Description

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

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

Currently, various simulators and devices are used for classes on the development of motor functions of the hands in patients of a neurological clinic.

So, from the existing level of technology, the “CuraMotion Exer III Plus Arm and Shoulder Trainer” is known, which is designed to develop various motor functions of the upper extremities, to strengthen the muscles of the hands, increase flexibility and mobility of the shoulder girdle (Promedik online store. Arm and shoulder simulator PT22100 CuraMotion Exer III Plus, found June 25, 2018 on the Internet at http://www.pro-medic.ru/index.php?ht=222&detail=9480).

Structurally, this simulator is a metal case, in the upper part of which there is a handle that the patient must rotate by hand, making circular movements.

The disadvantages of this simulator when using it during classes to develop motor functions of the hands in patients with a neurological clinic are:

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

b) the uniformity of the movements performed, contributing to the rapid fatigue of patients;

c) the possibility of training with this simulator only if there is a horizontal surface of the table;

d) the inconvenience of practicing with this device for bed patients of a neurological clinic.

Also, from the existing level of technology, the device is known “Block for restoring the functions of the upper limbs”, which is designed to restore the functions of muscles and joints of the hands after injuries, surgery, stroke (Scientific-Production Association "HERCULES", Block for restoring the functions of the upper limbs, found 06/25/2018 on the Internet at http://royal-sport.ru/trenazhery/trenazhery-dlja-invalidov/mehanoterapija-kinezoterapija/blochok-dlja-vosstanovlenija-funk).

Structurally, this device is a steel frame fixed to the wall, on which a pair of blocks is located, through which a rope is threaded, at the ends of which there are handles. During the classes, the patient, holding the rope by the handles, exercises a reciprocating movement up and down, alternately raising one hand and lowering the other.

The disadvantages of this device when used during classes on the development of motor functions of the hands in patients with a neurological clinic are:

a) this device provides a mechanical repetition of the same reciprocating movement of the hands and does not allow you to work on the restoration of any other movements of the hands.

b) the uniformity of the movements performed, contributing to the rapid fatigue of patients;

c) the possibility of training with this device only in specially equipped rooms where it is mounted on the wall;

d) the impossibility of practicing with this device for bed patients of a neurological clinic.

Also, the Catch Ball-1 gaming device is known from the prior art, which is designed to develop coordination of movements, dexterity, and eye measurement (My-Shop.ru online store. The Catch Ball-1 game, found June 25, 2018 d. on the Internet at https://my-shop.ru/shop/products/2208577.html?b45=2_1).

Structurally, this device is a wooden bowl, on the lower surface of the bottom of which there is a handle with a wooden ball tied to it through a lace.

During classes with this device, the student must, by moving the hand holding the device by the handle, toss up the ball tied to the handle, calculating the throwing force so as to catch it in a wooden bowl.

The disadvantages of this device when used during classes on the development of motor functions of the hands in patients with a neurological clinic are:

a) this device is intended for healthy people, and therefore it is practically inaccessible to patients in a neurological clinic with impaired motor functions of the hands;

b) the difficulty of holding the device for patients with impaired finger movements in the hand;

c) this device provides the ability to implement exercises of only one level of difficulty, determined by the size of the wooden bowl and the used wooden ball.

In order to overcome the above drawbacks, a "Funnel simulator for classes on the development of motor functions of the hands in patients of a neurological clinic" (hereinafter referred to as the "funnel simulator") was developed.

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

a) ensuring the availability of classes with a "funnel simulator" to patients of a neurological clinic with impaired motor functions of the hand of varying severity;

b) ensuring the availability of classes with a "funnel simulator", patients with impaired finger movements by fixing the "funnel simulator" on the patient's hand;

c) the possibility of implementing exercises of various degrees of difficulty with the "funnel simulator";

d) ensuring the possibility of training with a "simulator funnel" in various conditions in the absence of a horizontal surface of the desktop;

e) the simplicity of the design of the “funnel simulator”, which contributes to its widespread adoption in the practice of working with patients both in the clinic and when conducting independent classes at home.

