Description

  The present invention relates to an automatic analyzer for qualitative and quantitative determination of samples such as blood and urine, and more particularly to an automatic analyzer having a disk-shaped sample setting disk for setting a plurality of samples on a circumference or concentric circles. is there.

  In the field of automated analyzers that measure biological samples such as blood (serum, plasma, etc.) and urine, a barcode is affixed to the sample container in order to prevent sample mistakes due to human error such as incorrect sample installation. In many cases, it operates. In such an automatic analyzer, a bar code reader for reading the affixed bar code is held in the apparatus, and the sample information is optically recognized. Since many barcode readers are fixedly installed outside or inside the circumference of the disk on which the sample is mounted in current automatic analyzers, the disk reader is moved to the barcode reader reading position during sample sampling. The sample to be read cannot be moved by rotating the disk, and it is necessary to read the barcode by rotating the disk in the idle time until the next sample is sampled. It takes time to complete the reading of the barcode of the sample after the installation.

  Furthermore, if a barcode reading error is detected after the time has elapsed since the sample was installed, the user must return to the apparatus again, take out the sample, check the barcode, install it again, and start. For this reason, there arises a problem that the load on the user increases and the report of the measurement result of the sample is delayed. There are automatic analyzers that start dispensing after reading the barcodes of all samples. In this case, however, the sampling of the sample must be stopped until all the barcodes are read, which reduces analysis throughput. End up.

  As a technique for solving the above-mentioned problem, for example, in Patent Document 1, in order to speed up measurement of an emergency patient sample, a barcode reader on the inner circumference side is arranged at the center of the disk, and the barcode reader itself is rotated to rotate the sample. A method for quickly reading a barcode is disclosed. Patent Document 2 discloses a method of quickly reading a barcode of a sample, which includes a barcode reader that rotates along the circumference of a disk on which the sample is mounted.

  In the automatic analyzer described in Patent Document 1 or 2, it is necessary to perform irregular and irregular rotation in order to sample a sample, and accordingly, the barcode reader similarly performs irregular and irregular rotation. Do. Since both the sample disk and the barcode reader rotate with complex control, by any chance, such as software defects and hardware malfunctions, the position recognized by the barcode reader If the position at the reading position of the barcode reader is misaligned, the barcode of the wrong sample will be read, and barcode reading will continue without detection. There is a risk of making a difference.

  The present invention has been made in view of the above. In addition to being able to read the barcode of the sample regardless of the sampling of the sample, there is a risk of continuing the measurement while reading the barcode of the wrong sample. An object of the present invention is to provide an automatic analyzer that can be eliminated.

  The configuration of the present invention for achieving the above object is as follows.

  That is, a disk that holds a plurality of liquid containers in an annular shape, and includes a first holding part and a second holding part adjacent to each other, and a plurality of holding parts arranged in a concentric manner, and the holding part A driving device that rotates the container, a processing device that performs processing on the container held on the holding unit, and a container that is installed on the first holding unit and held on the second holding unit A first reading device that reads the identifier attached to the second holding device, and a second reading device that is installed on the second holding unit and reads the identifier attached to the container held on the first holding unit; And a storage device for storing information read by the reading device.

  According to the present invention, it is possible to read the barcode of the sample between adjacent disks, and it can be ensured that there is no deviation of the reading position from the read barcode information. The risk of differences can be eliminated and the reliability of the device can be improved.

  Embodiments of the present invention will be described below with reference to the drawings. In addition, a present Example is one of the forms of this invention, and is not limited to this form.

  FIG. 1 is a diagram schematically showing an overall configuration of an automatic analyzer according to an embodiment of the present invention.

