The invention relates to medical equipment and can be used to treat various types of inflammatory diseases.

Known electrotherapeutic apparatus [1], containing two channels of electrical effects of low-frequency pulse current to the organs and tissues of human rights. The drawback of the device is the limited therapeutic effect due to the non-optimal therapeutic frequency of the impinging current.

A device for laser therapy [2], comprising a generator of low-frequency noise, low pass filter, the periodic signal generator, a laser emitter and providing the elements. The disadvantage of this device is the limited therapeutic effect due to the non-optimal therapeutic frequency of the impinging radiation.

The closest in technical essence is a device that implements the method of electrotherapy [3], containing low-frequency noise current generator and catheters (in two versions). The disadvantage of this device is the limited therapeutic effect due to the non-optimal therapeutic frequency of the impinging current.

The objective of the invention is an approximation of the frequency of the current, affecting the organs and tissues of man, to therapeutic value of optimality.

The solution is achieved by the device is istwo for electrotherapy containing the noise current generator and a catheter inserted sequentially connected personal computer, a control unit and a filter unit, an input connected to the generator output noise current, the output is connected to the catheter, and a personal computer equipped with a dialog scheduling software experiment.

The technical result consists in providing the possibility of approximation of the frequency spectrum of the current acting on the organs and tissues of the human, a therapeutically optimal value by determining the optimal combination of frequency settings and the number of filters methods of mathematical planning of the experiment using a personal computer.

The drawing shows a structural diagram of a device for electrotherapy.

The device comprises a generator 1 noise current, block 2 filters, catheter 3, the personal computer 4 and unit 5 of the control.

The device operates as follows. Through the controls of the generator 1 noise current, computer keyboard 4 (not shown) and the control unit 5 sets the initial parameters of the output impact, as well as the number and frequency filter settings block 2 filters, and include the current which flows through the block 2 filters and the catheter 3 biological object and conduct of the 1st session of electrotherapy. Before beginning the scrap of the 2nd (or N-th) session determined by medical methods, the results of therapeutic effects of the 1 (or N-1-th) session for example, on a two-tier system of "positive" or "negative", which is introduced into the computer via the dialog interface of the program planning of the experiment (in the form of values taken in the program, such as +1 and -1). Upon completion of the program receive guidance programs about the recommended quantity and filters settings for 2-th (N-th) session therapy, which commands received via the control unit 5 in block 2 filters, the output of which is formed a current with the required frequency range. At a subsequent session recommendations are being repeated. This means that for a given patient and organ found the optimal number and configuration of filter unit 2 filters corresponding therapeutically optimal frequency spectrum of the current impact in this disease.

The device may be made of standard modules and on the available hardware components. Constructive execution of the blocks may overlap or include the construction of the same functional purpose of the prototype and its analogues. For example, the construction of the unit 1 may coincide with the design of the subsystem blocks 1, 2 prototype, the design of the unit 3 may coincide with construction of units 3 or 8 and 11 of the prototype. Unit 4 General purpose application dialog scheduling software the experience is of amenta, for example, package STATISTICA or STATGRAPHICS. Unit 5 managing stand-alone or built into the computer, such as a module DAQPad-1200, up to 8 channels, with service software Lab VIEW [4, 5]. Unit 2 filters - set, for example, of the eight band-pass filters, switchable between input and output unit 2 by means of electronic switches controlled by the module DAQPad-1200, and with all the filters frequency response of the unit 2 may coincide with the frequency response of the amplifier 2 prototype. The execution units is determined by their functional purpose and known or obvious from the prior art used in the time and frequency ranges.
