Description

The present invention relates to the field of technology for massaging the human body in order to provide resource support to the body, by relieving muscle spasms, swelling, improving blood circulation in tissues and metabolic processes in general.

The Russian Federation patent for utility model No. 70129 “DEVICE FOR PNEUMOMASSAGE” is known. A device for pneumomassage containing a housing in which the inlet and outlet channels with seats are made and a shut-off element with an electromagnetic drive of the shut-off element in the form of a magnetic circuit with a coil and a core is placed, in which the shut-off element is made in the form of a rocker arm, which alternately shuts off when the working pressure is supplied and released. environment, with one arm the saddle of the exhaust channel, with the other arm - the saddle of the inlet channel, while the rocker arm in its middle part is fixed to the magnetic circuit in such a way that the arms of the rocker arm, in the absence of pressure from the working medium and the electromagnetic drive is not turned on, do not overlap the saddles of the inlet and outlet channels, wherein the outlet channel is made in the core, and the body is equipped with an elastic shell, characterized in that at least one of the elements of the magnetic circuit is made of a hard magnetic material and is magnetized to enhance the attraction of the armature to the core made of magnetic conductive material and closing the seat of the inlet channel of the core in the absence of power supply to coil of the device, and the opening of the core channel is carried out by applying power to the core coil of such a polarity that will cause magnetization in the core in the same direction as the armatures at the point of their contact and will cause their mutual repulsion and the opening of the inlet channel of the core and the closure of the outlet channel of the device.

The disadvantages of the useful model described above are, firstly, that the vacuum effect is applied to a certain area, and with a decrease in the area of influence, its effectiveness decreases. On the contrary, to eliminate the so-called “trigger points” and effective relaxation of spasming muscles, a targeted mechanical effect is necessary. Secondly, the scope of application of vacuum exposure is limited by the anatomical features of the body, the presence and intensity of hair. Vacuum exposure is used mainly for the prevention and treatment of various diseases resulting from endothelial dysfunction, which results in microvascular disorders in the form of ischemia and venous stagnation of blood. The effectiveness of solving the described problems by using vacuum methods of influence is beyond competition.

The closest to the claimed invention is US Patent Application No. 20220133585, “MOTOR AND PISTON ASSEMBLY FOR IMPACT MASSAGE DEVICE.” The self-contained reciprocating mechanism is connected to the body of the percussive massage device and is configured to receive an applicator head to stimulate the user's muscles. The self-contained reciprocating mechanism includes spatial positioning bracket, semi-cylindrical bracket, piston, motor, crank and reciprocating linkage. The spatial positioning bracket is configured to receive other interconnected components of the self-contained reciprocating mechanism and position said components relative to each other within close specified tolerances to ensure that the interconnected components are correctly positioned to provide consistent performance characteristics.

The disadvantage of this solution is that the device is aimed only at performing one type of massage effect, namely, percussion movements. The result of only a shock effect on the human body is a tonic, not a relaxing effect.

The claimed invention is implemented in the form of a combined-action massage device that combines shock (percussion) and wave (kneading) mechanical effects on the human body.

The technical result of using the claimed device for impact-kneading action in contact with the human body is:

Percussion, neuromuscular effects on the skin, muscles, fascia, joints and ligaments using percussive movements.

Wave kneading effect on the skin, muscles, fascia, joints and ligaments using wave mechanical action.

The technical result is achieved due to the fact that the shock-kneading massage device consists of a body, a reciprocating motion generation unit, a rod, an attachment to the rod, a power source and an electric motor with a gearbox. The reciprocating motion generation unit contains an oscillation modulator, a lower rod guide bushing, a slider, a return spring, a rod and an upper guide bushing. The housing additionally contains an end cap, louvres for flow-through ventilation of the electric motor, a head part of the housing and a lock for the head part of the housing. The oscillation modulator is made in the form of a disk with a relief surface on one side. The device has an additional power source in the form of a battery.

DISCLOSURE OF INVENTION

The essence of the invention is illustrated by drawings:

In fig. 1 and 2 show a diagram of the design of a massage device with shock-kneading action.

Description of the technical part

The claimed massage device with shock-kneading action is implemented in the form of an oscillation generation unit and a power source connected to each other by an electric cable.

The shock-kneading massage device 1 consists of a body 2, a reciprocating motion generation unit 3, a rod 4, an attachment on the rod 5, a power source 6 and an electric motor with a gearbox 7. The reciprocating motion generation unit 3 contains an oscillation modulator 8, a lower rod guide bushing 9 of rod 4, slider 10, return spring 11, rod 4 and upper rod guide bushing 12. Housing 2 additionally contains an end cap 13, blinds for flow-through ventilation of the electric motor 14, head part 19 of housing 2 and retainer of head part 15 of housing 2 The oscillation modulator 8 is made in the form of a disk with a relief surface 16 on one side. The shock-kneading massage device 1 has an additional power source in the form of a battery 18.

