- control unit 114 sets the empty cycle of the second reagent dispensing mechanism 109, which is generated by stopping the operation of the first reagent dispensing mechanism 108 in step S703, as the next carry-in possible cycle (step S705). ..
- control unit 114 determines whether or not the delivery reservation of all the reagents has been completed (step S706). When it is determined that the reservation has been completed, the process proceeds to step S707, and when it is determined that the reservation has not been completed, the process returns to step S703.
- control unit 114 completes the reservation of the autoloader mechanism, the reagent disk 104, and each dispensing mechanism (step S707), waits for the passage of time, and executes the loading operation at the reserved timing (step S708).
- the remaining time can be displayed on the portion of the display unit 114a indicating the device state, and if there is a reagent management screen, it is possible to individually display how many minutes each reagent will be delivered.
- the display of the time until the completion of delivery is not limited to the display unit 114a on which the screen for operating the entire device is displayed, such as a small display installed in the device and an LED that informs the operator of the situation by the lighting state.
- Various display devices can be used.
- the control unit 114 create a carry-out plan for taking out the reagent.
- the method of making a carry-out plan and the carry-out procedure for carrying out the reagent container 120 from the reagent disk 104 are different in that the operation of the autoloader mechanism is opposite to that at the time of carry-in, and the carried-out reagent container 120 is installed on the reagent tray 107. , Basically the same way of thinking can be done. This point is the same in each of the following examples. Although the same reagent tray 107 is used for loading and unloading, the trays may be separated for loading and unloading.
- the above-mentioned automatic analyzer 101 of the first embodiment of the present invention includes a storage unit for storing consumables used for measuring a sample, a reagent gripping mechanism 110 for transporting the consumables, a reagent transporting mechanism 111, and a reagent gripping mechanism.
- a control unit 114 for creating and operating an operation plan of each device in the automatic analyzer 101 including the 110 and the reagent transfer mechanism 111 is provided, and the control unit 114 includes the reagent grasping mechanism 110 and the reagent transfer during sample analysis.
- the mechanism 111 When transporting consumables by the mechanism 111, the operation of the device that accesses the storage unit is stopped, and the reagent is gripped so that the consumables are also transported at the timing when the operation of the device that inevitably occurs after the stop is stopped.
- the operation of the mechanism 110 and the reagent transfer mechanism 111 is planned.
- n is a natural number of 1 or more
- the upper limit is the number of reagent containers 120 that can be stored in the reagent disk 104.
- the interruption cycle of sample dispensing required for carrying in n reagent containers 120 is (n + 1) cycle, and in this embodiment, two reagent containers 120 are carried in. It is possible to suppress the sample dispensing that is interrupted to 3 cycles. That is, the same number of reagent containers 120 can be carried into the apparatus, which is n-1 cycle less than that of the prior art. Therefore, it is possible to suppress the occurrence of useless free cycles that occur when a plurality of consumables are replaced during analysis as compared with the conventional case, and it is possible to suppress a decrease in analysis throughput as compared with the conventional case.
- control unit 114 when a plurality of consumables are requested to be carried in at one time, it takes longer than before to finish carrying in the final reagent. Moreover, since the measurement work is performed as usual except for the short time during which the product is carried in, it may be difficult to determine whether the replacement has been completed or is in progress by looking at the device.
- the display unit 114a for displaying the state of the automatic analyzer 101 is further provided, and the control unit 114 displays on the display unit 114a the time required to complete the transportation of all the consumables requested by the operator. Since it is clear that the instructed replacement work will be performed as instructed, the operator can rest assured that he / she can concentrate on other work and plan the next work based on the prospect of completion. .. Therefore, the efficiency of the operator's analysis work can be improved.
- a storage unit it has a reagent disk 104 for storing a reagent used for analysis, and a reagent tray 107 for placing a reagent carried in the reagent disk 104 or a reagent carried out from the reagent disk 104, and gripping the reagent.
- the mechanism 110 and the reagent transfer mechanism 111 transfer the reagent to either the reagent disk 104 or the reagent tray 107, and the device that accesses the reagent disk 104 is the first reagent component that dispenses R1 among the reagents. It has a dispensing mechanism 108 and a second reagent dispensing mechanism 109 that dispenses R2.
- the control of the present invention to the autoloader mechanism that automatically carries in and out the reagent container 120 instead of the operator, the effect of suppressing a decrease in analysis throughput while reducing the burden on the operator. Can be greatly obtained.
- first reagent dispensing mechanism 108 and the second reagent dispensing mechanism 109 can access the reagent disk 104 at the same time, and the control unit 114 carries in or out one reagent to the reagent disk 104 during the analysis. Therefore, the planning of the dispensing operation of the first reagent dispensing mechanism 108 and the second reagent dispensing mechanism 109 is stopped, and the second reagent component inevitably occurs after the cancellation of the operation plan of the first reagent dispensing mechanism 108.
