Device for measuring blood component and method of use thereof

Abstract

Abstract PURPOSE:To enable quick and exact measurement of blood components by placing capillaries into each of which the whole blood specimen is sealed on the slits of a disc-shaped rotor provided radially with the slits, subjecting the blood to centrifugal sepn. then irradiating light through the slits and converting photoelectrically the transmitted or reflected light. CONSTITUTION:Plural slits 5 are provided radially to a disc-shaped rotor 1 and capillaries 6 into each of which the whole blood specimen is sealed are placed on the chambered parts 5a of the slits then a cover 8 (shown by a dotted line) is put thereon and the entire part is concealed with cover 7. Such rotor 1 is attached to the revolving shaft 3 of a driving body 2 and is rotated to separate centrifugally the blood in the capillaries 6, by which the blood is centrifugally separated to a serum part (transparent part) and a blood cell part (shown by diagonal lines). Light is irradiated from a light source 13 to the capillaries 11 after the centrifugal sepn. and the transmitted light (may be the reflected light by providing the light source under the rotor 1) is photoelectrically converted by a photodetector 14 provided with a suitable filter 20 and is displayed or recorded on or in a display 18 or printer 19 via a preamplifier 15, a logarithmic amplifier 17 and an arithmetic path, by which the measurement of the serum components such as, for example, hematocrit value, etc. with good accuracy is made possible.
