Description

  The present invention relates to an analysis information management method and an analysis information management apparatus, and more particularly to an analysis information management method and an analysis information management apparatus suitable for automatically setting analysis parameters necessary for performing analysis in an analysis apparatus.

  An automatic analyzer is a device in which a sample and a reagent are placed in a reaction container and the contents of the sample are quantified by the chemical reaction. To use the automatic analyzer, the analysis parameters as analysis conditions are automatically analyzed. Therefore, it takes a lot of man-hours for the work. Here, the analysis parameter is a parameter for each test item in the automatic analyzer. Basically, the amount of sample dispensed, the reagent and amount used for analysis, the wavelength of absorbance to be measured, the type of reaction process, Consists of information such as concentration calculation method, standard sample used for calibration, and known concentration. These pieces of information relate to the reagents, and for example, even if the reagents are used for analyzing the same inspection item, they differ depending on the reagent manufacturer to be manufactured. Moreover, even if the reagents are manufactured by the same reagent manufacturer, if the manufacturing lots are different, the contents of the analysis parameters may be different. Therefore, the analysis parameter to be set must always be the latest analysis parameter related to the reagent set in the automatic analyzer.

  As a first method for setting an analysis parameter in an automatic analyzer, for example, as described in JP-A-11-211731, it is known that a user sets a parameter with a keyboard as an initial setting. Yes. As a second method, for example, as described in Japanese Patent Application Laid-Open No. 5-288756, a barcode for identifying a reagent affixed to a reagent container is read by a barcode reader and written on the barcode. It is known that various parameters are read from a computer using an identification code and set in an automatic analyzer.

JP-A-11-211731 JP-A-5-288756

  Here, in the parameter setting method described in Japanese Patent Application Laid-Open No. 11-211731, manual input from the keyboard requires a large amount of input man-hours, and more accurate parameter setting is performed due to an input error or the like. There was also a problem that there might not be. In particular, recent automatic analyzers tend to increase the number of parameters and the number of screens for setting them due to the sophistication of their functions. In some cases, a person in charge, such as a reagent provider, sets this parameter, then performs calibration or measurement of a quality control sample, confirms the operation, and provides it to the user. In this case, as a reagent provider, it is necessary to perform parameter setting work for all automatic analyzers of all inspection facilities that deliver the reagent. Therefore, as the number of automatic analyzers or inspection facilities and corresponding automatic analyzers increases, the number of man-hours for work increases.

  On the other hand, the parameter setting method described in Japanese Patent Application Laid-Open No. 5-288756 is a method in which parameter information is read from an external computer and automatically set using a bar code attached to the reagent container as a key. There was a problem that it was necessary to put a bar code on. In addition, after setting the analysis parameters, in order for the user to determine whether the setting has been performed correctly, specialized knowledge is required.

  An object of the present invention is to provide an analysis information management method and an analysis information management apparatus capable of easily setting analysis parameters of test items to be analyzed using a reagent.

  In order to achieve the above object, the present invention relates to a plurality of reagents used in a plurality of automatic analyzers used in a plurality of facilities, connected to a plurality of automatic analyzers used in a plurality of facilities through a communication line. A service center having a database for storing analysis parameters is provided, and analysis parameters of test items to be analyzed using a reagent are automatically transmitted via the communication line in response to a request from the automatic analyzer based on a request from an operator. An analysis information management method for transferring to an analyzer, wherein the service center requests a requested automatic analyzer from among reagent information stored in the database in response to a request from the automatic analyzer based on a request from an operator. A list of reagents that can be used is prepared and provided to the automatic analyzer via the communication line.

  This method makes it possible to easily set necessary analysis parameters even when the reagent container does not have a means for identifying a reagent such as a barcode.

