US 2022/0034928 A1 · AUTOMATIC ANALYZER

Abstract

Provided is an automated analyzer comprising an ultrasonic cleaner capable of obtaining a consistent cleaning effect regardless of the operating temperature environment. This automated analyzer comprises: a dispensing mechanism having a nozzle for dispensing a sample or reagent; an ultrasonic cleaner 26 for cleaning the nozzle; and a control unit 28. The ultrasonic cleaner comprises: a cleaning tank 206; an ultrasonic vibrator 205; and a vibration head 209 that extends from the ultrasonic vibrator to the cleaning tank and has a distal end part that is inserted into the cleaning tank. The control unit inserts the nozzle into the cleaning tank and carries out a heating operation for heating the ultrasonic vibrator by driving the ultrasonic vibrator according to a driving condition different from that for a cleaning operation for cleaning the nozzle by driving the ultrasonic vibrator.

An automatic analyzer, comprising:

a dispensing mechanism having a nozzle for dispensing either a sample or a reagent;
an ultrasonic cleaner to clean the nozzle;
and
a controller,
wherein the ultrasonic cleaner includes a cleaning bath, an ultrasonic transducer, and a vibration head which extends from the ultrasonic transducer toward the cleaning bath to cause a tip of the vibration head to be inserted into the cleaning bath, and
the controller performs a heating operation of driving the ultrasonic transducer to heat the ultrasonic transducer under drive condition which is different from that of a cleaning operation of cleaning the nozzle by inserting the nozzle into the cleaning bath and driving the ultrasonic transducer.
