METHOD AND APPARATUS FOR CLINICAL ANALYSIS

摘要

Disclosed is a clinical analyzer comprising an analyzing section (200) having a reaction tube and photometer, and a sampling section (100) having a sample transfer pipe (201) and centrifugal separator (1) which also serves as a sampler. Sample containers (4) containing blood are set on a plurality of container holders (3a, 3b) through an aperture formed in the cover of the centrifugal separator. A rotor (2) with the container holders mounted thereon is rotated at a low speed intermittently so that each of the container holders is positioned at the container setting position in a predetermined order in which a container holder which is not located adjacently to the previously positioned container holder is positioned next. Subsequently, the rotor is rotated at a high speed for a predetermined period so that the sample liquid in each sample container centrifugally separated. After the centrifugal separation the rotor is rotated at a low speed intermittently so that the sample containers set on the container holders are positioned to the sample take-out position in the same order as in setting the sample containers. The pumping pipe is inserted through a sample transfer hole formed in the cover of the centrifugal separator into the sample container, and the sample liquid is pumped up and transported to the analyzing section. This series of operations is repeated and a plurality of samples are measured for items of analysis by the photometer sequentially.
