Abstract

The purpose of the present invention is to provide an automatic analysis device capable of efficiently performing a plurality of analyses, while reducing the footprint and cost of the device. Provided is an automatic analysis device characterized by being provided with containers for containing samples, one rack for placing the containers thereon, and a control unit, the control unit generating, with respect to the one rack, a plurality of registration patterns in which information of the positions where the containers are disposed, and information of the samples contained in the containers are correlated with each other, storing the registration patterns thus generated, applying, to the one rack, one registration pattern selected from among the registration patterns thus stored, and analyzing the samples. Also provided is an analysis method using the device.

First claim

The invention claimed is:

1. An automatic analysis device, comprising:
a reaction container;
a plurality of samples having different classifications;
a plurality of containers that contain a plurality of samples having different classifications;
one sample rack having a plurality of installation positions configured to hold the containers, the installation positions disposed at predetermined locations on the one sample rack;
a detection unit including a light source and an optical sensor configured to measure transmitted or scattered light from the sample in the reaction container;
a first dispensing probe; and
a control unit programmed to:
store a plurality of different registration patterns, each having a plurality of respective blocks to indicate arrangements of the containers to be held on the one sample rack,
receive, from an operator, respective first information for each of the blocks of each the plurality of registration patterns, the respective first information indicating a respective classification and a respective number of the installation positions which correspond to the respective classification for a respective one of the blocks,
automatically allocate, respective second information for each of the blocks of each of the plurality of registration patterns, the respective second information indicating a respective start position and a respective end position corresponding to the respective number of the installation positions in the respective first information for the respective one of the blocks,
receive, from the operator, a selection of one registration pattern from the plurality of registration patterns,
instruct the operator to install the containers at the installation positions of the one sample rack according to the first information and the second information of the selected registration pattern to apply the selected registration pattern to the one sample rack,
confirm, via input by the operator, that the selected registration pattern is applied to the one sample rack,
upon confirming the selected registration pattern has been applied to the one sample rack, control the dispensing probe to transfer one of the samples installed on the one sample rack to the reaction container, and
control the detection unit to analyze the sample in the reaction container,
wherein the registration patterns correspond to a plurality of types of methods for analyzing the sample including a calibration method, a first routine analysis method, and a second routine analysis method including biochemical analysis and blood coagulation analysis, and
wherein the different classifications include at least one of quality control samples, calibrators, pretreatment liquids, general samples, retest samples, factor deficient plasmas, cleaning solutions, and urgent samples.

2. The automatic analysis device according to claim 1 , further comprising:
a second dispensing probe,
wherein the control unit is programmed to:
control the second dispensing probe to transfer a reagent to the reaction container, and
control the detection unit to analyze a reaction solution of the sample and the reagent in the reaction container.

3. The automatic analysis device according to claim 1 , further comprising:
a display unit that displays information relating to an analysis of the sample,
wherein the control unit is programmed to control the display unit to display content of the selected registration pattern applied to the one sample rack together with a start button selectable to instruct the control unit to start the analysis of the sample.

4. The automatic analysis device according to claim 1 , further comprising:
a display unit that displays information relating to an analysis of the sample,
wherein the control unit is programmed to control the display unit to always display a plurality of buttons selectable to input the selection of the one registration pattern applied to the one sample rack or information of the selected registration pattern.

5. The automatic analysis device according to claim 1 ,
wherein the control unit is programmed to automatically allocate the respective start position and the respective end position so that the respective classification corresponds to the installation positions which are consecutive on the one sample rack.

6. The automatic analysis device according to claim 1 ,
wherein the installation positions of the one sample rack include a plurality of outer peripheral installation positions and a plurality of inner peripheral installation positions, and
wherein the control unit is programmed to prepare and store the registration patterns for each of the types of the methods for analyzing the sample so that the containers are respectively loaded at the outer peripheral installation positions and the inner peripheral installation positions.

7. The automatic analysis device according to claim 1 ,
wherein, for each of the registration patterns, the respective classification is different for each of the blocks.

8. The automatic analysis device according to claim 7 ,
wherein the control unit is programmed to automatically allocate the respective start position and the respective end position to define the installation positions which are consecutive from the respective start position to the respective end position on the one sample rack.

9. The automatic analysis device according to claim 1 ,
wherein the control unit is programmed to receive a schedule indicating an order for applying two or more of the registration patterns to the one sample rack.

10. The automatic analysis device according to claim 1 ,
wherein one of the classifications is urgent samples,
wherein the second information indicates the respective start position and the respective end position corresponding to the respective number of the installation positions for the respective block which corresponds to the urgent samples and which are separate from the other respective blocks for each of the registration patterns.

11. The automatic analysis device according to claim 1 ,
wherein one of the classifications is cleaning solutions and another one of the classifications is pretreatment liquids, and
wherein the second information indicates the respective start position and the respective end position corresponding to the respective number of the installation positions for the respective blocks which correspond to the cleaning solutions and the pretreatment liquids and which are separate from the other respective blocks for each of the registration patterns.

12. The automatic analysis device according to claim 4 , further comprising:
another reaction container,
wherein the control unit is programmed to:
when the selected registration pattern is changed to another one of the registration patterns, instruct the operator to install the containers at the installation positions of the one sample rack according to the first information and the second information of the other one of the registration patterns to apply the selected other one of the registration patterns to the one sample rack,
confirm whether the other one of the registration patterns is applied to the one sample rack, and
when the other one of the registration patterns has been applied to the one sample rack, control the dispensing probe to transfer another one of the samples to the other reaction container, and
control the detection unit to analyze the sample in the other reaction container.

13. The automatic analysis device according to claim 12 ,
wherein the control unit is programmed to, when one or more of the containers are absent at the corresponding installation pos
