Abstract

A finger trainer comprising a frame, characterized in that the frame is made of a cylindrical rod with a flat cutout in the center of its surface, the width of the cutout is equal to the width of a flat bar, one end of which is placed in a flat cut, a load is fixed on the bar in the form of a crimp ring made with the possibility of longitudinal movement along the bar, while the load is made, for example, of lead and securely fixed by, for example, a spring clip or a fixing screw.

Description

This useful model relates to medicine and is intended to restore motor activity after strokes, in the postoperative period, in the treatment of the consequences of cerebral palsy, in case of damage to peripheral nerves, vascular diseases, to restore the functioning of the hand and the development of fingers after various injuries to the hand.

In addition, the simulator can be used to develop mobility and strength of the fingers (especially for musicians and athletes), as a sports - competitive projectile and just as a toy to relieve nervous tension, because requires "inclusion" of attention.

Known finger simulator containing a housing of articulated plates and rings. In this case, the rings are made in the form of hollow cylinders and mounted in hinges. In addition, the casing strips in the middle have concave or convex cutouts where protrusions in the form of cones are installed, see RF patent No. 2471528, AV 23/16, from. 05/10/2011.

Also known is a "Toy simulator for the development of motor skills of the fingers", selected as a prototype, containing a frame in the form of a shell of sheet material, such as polyethylene, and, located in it, a filler, while the shell is divided into sealed sections having a size smaller the size of the pads of the fingers, distributed in an appropriate order and rising from one or both sides of the shell, air is used as a filler, with which each section is filled, each section is made with the possibility of being destroyed it pressing it with your fingers of one hand, at least the baby, see. RF patent №97267, A61N 1/02, A63V 23/16 from 27.03.2009.

However, the known device has limited use, because develops only carpal muscles of the fingers in a limited range, which is not enough for severe injuries of the hands.

The purpose of creating this useful model is to achieve a technical result to expand the functionality of the simulator for the development of fingers by ensuring the development of muscles such as the superficial flexor of the fingers, short palmar muscle and others.

The specified technical result is ensured by the fact that in the known device containing the frame, the frame is proposed to be made of a cylindrical rod with a flat cut in the center of its surface, the width of the cut is equal to the width of a flat bar, one end of which is placed in a flat cut. It is proposed to fix the load in the form of a crimp ring made with the possibility of longitudinal movement along the bar. In this case, the load is made of a material with a high specific gravity, for example, lead, is put on the bar and is securely fixed by, for example, a spring clip or a fixing screw.

The simulator is illustrated with graphic materials. Figure 1 presents the design of the simulator.

The simulator for fingers includes:

1. a cylindrical rod;

2. a flat cutout in the center of the surface of the cylindrical rod 1;

3. A flat bar installed at one end in a flat neckline 2;

4. the load, made in the form of a crimp ring, secured, with the possibility of longitudinal movement along the bar 3;

5. screw securing the load in a certain position.

The simulator consists of a cylindrical rod 1, with a flat central cutout 2 on the surface, the width of which is equal to the width of the flat strap 3. One end of the strap 3 is installed in the cutout 2. On the strap 3 is fixed load 4 in the form of a crimp ring, made with the possibility of longitudinal movement along the strap 3.

The load 4 is made of a material with a large specific gravity, for example, lead, is put on a flat bar 3 and is securely fixed on it, for example, with an interference fit or a fixing screw 5 or a spring clip.

Practical parameters of the components of the simulator.

The diameter of the cylindrical rod 1 may be 6-15 (+/- 1) mm. The length of the rod is 110-120 mm, and its material is wood (preferably hard hardwood), polymer, metal, for example steel, nickel and similar materials coated with a sweat-resistant coating. The cylindrical rod must have at least six longitudinal “notches” (ribs) with a height of at least 0.2 mm.

Flat bar 3 has a length of 190-200 mm and a cross section of 12x4 (+/- 1) mm. The material of the strap 3 is any, preferably wood or polymer, and it must have a means for reliably fixing the dynamic load (“load”) from the external end (opposite to securing it with a cylindrical rod through about 10 mm in at least 5 positions, which ensures fixation load 4 in five positions and five types of loads on the carpal muscles.

The cargo part 4 of the simulator is made of material with a large specific gravity, for example, lead, in the form of a parallelepiped (material density of more than 1.3 g / cm ³ ) with a rectangular hole in the middle equal to the cross section of a flat bar 3 with dimensions of at least 22x20x14 mm.

With the simulator work as follows.

In severe injuries and diseases of the muscles of the hands, the load 4 is installed on the straps 3 in a position close to the cylindrical rod 1. The patient takes the ends of the cylindrical rod 1 on both sides, with two hands, with thumb and forefinger, while the flat strap 3 has a long end out .

Then the patient has the middle or ring fingers from the bottom of the flat bar 3 and begins to alternately with these fingers raise and turn the flat bar 3 to the highest possible position.

The number of cycles of such a daily workout and their period is determined by the attending physician. In this case, the muscles of the superficial flexor of the fingers and the short palmar muscle develop.

After completing this exercise cycle, the load 4 is moved up the bar 3, thereby increasing the load on the carpal muscles and begin to perform a new cycle of exercises and so on until the muscles of the hand are completely rehabilitated.

The design of the simulator is new, previously unknown, which indicates its compliance with the patentability criterion - novelty.

The claimed utility model can be performed by any locksmith or carpentry workshop, which indicates its compliance with the criterion of industrial applicability.
