Patent ID: 8753572

Claim:
An automated analyzer comprising: a nozzle which suction a reagent and a reaction solution generated by mixing a sample, magnetic particles, an antibody that binds the magnetic particles to a substance in the sample that is to be measured, and a labeled antibody including a labeled substance, where the nozzle has a stationary position; a measuring unit which quantitatively determines the substance to be measured in the sample, where the measuring unit is directly connected with the nozzle; a reaction solution/reagent transport mechanism on which a reaction vessel that accommodates the reaction solution, more than one reagent vessel that each accommodates a reagent necessary for analysis, and a nozzle cleaning region are mounted on a retainer, and which integrally transports the reaction vessel, the more than one reagent vessel and the nozzle cleaning region by moving the retainer in accordance with a particular phase of the analysis, such that the reaction solution/reagent transport mechanism transports the reaction solution and the reagent necessary for analysis to a position at which the nozzle is adapted to suck the reaction solution or one of the reagents necessary for analysis; a reaction disk which accepts a plurality of reaction vessels which accommodate the reaction solution; and gripping means for gripping and carrying the reaction vessel; wherein the gripping means carries the reaction vessel containing the reaction solution to be measured, from the reaction disk to the reaction solution/reagent transport mechanism, then after the nozzle has sucked the reaction solution, removes the reaction vessel from the reaction solution/reagent transport mechanism, and returns the reaction vessel to the reaction disk, for disposal.
