Abstract

PROBLEM TO BE SOLVED: To provide an analyzer which can objectively evaluate the possibility of a data abnormality such as reagent deterioration and can continue a high- reliability analysis by comparing previous analysis data collected to a center with actual analysis data. SOLUTION: Before an analysis operation by the analyzer is carried out, a previous analysis data group is obtained from the center on the basis of an identification code of a set reagent bottle. The result statistically evaluated from the analysis data group when the analysis result is outputted is displayed and made a material for evaluating the reliability of the analysis result. Since the present analysis result can be evaluated with the analysis result collected from a wide region to the center and its evaluation being used as the material, the possibility of the data abnormality such as reagent deterioration can be evaluated objectively and the highly reliable analysis result can be obtained continuously.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a management method and management apparatus for analysis results related to a reagent solution used when analyzing an analysis item in an automatic chemical analysis apparatus, an automatic immunoassay apparatus or the like, and more particularly to a plurality of reagents. The present invention relates to a method and an apparatus for managing analysis results when handling a liquid. Generally, it is also applied to an analyzer that analyzes using a reagent.

[0002]

2. Description of the Related Art In the case of analyzing a biological sample, a reagent corresponding to an analysis item to be inspected in the sample is mixed with a sample to obtain a reaction solution, and an optical characteristic of the reaction solution is measured to analyze the analysis item. It is common to calculate the concentration of As a method of supplying the reagent liquid to the reaction container on the reaction line depending on the analysis item, there are a method using a pipettor using a reagent suction / discharge nozzle and a method using a dispenser using a reagent flow pipe. In either case, it is necessary to have a highly reliable analysis technique centered on reagents, such as prevention of reagent deterioration.

As an example of this, Japanese Patent Laid-Open No. 9-2642
No. 5 publication is known. This prior art describes a reagent management method that records and manages the identification code of a reagent bottle that has been used once, and detects and warns the reason for reagent deterioration such as the addition of deteriorated reagents. That is, the identification code of the used reagent bottle is stored in the memory, and its use is prohibited when the same bottle is set again in the reagent disk of the analyzer.

[0004]

According to the above-mentioned prior art, the number of analyzes that can be performed is managed for each reagent bottle, and the data abnormality is prevented due to the deterioration of the reagent that occurs due to the addition of reagents and the like. Higher analysis management is possible.

However, the reagent bottle management is not the only means for maintaining and supporting the high accuracy of the analyzer. For example, in a calibration in which a standard sample of known concentration is analyzed to create a calibration curve, if the result is inconvenient, the inconvenience may be propagated to a subsequent sample test using the calibration curve, which may hinder the accuracy of the analysis. . In addition, it is inconvenient to judge the analysis result of this control sample when the sample of known concentration (control sample) is analyzed at regular intervals in a series of sample tests and it is checked whether the value is within the correct variation range. If present, it may also hinder the accuracy of the analysis. Furthermore, in general sample analysis (including urgent samples), a specific reaction due to the specificity of the sample may occur (see Japanese Patent Application Laid-Open No. 6-213893). Accuracy may be impaired.

Conventionally, all of these have been judged by the person in charge of analysis based on the experience of the device in the facility. For example, in calibration, the correctness of the analysis is determined by how far it deviates from the previous calibration result, and the analysis result of the control sample is analyzed according to the degree of variation seen from the analysis result group of the control sample up to the previous time. Determine correctness. Regarding the specific reaction in the general sample, the reaction curve is visually observed, and the correctness is judged from the experience in the relevant laboratory up to that point. In any case, there was no choice but to rely on the subjective judgment of the inside of the examination room, and it was not possible to introduce objectivity and generality into the judgment.

An object of the present invention is to objectively check the possibility of data abnormality such as reagent deterioration by collating past analysis data collected from a plurality of analysis devices which may include analysis devices of other facilities with actual analysis data. The objective is to provide an analytical device that can be continuously evaluated to achieve highly reliable analysis.

