As an example, in an automatic analyzer using an antigen-antibody reaction, a means for dispensing a sample, Means for transporting a container containing a reagent for measurement, means for controlling the temperature of the container into which a sample has been dispensed and reacting the sample with the reagent, means for dispensing a reagent or a cleaning solution, and the container after the reaction Means for detecting light emitted from the light source.

Parameters for operating each means 100 provided in the analysis apparatus are stored in the parameter storage means 10, and the parameters are stored in the parameter storage section 22 of the parameter change means 20 when the analysis apparatus is started up (when the application is started). The parameter stored in the storage means 10 is read. The parameter is changed by a changing unit 21 included in the parameter changing unit 20. After the parameter changed by the changing unit 21 is stored in the parameter storage unit 22, the control instruction unit 23 of the parameter changing unit 20 acquires the changed parameter, and the control instruction unit 23 analyzes the changed parameter based on the changed parameter. The operation is instructed to each means 100 provided in the above. Operation information by the changing unit 21 and the control instruction unit 23 is stored in an operation information storage unit 24 included in the parameter storage unit 20. The parameters before and after the change stored in the parameter storage unit 22 and the operation information stored in the operation information storage unit 24 are read by the determination unit 25 included in the parameter changing unit 20, and the parameters and the operation information are displayed on a display unit (not shown). ) Is displayed. After confirming the display contents, if there is no problem, a confirmation operation is performed. Note that the confirmation unit 25 has an input unit for inputting additional information such as the date and time of change, the name of the changer, and the content of change (purpose), and performs a confirmation operation after inputting the additional information. The parameter stored in the parameter storage means 10 is updated to the parameter determined by the determination unit 25 by the determination operation.

  After the parameter change is confirmed by the confirmation unit 25, the changed parameter and the incidental information (change date / time, changer name, change content) input by the confirmation unit 25 are stored in the parameter change history recording unit 30. The parameters stored in the parameter change history recording means 30 and the accompanying information are read by the parameter change history confirmation means 40, and the parameters read from the parameter change history recording means 30 by the history display section 41 of the parameter change history confirmation means 40 are read. , And a history of the accompanying information are displayed. This allows the user to confirm the parameter change contents. When a parameter is rolled back, since the parameter history is stored in the parameter change history recording unit 30, the history is read and stored in the parameter storage unit 10 by the update unit 42 included in the parameter change history confirmation unit 40. You can easily roll back by updating the parameters that have been used.

  The present invention provides an analyzer equipped with means necessary for analyzing a sample, parameter storage means for storing parameters for operating the means, change of parameters read from the parameter storage means, and change of the changed parameters. A parameter changing means capable of instructing the operation of the means based and displaying the changed parameter and the operation information based on the changed parameter and inputting the auxiliary information of the changed parameter; and the parameter for storing the changed parameter and the auxiliary information A change history storage means and a parameter change history confirmation means for displaying the changed parameter and the accompanying information are provided.

  In the analyzer according to the present invention, when confirming the change of the parameter, the parameter changing unit displays the parameter before and after the change and the operation information based on the parameter, so that the operator can confirm whether the parameter is changed by the intended adjustment. And inappropriate parameter changes can be suppressed.

  Further, the analysis apparatus of the present invention can input incidental information (parameter change date / time, parameter changer name, parameter change content (purpose), etc.) related to the parameter by the parameter changing means. Since the incidental information is recorded in the parameter change history storage unit, a set of parameters and the incidental information can be managed as history information. Therefore, by confirming the history information, it is possible to confirm when and who changed the parameter for what purpose.

  Furthermore, the analysis apparatus of the present invention can easily roll back the parameters by reading the parameters stored in the parameter change history storage means and updating the parameters stored in the parameter storage means based on the parameters.
