AUTOMATIC ANALYZING DEVICE

摘要

A rinse mechanism rinses reaction cuvettes with first and second detergents. An R1 reagent pipetting mechanism 8 rinses the reaction cuvettes that have been rinsed by the rinse mechanism with a special detergent. A counting unit counts and stores in a storage unit a use frequency of each reaction cuvette for a specific reagent item. A determining unit determines whether the counted use frequency exceeds a predetermined threshold N1. A control unit controls the R1 reagent pipetting mechanism such that, in a case where the counted use frequency exceeds the predetermined threshold N1, the reaction cuvettes, which have exceeded the predetermined threshold N1, are soaked with the special detergent only for a period equal to or less than a value derived by multiplying a pipetting cycle time, which indicates a period when a sample is pipetted, by the total number of reaction cuvettes and a predetermined integer.

1. An automatic analyzing device comprising:
a retaining mechanism that retains a plurality of reaction cuvettes; a rinse mechanism that rinses the reaction cuvettes with a first detergent and a second detergent; a detergent feeding mechanism that feeds a third detergent to the reaction cuvettes that have been rinsed by the rinse mechanism; a storage unit that stores a use frequency of each reaction cuvette for a specific reagent item; a counting unit that counts and stores in the storage unit the use frequency of each reaction cuvette for the specific reagent item; a determining unit that determines whether the counted use frequency has exceeded a predetermined threshold N1; and a control unit that controls the detergent feeding mechanism such that, in a case where the counted use frequency exceeds the predetermined threshold N1, the reaction cuvettes, which have exceeded the predetermined threshold N1, are soaked with the third detergent only for a period of time equal to or less than a value derived by multiplying a pipetting cycle time, which indicates a period when a sample is pipetted, by the total number of reaction cuvettes and a predetermined integer.