The technical result of the claimed utility model is to expand the functionality of the device “Catch the ball-1”, provided by the structural elements of the claimed “simulator-funnel”, allowing classes to develop motor functions of the hands of patients in a neurological clinic due to the possibility of execution with a “simulator-funnel” simple and affordable exercises of varying degrees of difficulty, fixing the “simulator funnel” in the patient’s hand, as well as the possibility of a convenient and easy ball return into the bowl of the "funnel simulator" if it was not caught.

This technical result is achieved due to the fact that the "funnel simulator" contains a structure made of plastic, including the main and additional bowls, which are combined by a holder made in the form of a hollow cylinder with an outer diameter of 22-30 mm and a length of 90-120 mm and both bowls are funnel-shaped with a smooth transition of their narrow parts into the holder, while the inner diameter of the neck of the main bowl is 100-140 mm, and the inner diameter of the neck of the additional bowl is 1.5-2 times less, and the height the new and additional bowls are 50-80 mm each, and round neck 5–10 mm high are made on their necks, while the transition points of the inner walls of the holder and the inner walls of the main and additional bowls are smooth, and through the inner space of the “funnel simulator” "A cord is stretched, on one end of which a ball is fixed, the diameter of which is 20-30 mm less than the inner diameter of the neck of the additional bowl, and the other end of the cord is made in the form of a loop.

In a preferred embodiment of the "funnel simulator", the wall thickness of the holder is 2-5 mm.

In a preferred embodiment of the "funnel simulator", the wall thickness of the main and additional cups is the same and is 2-3 mm.

In a preferred embodiment of the “funnel simulator”, transverse notches are made on the outer surface of the holder.

In a preferred embodiment of the “funnel simulator”, the strap attached to the holder is made of elastic material, for example, rubberized fabric.

In a preferred embodiment of the “funnel simulator”, the ball is made of elastic plastic and is hollow.

In a preferred embodiment of the “funnel simulator”, a braided synthetic rope with a diameter of 2-3 mm, the length of which is 1200-1500 mm, can be used as a lace.

The essence of the utility model "Simulator funnel for classes on the development of motor functions of the hands of patients in a neurological clinic" is illustrated by the drawings, which depict:

In FIG. 1 is a view of a “funnel simulator” without a lace and a ball;

In FIG. 2 is a general view of a “funnel simulator” with a cord and a ball in the position when the main bowl is used;

In FIG. 3 is a general view of a “funnel simulator” with a cord and a ball in the position when an additional bowl is used;

In FIG. 4 is a sectional view of a “funnel simulator”.

The claimed "funnel simulator" (see Fig. 1-3) is a plastic structure made up of a main bowl (1) and an additional bowl (2) united by a holder (3) through which the cord (7) is stretched with a ball fixed on it (8).

 The holder (3) is a hollow cylinder with an outer diameter of 22-30 mm, a length of 90-120 mm, a wall thickness of 2-5 mm (see Fig. 1, 4).

The main bowl (1) is located at one end of the holder (3), and an additional bowl (2) is located at the other end, while both cups (1, 2) are funnel-shaped and their narrow parts smoothly pass into the holder (3).

The inner diameter of the neck of the main bowl (1) is 100-140 mm, and the inner diameter of the neck of the additional bowl (2) is 1.5-2 times less than the inner diameter of the neck of the main bowl (1).

The heights of the main and additional cups (1, 2) are 50-80 mm each, and the wall thickness of the main and additional cups (1, 2) is the same and amounts to 2-3 mm.

On the necks of the main and additional cups (1, 2), round beads (4) are made of rounded shape, 5-10 mm high, which performs the following functions:

a) give additional rigidity to the main and additional bowl (1, 2);

b) provide due to the rounded shape the ease of sliding of the lace (7) along the upper edge of the bowl (1,2) during classes with a “funnel simulator”.

To ensure ease of sliding of the lace (7) in the inner space of the “funnel simulator”, the transition points of the inner walls of the holder (3) and the inner walls of the main and additional bowls (1, 2) are made smooth.

On the outer surface of the holder (3), transverse notches (5) are made to prevent the patient’s hands from slipping during exercises with a “funnel simulator”.

