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.

The PT22100 CuraMotion Exer III Plus simulator for arms and shoulders is known in the art for the development of various motor functions of the upper extremities, to strengthen arm muscles, increase the flexibility and mobility of the shoulder girdle (Promedik medical equipment store, RT22100 CuraMotion arm and shoulder trainer Exer III Plus, found January 30, 2017 on the Internet at http://www.pro-medic.ru/index.php?ht=222&detail=9480).

This simulator is a metal case, on the top of which there is a handle that the patient rotates with his hand, making circular movements.

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 inconvenience of working with this device for bedridden patients with impaired hand movements.

Also known from the prior art is the "Snake" simulator, designed to restore arm motor activity, coordination, accuracy and agility of movements (Rehabilitation equipment and REA simulators, "Snake", found on 01/30/2017 on the Internet at http://reaservice.ru / trenazhery-dlya-reabilitacii-i-zdorov-ya / trenazher-dlya-vosstanovleniya-melkoy-motoriki-rak / zmeyka-100h43h20-sm /).

Structurally, this simulator is a “snake” contour made of wire mounted on a wooden stand, on which there are several wooden or metal rings that the patient must move along the wire contour by hand. This simulator has dimensions of 850 × 400 × 450 mm. The wire loop of the simulator can be made in a different shape.

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 rings along the wire loop alternately, then in one, then in the other direction;

b) the impossibility of changing the degree of complexity of the motor exercises offered to the patient;

c) the inconvenience of studying with this device for bedridden patients.

Also known from the prior art is “A simulator - a labyrinth for developing hand motility” (HERCULES Research and Production Association, A labyrinth simulator for developing hand motor skills, was found on 01/30/2017 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 made of steel wire and consisting of straight sections of the same length located relative to each other at 90 degrees angles. A ring is located on the wire structure, which the patient must move along the wire loop, holding it by the handle and tilting and turning the device in different directions to move the ring. This simulator consists of 26 sections of the same length and has dimensions: 415 × 165 × 175 mm, but can be performed in other versions that differ in the shape of the wire loop.

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 impaired hand movement into a certain game activity, which consists in moving the ring along the wire structure made in the form of a maze. Thanks to this, the disturbed process of movement is transferred to another, more secure level of implementation, as well as the inclusion of various psychological components (interest, dedication, etc.) in the process of movement, which contribute to improving the performance of movements and increasing the efficiency of developing disturbed 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;

g) the difficulty of holding the simulator for patients with impaired finger movements

hands.

In order to overcome the shortcomings of the above devices, a tubular simulator device was developed for training in the development of impaired hand movements in patients of a neurological clinic (hereinafter referred to as a tubular simulator).

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

a) providing the patient with a variety of tasks for the development of impaired hand movements, ensuring the maintenance of interest in the classes;

b) 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;

c) providing the ability to hold the simulator in the hand of a patient with impaired finger movements.

The technical result of the claimed utility model is the expansion of the functionality of the "simulator - labyrinth for the development of hand motility", provided by the structural elements of the device, allowing to provide patients of a neurological clinic with a significant amount of various tasks for the development of impaired hand movements with a gradual increase in the complexity of tasks, as well as providing the ability to keep the simulator sick with impaired finger movements.

This technical result is achieved due to the fact that the device contains a longitudinal handle made of plastic with a diameter of 25-35 mm and a length of 100-150 mm, into which a hollow base tube made of transparent plastic is mounted with an external diameter of 15-20 mm and a wall thickness of 3 -4 mm, at the ends of which, through a threaded connection, two adapters made of transparent plastic are fixed, having an L-shaped channel of round shape inside, while to each of the adapters are fixed by a threaded connection There are two hollow tube-links made of transparent plastic with a length of 80-120 mm, the outer diameter and wall thickness of which are equal to the outer diameter and wall thickness of the tube-base, while the rigid connection of the tube-base and tube-links with adapters is carried out by means of plastic locknuts 5-8 mm high, and a chain of adapters and link tubes fixed by locknuts in a similar sequence is repeated 7-12 times, while at the ends of the two extreme link tubes there are fixed There are two plugs made of transparent plastic on the threaded connection, and inside the chain of consecutively connected pipe-link adapters a ball is placed whose diameter is 2-3 mm less than the internal diameter of the pipe-links, and a metal rod with a diameter of 5 is mounted in the central part of the longitudinal handle -6 mm, on which an additional handle is fixed by means of a threaded connection, and straps are fixed on the longitudinal and additional handle, which ensure the fixation of the device in the patient’s hand.

In a preferred embodiment, the length of the base tube is 15-20 mm longer than the length of the handle on each edge.

In a preferred embodiment, the ball may be made of metal or plastic.

The essence of the utility model is illustrated by drawings, which depict:

in FIG. 1 - General view of the "tubular simulator";

in FIG. 2 - view of the "tubular simulator" in the position intended for

holding for an extra perpendicular handle;

in FIG. 3 and 4 - an element for connecting tube links with adapters;

The device (see Fig. 1) consists of a longitudinal handle made of plastic (1) with a diameter of 25-35 mm and a length of 100-150 mm, inside which a hollow base tube (2) made of transparent plastic is mounted, the length of which is 15- 20 mm exceeds the length of the handle (1) on each edge, the external diameter is 15-20 mm, and the wall thickness is 3-4 mm.

The ends of the base tube (2) are made with an external thread intended for fastening two adapters (3) made of transparent plastic and having a round L-shaped channel with two internal threads inside (see Fig. 3). A rigid connection of the adapters (3) with the base tube (2) is carried out by means of counter nuts (4) made of plastic located on the sides of the base tube (2) 5-8 mm high.

