JP 2011-153942 A

  In order to manage the total discharge amount of laws and regulations substances contained in the waste liquid discharged from the automatic analyzer as disclosed in Patent Document 1, first, the number of purchases for each reagent or detergent in a certain period Assuming that the amount obtained by subtracting the number of stock from the amount used is the amount used, and using the concentration of the statutory substances obtained from the package inserts and product safety data sheets (MSDS), the emissions of the statutory substances are calculated for each reagent and detergent. Above, it is necessary to add up the total amount discharged from the device. However, since the legally relevant substances contained in the reagents and their concentrations differ for each reagent and detergent, the tabulation becomes complicated and prone to error. Further, since the amount used is not the amount actually used in the apparatus, it is difficult to accurately grasp the actual state of discharge.

  In addition, there are a plurality of reagents used for measurement with respect to components to be measured, and the types and concentrations of substances subject to laws and regulations differ for each type of reagent. When selecting a reagent, it is necessary for each reagent to have a function for predicting the discharge amount of the target substance for the set number of tests, but the automatic analyzer does not have a function for predicting the discharge amount.

  In addition, laws and regulations differ from country to country, and equipment users may want to manage emissions for specific substances even if they are not subject to laws and regulations in the country where the equipment is used. It is difficult to capture accurately.

  The typical present invention is as follows.

  In an automatic analyzer equipped with a sample probe for aspirating a sample and a reagent probe for aspirating a reagent, mixing the sample and the reagent, and analyzing the sample, the substance name of each legally relevant substance contained in each reagent and detergent, Total concentration of legally relevant substances from the amount of each reagent and detergent used, as well as a storage unit that stores the concentration of legally relevant substances contained in reagents and detergents, the relevant legal names of legally relevant substances, and legal control values for legally relevant substances It is an automatic analyzer provided with the calculation part which calculates quantity.

  Another aspect of the present invention is an automatic analyzer that includes a sample probe for aspirating a sample and a reagent probe for aspirating a reagent, mixes the sample and the reagent, and analyzes the sample, and is included in each reagent and detergent. An automatic analyzer includes a storage unit that stores a substance name and a concentration of a substance, and a calculation unit that calculates a total discharge amount of the substance from the usage amount of each reagent and detergent.

  Reduce the risk of counting errors when counting emissions of substances subject to laws and regulations discharged from equipment. Further, since the discharge amount is calculated based on the amount actually consumed, the discharge amount can be calculated accurately.

  Furthermore, by calculating and displaying the predicted emission amount of the legally relevant substance, it is possible to perform reagent comparison including not only the analysis performance and price but also the emission amount.

  In addition, even if the substance is not subject to laws and regulations, the device user can easily manage the emission amount for a specific substance.

  Embodiments of the present invention will be described below with reference to the drawings.

  The operation principle and basic operation of the automatic analyzer shown in this embodiment will be described with reference to FIG.

  Samples such as serum and urine in the sample container 25 are moved to the sample dispensing position by the rotation of the sample disk 1. At the sample dispensing position, the sample in the sample container 25 is sucked and discharged into the reaction container 4 by the dispensing operation of the sample pipettor 15 and the sample probe 27 connected to the sample sampling mechanism 2. The reaction container 4 from which the sample has been discharged is moved to the reagent dispensing position by the rotation of the reaction disk 3 while being kept at a constant temperature by the thermostatic chamber 9. At the reagent dispensing position, the reagent in the reagent container 6 installed on the reagent disk 5 is aspirated by the dispensing operation of the reagent pipettor 17 and the reagent probe 28 connected to the reagent sampling mechanism 7, and the sample has already entered. Is discharged into the reaction vessel 4. The reaction container 4 from which the reagent has been discharged is moved to the stirring position by the rotation of the reaction disk 3. At the stirring position, the sample and the reagent are stirred by the operation of the stirring mechanism 8 and the stirring rod 29. After that, every time the reaction vessel 4 crosses between the spectrophotometer 10 and the light source 26 due to the rotation of the reaction disk 3, the absorbance is measured at regular intervals, and is passed through the Log converter, A / D converter 18, and interface 23. Is taken into the microcomputer 19. The measured absorbance is converted into a concentration value, stored in the hard disk 22, and output from the printer 20 or displayed on the display 21. The first reagent barcode reader 31 and the second reagent barcode reader 30 read barcodes indicating reagent information and the like attached to the reagent container 6.

