MEDICAL DIAGNOSTIC COMPUTERIZED CARDIOGRAPH Russian patent published in 2000 - IPC

FIELD: medical devices, in particular, for functional diagnostics. SUBSTANCE: device has high-frequency generator with electrode for modified four-pole flow measurement in two channels, each of which has differential amplifier, linear detector of mean rectified value, joint flow graphs, three low-pass filters, and two analog differential devices. Four adding and subtraction devices are inserted between channels. In addition device has acoustic cardiogram channel and two electric cardiogram channels, which outputs are connected to inputs of multiple-channel analog-to-digital converter, which is connected to computer slot. EFFECT: increased precision of measurement of current flow characteristics, increased functional capabilities, automatic processing of received data. 2 dwg
