Title:
AUTOMATED ANALYZING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/145353
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a highly reliable automated analyzing device capable of determining an agitation state with a high degree of accuracy, regardless of differences in physical properties attributable to the materials or construction of an ultrasonic wave generating source. To this end, the automated analyzing device of the present invention comprises an agitating unit for agitating a specimen and a reagent, an analyzing unit for using a reaction solution of the specimen and the reagent to perform a component analysis of the specimen, and a control unit for controlling the agitating unit and the analyzing unit, the agitating unit comprising an ultrasonic wave generating source for generating ultrasonic waves, a drive circuit for driving the ultrasonic wave generating source, and a waveform detecting unit for detecting an electric waveform output from the ultrasonic wave generating source in conjunction with the driving thereof, wherein: the agitating unit additionally includes a harmonic component extracting unit for extracting a harmonic component from the electric waveform detected by the waveform detecting unit; and the control unit determines the acceptability of an agitation state of the agitating unit on the basis of a signal strength of the harmonic component extracted by the harmonic component extracting unit.