In order to achieve the above object, the present invention provides a communication mechanism for transmitting / receiving information such as analysis information to / from each automatic analyzer, and information such as the analysis information. A database for storing information, an analysis information analysis mechanism for evaluating and analyzing results analyzed by the automatic analyzer using the analysis information stored in the database, and a reagent parameter registration mechanism for registering information about reagents in the database The communication mechanism is an analysis information management device that extracts analysis parameter information relating to reagents managed from the database and transfers them to the automatic analysis device in response to a request from the automatic analysis device based on a request from an operator. The service center receives information on the reagent stored in the database in response to a request from the automatic analyzer. Among them, create a list of reagents that can be used in the automatic analyzer requested, it is obtained so as to provide the automatic analyzer via the communication line.
With such a configuration, even when the reagent container does not have a means for identifying a reagent such as a barcode, a necessary analysis parameter can be easily set.

  According to the present invention, it is possible to easily set analysis parameters of inspection items to be analyzed using a reagent.

Hereinafter, an analysis information management method and an analysis information management apparatus according to an embodiment of the present invention will be described with reference to FIGS.
First, the configuration of an apparatus using the analysis information management method according to the present embodiment will be described with reference to FIG.
FIG. 1 is a block diagram showing a configuration of an analysis information management apparatus using an analysis information management method according to an embodiment of the present invention.

  All automatic analyzers 100A, 100B,..., 100Z of an inspection facility that concludes a service contract are connected to the service center 10 via a communication line L. One or a plurality of automatic analyzers 100 are installed in each inspection facility such that the automatic analyzers 100A and 100B are installed in the inspection facility 1 and the automatic analyzer 100Z is installed in the inspection facility M. In addition, a plurality of reagent providers 20A, 20B,..., 20N are connected to the service center 10 via a communication line L.

  The service center 10 centrally manages analysis information such as analysis parameters related to reagents and analysis results of each automatic analyzer. The service center 10 includes a communication mechanism 12, an analysis information analysis mechanism 14, a database 16, and a reagent parameter registration mechanism 18.

  The communication mechanism 12 transmits / receives analysis information to / from the automatic analyzer 100 connected via the communication line L. The analysis information analysis mechanism 14 evaluates and analyzes analysis information such as an analysis result sent from the connected automatic analyzer 100. The database 16 is connected to the automatic analyzer 100 via the communication line L, and all the reagents that can be used in all the automatic analyzers 100 that are in charge and the analysis parameters related to the reagents, the automatic analyzer 100 that is in charge. Analysis information, for example, information such as reagents and analysis parameters used at the time of analysis, calibration results, and analysis results of quality control samples is centrally managed. The reagent parameter registration mechanism 18 stores reagent information including the name of a test item to be analyzed using a reagent and a reagent lot number, analysis parameters related to the reagent, and information related to the reagent such as an automatic analyzer that can use the reagent. This is a mechanism for registering in the database 16.

  The reagent provider 20 is a supplier that supplies reagents to each facility. The reagent provider 20 is a reagent that can be used in all automatic analyzers 100 under the jurisdiction of the service center 10 and can create a new reagent that can analyze a new test item or a reagent for an existing test item. If the reagent production lot changes and it is necessary to add / update the analysis parameters related to the reagent and the reagent, the reagent parameter registration mechanism 18 makes a contract for registration in the database 16 of the service center 10 with the service center 10. It is tied between. As a result, the service center 10 holds the latest information regarding the reagent.

  In the automatic analyzer 100, it is necessary to set analysis parameters of test items to be analyzed using a reagent set in the automatic analyzer 100 before starting the analysis. When a new reagent newly delivered from the reagent provider 20 is set and used in the automatic analyzer 100, the corresponding analysis parameter may not be set in the automatic analyzer 100. In this case, the automatic analyzer 100 performs an operation of requesting the service center 10 to send a list that can list all reagents that can be used in the automatic analyzer 100 via the communication line L. The service center 10 searches the database 16, creates a list of reagents that can be used in the requested automatic analyzer 100 from the database 16, and transmits the list to the automatic analyzer 100 via the communication line L. The automatic analyzer 100 displays the received reagent list, and when the user selects a reagent set in the automatic analyzer 100, the selection information is transmitted to the service center 10. The service center 10 receives the selection information, searches for the corresponding analysis parameter, and transmits it to the automatic analyzer 100 via the communication line L. The automatic analyzer 100 sets the received analysis parameter.

  In the above-described example, the reagent list is transmitted to the automatic analyzer 100. However, the service center 10 has a home page where the reagent list is registered so that the automatic analyzer 100 can browse the reagent list. Is also good.

