Technical Problem This discovery solves the problem of constructing an apparatus for the application of vibration biomechanics. which by the use of a PC computer with the proper program and a therapy control unit. carries out the therapy on the basis of the given parameters obtained from the PC computer. whilst the computer simultaneously controls the therapy and obtains data about the patient. regarding the results of the treatments, and possible change in the treatments in accordance with the success of the treatments.

Current Technical Situation The medical properties of vibration are known and their use has been documented, an example of this can be traced back to medieval times where. through the use of vibrating chairs and alteration of the frequency, amplitude of vibrations and the duration of the treatment. according to the general state of the patient.

From non-patent literature devices called "Wave 1" and "Wave 2", which use the methods of vibration massage, are known. Through the use of these devices it has been proven that vibrations stimulate the diffusion processes characteristically associated with the reactions of the human organism. thus increasing the absorption power of the protoplasm. It is possible to create an increase or decrease in the activity of ferment, through the amplitude of the mechanical oscillation.

Furthermore, it is known, from non-patent literature, the use of vibration machines based on water massage for the healing of osteochondritis of the neck and the lower half of the back of the human body, the healing of the trauma of the peripheral nerve endings, polyarteritis. bronchial asthma, pneumonia. chronic gastritis, liver and gall channels along with other gynaecological and other illnesses.

From non-patent literature the construction of the "Vibroscanner", is known. This device was developed at the Institute of Machinovedenija at the Russian Academy of Science.

This device is used to stimulate the local skin zones on the human body.

From patent literature. in the field of relative innovation. from the YU declaration of patent p-204/86 by Max J. Rudeirian from Los Angeles, USA. a vibrating therapeutic apparatus for massage, is shown in several versions. This apparatus contains one or more heads which massage, and are powered by vibrating electro-motors, the eccentricity being on the shafts of these electro-motors. A propeller and an electric heater are contained on each of these shafts, for the purpose of heating the air which is blown to the place which the vibrating head stimulates.

In the YU patent list No. 31 774, whose owner is the "Metal Industry" Ozalj, "Therapeutic devices for vibrating and heating" are shown. These devices are contained in rubber, inside of which a vibrating apparatus consisting of an electro-magnet and a pin, and works on the principal of the electric bell. The purpose of the device is for massage of the human body, whilst heating the treated areas.

In the YU patent declaration P-437/89 by Milan Radakovic from Belgrade, the vibrating pillow used for the purpose of massaging various injured body parts, is shown. This pillow is made from sponge-like material, with built in electro-motor, whose eccentricity lies its shaft. and a small switch which works by touch.

On the basis of the above stated, the conclusion is that in all the above devices, except the "Vibroscanner" from the Russian Academy of Science, the vibration is directed at the injured or ill body parts or the human body as a whole. However, when the vibration is used on larger parts of the body, the organs and particular systems which are stimulated by the vibration. are not necessarily just the ones which are ill or injured. which benefit from such stimulation. but others on which vibrating stimulation has a negative effect. The deficiencies of devices which carry out vibrating stimulation are based on this particular conclusion, when a relatively large area of the body is stimulated.

The apparatus which is described in non-patent literature by the name of "Vibroscanner" of the Russian Academy of Science. carries out the vibrating stimulation of just the specific reflex areas on the human skin, which, when stimulated, bring about the desired therapeutic effect on various systems and parts of the organism. However, the deficiencies of this particular device come from its inadequate technological and technical level.

The basic concept of the invention On the basis of the above stated. the purpose of the inventions to create an apparatus to carry out vibration biomechanics. which by the use of a PC computer with the proper program and a therapy control unit. carries out the therapy on the basis of the given parameters obtained from the PC computer. whilst the computer simultaneously controls the therapy and obtains data about the patient. regarding the results of the treatments, and possible change in the treatments in accordance with the healing progress.

The apparatus itself is based on the principals of biomechanics. This solution enables a choice of vibration frequencies, in a wide range, from 16 to 120 Hz. each of which is optimal for a particular illness or disease of the patient. The apparatus is connected to a standard PC computer which carries out the control functions, such as the flow of the treatment and possibility of changing the treatment.

