Description

Ladle simulator for classes on the development of motor functions of the hands in patients with a neurological clinic

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 the motor functions of the upper limbs, to strengthen the muscles of the hands, increase flexibility and mobility of the shoulder girdle (Promedik Online Store. Trainer for arms and shoulders PT22100 CuraMotion Exer III Plus, found on July 20, 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 07/20/2018 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 lessons, the patient holding the rope by the handles, performs a reciprocating movement up and down with his hands, alternately raising one arm 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, and does not allow you to work on restoring any other hand movements;

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 intended for the development of coordination of movements, dexterity, and eye measurement (My-Shop.ru online store. The Catch Ball-1 game, found July 20, 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.

In the course of training with this device, the person who is engaged needs to throw the ball attached to the handle by moving the hand holding the device by the handle, calculating the throwing force so that it is caught 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 lack of the ability to change the degree of complexity of the exercises performed with this device;

c) since most patients did not have the skill to work with this device in their previous experience, this activity is unusual for them and causes additional difficulties.

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

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

a) the use as a basis for a simulator of a household item that is familiar to many patients, in particular a kitchen ladle, the actions of which are strengthened by the past experience of many patients, therefore are more secure and accessible for implementation, while the shape of the bucket (tank formed by the bottom and wall) possesses properties that provide the ability to implement simple and accessible for patients exercises of varying degrees of complexity;

b) ensuring the availability of classes with a “training ladle” to a patient in a neurological clinic with impaired motor functions of the arm of varying severity;

c) the possibility of implementing exercises of varying degrees of difficulty with the “bucket simulator”;

d) providing the possibility of convenient and quick return of the ball to the capacity of the "simulator-bucket" in case it was not caught by the patient;

e) providing the possibility of training with a "simulator-bucket" in various conditions in the absence of a horizontal surface of the desktop;

e) the simplicity of the design of the “simulator-bucket”, which contributes to its widespread introduction into the practice of working with patients, both in the clinic and in independent studies 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-bucket”, allowing classes to develop motor functions of the hands of patients in a neurological clinic, due to the possibility of performing exercises accessible to patients varying degrees of complexity, as well as the possibility of convenient and quick return of the ball to the capacity of the "simulator-bucket".

In FIG. 3 is a side view of a “ladle simulator” without a lace and a ball;

In FIG. 4 is a sectional view of the capacity of a “training bucket”.

The claimed "simulator-bucket" (see Fig. 1-3) is a container (1) made of plastic, to which a handle (2) is secured with a screw connection and can be rotated, and a through hole is made in the bottom of the container (1) (4) through which the cord (9) is stretched with the ball (10) fixed on it.

Capacity (1) has a cylindrical shape and consists of a bottom and a wall, between which a smooth transition is made from the outside, providing ease of sliding of the lace (9) during training with a “ladle simulator”.

The inner diameter of the bottom of the tank (1) is 100-150 mm, and its thickness is 2-3 mm.

The height of the wall of the tank (1) is 50-90 mm, and the thickness is 2-3 mm.

In the center of the lower part of the bottom of the tank (1), a thickening (3) of a circular shape with a diameter of 40-50 mm and a height of 6-8 mm was made, in the center of which a through hole (4) with a diameter of 15-20 mm was made (see Fig. 2, four).

At the same time, the edges of the through hole (4) on the upper and lower sides of the thickening (3) are made of a rounded shape, which ensures ease of slipping of the lace (9) during training with a “ladle simulator”.

On the upper edge of the container (1), a rounded edging (5) is made with a radius of 3-5 mm which performs the following functions:

a) gives additional rigidity to the wall of the tank (1);

b) due to the rounded shape provides ease of sliding of the lace (9) along the upper edge of the container (1) during classes with a “training ladle”.

In the upper part of the container (1), a shank (6) (see Fig. 4) is made of a thickness of 8-12 mm, a length of 35-45 mm, in which a mounting hole is made with a diameter of 6-10 mm for mounting the rotary handle (2).

The handle (2) is made of plastic, its length is 130-160 mm, and its cross section is rectangular with rounded edges with a width of 25-30 mm and a height of 15-20 mm.

At one end of the handle (2), a rectangular groove and mounting holes are provided for fastening the handle (2) to the shank (6).

The width of the rectangular groove in the handle (2) corresponds to the thickness of the shank (6), and its depth exceeds the length of the shank (6) by 10-20 mm.

