DATA COLLECTION SYSTEM Russian patent published in 2016 - IPC A61B5/04 

FIELD: medicine.

SUBSTANCE: method of data collection is carried out using system of registration of signal describing difference between first signal received on surface of biological tissue of patient's body, and second signal received in "air" or common surrounding region of space different from patient's body tissue. Creating first and second non-sticking electrodes, having capacitive bond or electrically conducting connection with surface and with region of space different from surface. Electronic circuit is created between first and second electrodes. First and second screens are created between first and second electrodes and electronic circuit. Third screen is created around electronic circuit. Controlled potential of first and second screens so that these potentials are repeat signals present on first and second electrodes respectively. Difference between signals at first and second electrodes, respectively, is determined and transmitting data, which indicates this difference, to external with respect to signal recording system equipment. Electronic circuit comprises first generator and first amplifier, as well as second generator and second amplifier to inputs of which signal from first and second electrodes is supplied. Outputs of first and second generators are connected to screens of first and second electrodes respectively. Electronic circuit comprises differential amplifier, first and second inputs of which are connected to outputs of first and second amplifiers. Output signal of differential amplifier shows difference of signals.

EFFECT: possibility to set gain of signal on the electrode irrespective of gain of signal, which controls screen.