The apparatus is made up of a PC computer, which is essential, 8-bit vibroaplikator card for the PC computer which is compatible to today's types of PC computer, with training units(which are not protected by this patent) and working and vibrating units, and a program which enables and follows the therapy, and collects data about the patient and stores it on disk.

The PC computer is a standard device of a wide use, organised on modular basis and easily adaptable to a wide range of tasks.

The 8-bit vibroaplikator card is a specifically developed module, which carries out the control of also the working of the vibrating and training units. It contains a microprocessor which also controls the work of the vibrating and training units, along with sending information to the PC computer regarding the status of the system, the frequency and length of the treatment. This module is placed directlv in the PC computer bv simDlv connecting it to

the 8-bit BUS of the PC computer. The work of this module is controlled by a specifically designed program which is activated through the PC computer. The microprocessor which is built into this module is the standard Siemens microcontroller 80C537. All the vibrators, vibrating units and the motor of the training unit are under the control of this microprocessor.

Through the 8-BUS the microprocessor obtains the relevant information about the working frequency which is need on the vibrating units, the speed of the simulated walk, and the speed needed to be achieved by the training unit. Through this 8-BUS the microprocessor also receives from the PC computer the commands regarding the start and end of the work carried out by the vibrating units, training units, or the stopping of work of the whole system. Also contained in this module is the generator of the sound of walking. The control of the sound of walking is also carried out by this microprocessor. The module also has a connecting switch for the vibrating and training units.

The vibrating and training unit is the working part of this system. It is made up of an anatomically shaped chair in which the patient sits during the treatment. The most important part of the chair are the anatomically designed shoes placed on the training unit. The shoes contain four vibrators each, placed to cover the support zones of the sole of the feet. These zones are those on which it is possible to simulate walking, through vibration. The shoes are movable. so the patient is able to move their feet. in order to train and strengthen legs and feet.

In case the patient is unable to move their feet, the training unit has a built in motor, under the control of the PC computer, and this motor moves the feet of the patient in accordance with the treatment thus carrying out further therapy on the patient.

The computer programme developed for this apparatus, according to the invention, allows control and carrying out of the treatment, along with the supplying and recording relevant data regarding the patient and the state of the patient. The programme is organised in two parts. which are shown on the screen of the PC computer, as two separate windows. The first window(on the left hand side) contains information about the patient. Here the person carrying out the treatment writes in the name of the patient, the patient's illness or disease, the current state of the patient(pulse. temperature. blood pressure, ailments etc.). This information is permanently stored, and are able to be printed out at any moment as additional documentation regarding the illness of the patient. The second window(on the left hand side) contains the relevant parameters for the therapy of the patient, these include: frequency of vibration. speed of walk, length of treatment and the option of the training unit(depending on the mobility of the patient. These parameters can be altered using the keyboard, by entering the relevant numbers and by moving through the menus using the keys "LEFT, RIGHT, UP, DOWN" and "ENTER".

The parameter FREQUENCY is entered numerically, and in the range of 32 to 120 Hz.

This is the frequency with which the vibrators will work.

The parameter SPEED OF MOVEMENT is entered numerically, and in the range of 10 to 100 steps per minute, and it represents the imagined speed of walk of the patient, which is to be simulated.

The parameter LENGTH OF TREATMENT is entered by keyboard and represents the time limit of a particular treatment. The treatment lasts between 1 and 3 minutes.

The parameter WORK OF THE TRAINING UNIT shows whether or not the patient is able to move their feet on their own, or if the training unit is need for feet movement. If the patient is not able to follow the speed of walk simulated, the motor of the training unit is switched on to help the patient.

The treatment is started through the PC computer and the keyboard, and the relevant commands. The treatment ends automatically when the time set elapses. and this is when a

report regarding the treatment is given. The treatment is also able to be stopped prematurely by pressing the ESC key on the keyboard.

Then programme is organised on the principal of falling menus, and is very comfortable for use after a short training period. The programme allows for the use of a mouse, a standard part of any modern PC computer.

Through the above described way, the suggested apparatus for carrying out vibration biomechanics, according to the invention, represents a new solution to the set problem, and has an innovative level, which is completely acceptable.

