FIELD: medical equipment.
SUBSTANCE: device has personal computer, electric-dermal activity detectors connected with analog multiplexer through signal amplifiers and filters, analog-to-digital converter, microcontroller connected with personal computer, galvanic decoupling unit, reference voltage source, photoplethysmography detector, piezoelectric breathe detector, electromyography detectors, electrocardiography detectors. Multiplexer is built in analog-to-digital converter. Photoplethysmography detector is connected to multiplexer through plethysmography signal amplifier and photoplethysmography signal filter. Piezoelectric breath detector is connected with multiplexer through breath signal amplifier and breathe signal filter. Electromyography detectors are connected to multiplexer through muscles biological activity signal amplifiers and muscles biological activity signal filter. Electrocardiography detectors are connected to multiplexer through heart muscle biological activity signal amplifiers and heart muscle biological activity signal filter. Galvanic decoupling unit is connected with microcontroller and with interface transformer, which is connected with personal computer. Reference voltage supply is connected with device power unit. Power unit is connected with personal computer through USB port.
EFFECT: improved precision of estimation of functional state; usage at stationary and mobile modes of operation.