  In FIG. 1, reference numeral 1-1 denotes a reaction disk, and a reaction vessel 1-2 is provided on the outer periphery of the reaction disk 1-1. The entire reaction disk 1-1 is maintained at a predetermined temperature by a heat insulating tank 1-3. Reference numeral 1-5 denotes a sample disk on which a sample is placed, and in this mechanism, a number of test tubes with barcodes 1-6 attached are installed. The sample in the test tube with the barcode attached is appropriately extracted by the nozzle 1-8 of the pipetting mechanism 1-7 and injected into the reaction container 1-2 at the sample dispensing position. A barcode reader 1-26 is attached to the sample disk. 1-9A and 1-9B are reagent disk mechanisms in which reagent bottles with barcode labels are installed. Each reagent disk mechanism 1-9A and 1-9B has a barcode reader 1-27 attached. At the time of reagent registration, a barcode is read and reagent bottle information corresponding to the position is registered, and a reagent pipetting mechanism 1-10 is installed in each reagent disk. Reference numeral 1-11 arranged close to the reagent disk mechanisms 1-9A, 1-9B is a stirring mechanism. 1-12 is a multi-wavelength photometer, 1-13 is a light source, and a reaction vessel 1-2 for accommodating a photometric object is disposed between the multi-wavelength photometer 1-12 and the light source 1-13. Reference numeral 1-14 denotes a cleaning mechanism. Regarding the controller and signal processing system, 1-15 is a microcomputer (control unit), 2-16 is an interface, 1-17 is a log (logarithmic) converter, 1-18 is an A / D converter, 1-19 is A reagent dispensing mechanism, 1-20 is a washing water pump, and 1-21 is a sample dispensing mechanism. 1-22 is a printer for printing, 1-23 is a CRT as an operation screen, 1-24 is a hard disk as a storage device, 1-25 is an operation panel for inputting (keyboard, touch screen, mouse, etc.) Pointing device).

  The sample placed in the test tube with the barcode attached in FIG. 1 is copied according to the analysis parameters stored in the memory in the microcomputer (control unit) 1-15 input from the operation screen 1-23. A predetermined amount is dispensed into the reaction vessel 1-2 using the nozzle 1-8 of the petting mechanism 1-7. This bar code stores the measurement category associated with the sample. For example, the measurement category is information representing the degree of urgency such as urgent, urgent, or general. Note that information storage means such as RFID may be used instead of the barcode.

  Next, the reaction container 1-2 into which the sample is dispensed is transferred to the reagent dispensing position by rotating the reaction disk 1-1. Then, according to the analysis parameters stored in the microcomputer (control unit) 1-15, a predetermined amount of the reagent is dispensed into the reaction container 1-2 into which the sample has been dispensed using the nozzle of the reagent pipetting mechanism 1-10. Dispense.

  Thereafter, the sample and the reagent are stirred by the stirring mechanism 1-11 and mixed.

  When the reaction container 1-2 crosses the photometric position, the absorbance is measured by the multiwavelength photometer 1-12. The photometric absorbance is taken into the microcomputer (control unit) 1-15 via the Log (logarithmic) converter 1-17, the A / D converter 1-18, and the interface 1-16. This absorbance is converted into concentration data based on a calibration curve created from the absorbance of a standard sample solution measured in advance by an analysis method designated for each item. The measured component concentration data is output to a printer or a screen. Note that the PC 1-30 may be connected to the interface 1-16 via the network 1-19 to share information with a remote control or other automatic analyzer.

  In the above measurement principle, the operator performs various parameter settings necessary for measurement, specimen registration, reagent registration, analysis result confirmation, automatic analyzer maintenance, and the like on the operation screen 1-23.

  Next, an example of realization of the present invention will be shown.

  FIG. 2 is an example of a configuration diagram of a sample disk in the case of a dual disk using the present invention.

In FIG. 2, a sample disk A201 on the outer peripheral side and a sample disk B202 on the inner peripheral side are provided as holding parts for holding the sample container in an annular shape. These disks constitute a double disk, the sample disk A201 on the outer peripheral side is provided with sample setting positions 1 to 31, and the sample disk B202 on the inner peripheral side is provided with sample setting positions 32 to 62.
These outer peripheral side sample disk A 201 and inner peripheral side sample disk B 202 are configured as independently rotatable disks. The means for configuring the disk that can be rotated independently may be realized by two stepping motors or may be realized by switching with one stepping motor.

