Description

The invention relates to biomedical devices, in particular to stimulants, and can be used for research, prophylactic and therapeutic purposes.

A known method for influencing biological objects with the hands of an operator whose physical field includes infrared (IR) radiation of 8-14 microns, microwave (microwave) radiation in the range of 8-30 cm and an alternating electric field with a frequency of 10 Hz.

A stimulator is known comprising emitters of light and sound waves mounted on a movable support and connected to a power and control unit.

A stimulator is placed in front of the patient, the main frequency of the patient's electroencephalogram is determined and the corresponding radiation is applied to the rhythm of this frequency.

The stimulator provides an increase in the patient's working capacity, but does not allow automation of the dosing of radiation. In addition, the type of radiation and the shape of the emitters are not adequate to those used in the non-contact stimulation method.

The purpose of the invention is to increase the efficiency of stimulation by automated dosing of radiation.

This goal is achieved by the fact that in the stimulator containing an emitter mounted on a movable support, the control unit, n-emitters are located on the surface of the support, limited by the project VI

s

These hands are connected to the control unit.

As emitters, sources of alternating electric field, infrared radiation, microwave radiation and heat are usually used.

The support is preferably made of two parts, on each of which additional emitters are placed on a surface limited by the projection of the left and right hand.

The stimulator (Fig. 1), in which the electrodes - the hands are located symmetrically and mounted on a movable support, is made in the form of a cap with the possibility of its movement in height.

A cylindrical floor, a rod 2, is mounted on the bed 1, on which a control unit 3 and a cap 4 with emitting electrodes are mounted. On the side wall of the cap 4, an electrode contour is shown, indicating the direction and location of elementary emitters (indicated by dots) on the electrode — hands (fmg.2). In the frame 1, a power unit of the device is located. Flexible electric harness 5 connects the power supply unit to the control unit 3, on which the radiation mode controls are installed, for example

thermal and radiator caps 4 Fixing bushings with retaining clamps b allow cap 4 and block 3 to be mounted on rod 2 on the required

height. The electrode (Fig. 2) at the points indicated by points 7 has seats for elementary radiators connected to a radiation source or power supply by flexible cores 8.

A similar design allows, thanks to the closed volume of the cap 4 in combination with the thermal action, to increase the efficiency of infrared radiation. To do this, a hairdryer is placed in the housing under the casing.

5 - heating element with a micro-fan (not shown in the drawing). The required temperature of the heating element is set by the control unit 3. And the tubular type air ducts create in the areas close to the electrodes - hands, increased air exchange. The design of the electrode - the hand can be simplified and unified.

As elementary emitters

5, infrared light emitting diodes (LEDs) are used which are mounted on seats using plug connectors or screw base terminals. Due to their small dimensions, a group of LEDs can be placed in each charging point, and they are powered by a flexible electric harness. Depending on the required radiation intensity, the number of switched LEDs in the group of LEDs is different, but the current in the series power supply circuit is kept optimal and each of the currently emitting LEDs has the maximum return. (SIPL) of the infrared subband that significantly expands the effective infrared effect (up to 8-12 microns).

5 With the use of SIPL in the mode of interference mixing (interference mixers) from two SIPL the full range (up to 16 microns) of IR radiation is achieved. The use of visible LEDs makes it possible to use light therapeutic effect, and alternating on the electrode — the wrist of LEDs in the visible and YK ranges — increases the efficiency of complex stimulation.

5 In FIG. 3, the principle of IR and thermal stimulation is disclosed. Upon receipt of the start command to the command unit 9, the power unit 10 is turned on, and with it one of the start blocks corresponding to the inclusion of infrared radiation (11) or a thermal stimulator

(12, after which the stimulus levels are adjusted by the control switch 13 and the regulator 14. The control switch 13 is a group of controlled keys 15 (Fig. 4), which are turned on by the distributor 16 in accordance with the level of the reference signal. the reference signal is set by the command unit 9 depending on the exposure level set by the treatment course (treatment program). The LED groups 17 are connected to the power source through a current stabilizer 18. Each of the keys 15 switches the output w us grounding and thereby stepwise varies the intensity of the infrared radiation SID- groups, in this case the radiation modes are defined by four options: a) LED 7 (the keys 15 are disabled); b) 5 LEDs (lower key 15 is on); c) 3 LEDs (middle key 15 on); d) 1 LED (one upper key 15 is on). For smooth (precise) adjustment of the radiation level, the current stabilizer has a control input. The temperature regulator of the heat emitters (Fig. 5) includes heating elements 19, blown by the fan 20. The temperature mode is determined by the current stabilizer 21. As heating elements 19, spirals from constantan (manganin) can be used, as well as special electric lamps with reflectors in a flask providing in addition to light radiation in the lower part of the visible spectrum (long-wavelength boundary) and a short-wavelength part of the infrared range. The level of heating is precisely maintained within specified limits by signals from the command unit, at the control input of the stabilizer 21 connected to the power unit 22.

