis of ensuring its structural strength when pressed repeatedly and the possibility of free penetration of light from yellow, green and red LEDs (7, 8, 9), providing its illumination during classes with the device.

The on / off switch (13) of the device and a group of 5-10 control buttons (14) are mounted in the side walls of the housing (1).

Inside the housing (1) are fixed: a battery (15) that provides power to the device and a control unit (16) of the device (see Fig. 3).

The battery (15) through the on / off switch (13) of the device is electrically connected (see Fig. 5) to the control unit (16), which is electrically connected to the white LEDs (10) located in each side compartment (3a) and side disconnectors (11a) ), as well as with the yellow, green, red LEDs (7, 8, 9) and the central disconnector (11b) installed in the central compartment (3b).

The battery (15) is electrically connected to a connector (not shown) located on one of the side walls of the housing (1) of the device for connecting the charger.

A strap (17) is fixed to the back of the case (1) of the device, on the bottom side, designed to fix the device on the wrist of a bedridden patient (see Fig. 2).

The fastening of the strap (17) with the device on the wrist of the patient is carried out by means of Velcro tape (18) located at the ends of the strap (17).

The strap (17) may be made of flexible plastic or fabric material.

The "Keyboard simulator for classes to restore impaired visual memory in bedridden patients of a neurological clinic" works as follows:

Before the start of classes, the specialist fixes the “keyboard simulator” using a strap (17) on the wrist of the patient’s left hand or a hand with impaired motor functions.

Further, the specialist, using the on / off switch (13), turns on the power supply to the device, as a result of which the control key (6b) located in the center of the device case (1) starts to be highlighted with a green LED (8), which means that the “keyboard simulator” is ready for operation.

After that, the specialist sets up the device in accordance with the severity of the visual memory impairment of the patient. For this, the specialist, in accordance with the instruction, sets the following parameters by means of the control buttons (14):

a) the number of working keys (6a) sequentially illuminated by white LEDs (10), which is from 3 to 8;

b) the time interval during which each working key (6a) is highlighted, comprising from 1 to 3 seconds, and if necessary more than 3 seconds.

At the initial stage of studies with bedridden patients with a pronounced visual memory impairment, no more than three working keys are highlighted (6a), and their backlighting time is at least three seconds

The patient begins to work directly with the device by pressing the control key (6b), as a result of which the group of working keys (6a) of various colors begin to be highlighted with white LEDs (10) in accordance with the sequence generated by the control unit (16). In this case, the patient must remember this sequence, and then reproduce it by pressing the working keys (6a) according to the sequence of highlighting presented to him earlier.

In the case when the patient presses the operating keys (6a) in the correct sequence, with each press, the control key (6b) is highlighted with a yellow LED (7), due to which the patient receives positive feedback informing him of the correctness of this action.

In the case when the patient makes a mistake, the control key (6b) is highlighted with a red LED (9), which informs the patient about the incorrectly performed action.

In this case, the patient can do the following:

a) to correct the error by correctly pressing the other operating key (6a) corresponding to the highlighting sequence presented to him, as a result of which the control key (6b) is highlighted with a yellow LED (7);

b) repeat the task first by pressing the control key (6b) highlighted by the red LED (9), as a result of which the operating keys (6a) will be highlighted with the white LEDs (10) in the same sequence.

After correctly pressing all the operating keys (6a) in the given sequence, the control key (6b) begins to be highlighted with a green LED (8), giving the patient feedback on the correctness of the entire task and its completion.

To repeat the task, the patient must press the control key (6b) illuminated by the green LED (8), as a result of which the entire cycle of actions described above is repeated.

As the patient achieves positive results in restoring impaired visual memory, the specialist, using the control buttons (14), increases the number of working keys (6a) sequentially illuminated by white LEDs (10) and reduces the time interval during which each working key is illuminated (6a) .

After conducting a lesson to restore impaired visual memory, a specialist can leave the “keyboard simulator” worn on the patient’s arm to enable patients to independently perform exercises to restore impaired visual memory.

Along with the use of the “keyboard simulator” for exercising with bedridden patients, it can also be used for walking patients, who constantly have this device in their hands and can periodically perform visual memory restoration exercises in various conditions: in line for a procedure, for a walk etc.

The importance of the “keyboard simulator” is that its use introduces an element of novelty into the process of studying with patients, turning the process of restoring visual memory into a psychological training that is fascinating and interesting for the patient.

Along with the use of the "keyboard simulator" for classes to restore impaired visual memory in bed patients of a neurological clinic, it can be widely used in the following cases:

a) when conducting classes to restore voluntary attention in patients with a neurological clinic;

b) during the preventive training of visual memory in patients with a neurological clinic;

c) during corrective and developing classes with children with impaired formation of visual memory and attention;

d) during neurocognitive trainings with people of advanced and senile age;

e) as an exciting educational game for healthy children;

e) as a memory simulator, providing the ability to train visual memory in healthy people at any free time.

Thus, the proposed “keyboard simulator” allows classes to restore impaired visual memory with bedridden patients in a neurological clinic, as well as with patients with impaired motor functions of one of the hands, providing them with various tasks, with the possibility of changing the degree of complexity of the tasks offered by patients, as well as providing the patient with feedback about each action performed.

In addition, the proposed device helps to increase the interest of patients in restorative education due to the fact that work is carried out with a simulator that introduces an element of novelty into the process of restoration of visual memory and turns them into an exciting psychological training.

Along with this, the “keyboard simulator” has a wide scope of practical application that goes beyond the boundaries of a neurological clinic, and can be used as a device that contributes to the formation, correction and training of visual memory.
