  In addition, the inventory management unit 104 according to the present embodiment uses the association table T1 stored in the storage unit 109 to perform biochemical examinations a predetermined number of times or more among a plurality of examination contents that can be selected by the examination content selection unit 101. Is provided with a determination unit 105 that determines the inspection contents for which no inspection supplies that can be executed are held.

  In the present embodiment, a reference inspection number table (not shown) in which an average inspection number (predetermined number) of each inspection content performed for a predetermined period for each inspection content ID is associated with the inventory management DB. . The predetermined period is an arbitrarily set approximate period from ordering to delivery. Based on the association table T1 and the reference inspection number table, the determination unit 105 sums the quantity of inspection items necessary for executing the average number of inspections for all types of inspection content IDs registered in the determination table. Is calculated, and a reference stock table T4 (not shown) in which the total amount of inspection products required for each inspection product is associated is created and registered in the inventory management DB. Then, the determination unit 105 compares the reference stock table T4 and the stock table T3, and for the inspection product ID common to both the tables T3 and T4, the inspection product whose inventory is less than the quantity registered in the reference stock table T4. The inspection content using the specified inspection product is specified as the inventory low inspection set as the inventory low inspection product.

  Note that the present invention is not limited to this embodiment, and the predetermined number of times can be arbitrarily set according to usage conditions such as the frequency of various examinations and user requests. The predetermined number of times may be set to a different value for each inspection content, or a single value may be set for all the inspection details. In addition, the above inventory management unit 104 subtracts the number of inventories of the inspection product from the inventory table T3 based on the inspection product table T2, the process of creating the reference inventory table T4, and the inventory unit with the inventory inventory scarce inspection product and inventory by the determination unit 105. The processing for specifying the minor inspection contents may be executed at an arbitrary timing according to the user's request and use conditions. Further, the creation of the reference inventory table T4 is not necessarily performed every time the processing for specifying the inventory inventory inspection item and the inventory inventory inspection content by the determination unit 105 is performed, but only at a predetermined opportunity such as when the reference inspection frequency table is updated. You may go to

  In addition, the determination unit 105 may specify the content of the test by any method that can specify the content of the test that does not have a test article that can be executed a predetermined number of times or more.

  In addition, the inventory management unit 104 periodically removes inspection products whose expiration date has passed from the inventory table T4. In addition, the determination unit 105 can use the inspection supplies whose expiry date expires during the above approximate period in order to prevent the shortage of the inventory of the inspection supplies due to the inability to use the inspection supplies whose expiry date has passed. May be removed from any inspection product. In such a case, it is possible to prevent a shortage of inventory due to the inspection product becoming unusable after the expiration date at the time of inspection. Further, the inventory table T3 may have an arbitrary configuration regardless of FIG. For example, fields such as purchase unit and expiration date may be omitted, and further fields may be provided.

  The inspection product ordering unit 107 acquires the inspection product ID of the inventory low inspection product from the determination unit 105 when the determination unit 105 determines that the inventory low inspection set exists. Then, based on the acquired inspection product ID, the inspection product ordering unit 107 is pre-registered in the inventory management DB in the inventory management unit 104, and for each inspection product ID, order information necessary for ordering such as an ordering party and a purchase unit is provided. Order information necessary for ordering is extracted from an associated supplier table T5 (not shown). Based on the extracted ordering information, the inspection product ordering unit 107 places an order for a low inventory inspection product using a known ordering system connected to the biochemical inspection apparatus 1 via the network.

  The inspection product ordering unit 107 can apply any known ordering method as long as it can order an inspection product based on information for specifying the inspection product. For example, based on the ordering information extracted by the inspection product ordering unit 107, the inspection product may be directly ordered to the ordering party by e-mail or FAX. The inspection product ID acquired by the inspection product ordering unit 107 and this inspection product The ID ordering request is transmitted to an external ordering system connected to the chemical inspection apparatus 1, and the external ordering system extracts ordering information required for ordering such as the ordering party and the number of orders, and sends the inspection item to the ordering party. You may place an order.

  When the determination unit 105 determines that there is an inventory-poor inspection set, the notification unit 108 acquires the inspection item ID of the inventory-poor inspection product from the determination unit 105. Then, the notification unit 108 specifies the inspection product name corresponding to the inspection product ID acquired by the inventory management unit 104. The specified inspection product name and inspection product ID are displayed in a warning on the display window 18a, and transmitted to the computer terminal connected to the biochemical testing apparatus 1 via the network. Notice.