  In the apparatus configuration described above, the reaction vessel 4, the sample probe 27, the reagent probe 28, and the stirring rod 29 are automatically washed and used for repeated measurement. The cleaning method is shown below.

  When the measurement is completed, the reaction solution in the reaction vessel 4 is sucked by the suction nozzle 12 of the cleaning mechanism 11 and discharged outside the apparatus. The reaction container 4 that has been emptied is discharged by washing the reaction container cleaning liquid 13 from the detergent injection nozzle 14 of the cleaning mechanism 11. Further, the reaction container cleaning liquid in the reaction container 4 is sucked by the suction nozzle 12 of the cleaning mechanism 11 and discharged out of the apparatus. Next, after the cleaning water is discharged from the cleaning mechanism 11 to the reaction vessel 4 by the operation of the cleaning water pump 16, it is sucked by the suction nozzle 12 and discharged outside the apparatus. By repeating this washing with the washing water a plurality of times, the reaction vessel 4 is reused for the next analysis. On the other hand, after the sample probe 27 and the reagent probe 28 discharge the sample or reagent to the reaction container 4, the outer wall and inner wall of the probe are washed with washing water and reused for the next analysis. In addition, after stirring the sample and the reagent in the reaction vessel 4, the stirring rod 29 is reused for the next analysis after the outer wall of the stirring rod is washed with washing water.

  However, in some cases, it is known in advance that the cleaning is insufficient only by this ordinary method. In this case, a cleaning process can be added by setting carryover avoidance cleaning. For the reaction vessel 4, the reagent probe 28, and the stirring rod 29, the detergent installed on the reagent disk 5 is sucked with the reagent probe 28, discharged into the reaction vessel 4 after being washed in a normal manner, and reacted with the stirring rod 29. By stirring the detergent in the container 4, the reaction container 4, the reagent probe 28, and the stirring rod 29 are washed. About the sample probe 27, after washing | cleaning by a normal method, the sample probe 27 is wash | cleaned by attracting | sucking the detergent installed in the sample disk 1 with the sample probe 27, and discharging to the washing tank which is not shown in figure. The type of detergent used for cleaning, the amount of suction, and the number of times are arbitrarily set according to the type and degree of dirt.

  Next, the user uses the keyboard 24 to specify the names of the legal substances contained in each reagent and detergent, the concentration of the legal substances contained in each reagent and detergent, the applicable legal names of the legal substances, and legal requirements. A screen for entering a management value will be described. FIG. 2 is an example of a screen for inputting the substance name, concentration, applicable law name, and legal control value of the legally relevant substance. First, in the item selection area 32, an item registered in the apparatus is selected. Next, R1, R2, detergent and the like are input in the reagent type input area 33. Based on the description of the MSDS and the attached document, the substance name is input in the substance name input area 34 and the concentration is input in the concentration input area 35. Finally, the legal name corresponding to each substance is entered in the legal name input area 36 and the legal management value is entered in the legal management value input area 37. Legal control values are numerical values specified by laws and regulations. When a single substance falls under multiple laws and regulations, different numerical values may be set for each law.

  FIG. 3 is an example of a table that stores the substance name, concentration, applicable law name, and legal management value of the legally-regulated substance entered. The storage table stored in the hard disk 22 is divided into two, a totaling data storage table 38 and a screen display data storage table 39. The data input on the screen of FIG. 2 is registered in both the totaling data storage table 38 and the screen display data storage table 39. The tabulation data storage table 38 is a table for calculating the discharge amount, and the screen display data storage table 39 is a table for screen display.

  In the above input example, the user has shown the method of registering the substance name, concentration, applicable law name and legal control value of the substances subject to law contained in each reagent and detergent using the keyboard 24. You may download from external storage media, such as CD.

