The present invention relates to an automatic analysis system that performs a quantitative and qualitative analysis of a biological sample such as blood, plasma, serum, urine, and other body fluids (hereinafter, referred to as a sample or a specimen), and an information takeover method in such an automatic analysis system.
An example of a method for shortening time from a failure of a medium including a device database until a user can analyze again, by simplifying a recovery operation of the database before the failure without executing a registration operation or a calibration operation of a reagent residual amount, and checking integrity of the recovered database, PTL 1 describes arranging a backup of the database in an auxiliary operation unit and arranging a code for checking integrity of the database after recovery in an analysis measurement module.
An automatic analyzer that automatically performs a quantitative and qualitative analysis of a sample is used in many medical institutions or the like, particularly hospitals and clinical laboratory centers that need to process many patient samples in a short time.
As the automatic analyzer described above, various types of small, medium, and large automatic analyzers are developed in accordance with a sample processing capacity required by each medical institution.
As a software element that supports the automatic analyzer, there is software for operation unit and controller. An item requested by a user and a setting specified by the user with the operation unit are analyzed by the controller operating each mechanism in the automatic analyzer in accordance with the item and the setting.
In relation to a technique for acquiring cumulative information of such an automatic analyzer, PTL 1 describes constructing a backup of a database of device-specific information such as calibration curve information and reagent residual amount information using a storage medium external to a device, and restoring the database when the medium held by the device fails.
By acquiring cumulative information of an automatic analyzer, in particular, cumulative information such as a device adjustment value, device activation cumulative time, and lamp operation cumulative time, it is possible to determine the number of replaced components and necessity of repair and maintenance.
Further, as an automatic analyzer, there is an integrated device that improves a processing capability and the like by integrating a plurality of analyzers, with a group of equipment including one analysis instrument and equipment that executes a pre-analysis operation of the analysis instrument serving as a single device (hereinafter, referred to as an automatic analysis system).
In recent years, the analyzers connected to the automatic analysis system are not limited to the same type, but include various types. For example, there are a biochemical analyzer for measuring cholesterol and the like in blood, and an immunoassay analyzer for measuring infectious diseases and the like. There is also a device to which a plurality of different types or the same type of analyzers are connected. Accordingly, a trend is shifted from simply measuring large numbers of samples to measuring a wide variety of items.
Here, in recent years, the number of measurement items is increased due to combination of analyzers, and product life is longer due to improvement of durability of the analyzers. In such a situation, when a user replaces a device, there is a requirement of repairing and maintaining a recovered automatic analyzer again, renewing components, replacing consumable items, or the like.
However, the technique described in PTL 1 totally does not consider acquisition and takeover of cumulative information for maintenance when a device configuration in an automatic analysis system is changed, and is required to be improved.
For example, in a state in which in absence of cumulative information, operation time and the number of operations of the component are unknown in the repair and maintenance described above, and a visual check is performed for such a reason. However, in such a visual check, unnecessary components may be replaced, and a replacement component price is added to a product price. Similarly, there is a concern that a deteriorated component to be replaced may be left non-replaced, resulting in a case of an initial failure.
Further, a user who owns a plurality of automatic analysis systems in which a plurality of analyzers are integrated requires to rearrange layout of a device configuration in accordance with an environment due to a change of layout in an examination room or the like. In such a case as well, it is necessary to continue accumulate cumulative information of each device after changing the layout of the device configuration, as in a case of resale. However, no such mechanism exists in the related art, and a technique for performing appropriate management is needed.
The invention provides an automatic analysis system and an information takeover method in the automatic analysis system, in which repair and maintenance can be accurately executed at an appropriate timing even when a change occurs in a system configuration.
The invention includes a plurality of methods for solving the problems described above, one example of which is an automatic analysis system. The automatic analysis system includes: two or more analyzers having unique identification information and cumulative information associated with the unique identification information, and configured to analyze a sample; and a control device configured to control operations of the analyzers and manage the unique identification information and the cumulative information of each of the analyzers. When the analyzers in a system are rearranged, the control device takes over the cumulative information that a newly introduced analyzer has in a pre-rearrangement system based on the unique identification information, and manages cumulative information in a new system based on the taken-over cumulative information.