To each of the adapters (3) fixed on the base tube (2), two hollow tube-links (5) made of transparent plastic (5), 80-120 mm long, are rigidly connected to the adapters (3) by means of a threaded connection. lock nut (4). The outer diameter and wall thickness of the tube links (5) are equal to the outer diameter and wall thickness of the base tube (2).

Next, the chain of adapters (3) and tube links (5), fixed by means of locknuts (4) in a similar sequence, is repeated 7-12 times.

Thus, the design of the “tubular simulator” consists of chains of 7 to 12 link tubes (5) located on both sides of the base tube (2) in series with each other by means of a threaded connection through adapters (3).

At the ends of the two extreme tube links (5), two plugs made of transparent plastic (6) made of transparent plastic are fixed by means of a threaded joint, the rigid fixing of which is ensured by similar locknuts (4).

Inside the chain of tubes (5) connected in series by adapters (3), a ball (7) is placed, the diameter of which is 2-3 mm less than the inner diameter of the base tube (2) and the tube links (5), due to which it can Easily navigate inside the chain of device elements.

The ball (7) can be made of metal or plastic.

Due to the fact that the tubular simulator consists of tube-links (5) connected by adapters (3) with the possibility of their rotation when the lock nuts (4) are loosened, it is possible to change the external shape of the tubular simulator design by changing the spatial position of its construction elements relative to each other, which allows you to create various options for tasks that provide a variety of movements of the patient’s hand when moving the ball (7) along the structural elements. This plays an important role in maintaining the patient’s interest in classes on the development of impaired arm movements, since a new task is offered to the patient at each lesson.

A variety of tasks is also provided by an additional handle (8), fixed by a threaded connection to a metal rod (9), with a diameter of 5-6 mm, which is mounted in the central part of the longitudinal handle (1).

Thanks to this design, the patient can hold the tubular simulator in two ways: a) by the longitudinal handle (1); b) for the additional handle (8).

If the patient will work with the device using the longitudinal handle (1) (see Fig. 1), then the additional handle (8) fixed to the rod (9) is unscrewed by 20-30 mm from the surface of the longitudinal handle by rotation ( 1), and the patient gets the opportunity to hold the “tubular simulator” with his hand by the longitudinal handle (1), placing a metal rod (9) between the middle and ring fingers of the hand.

If the patient will work with the device using the additional handle (8) (see Fig. 2), then the perpendicular handle (8) is tightly screwed to the longitudinal handle (1) by its rotation, and the patient is able to hold the “tubular simulator” hand for the extra handle (8).

Thus, providing patients with a variety of tasks for the development of impaired hand movements with the possibility of a gradual increase in the degree of difficulty of the tasks is carried out thanks to the following structural elements of the device:

a) easily transformable design, consisting of tube-links (5) movably connected through adapters (3), allowing the specialist to change the shape of the ball (7) and the trajectory of the hand moving the ball (7);

b) the presence of two handles (1 and 8), allowing you to change the trajectory of hand movements that the patient performs in the process of moving the ball (7).

To ensure that the device can be held by patients with impaired finger movements, straps (9) are fixed to the longitudinal and additional handles (1 and 8), which secure the device in the patient’s hand.

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

Before the start of the first lesson, the specialist establishes the structural elements of the device: a) tube-links (5) with adapters (3) and b) handles (1 and 8) in the position that most facilitates the patient moving the ball (7).

The simplest position of the tube-links (5) with adapters (3) is their location in the same plane (see Fig. 1 and 2), since in this case the patient is not required to perform complex movements with his hand, but rather tilt the device in one plane so that the ball (7) moves along the internal cavities of the tube-links (5).

Also, the easiest way to work with the device is to use a longitudinal handle (1) while holding it, which allows you to evenly distribute the weight of the tubular simulator on both sides of the patient’s hand (see Fig. 1).

To change the position of a part of the tube links (5) with adapters (3) relative to each other, the specialist loosens the corresponding locknuts (4), after which sets these tube links (5) with adapters (3) to a new position, rigidly fixing them relative to each other the other by tightening the locknuts (4). The loosening and tightening of the locknuts (4) is carried out manually, since a small effort is enough, however, if necessary, a wrench corresponding to the size of the locknuts (4) can be used.

For use in working with the device of the longitudinal handle (1) (see Fig. 1), the specialist unscrews the additional handle (8) fixed to the shaft (9) 20-30 mm from the surface of the longitudinal handle (1), as a result of which the patient receives the ability to hold the device with your hand by the longitudinal handle (1).

Next, the ball (7) is installed in the initial position near one of the plugs (6), after which the specialist fixes the patient’s hand on the longitudinal handle (1) using a strap (10).

After that, the patient begins to tilt the tubular simulator with his hand, moving the ball (7) inside the device to the opposite plug (3). This sequence of actions, consisting in moving the ball (7) from one plug (3) to another, can be carried out several times during the lesson.

As the patient achieves positive results in the development of impaired arm movements, the specialist complicates the tasks by forming more complex spatial structures from tube-links (5) and adapters (3), requiring the patient to perform more complex hand movements in space by tilting and turning the “tubular simulator. "

The complication of tasks is also due to the use of an additional handle (8) to hold the device by the patient, which provides other trajectories of arm movements (see Fig. 2). To do this, the additional handle (8), by rotating it, is tightly screwed to the longitudinal handle (1), and the patient is able to hold the device with his hand by the additional handle (8).

Before conducting independent classes at home, the patient is first trained to work with the device under the guidance of a specialist, and periodically consults with him during the course of independent classes. In this case, a change in the shape of the design of the tubular simulator is carried out by one of the patient's assistants.

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

Thus, the proposed utility model allows to provide patients with a large volume of various tasks for developing impaired hand movements with a gradual increase in the degree of difficulty of the tasks. In addition, the proposed device provides the ability to conduct long-term courses of independent studies of patients at home.
