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 on the development of impaired arm movements in patients of a neurological clinic.

Violation of hand movements occurs in patients with a neurological clinic due to various organic lesions of the brain and peripheral nervous system associated with vascular diseases, injuries, infections, etc.

For the development of impaired hand movements in patients of a neurological clinic, various devices and simulators are used.

Thus, from the prior art, the Kinetec Maestra hand and wrist CPM simulator for passive joint development is known, which is intended for the development of the wrist joint, hands and fingers (MEDBUY. Medical equipment Rehabilitation. Kinetec Maestra hand and wrist CPM, found 07.02.17 at Internet at the address http://medbuy.ru/trenazher-mnogofunkcionalnyj/trenazher-dlya-passivnoj-razrabotki-sustavov-kinetec-maestra-hand-and-wrist-cpm).

Structurally, this device is a base on which the patient’s hand is located, and the hand is fixed on the movable part of the device, which carries out forced uniform movements of the hand with an electric drive.

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

a) the monotony and uniformity of work with this device, which consists in moving the wrist in one direction or the other;

b) the inconvenience of exercising with this device for bedridden patients.

The Rotational Exercise Machine (RATAY Rehabilitation, The Rotational Exercise Machine (pronation-supination) is also found on the Internet at http://ratay.kz/reabilitatsionnoe-oboradovanie7/trenazhery-dlya-hod-by-razvitiya- melkoj-motoriki / trenazher-rotatsionny-j-pronatsiya-supinatsiya-art-404-1-ya-mogu).

This simulator is designed to train the pronation-supination of the forearm and hand. Structurally, it consists of a base, on one end of which there is a stand for the forearm, and on the other - a rotary handle with adjustable resistance to rotation. During classes, the patient makes rotational movements of the hand, contributing to the development of movements of the wrist and forearm.

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

a) mechanical repetition of the same stereotypical circular motion of the hand in one plane without the possibility of working on the restoration of any other movements of the hand;

b) the inability to assess the angle at which the simulator handle is rotated during the patient’s training with the device;

c) the difficulty of working with this device for bedridden patients, since during training the patient’s forearm should be in a fixed position on the simulator stand located on the table surface.

Also known from the prior art is “The labyrinth simulator for the development of hand motility” (HERCULES Research and Production Association, the labyrinth simulator for the development of hand motility, was found on 02/07/2017 on the Internet at http://royal-sport.ru/trenazhery/ trenazhery-dlja-invalidov / razvitie-koordinacii / trenazher-labirint-dlja-razrabotki-motorik #).

This simulator is designed to develop motor skills and develop hand coordination during rehabilitation after a stroke. Structurally, it is a wire structure rigidly fixed on the handle with a constant contour shape on which the ring is located, which the patient must move along the wire structure, holding it by the handle and tilting and turning the device in different directions to move the ring.

Unlike the devices discussed above, the labyrinth simulator provides the ability to develop impaired motor skills of the patient’s hands, not through mechanical repetition of the same type of movements, but by incorporating the disturbed hand movement into a certain game activity, which helps to increase the efficiency of the development of impaired hand movements.

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

a) the ability to move the ring only along the same contour of the wire structure, which causes the patient to quickly get used to, leading to a decrease in interest in occupation;

b) the impossibility of increasing the degree of complexity of the tasks performed by the patient as they achieve positive results in the development of arm movements;

c) the ability to hold the simulator in the hand in only one way - by the handle on which the wire structure is rigidly fixed;

d) the difficulty of keeping the simulator in patients with impaired finger movements.

In order to overcome the shortcomings of the above simulators, the device “Ring simulator for training in the development of impaired hand movements in patients of a neurological clinic” was developed (hereinafter “ring simulator”).

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

a) providing the patient with a variety of exercises to develop various parts of the arm.

b) maintaining interest in the classes due to the variety of exercises used;

c) a change in the degree of complexity of the tasks performed by the patient as they achieve positive results in the development of impaired arm movements;

d) providing the patient with feedback on the results of the movements performed during classes with the device;

d) providing the ability to hold the device in the patient’s hand with impaired finger movements.

The technical result of the claimed utility model is the expansion of the arsenal of technical means intended for the development of impaired arm movements in patients of a neurological clinic, provided by the structural elements of the device, allowing patients with various exercises of varying difficulty to develop various parts of the arm with a feedback function about the movements performed , as well as the ability to keep the device sick with impaired finger movements.

