A device for vacuum compression massage (RU 2088195, 1997, including applicators placed on the surface of the patient’s body and communicated through a dispenser with a compressor-vacuum unit) is known. The device allows you to create a wave mode of rarefaction in the applicators with the creation of a vacuum in the cavity of each of them and excess pressure.However, such an embodiment of the device does not allow to achieve the required vacuum, especially with elastic or rough skin, as well as the need for the movement of the applicators on the surface of the skin leads to its additional injury.

A device for pneumatic vacuum massage (UA 65722, 2004) is also known, which contains a reduced pressure source, a pneumatic distributor with controlled valves, an electronic programmable control unit and an applicator in the form of a cuff with elastic sections. The device allows you to create several modes of pulsed exposure with different time and amplitude parameters, however, it does not provide the ability to control the rate of rise and fall of the vacuum.

Known portable vacuum massager described in RU 2187294, 2002 and considered as a prototype, containing a vacuum pump connected by vacuum hoses through an actuator unit to a manifold connected by appropriate flexible vacuum hoses with applicators, and an electronic control unit for exposure parameters associated with the control panel made with the possibility of setting the amplitude and time parameters of the exposure, an indication unit, a vacuum pump and an actuator unit. The device is intended for the formation of pulsed exposure to the skin in a wide range. However, it does not provide a system to ensure patient safety in the event of an accident in the power supply system.

The claimed invention is aimed at eliminating these disadvantages. The technical result achieved in this case is to expand the functionality of the device for vacuum massage with high repeatability of the specified rarefaction parameters, regardless of the characteristics of the skin and tissue of the patient, as well as increasing patient safety in case of malfunction of the device.

The technical result is ensured by the fact that in a vacuum massage device comprising a vacuum pump connected by vacuum hoses through an actuator unit to a manifold connected by corresponding flexible vacuum hoses with applicators, and an electronic impact parameter control unit associated with a control panel configured to set amplitude and time parameters of exposure, display unit, vacuum pump and actuator unit, optionally control unit exposure parameters associated with the control and shutdown unit, the first output of which is connected to a vacuum pump, and the second - with the block of actuators, additionally including pressure sensors and pressure regulators of change in vacuum, installed in the collector, the impact parameter control unit is configured to be formed in applicators pulse rarefaction mode with a constant frequency and a given rise and fall of rarefaction in time or a combined rarefaction mode superimposed on it pulse rarefaction mode with a constant frequency of additional rarefaction oscillations with a frequency selected in the range of 1.1-100 Hz, and / or wave rarefaction mode with successive creation of rarefaction in the cavities of the applicators.

In addition, a receiver is preferably mounted between the vacuum pump and the actuator unit.

Also, the collector can be equipped with a fitting for connecting the block of actuators

It is preferable that the control panel includes a procedure time switch, a minimum vacuum switch / a maximum vacuum switch, a pressure switch from a minimum to a maximum switch, a switch from a maximum to a minimum switch speed, a maximum pressure switch, a minimum switch, a switch, and a switch mode, frequency adjuster for additional rarefaction oscillations.

Regulators of the rate of change of rarefaction can be made in the form of valves with an adjustable flow area.

In addition, the applicators are equipped with air taps, and the control and shutdown unit is equipped with an audible warning device.

Figure 1 shows a functional diagram of the device, figure 2 - control panel.

The vacuum massage device (Fig. 1) contains a vacuum pump 1 connected by vacuum hoses through an actuator unit 4 to a manifold 7 connected by corresponding flexible vacuum hoses with applicators 8, and an electronic impact parameter control unit 3 connected to the control panel 24, the unit indication 5, vacuum pump 1 and actuator unit 4. Moreover, the impact parameter control unit 3 is also connected to the control and shutdown unit 6, the first output of which is connected to the vacuum pump m 1, and the second with a block of actuators 4.

As applicators 8, for example, the well-known applicator disclosed in SU 1571816 or RU 2166923 for performing a vacuum action can be used, which is a convex hemisphere made of a transparent material (plexiglass), having on its flat part a soft silicone elastomeric contact with the patient’s body a membrane perforated with holes (concentrators) to provide oxygen exchange in tissues at the site of exposure. Each applicator is equipped with an air valve for independent manual switching on and off the vacuum supply on the required number of applicators.

A wide selection of applicators of various configurations and areas of contact with the patient’s body, as well as options for installing vacuum applicators on the patient’s body, provide ample opportunity to choose the area of influence.

