  • Patent number: 12146890
    Abstract: An automated analyzer includes two or more types of photometers to obtain suitable output of the measurement results of the plurality of photometers and suitable data alarm output even if there is an abnormality, or the like, at the time of measurement. The automated analyzer includes, for example, two types of photometers having different quantitative ranges and an analysis control unit for controlling analysis that includes measurement of a given sample using the two types of photometers. If two types of data alarms corresponding to abnormalities, or the like, during measurement have been added to the two types of measurement results from the two types of photometers, the analysis control unit selects measurement result and data alarm output corresponding to the combination of the two types of data alarms and outputs the same to a user as analysis results.

  • Publication number: 20240353436
    Abstract: The present invention provides an autonomous analysis device with which an operator can easily associate and confirm a reaction course and an illness. The device comprises an analysis unit for analyzing a sample, an operation unit for receiving an operation from an operator, a control unit for controlling the analysis unit on the basis of an input from the operation unit and computing measurement data using a measurement value acquired from the analysis unit, and a display unit for displaying the measurement data computed by the control unit, wherein the control unit causes the display unit to display not only measurement reaction course information that is based on the measurement data of the sample being analyzed, but also reference reaction course information that is designated by the operation unit from among items of reference reaction course information classified in advance for each illness.

  • Patent number: 11808671
    Abstract: It is necessary to efficiently agitate a small amount of sample (such as blood) and reagent (such as diluted solution) in a short time with a dispensing probe having a constant tube inner diameter. An automatic analysis device, by a dispensing probe, executes an aspiration step of aspirating a reagent from a reagent vessel; a first dispensing and aspiration step of dispensing a first liquid amount of the aspirated reagent to a reaction vessel and aspirating, from the reaction vessel, a second liquid amount of a mixed liquid obtained by mixing the reagent and the sample in the reaction vessel; and a final dispensing step of dispensing the aspirated mixed liquid and the reagent in a predetermined dispensing amount. A first liquid amount Va is less than a predetermined dispensing amount Vdil.

  • Patent number: 11796553
    Abstract: A chemical dispensing mechanism detects the liquid surface of a chemical including a chemical container mounted on a chemical disk. A calculation control unit controls the operation of the chemical dispensing mechanism. The calculation control unit performs a first raising operation, in which a chemical stored in the chemical container is suctioned by the chemical dispensing mechanism, which is then raised up to a first bubble detection position, determines whether a liquid surface is present, and outputs an alert indicating the presence of a bubble on the liquid surface when the liquid surface has been determined to be absent. The first bubble detection position is when the tip of a dispensing nozzle of the chemical dispensing mechanism remains inside the liquid when there are no bubbles present on the liquid surface, and is exposed from the inside of the liquid when there are bubbles present on the liquid surface.
