Abstract: Provided is an automatic analysis device that enables a reagent to be reliably loaded in and loaded out within a stipulated amount of time, even during analysis and without stopping the analysis, and that enables a reagent to be exchanged without causing a long wait for the operator. Provided is the automatic analysis device that comprises the following: a reagent cooling box that cools and holds a plurality of reagent containers, and that accommodates therein a reagent holder for movably holding the reagent containers which are inside the reagent cooling box and a reagent loader for loading the reagent containers into and out of the reagent cooling box by moving in a vertical direction with respect to the reagent cooling box; a reagent cooling box cover that covers the upper surface of the reagent cooling box and that has an opening through which the reagent loader can pass; an instruction means that provides instructions for the movement of the reagent loader; and a control device that includes, within the time of one cycle, a first time slot in which an operation for analysis is carried out and a second time slot in which an operation for the loading in or out of the reagent containers is carried out, and that executes control so that the reagent loader is not moved if the driving of the reagent loader was instructed by the instruction means in the second time slot.

Abstract: The mixing of reagents with each other in the reagent storage flow paths of an automatic analyzer is suppressed before and after exchange of the reagents, which are capable of being replenished without stopping analysis. An exchangeable reagent container that accommodates a reagent is connected to a reagent storage flow path that stores a portion of the reagent. The reagent storage flow path has first and second flow paths in which the second flow path is branched from the first flow path. A reagent syringe applies a negative or a positive pressure to the first and second flow paths; and a valve controls the flow path through which the reagent is sent. As a result, the reagent supplied to a measurement portion at a predetermined timing is switched from the reagent container to the reagent storage flow path wherein the reagent can be supplied without stopping analysis.

Abstract: An automatic analysis device is provided with a reagent container disk, a reagent loader (6), a reagent loader position sensor, an RFID antenna, a memory unit, a reagent loading switch (26), and reagent load position LEDs (21-25). The reagent loader (6) has a plurality of slots for inserting reagent containers (4) and moves between the outside and the reagent container disk. The reagent load position LEDs (21-25) display determination results for each slot indicating whether the reagent accommodated in the reagent container inserted into the slot or the slot can be used on the basis of the presence of a reagent container in the slot and the reagent state of the inserted reagent or the state of the slot.

Abstract: A display unit displays, on a single screen, a first display area configured from a first area corresponding to the position on a reagent disc at which a reagent container is disposed and a second display area configured from a second area corresponding to the position on a reagent loader at which a reagent container is disposed. A control unit changes the display state of the first area on the basis of whether a reagent container is placed at a position on the reagent disk corresponding to the first area and reagent information for the reagent accommodated in the placed reagent container and changes the display state of the second area on the basis of whether a reagent container is placed at a position on the reagent loader corresponding to the second area and reagent-container-conveyance-state information for the placed reagent container.