  FIG. 4 is an example of a table storing the substance name, concentration, applicable law name, and legal management value of the law-regulated substance downloaded. The information to be downloaded is divided into two types: total data (emission calculation data) and screen display data. The total data is stored in the total data storage table 38 and the screen display data is stored in the screen display data. Registered in table 39. For example, in the case of sodium azide, if it contains 0.1% or more, it is the first of the “Dangerous and Hazardous Substances to be notified of names, etc.” of the Occupational Safety and Health Act Corresponds to a species-designated chemical substance, and if contained in excess of 1%, it corresponds to a poisonous substance under the Poisonous and Deleterious Substances Control Law (poisonous and deleterious substances). If the MSDS or the package insert states “contains less than 0.1% sodium azide”, register the substance name “sodium azide” and the concentration “less than 0.1%” as data for screen display, and totalize As the data for use, an accurate numerical value of “0.05%” can be registered and used as a parameter for calculating the emission amount. In this way, substances subject to laws and regulations, but less than the regulated concentration, can also be included in the total emissions, even if they are subject to law, substances and concentrations not listed in the MSDS and package inserts. In addition, since the target substances and legal control values may be changed due to legal revisions, the latest information can be downloaded in the case of an automatic analyzer connected to a communication network. In the example of the table of FIG. 3, different densities can be stored in the tabulation data storage table 38 and the screen display data storage table 39 in the same manner.

  In this way, as the table (data) in FIGS. 3 and 4, the screen display table and the emission amount calculation table are provided, and both tables can store different concentrations for the same substance name. It is possible to distinguish and set the density parameter for display aligned with the document and the density parameter used for aggregation.

  Next, a screen for setting a management target value for each substance will be described. FIG. 5 is an example of a screen for setting a management target value. Enter the control target value for each substance in the control target value (single) setting area 40. Regarding the legal control value, the value registered in FIG. 3 or FIG. 4 is displayed, and when there are a plurality of legal control values for one substance, the smallest control value is displayed. Further, when managing as the total amount of a plurality of substances, in the management target value (total) setting area 41, the legal management value and the target management value are input for the total amount of the plurality of substances. Finally, the setting completion button 42 is selected, and the input content is stored in the hard disk 22. In the screen example of FIG. 5, only one target management value is shown, but a plurality of target management values may be provided.

Next, a method for calculating the total amount discharged from the apparatus for a certain legally relevant substance will be described. As shown in the description of FIG. 1, the reaction liquid in the reaction container 4 is sucked from the suction nozzle 12 and discharged outside the apparatus when the measurement is completed. In addition, the detergent is also used when carrying out the washing avoidance washing of the reaction vessel 4, the sample probe 27, the reagent probe 28, and the stirring rod 29, and is discharged outside the apparatus after washing. As described above, the reagent and the detergent installed in the apparatus are discharged after use, but the discharge amount depends on the number of specimens, measurement request information, and whether or not carryover avoidance cleaning is performed, and thus always varies. On the other hand, the amount of suction per operation (time) is determined for detergents and reagents, and the device monitors the number of dispensings in a certain period. Using the number of times of dispensing, the amount of suction, and the concentration information stored in the apparatus, the discharge amount EA (reagent 1) of the substance A derived from the reagent (1) is calculated by the equation (1).
EA (reagent 1) = CONCA (reagent 1) x VOLA (reagent 1) x NA (reagent 1) ... Formula (1)
EA (reagent 1) ... Amount of substance A released from reagent (1)
CONCA (reagent 1): Concentration of substance A contained in reagent (1)
VOLA (reagent 1) ... Aspiration volume of reagent (1) per one time
NA (reagent 1) ... number of aspirations of reagent (1) in a certain period Reagent (2), reagent (3) ... Reagent (n) may also contain substance A, so a certain period , The total discharge amount EA (reagent ALL) of the substance A derived from the reagent is calculated by the equation (2).

EA (Reagent ALL) ・ ・ ・ Total discharge amount of substance A derived from the reagent
CONCA (reagent i): Concentration of substance A contained in reagent (i)
VOLA (reagent i) ... Aspiration volume of reagent (i) per time
NA (reagent i)... The total discharge amount EA (detergent ALL) of the substance A derived from the detergent is calculated by the equation (3), as is the number of times of suction of the reagent (i) in a certain period.

