  The present invention relates to a urine analyzer and a urine sample information processing apparatus that perform urine qualitative measurement and urine sediment measurement.

  A urine analyzer that performs urine qualitative measurement and urine sediment measurement is known. In such a urine analyzer, there is one in which a cross check is performed in which a measurement result is mutually checked with respect to measurement items that are related to each other among urine qualitative measurement items and urine sediment measurement items (eg, patent References 1 and 2).

JP 2006-98219 A Japanese Patent Laid-Open No. 9-218197

  Urine sediment is often measured only when it is determined that further examination is necessary as a result of urine qualitative measurement. For this reason, in urinalysis, urine qualitative measurement is first performed, and then urine sediment is measured. In addition, since the cross check cannot be executed unless both the urine qualitative and urinary sediment measurement results are available, for example, as described in Patent Document 1, after the urinary sediment measurement results are obtained, automatic Cross check was executed.

  However, in actual inspection work, urine qualitative measurement may be performed after urine sediment measurement. In this case, in the conventional urine analyzer, the cross check is not automatically executed, which places a burden on the user.

  The present invention has been made in view of the above problems, and a urine analyzer and a urine analyzer that can automatically perform a cross check regardless of which of urine qualitative measurement and urine sediment measurement is performed first. An object is to provide a sample information processing apparatus.

A first aspect of the present invention relates to a urine analyzer. The urine analyzer according to this aspect includes a qualitative measurement unit that measures a measurement item related to urine qualification, a sediment measurement unit that measures a measurement item related to urine sediment, and a qualitative measurement obtained by measuring a sample using the qualitative measurement unit. When the sample is measured by the qualitative measurement unit and the storage unit that stores the result and the sediment measurement result obtained by measuring the sample by the sediment measurement unit together with the identification information of the sample, the qualitative measurement result is obtained If the sediment measurement result of the sample having the same identification information as the sample to be measured is stored in the storage unit, a cross check between the qualitative measurement result and the sediment measurement result is executed, and the sample is detected by the sediment measurement unit. is measured, when the sediment measurement result is obtained, if qualitative measurement result of the sample having the same identification information as the analyte to be measured if stored in the storage unit, the sediment measurement results and the qualitative And a control unit for performing a crosscheck between the constant result.

  According to the urine analyzer according to this aspect, the cross check can be executed regardless of which of the measurement by the qualitative measurement unit and the measurement by the sediment measurement unit is performed first. Thereby, a user's burden can be reduced.

In the urine analyzer according to this aspect, when the sample is measured by the qualitative measurement unit and a qualitative measurement result is obtained, the control unit has the same identification information as the sample to be measured stored in the storage unit If the sediment measurement result is obtained within a predetermined time, a cross check between the qualitative measurement result and the sediment measurement result is performed, and the specimen is measured by the sediment measurement unit, and the sediment measurement result is obtained. If a qualitative measurement result for a sample having the same identification information as the measurement target sample stored in the storage unit is obtained within a predetermined time, a cross check between the sediment measurement result and the qualitative measurement result is performed. May be configured to perform. In this way, since the cross check is not executed based on the measurement result performed on the specimen that has deteriorated over time, the accuracy of the cross check can be maintained high.

  In this case, the urine analyzer according to this aspect may be configured to further include a setting unit that sets the predetermined time. In this way, since the user can set a predetermined time via the setting means, it is possible to set a time range in which cross check is performed in accordance with an allowable range for each user with respect to the degree of specimen deterioration. Become.

  In this case, the predetermined time may be configured so that a default value of 15 minutes to 60 minutes is set. If the predetermined time is set to 15 minutes or more, the reagent used in the sediment measurement unit runs out, and even if it takes 10 minutes from the qualitative measurement to the sediment measurement, for example, cross check Is executed. In addition, when the predetermined time is set to 60 minutes or less, it is possible to prevent a long period of time from passing through the sediment measurement and executing a low-accuracy cross check for a specimen in which bacteria are generated. Accordingly, the time range in which the cross check is performed is appropriately 15 minutes or more and 60 minutes or less. If such a predetermined time is set in advance, the user does not need to set the predetermined time. Further, the predetermined time can be easily adjusted using the predetermined time set as the default value as a guide.

