RHEOANALYZER Russian patent published in 1997 - IPC

FIELD: medical engineering. SUBSTANCE: rheoanalyzer uses series-connected electrodes block 1, branch switch 2, high-frequency amplifier 3, amplitude detector 4, analog switch 5, multichannel rheosignal amplifier 6, analog switch 7, analog-to-digital converter 8, microprocessor 9, exchange unit 10, computer 11, series-connected clock pulse generator 12, frequency divider 13, counter 14 and two-port storage device 15; clock pulse generator 12 is connected to switch 2 via AC power source 16. The accuracy of measurement of electrorheograms is enhanced due to the fact that the rheosignal pick-off circuits are connected to the inputs of multichannel rheosignal amplifier 6 at the instants when current across the output of source 16 is equal to zero. EFFECT: enhanced accuracy of measurement of rheograms and expanded functional abilities due to reduction of the level of switching noise, quick change of the program of rheosignal pick-off. 4 cl, 5 dwg
