The calculating unit 73c calculates another analysis that can consume the reagent of the analysis unit in which the remaining amount of the reagent expires based on the management information.

  “Before starting analysis” means that the automatic analyzer 1 is turned on and a series of analysis processes are stopped. For example, pre-processing associated with a series of analysis processes is performed. When you are. The reagent expiration date is set by adding a predetermined period to the date and time when the reagent was manufactured, or set by adding a predetermined period to the date and time when the reagent container containing the reagent was opened.

  In the automatic analyzer 1 configured as described above, in each of the analysis units 3 to 5, the sample dispensing mechanism 30 is connected to the transport unit 23 for the plurality of reaction containers 39 that are sequentially transferred on the reaction table 37. The sample is dispensed from the sample container 25 stopped at the upper sample aspirating position, and the reagent dispensing mechanism 33 dispenses the reagent from the reagent container 31a in the reagent container 31. Thereafter, the photometric unit 35 measures the reaction solution obtained by reacting the sample and the reagent, and based on the measurement result, the component analysis of the sample is automatically performed. Then, the cleaning unit 36 cleans the reaction container 39 that has been measured by the photometry unit 35 while transporting it, and the unit control unit 38 outputs the analysis result of the sample to the central control unit 7.

  Here, with reference to the flowchart shown in FIG. 2, the reagent transfer information display process performed by the control unit 71 before the analysis is started will be described. In the following, a series of processing when performing the reagent transfer display processing of the reagent set corresponding to one analysis item will be described.

  First, the control unit 71 causes the acquisition unit 73a to acquire the amount of the reagent stored in the reagent container 31a stored in the storage unit 74 (step S101). Thereafter, the control unit 71 causes the acquisition unit 73a to acquire the scheduled usage amount of the reagent stored in the storage unit 74 (step S102).

  Thereafter, the control unit 71 generates the remaining amount of the reagent in the reagent container 31a based on the amount of the reagent stored in the reagent container 31a acquired by the reagent management unit 73 in the determination unit 73b and the planned usage amount of the reagent. Or not (step S103). When the determination unit 73b determines that there is a remaining amount of reagent in the reagent container 31a (step S103: Yes), the control unit 71 causes the acquisition unit 73a to acquire the analysis date and time stored in the storage unit 74 (step S104). ). Thereafter, the control unit 71 causes the acquisition unit 73a to acquire the expiration date after manufacture of the reagent stored in the storage unit 74 (step 105). On the other hand, when the determination unit 73b determines that there is no reagent remaining in the reagent container 31a (step S103: No), the process proceeds to step S111.

  Thereafter, the control unit 71 determines that the reagent stored in the reagent container 31a has a remaining amount that expires after the manufacture based on the analysis date and time acquired by the acquisition unit 73a in the determination unit 73b. It is determined whether or not it occurs (step S106). When the determination unit 73b determines that the reagent stored in the reagent container 31a has a remaining amount that expires after manufacture (step S106: Yes), the control unit 71 is stored in the reagent container 31a in the output unit 75. The fact that the reagent has a remaining amount that will expire after manufacture, for example, a post-manufacturing expiration message M1 shown in FIG. 3 is output and this is notified (step S107). On the other hand, when the determination unit 73b determines that the reagent stored in the reagent container 31a does not have a remaining amount that expires after manufacture (step S106: No), the control unit 71 stores the reagent stored in the storage unit 74. The reagent management part 73 is made to acquire the expiration date after opening (step S108).

  Thereafter, the control unit 71 determines that the reagent stored in the reagent container 31a has a remaining amount that expires after opening based on the analysis date and time acquired by the acquiring unit 73a in the determination unit 73b and the expiration date after opening the reagent. It is determined whether or not it occurs (step S109). When the determination unit 73b determines that the reagent stored in the reagent container 31a has a remaining amount that expires after opening (step S109: Yes), the control unit 71 is stored in the reagent container 31a in the output unit 75. The fact that the remaining amount that will expire after opening is generated in the reagent, for example, the after-opening expiration message M2 shown in FIG. 4 is output and this is notified (step S110). On the other hand, when the determination unit 73b determines that the reagent stored in the reagent container 31a does not have a remaining amount that expires after opening (step S109: No), the process proceeds to step S111.

  Thereafter, the control unit 71 determines whether or not the determination process by the determination unit 73b has been completed for all the analysis units (step S111). When the determination process by the determination unit 73b is completed for all the analysis units (step S111: Yes), the process proceeds to step S112. On the other hand, when the determination process by the determination part 73b is not complete | finished by all the analysis units (step S111: No), it transfers to step S101 and repeats the process of step S101-step S110 mentioned above.

  Thereafter, the control unit 71 determines whether or not there is an instruction to display reagent transfer information from the storage unit 74 (step S112). Specifically, based on the reagent information menu M3 shown in FIG. 5, it is determined whether there is an instruction to display reagent transfer information. When there is an instruction to display reagent transfer information (step S112: Yes), the control unit 71 manages other analysis units that can consume the reagent of the analysis unit in which the remaining amount of the reagent expires in the calculation unit 73c. Calculation is performed based on the information (step S113). On the other hand, when there is no instruction to display reagent transfer information (step S112: No), this process ends.

  After that, the control unit 71 causes the output unit 75 to consume another reagent in the analysis unit in which the reagent calculated by the calculation unit 73c has a remaining expiration date, such as the reagent transfer message M4 illustrated in FIG. Is output (step S114), and the process is terminated.

