Abstract: To provide an automated analyzer capable of shortening analysis time. The automated analyzer includes a vessel which contains a mixed solution of a specimen and a reagent; and a control unit which controls a first operation performed on the vessel, a second operation performed on the vessel after the first operation, and a third operation performed on a predetermined mechanism of the automated analyzer before the second operation, in which the control unit performs the first operation and the third operation in parallel. Alternatively, the automated analyzer includes a control unit which controls a first operation performed on the vessel, a second operation performed on the vessel after the first operation, and a third operation performed on a predetermined mechanism of the automated analyzer after the first operation, in which the control unit performs the second operation and the third operation in parallel.

Abstract: An automatic analysis device includes a probe that performs a dispensing operation including a suction process and a discharge process with respect to liquid; a syringe that generates a pressure change for dispensing liquid at the probe; a flow path that connects the probe and the syringe with each other; a pressure sensor that measures the pressure change in the flow path at the time of liquid dispensing; a storage portion that stores a pressure change of time-series when reference fluid is discharged as a reference discharge pressure waveform; and a determination portion that determines whether or not there is an abnormality in the suction process of the sample from a relationship between a value of difference or a ratio between the reference discharge pressure waveform and the pressure waveform of a determination target at the time of discharge of liquid and normal range.

Abstract: There is provided an automatic analysis device that can easily realize introduction and replacement of additional reagents in operation even in a small-scale configuration. The automatic analysis device includes a reagent dispensing mechanism 107 that dispenses a reagent from a reagent container 113 containing a reagent, and a normal reagent storage portion 130 that stores a reagent container and an additional reagent storage portion 111. The normal reagent storage portion 130 is positioned in a normal movable area 132, which is a portion of a movable area 131 of the reagent dispensing mechanism 107 and the additional reagent storage portion 111 is positioned in an area excluding the normal movable area 132 in the movable area 131 of the reagent dispensing mechanism 107. The reagent dispensing mechanism 107 performs an access operation in the normal movable area 132 in the normal operation and performs an access operation to the additional reagent storage portion 111 upon receiving a predetermined instruction.
