The invention relates to medical technology and can be used in therapeutic practice, prosthetics, in controlling the formation of motor skills, in human siege is a machine.

The purpose of the invention is to expand the functionality of the device by providing an accurate synthesis of the stimulating agent in each channel.

Phi, 1 is a block diagram of a motor response controller; Fig. 2 shows a basic electrical circuit of a unit for forming scanning pulses and a programmable storage device.

The control unit for motor responses contains a generator of 1 driving pulses, a formation unit 2. scanning pulses, program memory device (block) 3, block 4 galvanic isolation, generator 5 stimulating pulses, amplifier 6 (output) and a pair of electrodes 7.

From the output of generator 1, the pulses arrive at the input of unit 2, from whose outputs the scanning pulses arrive at the sampling lines of the line of the program storage device 3 from the outputs of which are generated in accordance with the program entered into it, the pulses arrive at the inputs of the A blocks galvanic development channel channels and then to the control inputs of 1 generator 5 stimulating pulses, from the outputs of which the signal goes to the inputs of amplifiers 6, to the inputs of which electrodes 7 are connected. At the same time, the phase structure of multichannel power multiplier

of this block, the second inputs are with the trigger outputs, the output of the first NAND logic element is connected to the forward count input of the reversible counter, and the output of the second NAND logic gate is connected to the countdown input of the reverse count counter.

corresponds to the program entered into the program device 3. The number of elements of the stimulus signal decomposition during one full cycle of operation of the claimed device on each channel can be any (from 0 to the number N equal to the number of sample lines of the programmable memory 3). The maximum number of decomposition elements of the entire multichannel stimulating signal is equal to the product of the number of lines sampled by the number of channels set. roystva ,,

Block 2 contains two logical elements IS-HE 8, the first inputs of which are connected to the first inputs of which receive pulses from the output of generator 1, and, for example, I receives the second input of one logical AND element, and the second input of another logical input. element AND NONE - O respectively. with direct and inverse outputs of the trigger 9. Thus, in. according to the logic of the logic elements 8, the drivers and mylces. arrive only at the input of the direct counter 0. When the trigger trigger state 9 changes, the driving pulses go to the reversing input of the counter 10.

The trigger input and the zero setting input of the counter 10 are connected to the outputs of block 3.

From the outputs of the counter 10, the status information presented in binary code goes to the decoder 11, which is decrypted into a ten-code. In the initial state, when the state of the counter is zero, the level O is present only at the zero output of the decoder, and all other outputs (1-9) are in a state with high resistance. When the first pulse arrives at the direct input of the counter 10, it goes into one state, and the decoder decrypts this state so that the state O appears at the output of the decoder 11, and the remaining outputs have a high impedance. Similarly, when the second pulse arrives at the input of the 10 O counter, it appears at the other output of the decoder upon receipt, the third pulse — at the third output, etc. until nine. After that, the whole cycle is repeated. Thus, O successively appears at the outputs 2. When the driving pulses arrive at the reversing input of the counter 10, the states of the counter 10 and the decoder 11 change in the reverse order (O, 9,8,7, ... 2, one).

Software memory 3 is a matrix of switches 1.2 located at the intersections of the row sampling lines and the output lines. Programming is done by translating the 12V switches. desired position. Horizon-

The long lines on the diagram are the sample lines, the vertical lines are output lines. Diodes 13 are used to isolate the row sampling lines when the switches 12 of the same output line are connected to different row sampling lines.

Line sampling lines in the diagram are connected to the outputs of block 2 through the NOT 14 logic elements. When using, for example, K155IE6 chips and the K155ID1 decoder in block 2, the logic elements 14 in block 3 should be deleted or included in each sample line of the line two elements 14 in series. However, when used in block 2 as a counter 10, a binary reversible counter of the type K155IE7 and a decoder of the type KG55IDZ (for 16 positions) changes in the circuit of block 3 are not required. At the same time, the number of lines in the row is increased to 16, and with it the number N also increases.

The proposed device improves the functionality and accuracy of multi-channel stimulating effects.
