Description

This useful model relates to medicine in the section of neurology and neuropsychology and can be used in the departments of neurorehabilitation of neurological and neurosurgical clinics during classes to restore the motor functions of the hands in patients of a neurological clinic with impaired motor sphere.

Impairment of motor functions of the hands can be observed in patients of a neurological clinic with various organic brain lesions associated with poisoning, infections, injuries, and vascular diseases of the brain.

Research in neurology shows that due to neuroplasticity, compensation and the ability to restore impaired motor functions of the limbs by performing repetitive and task-oriented various movements are provided.

A promising new area of motor rehabilitation is the use of virtual reality technologies, when using a computer simulation of three-dimensional space, a patient can see on the monitor screen the movement of various arms and legs performing various movements (V.I. Skvortsova, Shock attack on stroke, Science and Life, 2007, No. 8, found on 10.17.2016 on the Internet at: http://www.nkj.ru/archive/articles/11373/).

Various devices and simulators are used to develop and restore impaired arm movements in patients using virtual reality.

A rehabilitation simulator for functional therapy of the upper extremities is known from the prior art (Production and sale of medical equipment. ArmeoPower (MedKontakt), found on 10/17/2016 on the Internet at: http://medkontakt.spb.ru/catalog/massage/detenzorterapiya/1048 /).

The ArmeoPower rehabilitation simulator has dimensions of 150 × 80 × 80 cm and is intended for stroke patients with brain injury and other neurological diseases, as a result of which motor functions of the hands have worsened. The ArmeoPower simulator is a robotic exoskeleton with a height-adjustable electric lifting column that provides arm support and allows the training of motor skills of the upper extremities in the virtual space of a computer monitor with direct feedback on the movements performed by the patient.

The disadvantages of this simulator when using it to develop impaired hand movements in patients with a neurological clinic are:

a) the bulkiness and significant dimensions of this simulator, which complicate its use during independent studies of patients at home;

b) the ability to use only the software that comes bundled with this simulator and includes a limited number of computer games;

c) the presence of this simulator mainly in large or well-funded clinics due to its high cost.

The ArmeoSpring rehabilitation simulator is also known in the art for the restoration of motor functions of the upper extremities in patients with strokes, injuries of the brain and spinal cord, and other neurological pathologies of the upper limbs (Production and sale of medical equipment. MedContact, ArmeoSpring, found 10.17.2016 in the Internet at http://medkontakt.spb.ru/catalog/reabilitation/vosstanovlenie-funktsiy-verkhnikh-konechnostey/1047/).

The rehabilitation ArmeoSpring exercise machine represents an ergonomic orthosis which fastens on a hand and allows to support its weight. The patient’s work is carried out in the virtual space of a computer monitor by using appropriate computer games that provide the patient with direct feedback regarding his movements.

The disadvantages of this simulator when using it to develop impaired hand movements in patients with a neurological clinic are similar to the disadvantages of the simulator discussed above.

Despite the significant complexity of the above devices, their operation is based on a principle similar to the principle of working with virtual reality, which is implemented using a standard computer mouse.

A standard computer mouse is a mechanical manipulator that converts a hand movement into a control signal that can be used to move the cursor on the screen of a computer monitor.

The principle of operation of a computer mouse is that it perceives its movement in the working plane (usually on the surface of the table) and transfers this information to the computer. A program running on a computer, in response to a mouse movement, produces an action on the screen that corresponds to the direction and distance of this movement.

A computer mouse includes an optical displacement sensor, one or more control buttons, as well as additional control details, one of which is a scroll wheel.

The optical sensor consists of a double optocoupler - an LED and two photodiodes (usually infrared) and a disk with holes or luciform slots, blocking the light flux as it rotates. When you move the mouse, the disk rotates, and a signal is taken from the photodiodes at a frequency corresponding to the speed of movement of the computer mouse. The phase difference between the two photodiodes determines the direction of rotation. (Wikipedia. Free encyclopedia, Computer mouse, found on 10.17.2016 on the Internet at http://ru-wiki.ru/wiki/Mouse_computer).

One of the standard computer mice known from the prior art is the DIALOG MOP-00BU mouse, (Dialog company. Multimedia and computer accessories, Pointer MOP-00BU USB optical mouse, found on the Internet at https://www.dialoginvest.com/ ? lang = 5 & mode = catalog & model = 100364).

Structurally, this mouse consists of an oval-shaped plastic case measuring 95 × 55 × 30 mm, on the top of which there are two control buttons with a scroll wheel, and an optical sensor located on the bottom of the case. Connecting the device through the USB port of the computer.

