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.

Also, from the current level of technology, the device “Bracelet simulator for developing impaired arm movements in bedridden patients of a neurological clinic” is known (Patent RU 175412 U1, publication date 12/04/2017).

Structurally, this device is a bracelet fixed on the patient’s hand with impaired movement, containing a control unit and 8-12 keys with LEDs that light up in a certain sequence, and the patient must press the backlit keys, while turning the arm with the bracelet to an appropriate angle.

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 use with bedridden patients who are difficult to access with other simulators;

b) this device does not provide the ability to develop movements of the hand and fingers;

c) the technical complexity of this device, which includes various electronic components: control unit, LEDs, battery, etc.

Also, from the existing level of technology, the device "Training simulator for classes on the development of motor functions of the hands in patients of a neurological clinic" is known (patent RU 182947 U1, publication date September 6, 2018).

Structurally, this device is made in the form of a mug with a thickened bottom, in the center of which there is a hole with a diameter of 10-15 mm with rounded edges, through which a cord with a ball fixed on it is stretched.

During classes with the "simulator-circle", the patient, holding his hand with a movement disorder, throws the ball up by moving his arm with this device, and then tries to catch the ball with the "simulator-circle".

If the patient could not catch the ball, then he returns it inside the "simulator-circles" by pulling the cord with the ball with his healthy hand, and then continues to carry out the exercise further.

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 simulator provides the ability to primarily develop movements of the elbow and shoulder joints of the hand, but does not provide the ability to develop movements of the hand and fingers;

b) the difficulty of holding the device for patients with impaired movements of the fingers due to the inability to fix the "simulator-circles" in the patient's hand through the strap.

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

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

a) providing the possibility of developing not only the movements of the elbow and shoulder joints of the hand, but also the movements of the hand and fingers of the patients;

b) the absence of the need to keep the patient "simulator-bracelet" due to the fact that during training it is fixed on the patient's hand;

c) ensuring the availability of classes with a "simulator bracelet" for patients with impaired motor functions of the hands of varying severity;

d) the possibility of implementing exercises of varying degrees of difficulty;

e) ensuring the possibility of a convenient and quick return of the ball to the patient’s hand if it has not been caught;

e) the simplicity of the design of the "simulator-bracelet", contributing 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 the expansion of the functionality of the "Simulator-circles for classes on the development of motor functions of the hands of patients in a neurological clinic," provided by the structural elements of the claimed "simulator-bracelet", allowing classes to develop motor functions of the hands, with the possibility of developing movements of both the elbow and shoulder joints, as well as movements of the hand and fingers, while providing the ability to perform with a "simulator bracelet »Exercises of various degrees of difficulty, as well as convenient and quick return of the ball to the patient’s hand.

This technical result is achieved due to the fact that the "simulator-bracelet" contains a strap fixed on the wrist of the patient’s wrist, in the center of which a plastic plate 3-5 mm thick is fixed, at the end of which a perpendicularly arranged circular ring with an outer diameter of 30- 40 mm, through which a cord is stretched with a ball with a diameter of 40-60 mm fixed on it, and the other end of the cord is made in the form of a loop, in front of which a limiter is installed.

In the preferred embodiment of the "simulator-bracelet" the strap is made of elastic plastic, has a width of 25-35 mm, and a Velcro tape is fixed at its ends.

In a preferred embodiment of the "simulator-bracelet", the plate is made in the form of an isosceles trapezoid with a height of 45-60 mm and a wide part with a size of 30-40 mm.

In a preferred embodiment of the "simulator-bracelet" the diameter of the cross section of the ring is 8-12 mm

In a preferred embodiment of the "simulator-bracelet" the diameter of the lace is 2-4 mm, and its length is 1200-1500 mm.

In a preferred embodiment of the “trainer-bracelet”, the stopper is a plastic washer 3-5 mm thick, the inner diameter of which is equal to the diameter of the cord, and the outer diameter exceeds the diameter of the hole in the ring by 1.5-2 times.

