AUTOMATIC ANALYTICAL METHOD AND APPARATUS FOR BLOOD

摘要

PURPOSE:To attain to miniaturize an apparatus and to enhance measuring accruacy by performing analysis of mamy items by one transfer process, by heating a disc for holding the required number of reaction tubes each having a predetermined amount of blood received therein in the transfer process while performing colorimetric measurement. CONSTITUTION:Small holes 11 are opened to a disc 10 at reguired intervals and the corresponding number of reaction tubes 12, are held in the holes 11 while an optical axis hole 13 is opened to each small hole 11 of the disc 10 in a direction crossing the axial direction of each hole 11 at right angles so as to pierce said disc 10 and measuring light from a light source K is transmitted through the serum in the reaction tube 12 through the optical axis hole 13 and again guided to the outside of the disc 10 through the optical axis hole 13. This disc 10 is held by a disc holder 15 and controlled by a rotary means 16. A required amount of serum received in the sample cup 21 of a sampler 20 provided so as to be adjacent to the holder 15 is distributed in each reaction tube 12 of the disc 10 through a pipet apparatus P and the disk 10 holding the reaction tubes 12 is heated through a thermostatic transfer path 30 to successively perform colorimetric transfer path 30 to successively perform colorimetric measurment.
