Abstract

PURPOSE: To enable the exact detection of the ratio of hemolysis by projecting the light emitted from a light emitting element of a single wavelength to a tube in which the plasma flows and receiving the light transmitted therethrough by a photosensor.
CONSTITUTION: A light emitting diode 61 having green emitted light and the photosensor 62 which detects the transmitted light thereof are disposed on both sides of a bulging part 60a of the tube 60 in which the plasma flows. The current output signal of the photosensor 62 relating to the transmitted light is then introduced via a current/voltage conversion circuit 68 constituted of an operational amplifier 64 and a resistor 66 to a comparison input terminal IN of a voltage comparator 70. The data is simultaneously taken into a RAM a microcomputer 78 via an A/D converter 72. On the other hand, the output signal of the microcomputer 78 is introduced via a D/A converter 80 to a reference input terminal REF of the voltage comparator 70. The output signal of the voltage comparator 70 is introduced to the other input terminal of the microcomputer 78. The ratio of the hemolysis is thereby exactly detected.
