APPARATUS AND METHOD FOR MEASURING BLOOD CELL DEFORMABILITY USING ROTATING DISC

摘要

An apparatus for measuring the deformability of blood cells, and its method are provided to measure the deformability of blood cells by using a very small amount of blood within a very short time and to obtain the distribution characteristics of the deformability of various blood cells by one measurement. An apparatus for measuring the deformability of blood cells comprises a disposable disc(20) where a blood sample is accommodated; a rotatory driving mechanism(10) which contains a device rotating the disposable disc, controlling the rotation velocity and operating it; a measurement part(30) which is separated from the disposable disc and is located at the its upper part and measures the compression of blood cells; and an output part(50) which outputs the result of the deformability of blood cells measured at the measurement part. The disposable disc comprises a sample reservoir(21) where the blood sample is injected and is stored; and a plurality of capillaries(22) whose one end are connected to the sample reservoir and where the blood sample is flown and compressed. The measurement part comprises a light-measuring sensor(31) which can measure the length of the blood cells separated from plasma; and a controller(32) which processes the signal generated from the light-measuring sensor.
