Description

[0001] The utility model relates to the field of medical technology, namely to means of positioning and supporting the user's body, mainly children and adults with musculoskeletal disorders, and can be used in rehabilitation, orthopedics and care.

[0002] Corrective corsets are medical devices used to support, stabilize, and relieve the spine in cases of musculoskeletal disorders. They help correct deformities, stabilize the vertebrae, reduce stress on muscles and joints, reduce pain, and speed up recovery during rehabilitation after injuries or surgeries.

[0003] A known technical device is a support for disabled children (RU 146597, cl. A61F 5 / 37, 2014), comprising a frame and a support unit mounted thereon. The support unit is adjustable in at least three directions. The support unit consists of a seat and a backrest and is adjustable for backrest angle, depth, and width using retractable parts. The width of the seat support unit is adjusted using removable modules of varying thickness.

[0004] The seat support unit is depth-adjustable. The lying support unit is width-adjustable, with adjustable backrest angle and footrest angle. A multifunctional system of belts and foam modules (cushions) has been added, as well as a height-adjustable abductor. Individual support elements for children with disabilities are designed as a structure of interchangeable modules.

[0005] Due to the fact that the structure is rigid, it does not provide the necessary fixation of the patient's body due to the fact that it is not able to cover the user's body from several sides at the same time - from below, from behind and from the sides - just like the outer Matryoshka doll covers the inner one.

[0006] The closest analog to the claimed device is the Stabilo GRANDE corrective corset-mattress with the BEANSEAT STABILO SYSTEM vacuum positioning system, a modeling chair-ottoman designed to stabilize the torso, head, and limbs of patients with cerebral palsy and other developmental disabilities. The design consists of a two-layer shell, the lower layer of which is made of neoprene, and the upper layer is jersey. The shell is filled with a filler of polystyrene granules. The shell is equipped with a vacuum valve for air removal and shape fixation (https: / / vermeiren.ru / catalog / Korseti_STABILO / korrigiruyushchiy_matras_stabilo_grande / ?ysclid=mqgh771wv390739926).

[0007] However, the known design is not functional enough, due to the amorphous shape of the pouf without a given enveloping geometry and does not provide the possibility of its use in strollers.

[0008] The problem that the utility model is aimed at is the creation of a corrective corset-chair that is free from the shortcomings of known designs.

[0009] The technical result of the utility model is the expansion of the functionality of the corrective corset-chair due to the possibility of individual anatomical adaptation of the shape with simultaneous stabilization of the pelvis and torso, abduction of the hips by means of an integrated abductor and freedom of movement of the upper limbs.

[0010] The technical result is achieved in that the corrective corset-chair contains a sealed elastic shell, a filler in the form of expanded polystyrene granules placed inside the shell, and a vacuum valve for removing air from the internal volume. According to the utility model, the sealed elastic shell is made with a predetermined shaping geometry of the enveloping type and has a contour in plan formed by sequentially connected zones of variable width: a head and neck support zone, a central zone covering the shoulder girdle, thoracic and lumbar regions, made with a lateral expansion in the form of symmetrical protrusions on both sides of the vertical axis of the shell, ensuring coverage of the user's body, a pelvic support zone, in the lower part of which an abduction zone in the form of a conical protrusion is formed along the vertical axis of the shell. The central zone is connected to the head and neck support zone and the pelvic support zone by means of smooth constrictions

[0011] The expanded polystyrene granules are subjected to anti-friction treatment to ensure their free movement within the sealed elastic shell.

[0012] The lateral expansion of the central zone of the shell is made with a width that ensures coverage of the user's body in accordance with his anatomy and is sufficient to stabilize the position of the body.

[0013] Head and neck support area, designed in the form of a rectangular outline rounded at the top.

[0014] The implementation of the enveloping geometry with a pre-set contour ensures that the shape of the shell matches the anatomical contours of the user's body even before vacuuming, which reduces the time required to prepare the product for use and ensures the correct positioning of the user in the corset-chair.

[0015] The creation of the shell contour by means of sequentially connected zones with variable widths allows for the differentiated distribution of the filler among the functional zones of the body, providing the necessary degree of coverage and support in each of them.

[0016] The presence of a head and neck support zone ensures the fixation of the head and cervical spine in a physiologically correct position, preventing their unwanted displacement during use.

