A sample-processing system that improves total system processing efficiency, and reduces a sample-processing time, by establishing a functionally independent relationship between a rack conveyance block with rack supply, conveyance, and recovery functions, and a processing block with sample preprocessing, analysis, and other functions. A buffer unit with random accessibility to multiple racks standing by for processing is combined with each of multiple processing units to form a pair, and the system is constructed to load and unload racks into and from the buffer unit through the rack conveyance block so that one unprocessed rack is loaded into the buffer unit and then upon completion of process steps up to automatic retesting, unloaded from the buffer unit. Functional dependence between any processing unit and a conveyance unit is thus eliminated.

Automatic analyzer and sample-processing system

An automatic analyzer includes a storage unit for storing operation information information about usage histories of expendable supplies provided for the analysis, and an analysis-ID control unit giving an ID to the analysis, the analysis ID being used as information for identifying the analysis to derive a calibration curve. Data stored in the storage unit is organized along the same time axis both in the order of samples subjected to the analysis and inspection, and in the order of analysis items, so that the data is output in a total data display area. The data is organized from the viewpoint of an analysis process of an analysis item of each sample. By use of information used to identify an influence range based on a kind of an abnormal state, which is stored beforehand, a judgment is made as to whether or not it is necessary to perform reinspection.

Automatic analyzer

An automatic analyzer is provided that can promptly process a request for additional test items for a sample being analyzed or an error that has occurred in the sample. The automatic analyzer can output measurements of a sample analyzed, determine whether or not re-analyzing is necessary, and perform the re-analyzing. The automatic analyzer includes a buffer area for standby until analysis is completed and measurements are outputted. Each of analysis units includes a pair of buffer units that can randomly access the buffer area. The automatic analyzer further includes a position disposed near the buffer area, at which a sample can be unloaded and reloaded. A rack that stands by within the buffer area can be unloaded onto the unloading position by a command to unload issued by an operator. Subsequent reloading of the sample allows samples other than the sample in question to be analyzed continuously.

A method for an automatic analyzer to reduce a user's workload required when a reagent is placed therein, and thereby facilitating change of the operation mode of the automatic analyzer. The automatic analyzer including a first reagent storing unit that is capable of storing a plurality of reagent cassettes and a second reagent storing unit that is capable of storing a plurality of reagent cassettes. When the first reagent storing unit does not have empty space for a required reagent, and all reagents required for analysis operation for a selected operation set cannot be completely transferred to the first reagent storing unit, keeping the required reagent waiting in the second reagent storing unit. Further, when the first reagent storing unit is provided with empty space, the required reagent is transferred to the first reagent storing unit.

Automatic analyzer and method for using the same

In a sample-processing system that includes one or more function modules and one or more buffer units each combined as a pair with one of the function modules, in case of device stoppage due to failure, since a number of sample racks are held in the buffers, resetting involves a huge amount of time for storage of the racks. In addition, if the system configuration includes a plurality of buffer units, the resetting time increases with the number of buffer units. Sample rack ID reading means is provided in each buffer unit and during resetting, IDs of the sample racks in the buffer unit are read in the buffer unit. The buffer unit then uses the read information to make an inquiry to a control unit as to transport destinations of each sample rack. After this, sample processing based on transport destination instructions from the control unit is restarted using the buffer unit as a restarting position.

An automatic analyzer includes a function in which the measured data of a quality control sample is compared with reference maximum and minimum values of measured data of the quality control sample. When the measured data is out of the range between the reference maximum and minimum values, re-measurement for calibration is recommended to a user who can easily confirm the recommendation on an operation screen and request the re-measurement.

When a problematic reagent is identified while operating an automatic analyzer, it is required to have a plurality of screens displayed, and it is difficult for inexperienced operators to identify a problematic position of a reagent. With the present invention, control information for reagents and a calibrator required for analysis with an automatic analyzer are displayed concurrently, so that all necessary information can be referred to one screen. In the automatic analyzer according to the present invention, screen switching as required in the conventional technology is not necessary, and improved operability and visibility are provided.

The invention provides an automatic analyzer suitable for efficient reagent management. The analyzer allows continued use of existing reagent information storage media because reagent ID information that is no longer needed is overwritten so that it is unrecognizable to any analyzer. The invention relates to a method for automatically analyzing particular properties of an analyte by putting the analyte and a reagent into a vessel and measuring the reacted analyte-reagent mixture. The analyzer of the invention comprises: an information reader/writer for reading or writing regent information to/from storage media attached to reagent vessels; means for managing reagent information read from the storage media; means for processing reagents based on the managed information; and means for overwriting reagent information that has been judged unnecessary based on the managed information so that the unnecessary information is unrecognizable to any analyzer.

A specimen rack and a specimen carrier system includes a luminous body disposed on a vicinity of a specimen container loading slot to notify, to an operator, information concerning an analyzing situation and condition of the specimen contained in the specimen container held by the specimen rack.

An analysis device allowing any person to utilize job guidance for setting and assignment operations with high efficiency regardless of a level of skill in an automatic analysis device which has a complicated screen configuration with an increase of functions. A storage unit stores a job guidance file and a correspondence list file indicating correspondences between procedure IDs, codes, buttons, etc. in the job guidance file and screen IDs for device control program software. When an operator selects the procedure ID or the like in a displayed job guidance window, control is performed such that the screen ID corresponding to the selected procedure ID or the like is searched for in the correspondence list file, and the displayed screen is shifted to one corresponding to the searched screen ID for the device control program software.

ISE analytical unit for clinical analyzer

A reagent cassette used in an automatic analyzer for a clinical examination room, which provides an analysis environment enabling an operator to select reagent bottles with proper capacities depending on the number of tests to be performed in each different type of facility and to properly set reagents with ease. In the automatic analyzer comprising a sample pipetting section, a reagent pipetting section, a reaction cuvette, etc., one component in a sample is analyzed by using the reagent cassette in which one or a plurality of reagent bottles containing two or more types of reagents are combined together. The reagent cassette is provided with a reagent identifier including information regarding the presence or absence of a reagent opening of the reagent bottle for each of a plurality of positions of the openings.