[0008]

Means for Solving the Problems The present invention collects analysis result data from a plurality of analyzers in advance and distributes it to a judgment support center when a reagent corresponding to an analysis item is dispensed into a reaction container of the analyzer for analysis. The determination support information is stored in a state in which it can be acquired from the determination support center, and when the reagent solution tank is installed in the reagent installation section of the analyzer, the determination support information is acquired based on the identification information of the reagent, and the reagent The determination support information is used as a support material for the result determination in the analysis using the. Here, the analysis result data is preferably the absorbance value before concentration conversion, the concentration value, the parameters of the calibration curve for concentration conversion (for example, the slope of the calibration line), and qualitative determination information (true value). (False values, character strings and other means for describing the judgment), and the judgment support information includes the analysis result data itself or the processing information thereof (for example, statistical values such as average value and standard deviation value). Further, the device directly connected to the determination support center is not limited to the analysis device, but may be a terminal capable of inputting and outputting information equivalent to that of the analysis device, for example, a terminal equipped with a display and a setting device.

Further, by connecting a reagent provider or a device provider to the determination support center via a communication path, the determination support center can be provided with information such as reagent characteristics or device characteristics possessed by the provider. It is also conceivable that the configuration is used for the determination support information of the analyzer. In this case, on the contrary, the trader can obtain the usage status of the reagent or the device from the determination support center.

Furthermore, in order to allow the person in charge of analysis in the analysis device to receive the determination support, a configuration may be considered in which the past analysis record data existing in the determination support center is searched / extracted and browsed. In addition, by sending the question of the person in charge of analysis to the judgment support center, the person in charge of analysis of the vendor connected to the judgment support center or the person in charge of analysis of another analysis device is inquired and the answer is given to the questioner. It is also possible that the support center responds. In this case, the question and answer information can also be accumulated in the judgment support center and used as the judgment support information.

It is washed by 9 and reused. The stirring mechanism 13 mixes the sample added to the reaction container 6 and the reagent solution corresponding to the analysis item. A measurement signal based on the reaction solution obtained by the multi-wavelength spectroscope 15 is converted from an analog signal to a digital signal by the A / D converter 16 and input to the microcomputer 3.

On the reagent disk 26A for the first reagent and the reagent disk 26B for the second reagent, various reagent bottles 12 corresponding to respective analysis items are installed along the circumference. That is, the disks 26A and 26B are reagent bottle storage portions that can be selectively rotated. A barcode reading device 23A is provided near the disc 26A, and a barcode reading device 23B is provided near the disc 26B. The reagent dispenser includes reagent dispensing pipettors 8A and 8B and a reagent syringe pump 11. These pipettors 8A, 8B
Holds a predetermined amount of the reagent liquid in the reagent bottle 12 stopped at the suction position in the suction / discharge nozzles, rotates the suction / discharge nozzles above the reaction container row, and stops at the reagent receiving position. Then, the retained reagent solution is discharged. The reagent liquid dispensed at this time is of a type corresponding to the analysis item assigned to each reaction container.

As shown in FIG. 2, a reagent barcode label 22 having a barcode printed on its outer wall is attached to each reagent bottle 12. The information displayed as this bar code is, for example, a reagent bottle code unique to each bottle consisting of a sequence number, the size of the bottle, the expiration date of the reagent solution, the first reagent, the second reagent, or the third reagent.
It includes a reagent dispensing order indicating whether it is a reagent, the maximum number of times the reagent solution can be analyzed, a reagent dispensing amount indicating a single dispensing usage amount, a manufacturing lot number, and the like. The reagent information read by the barcode reading devices 23A and 23B from each reagent bottle 12 is
It is stored in the corresponding memory area of the storage unit 25 or the microcomputer 3. As the reagent bottle 12 is stored in the reagent discs 26A and 26B, the reagent information is read by the bar code reading devices 23A and 23B. At that time, the rotation angle detection unit provided in each reagent disc A signal indicating the set position of the reagent bottle is output and input to the microcomputer 3 via the interface 4. The reagent information, the bottle set position, and the analysis item are stored in association with each other.

