In addition, the sampler 2 is provided with an information reading device 24 at a delivery position of the plurality of racks 8 to the transport device 11. The information reading device 24 reads information on the information recording medium attached to the rack 8 sent from the sampler 2 to the transport device 11, and outputs the read rack information to the central control device 10.

  Here, the rack 8 is formed with a plurality of recesses for holding the sample container 7 at a predetermined pitch along the longitudinal direction, and is transported by the transport device 11. The rack 8 is provided with an information recording medium as an identification index read by the information reading devices 24, 33, 48, 58, and 68 on the side surface and the end surface. In this information recording medium, rack information including the type of rack 8, the rack number, the analysis items of the sample held in each sample container 7 and the like is recorded.

  As an identification index provided on the rack 8, in addition to the bar code label, electromagnetic information can be written and erased, for example, a recording medium such as an IC tag, a notch or a color mark provided on the rack 8. Alternatively, at least one of the colors of the rack 8 itself or a combination thereof may be used. In this case, when an IC tag is used as an identification index, wireless communication means is used as a reading device, and when a notch or a color mark or the color of the rack 8 itself is used as an identification index, the reading device is a CCD camera or the like. Imaging means are used.

  In addition, the sample container 7 contains a specimen to be analyzed in advance, and an information recording medium on which analysis items and the like are recorded is attached. This information recording medium is read by the information reading devices 24, 33, 48, 58 and 68 in the same manner as the information recording medium attached to the rack 8. Here, the sample container 7 is a container for storing a specimen such as serum. However, the sample container 7 may contain a reagent alone, a liquid sample containing a mixed solution of the reagent and the specimen, or may be empty.

  The analysis units 3 to 6 are provided in parallel along the transport device 11 and operate under the control of the central control device 10. The analysis unit 3 is a unit that analyzes an electrolyte test item in a sample by an electrode method, and includes a sample dispensing mechanism 31, an information reading device 33, and a unit control unit.

  The sample dispensing mechanism 31 is configured to be rotatable and movable up and down, and sequentially sucks samples from a plurality of sample containers 7 held by the rack 8 on the overtaking line 12 or the transport line 13 and discharges them to the measurement container 32. To do. The specimen discharged into the measurement container 32 measures an electrolyte made of ions such as sodium, chlorine, potassium, calcium, inorganic phosphorus. The information reading device 33 is provided adjacent to the overtaking line 12 at a position facing the conveyance device 11, and the information recording medium pasted on the rack 8 conveyed to the analysis unit 3 by the overtaking line 12 or the conveyance line 13. Read the barcode. The information reading device 33 outputs the read rack information of the barcode to the central control device 10. The unit control unit 34 includes a CPU, a RAM, a ROM, and the like, and is a sub-control unit that controls the operation of the entire analysis unit 3 including the sample dispensing mechanism 31 in response to an instruction from the central control device 10. The unit controller 34 outputs measurement data including measurement items, measurement results, and the like in the analysis unit 3 to the central controller 10.

  The analysis units 4 to 6 analyze the biochemical test item, the analysis unit 5 analyzes the immunological test item, and the analysis unit 6 analyzes the genetic test item. 4, the analysis units 5 and 6 are denoted by reference numerals corresponding to the corresponding components.

  The analysis unit 4 includes a cuvette wheel 42, a first reagent table 44, a second reagent table 45, an information reading device 48, and a unit control unit 49, and optically measures a reaction solution obtained by reacting a sample and a reagent. . The photometric data is output to the unit controller 49, and the unit controller 49 quantifies the concentration of the specific component contained in the sample.

  In the cuvette wheel 42, a plurality of reaction vessels 43 are held in two rows at different radii along the circumferential direction, and a sample is dispensed into the reaction vessel 43 by the sample dispensing mechanism 41. The sample dispensing mechanism 41 is configured in the same manner as the sample dispensing mechanism 31, and sequentially sucks samples from a plurality of sample containers 7 held by the rack 8 on the overtaking line 12 or the transport line 13 and discharges them to the reaction container 43. To do. The first reagent table 44 holds a plurality of reagent bottles containing the first reagent, and a first reagent dispensing mechanism 46 is disposed in the vicinity thereof. The first reagent dispensing mechanism 46 dispenses the first reagent corresponding to the analysis item to the corresponding reaction container 43. The second reagent table 45 holds a plurality of reagent bottles containing the second reagent, and the second reagent dispensing mechanism 47 dispenses the second reagent corresponding to the analysis item to the corresponding reaction container 43.