In the urine analyzer according to this aspect, the storage unit combines the first database that holds the qualitative measurement result, the second database that holds the sediment measurement result, and the qualitative measurement result and the sediment measurement result. A third database that stores set information; and when the sample is measured by the qualitative measurement unit and a qualitative measurement result is obtained, the control unit stores the same identification information as the sample to be measured in the second database If the sediment measurement result of the sample is stored, set information for combining the obtained qualitative measurement result and the stored sediment measurement result is stored in the third database, and the sample measurement unit performs the sample measurement. There is measured, when the sediment measurement result is obtained, if it is qualitative measurement result is stored in the specimen of the same identification information as the analyte to be measured in the first database, resulting et al And the group information for combining the results sediment measurement results and the stored qualitative measurements may be configured to store in said third database.

  In this case, the control unit may be configured to further store the result of the cross check performed on the combined qualitative measurement result and sediment measurement result in the third database.

  The urine analyzer according to this aspect may further include a transport unit that transports the sample in the order from the qualitative measurement unit to the sediment measurement unit.

A second aspect of the present invention relates to a urine sample information processing apparatus. The urine sample information processing apparatus according to this aspect identifies a sample using the qualitative measurement result obtained by measuring the sample by the qualitative measurement unit and the sediment measurement result obtained by measuring the sample by the sediment measurement unit. When the sample is measured by the storage unit storing the information and the qualitative measurement unit and the qualitative measurement result is obtained, the sediment measurement result of the sample having the same identification information as the sample to be measured is stored in the storage unit. For example, when the cross-check between the qualitative measurement result and the sediment measurement result is performed and the sample is measured by the sediment measurement unit and the sediment measurement result is obtained, the sample having the same identification information as the sample to be measured is obtained. If a qualitative measurement result is stored in the storage unit, a control unit that executes a cross check between the sediment measurement result and the qualitative measurement result is provided.

  According to the urine analyzer according to this aspect, the same effects as those of the first aspect can be obtained.

  As described above, according to the present invention, there is provided a urine analyzer and a urine sample information processing apparatus capable of automatically performing a cross check regardless of which of urine qualitative measurement and urine sediment measurement is performed first. Can be provided.

  FIG. 6 is a flowchart showing merge processing by the information processing apparatus 40 during qualitative measurement processing.

  When the CPU 401 of the information processing apparatus 40 transmits a qualitative order inquiry to the host computer 60 based on the qualitative order inquiry received from the urine qualitative measurement unit 10, until the inquiry result (qualitative order) is received from the host computer 60. The process is put on standby (S101). When the CPU 401 receives the qualitative order (S101: YES), the CPU 401 transmits the received qualitative order to the urine qualitative measurement unit 10, and the measurement by the urine qualitative measurement unit 10 is necessary based on the necessity of measurement included in the qualitative order. It is determined whether or not there is (S102).

  When measurement by the urine qualitative measurement unit 10 is necessary (S102: YES), the CPU 401 creates a new record in the qualitative DB (S103). In this new record, a unique number is stored in the number item, a sample number included in the qualitative order is stored in the sample number item, and items other than these two items are empty.

Subsequently, the CPU 401 causes the process to wait until the measurement by the urine qualitative measurement unit 10 is completed and a qualitative measurement result is received from the urine qualitative measurement unit 10 (S104). Upon receiving the qualitative measurement result (S104: YES), the CPU 401 stores the received qualitative measurement result in the qualitative DB (S105). That is, the measurement date and time included in the received qualitative measurement result is stored in the measurement date and measurement time of the record created in S103. The corresponding measurement result included in the received qualitative measurement result is stored in the measurement result item of the record created in S103.

  Subsequently, the CPU 401 determines whether the sediment measurement result within the set time is stored in the sediment DB, which is the same sample number as the sample number included in the received qualitative measurement result and goes back from the current time. Is determined (S106). The set time will be described later with reference to FIGS. 9A and 9B. If there is such a sediment measurement result (S106: YES), the process proceeds to S107. If there is no such sediment measurement result (S106: NO), the process proceeds to S111.

  If YES is determined in S106, the CPU 401 performs a cross check from the received qualitative measurement result and the latest sediment measurement result among the sediment measurement results (S107). For the cross check determination, the cross check table shown in FIG. 5B is used.