To determine the control regimes, to select a particular course of treatment, the accuracy of the distribution of the thermal fields of the emitters and the picture of the temperature relief on the patient's skin during therapeutic radiation exposure is established using a thermal imaging complex (thermal imager).

It (6) consists of a thermal imaging camera 23 and a color thermal imaging monitor 24, the Camera 23 is directed at the acting hand 25 (the electrode of the device or the hands of a masseur) and is focused on the surface of the hand. The signal of the temperature distribution on the surface of the hand converted in the chamber 23 is displayed on the screen of the monitor 24. Image 26 on the screen of the monitor 24 corresponds to the temperature relief of the surface of the hand (on the palm and phalanges of the fingers). Parts of the surface of the arm 25 with the same temperature are highlighted in the image 26 in one color, the lower the temperature, the closer the color to red, the higher to blue and blue. Similarly, surface temperature reliefs are removed on the patient's body under the stimulator electrode.

0 The stimulation mode, in which the maximum therapeutic (healing, calming, etc.) effect is provided, is recorded and entered into the program of the treatment course.

5 The most effective is the complex nature of stimulation, for example, by IR radiation and an EM field. When exposed to an EM field, the signals arrive from the generator to the electrodes (capacitor plates) from electrically conductive materials, for example, two metallized plates, and in the landing currents for emitters (Fig. 2), it is possible to install heat-light or infrared emitters (Fig. 7). Warm light or

5 IR emitters (LEDs, SIPLs) are powered by the start-up unit 27, and the leads of the electrodes 28 are connected to an EM-field generator 29. To expand the functionality of a stimulator with symmetrical electrodes, it is supplemented with electromechanical tripods p. vertically moving nodes (Fig. 8). In tripods 30, rods 31 with electrodes attached thereto move

5 along the bushings 32 using electric motors 33 with a gearbox. Controlled stepper motors can also be used. Now, with complex stimulation, treatment courses (programs) can contain data not only on specific stimulation modes, but also on the coordinates of the location of the electrodes (in height), while normalizing the time of one or another kind of exposure. In device with

5, control over the coordinates of the action most fully achieves the option of complex stimulation together with microwave exposure.

Considering the operation of EM and microwave stimulators (Fig. 10), we note the presence of similar functionally blocks with the help of which this or that level of therapeutic effect is established. For example, an EM stimulator (Fig. 9) consists of a generator 34,

5 attenuators (attenuators) 35.36. switches 37, radiating electrodes 28 (Fig. 7) with translucent mirrors 38 and optocouplers 39. The indicators 40 of the exposure modes are connected to the outputs of the attenuators 35. Attenuators 35 are controlled

blocks 41 with indicators 42 of the results of exposure to the output by means of signals from optocouplers 39 and a block 43 for communicating with the control unit. The generator 44 through the control units 45, the switches 37 and the attenuators 36, as well as the generator 46 maintain the radiation level at the electrodes 28 within a predetermined range. The microwave stimulator (Fig. U) is powered by block 47. The automation unit 48 maintains a constant level of radiation from the microwave generator 49 due to the feedback circuit (generator 49, power meter 50, and automation unit 48), through a control input which (block 48) also starts the microwave generator. Further, the signal through the waveguide 51 (coaxial cable) enters the emitting electrode 52 — a cylindrical dipole with a protective cap made of impact-resistant polystyrene (Fig. 11). The coaxial waveguide 53 is connected to the microwave generator by a connector 54.

Behind the radiating dipoles 55, a conical shaped screen 56 is placed, which prevents microwave radiation from entering the back of the electrode. Dipoles 55 are closed by a casing (cap) 57 protecting the patient from contact with the conductive elements of the electrode. The character of the flux from the microwave electrode with cylindrical dipoles is strictly concentric, with a maximum level of radiation in the center and a weak effect along its edges, which is confirmed by the results of thermal imaging measurements. When fastening on the inner surface of the casing 57 of a metal plate 58 (steel screen former), for example, from a foil 0.15-0.18 mm thick with holes with a diameter of 180-2CJ mm (section AA in Fig. 11), approximating the microwave stimulating flow in shape to the hand, the radiation is established uniform over the entire surface of the radiating electrode - the hand,

The use of an electrode in the form of a hand allows the multivariance of the therapeutic microwave effect in the centimeter range (from 2 to 10 GHz). The radiating electrode is constructed based on hollow waveguides and horn emitters. Matching microwave distributors (attenuators) in the indicated range, due to their small dimensions, fit freely into the volume of the radiating electrode - the hand (Fig. 2,12).

A monoblock microwave emitting electrode (Fig. 12) receives a signal that is adjustable in terms of radiation power from a compact

a semiconductor microwave generator through a waveguide made in the form of a branched waveguide distributor, with an individual horn installed at the output of each branch, one with the largest cross-sectional area for the palm, and the other five to indicate emitting finger zones. When determining the level of radiating exposure

0 of each of the horns in the area of the waveguide adjacent to the horn, a thyristor emitting power sensor can be integrated. To create a level of radiation - a sufficient therapeutic effect,

5, semiconductor microwave generators can be used in each horn emitter (FIG. 13). In this case, when drawing up a treatment program (course of stimulating effects), the regimen of each of the emitters is dosed individually for each patient. The relationship between the levels of radiation from each of the emitters and the corresponding results of stimulating effects are established using a thermal imager (Fig. E).