The diameter of the mounting holes in the handle (2) corresponds to the diameter of the mounting holes in the shank (6).

 The handle (2) is attached to the shank (6) by means of a screw connection, which includes a wing screw (7) with a nut.

To ensure rigid fixation of the handle (2) in various positions relative to the container (1), notches 0.3-0.6 mm deep are made on both sides of the shank (6), as well as on the inner surfaces of the groove in the handle (2).

In the lower part of the handle (2), an elastic strap (8) made of rubberized fabric is fixed with a width of 15-20 mm, which ensures the fixation of the patient's arm during training with a "ladle simulator".

The ball (10) used in the course of training with the “bucket simulator” is made of elastic plastic and is hollow, and its diameter is 30-60 mm.

As a lace (9), a braided synthetic rope with a diameter of 2-3 mm can be used, which has the property of easy sliding on a plastic surface, for example, “Twisted polyester rope” (GlobalTex-M Company, Twisted polyester rope, found on July 20, 2018 in the Internet at http://2029863.ru/kruchennaya-veryovka).

The length of the lace (9) is 1200-1500 mm, and its fastening to the ball (10) can be carried out, for example, by means of an adhesive joint.

The other end of the lace (9) is made in the form of a loop (11), which provides the convenience of holding the lace (9) with the patient’s healthy hand.

To prevent accidental slipping of the loop (11) through the hole (4) in the bottom of the container (1) during training with a “ladle simulator”, a stopper (12) is installed in front of the loop (11) on the cord (9), which is a plastic washer thick 3-5 mm, the inner diameter of which is equal to the diameter of the lace (9), and the outer diameter exceeds the diameter of the hole (4) in the bottom by 1.5-2 times.

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

To perform the simplest exercises with the “ladle simulator”, at the beginning of the course, the handle (2) is set to the initial (horizontal) position. For this purpose, the thumb screw (7) is loosened, the handle (2) is moved to its initial position, and then fixed with the thumb screw (7).

Then, using the strap (8), the handle (2) is fixed in the patient’s hand with impaired movement.

At the same time, a loop (11) of a cord (9) is located in a healthy hand of a patient, and a healthy hand of a patient holding a loop (11) is located near a hand with a “training bucket”.

Before performing the exercise, the ball (10) is located inside the container (1) of the “ladle simulator”.

The exercise performed by the patient with a “ladle simulator” includes the following movements:

a) toss the ball (10) up to a small height, by moving the arm with a “training bucket”;

b) catch the ball (10) with a “ladle simulator” so that it is inside its container (1).

In the event that after performing the above steps the ball (10) is inside the tank (1) of the “ladle simulator”, then the patient continues to carry out the exercise further.

If the ball (10) is outside the capacity (1) of the “simulator-bucket”, then the patient returns the ball (10) to the capacity of the container (1) by pulling the cord (9) with a healthy hand over the loop (11), after which the exercise continues.

As the patient achieves positive results in the development of motor functions of the arm, complication of exercises performed with a "ladle simulator" is carried out by:

a) a gradual increase in the height of the tossing of the ball (10);

b) changing the position of the handle (2) relative to the container (1) in order to change the trajectory of movements made by the patient’s hand holding the “simulator-bucket”.

To do this, the wing screw (7) is loosened and the angle of rotation of the handle (2) relative to the container (1) is changed. The maximum angle of rotation of the handle (2) to the upper as well as lower position is 70-80 degrees relative to the initial (horizontal) position.

Thus, the design features of the “simulator-bucket” provide the ability to perform simple and accessible exercises for the patient due to the fact that the ball (10) is thrown directly from the body (and not from the position when it hangs on the lace from the bottom), and the patient can gradually increase the height of its tossing, and change the angle of the handle (2) relative to the container (1), thereby complicating the exercises. At the same time, it is possible to conveniently and quickly return the ball (10) to the container (1) of the “ladle simulator” by pulling the cord (9) by the loop (11) with a healthy hand.

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

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

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

In addition to using the “bucket simulator” in clinical practice, it can be widely used in the sports and fitness field, for example, when conducting classes with children.

Thus, the “bucket simulator” allows classes to develop the motor functions of the hands of patients in a neurological clinic due to the possibility of performing simple and accessible exercises for patients of varying degrees of difficulty, as well as the ability to conveniently and quickly return the ball to the capacity of the “bucket simulator” in in case he was not caught sick.

The use of a “ladle 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 “simulator-bucket” 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.