The power supply unit 2 of the device provides uninterrupted power supply voltage of 220, 24 and 12 V through connector 9 of the vacuum pump 1, electronic control unit 3, actuator unit 4, display unit 5 and control and shutdown unit 6. The power supply unit is also equipped with a toggle switch 12 (on the panel control) to bring the device into a state of readiness for work and connector 11 for connecting voltage from a 220 V network or a converter from 12 or 24 V to 220 V.

The electronic control unit for the exposure parameters 3 generates three types of modes on the applicators 8: a pulsed rarefaction mode with a constant frequency and a predetermined rise and fall of a rarefaction in time or a combined rarefaction mode with an additional frequency of additional rarefaction oscillations with a frequency selected in the range 1.1-100 Hz, and / or the wave mode of rarefaction with the sequential creation of rarefaction in the cavities of the applicators. Block 3 programmatically sets the following parameters during operation of the device:

- minimum vacuum;

- maximum vacuum;

- the rate of change of rarefaction;

- temporary sites for minimum and maximum vacuum;

- total procedure time;

- task and indication of the pulse mode;

- task and indication of the wave mode;

- task and indication of the combined mode.

The block of actuators 4 includes pressure sensors and regulators of the rate of change of rarefaction (not shown) installed in the manifold 7, the latter being valves with an adjustable flow area and ensures the operation of the device according to a given control unit 3 program.

The display unit 5 provides an indication on the display screen of the set modes: minimum and maximum vacuum, the rate of change of the vacuum and the time of the sites, the procedure time.

Structurally, the display unit 5 is built into the control panel 24 (FIG. 2), on which the procedure time dial 14, the minimum vacuum regulator 15, the maximum negative pressure regulator 16, the negative pressure change speed adjuster from minimum to maximum 17, the negative pressure change speed adjuster from maximum to minimum 18, exposure time setter with maximum vacuum 19, exposure time setter with minimum vacuum 20, mode selection switch 22, frequency setter for additional rarefaction oscillations 23.

Block 6 control of executable modes and shutdowns provides control and safety of the device, i.e. when the program crashes or deviates from the parameters set by block 3, it automatically stops the operation of the device by turning off the operation of the vacuum pump of the 1st power failure of blocks 3, 4, while the audible alarm device (not shown) is simultaneously turned on.

A collector 7 with air taps (not shown) for connecting applicators 8 provides the connection to the device of up to 10 or more applicators in various combinations and the convenience of installing vacuum applicators on the patient's body. Air valves are designed for independent manual switching on and off the vacuum supply in the required number of applicators, the applicators 8 are connected by a vacuum hose to the collector 7. The collector 7 is connected to the block of actuators through the fitting 21.

In the case of using a vacuum pump 1, during operation of which ripples arise (diaphragm, piston type, etc.), a receiver (not shown) is installed between the vacuum pump 1 and block 4. The vacuum pump is connected through the nozzle 10.

The operation of the device is as follows.

The first regimen used in vacuum massage is "pulsed", characterized by the cyclical nature of the vacuum in time. The pulse diagram is characterized by an increase in the first stage of rarefaction in time, at this moment, under the applicators, the underlying tissues and blood vessels expand, the flow of blood and lymph increases, the blood is saturated with oxygen. At the second stage, the upper rarefaction site “N max” is formed with a duration of 2 to 7 s, in accordance with the recommendations of a specialist, i.e. a section of the diagram on which the set vacuum is not changed for a predetermined time and the vacuum and load are aligned on the body section under the applicator. The third stage realizes a decrease in rarefaction in time, at the moment of a decrease in rarefaction, the tissues take their normal form, at this time the blood enriched with oxygen leaves the tissues and blood vessels in its channel. The fourth stage of the pulse diagram characterizes the lower platform "N min" lasting from 2 to 7 s, depending on the recommendations of a specialist, i.e. interval of time during which depression is not changed. At the next impulse, the steps are repeated, the blood is again infused and saturated with oxygen. As a result of the cyclical repetition of the process of intensive blood inflow and outflow, blood circulation is stimulated, metabolism and skin respiration in the massaged area of the body are enhanced, lymphostasis phenomena are eliminated, muscle tone and elasticity are increased, which helps to optimize nerve conduction, relax deep muscles, venous drainage is normalized, creating venous drainage prerequisites for the restoration and normalization of physiological processes in the surface tissues, restoration of the balance of muscle tone and fu ktsy motor segment.

