Description

The utility model relates to medical products, namely to devices for maintaining, replacing the support function and traction of the thoracic and lumbar spine and paravertebral muscles at these levels. The utility model can be used in orthopedics, neurology and traumatology, it allows simplifying and increasing the convenience of using the corset, expanding capabilities, improving the patient’s quality of life.

Anti-radiculitis belts and corsets are known from the prior art, for example, the device according to patent No. 2372058, (IPC A61F 5/02, published on November 10, 2009) - a lumbar corset, which includes a belt with a high back and two sides, equipped with fasteners made of textile pile fabric Velcro at their free ends. On the outer side of the back of the belt, in vertical pockets there are stiffening ribs made of elastic material. The device can only be used to maintain the supporting function of the spine, without the possibility of spinal traction. Existing anti-radiculitis corsets with stiffening ribs, which are used for back pain, have only a supporting function: they relieve stress from the spine and back muscles, and they do not have a traction effect, which limits their therapeutic capabilities.

Devices for spinal traction are also known, for example, in the device according to patent No. 2498788, (IPC A61F 5/01, published on November 20, 2013), an orthopedic set, including a rigid back, elastic straps, in which the back is made in the form of a pocket, into which a metal plate is inserted, a rigid recliner roller or recliner pneumatic roller is attached to the back in the form of a pocket, elastic straps with buckles and movable belt elements are also attached to the back. The reclining pneumatic roller is equipped with a cylinder and a cylinder fastening element, and also has a textile fastener on the front and back surfaces. The known kit has a pulling effect, but the pulling amplitude is small and is limited by the design features of the product.

A device is known according to utility model patent No. 189471, (IPC A61F 5/02, published May 23, 2019), in which the spine is pulled using a clamp, which limits the possibility of movement and causes inconvenience to the patient, because restricts movement in the thoracolumbar spine.

The closest in design and achieved result (prototype) is the device according to patent No. 2094028 (IPC A61F 5/02, published 10/27/1997), consisting of two belts - hip and chest, connected to each other through load-bearing telescopically sliding racks. Some of the racks are made in the form of a support sleeve attached to the hip belt and having a bottom, with a multi-tiered inflatable chamber installed coaxially in it, and the adjacent tiers of the chamber are connected to each other by central tubes. The lower tier is connected through a supply pipe and a shut-off device to a source of compressed gas. On the upper tier of the chamber there is a slider with a side protrusion that can slide along the sleeve, passing through the longitudinal guide groove of the sleeve and attached to the chest belt. Part of the load racks connecting the hip and chest belts of the corset are made in the form of a sleeve attached to the chest belt with a multi-tiered inflatable chamber that lifts the upper slider attached to the chest belt. The disadvantage of the known device, according to the applicant, is the complexity of its design, which makes it difficult to manufacture, the uneven impact on the spine (stretching), due to the fact that only part of the load racks are made in the form of a sleeve with an inflatable chamber attached to the chest belt, and also difficulty of operation.

The objective of the proposed utility model is to expand its functionality while simplifying the design of the corset.

The problem is solved by making an elastic and flexible base of the belts from sheet metal wrapped in fabric, and the load racks are in the form of gas lifts connecting the chest and lumbar belts, attached to the plates by means of bolts, with the ability to adjust the length of the gas lifts.

The technical result consists in combining in one device two functions, two forces acting on the back muscles and the patient’s spine - supporting and, at the same time, stretching, which allows expanding the therapeutic capabilities of the corset, increasing the preventive, therapeutic and rehabilitative effects of the corset on the thoracic and lumbar regions spine while simplifying the design and use of the corset.

The essence of the utility model is that the corset, consisting of two belts - chest and thigh, connected to each other through load racks, has, as a rigid base of each belt, an elastic and flexible strip of sheet metal, wrapped in cotton fabric, reinforced at the folds with additional fabric layer. The load racks are made in the form of pneumatic gas lifts (gas lift, pneumatic cartridge, or gas spring), which are a sealed cylinder with gas pumped into it, in which, under the influence of this gas, a piston connected to a rod moves freely; and the sliding bearing and oil seal ensure their sealed movement . Load racks are secured to the belts with flat fasteners using bolts and located around the circumference of the belts, at an equal distance from each other (optimally - 8 pieces per product). The racks, made in the form of gas lifts, can be adjusted in length and fixed in a given position. Moreover, all racks have a stretching function, which provides a more uniform effect on the spine than in the prototype.

