PURPOSE: To measure quickly the hematocrit value of a blood with good accuracy by sealing the blood into a capillery, subjecting the blood to centrifugal sepn. to separate the blood to a serum part and a blood cell part, providing plural photodetectors of the same kind and the same size in parallel in the longitudinal direction of the capillary and detecting electrically the quantity of the transmitted light in each part.
CONSTITUTION: A blood is sealed into a capillary 1 and is subjected to a centrifugal sepn. for the purpose of early diagnosis of the jaundice of neonate, etc. and is centrifugally separated to a serum part 1a, blood cell part 1b and a part 1c where the specimem does not exist. Such capillary 1 is placed on a base having a slit through which light can transmit and parallel rays are irradiated from a light source 2 as shown by arrows to the capillary 1 in the longitudinal direction thereof. Each quantity of the transmitted light in the respective parts 1a, 1b, 1c are detected by a photodetecting device 3 disposed in parallel with plural photodetectors 3a, 3aW of the same kind and the same size. The detected signal is calculated via a driver 4 in an arithmetic circuit 5 and the hematocrit value is displayed on a display device 6 and is recorded in a printer 7. The surer and quicker measurement than the naked eyes is thus made possible.