This technical result is achieved due to the fact that the device contains a sliding handle on the end of which a tubular holder is rigidly fixed in the hole of which a rubber gasket is installed and a transparent ring with a diameter of 200-300 mm, made of a transparent plastic tube, is fixed to rotate, the fixation of which is provided by a tubular screw clamp holder, while inside the transparent ring a metal ball is placed with the possibility of movement, and on the outer surface the surface of the transparent ring with the same angular intervals marked and arranged to move two rubber rings, while the handle of the device is made with the possibility of sliding and consists of a hollow outer tube and 2-3 inner tubes of corresponding diameters, telescopically connected to each other and fixed by means of clamps -clips, and 1-2 straps are attached to the outer tube.

In a preferred embodiment of the device, the transparent plastic tube of which the transparent ring is made has an outer diameter of 20-30 mm and a wall thickness of 2-3 mm.

In a preferred embodiment of the device, the diameter of the metal ball is 1-2 mm less than the inner diameter of the transparent tube from which the transparent ring is made.

In a preferred embodiment of the device, the marks on the surface of the transparent ring are dark-colored lines 2-4 mm thick.

In a preferred embodiment of the device, the hollow outer tube included in the handle design has a length of 120-150 mm and a diameter of 25-35 mm.

In a preferred embodiment, the device of the tube of which the handle consists can be made of plastic or metal.

In a preferred embodiment, the clamps located on the outer and inner tubes can be of a collet or eccentric type.

The essence of the utility model "Ring simulator for classes on the development of impaired hand movements in patients with a neurological clinic" is illustrated by the drawings, which depict:

In FIG. 1 - general view of the "ring simulator";

In FIG. 2 - view of the "ring simulator" in the position when the handle is installed inside the ring;

In FIG. 3 - handle "ring simulator";

In FIG. 4 is a view of a “ring simulator” with the handle extended.

The device (see Fig. 1-3) consists of a sliding handle (1) at the end of which a tubular holder (2) is rigidly fixed in the hole of which a rubber gasket (12) is located and a transparent ring (3) with a diameter of 200-300 is mounted rotatably mm

The transparent ring (2) is fixed in the tubular holder (2) in different positions relative to the handle (1) by means of a screw clamp (4) located on the tubular holder (2).

The transparent ring (3) is made of a transparent plastic tube with an external diameter of 20-30 mm and a wall thickness of 2-3 mm.

A metal ball (5) is placed inside the transparent ring (3), the diameter of which is 1-2 mm smaller than the inner diameter of the transparent tube from which the transparent ring (3) is made, which ensures its easy movement along the inner cavity of the transparent ring (3) at various inclinations and turns of the "ring simulator".

At the same time, on the outer surface of the transparent ring (3) with equal angular intervals of 10 or 15 degrees, marks (6) are applied in the form of lines made of dark color 2-4 mm thick, designed to provide the specialist and patient with feedback that allows monitoring the angle of rotation of the patient's transparent ring (3) during the execution of an exercise with a "ring simulator".

So, for example, in the case when the handle (1) is located inside the transparent ring (3) (see Fig. 2), the patient makes “swinging” movements with the “ring simulator”, receiving information about the angles of rotation of the arm with the device according to the marks (6) that reaches the metal ball (5) during the rotation of the device in one direction or another.

The presence of these marks (5) allows you to use the device when diagnosing the severity of violations of hand movements. In this case, the specialist, knowing the angular intervals between the marks (6), gets the opportunity to determine the exact data on the possibilities of movement of the sore arm.

Along with marks (5), two rubber rings (7) located with the possibility of movement on the surface of the transparent ring (3) are important for providing the patient with feedback. By moving the rubber rings (7) along the surface of the transparent ring (3), the specialist sets the boundaries that the metal ball (5) must reach during the patient’s movement with the device.

The transparent ring (3) can be rotated in a tubular holder (2) relative to the handle (1) to any angle within 360 degrees, followed by rigid fixation with a screw clamp (4), due to which it is possible to form different types of exercises characterized by different trajectories of arm movements with device.

The main options for the positions of the handle (1) of the device relative to the transparent ring (3) are:

a) the location of the handle (1) outside the transparent ring (3), but in the same plane with it (see Fig. 1);

b) the location of the handle (1) inside the transparent ring (3) (see Fig. 2);

c) the location of the handle (1) perpendicular to the transparent ring (3);

d) the location of the handle (1) at different angles to the transparent ring (3).

Along with the different position of the handle (1), the device is forming

exercises with different trajectories of hand movements is possible due to various ways of holding the device by the handle (1) by the patient.

So, for example, when the handle (1) is located inside the transparent ring (3) (see Fig. 2), the "ring simulator" can be held in the following ways:

a) when the device is held in the patient’s extended arm, and due to the “rocking” movements of the hand, the ball (5) moves left and right along the inner cavity of the transparent ring (1);

b) when the device is held in the patient’s hand, which is lowered down or raised up, when the ball (5) moves around the inner cavity of the transparent ring (1) due to “circular” movements of the hand.

