Abstract

PROBLEM TO BE SOLVED: To cope with fluctuation when a reagent container changes by performing the measurement of an accuracy control sample that is performed continuously after measuring a standard sample for all measurement items of a standard sample and storing the measurement result in a device. SOLUTION: Reagent bottle information of the side surface of a reagent bottle 12 being set to a reagent disk 9 is read by a bar code reader 14 and is stored in a computer 10. An operator inputs an accuracy control execution item, an accuracy control sample, a standard sample measurement item, a standard sample, and a measurement container to the computer 10. With the standard sample set on a sample disk 8, the computer 10 controls a device according to storage information, and a sample and a reagent are dispensed into a reaction container 4 for reaction and photometry. Then, with the accuracy control sample set on the sample disk 8, the computer 10 controls the device according to the storage information, and the sample and the reagent are dispensed into the reaction container 4 for reaction and spectrometry. This enables accuracy control even when a reagent bottle changes.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and a device for measuring a quality control sample in an automatic biochemical analyzer.

[0002]

2. Description of the Related Art In a conventional apparatus, particularly, measurement of a standard sample and measurement of a quality control sample are positioned as separate measurements, and a user has made each measurement request independently. In addition, the quality control measurement was performed for each item, and the measurement for each reagent container was not performed.

[0003]

During the period in which the automatic biochemical analyzer is used, calibration is usually performed using a standard sample at the start of one day's work, and one day is used to confirm the deviation of the measured value during the work. Measure the quality control sample several times. Usually, the first measurement of the quality control sample is performed immediately after the calibration, that is, immediately after the measurement of the standard sample, in order to confirm the value of the sample itself. However, no consideration is given to the measurement of the quality control sample after the measurement of the standard sample, which should be measured by the conventional apparatus, and the user needs to determine the type and setting of the quality control sample as well as the standard sample. A request for measurement of the position, target item, and the like must be made, which is complicated. In recent years, in automatic analyzers, models having a plurality of containers each having the same item are increasing. However, the measurement of the quality control sample corresponds to the item, and does not correspond to the change when the container is changed.

[0004]

In order to achieve the above-mentioned object, the present invention provides an apparatus for instructing a quality control sample, which is continuously measured after measuring a standard sample, to issue a measurement request for all items for which the standard sample is measured. And the measurement result is stored in the device.

(1) When a reagent bottle is set in the apparatus, a bar code label attached to the bottle indicates
Recognize serial numbers that distinguish items and bottles. When there are several types of reagents such as a first reagent and a second reagent in one item, when a plurality of types of reagents are set, which reagent bottles are combined into one set is registered and stored.

(2) The quality control screen displays a list of quality control measurement results for each combination of bottles. The operator registers a combination of bottles requiring precision control from the operation unit. Which quality control sample is required for each item is designated and stored in advance.

(3) When the rack on which the quality control sample is placed is loaded, or the quality control sample is set on the sample disk and the start is designated, the quality control measurement is executed based on the combination information of the reagent bottles and the quality control request information.

(4) Quality control As the measurement results, item codes, serial numbers, and measured values are stored for each combination of reagent bottles.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG.

This automatic analyzer comprises a sample dispensing mechanism 1, a reagent dispensing mechanism 2, a stirring mechanism for a sample and a reagent 3, a reaction disk 5 on which a reaction vessel 4 for reacting a sample and a reagent is set, and a reaction disk 5 in the reaction vessel. A photometer 6 for measuring absorbance 6, a reaction vessel washing mechanism 7, a sample disk 8 for setting a sample, a reagent disk 9 for setting a reagent,
It is composed of a computer 10 for controlling the whole. The sample is put in the sample cup 11 and set on the sample disk 8. The reagent is placed in a reagent bottle 12 and set on a reagent disk 9.

An operation example of the automatic analyzer will be briefly described. The sample disk 8 rotates and moves the sample container containing the sample to be analyzed to the position of the sample dispensing mechanism 1. After aspirating the sample, the sample dispensing mechanism 1 discharges a required amount into the reaction container 4. Thereafter, the reaction disk 8 rotates and stops at the position of the reagent dispensing mechanism 2, and a required amount of reagent is discharged into the reaction container 4 by the reagent dispensing mechanism 2. Thereafter, the reaction vessel 4 moves to the position of the stirring mechanism 3 and is stirred. The stirred reaction vessel 4 passes through the position of the photometer 6 and the absorbance is automatically measured, and the absorbance is converted into a concentration by the computer 10. After the analysis, the reaction vessel 4 is washed by the reaction vessel washing mechanism 7 and used for the next analysis.

Next, a method of performing the quality control measurement will be described.

(1) Registration of Reagents A plurality of reagent bottles 12 of the same item are set on the reagent disk 9. A bar code is attached to a side surface of the reagent bottle 12. The information contained in this barcode is the item name, reagent manufacturing lot number, expiration date of the reagent, and reagent bottle size. The information on the reagent bottle read by the barcode reader 14 and the position of the reagent bottle on the reagent disk are stored in the computer 10.

(2) Designation of Quality Control The operator uses the CRT screen 15, the keyboard 16 or the floppy disk 17 to specify an item for which quality control is to be performed and a quality control sample to be used for quality control.
The information is stored in the computer 10.

(3) Measurement of standard sample In the same manner as the quality control, the operator measures the standard sample, the standard sample, and, if the same item has a plurality of reagent containers, the CRT screen 15 and the keyboard 16
Alternatively, the program is stored in the computer 10 using the floppy disk 17. The operator puts the standard sample into the sample cup 11 and sets it on the sample disk 8.
When the start of the standard sample measurement is designated, the computer controls the apparatus in accordance with the stored information, dispenses the designated quality control sample and the reagent in the reagent bottle into the reaction vessel, causes the reagent to react, and performs photometry. When the measurement is specified for a plurality of reagent containers in the same item, the measurement is performed for all the containers. This measurement result and information on the measured reagent container are stored in the computer.

(4) Execution of Quality Control Measurement The operator puts the quality control sample into the sample cup 11 and sets it on the sample disk 8. When the start of quality control is specified, the computer controls the apparatus according to the stored information, dispenses the specified quality control sample and the reagent in the reagent bottle into the reaction vessel, causes the reagent to react, and performs photometry. When the measurement of the standard solution performed before the quality control measurement is performed for a plurality of reagent containers of the same item, the quality control measurement is performed for each of the reagent containers. The result is stored in the computer 10 for each reagent bottle together with the code number and serial number of the reagent bottle, and output to the CRT screen 15 or the printer 18.