- Other reagents are carried in or out of the reagent disk 104 at the timing when the operation of the mechanism 109 is stopped.
- FIG. 10 is a flowchart of mechanism reservation when an arbitrary number of reagent containers are carried in the automatic analyzer of the second embodiment.
- the automatic analyzer of this embodiment interrupts the transfer control of loading or unloading the reagent container 120 under analysis described in Example 1 and the loading instruction from the operator at that time, and interrupts all the analysis. It is possible to switch between transfer control in which reagents are carried in and out continuously, and the operator can instruct the device which transfer control should be executed.
- the transfer control in which the analysis is interrupted at that time and the plurality of reagent containers 120 are transferred during the analysis causes a decrease in the throughput of the analysis as compared with the transfer control using the inevitable stop timing as in the first embodiment.
- it has the advantage that the time from the start of delivery to the end is short.
- control unit 114 plans to carry in or carry out reagents using the inevitably occurring stop timing described in the first embodiment, and to continuously carry in or carry out all the reagents instructed by the operator. It is desirable to use them properly.
- Examples of the selection means include a dedicated selection button installed on the device, a selection screen displayed on the display unit 114a, and a method of switching with a toggle switch.
- a selection button a transport method using a stop timing that inevitably occurs when pressed briefly, and a transport method that continuously carries in or out all reagents instructed by the operator when pressed for a long time shall be implemented. Can be done.
- the method of selecting by pressing the button has been described, the selection may be made by how many times the button is pressed. Alternatively, two types of buttons may be prepared and selected according to the pressed button.
- the transfer control can be automatically switched according to the necessity of the reagent in the reagent container 120 instructed to be carried in by the control unit 114.
- step S801 when the control unit 114 first receives the carry-in request (step S801), the reagent transport control using the stop timing that inevitably occurs and the carry-in of all the reagents instructed by the operator or It is determined which of the transport control for continuous unloading should be used (step S801). When it is determined that the continuous transfer control should be executed, the process proceeds to step S802, the control unit 114 interrupts the sample dispensing in the next cycle, and summarizes the operation reservation of the autoloader mechanism for the number of reserved reagents. (Step S802).
- control unit 114 reserves a mechanism for stopping the second reagent dispensing mechanism 109 in a cycle in which the second reagent dispensing mechanism 109 cannot operate due to interference with the autoloader mechanism (step S803), and interferes with the autoloader mechanism.
- a mechanism reservation for stopping the first reagent dispensing mechanism 108 is made (step S804), and the process proceeds to step S810.
- step S801 when it is determined in step S801 that the transfer control should be executed one by one as in the first embodiment, the process proceeds to step S805. Since steps S805 to S811 are substantially the same as steps S702 to S708 shown in FIG. 9, details will be omitted.
- the automatic analyzer of Example 2 of the present invention also has almost the same effect as the automatic analyzer of Example 1 described above.
- control unit 114 determines the throughput by properly using a plan for loading or unloading reagents using the inevitably occurring stop timing and a plan for continuously loading or unloading all reagents instructed by the operator. Since the transfer control can be appropriately switched between the case where the decrease is desired to be suppressed and the case where the transfer does not take time, it becomes possible to flexibly respond to various situations.
- FIG. 11 is a flowchart of mechanism reservation when an arbitrary number of reagent containers are carried in the automatic analyzer of the third embodiment.
- FIG. 12 is a diagram showing a scheduling method of the reagent dispensing mechanism. Note that FIG. 12 is an example and changes depending on the operating status of the device.
- Example 1 was a control for intentionally creating a cycle for carrying in the reagent container 120. In this case, it may take up to 5 minutes from the sample dispensing to the dispensing of R2, so that the time from the operator's request for delivery to the completion of delivery of the reagent container 120 is completed. It takes up to 10 minutes for 5 reagent containers 120.
- the timing at which the second reagent dispensing mechanism 109 has a continuous empty cycle equal to or greater than the number of cycles required to carry in the reagent container 120 is determined.
- the sample dispensing can be interrupted so as to stop the first reagent dispensing mechanism 108, and the carry-in operation can be performed.

It is judged whether or not it exists in the inside, and if there is free time, the reagent is carried in or out during the free time, and if there is no free time, the first reagent dispensing mechanism It is assumed that the dispensing operation of 108 and the second reagent dispensing mechanism 109 is stopped so that the reagent is carried in or out.
- step S900 when the control unit 114 receives the carry-in request (step S900), the operation cycle 1002 of the final second reagent dispensing mechanism 109 currently planned as shown in FIG. 12 is reached. In the meantime, it is searched for whether or not there is an empty cycle 1001 capable of continuously carrying in all the requested reagent containers 120 (step S901). When it is determined that there are continuous empty cycles 1001, the process proceeds to step S910 to create and execute a transport plan for continuously carrying in all the reagents described in Example 2 (steps S910 to S915). ).