When working in pulsed mode, it is necessary to turn on the device with a switch 12, set the mode switch 22 to position “A”. On block 3 set the necessary parameters of the procedure. On the board of the display unit modes 5 display the preset modes. The required number of applicators 8 is connected to the collector 7 with the taps closed. The device is ready to go. After turning on the “START” button, the vacuum pump 1 is turned on, creating a vacuum in the applicators according to the program set by block 3.

In the event of failure of one of the mode setters or a program malfunction, block 6 automatically turns off the vacuum pump 1 and turns off the power to blocks 3, 4, the “System Failure” signal and an audible signal are turned on on the display of block 5. Feedback block 3 is connected with block 5.6. The collector is connected directly to block 4 for feeding into the applicators the vacuum specified by the program block 3.

To perform the pulse mode, the collector 7 is connected to the fitting 21- "A".

The wave mode differs from the pulse mode by supplying, according to the block 3 program, the rarefaction and recession signals in succession undulating to a group of applicators installed in the direction of blood flow. The wave mode is used when necessary to smoothly move the vacuum in a certain pattern by sequentially turning the vacuum on and off in several applicators installed on parts of the body in the direction of blood flow. When working, in particular, of two applicators working in series, the upper area of the rarefaction pulse of each subsequent applicator coincides in time with the lower area of the rarefaction pulse of the previous applicator for smooth movement of the massaged areas. The use of this mode allows you to enhance the therapeutic effect compared to manual massage.

To work in the wave mode, the vacuum hoses from the applicators are connected to the fittings 21- "A, B". The mode switch 22 is set to position "B". The relevant information appears on the mode display. The operation of blocks 3 and 4 switches to wave mode.

To form a combined mode, use the pulse mode as the main mode (Maximum vacuum of 500 - 700 mm Hg, minimum vacuum of 190 mm Hg, areas with minimum and maximum vacuum levels are set from 0 to 120 s, with pulse resolution - 10 s. The rate of rise and fall of the vacuum is regulated in the range from 7 kPa / s to 50 kPa / s).

All parameters selected from a possible range are set by adjusters 14-20, which in turn transmit the selected information to block 3 for execution.

Then, rarefaction oscillations are applied to the pulse mode with a frequency selected by medical personnel for the necessary therapeutic effect when exposed to a selected organ through biologically active points. The device allows you to select the desired frequency in the range from 0.1 to 100 Hz. The selected frequency is fixed by the manual adjuster 23, which in turn transmit the selected information to block 3 for execution.

The combined regimen is used when combined with reflexotherapy and electroacupuncture to activate or deactivate the work of organs that are affected by biological active points.

To work in combined mode, the vacuum hoses from the applicators are connected to the fitting 21- "B". The mode switch 22 is set to position "B". The relevant information appears on the mode display. The operation of blocks 3 and 4 switches to combined mode.

The vacuum pump 1 is connected with an electric cord to the socket 9 and a vacuum hose to the fitting 10. The socket 11 is connected to a voltage of 220 V or a converter from 12, 24 V to 220 V. To the nipples 21 (A, B, C) depending on of the selected mode, a manifold with stopcocks is connected with a vacuum hose to which applicators 8 recommended by a specialist are connected. By turning on the toggle switch 12 on the control panel, the device is put into a state of readiness for work. On the board of block 5, the indication of modes is turned on. The mode switch 22 is set to the position of the mode of choice: A (pulse), B (wave), C (combined). The frequency adjuster 23 of the additional rarefaction oscillations allows you to select the desired frequency in the combined mode, after which you can begin to work. When you turn on the "START" button 13, the device is turned on and a direct or countdown procedure begins. During the procedure, the vacuum pump is constantly working, the display of the mode display unit 5 shows the set and the operating modes of the device. Block 4 of the actuators operates according to the program specified by block 3. At the end of the procedure time, the “end of procedure” panel lights up and a sound signal is given.

The parameters of the vacuum, the rate of change of the vacuum, the site and the time of the procedure are set on the recommendation of doctors and can be adjusted during the procedure.

This device has high reliability and durability thanks to the control unit executable modes.

The user-friendly control and display panel offers a wide range of mode options.

The device diagram allows you to work from a 220 V network and in stand-alone (field) modes of 12 and 24 V from a voltage converter.

A remote collector with shut-off valves provides ease of use and installation of vacuum applicators, as well as, without interrupting the procedure, to adjust the number of working applicators or the place of exposure.
