摘要： PURPOSE: To obtain an autoanalyzer which can deal with a detected abnormality quickly by a method wherein the detected abnormality of a sample and a reagent is displayed on a table so as to be related to an item to be analyzed. CONSTITUTION: An alarm color-coded display table 1-1 displays an alarm- generated item name in a part 1-3 so as to be displayed in red, yellow and violet according to an emergency level, an attention level and a warning level on an alarm level in relevant rows for a reagent, a standard solution and a control solution. When a plurality of abnormalities are generated in one item, an alarm whose importance degree is high is displayed preferentially, and an item which requires measures to be taken more urgently is displayed in a higher rank in the part 1-3 for the item name. An alarm detailed table 102 displays required information on the content and the measures in the table 1-1. For example, before and during an analytical operation, a display part 1-9 displays 'no residual quantity' regarding a reagent alarm in Item 2 in the table 1-1, and it displays 'reagent 1 not installed' regarding a reagent alarm in Item 20 on 'analysis required'. In this manner, the alarm generated item and the importance degree can be grasped easily, and an item to deal with can be recognized clearly from the table 1-2.

摘要： PURPOSE:To enable alarm display of expiration in use of the reaction container by registering analysis items of material and a reagent of the reaction container to control the frequency of washing operation and analysis items with a computer. CONSTITUTION:In a washing operation and analysis of reaction container 13, damages caused to individual reaction containers 13 are added up with a computer 8 by a scoring system. Likewise, the damages as caused by a maintenance operation are added up aside from the routine analysis. When the total value of the damages exceeds a certain value pertaining to individual reaction containers 13, an alarm display is performed. As a result, effects of the repetition of the washing operation and reagents of the analysis items cause damages to the reaction containers 13. An alarm is displayed for the expiration in the use of the reaction containers 13 from an automatic analyzer before the analysis results are affected thereby enabling the obtaining of more correct data.

摘要： PURPOSE:To prevent the contamination of vessels and flow passages only by water washing by optically measuring the progression degrees of the reaction of samples and reaction reagents and dispensing the reagent intended for washing the vessels and the flow passages by using a reaction vessel dispensing mechanism prior to discarding of the reaction soln. CONSTITUTION:The amt. of the samples, the dispensing amt. of the reagent and the wavelength for measurement are respectively specified. For example, serum is dispensed as the sample 1 and the reagent for testing thymol turbidity as a 1st reagent 6 into the reaction vessel 3. The sample and the reagent are stirred to effect reaction. The absorbance of the reaction liquid is measured by a photometer 8 in 5 minutes after the start of the reaction. An aq. 2N potassium hydroxide soln. is then dispensed as a 2nd reagent into the reaction vessel and is stirred to effect reaction. The reaction vessel is washed with water upon lapse of the prescribed time and is subjected to the ensuing measurement. The measurement error occurring in the contamination of the reaction vessel and the flow passage is prevented in such a manner without adding fresh devices thereto.

摘要： PURPOSE:To reduce a processing time with a higher operating speed of dilution containers along with a higher measuring accuracy and reproducibility, by providing a thermostatic tank which maintains the dilution container set on a disk at a specified temperature to keep temperature conditions of a sample. CONSTITUTION:This measuring apparatus is made up of a flow type electrode 3 kept at a specified temperature with an electrode thermostatic tank 22, a shipper syringe 19 for sucking sample to the electrode 3, a disk 10 having a plurality of dilution container 1 set thereon, a sampling mechanism 4 which injects sample into the containers 1, dilution liquid discharging mechanism for diluting samples in the containers 1 and the like. Then, the thermostatic tank 2 is provided to keep the container 1 set on the disk 10 at a specified temperature. Then before the sample diluted with the electrode 3 and an internal reference liquid are sucked up, the electrode 3 and solution are the same in the temperature to keep an electromotive force from the electrode 3 constant thereby achieving a higher accuracy and reproducibility. The constant temperature of the solution eliminates the need for waiting until the temperature becomes constant after the suction of the solution with the shipper syringe 19 thereby enabling a reduction in the processing time per sample.

摘要： PROBLEM TO BE SOLVED: To quickly detect an abnormality, to specify the cause of the abnormality, to quickly deal with the abnormality and to take measures, when abnormalities are generated in an autoanalyzer.
SOLUTION: All photometric points of a reaction process extinction and the extinction of an arbitray photometric point in the normal operation of the autoanalyzer for a ample for accuracy control, whose concentration is already known and in various abnormal operations or an extinction difference or a change amount, which is calculated for each photometric point and irregularities in the extinction are registered, in advance. When a specimen is measured, they are compared with the reaction process extinction of the sample for accuracy control which is measured periodically or arbitrarily so as to be determined. Whether the autoanalyzer is normal or abnormal is determined. When the autoanalyzer is abnormal, it is controlled, in such a way that an abnormal place is specified on the basis of the pattern of the reaction process extinction comforming in its comparison and determination and that the content of a defect, and a method of taking measures are displayed on a screen.
