Description

The invention relates to medical equipment, in particular to simulators stretching the interdisc spaces of the cervical spine. It can be used to straighten the spine in a sanatorium or other educational institution under the supervision of a medical professional.

Currently, these measures are performed by a medical worker, while the patient is lying, and the medical worker is jerking his head, or the patient is sitting, and the hands of the medical worker are covering the patient’s neck and also jerking the patient’s head up.

Known [1] is a dynamic simulator for straightening the spine, stretching the cervical vertebrae, training the leg muscles, which allows you to stretch the spinal column, which will allow it to straighten and improve posture.

The disadvantage of [1] is that it is not entirely convenient, since it is problematic to use it independently. Also for its use it is necessary to fix the neck, both arms and legs. When performing stretching, a person assumes a “butterfly” pose, which not everyone can do. The claimed simulator cannot stretch the spine in length.

Known [2] sports simulator, which allows you to stretch the spine in length, which improves posture and peripheral nervous system.

The disadvantage [2] is that it is very voluminous and requires the help of a second person, since it is necessary to fix the neck of the legs and arms. Also, it does not take into account the individual structural features of the human spine.

The closest to the merits of the claimed invention, the prototype is a simulator [3]. The patient is in a sitting position on an inclined bench, resting his feet on a special support, trying to make an inclination forward helping himself with a special bar. The patient holding his hands on the bar in the tilt position reaches for it with outstretched hands. As the spinal column stretches, the bar is fixed in an even farther position from the pelvis.

The disadvantage of the prototype [3] is that the stretching of the spinal column does not occur evenly, but depends on the location of the strap. The strap is fixed in special grooves with a step of 10 cm. Also, the absence of vibrational movements in two planes reduces the degree of stretching of the spinal column.

The aim of the proposed invention is the ability of the patient to independently perform the procedure of straightening the spinal column of the cervical spine.

The goals are achieved by the fact that the cervical spine stretching simulator, consisting of pillow clamps, the main and auxiliary to cover the patient’s neck, as well as the load-bearing attachment, is additionally equipped with three sets of converting rotational motion into reciprocating, two of which carry out movement horizontal plane along mutually perpendicular axes, and the third carries out reciprocating movement of the clamps in the vertical axis, each of which in turn contains electric motor with a disk on the shaft. The crank is pivotally mounted on the disk to the provided rod, and to the other end, which is also pivotally mounted, the end of the link, moving in a fixed element, and the other end of the link, is fixed to the movable element of the said node, bearing the load, while the simulator is also additionally equipped with a speed controller electric motor, and said rod on the disk is fixed so that it is possible to adjust the distance to the axis of rotation of the disk, and said cushion clamps are movably fixed relative to each other, and also to the load bearing node.

The essence of the claimed invention is illustrated in FIG. 1, FIG. 2, where 1 is the simulator body; 2 - pillow clamps main; 3 - pillow auxiliary collars; 4 - hinged mounts; 5 - node bearing the load; 6 - electric motor; 7 - disks; 8 - stock; 9 - crank; 10 - backstage; 11 - fixed element; 12 - cross joints of the two parts of the wings 10.

The simulator stretching the cervical spine works as follows. The patient’s neck is in the space between the clamps, the main 2 and auxiliary 3, this is possible due to their articulation 4 between each other and to the node 5, bearing the load.

All three sets of conversion of rotational motion into reciprocating occurs due to the electric motor 6 and the disk 7 on the shaft of the electric motor 6, the rod 8 on the disk 7 and the crank 9, to which the fixed link 10, which reciprocates moves in the fixed element 11. Spatial the movement of the part of the backstage 10 is possible due to the connection of the two parts of the backstage with a cross-shaped connection 12. The movement of the clamps 2 in two horizontal mutually perpendicular directions of reciprocating and vertical th axis reciprocating motion, carried out by the presence of special runners in the corresponding node 5 in the axils load bearing vertical axis.

The patient, loading the clamps with his own weight, regulates the load on his interdiscal space of the spine, also performs a reciprocating movement in the horizontal plane back and forth, turning one of the electric motors left and right, as well as up and down. The patient adjusts the speed of movement with the control button of rotation of electric motors.

The range of motion is regulated by the simulator's maintenance personnel, and due to changes in the distance between the rod and the axis of rotation on the disks.

Using the simulator for stretching the cervical spine allows the patient to independently (after preliminary training) conduct a session of traction of the spinal column, both in the cervical and in the thoracic region. The patient himself doses the load on the spinal column, as well as the time of exposure to it. In case of pain and not pleasant sensations, the patient can independently terminate the session. The device is designed in such a way that the risk of injury is minimal. As a result of the session, the vibration effect has a massage effect on the back muscles, and stretching the spine can improve metabolism and improve the interaction of the central nervous system (CNS) with the neuromuscular system.

This device can be used by people with scleosis, lardosis or kefosis, and according to statistics this is 90% of the population.

The claimed technical solution can be implemented in medical institutions, sanatoriums, physical dispensaries and patient rehabilitation centers.