EA (detergent ALL) ・ ・ ・ Total amount of substance A derived from detergent
CONCA (detergent i) ・ ・ ・ Concentration of substance A in detergent (i)
VOLA (detergent i) ・ ・ ・ Aspiration volume of detergent (i) per time
NA (detergent i): The number of times the detergent (i) is sucked in during a certain period. Therefore, the total discharge amount EA (ALL) of the substance A discharged from the apparatus is calculated by the equation (4).
EA (ALL) = EA (reagent ALL) + EA (detergent ALL) ... Formula (4)
Next, a screen for calculating the emission amount and displaying the result will be described. There are two methods for displaying the emission amount: a means for displaying using the law as a key and a means for displaying using the substance name as a key. FIG. 6 is an example of a screen that displays the emission amount using the law as a key. First, a law is selected in the means selection area 43. Next, a law is selected in the law selection area 44, and a start date and an end date are set in the totaling period designation area 45. Finally, by selecting the aggregation execution button 46, the apparatus starts automatic aggregation. In the input example in Fig. 6, the total amount discharged from the automatic analyzer between January 1, 2010 and December 31, 2010 for the substances corresponding to PRTR (Class 1 Designated Chemical Substances) was instructed. It is an example. When the calculation is completed, the substance name corresponding to the applicable substance name display area 47, the emission status for the legal control value and target control value set in Figure 5 in the emission level display area 48, and the emission amount in the emission display area 49 are displayed. The The result display example in Fig. 6 shows that among the substances discharged from the equipment, the substances corresponding to PRTR (Class 1 Designated Chemical Substance) are polyoxyethylene alkyl ether, triethylamine, sodium azide, and the total emission amount is It shows that they are 800kg, 1050kg and 300kg, respectively. Further, the total emission amount of triethylamine exceeds the legal control value, and the total emission amount of polyoxyethylene alkyl ether exceeds the management target value. The screen example in FIG. 6 shows a method of displaying with a mark so that the user can identify, but a method of displaying by color or notifying by a device alarm may be used. Any display method can be used as long as it can be identified by the user. There are three types of identification categories: less than the management target value, more than the management target value and less than the statutory management value, and more than the statutory management value.

  As shown in FIG. 6, the total period can be set in the total period designation area 45, and the storage unit stores the discharge amount of the corresponding substance for each period in the storage unit so that the total can be calculated in this period. . If it can be set in the aggregation period designation area in units of one day, the emission amount data is stored in the storage unit every day, and if it is in units of months, the emission amount data is stored in the storage unit for each month.

  FIG. 7 is an example of a screen that displays the emission amount using the substance name as a key. First, a substance is selected in the means selection area 42. Next, the substance whose emission amount is to be calculated is selected in the substance selection area 51, the start date and the end date are specified in the total period specifying area 45, and the total execution button 46 is selected. The input example of FIG. 7 is an example in which the total amount of triethylamine discharged from the automatic analyzer between January 1, 2010 and December 31, 2010 is totalized. The substance selected in the applicable law display area 52 is displayed with the name of the applicable law, the emission level display area 48 for the legal management value and the target management value set in FIG. The result display example in FIG. 7 shows that triethylamine falls under the Industrial Safety and Health Act and PRTR (Class 1 Designated Chemical Substances), and the total emission amount is 1050 kg. In addition, the total emission amount of triethylamine exceeds the legal control value, so it is displayed with a mark. In the example of the screen in FIG. 7, a method of displaying with a mark is shown, but a method of displaying by color or notifying by a device alarm may be used. The point described in FIG. 6 is not limited as long as it is a method that can be identified by the user, and the same applies to FIG. 7 in that the classification and data are stored in the storage unit.

  In the screen examples of FIGS. 6 and 7, the calculated total emissions are shown as numerical values, but when the monitor display button 50 in the screen examples of FIGS. 6 and 7 is selected, the transition of the total emissions is displayed in a graph. The

  FIG. 8 is an example of a screen showing the transition of the total emission amount in a graph. In the graph area 53, the total emission amount accumulated in units of months is plotted for the substances tabulated in FIG. 7, and the arrival status to the legal management value and the target management value is displayed. Select the law name in the law selection area 44 and the substance you want to display in the graph in the substance selection area 51, specify the start date and end date in the totaling period specification area 45, and select the execution button 54. It is also possible to redisplay in 53. In addition, FIG. 8 shows an example of a screen in units of months, but it may be displayed in units of days or years.

Next, an embodiment relating to the calculation of the predicted emission amount is shown below. FIG. 9 is an example of a screen for setting a condition for calculating a predicted emission amount of a target substance. In the condition setting area 55, item names and reagent names registered in the apparatus are displayed. In the selection area 56, the item for which the predicted emission amount is to be calculated is specified, and the number of tests used for the calculation is input in the test number input area 57. When the Ejection Prediction button 58 is selected, when the number of tests entered for the specified reagent is analyzed according to Equation (5), the estimated total emission amount of substance A discharged from the device is calculated, and the estimated emission amount is Is displayed.