Next, the configuration of the automatic analyzer used in the analysis information management system according to the present embodiment will be described with reference to FIG.
FIG. 2 is an apparatus configuration diagram showing a configuration of an automatic analyzer used in the analysis information management system according to the embodiment of the present invention.

  A reaction vessel 112 is provided on the outer periphery of the reaction disk 110. The entire reaction disk 110 is held at a predetermined temperature by a heat insulating tank 114. The sample sample disk mechanism mechanism 120 is provided with a large number of sample cups 122. The sample in the sample cup 122 is appropriately extracted by the nozzle 128 of the sample pipetting mechanism 126 controlled by the sample dispensing mechanism 124 and injected into the reaction container 112 at the sample dispensing position.

  Reagent bottles with barcode labels are installed in the reagent disk mechanisms 130A and 130B. Bar code readers 132A and 132B are attached to each of the reagent disk mechanisms 130A and 130B, read the barcode at the time of reagent registration, and registers reagent bottle information corresponding to the position. The reagent bottle information includes information such as a reagent type, a lot number, an expiration date, and a reagent remaining amount.

  Each reagent disk is provided with a second reagent pipetting mechanism 142A and a first reagent pipetting mechanism 142B controlled by the reagent dispensing mechanism 140. The second reagent pipetting mechanism 142A pipettes the reagent from the reagent disk using the nozzle 144A and discharges it to the reaction vessel 112. The first reagent pipetting mechanism 142B pipettes the reagent from the reagent disk using the nozzle 144B and discharges it to the reaction vessel 112. Agitation mechanisms 146A and 146B are arranged in proximity to the reagent disk mechanisms 130A and 130B, and agitate the sample and the reagent in the reaction vessel 112. A reaction vessel 112 containing a photometric target is disposed between the analysis unit composed of the multi-wavelength photometer 150 and the light source 152. The cleaning mechanism 158 cleans the inside of the reaction vessel 112 with the cleaning liquid supplied from the cleaning water pump 156.

  Further, the control system and the signal processing system include a microcomputer 160, an interface 162, a log (logarithmic) converter 164, and an A / D converter 166. A printer 170 for printing, a CRT 172 for display, a hard disk 174 as a storage device, and an operation panel (keyboard or pointing device such as a touch screen or mouse) 176 for input. Further, a communication mechanism 180 for communicating with the service center 10 via the communication line L is provided.

  Next, the operation of the automatic analyzer 100 shown in FIG. 2 will be described.

  A predetermined amount of the sample placed in the sample cup 122 is dispensed into the reaction vessel 112 using the nozzle 128 of the sample pipetting mechanism 126 according to the analysis parameters stored in the memory in the microcomputer 160.

  Next, the reaction vessel 112 into which the sample has been dispensed is transferred to the reagent dispensing position by rotating the reaction disk 110. Thereafter, the reaction vessel 112 into which the sample has been dispensed using the nozzles 144A and 144B of the reagent pipetting mechanisms 142A and 142B according to the analysis parameters input from the operation panel 176 and stored in the microcomputer 160 is input. Dispense a predetermined amount into Thereafter, the sample and the reagent are stirred by the stirring mechanisms 146A and 146B and mixed.

  When the reaction vessel 112 crosses the photometric position, the absorbance is measured by the multiwavelength photometer 150. The photometric absorbance is taken into the microcomputer 160 via the Log conversion 164, A / D converter 166, and interface 162. This absorbance is converted into concentration data based on a calibration curve created from the absorbance of a standard sample solution measured in advance by an analysis method designated for each item. The measured component concentration data is output to the screen of the printer 170 or CRT 172. The measurement result may be transmitted to the outside via the communication mechanism 180.

  In the above measurement principle, the user performs various parameter settings necessary for measurement, sample registration, and confirmation of analysis results on the screen (CRT) 172.

