DEVICE FOR CONTROL AND EVALUATION OF PHYSIOLOGICAL PROCESSES Russian patent published in 2010 - IPC A61B5/205 A61B5/16 A61B5/432 G06F19/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to devices of medico-biological purpose, intended for registration and evaluation of fast-proceeding physiological reactions, emerging as response to produced stimuli. Device contains microcontroller, analogue-digital converter (ADC), first commutator, sensors of breast breathing, abdominal breathing, skin-galvanic response, arterial pressure, cardio-vascular activity, sensor of motor activity, power unit, preliminary amplifiers, signal amplifiers, filters, first and second digital-analogue converters (DAC), tool amplifier and unit of connection with personal computer, supplied with galvanic attenuator. Via amplifiers and filters sensors are connected with corresponding inputs of commutator whose controlling input is connected with first microcontroller bus, and output - with first input of tool amplifier. Second input of tool amplifier is connected to output of first DAC, third input - to output of second DAC, and output - to ADC input. Inputs of first and second DAC and group of inputs-outputs of ADC are connected with second microcontroller bus, whose third bus is connected to unit of connection with personal computer. Additional channel has possibility of connection to its input of face mimics sensor, piezoplethysmogram or variable component of skin-galvanic response and includes second electronic commutator, to whose outputs subchannels of processing of signals from corresponding sensor are connected. First subchannel includes successively connected preliminary amplifier and filter, second subchannel - preliminary amplifier, filter, signal amplifier and additional filter, and outputs of subchannels via third electronic commutator are connected to first commutator input. Controlling input of third commutator is connected with microcontroller.

EFFECT: registration of maximal number of physiological parametres and ensuring objectivity of obtained information.
