BIOCONTROLLED DEVICE FOR GENERATION OF SIGNALS SIMILAR TO EEG Russian patent published in 2009 - IPC A61N1/00 

FIELD: medicine.

SUBSTANCE: device concerns medical equipment and can be used for psychoemotional correction of patients with a psychosomatic pathology, at treatment of additive conditions, at attention deficit disorder and hyperactivity at children. The biocontrolled device for generation of signals similar to EEG, contains voltage changers, analogue-digital converter (ADC) having pulse and breath converters connected to it through amplifiers. The first and second digital ADC outputs are bridged to the first and the second digital inputs of the microcontroller. The output of the block of function keys is included on the first analogue input of the microcontroller. Third and fourth digital ADC outputs are bridged in the form of a feedback to a digital input of the amplifier of the converter of pulse and a digital input of the amplifier of the converter_: respirations accordingly. The first digital output of the microcontroller is bridged to a digital input of the display. The analogue output of the display is connected to the second analogue input of the microcontroller. The second digital output of the microcontroller is included on an input of the digital-to-analogue converter (DAC). The third digital output of the microcontroller bound to the converter of polarity of signals. Analogue DAC output is connected through the converter of polarity of signals and the filter of low frequencies to electrodes bridged in series placed on a head of the patient. The aforementioned microcontroller has the program which provides possibility of cyclic functioning of the device with a cycle time interval in 360 ictuses where duration of influence - 300 ictuses and a pause - 60 ictuses, and also the programmed digital analogues of signals similar to EEG in a kind of alpha and beta spindles with frequency of 7-13 Hz and 14-26 Hz contains.

EFFECT: optimisation of CNS neurodynamic mechanisms and correction provision of a functional condition of patients.