  The reagent bottle may or may not be attached with a barcode on the side of the bottle. The reagent barcode includes reagent bottle identification information, reagent lot number, expiration date, and the like. As shown in FIG. 2, when the reagent barcode readers 132A and 132B are attached, for example, when the lids of the reagent disks 130A and 130B are closed, the barcodes of the reagent bottles at all the positions of the reagent disks are read. Reagent bottle information corresponding to the position is registered. On the other hand, when the barcode is not attached to the bottle, the user manually inputs the barcode information from the operation panel 176 and registers the reagent bottle information. The reagent bottle information includes information such as a reagent type, a lot number, an expiration date, and a reagent remaining amount. The test items that can be analyzed are determined by the reagents set in the reagent disks 130A and 130B, and analysis parameters that define the analysis conditions are required. Also, as an analysis parameter setting method, there are a method in which an inspection item is designated from the operation panel 176 and necessary parameters are manually input or read from an FD or a bar sheet.

Next, the contents of the analysis parameter setting process in the analysis information management method according to the present embodiment will be described with reference to FIGS.
First, the contents of the analysis parameter setting process according to the present embodiment will be described with reference to FIG.
FIG. 3 is a flowchart showing the contents of analysis parameter setting processing according to an embodiment of the present invention.

  Here, with reference to FIG. 3, processing contents from setting the reagent bottle to the reagent disks 130 </ b> A and 130 </ b> B of the automatic analyzer 100 to setting the corresponding analysis parameter will be described.

  In step s200, when the operator sets reagent bottles on the reagent disks 130A and 130B of the automatic analyzer 100 and closes the lids of the reagent disks 130A and 130B, for example, the microcomputer 160 of the automatic analyzer 100 displays the barcode reader. From 132A and 132B, the barcodes of the reagent bottles at all positions on the reagent disks 130A and 130B are read.

  In step s205, the microcomputer 160 retrieves the accumulated reagent bottle information and analysis parameter information from the read barcode information.

  Here, in the automatic analyzer 100, when the reagent screen is opened, for example, information on the reagent set at each position of the reagent disk as shown in FIG. 4 is displayed on the reagent information screen 172A of the CRT 172.

Here, an example of the reagent information screen in the present embodiment will be described with reference to FIG.
FIG. 4 is an explanatory diagram of a reagent information screen in the analysis parameter setting process according to an embodiment of the present invention.

  The reagent information screen 172A includes positions, inspection items, reagent types, reagent lot numbers. , Reagent bottle no. , Analysis parameter presence / absence, reagent information serial #, and the like. The position indicates the position where the reagent bottle is set in the reagent disk mechanisms 130A and 130B. 1, No. 1 A serial number is assigned as in FIG. In the illustrated example, the reagent set at position 1 has the inspection item name “ALP”, the reagent type “R1”, and the reagent lot No. Is “100001” and the reagent bottle no. Is “10001”, indicating that the analysis parameter is “present”. The reagent information serial # will be described later with reference to FIG. For example, the reagent at position “3” indicates that there is no analysis parameter. Position “4” includes position, inspection item, reagent type, reagent lot number. , Reagent bottle no. , Information such as the presence / absence of analysis parameters is not displayed at all. This is a case where a barcode is not pasted on the reagent bottle, and is displayed as a space.

  For example, when the barcode is not attached to the reagent bottle as in position 4, information that allows the operator to identify the reagent such as the reagent lot number by looking at the reagent bottle is displayed on the reagent information screen 172A. Enter in the space field.

  In step s210, the microcomputer 160 determines whether or not the reagent barcode information has been manually input on the reagent screen. If there is an input, the process proceeds to step s215, and if not, the process proceeds to step s220.

  As described above, if there is a manual input for the reagent at position “4”, in step s215, the microcomputer 160 searches the stored reagent bottle information, and if there is information on the reagent, displays that information on the reagent information screen 172A. To display. In addition, when the analysis parameter of the test item to be analyzed with the reagent is accumulated, “present” is displayed in the item of presence / absence of the analysis parameter. When a new reagent is set and there is no corresponding analysis parameter, no analysis parameter is displayed as in position 3 and it is necessary to set a new one before starting the analysis. In this case, the operator presses a “reagent list download button” at the lower right of the screen in the reagent information screen 172A shown in FIG.