  The information reader 48 reads the barcode of the information recording medium attached to the rack 8 that has been transported to the analysis unit 4 by the overtaking line 12 or the transport line 13. The information reading device 48 outputs the read rack information to the central control device 10. The unit control unit 49 is configured by a CPU, a RAM, a ROM, and the like, and is a sub-control unit that controls the operation of the entire analysis unit 4 in response to an instruction from the central control device 10. The unit control unit 49 outputs measurement data including the sample name, the measurement item of the sample, the measurement concentration, and the like to the central controller 10.

  Here, the analysis units 5 and 6 are required to have high analysis accuracy, and the carry-over of the specimen is strictly limited. Therefore, the transport of the rack 8 by the transport device 11 is controlled by the central control device 10 so that the analysis units 5 and 6 are preferentially executed prior to the analysis in the analysis units 3 and 4.

  In response to an instruction from the central controller 10, the transport control unit 9 distributes the rack 8 delivered from the rack supply unit 21 to the overtaking line 12 and the transport line 13, and returns the rack for which the analysis processing in the analysis unit 6 has been completed to the return line 14. And the operation of recovering the rack 8 transported through the return line 14 to the rack recovery unit 22 is controlled.

  The central control device 10 is a personal computer that controls the entire automatic analyzer 1, and includes a control unit 10a, a storage unit 10b, an input unit 10c, an output unit 10g, and an interface 10j, as shown in FIG. Are connected to each other to send and receive information.

  The control unit 10a is configured by a CPU, a RAM, a ROM, and the like, and controls the entire automatic analyzer 1. The control unit 10a determines the analysis unit that should transport the rack 8 based on the rack information (sample analysis item) sent from the information reading device 24, and instructs the transport device 11 to determine the analysis unit of the determined transport destination. To do. Further, the control unit 10a confirms whether or not the rack 8 is transported to the regular analysis unit designated based on the information of the information recording medium read by the information reading devices 33, 48, 58, and 68. When the rack 8 is transported to the wrong analysis unit from the information on the information recording medium read by the information readers 33, 48, 58, 68, the control unit 10 a instructs the transport device 11 to transfer the rack 8. . Here, the control unit 10a controls switching of connection or disconnection to the network 80 by the interface 10j. For example, when the selection unit 10d selects the analysis of the genetic test item, the automatic analysis device 1 is disconnected from the network 80. .

  The storage unit 10b stores, in addition to rack information read by the information reading devices 33, 48, 58, and 68, various kinds of information related to a preset password such as a password and analysis operation of the automatic analyzer 1.

  The input unit 10c is an operation unit that inputs various information including analysis items related to the analysis operation to the automatic analyzer 1, and for example, a keyboard or a mouse is used. The input unit 10c includes a selection unit 10d, an input request unit 10e, and a quality control instruction unit 10f, which are displayed in various modes such as tabs, dialog boxes, or selection buttons on the screen displayed on the display unit 10h. be able to.

  The selection unit 10d selects any one of genetic test items, biochemical test items, and immunological test items, in particular, a genetic test item or any other test item. At this time, for example, as illustrated in FIG. 2, the selection unit 10 d selects a genetic test item by double-clicking the genetic test from a screen W displayed on the display unit 10 h. When a genetic test item is selected in the selection unit 10d, the control unit 10a requests input of a preset password on the screen of the display unit 10h. When a correct password is input on the screen of the display unit 10h in response to this request, the input request unit 10e requests an input of approval for disconnecting the automatic analyzer 1 from the network 80, and automatically analyzes when the disconnection is approved. The device 1 is disconnected from the network 80. The quality control instruction unit 10f instructs the execution of quality control analysis for each inspection item.

  Here, in order to manage the analysis result of the sample with high accuracy, the automatic analyzer 1 monitors the analysis result by analyzing the same sample as the sample or a sample similar to the sample as the quality control sample. These operations are collectively called quality control. At this time, the analysis result obtained by the accuracy management is output as accuracy management information to the management device 90 via the network 80 and stored in the management device 90.

