Abstract

PURPOSE:To measure a hemtocrit value rapidly and automatically, by determining the specific volume of blood cell part composing the blood, i.e., the hematocrit value with the use of the solution conductivity of the blood, giving attention to the face that the solution conductivity of the blood changes with the specific volume of the blood cell part. CONSTITUTION:Electrode plates 4 of a probe 2 are immersed in a vessel 1 in which a blood sample collected from a patient is placd. In case when an alternate potential from an alternate current source 6 is impressed via a reference resistor 7, a potential reduction proportinal to the solution conductivity between the electrode plates 4 occurs at the terminal of the reference resistor 7. The potential reduction is expressed in terms of a hematocrit value by an amplifier 8, is indicated by an indicator 9, and is recorded by a recorder 10. Hematocrit values obtained from the conductivity of the blood by the present invention are very highly coincident with those by microhematocrit method.