  Further, the error determination unit 106 acquires information on the execution result of the inspection from the inspection execution control unit 103, and determines whether or not the result of each executed inspection item is an error that needs to be re-inspected. The inspection execution control unit 103 performs re-inspection when the error determination unit 106 determines an error that requires re-inspection of the inspection item, and includes information related to the inspection product used for the re-inspection. Update. Here, the inspection execution control unit 103 updates the inspection product table T2 by adding the type and usage amount of the inspection product used for re-inspection to the inspection product table T2.

  In general, in a biochemical test apparatus, it is often the case that the test value is overranged and the effective test cannot be performed because the viscosity of the specimen is too high. In the present embodiment, the error determination unit 106 determines that an overrange error in which an inspection value exceeding the detection range is detected is an error that requires reinspection, and determines other errors as errors that do not require reinspection. Then, in the case of an overrange error, the test execution control unit 103 increases the sample dilution rate in order to keep the test value within the detection range. That is, after the concentration at which the specimen is diluted with the diluent is reduced, the test execution unit 120 performs retesting. The inspection execution control unit 103 is used for reinspection based on the dilution rate set by the user from the operation panel 18 for reinspection or a predetermined reinspection dilution rate registered in the association table T1. The amount of diluent is calculated, and the amount of diluent used for re-inspection is added to the inspection article table T2 and updated. Similarly, for other inspection products such as the nozzle tip 12 used for the re-inspection, the quantity used in the re-inspection is added to the inspection product table T2 and updated. Such update processing and re-inspection of the inspection product table T2 may be executed in an arbitrary order, or may be executed simultaneously.

  FIG. 7 is a flowchart for explaining the processing flow of the biochemical test apparatus 1. Next, the operation of the biochemical test apparatus 1 will be described with reference to FIG.

  First, before performing analysis, a biochemical analysis cartridge 7 loaded with a sample container 10 containing a sample outside the apparatus and a plurality of types of dry analysis elements 11 corresponding to the measurement items is prepared. Here, the dry analytical elements 11 corresponding to a plurality of measurement items constituting the health examination set are loaded in the biochemical analysis cartridge 7.

  The user removes the protective cover 19 and loads the biochemical analysis cartridge 7 holding the sample container 10 and the dry analytical element 11 in the sampler tray 2. In addition, the nozzle tip 12, the mixing cup 13, the diluent container 14, and the reference liquid container 15 that are consumables are loaded into the sampler tray 2. In the form of FIG. 2, a consumable cartridge 8 is loaded. Then, the examination content ID of the health examination set is input from the operation panel 18. Then, the examination content selection unit 101 acquires the inputted examination content ID and selects the examination content specified by the obtained examination content ID (S01).

  Next, the conversion unit 102 acquires second information corresponding to the acquired inspection content ID as the inspection product table T2 based on the association table T1 (S02).

  Next, the test execution control unit 103 controls the test execution unit 120 to execute the following test item execution process in the order in which the dry analytical element 11 corresponding to each test item is loaded in the biochemical analysis cartridge 7. (S03).

  First, the whole blood in the sample container 10 is filtered by the blood filtration unit 6 to obtain a plasma component. Next, the biochemical analysis cartridge 7 of the sample to be measured by rotating the sampler tray 2 is stopped at a position corresponding to the spotting portion 4. The dry analytical element 11 is conveyed from the biochemical analysis cartridge 7 to the spotting part 4 by the element conveying member 91 of the conveying part 9.

  When the read inspection item is ion activity measurement, different processing is performed depending on the dilution request item. When the read inspection item is colorimetric measurement, the sampler tray 2 is rotated to move the nozzle tip 12 below the spotting nozzle 53 and is attached to the spotting nozzle 53. Subsequently, the specimen container 10 is moved, the spotting nozzle 53 is lowered, the specimen is sucked into the nozzle tip 12, the spotting nozzle 53 is moved to the spotting part 4, and the specimen is spotted on the dry analysis element 11. .

  Then, the dry analysis element 11 on which the specimen is spotted is inserted into the incubator 3. When the dry analytical element 11 is inserted, the element chamber 32 of the incubator 3 is rotated, and the inserted dry analytical element 11 is sequentially moved to a position facing the photometric head. Then, after a predetermined time, the reflection optical density of the dry analysis element 11 is measured by the photometric head. After completion of the measurement, the element chamber 32 is returned to the position at the time of insertion, and the dry analytical element 11 after the measurement is pushed out to the center side by the element conveying member 91 and discarded. Then, the measurement result is output, and the used nozzle tip 12 is removed from the spotting nozzle 53 and discarded.

  When the read inspection item is measurement of ion activity, the biochemical analysis cartridge 7 loaded with the electrolyte type dry analytical element 11 is loaded into the biochemical inspection apparatus 1 and the electrolyte type dry analytical element is loaded. 11 is used for inspection. First, the nozzle tip 12 is attached to one spotting nozzle 53, and the specimen is aspirated. Next, another nozzle tip 12 is attached to the other spotting nozzle 53 and the reference liquid is sucked from the reference liquid container 15. Next, the sample is spotted on one liquid supply hole of the dry analytical element 11 by one spotting nozzle 53, and the reference liquid is spotted on the other liquid supply hole of the dry analytical element 11 by the other spotting nozzle 53. To wear.