  In step s220, the microcomputer 160 determines whether there is an instruction to download the reagent list. If there is an instruction, the process proceeds to step s225, and if not, the process proceeds to step s240. As described above, when the “reagent list download button” is pressed, it is determined that there is an instruction to download the reagent list, and the process proceeds to step s225.

  In step s225, the microcomputer 160 transmits a reagent list download request to the service center 10 via the communication line L. At this time, the microcomputer 160 also transmits identification information such as the model of the automatic analyzer 100 to the service center 10.

The service center 10 searches for all reagents that can be used in the automatic analyzer 100 that has requested the reagent list download, collects the reagents into a list, and transmits the list to the automatic analyzer 100 via the communication line L.
In step s230, the microcomputer 160 of the automatic analyzer 100 monitors the reagent list until the download of the reagent list is completed. When the download is completed, the reagent list shown in FIG. 5 is stored in the CRT 172 in step s235. Displayed as a list screen 172B.

  Here, an example of the reagent list screen in the present embodiment will be described with reference to FIG.

  FIG. 5 is an explanatory diagram of a reagent list screen in the analysis parameter setting process according to the embodiment of the present invention.

The reagent list screen 172B includes reagent information serial #, reagent manufacturer name, inspection item, reagent lot number. Etc. Reagent information serial # is a series of numbers for uniquely managing reagents. In the illustrated example, the reagent with serial number “20001” has the reagent manufacturer name “AAA”, the inspection item name “AST”, and the reagent lot No. Indicates “00001”. The operator looks at the reagent list and searches for a reagent for which an analysis parameter needs to be newly set, and inputs the inspection item name and the reagent information serial number in the corresponding position column of the reagent screen of FIG. For example, the reagent at position “4” shown in FIG. 4 is a reagent manufacturer “AAA”, an inspection item “AST”, and reagent lot No. When “00001” is “00001”, “AST” is input to the inspection item name of the position “4” in FIG. 4 and “2001” is input to the reagent information serial #. As a result, the reagent type and reagent lot No. Such information is also automatically entered. This process is performed for all reagents that need to be newly set without analysis parameters. When this process ends, the operator presses the “parameter download button” at the lower right of the reagent information screen 172A of FIG.
In step s240, the microcomputer 160 of the automatic analyzer 100 determines whether reagent information has been selected and whether there has been an instruction to download analysis parameters. If there is a selection or instruction, the process proceeds to step s245, and if not, the process proceeds to step s260.

  When there is an instruction to select reagent information or download analysis parameters, the microcomputer 160 creates an analysis parameter download request and transmits it to the service center 10 via the communication line L in step s245. The service center 10 searches for all analysis parameters requested to be downloaded and transmits them to the automatic analyzer 100.

  In step s250, the microcomputer 160 of the automatic analyzer 100 monitors until the requested analysis parameter download is completed, and when the download is completed, the received analysis parameter is accumulated in step s255. When the accumulation of the analysis parameters is completed, the analysis parameter is “Yes” in the corresponding position column of the reagent information screen 172A shown in FIG.

  In step s260, the microcomputer 160 determines whether or not the analysis start key has been pressed. When the analysis start key is pressed, the microcomputer 160 stores the analysis parameter in the memory of the microcomputer 160 at the start of analysis in step s265. Based on the analysis.

  In the above description, when a reagent barcode is attached to the reagent bottle, when the reagent screen is opened after reading the reagent barcode, the reagent bottle information and analysis parameters are searched by the barcode information, and the information is already Is stored, it is displayed as in position 1 or 2 in FIG. In addition, when the reagent set on the reagent disk is a new reagent, reagent bottle information is accumulated, and when there is a corresponding analysis parameter, the reagent bottle information is similarly displayed on the screen. If the relevant analysis parameter has not yet been accumulated, no analysis parameter is displayed as in position 3 in FIG. In this case as well, analysis parameters can be downloaded and set in the same manner as when no barcode is attached.

  In addition, if the reagent barcode contains information that can specify analysis parameters such as the name of the reagent manufacturer and the name of the test item, the user can automatically download a parameter list of the reagent so that the user can download the reagent list. The analysis parameters may be set without downloading and selecting the corresponding reagent information.

