Description

The useful model relates to medicine and medical technology, and more specifically to the means for therapeutic and mechanical effects on the paravertebral muscles.

A device for back massage is known, published on the site: http://zdorovoyetelo.ru/katalog-tovarov/massajeryi-i-miostimulyatoryi/ The product is well suited for independent use, because it has long handles. Such devices for back and neck massage activate blood circulation, relieve fatigue in the back, shoulder girdle and neck, and even improve immunity. The comfortable shape allows you to massage even hard-to-reach places. In oriental medicine, this type of back massage has been used for a thousand years. Despite such a long history, the products are still effective for preventive massage.

The disadvantage of this device for back massage is the low effectiveness of the impact on the back muscles and the low ability to eliminate the causes of discomfort.

It is also known a device for back massage, published on the website: http://www.drevmassru.tremas7z.bget.ru/, consisting of a base, rollers installed in it with the possibility of rotation around their axes and a handle rigidly fixed to the base. By acting on the paravertebral muscles, the massage device eliminates the very cause of the disease, and not its symptoms. The general tone of the body rises, over time, diseases that were the consequences of a sick spine go away.

The massage is performed in the supine position. In this position, you need to grasp the protruding handles with your hands and move your body, pulling yourself up on your hands and pushing your feet back and forth from the floor. As a result of such movements, the muscles of the back are influenced by rollers installed in the base of the massager. The point action of the rollers effectively massages the back.

The disadvantages of this massage device are its size and the lack of easy transportation. In addition, the selection of a massager for a person's height is required, as well as the need to apply sufficient effort to move your body with your hands along it.

The closest in design is a device for back massage under the patent for a useful model of the Russian Federation No. 157876 (publ. 20.12.2015).

The proposed utility model solves the problem of improving the consumer properties of the product, and also reduces its cost, which allows us to speak of a higher competitiveness of the product.

This design of the back massage device makes it easy to transport it, facilitates the process of its comfortable use. In contrast to the above analogue, in which the massage device stands in place, and the human body moves along its base with the hands, in the proposed device movement occurs due to the legs and the body rolls along with the device on a flat surface, which significantly reduces efforts and creates a more comfortable environment for back massage. In addition, it is possible to massage the back to the shoulder blades and behind the shoulder blades together with the cervical spine.

The disadvantage of this back massage device is that when massaging the cervical spine, considerable effort is required to lift the back with the legs in order to massage the neck. This creates additional tension in the muscles, which has a negative effect on a person. In addition, not all people have sufficient physical fitness, and when the body is in a horizontal position due to its geometry, the effectiveness of massage of the cervical spine is extremely low. In addition, this design does not allow effective action on the lumbar spine. Thus, the practice of using the device has shown that it is most suitable for massaging the straight back. Additional elements are required for cervical and lumbar massage.

To achieve this technical result, in a device for back massage, consisting of a base with holes under the axle, which are installed in these holes, and on the axle opposite to each other on both sides of the base, rollers are installed in the middle part, three on each side, on the extreme axes along one, and in the middle part of the base there are rollers of different diameters: the first, closer to the base on both sides of it, are of small diameter, then with a stepwise increase of the latter to a larger diameter, and the rest of a larger diameter, rocker arms are installed on both of the extreme axes with the possibility rotation around this axis, and at the ends of the rocker arms there are axes and rollers on them, and the rocker arms are made so that one of the axes installed in the rocker arms is above the other axes of the simulator.

Distinctive features of the proposed device for back massage is that rocker arms are installed on both of the extreme axes with the ability to rotate around this axis, and at the ends of the rocker arms there are axles and rollers on them, and the rocker arms are made so that one of the axes installed in the rocker arms, located above the other axes of the simulator.

The proposed device for back massage is shown in FIG. 1-3:

in fig. 1 - shows a general side view;

in fig. 2 - the same, top view;

in fig. 3 - the same, perspective view.

The device consists of a base 1, rollers 2, roller axles with roller clamps on axes 3, rocker arms 4, rocker rollers 5 and 6, rocker arms with roller clamps on axes 7 and 8. Base 1 is made of an aluminum square tube, roller axles with clamps 3, 7, 8 made of steel with an anti-corrosion coating, rocker arms 4 are made of aluminum, and all rollers 2, 5 and 6 are made of polyurethane, have bearings and are installed on axis 3 along the base 1 in three rows and on the axis of rocker arms 6 and 7. The order of installation of rollers 2 is shown in Figures 1-3. Along the edges of the base 1, one roller 2 is installed on each side of the axis 3, in the center, three on each side of the base 1 in the holes under the axis 3, made in the base 1. On the rocker arms 4, one roller 5 and 6 is installed on each side ...

The distance between the rollers 2 (Lm and L) is such that they do not have a direct effect on the spine, but interact only with the paravertebral muscles of the back. Thus, the possibility of damage to the vertebrae or other effects that can harm human health is excluded.

In addition, in the middle part of the base, rollers of different diameters are installed, the first ones, closer to the base on both sides of it of small diameter, then larger, and the rest of the largest diameter. The diameters of the rollers, installed three on each side, differ slightly from each other, but at the same time create a surface in the form of a parabola, thus distributing the load on the back muscles and acting symmetrically on both sides of the spine, stretching the back muscles to the sides of it. As a result of this arrangement of rollers of different diameters, two effects are produced on the back muscles: one is pressing into the body and rolling along the spine, without exerting a direct effect on it, the other is stretching to the sides of the spine due to the different diameters of the rollers when the latter roll back and forth. For comfortable use of the simulator when massaging the neck, the rollers 2 installed on the left (Fig. 2) have a distance between themselves (Lm) along the axis 3, which is less than the distance (L) between the remaining rollers 2.

The rollers 5 and 6 located on the rocker arms 4, which are interconnected by the axis 7 for their synchronous rotation around the axis 3 of the rocker arm 4, can freely rotate around the latter. This design allows you to act on a curved surface, copying it and evenly distributing the load between the extreme rollers 5 and 6 of the rocker arm 4.

Using the back massage device:

1. We place the device between the legs so that it is behind the back, and the rollers on the rocker 4, 5 and 6 with a smaller distance (Lm under the cervical spine) were not under us, but further away. After that, we sit down on the device, leaning on our hands, with a pelvis between the extreme rollers 5 and 6 on the rollers 2 located between them, under us.

2. Next, we gently lie down on the device with our backs so that the spine is located between the rollers, and the head rests on the rollers on the rocker. This will happen naturally.

3. When the correct position of the back on the device is accepted and the legs are bent at the knees, we make small amplitude movements of the body along the spine, pushing it with our legs back and forth.

4. Then the range of motion can be increased and a simultaneous massage of the entire back, cervical spine and head can be performed. Duration initially from 30 s to 1 min. Further on your own.

Massage of the cervical spine and pelvis will occur arbitrarily, since the head and pelvis, while moving, act on the extreme rollers that are higher than the others, as a result of which the rocker arm rotates around its axis and the roller on the other side rolls around the neck, pelvis, pressing to the latter and copying their shape. The pressing force of the rocker rollers is equal to the weight of the person's head and pelvis. This massage does not require additional efforts and the body is in a relaxed state.

5. After finishing all the exercises, we turn over from the device to the right side and lie down with our backs on the mat.

6. After the massage, lie down, relaxing for 5-10 minutes.