An additional formation of exercises with different trajectories of hand movements is possible due to a change in the length of the handle (1) of the device (see Fig. 4), which is made with the possibility of sliding and consists of a hollow outer tube (8) 120-150 mm long, 25- diameter 35 mm, and 2-3 internal tubes (9) of the corresponding diameter, which are telescopically connected to each other and are fixed by means of clamps-clamps (10).

The outer tube (8) and inner tubes (9) can be made of plastic or metal, and the clamps-clamps (10) located on them can be collet or eccentric type

Thus, due to the structural elements of the device, various exercises are formed that allow you to include the developed arm in movements of varying degrees of difficulty, as well as maintain the interest of patients in the classes, as the patient performs not the same movements with the device, but diverse and different exercises .

To ensure that the device can be held by patients with impaired finger movements, 1-2 straps (11) are attached to the outer tube (8) of the handle (1).

Work with the "Ring simulator for classes on the development of impaired hand movements in patients of a neurological clinic" is as follows:

Before conducting a course on the development of impaired arm movements, a diagnosis is made of the severity of impaired arm movements of the patient.

Before starting the diagnosis, the specialist fixes the patient’s hand on the handle (1) of the device using the strap (11), after which the patient is asked to perform a number of diagnostic tasks characterizing the severity of motor impairment of the hand.

To this end, the specialist loosens the screw clamp (4), then sets the transparent ring (3) so that it is located around the handle (1) of the device (see Fig. 2), after which it fixes the position of the transparent ring (2) by tightening the screw clamp (4). After this, the patient’s forearm is located on some support (table, bedside table), and the specialist instructs the patient to slowly turn the brush with the device several times in one or the other direction, while fixing to which marks (6) of the transparent ring (3) it reaches ball (5).

The results obtained are entered into the examination protocol and are used further during classes on the development of impaired movements.

Similarly, the specialist measures violations of the patient’s hand movements at other positions of the handle (1) relative to the transparent ring (7):

a) when the handle (1) is located outside the transparent ring (7), but in the same plane with it;

b) when the handle (1) is perpendicular to the plane of the transparent ring (7).

Based on the results of the studies, the specialist selects exercises and develops an appropriate program of rehabilitation classes.

Before the start of the lesson on the development of impaired hand movements, the specialist moves the rubber rings (7) located on the transparent ring (3) to a position that is 5-10 degrees more than the rotation angles of the device obtained during the examination.

Next, the specialist fixes the patient’s hand on the handle (1) using the strap (11), after which the patient is offered various exercises that differ in the position of the handle (1) relative to the transparent ring (3) and the method of fixing the patient’s hand on the handle (1) of the device .

So, if the patient holds the device by the handle (1) located in the same plane with the transparent ring (3) (see Fig. 1), he can perform the following movements with him:

a) when the transparent ring (3) is located perpendicular to the horizontal surface, the patient makes “swinging” movements with the device with his hand, trying to make the ball (5) move left and right along the inner cavity of the transparent ring (1) to reach the rubber rings (7 ) installed by a specialist in certain places of the transparent ring (3);

b) when the transparent ring (3) is located in a plane parallel to the horizontal surface, the patient makes “circular” movements with the device using his hand, moving the ball (5) throughout the entire internal cavity of the transparent ring (1).

As patients achieve positive results in the development of impaired hand movements, the specialist complicates the tasks by:

a) the movement of rubber rings (7) mounted on a transparent ring (3) over large angular distances, requiring the patient to increase the rotation of the arm with the device in different directions;

b) a gradual increase in the length of the handle (1), by loosening the clamps-clamps (10) and sliding the inner tubes (9), followed by their fixation by means of clamps-clamps (10).

Before conducting independent classes at home, the patient is previously trained to work with the device under the guidance of a specialist, and periodically consults with him during the course of independent classes.

Along with classes on the development of impaired motor skills in patients of a neurological clinic, this device can also be used in the development of motor skills of the hands, impaired due to various other diseases, for example, injuries, consequences of surgical operations, etc.

Thus, the proposed utility model "Ring simulator for classes on the development of impaired hand movements in patients of a neurological clinic" allows patients to be provided with various exercises of varying degrees of difficulty to develop different parts of the arm with a feedback function about the movements performed, as well as the ability to hold the device for patients with impaired finger movements. In addition, the proposed device allows you to diagnose violations of hand movements, and thus provides the ability to conduct long courses of independent classes of patients at home.
