Abstract

PURPOSE:To enable efficient and automatic analysis of multiple items at a high speed with many specimens by providing plural units of turntables on which plural reaction tubes are circumferentially placed, disposing specimen dispensers and reagent dispensers thereto and driving these. CONSTITUTION:A rack 14 is intermittently fed by two specimen vessels each, and both turntables 12 are intermittently rotated by each angle corresponding to one reaction tube in synchronization with the feed of said rack 14. A specimen (a) is dispensed successively from a specimen vessel 13-1 to the reaction tube 11 on the turntable 12-1 by a specimen dispenser 16-1 during this time and at the same time, a specimen (b) is dispensed successively from a specimen vessel 13-2 into the reaction tube 11 on the turntable 12-2 by a specimen dispenser 16-2. A reagent is successively dispensed by reagent dispensers 19-1, 19-2 into the tubes 11 dispensed therein with the specimen (a) or (b). The latter of the number of inspection items and the number of inspection processings can be preferentially analyzed in this case. If the specimens (a) and (b) are the same specimen, the processing for twice the number of the inspection items is made possible and the time required for the inspection is halved.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic chemical analyzer that performs multi-item analysis on a large number of specimens at high speed and efficiently.

In automatic chemical analyzers, the maximum number of tests that can be processed per unit time is determined by each device. For this reason, increasing the number of test items will inevitably reduce the number of specimens that can be processed per unit time, and conversely, if you try to increase the number of specimens that can be processed per unit time, the number of test items per specimen will decrease. Therefore, the characteristics of each device are characterized by the number of test items and the number of specimens.

However, in the conventional apparatus shown in Fig. 3, each sample is dispensed into reaction tubes for each test item, and then
The process moves on to the next sample dispensing operation, and it was not possible to select which of the number of test items or the number of samples processed should be prioritized for the entire device. 41st
The device shown in Z typically has 4
Three blocks of reaction tube racks (21) constituting one reaction line are used for testing 12 items of one sample, while reaction tube racks (201 block) are used as reaction tubes (11) for testing up to four items of one sample. By doing so, the number of sample items can be reduced to the usual number, and the sample processing capacity can be tripled.In Figs.

In this way, in the device shown in FIG.
You can choose which of the test items or the number of samples to give priority to. However, when using such a device,
4 reactions in 1 block of reaction tube rack Qυ! (11)
For example, even when two or more test items are required for one sample, the analysis time is the same as when analyzing all four items. Therefore, with such an apparatus, efficient and optimal analysis operations cannot be performed, and there are difficulties in high-speed processing.

Therefore, the present invention makes it possible to select which of the number of test items or the number of specimens to be prioritized when performing automatic chemical analysis, and to perform optimized high-speed processing. The aim was to provide an automated chemical analyzer that could perform the following tasks.

Hereinafter, the configuration and embodiments of the present invention will be explained based on FIGS. 1 and 2.

The automatic chemical phase separation device according to the present invention comprises a plurality of reaction tubes (
A plurality of turntables (12) are provided on which 11) are placed in a circumferential manner, and each turntable (12) divides the sample contained in the sample container (13) into the reaction tubes (1). A sample dispenser (16) TL for dispensing, a book, and a reagent container (
A sample container in which one or more reagent dispensers (111) are arranged for dispensing the reagents contained in 17) into reaction tubes (1]), and one or more types of samples are individually accommodated. 03) on the rack 0 rack, and 2
One reagent container (17) each containing more than one reagent.
Alternatively, the sample container group (18) arranged in two or more rows can be made common to all turntables, and the four racks can be moved according to the progress of the sample dispensing operation (specimen container 03). The present invention is characterized by the provision of a mechanism in which the container is intermittently fed one container at a time, and the same number of containers as the turntable (+2).

Figures 1 and 2 (well, they are schematic diagrams for explaining the configuration and operation of an automatic chemical analyzer that is an embodiment of the present invention. Of these, Figure 1 shows two turntables ( 12) shows the case where different specimens are tested, and FIG. 2 shows the case where the same specimen is tested with two turntables (b)). Note that although FIGS. 1 and 2 show the case of two turntables Ot+ for the sake of convenience in the following explanation, the number of turntables Ot+ is not limited to two.

First, in the case shown in Figure 1, the rack 0↓) is intermittently fed by two sample containers, and both turntables 02) are fed by the rack 04) by an angle corresponding to one reaction tube. Rotates intermittently in synchronization with During this time, the sample dispenser (16-1) transfers the sample a from the sample container (13-1) containing the sample a to the turntable (12-1).
At the same time, the sample a is sequentially dispensed into the reaction tube (11) placed in・Sequentially dispense the samples into the reaction tubes (11) placed on the table (12-2). Then, the reagent dispenser (19-1), (1
9-2), the reagent corresponding to the test item is dispensed from the reagent container (]7). Note that the reagent container (17) is placed on the movement lane (A) so that it can be freely moved left and right. In the case shown in Figure 1,
Two samples were analyzed, and the reagent series was changed in both turns.
This is common to Daples (12-1) and (12-2).

- In the case shown in Figure 2, the rack 0-curvature is intermittently fed one sample container at a time, and both turntables (12-i) and (12-2) are set at an angle corresponding to one reaction tube. The rack is rotated intermittently in synchronization with the feed of the rack 0. During this time, the sample dispenser (16-1), (16
-2) from the sample container (+3) by turning the tape/
I/(12-1).

The same sample is sequentially dispensed into the reaction tube (11) placed on the tube (12-2). Then, the reaction tube into which the sample was dispensed (
During the test, reagents corresponding to the test items are dispensed from the reagent container (17) using the reagent dispensers (19-1') and (19-2). In the case shown in Fig. 2, only one sample is analyzed, and the number of test items is twice that of the case shown in Fig. 1. The time required is halved compared to when doing so.

In the case of Fig. 2, it is not possible to use the same reagent series for both turntables (12-1) and (12-2) (however, the reagent container group (e) is common). The reagent container group (e) may be configured in two rows as shown in FIG.

By configuring an automatic chemical analyzer as in the present invention, it is possible to appropriately select which of the number of test items or the number of samples to be processed should be given priority when conducting an analysis, and the analysis operation can be easily performed. Optimal high-speed processing can be performed without hindering efficiency.