- step S902 the control unit 114 determines whether or not there are as many single-shot natural empty cycles that originally exist as the number of transport requests, without relying on the method described in the first embodiment or the like (step S902). When it is determined that there are as many empty cycles that can be transported as the number of all the requested reagent containers 120, the process proceeds to step S904, and a delivery plan for all reagents is created and executed (steps S904 to S915). ).
- step S903 when it is determined that there are as many empty cycles that can be transported as the number of all reagent containers 120, the process proceeds to step S903, and when the reagent containers 120 are carried in in the naturally occurring empty cycle.
- a carry-in plan for carrying in the remaining reagent container 120 as in the first embodiment is created and executed (steps S903 to S915) by utilizing the empty cycle generated in.

- control unit 114 when the control unit 114 is requested to carry in or carry out the reagent to the reagent disk 104, whether or not there is a free time in the reagent dispensing plan that is longer than the time required for carrying in or out of the reagent. If there is free time, the reagent is carried in or out during the free time, and if there is no free time, the first reagent dispensing mechanism 108 and the second reagent dispensing mechanism By stopping the dispensing operation of 109 and carrying in or out of the reagent, the number of sample dispensings interrupted only for transport, that is, the number of analysis interruptions, can be further suppressed, and the throughput reduction can be more effective. It can be suppressed.
- FIG. 13 is a diagram showing a scheduling method of the reagent dispensing mechanism in the automatic analyzer of the fourth embodiment.
- Each of the above-mentioned examples was in the form of dispensing two types of reagents using the first reagent dispensing mechanism 108 and the second reagent dispensing mechanism 109.
- test items in the automatic analyzer actually used in the clinical field include a third reagent (hereinafter referred to as R3) in addition to the test item using only R1 and R2 as in Example 1.
- R3 a third reagent
- a delivery plan of the reagent container 120 under analysis when an item using three types of reagents R1 to R3 is planned will be described.
- the case where the first reagent dispensing mechanism 108 performs R1 dispensing and the second reagent dispensing mechanism 109 performs R2 and R3 dispensing is given as an example.
- the flow chart of the mechanism reservation is the same as that of the first embodiment.
- FIG. 13 is just an example of a scheduling method when analyzing test items using three types of reagents, and such scheduling is not performed in all cases.
- the control unit 114 interrupts the sample dispensing in the cycle 1103, which is the sample dispensing immediately after, as shown in FIG. 13, as in the first embodiment.
- the suspension of sample dispensing in this cycle 1103 causes a stop cycle 1104 of the first reagent dispensing mechanism 108, and also a stop cycle 1105 of R2 dispensing by the second reagent dispensing mechanism 109 and a second reagent dispensing mechanism 109.
- R2 dispensing stop cycle 1106 is also generated.
- the empty carry-in cycle of the reagent container 120 occurs twice, the cycle 1105 for R2 dispensing and the cycle 1106 for R3 dispensing.
- cycle 1105 is the timing at which the second reagent can be carried in without intentionally interrupting the dispensing of the sample or discontinuing the R1 dispensing.
- the delivery of the reagent container 120 in cycle 1106 requires interruption of the first reagent dispensing mechanism 108.
- the R1 reagent dispensing and the sample dispensing are interrupted by the same procedure as in Example 1.
- the automatic analyzer of Example 4 of the present invention also has almost the same effect as the automatic analyzer of Example 1 described above. Further, according to this embodiment, even when a test item using three kinds of reagents is planned, a decrease in throughput can be suppressed.
- the case where there are two reagent dispensing mechanisms is mentioned, but the number of dispensing mechanisms is not particularly limited and may be any number. Further, the two reagent dispensing mechanisms may be used in any way, such as performing R1 and R2 dispensing by the first reagent dispensing mechanism 108 and R3 dispensing by the second reagent dispensing mechanism 109. The method of using the vacant one at the timing of reagent dispensing may be used.
- Example 5 The automatic analyzer of Example 5 of the present invention will be described with reference to FIG.
- FIG. 14 is a time chart diagram in the case where the reagent container is carried in and out as a set, as illustrated in the fifth embodiment.
- Example 1 the scheduling in the case where only the reagent is carried in or out is described.
- the free time equal to or longer than the time required for carrying out and carrying in the reagent exists in the reagent dispensing plan. Determine if you are doing it. Then, when there is free time, the reagents are continuously carried in and out during the free time. On the other hand, when there is no free time, the dispensing operation of the first reagent dispensing mechanism 108 and the second reagent dispensing mechanism 109 is stopped to carry in the reagent, and then carry out the reagent. And.
- the dispensing operation of the first reagent dispensing mechanism 108 and the second reagent dispensing mechanism 109 is stopped and the reagent is carried in. Let them carry out later.
