The aim of the invention is a complex effect according to a given program on the patient’s tissue. The extremities of the vacuum and air overpressure synchronously with the pulses of change in blood pressure, heat rays (for example, light rays) expanding the capillaries by heating the tissues. , impulse currents (for example, dyadinae. mymic), which relieve vasospasm by giving: pathological signals of pain coming from the affected areas of the diseased limb to the cerebral cortex, on the nerve endings of the vasomotor centers (according to or cervical) - an electro-magnetic field of ultra high frequency current (UHF) and oxygenation of the patient's body.

This is achieved by the fact that the device is equipped with a thermal energy source installed in the pressure chamber, temperature sensors, a pulse current generator and a UHF generator with electrode mn, block.m. of oxygen supply with a mask and a rheograph unit with a multichannel sound source connected to the block. .m of the program control, mounted on the console and made in the form of electric connected between a generator, normalized rectangular buttons, a step finder and switches, and the pressure chamber is made rotatable and equipped with Hermetic lyuko.m with a folding transparent cover and a removable lid with two sealing cuffs.

The drawing shows a schematic diagram of the proposed device.

It contains a pressure chamber /, a pneumatic system 2 with a source of 3 vacuum and a source of overpressure air-x, a little 1 membrane-operated switching valves 5 and 6, an oxygen source 7 with a valve. Shutoff and electromagnetic drive 8, oxygen mask 9 and remote control 10.

The pressure gauge / tube is a germetological vessel with removable lids 11 and sealing cuffs 12.

In the upper part of the pressure chamber, the hermetic pass-through connectors 13 and 14 are placed; the hermetic hatch 15 contains the 1st support

the housing 16, a hinged lid 17 with a viewing window 18 made of transparent material (Plexiglas). The tightness between the support body 16 and the hinged lid 17 is achieved by an extra-tight gasket 19 pressed into the groove selected along the perimeter of the end face of the support body 16.

The hinged lid 17 is connected to the support body 16 by the loops 20 and pressed against it by means of latches and latches 21. In the pressure chamber / paenoMeipiHo case, hermetic lamps 22 are mounted on its surface, which allows for even heating a limb placed in a pressure chamber and excludes local overheating of the limb. In its lower part, along the longitudinal axis, there are two guides 24 along which the disputable trolley 25 moves with a mesh pad 26 on which the patient's limb is laid. Inside the pressure chamber / placed electrical temperature sensors 27, the electrodes 28 of the pulse currents connected to the corresponding blocks of the remote control 10 by means of electrical cables and hermetic pass-through connectors 13 and M.

The pressure chamber / is connected to the hydraulic lift device 29 by means of a rotary sector mechanism 30, which allows the angle of inclination of the pressure chamber to change to a horizontal plane and rotate around a vertical axis.

The control panel 10 contains an electronic unit 31 with a limb blood filling sensor 32, a software control unit 33, an automatic electronic temperature controller unit 34, a pulse current generator 35, an ultrahigh frequency current generator 36 with electromagnetic energy of an ultrahigh frequency current emitter 37, control of oxygen supply, reogograph unit 39 with a multichannel reogograph 40 and measuring electrodes 4 and a recorder 42.

Block 53 (The software includes a generator of normalized rectangular pulses 43 with a control button 44, a step finder 45, impact switches 46-50, switch-on switches 51-55 on and on, and exposure duration switches 56-60.

The automatic electronic temperature controller unit 34 contains an electronic measuring self-feeding and regulating device 61 with a target, limb temperature, and an automatic electronic temperature controller 62.

Structurally, the control panel 10 represents a rack having a welded frame, with compartments.x of which are inserted plug-in units.

The described device operates as follows.

With the help of a hydraulic lift, the devices 29 and the rotary sector mechanism 30 impart the required spatial position to the pressure chamber.

A sick endiHOTTb is placed in the pressure chamber in such a way that it is located on the net plow: ca: t, ke 26 of the support trolley 25. The airtight hatch 15 is opened and, using rubber cuffs, temperature sensors 27, electrodes 28 of the pulse currents are attached to the sore limb. and the measuring electrodes 4 of the multichannel reductraph 40. They include a multichannel reograph 40 and a recorder 42 and record the reograms of the diseased limb.

After analyzing the recorded rheograms and 5 laboratory test results (blood, M04.ii, capillary scans, etc.), the attending physician draws up the patient treatment program.

Blood pressure sensor 32 is fixed on the finger of a healthy limb, electrodes 37 of electromagnetic energy of ultra-high frequency are fixed by means of a belt, and oxygen mask 9 is attached to the face of the patient. effects 46-50, switches 51-55, the order of switching on switches 56-60, the duration of exposure, and the labier program control unit 33, the treatment program.

The temperature setting device of the electronic measuring, recording and regulating device 61 sets the temperature of the limb, which is automatically maintained by the automatic electronic temperature controller 62.

Potentiometers 63 and 64 of the generator 55 pulsed currents and the generator 36 currents of ultra-high frequency set the required values of these currents.

Include pneumatic system 2, and re. the oscillating organs establish the necessary vacuum and pressure in the sources 5, 4 of vacuum and air overpressure.

Using the oxygen reducer 65, set the required oxygen pressure upstream of the shut-off valve 8.

Button 44 of the program control unit 55 turns on a generator of 43 normalized rectangular pulses. The rectangular pulses from the generator 43 arrive at the coil of the stepper finder 45. The moving contacts of the latter, with an interval equal to the duration of the pulse period of the generator 43, move ino lamellas, turn on and off the electronic unit 31, the oxygen supply control unit 55, the generator 36 ultra high frequency currents, block 34 of the automatic electronic temperature regulator, g pulse current generator 55.

Inclusion of these blocks corresponds to the beginning of the physiotherapeutic effect, and disconnection means the cessation of exposure.

When the electronic unit 31 is turned on, the signal from the blood filling sensor 52 is subsequently fed to the input of this α-unit, where

the control signals are amplified and formed, and on the electromagnetic actuators of the low-inertia membrane switching valves 5 and 5.

Under the action of these signals, the latter alternately, opening and closing, connect the pressure chamber / source 3 with vacuum and source 4 of the air overpressure of the pneumatic system 2, as a result of which pressure and vacuum pulses are generated synchronously with the blood pulsations .

When the oxygen supply unit 38 is turned on, the electromagnet of the shut-off valve 8 is activated, the latter opens and connects the source of oxygen 7 to the oxygen mask 9, with the result that oxygen enters the latter.

When turning on the generator 35 pulsed currents, the current pulses through the cable and the hermetic inlet connector 14 arrive at the electrodes 28 of the pulsed currents. A pulsed current flows through the body region enclosed between the electrodes 28.

When the ultra high frequency generator 36 is turned on, the ultra high frequency current is supplied to the electromagnetic emitters 37 of the electromagnetic energy of the UHF currents.

When the automatic electronic temperature controller 34 is turned on, the signal from the electric temperature sensor 27 mounted on the sore limb through the hermetic inlet connector 13 enters the input of the electronic measuring, self-feeding and regulating device 61. From the output of the latter, the signal is proportional to the difference set by the temperature setting device and temperature of the diseased limb, is fed to an automatic electronic temperature controller 62, which changes the heating current of electric lamps nor, by which the temperature of the diseased limb is set equal to a given value.

For the simultaneous treatment of two limbs, a removable cap 11c is inserted into the pressure chamber / s with two sealing lips 12.

In this case, the device works similarly to its operation in the treatment of one limb.