The driver unit 26 is built in towards the base 2. whilst the lid 1 along with the side plate 3 and the screw-held 12 speaker 11 are built away from the base 2. Transformer 7 is fastened by screw 8 and plate 9 towards the bottom part of the base 2, whilst on the front plate 4, fastened by screws 27, three-switches 24 are placed, also a fuse 25 and three LED diodes 21 as well as a connection 22 held by screws 23. At the same time. on the back plate 5, a nest of connectors 13 is held by screws 14 as well as a nests of connectors 15 and 16 held by screws 17.

The microprocessor plate of the vibroaplikator card of the programming unit, on pictures 4 and 5, which is on the printed board 6 encompasses. through mutually corresponding electric connections, a connected microcontroller U 101 8751 -PLCC, a programmable circuit of U9 LATTICE connect by connector K3 DB25M. as well as two timer circuits U4 NE 555 and U5 NE 555 connected to the working circuits of the vibrators III and III' with transistors Q1 to Q16 as well as sources of power +5, +15, -15 and +50V and to connectors K1, K2 and K101.

The microprocessor plate on the printed board 6 functions through the programming unit II which is connected by connector K3 DB25M to the PC computer I, which generates signals need for work. These signals: Do-D7 as digital signals are signals used for the management of each single vibrator III.III' on both the left and the right shoe IV,IV'.

/CTP-signals of the rhythm of vibration. Through these signals vibrations of vibrators III, 111' are able to be carried out, chosen through signals Do-D7, /INTI-signals which represent the new beginning of work of the apparatus, and SELECT- signals calling on the apparatus for work.

Signals Do-D7, in the programmable circuit U9PLD1016, are transformed into the shape which is convenient for inducement of the working circuits of the vibrators III and III'.

The circuits consist of operational amplifiers U2A to U2C LM324 and U3A to U3C LM324 teamed up with four resistors each R1 to R24 thereby being configured as differential amplifiers for strengthening the voltage of the signal. The strengthening of the current is achieved through the exiting complementary transistors Q 1 to Q16 Bd 441 and Bd 442 with connecting bases and emitters, of which the emitting connection points are Y11 to Y24, for moving vibrators III,III'. At the same time, signals QO,/QO to Q7/Q7 for the inducement of the working cart of the vibrators III,III' are given by the programmable circuit U9 PLD 1016(LATTICE).

The exiting signals Y11 to Y24 for the movement of the vibrators III,III' are divided into two groups, left and right, and go to two separate connectors(Kl -left and K2-right).

The logical combination of signals/INTI and SELECT from the PC computer enables the work of the programming unit II. Through the circuit U5NE555 which is configured as an independent multivibrator. the work of the apparatus is enabled. only if connected to the PC computer I. In the case of the signal SELECT/INTI being left out of the exiting circuit U5NE555 it is not possible to turn on any of the vibrators III,III'. The circuit U4NE555 is configured as an oscillator which gives the carrying frequency of sound(signal OSC) which is created in the speaker 11. The programmable circuit U9PLD1016(LATTICE) controls the getting of sound through activating the signal SOUND at the corresponding moment. This signal further amplifies the electronic construction made up of resistors R31 and R32 and transistor Q17. The speaker 11 is connected to connector K4 and the sound switch is connected to connector K5.

The microcontroller U101 8751-PLCC for the control of work of the step motor with the entered programme, and is connected through connectors K3 as well as S1, S2 and K101, has a function of generating the signals which go to the control unit of the step motor(which is not subject to this patent).

For the purpose of power for the programming unit II of the apparatus. a transformer 7 is built in containing three secondary coils joined o the connectors RS1, RS2 and RS101.

For the purpose of work of the microcontroller U101 8751-PLCC, the programmable circuit U9 PLD1016 and two timer circuits U4 NE 555 and U5 NE 555, current of 5V is needed, and is received through correcting the alternative current brought by the connector RS2, by a diode corrector in a Grecz connection GZ2 joined to a condenser C15 and current stabiliser U8.

The current of +15V and -15V for powering the operational amplifiers U2A to U2C and U3A to U3C and exiting transistors Q1 to Q16 is obtained through the connector RS1, diode corrector in a Grecz connection GZ 1 teamed up with filtering condenser C13 and C14 as well as current stabilisers U6 and U7.