Changing the frequency of microwave exposure and setting its level in each of the emitters with precise control built-in

With a thermistor emitting power sensor, an individual most effective treatment course is prepared for each patient, since the thermal imaging monitor shows the exact distribution

5 temperatures (skin temperature) with a radiating effect. Thus, it is possible to completely repeat the temperature relief on the patient’s skin area when exposed to this area with a hand of a masseur-human, with an indication of the type of radiation, frequency and level of microwave exposure. The expansion of functionality during microwave exposure is also achieved due to the fact that the spectrum of microwave stimulation can be expanded in a constructive way. The generator for the palm of the electrode - the hand produces, as having large dimensions, the lower frequency of the emitting spectrum, and

0 generator for phalanges of the middle finger - a slightly higher frequency, with correspondingly reduced dimensions. The pattern is also observed for other microwave generators, and for

5 of the index finger and for the thumb with the little finger, waveguides with a distributor for two channels and only two microwave generators can be used. Pairs can be grouped and much simpler: the thumb is forefinger and the thumb is with the little finger. In this case, the waveguide distributors can be omitted, and the emitting horn must cover the phalanges of two adjacent fingers with its directional diagram (see Fig. 12). The radiation power level is controlled by blocks controlled from a command console connected to microwave generators by a flexible electric harness. Functionally, the operation of the complex stimulator (Fig. 14) is as follows. The command unit 59, receiving signals from the programmer 60, connects the power supply 61 to one of the starting blocks 62 or simultaneously to two. The trigger unit 63 for the vertical movement of the electrodes is started if a signal is received to execute the coordinate program, and then the blocks 64 for the vertical movement of the IR (65) and microwave (66) emitters, in accordance with the selected coordinates, set the electrodes at a height-determined level. The start blocks 62 are controlled by switches 67, with the help of which the level of PC- and microwave exposure is metered strictly according to the program, the inclusion of one or another group of emitters, or at the same time with a complex effect. The principle of switching PC and microwave semiconductor emitters is similar and fully disclosed in Fig. 4.

To implement the proposed technical solution for stimulation and non-contact massage in full, using automation and computer technology, a stimulation and therapeutic device based on an automated manipulator - a robotic stimulating complex - has been developed. From the functional diagram of the stimulator (Fig. 15), one can see the sequence of switching on of one or another effect depending on the treatment course (treatment program). The introduction of the treatment program and its subsequent reading is carried out by the command unit 68. The multichannel command generator 69 controls both the level and the nature of the action of various types of signals (light-thermal, infrared, microwave, etc.) associated with the operator through the command unit 68. The command unit 68 is the keyboard of a personal computer input device, and the multi-channel command generator 69 is its central processor connected via read-only memory controllers (ROM) 70 and 71 drives with ROM 72 and drive 73 on

magnetic tape or floppy disk on which control treatment programs are recorded. Shaper 69 is coupled to electrodes 74 made in the form of hands through trigger blocks 75.

The coordinate unit 76 included in the program, which is an actuator (manipulator),

0 moves the electrodes 74 in accordance with the coordinate data entered into the block 77 vertical and block 78 horizontal movements in accordance with the executed control medical

5 program. The level and type (kind) of exposure, the coordinate of one or another electrode - the manipulator’s hand, the time (interval) of the selected radiation (exposure), or the operation of the manipulator in

In the complex, they are digitally entered into a program recorded on a magnetic medium, for example, a flexible floppy disk, and are sequentially set by switchable blocks and groups of stimulating emitter stimulators. The thermal imager is also mounted on an automated manipulator, therefore, during the session, the effect itself is controlled by the temperature relief of the stimulated

0 (massaged) area. When exceeding a given level of stimulation, the limit. for a particular patient, changing the treatment course data, the patient’s desire, etc. medical stimulus qi

5 automatically stops. All blocks are controlled by touch (pseudo-touch) keys, which provides the necessary speed.

Control Units and Computing

0 funds are made on a modern elemental base, using standard microprocessor sets, eight- or sixteen-bit K-MDP series and MDP logic (K176, K561, etc.).

5 The proposed stimulator allows to increase the effectiveness of exposure by automating the dosage of radiation and to ensure the adequacy of non-contact exposure by placement

0 emitters on a support as part of fingerprints, supplying a control unit for regulating the intensity of emitters from different parts of the radiation surface and using a combination of sources of alternating electric field, PC radiation, microwave radiation and heat. The same contributes to the implementation of the support element of two parts, on each of which are placed within the prints of the right and left hands emitters. The stimulator can be made in the form of a robotic complex, including a mover kinematically connected to the support element and reading commands, for example, a programmable computer.

The stimulator can be used as an individual and collective

the driver of the controls introduced into the program is 5 means of psychological relief.