The orthopedic corset contains a hip belt 1 and a chest belt 2, connected by load racks 3. The base of each belt is made in the form of an elastic and flexible strip of sheet metal 4 with a width of 100 mm and a thickness of 0.45 mm (Fig. 1, 2,). The tin strip of the belt is wrapped in cotton fabric, reinforced at the folds with an additional fabric layer. The load racks 3 are made in the form of pneumatic gas lifts (Fig. 3). Each rack contains a support sleeve 5 with a rod 6, connected by means of a fastening element 7 (Fig. 1, 2, 4), secured to the hip belt 1 and chest belt 2, using bolts 8 (Fig. 1, 2, 4). Sleeve 5 is made of hard, durable material, for example, steel . In the sleeve, in the guide grooves 9, a rod 6 is installed coaxially with a piston 10 equipped with an o-ring 11 (Fig. 3). The guide grooves 9 of the rod 6 contain a sliding bearing 12 and an oil seal 13, facilitating its movement in the cavity of the sleeve. There is a space 14 in the bottom part of the sleeve. The sleeve, initially filled with compressed gas, is equipped with a seal 15 in the upper part. On the outer side of the bottom of the sleeve 16 there is a fastening means in the form of a cylinder 17 with a side non-through mounting hole 18 (Fig. 3). A similar fastening means is made at the end of the rod 6. Each belt is equipped with Velcro fasteners 19 and fastex fasteners 20 (Figs. 1,2,7,8).

When using a corset, there is no need for a compressor to pump gas into the sleeve, because This was done initially during the manufacture of the gas lift.

Gas lifts are produced commercially; they are designed for raising and lowering moving elements, with fixation in a given position. The damping effect is achieved due to inert gas. contained in the cavity of the cylinder under pressure. The gas spring is refilled once during assembly. The proposed orthopedic corset is immediately ready for use.

The device functions as follows:

The corset, consisting of two belts, is attached to the patient’s body using Velcro fasteners 19 and fastex fasteners 20 (Figs. 1, 2, 7,8). One belt is attached in the lumbar region, with emphasis on the anterior and posterior spines of the iliac wing, the other - along the armpits (Fig. 1, 2, 7, 8). The load rack 3, in the form of a gas lift, is attached to the upper 1 and lower 2 belts (Fig. 1, 2, 7, 8), with fasteners fixed to them (Fig. 3,4), through a side blind mounting hole 18, which located in the bottom of the sleeve 5 and at the end of the rod 6, respectively. The load rack (gas lift) is fixed on belts 1 and 2 so that the rod 6 with piston 10 is immersed in the gas lift sleeve 5 by 1/3 of the total length of the rod, to create the effect of extension and the power reserve of the rod necessary for tilting the body when the patient wears a corset. The length of the rod 6 is set individually, according to the patient's height, by connecting the rod 6 with a threaded pin (Fig. 5) using a threaded coupling (Fig. 6) and fixing it in the desired position (1/3 of the total length of the rod). In this state, the corset has a supporting effect on the thoracic and lumbar spine, achieving the function of traction of the paravertebral muscles in the thoracic and lumbar spine.

The proposed orthopedic corset has both a supporting function (due to supporting posts rigidly fixed on an elastic and flexible basis) and a spinal traction function (due to adjusting and fixing the length of the guides in the selected position), thus achieving its therapeutic effect, which ultimately As a result, it reduces (in intensity and duration) the pain syndrome in dorsopathies and radiculopathies, and, as a result, reduces single and course doses of medications taken, shortens the time spent on treatment, minimizing the occurrence of side effects.

The applicant produced a prototype corset and tested it on patients suffering from lower back pain. (The position of the manufactured corset on the patient’s body is shown in the photographs: Figs. 7 and 8).

An example of a specific application of the proposed corset.

Patient K., 37 years old. He was admitted with complaints of pain in the lumbar spine with projections of pain along the posterior surface of the right lower limb, limitation of movements in the lumbar spine due to pain. She has been sick for the last week after lifting heavy objects. He was treated with non-steroidal anti-inflammatory drugs and used a lumbosacral anti-radiculitis corset with stiffening ribs - without effect. The neurological status showed signs of radiculitis of the first sacral root on the right. According to MRI of the lumbosacral spine, a herniated intervertebral disc of 6 mm with lateralization to the right is visualized. The patient was fitted with a corset of the design described above, adjusted to his height, using gas lifts. After using the corset for 4-6 hours a day, the patient began to notice a decrease in pain and an increase in the range of painless movements in the lumbar spine. And after a week, the painful manifestations regressed, the amplitude of painless movements in the spine was restored.

The proposed orthopedic corset can be made from available materials, is simple and easy to use and has greater technological capabilities in treatment and prevention, compared with known devices, resulting in a reduction in treatment time and an increase in the effectiveness of prevention of painful muscle conditions in the thoracic and lumbar spine.

Thus, the problem facing the utility model has been solved.