The current of +50V for powering the step motor is obtained through the connector RS 101 Grecz corrector GZ101 teamed with a condenser C 101. In this circuit a safety fuse RF101 is also placed as well as a diode D101 and the current is taken out by the connector RS102.

In figures 6 and 7 the constructions of the mobile and immobile parts of the vibrators III and III' of the apparatus are shown.

The immobile vibrator III' according to figure 7 is identical to the description in the patent declaration of the "Apparatus for vibrating-induced analgesia method application", made by the same person. This vibrator encompasses the casing 121, which contains an external groove 121a, where a coil of solenoid 123 is placed, and this is covered by insulating tape 127. In the middle cavity 130 of the casing 121 of the vibrator III' a hollow anchor 122 is placed, and in its inside opening a permanent magnet 124 is placed. The top of this anchor 122 contains a connection 128 with a curved tip 129. On the other side of the casing, its cavity 130 is closed of by a screw 126 screwed into the belonging hole. The screw 126 is able to be moved, by being screwed in or out when regulating the optimal amplitude of vibration. The screw contains a centred blind opening 1 26a in which a small permanent magnet 125 is placed in. In the casing 121 a lower outlet 121 b is also made for the purpose of fitting in the vibrator III' inside the parts of the shoes IV, IV'.

The mobile vibrator III, according to figure 6, differs from the immobile vibrator III' from figure 7 in shape of the casing 221. This casing 221, instead of the lower outlet 121 b from figure 7, has a longer quadratic extension 231, in which a lengthways opening 232 has been made for the purpose of passage of electric cable of the solenoid 123. At this point a

crosswise hole 233 has been made for the screw of the shoes IV,IV' for the altering of the positions of the mobile vibrators III. All the other components as well as the function of the mobile vibrators III are identical to that of the immobile vibrators III' from figure 7, because of which they are marked with the same calling marks.

In figures 8 and 9 the shoes IV,IV' are shown, and these shoes have been anatomically shaped for the left and the right foot of the patient respectively. In each of these shoes IV,IV' four vibrators are placed, two being mobile III and two not III' and they are placed in order to cover the support zones of feet. These zones are those where it is possible to simulate natural walk through vibration. For this reason the shoes IV.IV' have been made mobile so that the patient can move their feet about the axis of the shaft of the training unit. which is not subject to this patent. Due to this reason the shoes IV,IV' in figures 8 and 9 are not shown on the shaft of the training unit, where they normally are placed.

In accomplishing its function, the shoes IV,IV' are composed of the upper front part 40 in which two long openings 41 have been made and also one round opening 42 for the passage of the casings 121 and 221 of the vibrators III and III'. The shoes IV,IV' contain a round opening 44 in the upper part of the heal 43. The casings 221 of the mobile vibrators III freely pass through their openings 41, whilst the casings 121 of the immobile vibrators are fixed by their bpttom parts 121 b in openings 44 and 42.

In accomplishing the task of adjusting the shoes to the feet size of the patient, ranging from 35 to 47 European, the shoes IV,IV' have also a two part sole, which consists of the front bottom part 50 and the bottom part of the heel 51, which as shown in figure 8, are joined together by screws(which aren't shown in the figure) to their top parts 40 and 43 forming one whole. At the same time the bottom front part 50 and the bottom heel 51 are joined together by sliding cylinders 52 and 53. Cylinder 53 is placed inside and down the middle of each shoe IV,IV' and is fastened at the bottom of the heel 51. The second sliding cylinder 52 is fastened in the front bottom part of the shoe 50. To adjust to desired length of foot, the front part(40 and 50) and the back part(43 and 51) of the shoes IV,IV', are moved apart by a screw 54, which is placed on the axis of symmetry of each shoe IV,IV', appropriately placed on its outlets on both sides of the included bottom front part 50. The thread of this screw 54 is in this way fastened in a complementary thread of the tube 53 which through this is fastened in the bottom part of the heel 51. In this way, through turning the screw 54 an alteration of the distance between the front 40 and 50 and back parts 43 and 51 of each shoes IV,IV' is made possible.