  Further, a barcode reader 203 for reading the barcodes of the samples 32 to 62 of the sample disk B202 is arranged on the outer sample disk A201. Similarly, the sample disk A201 is arranged on the inner sample disk B202. A barcode reader 204 for reading the barcodes of the sample positions 1 to 31 is arranged.

  In the present embodiment, the barcode reader is described as an example. However, the present invention is not limited to the barcode reader, and a QR code reader, an RFID reader, an IC tag reader, a sample container detector, and the like may be mounted. . A plurality of these may be mounted.

  In this embodiment, a sample disk on which a sample is mounted is described as an example. However, the present configuration may be applied to a disk on which a reagent is mounted, and is not particularly limited. When the present embodiment is applied to the reagent disk, the identifier attached to the reagent container can be read not only during the sampling of the reagent but also during the stirring of the reagent.

  Next, the barcode reading control of the sample in the configuration of FIG. 2 will be described with reference to FIGS.

  FIG. 3 shows a flow of operations when a barcode is read for a sample on the same sample disk as the sample disk on which the sample to be sampled is placed during sampling of the sample. In FIG. 3, sampling is performed from the sample setting position 1 on the sample disk A 201 as an example, and the position of the barcode reading target is the sample at the position 9 on the sample disk A 201 same as the sampling.

  In this case, it is necessary to read the barcode of the sample at position 9 with the barcode reader 204 installed on the sample disk B, but the sample disk A201 moves to the position of the barcode reader 204 by sampling the sample. I can't. Therefore, in this case, the sample disk B202 is moved, and the barcode reader 204 is moved clockwise by 8 positions so as to come onto the sample at position 9. By doing so, the barcode reader 204 for reading the position 9 of the sample disk A 201 can move onto the position 9 and can read the barcode.

  FIG. 4 shows an operation flow when a barcode is read for a sample on another sample disk on which a sample to be sampled is not placed during sampling of the sample. In FIG. 4, sampling is performed from the sample setting position 1 on the sample disk A 201 as an example, and the barcode reading target position is a sample at the position 55 on the sample disk B 202 different from the sampling.

  In this case, it is necessary to read the barcode of the sample at position 55 with the barcode reader 203 installed on the sample disk A, the sample disk B202 is moved, and the sample at position 55 is moved to the bar of the sample disk A201. Moves 7 positions clockwise so as to come onto the code reader 203. By doing so, the barcode can be read.

  As shown above, it is possible to select whether to move the barcode reader or the sample based on the relationship between the sample reading the barcode and the disk being sampled. The barcode can be read freely.

  Next, based on the example of the operation flow described with reference to FIG. 4, a check function for guaranteeing that no position shift has occurred will be described with reference to FIG.

  For example, in FIG. 4, it is assumed that an emergency additional sample is generated and placed at position 55 of the sample disk B 202 in a state where barcode reading of the positions 1 to 31 on the sample disk A 201 is completed. When the barcode reading is started in this state, as described above, the sample disk B202 is moved, and the position 55 is placed on the barcode reader 203 of the sample disk A201 in the clockwise direction for 7 positions. Move minutes. After this movement, the position 55 should be on the barcode reader 203 of the sample disk A201, and the barcode reader 204 of the sample disk B202 should have the position 8 from the relationship between the amount of movement and the disk. . Therefore, the barcode of the emergency additional sample at position 55 is read using the barcode reader 203 of the sample disc A201, and at the same time, the barcode of the sample on the barcode reader is read using the barcode reader 204 of the sample disc B202. Read the code and recognize the barcode.

  First, an example (case 1) in which no position deviation has occurred will be described. The barcode information 505 read by the barcode reader 204 of the sample disk B 202 is “H12345”, and the barcode reader 204 recognizes that the position 8 of the sample disk A has been read from the driving amounts of the sample disk A and the sample disk B. ing.

