  • Publication number: 20250076330
    Abstract: According to one embodiment, a measuring chip includes a chip body, an aspiration port, a plurality of terminals, and an attaching portion. The chip body accommodates a sample or a mixture liquid obtained by mixing a reagent that reacts with the sample or a diluent that dilutes the sample with the sample. The aspiration port is provided in the chip body and aspirate the sample or the mixture liquid. The plurality of terminals is provided in the chip body and measure a concentration of a target substance in the sample or the mixture liquid aspirated from the aspiration port. The attaching portion attaches the chip body to a transporter of an automatic analyzing apparatus.

  • 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.

  • Publication number: 20090114538
    Abstract: An example of the present invention is an automated biochemical analyzer which executes a process of analyzing a sample to be tested. The analyzer includes, an electrolyte detection unit which measures ions in the sample, a constant temperature bath which holds a solution mixture of the sample and the reagent at a predetermined measurement temperature, a cleaning unit which executes a cleaning process of cleaning at least one of parts used in a process of analyzing the sample, an analysis unit which executes an analysis process on at least one liquid of an additive to be added to the constant temperature bath, a cleaning solution to be used in the cleaning process, and an electrolytic solution to be used in the electrolyte detection unit, and acquires an index for representing properties, and a control unit which determines whether the index falls within a preset appropriate range.
