Definitions
- the present invention relates to an automated analyzer for performing qualitative / quantitative analysis of components in biological samples such as blood and urine, and a method for storing reagents in the automated analyzer.
- Patent Document 1 discloses an automatic analysis in which the first and second reagents and a sample are dispensed into a reaction vessel and the mixed solution is measured.
- the apparatus has a first reagent container, a second reagent container, a reagent rack, and a driving unit, and the first reagent container and the second reagent container contain the first and second reagents, respectively, and are connected to each other.
- each has a support that can be released, the reagent rack holds the first reagent container and the second reagent container, and allows the release of the support so that the first reagent container and the second reagent container are used for analysis.
- the driving unit moves the first reagent container and / or the second reagent container so that the support portions are connected to each other when the first reagent container and the second reagent container are taken out.
- An automated analyzer is a device that reacts a sample with an analytical reagent that specifically reacts with the component to be measured in the sample, and detects the complex produced by this reaction by a spectroscopic method such as electrochemical emission. It is possible to automatically perform everything from the detection of the component to be measured to the output of the result.
- Such an automated analyzer is one of the necessary devices for efficient analysis for laboratory centers and other medical research facilities that undertake sample inspection / testing for hospitals and clinics.
- automated analyzers are roughly classified into three types according to measurement items. First, it is a biochemical analyzer that measures components such as sugar, cholesterol, protein, and enzymes. Next, it is an electrolyte analyzer that measures electrolytes in blood such as sodium and potassium. Finally, it is an immunoanalyzer that measures components related to immune diseases such as cancer markers, thyroid hormones, and infectious disease markers.
- the above three devices have different measurement principles, that is, the sample-reagent reaction principle and the reaction complex detection principle. Therefore, the hardware components and functions are different, especially in the analysis section.
- the consumables used for the measurement for example, regarding the analytical reagent, as described in Patent Document 1, the reagent component and the amount of the reagent required for the analysis are different.
- each analyzer In order to cover all biochemical analysis, electrolyte analysis, and immunoanalysis, it is necessary to install each analyzer in the laboratory.
- Each device is equipped with all the mechanisms necessary for analysis and has a certain occupied area.
- This mechanism includes, for example, a sample dispensing mechanism, a reagent dispensing mechanism, a sample-reagent reaction mechanism, a detection mechanism, and the like.
- each device is integrated as a common mechanism rather than having a mechanism individually for common functions that do not depend on the measurement principle.
- One of the means is to share the analytical reagent storage.
- the analytical reagent storage refers not to the reagent storage area installed in the laboratory, but to the reagent storage area provided inside the apparatus.
- the amount of reagent required for analysis differs between various devices due to the difference in measurement principle, there are many cases where the capacity (size) of the reagent pack per pack differs between various devices. Further, even if the measurement principle is the same, the shape of the reagent pack may differ depending on the type of reagent.
- the reagent storage of the automatic analyzer is equipped with a reagent holding unit for storing reagent packs individually.
- the holding portion has a function of suppressing the shaking of the pack due to the vibration of the device, and is designed to fit the shape of the pack.
- the shapes of the reagent pack for biochemical analysis (hereinafter referred to as biochemical reagent pack) and the reagent pack for immunoanalysis (hereinafter referred to as immunoreagent pack) are different from each other, and they are stored in the same storage. If this is the case, it is necessary to install two types of reagent holders corresponding to each shape.
- the total number of reagent packs that can be stored on the device at one time is the same as the total number of corresponding dedicated holding units.
- the dedicated holding part of the biochemical reagent pack has 20 positions and the dedicated holding part of the immunoreagent pack has 20 positions, for a total of 40 positions.
- the user needs to handle the predetermined number of positions, that is, the biochemical reagent pack and the immunoreagent pack according to 20 positions each, for example, 30 biochemical reagent packs and 10 immunoreagent packs.
- the predetermined number of positions that is, the biochemical reagent pack and the immunoreagent pack according to 20 positions each, for example, 30 biochemical reagent packs and 10 immunoreagent packs.
- the present invention provides an automated analyzer and a method for storing reagents in an automated analyzer in which restrictions on the installation of reagent packs are smaller than those of a conventional apparatus.
- the present invention includes a plurality of means for solving the above problems.
- One example is an automatic analyzer that analyzes a sample using a reagent corresponding to a predetermined analysis item, and includes a reagent storage for storing a reagent pack containing the reagent, and the reagent storage.
- a first holding unit that can hold only the first reagent pack containing the first reagent among the reagents, and a second reagent pack containing a second reagent that is different from the first reagent. It is characterized by having a second holding portion that can only be held, and a third holding portion that can hold both the first reagent pack and the second reagent pack.
