Abstract

The present invention provides an automatic analyzer capable of reducing the time necessary for analysis processing by making various operations pertaining to the analysis processing more efficient. More specifically, the present invention is characterized in that, from among a plurality of ending operation items set as analysis ending operations to perform at the end of analysis operations for analyzing a sample under analysis, one or more ending operation items to be performed are selected, and on the basis of monitoring results of monitoring the status of an automatic analyzer during the period from the end of the analysis ending operations to the start of analysis preparation operations for preparing for the analysis operations, one or more preparation operation items to be performed are selected from among a plurality of preparation operation items set as analysis preparation operations.

First claim

The invention claimed is:

1. A method for controlling an automatic analyzer, comprising the steps of:
selecting a mode, which is one of a normal mode for carrying out analysis preparation operation items, in an analysis preparation operation, which are set in advance, and a time-saving mode for carrying out fewer analysis preparation operation items than in the normal mode;
monitoring one or more conditions of the analyzer between a completion of a startup processing of the automatic analyzer and a start of an analysis preparation operation for preparing for an analysis operation and between a completion of an analysis-ending operation and the start of the analysis preparation operation for preparing for the analysis operation;
determining one or more analysis preparation operation items to be carried out from the analysis preparation operation items set as the analysis preparation operation based on the selected operation mode and on the monitoring result of the one or more conditions of the automatic analyzer; and
performing the analysis preparation operation based on the determined one or more analysis preparation operation items.

2. The method for controlling an automatic analyzer according to claim 1 ,
wherein the one or more monitored conditions of the automatic analyzer include at least one of presence or absence of a malfunction which occurs during startup of the automatic analyzer, presence or absence of a malfunction during the analysis operation, presence or absence of access by the operator to an analysis unit between the completion of the analysis operation and the start of the analysis preparation operation, presence or absence of maintenance which is carried out between the completion of the analysis operation and the start of the analysis preparation operation, type of the maintenance carried out, a presence or absence of a change of a reagent used for the analysis, the elapsed time since the completion of the startup processing of the automatic analyzer or the completion of the last analysis and the elapsed time since maintenance of a system reagent.

3. The method for controlling an automatic analyzer according to claim 1 ,
wherein the analysis preparation operation items of the analysis preparation operation include at least one of an operation item of filling a reagent supply flow path for supplying a reagent used for the analysis with the reagent and an operation item of disposing of a reaction container used for the analysis operation.

4. The method for controlling an automatic analyzer according to claim 1 ,
wherein the one or more monitored conditions of the automatic analyzer includes presence or absence of replacement of a reagent used for the analysis in a reagent supply flow path for supplying the reagent with water, wherein the presence or the absence is decided based on type of maintenance which is carried out.

5. The method for controlling an automatic analyzer according to claim 1 ,
further comprising wherein a step of determining one or more ending operation items to be carried out from ending operation items set as the analysis-ending operation which is carried out when ending the analysis operation based on the set operation mode.
