Abstract
Disclosed herein are a method and an apparatus for measuring hematocrit of flowing blood. The apparatus for measuring hematocrit of blood according to an exemplary embodiment of the present invention includes: a body part provided with a blood inlet and a blood outlet; first and second electrodes disposed on both inner side walls of the body part so as to be opposite to each other; a third electrode disposed on the same side wall as a side wall on which the first electrode is disposed while maintaining a predetermined distance from the first electrode; a measurement unit measuring first impedance of blood between the first and second electrodes and second impedance of the blood between the first and third electrodes; and a calculation unit determining the hematocrit of blood using the first and second impedances.