  Here, an outline of the calculation performed by the calculation unit 73c will be described in detail. Based on the analysis information and management information of the reagent information menu M3 shown in FIG. 5, the calculation unit 73c calculates another analysis unit that can consume the reagent of the analysis unit in which the remaining amount of the reagent expires. Specifically, in the analysis item “CHOLESTEROL”, the reagent number stored in the reagent storage 31 is compared with the planned use amount of the reagent of the analysis unit 3 as of July 17, 2008 (Thursday). The reagent container 31a “0001” has a remaining amount of reagent of 30 ml. For this reason, the analysis unit 3 has a remaining amount of reagent of 20 ml after the end of the analysis. Since the expiration date of this remaining amount is August 30, 2008, the remaining amount of the reagent does not expire.

  In contrast, the analysis unit 4 has a reagent usage amount of 40 ml, whereas the reagent containers 31a with the reagent numbers “0002”, “0003”, and “0004” stored in the reagent storage 31 Are 25 ml, 5 ml, and 15 ml, respectively. At this time, the analysis unit 4 has 5 ml of reagent remaining after the end of the analysis, and the expiration date of this remaining amount is 17:00 on July 17, 2008. Therefore, if the analysis is executed as it is, the remaining amount of the reagent 5 ml in the analysis unit 4 expires. Therefore, when the reagent container 31a with the reagent number “0003” of the analysis unit 4 is moved to the analysis unit 3, the remaining amount of the reagent in the analysis unit 3 becomes 25 ml after the analysis is completed, but the expiration date is August 30, 2008 Therefore, there is no waste of reagents. Therefore, the calculation unit 73c calculates, as the analysis unit 3, an analysis unit that can consume the reagent container 31a having the reagent number “0003” that contains the reagent whose remaining amount of the analysis unit 4 expires. In this case, the analysis unit 3 uses the reagents in the order of the reagent container 31a having the reagent number “0003” and the reagent number “0001”.

  Here, an outline of the reagent transfer process executed by the automatic analyzer 1 before the start of analysis based on the reagent transfer message M4 shown in FIG. 6 will be described. The control unit 71 inputs a control signal to the transfer control unit 62 based on the above calculation result of the calculation unit 73c, and the transfer control unit 62 controls the operation of each unit based on this control signal. The reagent transfer unit 61 pulls out the reagent container 31a with the reagent number “0003” stored in the reagent storage 31 of the analysis unit 4 onto the reagent transport line unit 60b, and the transport unit 60 drives the reagent transport line unit 60b. The reagent container 31 a with the reagent number “0003” is transported to the analysis unit 3. Thereafter, the reagent transfer unit 61 pushes the reagent container 31a of the reagent number “0003” stopped at a predetermined position into the reagent storage 31 of the analysis unit 3. In this way, the automatic analyzer 1 executes the reagent transfer process before starting the analysis so that the reagent whose remaining amount expires is transferred to another consumable analysis unit and used up. When the reagent is moved, the automatic analyzer 1 calibrates the moved reagent in order to ensure analysis accuracy before starting the analysis.

  In the first embodiment, before the start of analysis, the determination unit 73b performs the analysis for each of the analysis units 3 to 5 based on management information including at least the reagent liquid amount, the expiration date, and the planned usage amount acquired by the acquisition unit 73a. It is determined whether or not the remaining amount of the reagent expires, and the output unit 75 manages other analysis units that can consume the reagent of the analysis unit in which the remaining amount of the reagent expires by the calculation unit 73c. Since the result calculated based on the information is output and the fact that the remaining amount of the reagent expires is notified, it is possible to reduce the waste of the remaining reagent due to the expiration.

  In the first embodiment, another analysis unit capable of consuming a reagent whose remaining amount expires is calculated based on the management information, and other analysis units containing a plurality of reagents whose remaining amount expires are stored. In order to prevent the remaining amount of the reagent from being expired, it is not necessary to concentrate the analysis process in one analysis unit. The analysis process can be performed efficiently without reducing the processing capacity of the analysis process.

(Embodiment 2)
Next, the second embodiment will be described. FIG. 7 is a schematic diagram showing an outline of an automatic analysis system 100 including an automatic analyzer according to the second embodiment.

  The storage unit 81d is realized using a hard disk that magnetically stores information, and a memory that loads various programs related to this process from the hard disk and electrically stores them when the automatic analyzer A1 executes the process. Various information including the analysis result of the specimen is stored. The storage unit 81d stores the liquid amount in each reagent container 31a calculated by the control unit 81a, the planned usage amount, and management information related to the expiration date.

  The output unit 81e is realized by a display, a printer, a speaker, and the like, and outputs various information including the analysis result of the sample. The transmission / reception unit 81 f has a mechanism as an interface that transmits and receives information according to a predetermined format via the communication network N. The transmission / reception unit 81f outputs, via the communication network N, management information related to the liquid amount, the expiration date, and the scheduled usage amount in each reagent container 31a accommodated in the reagent storage 31 to the management server H1.

  The management server H1 has the same configuration as the central control device 7 provided in the automatic analyzer 1 according to the first embodiment. Therefore, parts corresponding to the parts of the central control device 7 in the management server H1 are assigned the same reference numerals as those of the central control device 7. The reagent management unit 73 of the management server H1 acquires the management information and reagent information of the reagent in each reagent container 31a stored in the storage unit 81d of each of the automatic analyzers A1 to Am via the communication network N.

The processing is performed under the flowchart shown in FIG. That is, the automatic analysis system 100 determines whether or not the remaining amount of the reagent expires for each of the automatic analyzers A1 to Am. When the determination unit 73b determines that there is a remaining amount that expires, the output unit 75 of the management server H1 determines the amount of the reagent whose remaining amount expires by the calculation unit 73c and the automatic analyzers A1 to Am.