According to the invention, repair and maintenance can be accurately executed at an appropriate timing even when a change occurs in a system configuration. Problems, configurations, and effects other than those described above will be further clarified with the following description of embodiments.
Hereinafter, embodiments of an automatic analysis system and an information takeover method in the automatic analysis system according to the invention will be described with reference to the drawings. In the drawings used in the present specification, the same or corresponding components are denoted by the same or similar reference numerals, and repeated description of these components may be omitted.

The above is the configuration of the automatic analysis system 1.
A sample analysis processing of a sample performed by the automatic analysis system 1 as described above is generally executed in the following procedure.
A user gives an analysis instruction to the automatic analysis system 1 using the display unit 303 and the input unit 304. The analysis instruction is stored in the storage unit 302 and transmitted to a target analyzer among the sampler device 101, the biochemical analyzer 110, and the immunoassay analyzer 210 via the control device 300. The target device performs analysis operations as follows in accordance with the received analysis instruction.
The sampler device 101 sends out the sample racks 102 disposed on the sample rack supply unit 103 one rack at a time onto the transport line 105, and transports the sample rack 102 into the rack rotor 107.
The sample rack 102 transported to the rack rotor 107 is transported to the dispensing line 112 of the biochemical analyzer 110 or the dispensing line 212 of the immunoassay analyzer 210 in accordance with a measurement item requested by the control device 300.

Then, it is checked whether a writing target is checked in the respective cumulative information selection checkboxes 806 (step S1403). When none are checked, an error screen is displayed (step S1409), and the processing returns to step S1401. On the other hand, when the write target is checked, the processing proceeds to step S1404.
Next, when the cumulative information is written to the external medium 10, it is checked whether the path input in the information storage path input box 804 exists (step S1404). When the folder of the path does not exist, an error screen is displayed (step S1410), and the processing returns to step S1401. On the other hand, when the folder of the path exists, the processing proceeds to step S1405.
Next, it is checked whether a cumulative information file exists in the external medium 10 (step S1405). When no files exist, an error screen is displayed (step S1411), the processing returns to step S1401. On the other hand, when a file exists, the processing proceeds to step S1406.
Next, it is checked whether the serial number selected in the device serial number selection field 801 matches a serial number of the key information included in the cumulative information (step S1406). When the serial numbers do not match, an error screen is displayed (step S1412), and the processing returns to step S1401. On the other hand, when the serial numbers match, the processing proceeds to step S1407, and reading from the external medium 10 is started (step S1407).
Next, effects according to the present embodiment will be described.
The above described automatic analysis system 1 according to Embodiment 1 of the invention includes: two or more analyzers of a biochemical analyzer 110 and an immunoassay analyzer 210, which have unique identification information and cumulative information associated with the unique identification information, and analyze a sample; and a control device 300 that controls operations of the biochemical analyzers 110 and the immunoassay analyzer 210 and manages the unique identification information and the cumulative information of each of the biochemical analyzer 110 and the immunoassay analyzer 210. When the biochemical analyzer 110 and the immunoassay analyzer 210 in a system are rearranged, the control device 300 takes over the cumulative information that the newly introduced biochemical analyzer 110 and immunoassay analyzer 210 have in a pre-rearrangement system based on the unique identification information, and manages cumulative information in a new system based on the taken-over cumulative information.
Accordingly, it is possible to take over cumulative information even an analyzer is relocated to a different system, and to continuously manage operating time, maintenance, adjustment values, and the like of respective operation mechanisms from a pre-rearrangement analysis system even in a newly configured analysis system. Therefore, since a device status can be accurately and reliably understood, repair and maintenance can be accurately executed at an appropriate timing. Accordingly, it is possible to respond more appropriately to new demands such as reuse of a part of analyzers in a case of reselling an automatic analysis system when new demand arises, or in a case of changing a layout of a device configuration.
The automatic analysis system 1 and the information takeover method in the automatic analysis system according to the present embodiment are very suitable for dealing with systems currently in operation through software updates.
Further, since the automatic analysis system 1 further includes the display unit 303 that displays information of the automatic analysis system 1, and the control device 300 causes the display unit 303 to display the device configuration screens 600 and 650 for setting the unique identification information, the unique identification information can be easily set and checked.
