The standard sample remaining amount is displayed as a percentage (100% when the standard sample is fully filled with the standard sample), and standard sample information such as the expiration date of the standard sample is displayed on the monitor of the console 125.

[0008] The calibration curve information display function unit 115 displays a calibration curve obtained using a standard sample whose concentration is known in advance and information on the calibration curve on a monitor of the console 125.

The quality control information display function unit 117 displays on the monitor of the console 125, as quality control information, measurement results performed at a predetermined time interval or a predetermined number of measurements for the control of the measurement accuracy using the standard sample. .

The calibration item setting function unit 119
Is based on information entered using the console 125,

The console 125 has a monitor 127 and a keyboard 129, and includes a reagent information display function unit 111, a standard sample information display function unit 113, and a calibration curve information display function unit 1.
15. The information supplied from the quality control information display function unit 117 is displayed on the monitor 127 on separate screens. In addition, the console 125 supplies the information input by the keyboard 129 to the corresponding function units 111 to 123 or the control unit 109.

Next, a flow of a general measurement operation using the automatic analyzer 100 will be described. First, the operator performs a startup operation necessary for starting up the automatic analyzer 100, such as cleaning. Next, the setting of the reagent and the standard sample or the confirmation of the amount and the expiration date of the reagent and the standard sample are performed. Then, the operator specifies a measurement item using the console 125 and performs calibration using the standard sample. Then, the validity of the calibration curve is confirmed.
If necessary, perform calibration again to determine the calibration curve. In addition, the operator performs measurement accuracy management (qualit
A standard sample for y control (QC) is set, the measurement items and operations are specified using the console 125, and the measurement items of the measurement sample (sample) are specified. In this state, a measurement sample is placed and measurement is performed. Then, the measurement result of the measurement sample is confirmed. If necessary, re-measure and confirm the final result. In addition, a measurement result for measurement accuracy management performed at a predetermined time interval or a predetermined measurement number interval is confirmed. When the measurement of the measurement sample is completed,
Performs necessary shutdown operations at the end of work. Thus, the measurement of the measurement sample by the automatic analyzer 100 is performed.

However, in the conventional automatic analyzer, "confirmation of reagent amount and expiration date", "confirmation of standard sample amount and expiration date", "confirmation of validity of calibration curve" In such a case, there is a problem that a plurality of pieces of information cannot be checked at a time because each information display is a separate screen. For example, reagents,
In order to confirm four types of information of the standard sample, the calibration curve, and the measurement accuracy management, operations of up to four types × 2 steps = eight times are required.

When some trouble occurs and the measurement result is adversely affected, the cause is often investigated focusing on the measurement item, and the type of information to be displayed must be changed many times. There is also a problem that it takes time to respond.

There is another problem that it is not possible to set the calibration items, set the measurement accuracy management items, and limit the measurement items at the same time as the confirmation operation. Further, the operation method such as the confirmation depends on the memory of the operator, which causes mutual operation.

The present invention has been made in view of the above-mentioned problems, and has an automatic analyzer capable of simultaneously confirming a plurality of pieces of information, reducing a burden on an operator, and efficiently analyzing a sample. The purpose is to provide.

In the automatic analyzer according to the present invention, the information display management means displays at least two analysis items of the measurement sample and information on the analysis items on one screen, and the analysis items are changed by the item changing means. Then, the information is changed by the information changing means in accordance with the changed analysis item. Thereby, a plurality of pieces of information can be checked at the same time, the burden on the operator can be reduced, and the sample can be analyzed efficiently.

The display management means may include at least two of information on reagents corresponding to analysis items of the measurement sample, information on standard samples, information on calibration curves, and management information on measurement accuracy.
