  • Patent number: 11971424
    Abstract: An automatic analyzer is provided which is easier to investigate when some troubles such as data abnormality occur in a sample analysis result as compared with an automatic analyzer according to the related art. The automatic analyzer includes: analysis units that perform analysis and quality control analysis for ensuring quality of the analysis; a storage medium that stores quality control results of the quality control analysis performed by the analysis units; a monitor that displays the quality control results; and a control PC that controls an operation of the analysis units (8, 9, and 16), executes, when an arbitrary result is selected from the quality control results stored in the storage medium, based on the selected quality control result, statistical calculation of the selected result and a quality control result performed in the past, and causes the monitor to display a statistical calculation screen as a statistical calculation result.

  • Patent number: 11879902
    Abstract: An object of the present invention is to provide a test method capable of efficiently performing a step of evaluating a surface state of a dispensing probe provided in a dispensing apparatus. In the test method according to the present invention, a first solution in which a coloring matter is dissolved is dispensed to a first container in advance by a first dispensing probe, a second solution in which a coloring matter is not dissolved is dispensed to a second container in advance by the first dispensing probe and then the first solution and the second solution are respectively sucked and discharged by a second dispensing probe. After that, a surface state of the second dispensing probe is evaluated by acquiring an amount of the coloring matter collected by the second solution (see FIG. 2).

  • Publication number: 20210208176
    Abstract: The invention is directed to an automatic analyzer in which information necessary for reagent management is displayed without a decrease in the number of reagents capable of being displayed on the same screen and browsability of reagent information is improved. A display area is compressed by limitation of the number of display items per reagent and the amount of text to be displayed on a first screen, and reagent management items capable of being displayed per screen are magnified by arranging and displaying respective reagents in a matrix form. The respective reagent management item displaying areas are selected using buttons formed at the respective displaying areas, whereby a detailed information display screen of a target reagent is displayed.