Further, since the control device 300 causes the display unit 303 to display the cumulative information setting screen 800 on which cumulative information can be read and written, work of an operator when a takeover operation is performed can be facilitated, and takeover can be more accurately and reliably performed.
Further, since the control device 300 can write and read the unique identification information and the cumulative information to and from the external medium 10, unique identification information and cumulative information associated with the unique identification information can be easily backed up as appropriate, and work can be easily performed in a case of takeover.
Further, since the automatic analysis system 1 further includes the storage unit 302, and the control device 300 records a device serial number as unique identification information in the storage unit 302, serial numbers provided in a system can be basically reused, and can be easily applied to existing systems and devices.
Further, since the automatic analysis system 1 further includes the barcode reader 131 and 152, and the control device 300 can write out the unique identification information as a barcode, and manages the bar-coded unique identification information read by the barcode readers 131 and 152, a possibility of an input error can be eliminated and a possibility of an error occurring in a takeover operation can be reduced compared to a case of manual input by a service person or the like.
Further, since the external medium 10 is one or more of a USB medium, a CD medium, and a DVD medium, appropriate backup can be further performed, and a takeover operation can be facilitated.
An automatic analysis system and an information takeover method in the automatic analysis system according to Embodiment 2 of the invention will be described below.
Unlike Embodiment 1 in which the automatic analysis system and the information takeover method in the automatic analysis system are suitably applied to systems currently in operation by software updates, the automatic analysis system and the information takeover method in the automatic analysis system according to the present embodiment are suitable for devices to be manufactured and shipped in the future.
When an analyzer in a system is to be rearranged, in order to more accurately take over cumulative information in the pre-rearrangement system, it is desirable to use unique identification information that does not overlap with that of other automatic analysis systems and analyzers.
Therefore, the device configuration screen 650 shown in
Other configurations and operations are substantially the same as those of the automatic analysis system and the information takeover method in the automatic analysis system according to Embodiment 1 described above, and details thereof are omitted.
The automatic analysis system and the information takeover method in the automatic analysis system according to Embodiment 2 of the invention substantially have the same effects as in the automatic analysis system and the information takeover method in the automatic analysis system according to Embodiment 1 described above.
An automatic analysis system and an information takeover method in the automatic analysis system according to Embodiment 3 of the invention will be described below.
In Embodiment 1, a case in which the external medium 10 is illustrated as a location that can be selected in the information storage location selection field 803 on the cumulative information setting screen 800, but in the present embodiment, the control device 300 is configured to be able to transmit cumulative information to a record medium of a host computer connected to the automatic analysis system 1 via a network instead of the external medium 10, and manages the cumulative information in the record medium of the host computer.
More specifically, the host system can be selected in the information storage location selection field 803 on the cumulative information setting screen 800. When the execute button 807 is selected, unique identification information input on the cumulative information setting screen 800 and cumulative information are transmitted to the host computer and managed by the host system.
Then, when an operation for requesting reading is performed, the control device 300 requests a check from the record medium of the host computer, and when cumulative information associated with unique identification information exists in the host system, the control device 300 receives the corresponding cumulative information.
Other configurations and operations are substantially the same as those of the automatic analysis system and the information takeover method in the automatic analysis system according to Embodiment 1 described above, and details thereof are omitted.
The automatic analysis system and the information takeover method in the automatic analysis system according to Embodiment 3 of the invention substantially have the same effects as in the automatic analysis system and the information takeover method in the automatic analysis system according to Embodiment 1 described above.
Further, since the control device 300 is configured to be able to transmit the cumulative information to the record medium of the host computer connected to the automatic analysis system 1 via the network, and manages the cumulative information in the record medium of the host computer, there is no room for a risk of loss of cumulative information due to loss that may occur in the external medium 10 or the like, and takeover can be performed more reliably.
Further, the control device 300 transmits the unique identification information input on the cumulative information setting screen 800 to the host computer. When the cumulative information associated with the unique identification information exists in the record medium of the host computer, the control device 300 receives the corresponding cumulative information, and the takeover can be reliably achieved.