- the carry-out and carry-in of the reagent are requested when the analysis is not performed, it is desirable to carry out the carry-out and carry-in of the reagent continuously. For example, when no analysis is performed, the device is in a standby state, or the device is not performing a sample and reagent dispensing operation and is waiting for an analysis request.
- control unit 114 puts the reagent container 120 carried in by the autoloader mechanism into the reagent disk 104 in cycle 2, and then raises the reagent gripping mechanism 110 on the spot. Make it wait at.
- the shutter installed in the charging port 105 is closed, and the reagent container 120 to be carried out by rotating the reagent disk 104 is moved to the position of the charging port 105.
- the reagent gripping mechanism 110 is lowered, the reagent container 120 is taken out from the reagent disk 104, and the reagent container 120 taken out by moving the reagent transfer mechanism 111 is moved to the reagent tray 107.
- the automatic analyzer of Example 5 of the present invention also has almost the same effect as the automatic analyzer of Example 1 described above.
- control unit 114 when the control unit 114 is requested to carry out and carry out the reagent from the reagent disk 104, whether or not there is a free time in the reagent dispensing plan that is longer than the time required for carrying out and carrying in the reagent. If there is free time, the reagents are continuously carried in and out during the free time, and if there is no free time, the first reagent dispensing mechanism 108 and the second reagent are continuously carried out. By stopping the dispensing operation of the dispensing mechanism 109 to carry in the reagent and then carrying it out, the reagent grasping mechanism 110 moves between the reagent tray 107 and the reagent disk 104 many times. It can be suppressed, and the time required for replacement of the reagent container 120 can be optimized to improve the operation efficiency of the operation of the set of carry-out and carry-in.
- control unit 114 When the control unit 114 is requested to carry out and carry in the reagent from the reagent disk 104 during the analysis, the control unit 114 stops the dispensing operation of the first reagent dispensing mechanism 108 and the second reagent dispensing mechanism 109. Have the reagents carried in and out later. On the other hand, when the carry-out and carry-in of the reagent are requested when the analysis is not performed, it is desirable to carry out the carry-out and carry-in of the reagent continuously.
- the time for interrupting the dispensing is performed if the loading and unloading are performed as a set as in this embodiment. There is a risk of doubling.
- loading and unloading are performed separately during analysis, and loading and unloading are performed as a set at other times, so that the time required for replacement of the reagent container 120 can be optimized.
- Example 6 The automatic analyzer of Example 6 of the present invention will be described with reference to FIG.
- FIG. 15 is a top view of the automatic analyzer of the sixth embodiment.
- a detergent container 121 containing a detergent for cleaning the sample dispensing mechanism 112 and a detergent for cleaning the reaction vessel 103 is installed on an apparatus outside the reagent disk 104. May have been.
- These detergent containers 121 are transported from the detergent tray 1305 to their respective installation positions by the consumables transport mechanism 1303 and the consumables gripping mechanism 1304.
- the second reagent dispensing mechanism 109 Since the second reagent dispensing mechanism 109 has an operation for R2 dispensing and an operation for R3 dispensing, if the sample dispensing is interrupted once, the timing for stopping the second reagent dispensing mechanism twice occurs. Therefore, if one detergent can be carried in by stopping the second reagent dispensing mechanism 109 for one cycle, it is possible to carry in two detergents by interrupting one sample dispensing.
- the automatic analyzer of Example 6 of the present invention also has almost the same effect as the automatic analyzer of Example 1 described above.
- the mechanism for carrying in the reagent container 120 and the mechanism for transporting the detergent container 121 are different in this embodiment, the mechanism for transporting the reagent container 120 and the detergent container 121 may be the same. In that case, the reagent tray 107 and the detergent tray 1305 can be combined into one without being separated.
- the detergent for the sample dispensing mechanism and the detergent for the reaction vessel can be installed one by one is mentioned. Since the two automatic analyzers have two sample dispensing mechanisms, it may be possible to install two detergents for the sample dispensing mechanism or two detergents for the reaction vessel as spares. .. Even in that case, the carry-in can be carried out in the same manner.
- the detergent is exemplified in this embodiment, but for example, the consumables are installed outside the reagent disk 104, and the consumables transport mechanism 1303 and the consumables gripping mechanism 1304 are the consumables during the transport of the consumables. 2 It is necessary to temporarily stop the mechanism other than the mechanism directly related to the transportation in order to carry in new consumables or to carry out the consumed consumables as in the case of interfering with the reagent dispensing mechanism 109.
- the present invention can be suitably applied when a certain mechanism exists.
- consumables examples include detergents for cleaning reagent dispensing mechanisms 108 and 109, sample dispensing mechanisms 112, reaction vessels 103, disposable reaction vessels, and dispensing chips for dispensing samples. Be done.
