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 bed patients of a neurological clinic.

Violation of hand movements occurs in patients with a neurological clinic who have various organic brain lesions associated with poisoning, infections, injuries, and vascular diseases.

Of great importance for the effectiveness of recovery of both hand movements and the entire motor sphere of patients in a neurological clinic is the early start of classes to develop impaired movements.

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

The Rotational Trainer is known from the prior art (RATAY Rehabilitation, The Rotational Trainer was found on 01/05/17 on the Internet at http://ratay.kz/reabilitatsionnoe-oborudovanie7/trenazhery-dlya-hod-by-razvitiya-melkoj-motoriki / trenazher-rotatsionny-j-pronatsiya-supinatsiya-art-404-1-ya-mogu).

This simulator is designed to train the rotational movements 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 to develop impaired hand movements in patients with a neurological clinic are:

a) 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;

b) the ability to perform only one type of repeated similar movements of the arm, fixed on the stand of the simulator.

Also known from the prior art is a simulator for the development of joints of the upper limbs and the development of dexterity "Dexterity Development Simulator - AGT-800" (ReMed. Rehabilitation equipment, found on 01/05/2017 on the Internet at http://reamed.su/trenazhery- dlya-reabilitatsii / trenazher-razvitiya-lovkosti-agt-800).

This simulator is a panel with dimensions of 77 × 84 × 15 cm, on which there are nine buttons that are illuminated from the inside. During classes, the patient must press the luminous buttons, which are highlighted in a random mode. The device remembers the result of the patient’s training and each time forces him to perform movements more quickly.

An important feature of this simulator is that it contributes to the inclusion of the patient’s arm movement in a certain game activity and thereby transfers the movement process to another, more secure level of implementation, the work on which contributes to the faster recovery of impaired movements.

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

a) the difficulty of working with this device for bedridden patients, since during classes the patient should be in a standing or sitting position;

b) the impossibility of practicing with patients with impaired hand movements of a pronounced degree, since the simulator buttons are located at a great distance from each other;

c) the significant size of this simulator, which complicates its use for independent study of patients at home after discharge from the clinic.

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

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

a) the possibility of training with this device for bedridden patients in a neurological clinic;

b) the possibility of developing and restoring hand movements in patients with a neurological clinic with a pronounced degree of this disorder;

d) inclusion of the process of movements in attractive game activities for patients;

e) the possibility of studying with this device patients in a variety of conditions: in the ward, on a walk, etc .;

e) the possibility of self-study with this device after discharge of patients from the clinic at home.

The technical result of the claimed utility model ensures the implementation of the process of developing impaired movement of the arm of a lying patient in a comfortable position for him with a gradual increase in the complexity of the movements performed by the hand and with the possibility of independent studies.

This technical result is achieved due to the fact that the simulator-bracelet contains a case made of plastic, measuring 20-30 × 40-60 mm, height 15-25 mm, in the upper part of which are mounted a liquid crystal display and on / off switch of the simulator-bracelet, and inside the cases are located: the control unit of the simulator-bracelet, the battery and the speaker, and four control buttons are located on the sides of the case, while the strap, made of elastic plastic, is fixed to the bottom of the case of the simulator-bracelet 20-40 mm, on the upper surface of which to the left and to the right of the case of the trainer-bracelet 8-12 links-keys are rigidly fixed, each of which includes a box-shaped base made of plastic with a size of 15 × 15 mm to 20 × 20 mm, 10-20 mm high, inside of which are fixed: an LED, metal contact plates, two elastic elements, and a button-cap made of translucent plastic is fixed to the upper part of each base of the link-key, with the possibility of reciprocating movement, while located the battery inside the device’s case is electrically connected via a switch / switch to the control unit of the bracelet simulator, to which the LEDs and contact plates of each of the key links are connected via an electric cable, and a liquid crystal display, control buttons are electrically connected to the control block of the bracelet simulator and a speaker, while the wristband simulator is configured to operate in “light”, “medium” and “fixing” modes.

The simulator-bracelet for the development of impaired hand movements in bed patients of a neurological clinic (see figure 1-3) includes a plastic case (1) made in sizes 20-30 × 40-60 mm, height 15-25 mm, in the upper part which is mounted: a liquid crystal display (2) and an on / off switch (3) of the device. Inside the housing (1) are located: the control unit (15) of the device, the battery (16) and the speaker (5). On the surface of the housing above the speaker (5), a group of identical holes (4) is made. On the sides of the case (1) of the "simulator-bracelet" there are control buttons (6), two on each side.

The housing (1) of the device can be made either rectangular or in any other shape, depending on the shape and dimensions of the elements located outside and inside it.

A strap (7), made of elastic plastic, is fixed to the bottom of the case (1) of the device, with a width of 20-40 mm, at the ends of which a Velcro tape (8) is fixed, which secures the device to the patient’s wrist (see figure 3).

On the upper surface of the strap (7), to the left and to the right of the case (1), 8-12 key links (9) are rigidly fixed, each of which (see figure 4) includes: a box-shaped base (10) made of plastic inside which are fixed: LED (11), metal plate-contacts (12). two elastic elements (13), which can be made of any elastic material, for example, rubber. To the upper part of each base (10) movably, with the possibility of reciprocating motion, a button-cap (14) made of translucent plastic is fixed.

