Description

The invention relates to medical equipment, namely to traumatology, orthopedics and neurosurgery, and can be used for the treatment and prevention of deformities, in the treatment of diseases and injuries of the lumbar spine.

Physiological posture and the correct position of the lumbar spine are associated with maintaining lumbar flexion - lordosis (Normand M.S., M. Descarreaux, C. Poulin, et al. Biomechanical effects of a lumbar support in a mattress // J Can Chiropr Assoc. 2005 Vol. 49, No. 2. P. 96-101; Harrison DD, Harrison SO, Croft AC, et al. Sitting biomechanics, part II: optimal car driver's seat and optimal driver's spinal model // J Manipulative Physiol Ther. 2000. Vol.23, No. 1. P.37-47). Muscle fatigue during sedentary work, as well as other activities, leads to a flattening of the lumbar curve, which causes overload of the intervertebral discs, ligaments and joints and causes pain in the lower back. Also, the disappearance of lumbar lordosis and the formation of reverse curvature - lumbar kyphosis, is observed when working in an inclined position, which is accompanied by lower back pain. Prolonged upright position is often accompanied by increased lumbar lordosis due to weakness of the abdominal muscles. This situation causes overload of the intervertebral joints and is manifested by pain. Most of the seats in the room, transport have either a direct supporting back, or a weak bend towards the sitting person, or vice versa, a bend in the opposite direction, which in the vast majority of cases does not correspond to the specific lumbar bend sitting on such a person's chair. This leads to the fact that in a sitting position, even in the lumbar corset, with support on the back of the chair, correction of the lumbar bend - lordosis decreases and disappears.

There are various bolsters that are used to create support for the lower back when sitting in chairs (patent RU 46428 U1, 07/10/2005; US D637435 S, 05/10/2011). They help maintain lumbar flexion. A significant disadvantage of the known rollers is that they are additional devices that you want to carry.

The cushion rollers that can be worn on the lumbar spine are deprived of this drawback (patent US 2005/0137509 A1, 06/23/2005; WO 2006/019756 A2, 02/23/2006). They are used to facilitate the maintenance of the lumbar curve and reduce the load on the muscles of the lumbar spine. A significant disadvantage of the known backing rollers is that they do not always correspond to the degree of bending of the lower back of the user. In addition, the known backing rollers do not have the function of external immobilization, that is, they do not allow limiting the mobility of a certain spine, which significantly reduces the degree of their therapeutic and prophylactic effect on the lumbar spine.

This drawback is deprived of lumbar corsets, lumbar belts and bandages, which are intended for therapeutic and prophylactic effects on the lumbar spine by external immobilization, that is, restrictions on the mobility of this spine (patents RU 2175219 C2, 10.27.2001; RU 2268024 C1, 01.20.2006 ; US 2009/0118655 A1, May 7, 2009). They consist of their outer wide belt, which can have a different degree of stiffness, depending on the materials used. To reinforce stiffness, additional hard inserts are used (patents RU 2268024 C1, 01.20.2006; RU 2175219 C2, 10.27.2001; US 2005/0137509 A1, 06.23.2005; US 2009/0118655 A1, 05.05.2009). To enhance the effect of immobilization and a more comfortable wearing of a corset, rigid inserts are modeled by the user in the form of his own body.

A significant drawback of the known lumbar corsets and bandages is the lack of accuracy in modeling rigid inserts according to the configuration of the body. This is due to the fact that manual modeling of these inserts is not always adequate and accurate. In addition, corset users often forget about the mandatory procedure for modeling a corset, which leads to its misuse and reduced effectiveness. The constant use of the lumbar corset, especially in the sitting position, leads to mechanical stress on the rigid inserts and the loss of the necessary bend over time. In the event that the rigid inserts of the corset have increased rigidity, this leads to a decrease in comfort when wearing the corset, which excludes its long-term use. The lack of rigidity of the corset, on the contrary, reduces its healing and prophylactic properties. Also, existing lumbar corsets do not significantly affect the abdominal muscles, which is important because their tension along with the work of the lumbar muscles stabilizes the lumbar spine (McGill SM, Karpowicz A., Fenwick CMJ Ballistic abdominal exercises: muscle activation patterns during three activities along the stability / mobility continuum // J Strength Cond Res. 2009. Vol.23, No. 3. P. 898-905; Watanabe S., Eguchi A., Kobara K., et al. Influence of trunk muscle co-contraction on spinal curvature during sitting reclining against the backrest of a chair // Electromyogr Clin Neurophysiol. 2008. Vol. 48, No. 8. P. 359-365).