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

In FIG. 1 - view of the "simulator-bracelet" on the patient's hand;

In FIG. 2 - view of the "simulator-bracelet" from above (without lace and ball);

In FIG. 3 is a side view of a “trainer-bracelet” (without a lace and a ball).

The claimed "simulator-bracelet" (see Fig. 1-3) is a strap (1) in the center of which a structural element made of plastic is fixed, consisting of a plate (2) with a ring (3) through which the cord (5) is stretched with a ball fixed on it (6).

The strap (1) is made of elastic plastic, has a width of 25-35 mm, and a Velcro tape (4) is fixed at its ends, which ensures its reliable fixation on the patient’s wrist.

The plate (2) has a thickness of 3-5 mm and is made in the form of an isosceles trapezoid with a height of 45-60 mm and a size of a wide part of 30-40 mm, and at the end of the narrow part of the plate (2) there is a perpendicularly arranged ring (3) with an outer diameter of 30 -40 mm, which has a circular cross section with a diameter of 8-12 mm, providing ease of sliding of the lace (5) through the hole in the ring (3).

The wide part of the plate (2) is rigidly fixed (for example, by means of adhesive bonding or rivets) to the central part of the strap (1).

The ball (6) used in the course of training with the “trainer-bracelet” is made of elastic plastic and is hollow, and its diameter is 40-60 mm.

As a lace (5), a braided synthetic rope with a diameter of 2-4 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 10/05/2018 in the Internet at http://2029863.ru/kruchennaya-veryovka).

The length of the lace (5) is 1200-1500 mm, and its fastening to the ball (6) can be carried out in various ways, for example, by gluing.

The other end of the lace (5) is made in the form of a loop (7), which provides the convenience of holding the lace (5) with the patient’s healthy hand during training with a “bracelet simulator”.

To prevent accidental slipping of the loop (7) through the hole in the ring (3) during training with a “trainer-bracelet”, a stopper (8) is installed on the cord (5) in front of the loop (7), which is a 3-5 mm thick plastic washer , the inner diameter of which is equal to the diameter of the lace (5), and the outer diameter exceeds the diameter of the hole in the ring (3) by 1.5-2 times.

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

Before the start of the lesson, the specialist puts on a “trainer-bracelet” on the patient’s wrist with impaired movement, fixing it with a Velcro tape (4).

 In this case, the “simulator-bracelet” should be located on the patient’s wrist in such a way that the ring (3) is in the area of the beginning of the palm of the hand, so when pulling the cord (5), the ball (6) rests on the ring (3) and then it turns out in the center of the palm of the patient.

At the same time, a loop (7) of a cord (5) is located in a healthy hand of a patient, and a healthy hand of a patient holding a loop (7) is located near a hand with a “bracelet exercise machine”.

The exercise performed by the patient with the "simulator-bracelet" includes the following movements:

a) toss the ball (6) up to a small height, by moving the hand;

b) catch the ball (6) with your hand.

If after performing the above actions the ball (6) was caught, then the patient continues to carry out the exercise further.

If the ball (6) has not been caught, the patient returns the ball (6) to the palm of the hand, by pulling the cord (5) with the healthy hand over the loop (7), after which the exercise continues.

As the patient achieves positive results in the development of motor functions of the arm, complication of the exercise performed with the “simulator-bracelet” is carried out by gradually increasing the height of the tossing of the ball (6).

Thus, the design features of the "simulator-bracelet" provide the ability to perform movements that ensure the development of hand movements in the elbow and shoulder joints, as well as movements of the hand and fingers.

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

After mastering the use of the "simulator-bracelet" 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 “simulator-bracelet” 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, the consequences of surgical operations, etc.

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

Thus, the “bracelet simulator”, due to its design features, allows classes on the development of motor functions of the hands, with the possibility of developing movements of both the elbow and shoulder joints, and movements of the hand and fingers, while ensuring the ability to perform with a “bracelet simulator” »Exercises of various degrees of difficulty, as well as convenient and quick return of the ball to the patient’s hand.

The use of a “bracelet 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 bracelet” 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.