  The output unit 10g includes a display unit 10h and a warning unit 10i. The display unit 10h displays various information such as analysis contents, analysis results, alarms, tabs, dialog boxes, selection buttons, and the like related to the analysis operation in the automatic analyzer 1, and a display panel or the like is used. . At this time, the display content of the display unit 10h changes in parallel with the progress of the analysis work under the control of the control unit 10a. The warning unit 10i gives a warning by displaying on the display unit 10h that the automatic analyzer 1 is disconnected from the network 80 when analysis of the genetic test item is selected. In this case, the warning unit 10i issues a warning for disconnecting the automatic analyzer 1 from the network 80 prior to the approval of the disconnection in the input requesting unit 10e.

  The interface 10j is switching means that physically switches connection or disconnection of the automatic analyzer 1 to the network 80 in accordance with the examination item selected by the selection unit 10d under the control of the control unit 10a. A switch that is attached to the central control device 10 via a connector and switches between connection and disconnection to the network 80 by an actuator is used.

  The transport device 11 is a transport device using a belt conveyor that receives the instruction from the central control device 10 and transports the rack 8. The transport device 11 is arranged in parallel with each other along the arrangement direction of the analysis units 3 to 6, and an overtaking line 12 that selectively transports the rack 8 for emergency specimen or interrupt specimen to a specific analysis unit, and the rack 8. Are sequentially transferred to the analysis units 3 to 6, and a return line 14 for returning the rack 8 after being transferred to each analysis unit to the rack recovery unit 22. The overtaking line 12 and the conveying line 13 are intermittently operated to pitch the rack 8 to be positioned at the suction positions S3a, S3b to S6a, S6b of the analysis units 3 to 6 and stopped sequentially. If the transport device 11 has at least the transport line 13 and the return line 14, the overtaking line 12 is not always necessary.

  Further, the transport device 11 is provided with a line changer 15 across the overtaking line 12, the transport line 13, and the return line 14 on the downstream side of the rack 8 in the transport direction. The line changer 15 slides in the lateral direction perpendicular to the transport direction of the rack 8 to change the line that transports the rack 8.

  The automatic analyzer 1 configured as described above sets a plurality of racks 8 holding the sample containers 7 in the rack supply unit 21 of the sampler 2, and when the switch is turned on, under the control of the central controller 10, The rack 8 is sequentially sent out from the rack supply unit 21, and the rack 8 is transported to the analysis units 3 to 6 by the transport device 11. Then, after the sample in the sample container 8 is analyzed by the analysis unit at the transport destination, the automatic analyzer 1 is transported to the transport device 11, the rack 8 is returned to the sampler 2, and is recovered by the rack recovery unit 22. .

  Here, when the automatic analyzer 1 is started by turning on the switch, the initial screen shown in FIG. 2 is displayed on the display unit 10h. The operator selects a test item on the initial screen, and executes analysis of an electrolyte test item, a biochemical test item, an immunological test item, and a genetic test item. At this time, in the initial state in which the switch is turned on, in the automatic analyzer 1, the switch of the interface 10j is switched to the connection by the actuator and is connected to the management device 90 via the network 80. On the other hand, when the automatic analyzer 1 selects the analysis of the genetic test item, the switch of the interface 10j is switched to the disconnection by the actuator and is disconnected from the network 80. At this time, the genetic information management method of the present invention that leads to reconnection to the network 80 upon completion of the analysis of the genetic test item through the disconnection from the network by selecting the analysis of the genetic test item will be described below with reference to FIG. explain. FIG. 3 is a flowchart showing a gene information management method of the automatic analyzer when analysis of genetic test items is selected.

  First, the control unit 10a determines whether or not analysis of a genetic test item is selected based on information from the selection unit 10d (step S100). If analysis of the genetic test item is selected as a result of the determination (step S100, Yes), the control unit 10a requests input of a password (step S102). In this case, the control unit 10a causes the display unit 10h to display an input screen for password input that operates the analysis unit 6 that analyzes the genetic test item instead of the selection unit 10d. On the other hand, when the analysis of the genetic test item is not selected (step S100, No), the control unit 10a ends the gene information management of the automatic analyzer 1. In this case, since the analysis other than the genetic test item is selected, the control unit 10a maintains the connection of the automatic analyzer 1 to the network 80.

