Title:
AUTOMATED ANALYZING DEVICE, AND LIGHT SOURCE STABILIZATION METHOD FOR AUTOMATED ANALYZING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/070144
Kind Code:
A1
Abstract:
Provided is an automated analyzing device capable of avoiding a light intensity drift accompanying a temperature change caused by the start of energization of a light source, and capable of shortening a stabilization waiting time. An automated analyzing device 50 comprises: a light source 39 which illuminates a reaction vessel 2 accommodating a mixed solution of a sample and a reagent with light for measuring the sample; a temperature regulating mechanism 27 for performing temperature regulation of the light source 39 by means of a temperature regulating medium; a reaction tank 5 for performing temperature regulation of the reaction vessel 2 by means of the temperature regulating medium; circulating pumps 30, 35 for delivering the temperature regulating medium; an analyzing unit 42 for analyzing the sample; and an operation control unit 43. When transitioning from a sample non-measurement state to a measurable state via a measurement preparation state, the operation control unit 43, in the measurement preparation state, increases a current or a voltage applied to the light source 39, increases a flow rate of the temperature regulating medium for a fixed time period, and returns the flow rate of the temperature regulating medium to the flow rate prior to the increase, and then migrates to the measurable state and causes the sample to be measured.
