DEVICE FOR SIMULTANEOUS MEASUREMENT OF WHOLE BLOOD VISCOSITY, HEMATOCRIT, AND ERYTHROCYTE DEFORMABILITY

摘要

Disclosed is a measurement apparatus. A measurement apparatus according to an embodiment of the present invention comprises: a flow path through which blood of which the viscosity is to be measured and a reference fluid having a reference viscosity flow and form a boundary surface; and a plurality of arrays each comprising a plurality of channels which have the same width and through which the blood and the reference fluid pass, wherein the plurality of arrays are spaced apart in a direction which intersects the flow direction of the blood and the reference fluid, and the width of the channels comprised in the plurality of arrays gradually decreases in the flow direction. Also, a measurement apparatus according to an embodiment of the present invention further comprises a second measurement apparatus comprising an inlet through which blood is introduced, an electrode for obtaining impedance data of introduced blood, and an outlet through which blood is discharged, wherein the outlet of the second measurement apparatus is in communication with a first inlet passage of the measurement apparatus, and the blood discharged through the outlet of the second measurement apparatus passes through the first inlet passage and moves to a flow path which forms channels. Accordingly, integrative blood analysis of a viscosity change of blood and the cause of the viscosity change can be made by electrically measuring hematocrit and erythrocyte deformability of blood using the second measurement apparatus which includes the electrode and is coupled to the measurement apparatus.