  Next, the control unit 10a determines whether or not a correct password is input on the input screen displayed on the display unit 10h (step S104). Whether the password is correct or not is determined by the control unit 10a reading a password stored in advance from the storage unit 10b and comparing the password with the input password. As a result of the determination, if the input password is incorrect (No at Step S104), the control unit 10a returns to Step S102 and requests input of the password again (Step S102). At this time, if the password is requested a plurality of times, or if the correct password is not entered within a predetermined time, the control unit 10a returns to the initial screen in consideration of the safety of information management and automatically analyzes The connection of the device 1 to the network 80 is maintained.

  On the other hand, when the correct password is input (step S104, Yes), the control unit 10a determines whether or not there is a request for accuracy management based on the information from the accuracy management instruction unit 10f (step S106). As a result of the determination, if there is a request for quality control (step S106, Yes), the control unit 10a instructs the quality control to the analysis unit 6 that analyzes the genetic test item (step S108). Based on this instruction, the analysis unit 6 executes quality management analysis and outputs quality management information from the network 80 to the management device 90. After instructing accuracy management, the control unit 10a proceeds to step S110.

  On the other hand, when there is no request for accuracy management (No in step S106), the control unit 10a warns of disconnection from the network 80 (step S110). This warning is made by displaying on the display unit 10h that the automatic analyzer 1 is disconnected from the network 80, and warning is given by voice or alarm sound from the warning unit 10i.

  Next, the control unit 10a determines whether or not the disconnection from the network 80 is approved based on the information from the input request unit 10e (step S112). Here, the approval of the disconnection is performed on the screen of the input request unit 10e displayed on the display unit 10h after displaying that the automatic analyzer 1 is disconnected from the network 80 on the display unit 10h. As a result of the determination, if disconnection from the network 80 is not approved (No at Step S112), the control unit 10a ends the gene information management of the automatic analyzer 1. In this case, since the situation is the same as when analysis other than the genetic test item is selected, the control unit 10a maintains the connection of the automatic analyzer 1 to the network 80.

  On the other hand, when disconnection from the network 80 is approved (Yes at Step S112), the control unit 10a instructs the switch of the interface 10j to disconnect from the network 80 (Step S114). As a result, the switch of the interface 10j is switched to disconnection by the actuator, and the automatic analyzer 1 is disconnected from the network 80. As a result, the automatic analysis apparatus 1 can analyze genetic test items in a state disconnected from the network 80, so that a third party cannot steal information from the outside through the network 80, and reliably leaks genetic information. Can be prevented. Thereafter, the control unit 10a instructs the analysis unit 6 to start analysis (step S116). Thereby, the automatic analyzer 1 starts the analysis of the genetic test item in the analysis unit 6 in a state where it is disconnected from the network 80.

  Next, the control unit 10a instructs the analysis unit 6 to end the analysis based on the analysis information including the analysis item and the like input from the input unit 10c (step S118). Thereby, the automatic analyzer 1 ends the analysis of the genetic test item by the analysis unit 6. Next, the control unit 10a determines whether or not a predetermined time has elapsed after the analysis end instruction (step S120). As a result of the determination, if the certain time has not elapsed (No at Step S120), the control unit 10a repeats Step S120 until the certain time has elapsed.

  On the other hand, when a predetermined time has elapsed after the analysis end instruction (step S120, Yes), the control unit 10a determines whether or not to continue the analysis of the genetic test items (step S122). Here, the control unit 10a resets the timer prior to the determination in step S122. The determination in step S122 is made on a screen asking whether to continue the analysis displayed on the display unit 10h. In this case, if the response to the screen asking whether to continue the analysis displayed on the display unit 10h is not within a predetermined time set in advance, the control unit 10a continues the analysis in consideration of the safety of information management. Judge that it is not.

  As a result of the determination, when the analysis of the genetic test item is continued (step S122, Yes), the control unit 10a instructs the analysis unit 6 to start the analysis (step S116). On the other hand, when the analysis of genetic test items is not continued (No at Step S122), the control unit 10a instructs the interface 10j to connect to the network 80 (Step S124). As a result, the automatic analyzer 1 is connected to the network 80. However, by providing a step for determining whether or not to continue the analysis of the genetic test item, even if the operator leaves the automatic analyzer 1, the third party can Inspection items cannot be analyzed, and the security of information management can be ensured.