For altering the desired position of the movable vibrators III inside their long cavities 41, through their threaded opening 233 they are screwed down on the complementary thread on the two ends of the screws 55 which are also able to be manipulated by hand and are axially fastened to their outlets on both sides of the included bottom front part 50. Through turning these screws 55 the mobile vibrators III are brought to the desired position according to the so-called support zones, this is done by using a before set distance between the front part, 40 and 50, and the heel part, 43 and 51, of the shoes IV,IV'.

In fastening the feet of the patient to the shoes IV,IV' during the course of the treatment, both on the front parts, 40 and 50, and the heel parts, 43 and 51, elements for fastening have been introduced, a cloth laced with sponge and velcro in the appropriate places.

These elements. which are not shown in the accompanying figures, encompass the heel holder, in the shape of the upper part of the heel 43, which is held by rivets, with belonging strapping for the fastening of feet. The left and right holders held by screws also belong to these elements, and are fastened to the upper front part 40 of each shoe IV,IV', along with belonging strapping for the fastening of feet.

The apparatus for the application of vibration biomechanics by the invention is used by firstly connecting the programming unit II to the PC computer I with the appropriate cable.

This connection is made to the printer connection on the PC computer, after this the shoes IV,IV' are joined to the programming unit II, by connect the left shoe IV to the connection on the left and the right shoe IV' to the connection on the right. After checking the position of the switch of the programming unit II, which should be on "0", the programming unit II is plugged into a power point using standard cable.

The whole system is put into normal working order through turning on the PC computer. and placing the switch on the programming unit into "1" position, at this point in time the red indicator(LED diode 21) on the left of the programming unit II will turn on. By pressing the switch 24 in upper left part of the programming unit II, the programming unit II will turn on, and the LED diode 21 on the right will turn on, signalling that the apparatus is ready for work.

Now the diskette with the appropriate programme is placed into the PC computer I and the command "VIBROAPL" is type out using the keyboard, which starts up the work programme. After the programme is read by the PC computer I a mask of the programme appears on the screen, and upon pressing the key "ENTER" a window to enter a patient's name appears. After entering the patient's name and pressing "ENTER" again. the shape of the shoes IV,IV' are shown on the screen, with the vibrators III,III' marked clearly for the purpose of the adjustment of work of each one. The adjustments are carried out using the keys "up ","down", the "up" key increasing and the "down" decreasing the strength of each vibrator III,III'. Moving from one vibrator to another is carried out through the keys "left","right", movement to the next vibrator III,III' is made using "right", whilst movement back to the previous is made using "left". Once these settings have been completed, the "ENTER" key is pressed and the options for altering the procedure, fine tuning the work of the vibrator or beginning the procedure, arise. To chose one of these the keys "Tab" followed by "ENTER" are used. Fine tuning of the work of the vibrators III and III' is carried out in the same way as the previously mentioned alterations to the strength of their work.

The alterations to the parameters of the therapy are carried out by entering the option "Procedure and pressing "ENTER". The computer gives the following parameters: frequency, amount of simulated steps per minute and the length of the treatment. The parameter frequency is adjust using the keys "F1" to increase and "F2" to decrease. The parameter amount of simulated steps per minute is adjusted using the keys "F3" to increase and "F4" to decrease, whilst the length of treatment parameter is altered by "F5" increasing and "F6" decreasing. After adjusting all these parameters of therapy "ENTER", is pressed for the therapy to be ready to start. The screen changes to a picture of a simulated patient sitting, and a sand clock which measures the time.

After all this the shoes IV,IV' are placed on the feet of the patient and strapped on.

After the shoes IV,IV' have been placed on the patient's feet, the key "ENTER" is pressed again and the therapy begins. The simulated patient on the screen begins to walk, and the time begins to run. If an audio effect of walking is needed, the key on the right hand side of the programming unit II is pressed which switches on or off the audio effect of the therapy.

Upon ending the treatment, the PC computer I stops all functions of the apparatus, and at this point in time the shoes IV,IV' are taken of the patient's feet.

The manner of applving the invention The manner of applying the invention. is achieved in an obvious way, and can be seen from the aforementioned text, and therefor is not necessary to mention. All the described characteristics of the invention have been verified by the inventors through use of the prototype of the apparatus.