  When the check process is started in this state, first, a determination 501 of “Is the sample that should be on the barcode reader of the partner disk already barcode read?” Is executed. Accordingly, the barcode reading table 506 is searched, and the position 8 has already been read, and moves to the next determination 502. The barcode reading table 506 is stored in a storage device in the operation unit, and the position information read by each barcode reader and the read barcode information are stored in association with each other.

  Next, a determination 502 of “Is the information of the barcode read this time and the information of the barcode already read?” Is performed. Here, since the barcode information: “H12345” read this time and the barcode information: “H12345” stored with respect to position 8 of the barcode reading table 506 coincide with each other, the sample 55 read this time is physical. Therefore, it can be ensured that the position is correct, and the process proceeds to the check result OK determination 503 and the check process is terminated.

  Next, an example (case 2) in which a position shift has occurred will be described. The barcode 507 read by the barcode reader 204 of the sample disk B 202 is “G12345”, and the barcode reader 204 recognizes that the position 8 has been read.

  When the check process is started in this state, a determination 501 is first executed as in the case 1. The bar code reading table 508 is searched. Since the bar code has already been read, the position 8 moves to the next determination 502.

  Next, a determination 502 of “Is the information of the barcode read this time and the information of the barcode already read?” Is performed. Here, when the barcode information “G12345” read this time is compared with the barcode information “H12345” stored for the position 8 in the barcode reading table 508, it is found that there is a mismatch. As a result, there is a possibility that the sample 55 read this time is a physically different sample, and the process proceeds to the check result NG determination 504 to end the check process. As a result, it is possible to prevent erroneous measurement due to sample misplacement.

  As the subsequent behavior, the analyzer may be suspended by notifying the user of an alarm, or the reset operation for determining the position to be performed at the start of analysis is performed again, and the device automatically recovers and rereads the barcode. You may start.

  As described above, by inserting the check processing described above into this configuration, it is possible to guarantee the consistency of the position between adjacent disks, and to prevent the sample from being mixed due to a bar code reading error. A highly functional device can be provided.

  In this example, the barcode of the installed sample was read and it was checked that there was no position shift using this. However, the present invention is not particularly limited to this. In a disc configuration in which a fixed bar code indicating position information is attached between positions, this information may be read to check consistency. In addition, a fixed barcode indicating the position information is affixed to the surface of each position that is not in contact with the barcode reader so that the barcode information can be read when no sample is installed. It is also possible to use a method in which consistency can be checked even in a position where no sample is installed. By using a disk with the above configuration, in addition to batch-type operation in which patient samples are installed together and started analysis as in the conventional operation, each time a patient sample arrives, it is inserted into the sample disk as needed for analysis. It can also be used as a flexible operation to improve user convenience.

  In addition, since the barcode of the emergency additional sample can be read immediately, the emergency additional sample can be quickly measured, and the time required to report the measurement result of the emergency additional sample can be shortened.

  In addition, since it can shorten the time it takes for the barcode of all samples to be read after the user installs it, it is possible to detect samples with barcode reading errors early and prevent delays in reporting the measurement results of the samples. Can do.

  In addition, since a barcode reader that reads the barcode of the sample container on another adjacent sample disk is arranged, it is possible to read the barcode between the sample disks and read from the information of the read barcode. It can be guaranteed that there is no position shift. This eliminates the risk of sample misplacement and improves the reliability of the apparatus.

  Next, FIG. 6 shows the configuration of a sample disk when the present invention is a quadruple disk.

  A sample disk C605 and a sample disk D606 are further added to the configuration of FIG. 2 on the inner peripheral side, and bar code readers 607 and 608 for reading the samples in the respective disks are similarly arranged. By arranging the barcode reader in this way, conventionally, reading from the outside of the circumference was fundamental, but the barcode can also be read inside the circumference, and the sample position is set to 100 as shown in FIG. Even if it is mounted individually, it can be realized in a space-saving manner without changing the size of the sample disk of FIG. In addition to the above, it is also possible to read the barcodes of all samples at any time regardless of the state of the apparatus such as sampling.

