Abstract

FIELD: medicine.

SUBSTANCE: invention relates to devices for treatment of a spinal curvature and correction of the individual's posture. Device for treatment of a spinal curvature comprises elements producing force impacts on elements of the spine. These elements are made in the shape of two units arranged on both sides of the spine. Each unit is assembled by serial alternation of ribs and rods pressed into the ribs bushings, and every rib of one unit is flexibly connected with a rib of the second unit. Rods are made of a material with the value of modulus of elasticity smaller than that of the ribs. Every rib includes a plate bent along the line separating a bent section of the rib from the rest of the plate attached to the bushing. Bent sections of ribs located in the upper part of spinal convexity are directed downward and to the patient's body. Bent sections of ribs located below the convexity of the spine, but on the side of the convexity are directed upward and to the patient's body, as well as bent sections of ribs located in the upper part of the back on the other side of the convexity of the spine. Bent sections of ribs arranged on the other side of the convexity of the spine, but below the said convexities are directed downward and to the body of the patient. There are slots in ribs for fixing of ends of belts, designed for pairwise fastening of every pair of these belts located in different blocks at the same height level on the patient's chest.

EFFECT: invention allows to exclude additional load on vertebral column.

Description

The invention relates to medicine, in particular to devices for treating curvature of the spine and correcting a person’s posture. Known devices for correcting a person’s posture in the form of special devices, vests, corsets, etc. In particular, a vest is known for correcting a person’s posture, comprising a flexible patch connected to its upper part by straps, the other ends of which are connected to the respective lateral sides of the patch, and an elastic belt attached to the lower part of the patch. The straps are equipped with length adjusters (RF patent 2142244, class A41C 1/00). The vest is put on in an upright position, and with the help of the strap length adjusters, the shoulders are pulled back and the back is aligned. The disadvantage of this vest is that such static tearing of the shoulder girdle and the thoracic spine creates discomfort, limits the natural mobility of patients, especially children. A posture corrector is also known, comprising a flexible pad connected in its upper part by straps, the other ends of which are connected to the respective lateral sides of the pad. The overlay has concavities at the top and sides, inside the middle contains springy stiffeners. The lining plane adjacent to the human back is provided with small holes (RF patent 211932, class A61F 5/03). The disadvantage of this posture corrector is that it does not have sufficient compensating capabilities, because springy stiffeners work only on bending, while when turning the upper body to the left and to the right, combined with the slope, at the same time, elastic torsion resistance is required. In addition, springy stiffeners are made of metal, which makes the structure heavier and complicates its intended use. The closest in technical essence to the claimed is a device for the treatment of curvature of the spine, presented by US patent (System for Spinal fnd Posture Examination and Treatment US Patent N. 6, 788? 968 B2) (Fig. Appendix), which consists in changing the position of the centers of mass of the head , chest and pelvis due to the fact that additional loads are fixed on the patient's body, leading to the correction of the spine and posture.

A disadvantage of this type of device is that the additional loads hung on the patient also load the spine.

The technical task of the invention is the creation of a device for the treatment of curvature of the spine due to such an application of forces that do not additionally load the spine.

The technical result is achieved in that the device contains elements that exert force on the elements of the spine, characterized in that these elements are made in the form of two blocks mounted on opposite sides of the spine, with each block being assembled by successive alternation of ribs and rods pressed into ribs and each edge of one block is connected by a flexible connection with the edge of the second block, while the rods are made of material with an elastic modulus less than that of the ribs, and each rib contains n a plate bent along the line separating the bent portion of the rib from the rest of the plate attached to the sleeve, in addition, the bent sections of the ribs located in the upper part of the bulge of the spine are directed downward and towards the patient’s body, the bent sections of the ribs located below the bulge of the spine, but on the side of the bulge of the spine, directed upward and towards the patient’s body, as well as the bent sections of the ribs located in the upper back on the other side of the bulge of the spine, and the bent sections of the ribs located on the other side from the convexity of the spine, but below this convexity, directed downward and to the patient’s body, also in the ribs there are slots in which the ends of the belts are fastened, designed for pairwise fastening of each pair of these belts located in different blocks, at the same height level on the patient’s chest.

The invention is illustrated by drawings, where in FIG. 1 shows a diagram of the loading of the spine when it is curved by scoliosis, FIG. 2 is a diagram of the application of forces from the proposed device for unloading the spine, FIG. 3 is a diagram of the installation of the proposed device on the patient’s body, in FIG. 4 is a diagram of a device for treating spinal curvature, FIG. 5 - sections KK and LL device for the treatment of curvature of the spine, in FIG. 6 - node: sleeve - rib, in Fig. 7 - pattern ribs mounted on the sleeve.