EA '(ALL) ・ ・ ・ Total estimated amount of substance A derived from the reagent
CONCA (reagent i): Concentration of substance A contained in reagent (i)
VOLA (reagent i) ・ ・ ・ Aspiration volume per one test (reagent)
NA '(reagent i) ... number of aspirations of reagent (i) (number of entered tests)
There are two methods for displaying the predicted emission amount: a means for displaying using the law as a key and a means for displaying using the substance name as a key.

  FIG. 10 is an example of a screen that displays the predicted emission amount using the law as a key. When a law is selected in the law selection area 44, the corresponding substance name is displayed in the corresponding substance name display area 47, the emission status for the legal control value and the control target value set in FIG. The estimated discharge amount is displayed.

  FIG. 11 is an example of a screen that displays the predicted emission amount using the substance name as a key. When a law is selected in the substance selection area 51, the substance selected in the relevant law display area 52 is the name of the law, the emission status for the statutory management value and the management target value set in Figure 5 in the emission level display area 48, and the predicted emission amount A predicted discharge amount is displayed in the display area 60.

  As shown in FIGS. 9 to 11, the automatic analyzer of the present invention includes means for inputting the number of tests for each analysis item, and the calculation unit includes the legally relevant substance contained in the reagent corresponding to the target analysis item. It is possible to calculate the predicted emission amount of the statutory substances by calculating the sum of the product of the concentration of sucrose, the amount of suction per test (times) and the input number of tests. With this function, the user can easily obtain information necessary for management such as how many tests the management target value and legal control value will be reached in, and vice versa.

  Next, an example in which reagent comparison is performed from the viewpoint of predicted emission amount, analysis performance, and cost is shown below. FIG. 12 is a table that stores the emissions of legally relevant substances, analysis performance, and price scores. The information to be registered in the score storage table 61 includes at least item name, reagent name, and information on the discharge amount, analytical performance, and price of the legal target substance per test. Information related to analysis performance includes reproducibility, linearity, coexistence effects, and the like. Cost can be considered as information about the price. The score uses a qualitative value that can be compared. FIG. 12 shows an example using five qualitative values. The registration of the score may be input by the user using the keyboard 24, or information created by a third party may be downloaded from an external storage medium such as a communication network or a CD. As described above, the automatic analyzer can easily manage the evaluation information of the reagent by providing the table for storing the discharge amount of the legal target substance, the analysis performance, and the price score for each reagent.

  If the reagent comparison button 59 is selected after setting the conditions for the predicted discharge amount in FIG. 9, the reagent comparison screen in FIG. 13 is displayed. In FIG. 13, information registered in the score storage table 61 is displayed. In the graph display area 62, the score of each element is displayed in a graph. Comparison can also be made with a table display as shown in FIG. 12, but the graph display as shown in FIG. 13 is more preferable because it is easier to compare visually. Furthermore, as shown in the figure, it is more desirable to display two or more types of reagents in an overlapping manner in the graph display area 62. As described above, the automatic analyzer includes the screen for comparing scores among a plurality of reagents, so that the user can select the reagent to be used based on the information on the discharge amount of the target substance. This is because even if the analysis items are the same, there are differences in the amount of discharge depending on the reagent manufacturer.

  Each element is a button. For example, when the discharge amount button 63 is selected, reagent names are displayed in the score detail display area 64 in descending order of score. When there are a plurality of measuring reagents for a certain measurement item, the user can compare and evaluate not only the analysis performance and price but also the emission amount of the target substance of the law in addition to the evaluation item.

  The present invention has been described above. In the examples, explanations were made including the substances subject to laws and applicable laws and regulations, but as stated in the issue, the laws and regulations differ from country to country. You may want to control emissions for specific substances. Therefore, the automatic analyzer according to the present invention can be applied to the case of calculating the total discharge amount of a predetermined substance, not limited to the target substance. In this case, provided with a storage unit for storing the substance name and concentration of the substance contained in each reagent and detergent, and a calculation unit for calculating the total discharge amount of the substance from the usage amount of each reagent and detergent good. The calculation method of the total emission amount is as described in the present embodiment. The difference can be realized by omitting the explanation of the law and applying it to the apparatus because it is not necessary to input the name of the law. In addition, the legal management value need only be read as the management value.
