Abstract

PURPOSE:To realize an automatic analyzer in which measurements are carried out automatically for registered emergency measurement items upon setting of a specimen by registering items, frequently used in emergency measurement, as emergency measurement items and providing the stage for emergency specimen with a position number detector. CONSTITUTION:Upon sitting a reagent container containing an emergency specimen in an emergency specimen setting hole in a sample holding table 10, a detector functions to notify the set position to a computer (CPU) 11. The CPU 11 takes out an emergency measurement term from a memory section 13 and registers the item with respect to the number of container holding hole. If other specimen, e.g. a general specimen, is under analysis, the CPU 11 executes a control program for interruption analysis. The table 10 is then rotated based on a command delivered from the CPU 11 to move a target specimen to a dispensing position where specified quantity of sample is dispensed through a sample dispensing mechanism 14 into a reaction container 15. Predetermined quantity of reagent is then dispensed from a reagent bottle on a reagent desk 16 through a reagent dispensing mechanism 19 and reaction results are subsequently measured through an optical system 18 thus analyzing the specimen automatically.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic analyzer, and more particularly to an automatic analyzer which allows a user to reliably register and analyze analysis items by a simple method when analyzing an urgent sample.

[0002]

2. Description of the Related Art Japanese Patent Publication No.
No. is assigned to each sample container installation position on the rotating sample holding table as described in No., and when analyzing an emergency sample, the operator erected the sample in the container installation hole for the emergency sample and confirmed the position number. After that, when the position number and the item to be analyzed are input from the operation unit, the urgent sample is registered and analyzed.

[0003]

In the above-mentioned prior art, the target sample is not analyzed due to a mistake in the installation position number or an input error, and the necessary analysis is not performed due to an item input error. There was a problem of analyzing the items. In addition, in the case of measuring an urgent sample, a person other than a dedicated operator may operate it, and it is necessary to reliably perform registration using the simplest procedure possible to start analysis urgently.

An object of the present invention is to solve the above-mentioned problems and to easily and surely register an analysis item and start analysis.

[0005]

The automatic analyzer according to the present invention can input and store items frequently used for urgent measurement as urgent measurement set items, and provide a detector at each erection position of an urgent sample. When the emergency sample is installed, the set item is registered for the sample of the position number.

[0006]

As described above, the user can surely register and analyze the analysis items stored in advance by merely installing the sample requiring the emergency measurement in the apparatus.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1, 2 and 3. FIG. 1 is an example of a sample container holding table. Each emergency container installation hole is equipped with a detector that emits a signal when the container is installed.

When there are a plurality of emergency sample container installation holes and only one kind of emergency measurement set item is stored, when a container is installed in an arbitrary container installation hole, the detector works and the emergency measurement set is set at that position. Items are registered and analyzed.

Further, having a plurality of emergency sample container installation holes,
If an emergency measurement set item is stored for each installation hole, the detector works when the container is installed in the container installation hole, and the set item corresponding to that position is registered and analysis is started.

FIG. 2 is a block diagram of the automatic analyzer shown in this embodiment, and its operation will be described. The sample container 1 accommodating the urgent sample is installed in an arbitrary container installation hole for the urgent sample on the sample holding table 2. When the sample container is installed, the detector works and informs the computer 3 of the installed position via the interface 4. The computer 3 retrieves the emergency measurement set item from the storage unit 5 and registers it for the number of the container holding hole that is installed. When another sample such as a general sample or a control sample is being analyzed, the computer 3 calculates a control program for performing the interrupt analysis, and rotates the sample holding table 2 through the interface 4 to dispose the target sample at the dispensing position. To the reaction disk, and a predetermined amount of sample is dispensed to the reaction disk by the sample dispensing mechanism 6,
A predetermined amount of a reagent is dispensed from the upper reagent bottle by a reagent dispensing mechanism 8 to cause a reaction, and an optical system 10 measures and analyzes the reagent.

When the detector of the sample container transmits its position to the computer 3, if the state of the device is measurable and no other sample is being analyzed, the preparatory operation before the analysis is immediately started and the above-mentioned operation is performed. Make emergency measurements.

Further, an urgent sample registration screen as shown in FIG. 3 is provided to confirm the container installation position number, analysis item, etc.,
Provide a function that can be changed. When the sample container 1 is installed on the sample holding table 2, the computer 3 is connected to the interface 4
The screen of the CRT 11 is switched to the screen shown in FIG. Figure 3
In a, the container installation position number and the keyboard image of the analyzable item are displayed. The key of the keyboard 12 also serves as an item selection key, and one item is assigned to one key. The keyboard image is displayed on the screen, and the color or pattern is changed to distinguish whether the item is registered or not. The above-mentioned display of the emergency measurement set item is displayed with this keyboard image. If there is a key input which means that the registration item is sufficient, the set item is registered and analyzed. When a predetermined time elapses without key input, set items are registered and analyzed. If there is a key input indicating a change in the registered item, the screen is changed to FIG. 3b to accept the change in the registered item, the updated item is registered, and analysis is performed.

[0013]

As described above, according to the present invention, it is possible to easily and reliably perform the item registration of a sample that must be analyzed urgently, so that the operator's time and labor can be saved and the operator's input error can be eliminated. , It is possible to reliably analyze the items required for emergency measurement.