  In addition, even when expanded to a triple disc, etc., by installing two barcode readers that read two discs adjacent to the sample disc B202 located between both discs, the barcodes of all the samples are the same as above. Can be read at any time regardless of the state of the apparatus such as sampling. In addition, if the barcode reader installed here is configured to be able to switch reading in both directions, one barcode reader may be installed, and the number of barcode readers is not particularly limited.

  In the conventional automatic analyzer, as described above, since the barcode reader is arranged outside or inside the circumference, the double concentric disk structure of the outer circumference / inner circumference is changed to a triple or more concentric disk structure. When expanded, it was difficult to read the barcode of the sample on the sandwiched circumference. In order to expand the number of specimens installed, the number of specimens that can be installed was expanded by increasing the circumference of the disk while maintaining a double concentric disk structure, but this increases the installation area of the device. was there. In view of the fact that the time required for the rotation operation to move the next sample during sampling of the sample is becoming shorter, if the circumference of the disk is increased as described above, the sample can be moved in time. There was a possibility that it could not be done.

  There are also devices that can read barcodes on a sample on a double concentric disk by arranging the positions in the disk in a staggered manner so that the barcode of the sample does not overlap the barcode reader. As the disk structure increases from double to triple, it is necessary to arrange positions at intervals for reading bar codes of other circumferences, and the number of samples that can be set does not dramatically improve. In addition, when the number of samples installed is increased by narrowing the interval between samples, there is a high risk that the barcodes of other samples will be erroneously read and sample misplacement will occur.

  In this embodiment, by installing a barcode reader on each disk of the double concentric disk, the number of samples that can be installed in the disk is expanded, and the barcode is read and processed at an arbitrary timing. Ability can be improved.

  In addition, because the size of the disk can be reduced while maintaining the number of samples that can be installed, the rotation time for moving the next sample can also be shortened, and it can also be installed in analyzers with high analytical processing capabilities. Is possible.

  As another embodiment of the present invention, a case will be described in which a function for assisting input of a barcode of a sample is provided in advance.

In a general automatic analyzer, in order to start measurement, it is necessary to first register a sample using the operation screen 1-23. In the case of operation using a barcode, a barcode is provided for each sample. It is necessary to input. As this input means, generally, means for manually registering using a keyboard, or means for reading and inputting a barcode of a sample with an attached handy type barcode reader is used. However, in the case of manual input, it takes time to input a large number of sample barcodes at the same time, and there is a possibility of being registered erroneously.
Further, if the attached handy type barcode reader is used, it is possible to simplify the input because it is held over the sample, but it is necessary to purchase, and it takes time and effort to hold the sample with the handy barcode reader every time the sample is installed.

  According to the present embodiment, since the barcodes of all the installation positions can be read at any time regardless of whether the sample is sampled or not, the sample is installed in an empty position before the sample is registered, By instructing “code acquisition”, it is possible to provide a function for automatically inputting the read barcode and the installed position.

  FIG. 7 shows a sample registration preparation flow and screen example when this method is used.

  In this method, unlike the conventional sample registration, the user first installs the sample at a vacant position. At this time, the sample list screen 704 is blank except for the sample at position 1 currently being sampled.

  Next, using a screen such as 701 shown in FIG. 7, a “barcode capture start” button 702 for instructing the capture of the barcode of the sample is pressed. When the apparatus recognizes that the “barcode acquisition start” button 702 has been pressed, the apparatus performs the operations shown in FIGS. 3 and 4 even during sample sampling, and immediately starts the barcode reading operation. At this time, if the designated area 703 for the start position and the end position is provided, the user can designate the range of the position where the sample is set, and the number of samples read by the barcode taking operation can be reduced. It is also possible to shorten the operation time.

