Description

 The invention relates to medical equipment, namely to physiotherapeutic devices for vertical traction of the spine, used in the treatment of lumbosacral radiculitis, sciatic nerve neuritis, in the treatment of vertebral osteochondrosis, for the correction of compression of vertebral bodies and other pathological conditions in which traction of the spine is indicated, as well as to reduce the longitudinal loads on the spine when lifting weights by a person.

 A device (1) is known for unloading the spine, containing pelvic and axillary supports, chest belts and spacer units made in the form of telescopic rods pushed apart by the action of compressed twisted springs, equipped with devices that regulate their spacer force and located on the left and right sides of the device so that the upper end they abut against the axillary supports and chest belts, and the lower end through the sliding racks are pivotally connected to the pelvic support with the possibility of combining their axis of rotation with the axis of rotation I have hip joints so that the patient himself can carry out this combination.

 The disadvantage of this device is excessive complexity, which leads to a complication of the technological process of its manufacture and to increased cost, as well as the lack of the possibility of mechanical adaptation of the device during movements of the shoulder girdle. So: (1) the use of sliding racks that articulate the telescopic rods with the pelvic supports is unnecessary, (2) the rigid connection of the telescopic rods to the axillary supports is undesirable, (3) the use of compression springs in the telescopic rods leads to a spring, which has a tendency to transverse curvature to its main axis during compression, abuts against the walls of the telescopic rod, and this friction leads to the appearance of an uneven (spasmodic) spacer force when the rod length changes. In a tensile spring, such transverse curvature does not occur.

 The purpose of the proposed device for the rehabilitation of the spine is to simplify the design of the nodes and improve the functioning of the device while maintaining all the positive properties of the prototype.

 This goal is achieved by the fact that in the telescopic rods are located tensile elastic elements, such as springs, while each elastic element is connected from below to that part of the telescopic rod, which is connected with its upper end to a hinge mounted on an axillary support, and the second end is an elastic element connected to the upper end of that part of the telescopic rod, which is connected by its lower end through a flexible connection, for example, a cable, to the pelvic support. The device for the rehabilitation of the spine is also additionally equipped with a length regulator for the telescopic rod located on one of its parts, and a tensile regulator for the elastic element located between one of the parts of the telescopic rod and the elastic element.

 It should be noted that according to the condition of the prototype of the invention, it is desirable that the applied elastic body has a deformation characteristic approaching the linear Hooke law.

 In all the scientific and practical literature available to the applicant, devices of a similar purpose and with a similar set of features are unknown. Therefore, the claimed device meets the criterion of "novelty", and since all the signs indicated in the claims are necessary and sufficient to achieve the goal, the claimed device meets the criteria of the invention of "significant novelty."

 The invention is illustrated in the drawing, where figure 1 shows a device for unloading the spine, a General view and placement of it on a person. Figure 2 shows a telescopic rod, expandable due to tensile forces of tension of a spring or other elastic body.

 The device for the rehabilitation of the spine, shown in figure 1, contains two spacer units 1 made in the form of extendable telescopic rods under the action of tensile forces of a deformed body, such as a spring, the internal force of which is regulated by the device 2. Telescopic rods are located on the left and right sides of the device ( figure 1 shows one such rod, and the second, hidden by the human body, is placed along its left side) so that the upper end of the rod rests on the axillary supports 3 with which they are connected Res hinge 4, and the pectoral axillary belt support 5 is held from sliding out under their hands. The lower end of these rods are supported through a flexible joint 6 in the form of a cable or cords from an eye 7 on pelvic supports consisting of a belt 8 and loops 9. The length of the flexible joint 6 is selected so that the points of attachment to the telescopic rods in the eye 7 coincide with the axis of rotation 10 hip joints.

 An example of a telescopic rod device is shown in FIG. The device consists of two parts, for example, cylinders: the outer part 11 and the inner part 12 sliding inside it. To the outer part from the side of its open end in the transverse direction, a pin 13 is rigidly fixed, passing through the groove 14 of the inner part, not preventing the movement of the part 12 in the part 11 with a pin 13 attached to it. On the lower side of part 12, a cap 15 is fastened with an eye 7, for example, by means of a screw and a threaded hole 16, selectively through a hole (for simplicity, only three holes are shown in Figure 2B). Choosing a hole, you can attach the plug 15 to part 12 at different depths. Thus, the part 12 together with the plug 15 form a rod, the length of which can be selected. An elastic body 17, such as a spring having elastic tensile deformation, is located inside part 12. At one end, the spring is connected to the back side 18 of part 12, and at the other end, the spring is connected to pin 13. The amount of deformation of the elastic body depends on the length of the rod: the length of part 12 with the plug 15. By changing the length of this rod, you can adjust the force developed by the elastic body. This force can also be adjusted with a screw 19 with a nut 20 located on the rear side 18 of the cylinder 12. An elastic body 17 is firmly attached to the nut 20. By screwing the screw 19 in any way, for example, by stretching the screw through the hole 21 in the back of the part 11, the elastic body and also regulate the force developed by the barbell.

 The telescopic rod works as follows (see figure 2). The pre-stretched elastic body 17, due to its deformation, develops a force tending to bring the pin 13 fixed on part 11 closer to the back side of part 12. This leads to the development of a force aimed at extending part 12 from part 11, which creates between points 4 and 7 bursting force leading to sprain. The tearing force depends on the length of the rod formed by part 12 together with the plug 15, since the longer this rod with a fixed distance between points 4 and 7, the more the elastic body stretches. This force also depends on the stretching of the elastic body by means of a screw 19 and a nut 20.

 A device for the rehabilitation of the spine works as follows (see Fig. 1). The patient strengthens the belt 8, on which there is a loop 9, connected by a flexible connection 6 with telescopic rods 1. The patient belt strengthens on itself so as to create reliable support on the hips. Then the rods are rotated and axillary supports are placed under the armpits. After this, axillary supports are fixed with elastic shoulder mounts 3. If desired, chest belts may not be used, but when you raise your hands up, the conditions for fixing the device on the human body worsen. Next, you need to move the loop 9 along the belt 8 so that the axis of rotation of the articulated joints coincide with the axis of rotation of the hip joint. In practice, this is verified as follows: squatting on a chair and rotating into a vertical position should not create significant mechanical resistance to movement from the side of the device. The last stage of adjustment is to regulate the tensile strength using the device 2 and screw 19. The patient selects this force according to his feelings: too much force can cause poor blood circulation in the hands, leading to muscle pain and parasthesia, too little force will not give the necessary tensile effect the spine. On top of the device, the patient can, if desired, wear a shirt, sweater, jacket, coat, etc.

 With this device, the patient can walk around the apartment, on the street and in transport, can sit and get up, and lift certain weights, the lifting of which without this device could lead to a relapse of the disease. Therefore, to facilitate weight lifting and prevent the occurrence of back pain, a patient prone to the development of pain due to degenerative-dystrophic processes in the spine can prophylactically put on this device.