The disadvantages of this and similar computer mice when used to develop impaired hand movements in patients with a neurological clinic are:

a) the process of moving a computer mouse is carried out exclusively in the horizontal plane and does not allow the development of movements in the vertical plane,

b) with prolonged use of a computer mouse, carpal tunnel syndrome occurs, manifested by prolonged pain and numbness of the fingers of the hand.

Carpal tunnel syndrome (carpal tunnel syndrome) affects mainly people who work a lot at the computer. The main cause of this disease is the compression of the median nerve at the place of its passage through the carpal tunnel (tunnel). Carpal tunnel syndrome combines various inflammations within the joint, its swelling, and damage to tendons and muscles. The first symptoms of carpal tunnel syndrome are numbness, tingling, and burning of the fingers (paresthesia). At first, they do not last long and pass, but after some time a person begins to feel these unpleasant symptoms constantly. Due to the decrease in the speed of the impulse along the branches of the median nerve, the movements become weak and inaccurate, their coordination is disturbed (AyZdorov.ru, carpal tunnel syndrome. Causes and symptoms of carpal tunnel syndrome, found on the Internet at http: //www.ayzdorov. com / lechenie_sindrom_zapyasnogo_kanala_chto.php).

One way to prevent the occurrence of carpal tunnel syndrome is to use a vertical computer mouse, so-called by its method of holding in the hand. Working with it allows you to maintain the natural position of the joint, in which the normal blood supply to the tissues is not disturbed, and the muscles responsible for the rotation of the hand (arch support and pronators) are not subjected to excessive tension or stretching.

Unlike the keys of a standard computer mouse, in a vertical mouse, the left button turns into the upper control button, and the right button into the lower one. Between them is usually a scroll wheel. In addition, there is a place under the thumb for the user to get a “fulcrum”, thereby providing maximum comfort to the hand (Poisk-podbor.ru Computer mice. Give battle to the tunnel syndrome. Rescue gadgets: mouse-like, found on the Internet via the address http://computer-mouse.ru/article/articles/daesh-boj-tunnel-nomu-sindromu-spasitel-nye-gadzhety-myshepodobnye/19.html).

The closest to the claimed technical solution is a vertical computer mouse WOWPEN (ErgoTools.ru, Ergonomic devices. Vertical computer mouse WOWPEN, found on the Internet 10/17/2016 at http://ergotools.ru/vertical_mouse/wireless_vertimouse/wowpen_wireless_ black.html) .

Structurally, this computer mouse consists of a plastic cone-shaped case 72 × 102 × 85 mm in size, on the side of which there are two control buttons with a scroll wheel, and on the opposite side of the case there is a recess for the thumb. On the bottom of the device, which is rigidly connected to the device’s body, there is an optical sensor and plastic pads that facilitate sliding the mouse on a horizontal surface. Connecting the device through the USB port of the computer

Thanks to this form of the case, the vertical mouse has improved ergonomic properties, namely, when working with it, the hand maintains its natural position, preventing the appearance of carpal tunnel syndrome.

The disadvantages of a vertical computer mouse when used to develop impaired hand movements in patients with a neurological clinic are:

a) the computer mouse is designed exclusively for work in the horizontal plane and cannot be used to develop hand movements in the vertical plane;

b) in patients with impaired movements of the fingers of the hand, problems may arise in holding the device in the hand;

c) the difficulty of ensuring stable contact of the optical sensor with the working surface on which the mouse is moving, for patients with impaired arm movement.

This is due to the fact that a patient with impaired hand movements cannot always hold a vertical mouse so that its bottom touches the working surface. Therefore, as a result of tilting even at a small angle of the vertical computer mouse in one direction or another, the bottom of the mouse with the optical sensor will detach from the working surface, as a result of which the operation of the vertical mouse will be disrupted.

In order to overcome the above disadvantages, a simulator device was developed - a vertical computer mouse for training to restore the motor functions of the hands in patients of a neurological clinic (hereinafter referred to as the simulator).

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

a) providing the possibility of developing motor functions of the hands not only in the horizontal, but also in the vertical plane;

b) the compactness of the simulator, providing the possibility of its use during independent training of patients at home;

c) ensuring the stability of the simulator in case of accidental tilt of the patient relative to the working surface at a small angle;

d) providing the ability to hold the simulator in the hand by patients with impaired finger movements;

e) the availability of the device for medical institutions with a low level of funding, as well as for individuals to conduct independent studies;

f) the ability to use any software designed to work with a conventional computer mouse.

