The invention relates to medical technology, in particular to devices for massage through torsional vibrations of the muscles of the patient's limbs and can be used for training athletes and for therapeutic purposes.

The purpose of the invention is to increase the effectiveness of the massage by providing the patient with forced torsion torsion.

Fig, 1 shows a device, axonometric; in fig. 2 is a view A of FIG. ; in FIG. 3 is a view B in FIG. 2.

The device for vibration massage consists of a two shoulders lever 1, on each arm of which a weight 2 is installed with the possibility of adjustment from the two shoulders lever 1, handles. 3, electric motor A of the mechanism of oscillations in the eccentric 5, connecting rod 6, bar 7 and lever 8. Manual 3 is rigidly connected to the electric motor 4, two shoulders lever and eccentre pc 5 installed on the shaft 9 of the electric motor, and t ha 7 of the mechanism of torsional vibrations pivotally connected with the two-arm lever.

The device works as follows.

Before starting the massage, set the required frequency of torsional (brushing-penetrating brush) vibrations of the electric motor 4 and the handle 3 with the brush holding it around the longitudinal axis 0.0-2 of the shaft 9 relative to the double-arm lever 1 with weights 2, for this, squeezing the fingers of the handle 3 ; 4-dc electric motor is connected to the power source and the required number of revolutions of the shaft 9 is set by selecting the required voltage value. In this case, the eccentric 5 with the help of the connecting rod 6 would have to move the lever 8 on the JO rack, and together with the lever 8 in the same way, move the th 7, Therefore, torsional oscillations of the two shoulders 1 relative to the electric motor 4 and handle 3 with the brush holding it around the extension axis 0.02 should occur shaft 9 with a given frequency (for example with a frequency of 15 Hz). But in fact, in view of the fact that the moment of inertia 1 and the two shoulders of the lever 1 with weights 2 relative to the axis 0.0, shaft 9

12

2) considerably exceeds the moment of inertia of the electric motor 4 and the handle 3 with the brush holding it with respect to

the same axis, the two shoulders lever 1 with weights 2 almost remains motionless. The oscillatory movement with respect to this lever is made by the electric motor 4 and the handle

3 with a brush holding it. By moving weights 2 along the shoulders of the two shoulders lever 1 during specially performed short-term outages of the electric motor 4 from the power source, the required amplitude of rotation of the handle 3 with the brush holding it around the longitudinal axis O, 0 of the shaft 9 (for example, an amplitude of 10 °) is achieved. In FIG. 1, the turns of the handle 3 occurring during its torsional vibrations with respect to the two shoulders of the lever 1 are indicated by the arrows of the whig. Then the electric motor 4 is disconnected from the power source. At this point, the preparation of the device for the warm-up massage is completed.

Now, a person who, with the help of the proposed device, wants to have a massaging mechanical effect on the brush with torsional vibrations, it is enough to squeeze the handle 3 with the fingers of the brush and connect the electric motor 4 to the voltage source

for a period of time sufficient to obtain a session of effective massage of the hand (for example, for 2-3 minutes). For the massaging effect on the forearm and especially on the shoulder, it is necessary to increase the degree of compression of the fingers 3 with the fingers, and in the latter case, you should straighten the arm and tension the forearm and shoulder muscles. I

The counterweight 11 balances the action of the masses of the connecting rod 6, the lever 8, the pillars 10 and the ti 7, which tend to bring the axis of torsional vibrations of the handle 3 away from the axis,