The operator can input various information using the screen of the CRT 18 and the keyboard 21. The measurement result of the analysis item can be displayed on the printer 27 and the CRT 18. The information on the floppy (registered trademark) disk 24 is read by the reading device and stored in the storage unit 25 or the corresponding memory area of the microcomputer 3. The information stored on the floppy disk 24 is
For example: That is, it is an analysis item code displayed in 5 digits, parameters commonly used for the analysis item, parameters stored separately for each reagent bottle, and the like. Among them, the parameters commonly used in the analysis items are the wavelength used in the photometer, the sample amount,
Calibration method, standard solution concentration, number of standard solutions, limit value for analysis abnormality check, etc. The parameters for each reagent bottle include reagent type, reagent dispensing order, reagent bottle code, reagent liquid volume, reagent dispensing amount, maximum number of analyzable times, reagent manufacturing date, and the like.

In addition to the information read from, the operating conditions of each mechanism of the analyzer, the analysis parameters of each analysis item, the judgment logic for managing the bottle of each reagent, the maximum number of times analysis is possible from the reagent bottle, the analysis result, etc. Is memorized. The reagent information is provided by a floppy disk provided by the manufacturer when the reagent bottle is delivered. When the reagent information is not prepared by the floppy disk, the operator can input the information described on the visual confirmation sheet attached to the reagent bottle into the analyzer using the screen and the keyboard 21.

As shown in FIG. 3, the sample container 1 has a sample bar code label 50 having a bar code printed on the outer wall thereof.
Is pasted. The information displayed as the barcode is, for example, a sample identification number that uniquely determines the sample. This number is read by the barcode reading device 28, and the correspondence between the sample position and the sample identification number is recognized by detecting the angle of the sample transport disk 2. On the other hand, since the analysis item corresponding to the sample identification number is input and stored in advance by the keyboard 21 and the CRT 18, the sample position, the sample identification number, and the analysis item are eventually stored in association with each other when the barcode is read. In addition, it is generally possible to identify whether the sample is a standard sample, a control sample, or a general sample by the higher number of the sample identification number.

The analysis of the whole automatic analyzer is performed as follows by sampling, reagent dispensing, stirring, photometry, washing of reaction container,
It is carried out in the order of data processing such as concentration conversion. A plurality of sample containers 1 containing the sample are set on the sample disk 2. The sample disk 2 is controlled by the computer 3 via the interface 4. Further, in the sample disk 2, the barcode 50 on the outer wall of the sample container 1 is read by the barcode reading device 28, and the sample is associated with the analysis item. After that, in accordance with the order of the samples to be analyzed, the sample dispensing mechanism 5 is rotated and moved to a position below the probe, and the predetermined sample container 1
The sample pump 7 is connected to the sample dispensing mechanism 5
A predetermined amount is dispensed into the reaction container 6 by the operation of. The reaction container 6 into which the sample has been dispensed moves in the reaction bath 9 to the first reagent addition position. A predetermined amount of the reagent sucked from the reagent container 12 is added to the moved reaction container 6 by the operation of the reagent pump 11 connected to the suction / discharge nozzle of the reagent dispensing pipetter 8. After the addition of the first reagent, the reaction container 6 moves to the position of the stirring mechanism 13 and the first stirring is performed. When up to the fourth reagent is set in the reagent disks 26A and 26B, the addition-stirring of such reagents is
Performed for the fourth reagent.

The reaction vessel 6 in which the contents are agitated passes through the luminous flux emitted from the light source, and the absorbance at this time is the multiwavelength spectrometer 1.
5 is detected. The detected absorbance signal enters the computer 3 via the interface 4 via the A / D converter 16 and is converted into the concentration of the sample. The density-converted data is printed out from the printer 27 via the interface 4 and displayed on the screen of the CRT 18. After the photometry is completed, the reaction container 6 is moved to the position of the cleaning mechanism 19, is discharged from the inside by a container cleaning pump, is cleaned with a cleaning liquid, and is used for the next analysis.

One embodiment of the present invention is configured by connecting one or more of the above-described analyzers to a judgment support center via a communication path. FIG. 4 is a system block diagram of an embodiment of the present invention.