  Then, the dry analytical element 11 on which the specimen and the reference liquid are spotted is inserted from the spotting portion 4 into the element chamber 32 of the incubator 3. When this dry analytical element 11 is inserted into the incubator 3, the ion activity is measured by the potential difference measuring means. After the measurement is completed, the measured dry analytical element 11 is discarded by the element conveying member 91 to the discard port 33 at the center of the incubator 3. Then, the measurement result is output, and both used nozzle tips 12, 12 are removed from both spotting nozzles 53, 53 and discarded.

  Further, when the read inspection item is a dilution request item, the processing is the same as the re-inspection processing (S05) described later, and is omitted here.

  Then, the error determination unit 106 determines whether or not the measurement result is an error that requires re-inspection. If the error is not an error that requires re-inspection (N in S04), the inspection item execution process ends. Then, the inspection execution control unit 103 performs the above-described inspection item execution processing until the dry analytical element 11 loaded in the biochemical analysis cartridge 7 is exhausted, that is, until all the inspection items of the inspection set are completed (Y in S07). Repeat (S03 to S06).

  On the other hand, the error determination unit 106 determines whether or not the measurement result is an error that requires re-examination. If the measurement result is an error that requires re-inspection (Y in S04), the error determination unit 106 performs re-inspection (S05). Specifically, when the blood concentration is too high to perform an accurate test, the sampler tray 2 is moved and the nozzle tip 12 is attached to the spotting nozzle 53. Next, the sampler tray 2 is moved, the spotting nozzle 53 is lowered on the sample, and the sample is sucked into the nozzle chip 12. After moving the sampler tray 2 and dispensing the sucked sample from the nozzle tip 12 to the mixing cup 13, the used nozzle tip 12 is removed. Next, a new nozzle tip 12 is attached to the spotting nozzle 53, and the diluent is sucked into the nozzle tip 12 from the diluent container 14. The sucked diluted liquid is discharged from the nozzle tip 12 to the mixing cup 13. Then, the nozzle tip 12 is inserted into the mixing cup 13 and agitation is performed by repeating suction and discharge. After stirring, the diluted specimen is sucked into the nozzle chip 12, the spotting nozzle 53 that sucked the diluted specimen is moved to the spotting section 4, and the specimen is spotted on the dry analytical element 11. Similarly, photometry, element discard, result output, and chip discard are performed, and the reinspection process is terminated.

  In addition, the inspection execution control unit 103 executes the reinspection process and at the same time updates the inspection article table T2 by adding the amount using the nozzle tip 12, the dry analysis element 11, and the diluent used in the reinspection (S06). .

  After the inspection article table T2 is updated, the inspection execution control unit 103 until the dry analytical element 11 loaded in the biochemical analysis cartridge 7 is eliminated, that is, until all the inspection items of the inspection set are completed (S07). Y), the inspection item execution process (S03 to S06) is repeated one after another.

  When the inspection execution process by the inspection execution control unit 103 ends (N in S07), the inventory management unit 104 acquires the inspection product table T2 from the storage unit 109, and is registered in the inspection product table T2 from the inventory table T3. The inventory table T3 is updated by subtracting the inspection article by the registered quantity (S08).

  Then, the determination unit 105 creates a reference stock table T4 (not shown) in which the inspection supplies necessary for executing each inspection content a predetermined number of times and the quantities thereof are registered, and compares the reference stock table T4 with the stock table T3. Then, an inspection product with a smaller inventory than the quantity registered in the reference inventory table T4 is determined (S09). Then, the determined inspection product is specified as an inventory low inspection product, and the inspection content using the inventory low inspection product is specified as an inventory low inspection set.

  Next, the notification unit 108 notifies the computer terminal externally connected to the biochemical inspection apparatus 1 of the inventory shortage inspection item and the inventory low inspection content and displays a warning on the display window 18a (S10).

  Then, the inspection product ordering unit 107 places an inventory scarce inspection product on the basis of the inspection product ID, and ends the processing of the biochemical inspection apparatus 1 of the present embodiment (S11).

  In the embodiment as described above, by performing inventory management based on the inspection product table T2 (second information) converted based on the inspection contents (first information), the user individually supplies the inspection products. Even if it does not specify, since each inspection article used for inspection contents can be specified only by selecting information specifying inspection contents, inventory management can be performed easily and accurately.

