BIOTELEMETRY SYSTEM Russian patent published in 1998 - IPC

FIELD: medical engineering. SUBSTANCE: system has portable part in which casing the first transmitter is mounted having the first amplifier and modulator connected in series, the former being connected to biological information pickup with its input, and the first receiver connected to the first inductance coil with its input, and stationary part having the second transmitter having the first generator connected in series to the second amplifier and the second receiver as demodulator connected to output unit, and the second inductance coil magnetically interacting with the first inductance coil. Outputs of the first receiver are connected to power supply source inlets of the first transmitter. Modulator is connected by its output through capacitor connected in series to matching transformer to the first inductance coil and by the second input it is connected to the second generator. Demodulator is connected by its input through band-pass filter and the third amplifier to the second inductance coil that is connected to the second amplifier output through the second capacitor. EFFECT: wide range of functional applications. 28 cl, 9 dwg