Known orthopedic corset (patent RU 2189203 C2, 09/20/2002), which is selected as a prototype. The well-known orthopedic corset consists of a belt, half-belts, stiffeners and elastic inserts. The belt is made in the form of a flexible strip with tapering ends along which "Velcro" is sewn, and stiffening ribs are sewn in the middle part of the belt, inserts are located between them. Near stiffeners the ends of half-belts are sewn, made of knitted rubber tapes folded in half. Velcro is also sewn on the ends of the half-belts. The well-known orthopedic corset allows for effective treatment and the correction of diseases of the spine.

A disadvantage of the well-known orthopedic corset is that it uses plastic or metal inserts. Plastic inserts during the operation of the orthopedic corset are slightly deformed and therefore do not accurately follow the contours of the body, which reduces the effectiveness of the treatment. The use of metal inserts implies that the patient must independently model them with his hand. In this case, the modeling of the inserts is difficult to carry out carefully. As a result, the bend of the inserts correspond to the individual bend of the human lower back very approximately. In addition, patients often do not perform insert modeling due to ignorance or forgetfulness. All this reduces the effectiveness of the treatment.

The objective of the invention is to increase the effectiveness of treatment.

The task is achieved by a lumbar posture corrector-corset, which consists of a belt made in the form of a flexible strip, half-belts made of knitted rubber ribbons folded in half, one ends of which are sewn to the belt in the lumbar region, and Velcro, rigid inserts are sewn on the other ends, located in the lumbar and abdominal region and made of fiberglass impregnated with polyurethane resin, and a removable lumbar cushion equipped with Velcro, with rigid inserts located in the abdominal region Essa, mounted on a flap made in the form of a flexible strip, which, using Velcro sewn on one of its ends, is attached to one of the half-belts.

Achieving the claimed result, namely, increasing the effectiveness of treatment is achieved due to the fact that the rigid inserts are located not only in the lumbar region, but also in the abdominal press, and are made of material (fiberglass impregnated with polyurethane resin), which is able to be modeled, and, in addition , the lumbar posture correction corset is additionally equipped with a replaceable lumbar roller.

Figure 1 presents a schematic representation of the lumbar corset-posture corrector in two projections.

Figure 2 presents a schematic representation of a lumbar corset-posture corrector in a worn and fastened position on a person in a lateral projection when the user is standing.

Figure 3 presents a schematic representation of a lumbar posture corrector corset when put on and fastened on a person in a lateral projection when the user tilts forward.

Figure 4 presents a schematic representation of a lumbar posture corrector corset when put on and fastened on a person in a lateral projection when the user is sitting on a chair.

The lumbar posture correction corset consists of a belt (8), rigid inserts (3, 5), half-belts (2, 4), at the ends of which Velcro is sewn (1, 7), a flap (10) with Velcro (11) and a removable lumbar roller (6) with Velcro (9).

Apply a lumbar posture correction corset as follows. At the first use of the corset, the user, holding the ends of the belt, places its middle part on the lower back in the area of spinal pathology. Then, holding both half-belts with both hands, pull them together and, covering the whole body, fasten the half-belts by attaching Velcro (1) to the Velcro (7). Next, the user determines the place on one of the half-belts, to which, after unfastening the Velcro (1) and (7) using Velcro (11), attaches the flap (10) so that the rigid inserts (5) are located in the abdominal area. Then, once again, holding both half-belts with both hands, pull them together and, covering the entire body, fasten the half-belts by attaching Velcro (1) to the Velcro (7). Thus, the user's torso is tightened, while the rigid inserts (3) are located in the lumbar region, and the rigid inserts (5) are located in the abdominal region. Since initially rigid inserts (3, 5) have a soft consistency, due to pressure due to pressure, the shape of the rigid inserts (3 and 5) is modeled individually according to the shape of the body.