The technical result of the claimed utility model is to expand the functionality of a vertical computer mouse due to the design features of the proposed "simulator", allowing it to be used in the practice of restoring the motor functions of the hands by including them in various movements in horizontal and vertical planes with stable operation of the device in the case of a slight inclination relative to the working surface, as well as providing the possibility of conducting classes with patients with neurological oh clinic with impaired movement of the fingers.

This technical result is achieved due to the fact that the device contains a cone-shaped plastic case with two control buttons with a scroll wheel located on it, as well as a bottom with an optical sensor connected to the case, and a square or rectangular niche with dimensions of 20-30 × is made in the center of the bottom 30-40 mm and a depth of 15-20 mm, inside of which through elastic elements such as springs or rubber inserts a plastic platform is movably mounted, in the center of which an optical sensor is mounted, while at the bottom Two magnetic plates are mounted on the bottom, and plastic pads are rigidly fixed around the bottom perimeter, and on the side of the case where the control buttons with the scroll wheel are located, a fixing strap made of rubberized fabric is rigidly fixed.

In a preferred embodiment, the height of the plastic housing is 80-120 mm, and the bottom connected to it has a width of 70-90 mm and a length of 100-120 mm.

In a preferred embodiment of the device, a recess for the thumb is located on the side of the housing opposite to the control buttons and the scroll wheel.

In a preferred embodiment, the outer surface of the plastic platform is made of plastic with a low coefficient of friction.

In a preferred embodiment, devices mounted on the bottom of the lining body are made of plastic with a low coefficient of friction, have a round or oval shape, and their total number is 4-6 pieces.

In a preferred embodiment of the device, a switch is located on the bottom of the bottom, which locks the control buttons and the scroll wheel.

In a preferred embodiment of the device, an optical sensor with control buttons and a scroll wheel is connected by an electric cable to a USB hub connected to a USB port of the computer.

The essence of the utility model "Simulator - a vertical computer mouse for classes on the restoration of motor functions of the hands of patients in a neurological clinic" is illustrated by the drawings, which depict:

in FIG. 1 - general view of the simulator;

in FIG. 2 - general view of the simulator, bottom view;

in FIG. 3 - diagram of connecting the simulator to a computer via a USB hub.

The simulator (see Figs. 1 and 2) consists of a conical shape made of plastic housing (1) with a truncated apex, oval base and a height of 80-120 mm, which is rigidly connected by a screw connection (13) to a plastic bottom (2) 70-90 mm wide and 100-120 mm long, in the center of which a square or rectangular niche (3) is made with dimensions of 20-30 × 30-40 mm and a depth of 15-20 mm.

Inside the niche (3) through elastic elements (4) (such as springs, rubber inserts, etc.) a plastic platform (5) is movably mounted, in the center of which an optical sensor (6) is mounted, similar to the optical sensor of a standard computer mouse. The outer surface of the plastic platform (5) is made of plastic with a low coefficient of friction such as fluoroplastic, which makes it easy for the platform (5) to slide along the working surface.

Structurally, the simulator is designed so that in the idle position the platform (5) extends beyond the bottom surface of the base (2) of the device by 5-8 mm, and in the working position, when the simulator is installed on the horizontal surface of the table, the elastic elements (4) are compressed due to the weight of the simulator, and the platform (5) with an optical sensor (6) is firmly pressed against the horizontal surface of the table.

Two magnetic plates (8) are mounted in the lower part of the bottom of the simulator (2), which makes it possible to hold the device on a vertical surface made of magnetic material, in particular on the surface of the training magnetic board, which is used when working with this device.

Also, around the perimeter of the bottom (2) of the Trainer, 4-6 overlays (9) are rigidly fixed, made of plastic with a low coefficient of friction, for example, fluoroplastic, which makes it easy to slide the device on the working surface.

The pads (9) have a round or oval shape and protrude 1-2 mm beyond the bottom surface of the bottom (2) of the exercise machine.

The elastic elements (4) provide the possibility of constant contact of the optical sensor (6) mounted in the platform (5) with the working surface along which the simulator is moving. If the patient makes any awkward movement with the hand holding the simulator, as a result of which the device tilts by 10-15 degrees, the platform (5) with the optical sensor installed on it (6) will remain in contact with the working surface, along which The simulator is moving.

Two control buttons (10) and a scroll wheel (11) are located on one of the sides of the simulator case (1), which, together with the optical sensor (6) located on the bottom of the device (2), are connected via a cable (7) to a USB hub ( 14) connected to the computer’s USB port.

On the side of the case (1) of the simulator, opposite the control buttons (10) and the scroll wheel (11), there is a recess (15) for the thumb, which provides the convenience of holding the device in the hand.

