摘要:
Accuracy control of an automatic analysis device that mixes a sample and a reagent to measure temporal change of a mixed solution is realized. A plurality of measurement point data is acquired from a reaction process of the sample and the reagent. Parameters and test values of approximate equations for approximating the plurality of measurement point data are accumulated in a storage unit. A distribution map of reference data corresponding to the parameters or the test values is created based on predetermined numbers of the parameters or the test values accumulated in the storage unit. Next, a plurality of screens for individually superimposing, on the distribution map, curved lines corresponding to a plurality of regression function candidates obtained by applying a plurality of regression functions are arranged and presented on a display screen, so as to approximate the data to the distribution map of the reference data.

Electrolyte analyzers are used in a variety of ways, and problems vary from reagent deterioration due to reagent replenishment, mixing of foreign substances during reagent replenishment, electrode deterioration due to the passage of the validity date, to the operator's inputting errors. It is thus necessary to judge abnormalities of measured values resulting from such inappropriate usage, based on the fluctuation patterns of the results of daily electrolyte calibration.The fluctuation patterns of each measured item are extracted from the results of daily electrolyte calibration. The electromotive force balance ratio between the internal standard solution and high/low-concentration standard solutions is calculated as well as its fluctuation pattern. The obtained fluctuation patterns are compared against atypical fluctuation patterns stored in the electrolyte analyzer. When any of the extracted patterns matches any of the atypical patterns, the analyzer activates an alarm.

An automatic analysis apparatus that is capable of aligning the timing of sample dispensing and efficiently carrying out tests of a plurality of items. An intermediate disk (disk) is set so that an A-cycle for carrying out an operation for pretreatment and B-cycles for carrying out operations for dispensing a sample to a reaction disk and a flow analysis mechanism serving as test mechanisms are combined to use n-units of the B-cycles as a dispensing operation cycle time period of the sample. Therefore, the timing of sampling can be efficiently aligned so that the test of an item having a short analysis cycle can be carried out during the test of an item having a long analysis cycle, and so that the tests of an item having a large number of requests can be carried out during the test of the item having a small number of requests.

An automatic analysis device 1a includes: an intermediate disk (intermediate unit) 20 on which a disposable container (intermediate container) 21 for carrying out a pretreatment by pretreatment liquid for a sample dispensed from a sample container 11 or a reaction with a reagent is arranged; a reaction disk (main analysis unit) 60 for carrying out a test of an item having a relatively large number of test requests, on which a reaction vessel 61 for carrying out a reaction of a reagent with the sample obtained after the pretreatment is arranged; and flow-based analysis mechanisms (sub analysis units) 30a to 30c for carrying out a test for the sample obtained after the reaction with the reagent in the disposable container 21, which is the item having a relatively small number of test requests.
摘要:
A plurality of analyzer units for serum, a plurality of analyzer units for blood plasma and a plurality of analyzer units for urine are arranged along a main transfer line for transferring a sample rack from a rack providing portion to a rack storage portion. A reagent bottle for inspecting liver function is contained in each reagent delivery mechanism of two analyzer units among the plurality of analyzer units for serum. When the reagent for inspecting liver function in one of the two analyzer units is to be short, analysis for the liver function analysis item to samples can be continued by transferring a sample rack from the rack providing portion to the other analyzer unit.
摘要:
The adverse effect on measurement accuracy brought about by the transmission of light beams through portions of a liquid sample with different concentrations, i.e., a concentration distribution in the vertical direction of a container, is prevented by using semiconductor light sources of two different types with different wavelengths. The semiconductor light sources (2, 4) of two different types are housed in the same package (5) such that a detector (9) can capture the light beams emitted by the light sources after their optical axes have intersected with one another. The multiple light beams can be thus caused to pass through portions with substantially the same concentration and therefore can be detected without being influenced by the difference in concentration of the sample in the container.
摘要:
An automated analyzer device has a main conveyance line capable of conveying a sample rack holding a sample, a plurality of analysis units arranged along the main conveyance line, a rack supplying device for supplying the sample rack to the main conveyance line and a rack housing device for housing the sample rack conveyed by the main conveyance line. The automated analyzer includes a controller for confirming that there is no sample rack on the main conveyance line before the main conveyance line receives the sample rack from the rack supplying device. The controller controls operation of the main conveyance line so as to convey the sample rack received from the rack supplying device by the main conveyance line to a position corresponding to a specific one of the plurality of analysis units by which the sample rack is to be received without stopping.

摘要:
An automatic analyzer has a plurality of analytical units to which analysis items are allocated. When necessity of execution of calibration or accuracy management occurs, a display block relating to an occurrence cause on a state inspection screen flickers. When a receiving button corresponding to the flickering display block is instructed, the related analysis item name and analytical unit name are displayed in the display area and calibration or accuracy management is executed.
摘要:
An automatic analyzer in which abnormalities of reagents and samples used are displayed. Abnormalities are displayed in the form of a list which is composed of an alarm colored display table and an alarm detailed table. With respect to the alarm colored display, alarms which have occurred in reagents, standard solutions and control analytes in each analytic item are displayed in the form of a list so as to be classified by colors. With respect to the alarm detailed table, analytic information concerning abnormality of reagent, abnormality of standard solution, abnormality of control analyte, number of analyses, term of validity, alarm, etc. and information concerning the kind of reagent, the kind of standard solution, the kind of control analyte, the setting position, etc. which will be newly required for analysis in the future now are displayed.