  Next, a method for verifying that analysis parameters are correctly set in the automatic analyzer will be described with reference to FIG.

  The automatic analyzer 100 performs analysis based on the analysis parameter set in step s265 of FIG. When an operator introduces a new reagent and newly sets an analysis parameter corresponding to the new reagent, the operator actually performs calibration to create a calibration curve, and then analyzes the quality control sample. The control unit 160 of the automatic analyzer 100 transmits the calibration result, the analysis result of the quality control sample, and the analysis information such as the reagents and analysis parameters used at that time to the service center 10 via the communication line L.

  When the service center 10 receives analysis information from each automatic analyzer 100 via the communication mechanism 12, the service center 10 classifies the received analysis information for each inspection facility or automatic analyzer, and stores and manages it in the database 16. The analysis information analysis mechanism 14 of the service center 10 takes out the analysis result of the quality control sample measured using the same reagent managed in the database 16, calculates the average value, and sets it as the standard value. And when it is determined that the analysis result of the quality control sample received this time was analyzed using the newly set analysis parameter, the deviation between the standard value obtained in advance and the analysis result received this time is obtained, It is determined whether it is within the allowable range. If this deviation deviates from the allowable range, for example, it is confirmed whether the correct analysis parameter is used for the reagent used in the analysis and whether the content of the set parameter is consistent. Then, a report summarizing these verification results and the countermeasures to be taken by the user is created and transmitted to the automatic analyzer 100.

  The operator of the automatic analyzer that has received the report starts inspection work based on the content of the report, for example, if there is no abnormality in the verification result, and takes action according to the content of the report if there is an abnormality.

As described above, analysis information such as the result information measured by the automatic analyzer is sent to the service center, and the result is analyzed and evaluated at the service center, so that the operation of the device can be verified from a global viewpoint. It is possible to assist the user of an automatic analyzer that does not have specialized knowledge so that it can be easily verified that the analysis parameters have been set correctly.
Each time the analysis information analysis mechanism 14 receives the analysis result of the quality control sample, it performs a deviation analysis with respect to the standard value. If there is an abnormality, the analysis information analysis mechanism 14 similarly sends the analysis result to the automatic analyzer 100 that has transmitted the analysis result. Send the analysis result as a report. If there is no abnormality, the analysis result is accumulated in the database 16, a report is periodically created and transmitted to the automatic analyzer 100.

  In the above description, the analysis of the deviation between the measurement result of the automatic analyzer 100 and the standard value in the whole is performed, and the analysis result is sent to the automatic analyzer 100 as a report. It is also possible to periodically obtain standard values of the automatic analyzer and periodically send the information as technical information to the automatic analyzer 100. By doing so, the operator of the automatic analyzer 100 can evaluate, for example, the measurement result of the quality control sample based on the technical information, and verify by himself that the newly set analysis parameter is being used correctly. It can also be done.

  In the above description, the database 16 of the service center 10 manages information related to analysis such as reagents, analysis parameters, and measurement results. However, the apparatus 16 is controlled for all automatic analyzers that have jurisdiction over that. The program may be stored for each version. Thus, for example, when a new reagent is introduced and an analysis method designated for each test item is added, and it is necessary to add or update a program for conversion to concentration data based on the analysis method, the analysis parameter As in the case of, it can be downloaded from the service center and automatically installed in the automatic analyzer. Furthermore, the database 16 of the service center 10 can manage version information of programs installed in the automatic analyzer that has jurisdiction, so it can accurately grasp the current state of the automatic analyzer that has jurisdiction. In addition, it is possible to respond to the program change as described above in a timely manner.

  As described above, according to the present embodiment, a bar that can identify a reagent in a reagent container even under the condition that there are a plurality of facilities using a plurality of reagent providing reagents, a plurality of automatic analyzers, and the like. Even when the code is not affixed, it is easy to set the analysis parameters of the test items to be analyzed using the reagent, and it is easy to verify that the analysis parameters have been set correctly Therefore, it is possible to improve the efficiency and reliability of the inspection work by the automatic analyzer. In addition, from the viewpoint of the reagent provider, it can be expected that the work related to the distribution of the analysis parameters to the inspection facility will be made more efficient.