The base (10) has dimensions from 15 × 15 to 20 × 20 mm, a height of 10-20 mm, the thickness of the walls and bottom is 2-3 mm.

A battery (16) located inside the device’s case (1) is electrically connected via a switch / switch (3) to a control unit (15) by a device to which LEDs (11) and contact plates (12) located in each of the key links (9). Also, a liquid crystal display (2), control buttons (6) and a speaker (5) are electrically connected to the control unit (15) of the device.

On one of the sides of the housing (1) of the device there is an connector (not shown in the figures) electrically connected to the battery (16) for connecting an external charger.

After turning on the device with the on / off switch (3), the battery power (16) is supplied to the control unit (15) and other elements of the device (liquid crystal display (2), control buttons (6), etc.).

Then, using one of the control buttons (6), the device operation mode is determined, which determines the number of illuminated LEDs (11), and the other control button (6) sets the time for their illumination. In this case, all information is displayed on the liquid crystal display (2). After that, the next control button (6) turns on the LEDs (11).

Each LED (11) is turned off by pressing the button-button (14) located above it, which closes the contact plates (12), as a result of which an electrical signal is generated, which enters the control unit (15) with a device that turns off this LED (eleven).

If the patient does not have time to turn off the LED (11) at the set time, the speaker warning signal (5) is turned on. If necessary, a warning signal speaker can be turned off by one of the control buttons (6).

The device "Trainer-bracelet for the development of impaired hand movements in bed patients of a neurological clinic" works as follows.

Depending on the severity of violations of the patient’s arm movement, the work of the “simulator-bracelet” can be performed in different modes:

a) In case of gross and pronounced movement disorders, at the initial stages of training, an “easy” mode of operation is established, consisting in highlighting the minimum number (2-4) of adjacent key links (9), working with which does not require significant hand movements from the patient . In this case, the duration of the backlight is maximum and ranges from 3-5 s or more, since the patient's movements are difficult and slowed down.

b) For moderate and light movement disorders, an “average” mode of operation is established, which consists in highlighting all key links (9), which requires the patient to perform a significantly larger range of movements with his hand. In this case, the duration of the backlighting of the key links (9) is somewhat reduced and ranges from 2-3 s or more.

c) At the final stages of classes, the achieved results are consolidated and work is underway to restore the dynamic parameters of arm movements. In this case, the “fixing” mode of operation is established, which consists in the fact that when all key links (9) are highlighted, the duration of their illumination is further reduced, reaching up to 1-2 seconds.

Before starting classes, the specialist turns on the device by pressing the on / off button (3), as a result of which information on the transition of the device to working condition appears on the liquid crystal display (2). After that, the specialist, using the control buttons (6), sets the operation mode of the device depending on the severity of the violation of the patient's arm movements: “light”, “medium”, “fixing”.

Next, the specialist puts a “trainer-bracelet” on the patient’s wrist, fixing the strap (7) by means of Velcro tape (8) so that the “trainer-bracelet” fits tightly on the patient’s wrist, which is located in a convenient position, for example, on a pillow or on the patient’s chest.

After a specialist or patient presses the control button (6) associated with turning on the LEDs (11), they turn on and begin to highlight the key links (9), and the patient should turn them off with a healthy hand by pressing the button caps (14) of the links keys (9). If the patient does not have time to turn off the backlight of the link-key (9) at the set time, the warning signal of the speaker (5) is turned on. This process is repeated throughout the lesson, the duration of which is determined by a specialist, after which the “simulator-bracelet” is turned off by means of a switch / switch (3).

Gradually, as the patient achieves positive results, there is a transition to other modes of operation of the "simulator-bracelet", after which the work is carried out in the "fixing" mode.

Thus, the proposed device contributes to the inclusion of the patient’s arm movement in an attractive activity for him, and thereby transfers the movement process to another, more secure level of implementation, the work on which contributes to the faster recovery of impaired movements.

An important feature of the “bracelet simulator” is to provide the patient with both direct feedback characterizing the correct execution of the movements necessary during the lesson and delayed feedback characterizing the result achieved during the lesson.

Direct feedback is provided by: a) turning off the LED (11) of the key-link (9) after clicking on its cover-button (14); b) a warning sound signal emitted by the speaker (5), if the patient does not have time to press the lid-button (14) for a predetermined time.

Delayed feedback is provided by displaying on the LCD (2) the results of the lesson: the number of LEDs off (11), the number of LEDs (11) that the patient did not have time to turn off at a given time, etc.

One of the important features of the proposed device is its compactness, which allows the patient not to remove it from the hand after classes, so that he gets the opportunity to conduct independent classes on the development of impaired hand movements without resorting to outside help.

Along with bedridden patients of a neurological clinic, the “simulator bracelet” can be used to develop hand movements in patients with other diseases of the motor sphere: various injuries, the consequences of surgical interventions, etc.

Thus, the proposed device "Bracelet simulator for the development of impaired arm movements in bed patients of a neurological clinic" due to its compactness and ease of use allows you to include the process of impaired arm movement of a bed patient in an accessible and attractive activity for him, with a gradual increase in the complexity of the movements performed by the hand and provides the opportunity for independent study after discharge from the clinic.