When the spinal column is curved, the back is divided into areas containing bulges (B) and not containing bulges. As a result, the muscles on the side of the bulges are in constant tension. The figure 1 shows that the force "P" acting on the axis of symmetry of the human body creates a moment Μ = PL, loading the spine. In this case, an increase in the moment “M” leads to an increase in the shoulder “L”, and an increase in the shoulder “L” leads to an increase in the moment “M”.

Thus, we have an unsteady process leading to more and more curvature of the spine.

To eliminate this situation, you need a device that would create a moment that opposes the moment "M". This is possible if a T1 force compressing the spine convexity region is applied, and T1 tensile forces are applied to the area located on the other side of the spine (Fig. 2). Then between the levels "GG" and "DD" these forces create a moment that opposes the moment "PL" and thereby leads to the restoration of posture.

A device for the treatment of curvature of the spine (Fig. 3) contains blocks 1 and 2 located on the patient’s back and interconnected by infinite flexible connections 3. Belts 4 are fixed to block 1, and belts 5 are attached to block 2. Belts 4 and 5 are fastened level by level between each other on the patient’s chest, thereby pressing blocks 1 and 2 to the patient’s back.

Blocks 1 and 2 contain the same ribs 6 and 7, but oriented in different ways (Fig. 4). The ribs 6, located on the side opposite the bulge of the spinal column in its upper part (at the level yy-dd (Fig. 2)), have free bent sections 8 (Figs. 5 and 6), which are directed upward and to the patient's body.

The ribs 6 contain plates 9 having slots 10 and 11. These plates 9 are bent along the line ff (Fig. 7), separating the free bent section 8 from the rest of the plate, welded or glued to the sleeve (12) (Fig. 6) .

Through slots 10 infinite flexible connections 3 are passed, connecting blocks 1 and 2 with each other. The end of the belt 4 is fastened in the slots 11 of the block 1, and the end of the belt 5 is fastened in the slots 11 of the block 2. The ribs 6 and 7 are made in the same way, but when assembled into blocks they are oriented in the opposite directions to each other. The ends 12 of the rods 13 are glued or vulcanized into the bushings 12 and are pressed in tightly. (Fig. 5) made of a material with a small elastic modulus. In this case, block 1 is assembled by successive alternation of ribs 6 and rods 13 to a height corresponding to the height of the zone between the sections g-d and d-d (Fig. 2), and below by alternating ribs 7 and rods 13 (Fig. 5) so that the free bent portion 14 is directed downward and towards the patient’s body. The rods 13 have in their middle part of the belt, the diametrical dimensions of which exceed the diametrical size of the bore of the sleeve, which ensures the fixation of the rod in the sleeve in the axial direction. Block 2 is assembled similarly to block 1, but with the reverse arrangement of the ribs. In the zone gg-dd, ribs 7 are installed with free bent sections 14 directed downward and to the patient's body, and below the ribs 6 are installed with free bent sections 8 directed upward and to the patient's body.

A device for the treatment of curvature of the spine is used as follows.

The device is worn on the patient, placing blocks 1 and 2 on the back so that blocks 1 and 2 are located on opposite sides of the spine. In this case, block 1 should be located on the side opposite to the bulge of the spine (Fig. 2 and Fig. 3). Then tighten belts 4 and 5 on the chest and abdomen. Since the artificial spines composed of ribs 6, 7 and rods 13 have pliable areas, these artificial spines are deformed when tightened, reproducing the topography of the back. When tightening the belts 4 and 5 between themselves, the free bent sections 8 and 14 of the ribs 6 and 7, respectively, are pressed against the patient's body with a force of "M" (Fig. 5). Since these sections are located almost vertically in the contact zone with the patient’s body, the force when tightening the Μ belts (Fig. 5) is much less than the T1 forces that load the patient’s back in a direction parallel to the vertical axis. However, unlike the Pettibon method, these forces will not additionally load the spine, since they are directed in opposite directions on blocks 1 and 2. But these forces create a moment directed in the opposite direction with respect to the moment created by the person’s weight. Thus, with an insignificant pressing force “M” it is possible to create a moment that can relieve the spine from the patient’s weight, which leads to unloading of the muscles, the formation of posture and the improvement of metabolism leading to recovery.