To securely fix the “funnel simulator” in the patient’s hand, the strap (6) is rigidly fixed to the holder (3), made of elastic material, for example, rubberized fabric.

The ball (8) used in the course of training with the "funnel simulator" is made of elastic plastic and is hollow, and its diameter is 20-30 mm less than the inner diameter of the neck of the additional bowl (2).

As a lace (7), a braided synthetic rope with a diameter of 2-3 mm can be used, which can easily glide over a plastic surface, for example, “Twisted polyester rope” (GlobalTex-M Company, Twisted polyester rope, found June 25, 2018 in the Internet at http://2029863.ru/kruchennaya-veryovka).

The length of the lace (7) is 1200-1500 mm, and its attachment to the ball (8) can be carried out in various ways, for example, by gluing.

The other end of the lace (7) is made in the form of a loop (9), which provides the convenience of holding the lace (7) with the patient’s healthy hand during training with the “funnel simulator”.

Work with the "Funnel Simulator for classes on the development of motor functions of the hands in patients with a neurological clinic" is as follows.

Before the start of the training course on the development of the motor functions of the hand, the specialist prepares a "funnel simulator" in such a way as to provide at the initial stage the opportunity for the patient to perform the most simple and affordable exercises.

To do this, the specialist passes the loop (9) with the cord (7) through the holder (3) so that the ball (8) is located in the main bowl (1) of the “funnel trainer”, which is larger than the additional bowl (2 ) (see Fig. 2).

Further, the patient’s hand with impaired movement is fixed by means of a strap (6) on the holder (3), and in the patient’s healthy hand is a loop (9) of lace (7). At the same time, holding the loop (9), the patient’s healthy hand is located near the arm with the “funnel simulator”.

After this, the patient proceeds to perform the exercise, which includes the following movements:

a) toss the ball (8) up to a small height by moving the arm with a "funnel simulator";

b) catch the ball (8) with a “funnel simulator” so that it is in the main bowl (1).

If the ball (8) is in the main bowl (1), then the patient continues to perform this exercise further.

If the ball (8) is outside the main cup (1), the patient returns the ball back to the main cup (1) by pulling the cord (7) held by the healthy hand by the loop (9), after which the exercise continues .

As the patient achieves positive results in the development of motor functions of the hand, complication of exercises performed with the "funnel simulator" is carried out, as follows:

a) by gradually increasing the height of the tossing of the ball (8);

b) by using during the lessons an additional bowl (2) having a smaller neck diameter (see Fig. 3).

Thus, the design features of the "funnel simulator" provide the ability to perform simple and accessible exercises for the patient due to the fact that the ball is thrown directly from the bowl (and not from the position when it hangs on the lace from the bottom), and the patient can gradually increase the height tossing it, thereby complicating the exercise. At the same time, it is possible to conveniently and quickly return the ball (8) to the bowl by pulling the cord (7) with a healthy hand.

The importance of the “funnel simulator” lies in the fact that working with it arouses interest and positive emotions in patients, since the movements performed with the “funnel simulator” are not mechanical, but are playful in nature, which helps maintain interest in the movements performed.

After mastering the use of the "funnel simulator" under the guidance of a specialist, the patient gets the opportunity to conduct independent classes with him both in the clinic and at home.

Along with classes on the development of motor functions of the hands in patients of a neurological clinic, the funnel simulator can also be effectively used in the development of motor functions of the hands that are impaired due to various other diseases, for example, hand injuries, consequences of surgical operations, etc.

In addition to using the "funnel simulator" in clinical practice, it can be widely used in sports and fitness practice, especially when conducting classes with children.

Thus, the “funnel simulator” allows classes to develop motor functions of the hands of patients in a neurological clinic due to the possibility of performing simple and affordable exercises of varying degrees of difficulty, fixing the “funnel simulator” in the patient’s hand, as well as the possibility of a convenient and easy ball return into the bowl in case he was not caught.

Using the “funnel simulator” introduces an element of novelty into the process of rehabilitation classes, turning them into interesting and attractive training for patients.

Due to the simplicity of design and ease of use, the “funnel simulator” can be widely used in clinical practice, allowing patients to carry out exercises to restore the motor functions of the hands both in a hospital and on their own, at home.