[0017] The presence of a central zone with lateral expansion in the form of symmetrical protrusions on both sides of the vertical axis provides coverage and support for the shoulder girdle, thoracic and lumbar spine, and the lateral protrusions eliminate lateral displacement of the user's body, stabilizing his position in the frontal plane.

[0018] The contour of the shell is created with a smooth narrowing at the junction of the zones, which ensures an anatomically correct transition between zones, corresponding to the natural contours of the body in the neck, back and lumbar region, and prevents the filler from shifting between zones during vacuuming.

[0019] The presence of a pelvic support zone ensures its fixation in the correct position, which is a support point for the entire spinal column.

[0020] The presence of an abduction zone in the form of a cone-shaped protrusion located along the vertical axis of the shell in the lower part of the pelvic support zone ensures the spreading of the user's lower limbs at the hip joints - abduction, which is a necessary condition for the correction of a number of disorders of the musculoskeletal system.

[0021] The utility model is illustrated by a drawing, which depicts a template of an elastic shell made with a predetermined shape-generating geometry.

[0022] The utility model is explained by the following positions.

[0023] 1 - vertical axis of the sealed elastic shell;

[0024] 2 - head and neck support zone,

[0025] 3 - central zone, covering the shoulder girdle, thoracic and lumbar regions;

[0026] 4 - protrusions in the form of lateral extensions of the central zone 2, located symmetrically on both sides of the vertical axis 1 of the shell;

[0027] 5 - pelvic support zone;

[0028] 6 - ​​abduction zone in the form of a cone-shaped protrusion, located in the lower part of zone 5 of pelvic support along the vertical axis 1 of the shell.

[0029] The hermetic shell can be made of chloroprene rubber with a textile coating, which ensures airtightness, flexibility, and elasticity, resistance to mechanical stress and deformation, and comfortable interaction with the patient's body. The seal is ensured by the shell's base material, sealed butt seams, and a sealed vacuum valve connection for removing air from the shell's interior.

[0030] The corset-chair can be produced in various sizes corresponding to the anthropometric parameters of the user, which ensures its use for both children and adults.

[0031] Before using the corrective brace chair, the vacuum valve (not shown in the figure) is opened, bringing the shell into a soft, flexible state. This allows the foamed polystyrene granules to move freely within the shell thanks to the antifriction treatment on their surface. The pre-set shaping geometry of the enveloping shell ensures correct initial positioning of the user without additional adjustments.

[0032] The user is placed in the corset-chair. The shaping contour of the shell directs the body's positioning through its functional zones: head and neck support zone 2 stabilizes the head and cervical spine; central zone 3 with lateral extensions 4 in the form of symmetrical protrusions covers the shoulder girdle, thoracic and lumbar regions, providing lateral support for the torso; pelvic support zone 5 stabilizes the pelvic girdle as the support point of the spinal column; abduction zone 6, in the form of a conical protrusion, is located between the user's thighs, providing hip abduction.

[0033] The operator manually distributes the filler, creating a depression under the pelvis, lateral torso supports, and, if necessary, creating asymmetrical support according to the user's individual characteristics. Smooth tapers between zones 2, 3, 5, and 6 prevent unwanted filler flow and maintain a differentiated distribution of granules across the zones.

[0034] After the formation is complete, air is removed from the internal volume of the shell through a vacuum valve. The expanded polystyrene granules are fixed in place, forming a rigid-elastic structure that precisely follows the individual anatomical contours of the user's body. The corset-chair maintains its shape throughout its entire service life.

[0035] If it is necessary to change the shape, the valve is opened again, which returns the product to a plastic state and allows for reformation.

[0036] Thus, the use of a corrective corset-chair provides:

[0037] individual anatomical adaptation of the shape to the body of a specific user without the use of rigid structural elements;

[0038] stable fixation of the pelvis, torso and head in a physiologically correct position;

[0039] correction of the position of the lower limbs in the hip joints due to the abduction zone;

[0040] Formation of lateral supports of the torso without limiting the mobility of the upper limbs;

[0041] the ability to be repeatedly reformed in accordance with the dynamics of the user's state;

[0042] Compatible with strollers due to the compact shape of the product.

[0043] Versatility: The corset-chair can be used for both children, including those placed in strollers, and adults. The product's dimensions are determined by the individual user's anthropometric parameters.