To maintain shape and stiffen the inserts, the lumbar corset-posture corrector is moistened by spraying it with water. The polyurethane resin of the inserts (3) and (5) after wetting enters the polymerization reaction, which leads to the appearance of stiffness of the inserts and the preservation of their individual forms. After the lumbar corset, the posture corrector on the body, has dried, it can be removed by unfastening the Velcro (1) and (7). Thus, the corset takes on a strictly individual form in the body of the user.

Replaceable lumbar roller (6) at the request of the user with the help of Velcro (9) is attached to the lumbar region.

Unlike the prototype, in this case, the hard inserts are located not only in the lumbar region, but also in the abdominal press, which limits excessive flexion in the lower back and prevents unwanted overload of the lumbar spine. In contrast to the prototype, rigid inserts are made of material that is capable of being modeled, which contributes to the fact that the bending of rigid inserts almost exactly corresponds to the individual bending of the human body in the lumbar region and abdominal region. In addition, the lumbar posture correction corset is additionally equipped with a replaceable lumbar cushion, which allows you to create the necessary support for the lumbar support in the sitting position, as well as in the supine position, including during sleep (figures 2, 3, 4).

The materials used for the manufacture of a lumbar corset - a posture corrector, are standard and their characteristics depend on the destination (prophylaxis or treatment), on the patient's parameters (age, girth in the belt, etc.), as well as on the characteristics of the disease and injury of the lumbar spine . Replaceable rollers can be of different sizes depending on its thickness, allowing the user to choose the most suitable, corresponding to his size, degree of lumbar bending, type of activity, seat structure, etc. Rigid inserts made of fiberglass impregnated with polyurethane resin. A similar principle is applied in bandages intended for the manufacture of immobilizing dressings in traumatology and orthopedics (http://www.senikitin.ru/literature/immobilise-new-tech.html). When water is applied to the bandage, the resin polymerization reaction is activated, as a result of which the dressing hardens. In this case, the full strength of the material occurs after 30 minutes.

The author has created and tested a variant of the claimed lumbar corset-posture corrector. It was made of the following materials: knitted rubber, Velcro, fiberglass impregnated with polyurethane resin, as well as a removable roller made of dense foam. The treatment showed that this lumbar posture corset-corrector effectively carried out posture correction and maintaining the correct position of the body throughout its use, both during sedentary work, physical labor, and during horizontal rest. Against the background of the use of this corset, a rapid regression of pain in the back was noted at the beginning of its use. Compared with the prototype, the treatment was faster and more effective due to the fact that rigid inserts after modeling exactly correspond to the individual bend of the human body in the lumbar region and abdominal press, due to the dense constant contact of the inner surface of the lumbar posture corrector with the user's skin according to the inverse principle connection activated reflex to maintain a physiological position. The presence of a rigid insert in the abdominal area prevents excessive flexion in the lower back and eliminates overload of the lumbar spine. The positive effect of rigid inserts is realized in a standing position, sitting, lying down, as well as during the performance of any physical work. The presence of a removable lumbar roller contributes to the formation of the necessary deflection of the lower back and the creation of support for the lower back in the sitting position, as well as in the supine position, including during sleep. Observation showed that the proposed design features of the lumbar corset-posture corrector allow you to maintain correct posture, prevent or reduce pain, discomfort and tension in the back, which leads to an increase in the effectiveness of analgesic action, more effective correction and maintenance of correct posture.

Thus, the use of a lumbar corset-posture corrector, allowed to achieve the stated result, namely to increase the effectiveness of treatment.
