  • Publication number: 20240061000
    Abstract: According to one embodiment, an automatic analyzing apparatus includes processing circuitry. The processing circuitry measures an electrical potential pertaining to a contact between a probe for dispensing a sample or a reagent and a liquid surface, and outputs the measured electrical potential as a measurement value, determines whether or not the measurement value is within a specific range, and outputs a determination result, and provides a notification on a state of a liquid related to the liquid surface according to the determination result.

  • Publication number: 20210318346
    Abstract: An automated analyzing apparatus according to one embodiment comprises a barcode reader and a cylindrical lens. The barcode reader emits light toward a barcode attached to at least one of a specimen container storing a test sample, a reagent container storing a reagent to be reacted with the test sample, and a specimen rack housing a plurality of the specimen containers arranged in a line, and reads the barcode on the basis of reflected light of the applied light. The cylindrical lens is placed between at least one of the specimen container, the reagent container, and the specimen rack, and the barcode reader.

  • Patent number: 10859590
    Abstract: According to one embodiment, an automatic analyzing apparatus includes a liquid tank, a first pump, a dispensing probe, and a thermal exchanger. The liquid tank stores a first liquid. The first pump pressurizes and sends the first liquid supplied from the liquid tank. The dispensing probe uses the first liquid that is sent out from the first pump as a pressure transmitting medium. The thermal exchanger exchanges heat between an atmosphere in the automatic analyzing apparatus and the first liquid in at least a part of a first flow path connecting the first pump to the liquid tank.

  • Patent number: 9513305
    Abstract: An automatic analysis apparatus according to an embodiment incudes a dispensing probe, a cleaning unit, and a driving mechanism. The dispensing probe performs a dispensing operation for sucking a sample and discharging the sample into a reaction container. The cleaning unit cleans the dispensing probe. The cleaning unit includes a first cleaning position at which the dispensing probe is cleanable using a first cleaning liquid, and a second cleaning position which is located at a position lower than the first cleaning position and at which the dispensing probe is cleanable using a second cleaning liquid. The driving mechanism stops the dispensing probe at at least one of the first cleaning position and the second cleaning position.
