DEVICE FOR DETERMINING INDICANT OF HEMATOCRIT Russian patent published in 2010 - IPC G01N33/48 G01N33/49 A61B5/145 

FIELD: medicine.

SUBSTANCE: device contains square-wave pulses generator, from its output square-wave pulse of current comes to the input of first pulse shaper and the electrodes respectively, peak detector sequentially connected through the voltage divider with a comparator. Output of the first pulse shaper is connected to the input of a microcontroller, the electrodes are connected to the input of voltage amplifier with ability to inject useful signal to it with information about rate of hematocrit level in blood. At that one voltage amplifier output is connected to the input of peak detector and to the signal input of the comparator, the other is connected to the control input of the comparator, at that the output of the comparator is connected to the input of a microcontroller connected to the information display device.

EFFECT: increase of accuracy and reduction of time of determining indicant of hematocrit.