In FIG. 4, the analyzer 101A is connected to the communication unit 10 in the judgment support center 100 via the communication path 103.
Connected to 2. Similarly, a plurality of analyzers 101B,
101C etc. are connected. The operation of the analysis device will be described using the functional blocks in the analysis device 101A. When the reagent bottle is installed in the analyzer, the reagent bottle code is recognized by the reagent barcode reader. This bottle code is sent to the determination support center by the communication unit 104 for the purpose of requesting the determination support information. Instead of the recognition code of the reagent bottle, a code that identifies the reagent solution may be used for the request. No matter which code is used, the purpose is to request the judgment support information as the characteristic of the reagent liquid. In the judgment support center, a large number of analyzers (101A, 101B, 101 in this embodiment) have been used in the past.
The analysis result data sent by C) is stored in the storage unit 151. In response to a request from the analyzer, the determination support center uses the past analysis record data to calculate the average value and standard deviation of various analysis record data corresponding to the reagent liquid by the statistical unit 150. The calculation targets are the factor value of the standard sample, the concentration value of the control sample, and the absorbance at a specific point in the reaction process. Also, a specified number of absorbance series of all reaction steps are arbitrarily extracted. Further, the correctness determination and the text (non-numerical information) commented by the laboratory technician when the reagent solution is used in the past are also extracted. The calculated average value / standard deviation and the above-mentioned extracted information are sent back to the analyzer 101A that has made a request as determination support information. The analyzer 101A stores these as the factor memory 108 and the QC (Quali).
ty Control) value memory 109, reaction curve memory 10
7. Store in the comment memory 111.

When the analysis is started by the analyzer, the sample in the sample container 1 and the reagent are mixed in the reaction container 6 as described above, the reaction proceeds, and the absorbance signal output from the A / D converter 16 is When the sample is a general sample or a control sample, it is converted into a concentration value by the analysis result calculation 106. Also,
In the case of a standard sample, it is converted into a factor value corresponding to the slope of the calibration curve by the analysis result calculation 106. Next, the determination unit 1
15, when the sample is a standard sample, the average value and standard deviation of the factor values in the factor memory 108, and when the sample is a control sample, the average value and standard deviation of the concentration values in the QC value memory 109, and In the case of a general sample, the average value and the standard deviation of the absorbance at the specific reaction step in the reaction curve memory 107 are acquired. Using the acquired average value and standard deviation, and the determined value (converted concentration value or absorbance) in the analysis result calculation 106, the value obtained by dividing the difference between the determined value and the average value by the standard deviation is If the corresponding threshold value in the threshold memory 110 is exceeded, a warning is issued. Here, with respect to the information in the threshold memory 110, the threshold is set in advance for various judged values by the keyboard 21 and the CRT 18.

The generated warning is reported by a display on the CRT 18 or a buzzer for calling attention. Further, a warning is printed as incidental information of the analysis result printed on the printer 27. Further, a comment when the reagent is used in the past is displayed in the comment memory 111 to support the operator's judgment. In the comment, the past experience that the result cannot be judged as good and the reason thereof are written, so that the analysis result can be judged from various and objective viewpoints.

With these support, the person in charge of analysis reviews the results and solves the problem. If the user wants to leave the problem solving item for use in later determination support, he / she inputs a comment on the problem solving with the keyboard 21. If there is a comment, the determined value in the analysis result calculation 106 is stored in the storage unit 151 via the communication unit 104, the communication path 103, and the communication unit 102, and is used for later determination support.

When a standard sample or a control sample is provided by a reagent maker, a specific sample identification number is assigned to the sample and is clearly distinguished from the sample identification numbers of other general samples. When such a sample identification number is read by the sample barcode reading device 28, the determination unit 11
5, the sample identification number of the specific sample and the reagent code to be used are sent to the determination support center, and the determination support information is inquired. The determination support center extracts only the value when the particular sample is used among the factor values of the reagent, calculates the average value / standard deviation, and sends this to the analyzer. This makes it possible to support determination in consideration of the characteristics of the specific sample in addition to the characteristics of the reagent.