The housing 2 of the device has blinds for flow-through ventilation of the electric motor 14. The electric motor with the gearbox 7 is installed inside the housing 2 and connected to each other by means of a rotating shaft of the electric motor 20. Torque is transmitted through the shaft of the electric motor 20 to the reduction gearbox. One of the variants of vibration modulator 8 included with the device is attached to the gearbox shaft 21. The oscillation modulator 8 is a disk with a relief surface 16 on one side. The modulator 8 rotates relative to the slider 10 connected to the rod 4. The axes of the bearings of the slider 10 move along the guides machined in the head part 19 of the device, performing reciprocating movements. Thus, the entire rod-runner assembly performs reciprocating movements. The surface relief of the vibration modulator 8 determines the amplitude-frequency characteristics of the movements of the rod-runner assembly and the type of impact on the human body. Different geometric characteristics of the grooves on the surface of the vibration modulator 8 provide different combinations of shock-kneading effects. The oscillation modulator 8 is fixed on the gearbox shaft 21 with a sleeve with internal thread. The modulator mounting sleeve 8 serves as the lower axial guide sleeve of the rod 9 for the rod-runner assembly. The upper guide sleeve of the rod 12 is fixed in the head part 19 of the device. Between the inner part of the head part 19 of the device and the body of the slider 10, a return spring 11 is installed on the axis of the rod 4, pressing the slider 10 to the relief part of the oscillation modulator 8. A nozzle 5 is attached to the outer part of the rod 4 for contact with the human body.

The part of the device body 2 opposite from the nozzle 5 is closed by an end cap 13. The plug 13 includes an electrical cable 17. The massage device is connected to a power source via an electrical cable 17. The massage device 1 can be equipped with a motor designed for different voltages. Device 1 has a PWM module for smoothly adjusting engine speed by changing the frequency characteristics of the current at a constant torque on the shaft of the electric motor 20, which can be located either inside the housing 2 or outside it.

The device may be able to use both a stationary power source from the network and power through an autonomous source, battery 18, located either inside the housing 2 of the device or outside it.

Objectives of the declared device

The shock-kneading device is intended for a hygienic massage effect on the human body and solves the problem of relieving muscle spasms and their individual bundles, releasing pinched nerves and nerve trunks, restoring normal blood flow through arteries and veins.

Relieving muscle spasm and joint blocks is especially important in the spine area. Joint blocks arise due to a tone-strength imbalance in the muscles surrounding the joint. In this case, some muscles (shortening) bring their attachment points closer together, while others (stretching) remove them. The relative position of the articular planes of adjacent joints changes, which leads to disruption of their mutual gliding and limitation of angular movement. The endorhythm of the spinal motion segment is disrupted. The muscle associated with this vertebra becomes functionally weak.

The work of the shock-kneading massage device is aimed at completely restoring the mobility of articular joints, the movement of which is limited due to displacement in the joint, spasmed muscles, the formation of articular blocks, primarily in the spine, returning articular joints to the physiologically correct position with restoration - correct biomechanics of the body, correct position of the spine, circulation of blood, lymph, interstitial fluid, general improvement of the body due to the normalization of the processes described above.

As already mentioned, the use of shock alone tones the muscles. Using only a kneading effect relaxes the muscles that are in good shape, however, in the case of muscle spasm, it is ineffective.

A shock-kneading massage device combines the best of two effective methods for relieving muscle spasms, described below:

1. Ischemic compression method. Ischemic compression is a method of short-term static compression of a muscle in order to limit blood flow and, as a result, access to oxygen to the muscle. Under conditions of oxygen starvation, the muscle cannot be in a state of tension (spasm) and relaxes. When ischemic compression is performed correctly, relaxation occurs within 1-2 minutes. The advantage of the method is speed and efficiency. The disadvantages of the method include the painfulness of the effect for the patient, sometimes the inconvenience of use due to the anatomical features of the impact site, and the need for good physical preparation for the performer, since the use of the method is physically expensive.

2. Postisometric muscle relaxation, i.e. muscle relaxation after exercise. The advantage of the method is efficiency. The disadvantages include the inability to perform with any person, for example, a child, because

- firstly, the patient’s involvement in the process and an accurate understanding on his part of what needs to be done and how is required;

- secondly, when trying to tense the desired muscle, further compression of the nerve or joint may occur, which is very painful for the patient.
To solve the problem of relaxing a muscle or muscle group, several sessions are usually required. In some cases up to 10 or more.

The claimed massage device with shock-kneading action forms a complex amplitude-frequency characteristic of the reciprocating movements of the shaft with an attachment that acts on the desired area by adding a pulse + wave effect or / sinusoid + meander or / percussion + kneading. Such an impact, carried out with a high frequency, inaccessible with conventional manual massage, on the one hand, causes a short-term deterioration in blood supply to the muscle + intense fatigue, which leads to effective relief of spasm.

Operational benefits:

- the result in the form of spasm relief or elimination of the trigger zone is obtained quickly, in just 1-2 minutes;

- the effect on the body is quite comfortable for the patient;

- hardware impact is not physically expensive for the performer.

Technical advantages:

The proposed shock-kneading massage device has the following technical advantages:

* Internal fastenings of the electric motor and gearbox, and therefore there are no elements for their fixation on the outer part of the housing.

* The design provides for cross-ventilation of the engine. There are ventilation louvers at both the top and bottom of the engine location.

* Changing engine speed does not occur by adjusting the voltage in the power source, but by changing the frequency characteristics of the current, by using a special PWM module. Due to the use of this structural element, a change in the speed of the electric motor occurs without a drop in torque on its shaft.

* The oscillation modulator is a disk with a relief surface, on one side, fixed to the gearbox shaft. The design of the device assumes the possibility of only axial movements of the rod-runner block. The modulator washer rotates, while the supporting elements of the runner move along the grooves of the modulator. So the rotation of the modulator washer is converted into reciprocating movements of the shaft.

* The design of the device has the necessary set of insulating elements to protect people from electric shock.

* All main elements of the device are located on the same axis.

* Reciprocating motion of the shaft is realized without the use of a crank mechanism.
