Abstract
A hematocrit measuring instrument of the type which determines hematocrit of blood from the electrical resistivity of the blood is provided with a blood resistivity measurement device, an ultrafilter for filtering a part of the plasma from the blood, a filtrate resistivity measurement device for measuring the resistivity of the filtrate from the ultrafilter and an arithmetic circuit for calculating the hematocrit of the blood from the resistivities of the blood and the filtrate. The hematocrit measuring instrument is connected into a circulatory path for the blood outside of the patient's body and continuously measures the hematocrit of the blood from the resistivity of the blood and the resistivity of the filtrate from the ultrafilter.
