Document Type and Number:
WIPO Patent Application WO/2019/176296
Kind Code:
A1
Abstract:
Provided is an automatic analysis device that avoids carryover and prevents deterioration of analysis performance without controlling reaction cell position. This automatic analysis device is provided with: a reaction cell in which a sample and a reagent are mixed and allowed to react; a light source that radiates light onto the mixed liquid of the sample and the reagent, which has been dispensed into the reaction cell; a detector that detects the light radiated from the light source; and a cleaning mechanism that cleans the reaction cell. The cleaning mechanism includes an intake nozzle that draws in liquid from the reaction cell and a discharge nozzle that discharges the liquid into the reaction cell; the intake nozzle and the discharge nozzle can move vertically; and the intake nozzle is cleaned by lowering the intake nozzle into the reaction cell, in which a cleaning liquid or cleaning water have been accumulated, without drawing in the cleaning liquid or the cleaning water.
