Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to an automatic analyzer.

[0002]

2. Description of the Related Art In an automatic analyzer used for analyzing a biological sample such as blood or urine, a sample is dispensed into a reaction container, and a reagent is further dispensed into the reaction container into which the sample has been dispensed.
As a result, the sample reacts with the reagent, and the reacted reaction solution is measured, for example, optically, whereby the analysis items in the sample are analyzed. The reagent is stored in a reagent bottle, and this reagent bottle is held in a drive type reagent disk also serving as a cool box or in a fixed reagent cool box.
A bar code label including reagent bottle information such as an item name, a size of the reagent bottle, a type of the reagent, and an expiration date of the reagent is attached to an outer surface of the reagent bottle.

In the case of a drive type reagent disk, an operator installs a reagent bottle in the reagent disk, and when the installation is completed, the reagent disk automatically starts to be driven with a signal.
The barcode information reading device provided in the disk stores the reagent bottle information and the installation position of the reagent bottle in the device. For information on the location of reagent bottles,
It can be confirmed on the screen or printed out paper. Further, in the case of a fixed-type reagent cool box, an operator manually inputs a position for installing a reagent bottle from an operation unit. A known example of the automatic analyzer employing the former method is disclosed in, for example, JP-A-6-64070.

When an analysis operation is started, reagents necessary for analyzing a certain item are consumed. In order to manage the amount of remaining reagents in the reagent bottles, that is, the number of remaining tests that can be analyzed, the number of remaining tests is displayed, or a warning is output when the number of remaining tests decreases. A known example of an analyzer employing this method is disclosed in, for example, JP-A-5-109.

In the case of an automatic analyzer having only one analyzer, it is only necessary to confirm at which position in the reagent disk or the reagent bottle storage case, a plurality of analyzers are required. In the case of a large-sized automatic analyzer having an analysis unit, it is necessary to confirm which analysis unit is to be installed at which position in the reagent bottle storage. That is, since there is not one analysis unit, which analysis unit is involved. For example, when a plurality of reagent bottles of the same type required to analyze a certain item are simultaneously installed in reagent bottle storages of a plurality of analysis units,
When the operator confirms the analysis section number and the number of the installation position in the reagent bottle storage on the screen for each reagent bottle,
In order to install the reagent bottle, the user has to move to the bottle installation position several meters away from the screen, and the reciprocation between the screen and the reagent bottle installation position is very troublesome. There is also a method of setting the reagent bottle while standing in front of the reagent bottle storage while checking the printed paper with the information on the reagent bottle setting position. Often they are installed by mistake.

[0006] During the analysis operation, when the remaining amount of the reagent is low and it is necessary to replace the reagent bottle, it is determined from the information on the remaining amount of the reagent displayed on the screen which reagent bottle in which reagent bottle storage should be replaced. Check and move to the reagent bottle installation location to replace the reagent bottle. For this reason, the reagent bottle may be erroneously replaced with a reagent bottle different from the reagent bottle that should be replaced.

An object of the present invention is to provide an automatic analyzer that can improve the working efficiency when setting or replacing a reagent bottle and can reduce erroneous placement of a reagent bottle.

[0008]

According to the present invention, a bar code reading device reads bar code information attached to the outer surface of a reagent bottle, thereby displaying a display portion indicating a location where the reagent bottle is set. It is provided near the reagent bottle installation position. This display portion is a display lamp provided near each reagent bottle installation position,
This lamp is turned on or off.
Alternatively, the display portion displays the reagent bottle installation position by digital numbers.

According to this, when setting the reagent bottle, it is not necessary to confirm the set position on a screen apart from the reagent bottle installation position, and the installation position can be known at a glance, and the reagent bottle can be erroneously set to a different installation position. Can be prevented. Therefore, the work efficiency at the time of installing the reagent bottle can be improved, and the reagent bottle can be accurately installed.

[0010] In the present invention, in order to manage the remaining amount of the reagent in the reagent bottle, when the remaining amount of the reagent in the reagent bottle reaches a predetermined amount, a display portion indicating the installation position of the relevant reagent bottle is provided. Are provided near the reagent bottle installation position. This display portion is a display lamp provided near each reagent bottle installation position, and this lamp is turned on or off. Alternatively, the display portion displays the reagent bottle installation position by digital numbers.

[0011] According to this, when the remaining amount of the reagent becomes small during the analysis operation and the reagent bottle must be replaced,
The reagent bottle to be replaced can be checked at a glance at which reagent bottle storage position and which position, and it is possible to prevent the reagent bottle from being replaced by a wrong reagent bottle by mistake. Therefore, the work efficiency at the time of replacing the reagent bottle can be improved, and the reagent bottle can be set accurately.