  When the barcode loading operation of the apparatus is completed, a screen in which the read barcode and installation position are input is displayed on the sample registration screen 704. Thus, the user can complete the preparation for sample registration without inputting a barcode simply by selecting a sample, opening the measurement request registration screen 705, and selecting a measurement item.

  As a result, the time to input the barcode is reduced, the preparation time until the measurement is started can be shortened, and the sample where the barcode reading error occurred at this point can be identified and dealt with. Can be started, so the user can start with peace of mind.

  According to this embodiment, it is possible to read the barcode of the input sample at any time regardless of the sampling state of the sample, and without inputting the barcode information for each sample to the apparatus when registering the sample. The device realizes the function of reading the barcode and assisting the input. As a result, it is possible to reduce the trouble of manually inputting a bar code as in the prior art, and it is possible to prevent a delay in reporting measurement results by eliminating input errors.

  As another embodiment of the present invention, a function of accurately monitoring the sample installation state in the sample disk will be described.

  For example, in the sample disk of FIG. 2, in the situation where sampling is performed from the sample setting position 1 on the sample disk A 201 as shown in FIGS. 3 and 4, the sample disk B 202 can freely operate. In this case, the sample disk B202 is rotated one position at a time, and the barcodes of the specimens that have reached the reading positions of the barcode readers 203 and 204 on both disks are read, so that all of the sample disks A201 and B202 are installed. The installation status of the 62-position sample can be grasped.

  In addition, after completion of sampling at the sample setting position 1 on the sample disc A201, even if the sampling is switched from the sample setting position on the sample disc B202 to the next sampling, the sample disc A201 is moved to one position from the position following the completion of reading. The reading operation can be continued by switching to the operation of rotating each time.

  As described above, the apparatus performs the above-described operations automatically and regularly, so that the status of the sample installed on the sample disk can be accurately and sequentially updated based on the barcode information. It becomes possible. Thereby, the user can grasp the erection state of the sample in the sample disk based on the information obtained by the above operation, and can expect improvement in usability.

  In addition, by storing the barcode read in the above operation, it is possible to collate the barcode read in the previous operation with the barcode information read in the current operation. Mistakes can also be reduced.

  For example, if a sample that has been analyzed is installed at a certain position, the barcode of the sample exists at the previous operation, and there is no sample barcode at the current operation, It can be recognized that the sample has been removed. For this reason, if a position is waiting for sampling and it is detected that there is no barcode for the sample during this operation, there is a possibility that the user may have removed the sample for confirmation and forgot to install it. It can be considered that a mistake such as “the user mistakenly removed the sample after analysis” has occurred. For example, when it is detected that the barcode of a sample at one position is installed at another position as a result of reading all positions, `` When the user removes the sample and installs it again, It can be considered that a mistake such as “installed in the wrong position” has occurred.

  When such a human error is detected, it is possible to deal with the error before sampling by notifying the user of the alert. After the measurement or during the measurement, the error is noticed and the measurement is performed again. It is possible to shorten the time until the redo is performed and to avoid delay in reporting the measurement results. As for the means for notifying the user, the alarm screen generally used in the automatic analyzer may be used for notification, or the screen for monitoring the sample disk indicates an abnormality with identification information such as color. Further, there may be a function that can change the notification method on the setting screen, and there is no particular limitation.

  In the above description, the apparatus is described as being automatically performed regularly. However, a case where the operation is performed according to a request from the user may be used.

  According to the present embodiment, it is not read (NO) in the determination 501 in FIG. 5 described in [Embodiment 1], “Are the sample that should be on the barcode reader of the partner disk already read?” Therefore, it is possible to make the check operation for preventing sample mistakes function effectively.

  In addition, by utilizing the fact that the barcode of the loaded sample can be read at any time regardless of the sampling status of the sample, the barcodes of all installation positions can be driven by driving the disk that is not sampling the sample. A function to read periodically can be provided. With this function, the installation status of the sample in the disc can be updated sequentially, the sample waiting for sampling has been removed, or the user has taken out the sample and confirmed the position to install it It is possible to reduce human error by extracting the abnormalities.