The determination support center is a reagent provider 160
A and 160B are also connected via a communication path. The reagent provider sets the reaction process absorbance series of the provided reagent and the reference average value / standard deviation of the provided standard sample / control sample as a sample via the communication channel. These set data can be used as judgment support information as described above by selecting the examination room. Further, it is also possible to similarly store the comment as the reagent provider regarding the specific reaction in the storage unit 151 of the determination support center and utilize it as the determination support information. Furthermore, the laboratory technician sends data and questions that are difficult to judge to the judgment support center, and the reagent provider receives this question, writes the answer / advice to this as a comment, and sends it to the judgment support center. The interrogator's analysis device receives it and the technician uses it to determine the test result. The address of the question is not limited to the reagent provider, and if the address of the question is to the technician of another facility, the knowledge of the technician of another facility can be obtained. The contents of these questions and answers are accumulated in the accumulation unit 151 as comments,
It can be used as later judgment support information.

The flow of information between the analyzer 101 and the judgment support center 100 will be described with reference to FIG. Analyzer 10
1 transmits the determination support information request 503. The determination support center 100 that has received this returns the determination support information 504 that is information that supports the evaluation of the analysis result. In addition, the analysis device sends the analysis result data 505 to the determination support center 100 after the analysis is completed. This analysis record data 50
5 includes some or all of the analysis result, the evaluation result of the analysis result, the name of the inspection engineer, and the facility name of the inspection facility, which is converted into determination support information by the determination support center. Further, in order to search a part or all of the analysis result data in the storage unit of the judgment support center, the analysis device sends an evaluation result search request 506 to the judgment support center, and in response to this, the judgment support center. Performs a search and returns the search result 507 to the analyzer.

FIG. 6 shows the data structure of the storage unit 151 managed by the judgment support center 100. The analysis result data transmitted from the analysis device 101 is stored in the storage device.
It is stored for each device ID which is the identification ID of 101. The management device number 601 indicates the number of analysis devices 101 managed by the determination support center 100. This portion 601 is called a header portion.

Device ID 602, device type 603, and PW
D604 and the number of data 605 indicate the ID for uniquely identifying the device, the model of the analyzer, the password, and the number of analysis record data managed. As the ID for uniquely identifying the device, the device unique number that can be read by the microcomputer of the device and is assigned for each manufacturing is used. However, when the address is uniquely determined when the device is network-connected. Can also use the address as the device ID. The password of the analysis device and the judgment support center of the other party who should be properly connected
It is a character string that only the person can know, and when the determination support center and the analysis device are connected, their passwords are collated on the communication path, and when they match, the communication connection is established only when they match. If they do not match, the communication is cut off because it is an incorrect analyzer or connection to the judgment support center. This prevents the risk of collecting wrong information of the analyzer and the intentional unauthorized connection.

The PWD 604 may further include an encryption key (public key system) for authenticating a person who transmits information by the analyzer and an operator at the determination support center. That is, in order to prove that the transmission content of a certain sender is indeed the sender, the hash value of the transmission content (by a method such as MD5) is encrypted with a secret key that only the sender can know. Attach the encrypted proof text to the transmission contents, and the receiving side will not recognize the sender's own transmission contents until the hash value of the transmission contents matches the value obtained by decrypting the above proof text with the sender's public key. You can confirm that there is. Since this encryption key can authenticate the person on both the analysis device side and the judgment support center side, it is possible to collect legitimate information while steadily confirming the mission and responsibility of being widely used as judgment support information. Such an authentication system can also be applied to communication between a trader and a determination support center, which will be described later. Further, if the incorrect analysis result data is transmitted due to an error, the responsibility can be fulfilled by requesting the decision support center to delete it when the error is found.

The above device ID 602 and device type 60
A data area composed of 3, PWD 604 and data number 605 is called a sub-header part.

FIG. 8 is a business flow chart of an embodiment of the present invention. Before starting the analysis, the operator of the analyzer sets the analysis parameter (801), the threshold (802), and the statistical inspection condition (803) as preparation for the determination support system to operate effectively. Analysis parameter setting (8
In 01), information is read from the floppy disk 24 and various parameters are fetched before the analysis operation by the analyzer is started. In the threshold value setting (802), a threshold value that is an upper limit index of the statistical bias is set for each reagent and for each standard sample and control sample.