  In addition, in the methods described in Patent Documents 1 to 3, they are registered in consumables such as diluents and inspection schedules that cannot be assigned with an identification code for each test unit because the amount used varies depending on individual instructions, for example, reagents. For consumables that are not used for inspection, it is necessary to manually input an identification code, and errors such as omissions cannot be sufficiently reduced. However, in the above-described embodiment, even when a consumable that does not have an identification code is included, each inspection article used for the inspection content can be automatically managed according to the inspection content. It is highly versatile for goods and can easily and accurately manage inventory.

  In the above embodiment, the examination content is selected by the operation panel. Instead, a doctor or the like instructs the examination content from a network-connected computer terminal, and selects the examination content as an input. Also good. In this case, even if there is a possibility that a user who is not familiar with the individual inspection items and consumables included in the inspection contents from the computer terminal connected to the network may select the inspection contents, the user can check the inspection contents or be in charge of the inspection. The inventory can be managed easily and accurately by selecting the inspection contents without confirming with the person in charge.

  In addition, the inventory management unit 104 in the biochemical inspection apparatus of the above embodiment uses the correspondence stored in the storage unit 109 to select a predetermined number of times or more from among a plurality of test contents that can be selected by the test content selection unit 101. A determination unit 105 is provided for determining the content of an inspection for which a test article capable of performing a biochemical inspection is not held. Such a determination unit 105 is not an essential component of the present invention, but by including the determination unit 105, it is possible to determine the content of the inspection that does not have the inspection article as necessary, and to determine whether or not the inspection is possible and to wear it out. Goods inventory can be properly managed.

  Moreover, in the said embodiment, the biochemical test | inspection apparatus 1 comprises the error judgment part 106 which judges whether a biochemical test | inspection is an error. The error determination unit 106 is not an essential component of the present invention, but includes the error determination unit 106 as in the above embodiment, and the test execution unit 120 determines that the error determination unit 106 has determined a biochemical test error. When the inventory management unit 104 updates the second information in accordance with the re-inspection performed, the user individually determines the consumption of consumables generated in response to the re-inspection. In addition, it is possible to save time and effort to input to the management ledger, prevent human error such as forgetting to input, and perform inventory management by appropriately reflecting the consumption of consumables caused by re-inspection. For this reason, inventory management can be performed more easily and accurately.

  Moreover, in the said embodiment, the test | inspection execution part 120 in the biochemical test | inspection apparatus 1 uses the dilution liquid contained in 2nd information according to the increased dilution rate while increasing the dilution rate of a test substance in a retest. Since the quantity is updated, the inventory management unit 104 can perform inventory management by appropriately reflecting the consumption of the consumables generated in response to the re-inspection. For this reason, inventory management can be performed more easily and accurately.

  In the above-described embodiment, the biochemical test apparatus 1 includes the notification unit 108 that notifies information related to the test content determined by the determination unit 105. Although the notification unit 108 is not an essential component of the present invention, since the notification unit 108 is provided in the present embodiment, the inspection contents in which the inspection supplies are not held in the inventory are transferred to the user in charge of inspection or ordering, the ordering system, or the like. By notifying, it is possible to call attention so as not to cause a shortage of inspection supplies, and it is possible to appropriately determine whether inspection is possible and manage inventory of consumables.

  Further, in the above-described embodiment, the biochemical test apparatus 1 includes the test product ordering unit 108 that orders test products that are insufficient for the test content determined by the determination unit 105. The inspection product ordering unit 108 is not an essential component of the present invention, but in the present embodiment, the inspection product ordering unit 108 includes the inspection product ordering unit 108. Management can be performed reliably. As a result, the burden on the user is reduced and the efficiency of measurement work can be improved.

  Further, the inspection product ordering unit 108 may treat all inspection products necessary for one inspection content as one set and place an order for the inspection product for each inspection content. For example, when all the inspection products registered in the inspection product table 2 in the above embodiment are sold as “health diagnosis set inspection products”, they may be ordered in units of “health diagnosis set inspection products”. In this case, since there is no need to order individual consumables, there is no omission of orders, and inspection items can be ordered accurately and easily.

  In each of the above-described embodiments, the biochemical inspection apparatus 1 causes the control unit 100 of the biochemical inspection apparatus 1 to perform inspection content selection processing, conversion processing, inventory management processing, discrimination processing, inspection product order processing, notification processing, and error determination. By incorporating each program that performs processing, the control unit of the biochemical test was made to function as a test content selection unit, a conversion unit, an inventory management unit, a discrimination unit, a test article ordering unit, a notification unit, and an error judgment unit However, instead of this, one of the inspection content selection unit, conversion unit, inventory management unit, determination unit, inspection product ordering unit, notification unit, error determination unit, or any combination thereof is connected to the biochemical inspection device.
