Abstract
An automatic analyzer includes a plurality of reagent disks having reagent containers thereon, a reaction disk having a plurality of reaction cuvettes and a plurality of reagent dispensing probes arranged on each of the reagent disks. Each of the dispensing probes includes a first arm rotatable about a first rotary shaft and a second arm rotatable about a second rotary shaft arranged on the first arm with the arms being rotatable independently of each other. A mechanism analyzes reactions of the reagents and samples in the cuvettes.
Claims6
An automatic analyzer comprising:
- a plurality of reagent disks;
- a plurality of reagent containers being arranged along a circumference of each of said reagent disks, with rotary axes of said reagent disks being different from each other;
- a reaction disk on which a plurality of reaction cuvettes are arranged along a circumference;
- a plurality of reagent dispensing probes arranged on each of said reagent disks, each of said reagent dispensing probes sucking a reagent contained in said reagent container and ejecting the sucked reagent into a reaction cuvette, at least one pair of said plurality of reagent dispensing probes being arranged to eject the sucked reagent from the reagent container on the reagent disk into the reaction cuvette at a same dispensing position on the reaction disk;
- each of said reagent dispensing probes including a first arm operated to rotate about a first rotary shaft and a second arm operated to rotate about a second rotary shaft arranged on said first arm, said first arm and said second arm being rotatable independently of each other;
- and
- a mechanism for analyzing reactions of said reagents and samples in said reaction cuvettes.