For reliable fixation of the “Trainer” in the patient’s hand with impaired finger movements of the wrist, having difficulty holding the device in the hand, on the side of the case (1), where the control buttons (10) and scroll wheel (11) are located, is rigidly fixed made of rubberized fabric fixing strap (16).

On the bottom of the bottom (2) of the "Simulator" there is a switch (12), which locks the control buttons (10) and the scroll wheel (11) if the lesson is carried out with a patient with impaired fingers of one of the hands.

In this case, the functions of the buttons (10) and the scroll wheel (11) are controlled by using a standard computer mouse (17) (see Fig. 3) with functioning buttons and a scroll wheel and a non-functioning optical sensor.

A standard computer mouse (17) is installed in front of the patient on the table next to his healthy hand and is connected via cable to a USB hub (14) connected to the computer’s USB port. At the same time, in order for the optical sensor to not function, it is enough to apply an opaque material, such as a patch.

Along with the above-described wire-type simulator, a wireless-type simulator can also be used.

The simulator can be made with the location of the control buttons (10) and the scroll wheel (11) both on the right and on the left side of the body (1), which makes it possible to work with the device for patients with impaired movements of both the right and left hands.

Work with the simulator - a vertical computer mouse for classes on the restoration of motor functions of the hands in patients with a neurological clinic is as follows.

At the initial stage of classes, the hand movements are restored in the horizontal plane by moving the simulator along the horizontal surface of the desktop, which ensures mastery of the patient device and getting used to working with it, somewhat later the movement of the hand with the simulator in the vertical plane is included in the training process.

Before starting classes, a specialist connects the simulator via a cable (7) to a USB hub (14) connected to a computer’s USB port. Further, the specialist changes the program settings of the computer mouse in order to increase the space of movement of the simulator along the working surface used during the lessons.

For this purpose, the specialist opens the “Control Panel” on the computer monitor on the computer monitor (the description is given for the Windows XP operating systems), enters the Mouse section, then in the Index Settings submenu, increases to the necessary level “ The speed of the pointer. " The value of the set parameter is determined based on the amount of movement available to the patient’s arm.

Further, by means of a fixing strap (16), the simulator is fixed on the patient’s hand.

Next, the specialist launches on the computer some pre-selected computer-friendly game that is easy to control, which makes it possible to include the patient’s hands working with the Trainer in certain actions.

In particular, at the initial stage of exercises to restore hand movements, a computer game can be used, for example, that is driving a car that travels along a wide road without encountering significant obstacles, and the patient controls his movement by moving the simulator along the working surface to the left or right.

Gradually, the specialist begins to use more complex computer games in working with the patient, work with which provides a complication of the movement process, which includes movements not only in one direction, but along the entire plane of the working space.

Such a game, for example, can be, for example, shooting at various targets, during which the patient needs to shoot at targets located in different parts of the computer monitor.

After mastering a patient’s work with the device in a horizontal plane, the process of restoring hand movements in a vertical plane is included in the training process.

For this purpose, a vertical training board with a magnetic base is installed next to the patient, which facilitates the patient's retention of the simulator on its vertical surface due to the magnetic plates mounted in the bottom (2) of the device (8), which facilitate holding the device.

As a board with a magnetic base, for example, a magnetic floor board ДП-11 (к) can be used (Avocado, Children's furniture, Rotary combined magnetic floor board, found on the Internet on 10/17/2016 at http: //wvvw.avokado-shop .ru / shop / shop_podrobnee.php? num_cat = 14 & num_in_cat = 49 & g_cid = 631).

The use of horizontal and vertical surfaces for exercises to restore the motor functions of the hands can alternate. So, for example, on one day a lesson is held using the horizontal surface of the desktop, on another day - a lesson using the vertical surface of the magnetic board.

Along with restoring the process of hand movements in patients of a neurological clinic, the proposed "Trainer" can also be used to restore hand movements that are impaired due to various injuries and diseases of the musculoskeletal system.

An important feature of the proposed "Simulator" is that, unlike many large and expensive simulators for restoring hand movements, the proposed device can be widely used to restore the motor functions of the hands at home.

In addition, the simulator can also be used to train thin and precise hand movements in a vertical plane for people whose professional activities are related to the motor sphere, for example, athletes.

Thus, the “simulator-vertical computer mouse for classes on restoring the motor functions of the hands in patients of a neurological clinic” can be widely used in the practice of neurorehabilitation not only in clinical but also at home, which will significantly increase the efficiency of the process of restoring impaired hand movements.