  Thus, in the present invention, when analyzing a genetic test item, since the automatic analyzer 1 is disconnected from the network 80, a third party cannot steal information from the outside through the network 80, and the gene Information leakage can be surely prevented.

  Here, for the purpose of preventing leakage of genetic information, the automatic analyzer of the present invention and the gene information management method thereof, for example, the central control device due to an accident when the connector of the interface 10j is analyzed during analysis of genetic test items by the automatic analyzer 1 When the connector is disconnected from the network 10, even if the disconnected connector is connected to the interface 10 j, it is necessary to take measures to prevent the automatic analyzer 1 from being connected to the network 80 in the case of analysis of genetic test items. In this way, when the connector of the interface 10j is disconnected due to an accident, a procedure for reconnecting the connector to the interface 10j while maintaining the disconnected state from the network 80 will be described below with reference to FIG. FIG. 4 is a flowchart showing a procedure for reconnecting the connector disconnected during the analysis by the automatic analyzer 1 to the interface 10j.

  First, the control unit 10a determines whether or not the connector is disconnected based on information from the interface 10j (step S200). As a result of the determination, if the connector is disconnected (step S200, Yes), the control unit 10a instructs the display unit 10h to warn that the connector is disconnected (step S202). Thereby, for example, a warning that the connector of the interface 10j is disconnected is displayed on the display unit 10h. At this time, a voice or warning sound may be emitted from the warning unit 10i to warn to that effect. On the other hand, when the connector is not disconnected (No at Step S200), the control unit 10a returns to Step S200 and repeats the determination of whether or not the connector is disconnected.

  Next, based on the information from the input request unit 10e, the control unit 10a determines whether or not the automatic analyzer 1 has been disconnected from the network 80 as a situation before the connector is disconnected (step S204). As a result of the determination, if the automatic analyzer 1 is connected to the network 80 (No at Step S204), the control unit 10a approves the connection of the connector (Step S206). This approval is executed by displaying on the display unit 10h that the connection to the interface 10j of the disconnected connector is approved. The operator confirms this display and then connects the disconnected connector to the interface 10j.

  On the other hand, when the automatic analyzer 1 is disconnected from the network 80 (step S204, Yes), the control unit 10a displays the disconnection maintenance with the network 80 on the display unit 10h (step S208). Next, the control unit 10a approves connection of the connector (step S210). The operator confirms this display and then connects the disconnected connector to the interface 10j. Therefore, in the automatic analyzer 1, the disconnected connector is connected to the interface 10j while maintaining the disconnected state from the network 80.

(Modification)
Here, when performing accuracy management during analysis of genetic test items, the gene information management method of the present invention is as shown in FIG. FIG. 5 is a flowchart showing a gene information management method of the automatic analyzer when accuracy control is performed during analysis of genetic test items. The flowchart shown in FIG. 5 is different in that a step for instructing quality control is newly inserted between step S116 and step S118 of the flowchart shown in FIG.

  That is, when performing accuracy management during analysis of genetic test items, as shown in FIG. 5, the control unit 10a instructs the analysis unit 6 that performs analysis of genetic test items after instructing the start of analysis (step S116). Management is instructed (step S118). In this case, the analysis unit 6 periodically performs quality control analysis and outputs the obtained precision management information to the control unit 10a. Then, the control unit 10a connects the automatic analyzer 1 to the network 80 in real time or periodically, and transmits accuracy management information to the management device 90. At this time, if the analysis unit 6 is connected to the network 80, the analysis unit 6 interrupts the analysis of the genetic test item and prevents the leakage of the genetic information. Note that step S120 and subsequent steps instructing the analysis unit 6 to end the analysis are executed in the same manner as in FIG.

  As described above, according to the automatic analyzer and the gene information management method of the present invention, the analysis of genetic test items is performed with the automatic analyzer 1 disconnected from the network 80. Information cannot be stolen, and genetic information leakage can be reliably prevented.

  In addition to the above, as a method for selecting a test item, for example, a selection button can be set on the screen of the display unit 10h, or a genetic test item can be set in a pull-down menu. These inspection items may be set on the screen.