  Subsequently, the CPU 401 stores the link to the qualitative measurement result, the link to the latest sediment measurement result, and the cross check result performed in S107 in the merge DB (S108). That is, the CPU 401 creates a new record in the merge DB, and the time when this new record is created is stored in the measurement date and measurement time of this record. In addition, the qualitative number item and the sediment number item of this record include the number of the qualitative DB number item indicating the qualitative measurement result used for the cross check and the sediment DB indicating the measurement result of the sediment used for the cross check, respectively. The number of the number item is stored. In addition, the cross check result item of this record appropriately stores the cross check result.

  Next, when there is no need for measurement by the urine qualitative measurement unit 10 (S102: NO), the CPU 401 sets the sample number that is the same as the sample number included in the received qualitative measurement result and is retroactive from the current time. It is determined whether or not the sediment measurement results within the time are stored in the sediment DB (S109). If there is such a sediment measurement result (S109: YES), the process proceeds to S110. If there is no such sediment measurement result (S109: NO), the process proceeds to S111.

  If it is determined YES in S109, the CPU 401 stores a link to the latest sediment measurement result among the sediment measurement results in the merge DB (S110). That is, the CPU 401 creates a new record in the merge DB, and the time when this new record is created is stored in the measurement date and measurement time of this record. In the sediment number item of this record, the number of the sediment DB number item indicating the latest sediment measurement result among such sediment measurement results is stored. Further, 0 is stored in the qualitative number item and the cross check result item of this record.

  When the shutdown processing of the information processing apparatus 40 is not performed by the user (S111: NO), the CPU 401 repeats the processing of S101 to S110, and when the shutdown processing is performed (S111: YES), the CPU 401 ends the processing.

  FIG. 7 is a flowchart showing merge processing by the information processing apparatus 40 during sediment measurement processing.

  When the CPU 401 of the information processing apparatus 40 transmits a sediment order inquiry to the host computer 60 based on the sediment order inquiry received from the urine sediment measurement unit 20, until the inquiry result (sediment order) is received from the host computer 60. The process is put on standby (S201). When the CPU 401 receives the sediment order (S201: YES), the CPU 401 transmits the received sediment order to the urine sediment measurement unit 20, and the measurement by the urine sediment measurement unit 20 is necessary based on the necessity of measurement included in the sediment order. It is determined whether or not there is (S202).

  When measurement by the urine sediment measurement unit 20 is necessary (S202: YES), the CPU 401 creates a new record in the sediment DB (S203). In this new record, a unique number is stored in the number item, a sample number included in the sediment order is stored in the sample number item, and items other than these two items are empty.

  Subsequently, the CPU 401 waits for processing until the measurement by the urine sediment measurement unit 20 is completed and the measurement result of sediment is received from the urine sediment measurement unit 20 (S204). When the CPU 401 receives the sediment measurement result (S204: YES), the CPU 401 stores the received sediment measurement result in the sediment DB (S205). That is, the measurement date and time included in the received sediment measurement result is stored in the measurement date and measurement time of the record created in S203. Further, the corresponding measurement result included in the received sediment measurement result is stored in the measurement result item of the record created in S203.

  Subsequently, the CPU 401 determines whether or not the qualitative measurement result within the set time is stored in the qualitative DB, which is the same specimen number as the specimen number included in the received sediment measurement result, and goes back from the current time. Is determined (S206). If there is such a qualitative measurement result (S206: YES), the process proceeds to S207. If there is no such qualitative measurement result (S206: NO), the process proceeds to S211.

  If YES is determined in S206, the CPU 401 performs a cross check from the latest qualitative measurement result among the qualitative measurement results and the received sediment measurement result (S207). For the cross check determination, the cross check table shown in FIG. 5B is used.

  Subsequently, the CPU 401 stores the link to the latest qualitative measurement result, the link to the sediment measurement result, and the cross check result performed in S207 in the merge DB (S208). That is, the CPU 401 creates a new record in the merge DB, and the time when this new record is created is stored in the measurement date and measurement time of this record. In addition, the qualitative number item and the sediment number item of this record include the number of the qualitative DB number item indicating the qualitative measurement result used for the cross check and the sediment DB indicating the measurement result of the sediment used for the cross check, respectively. The number of the number item is stored. In addition, the cross check result item of this record appropriately stores the cross check result.

  Next, when there is no need for measurement by the urine sediment measurement unit 20 (S202: NO), the CPU 401 sets the sample number that is the same as the sample number included in the received sediment measurement result, retroactively from the current time. It is determined whether or not the qualitative measurement results within the time are stored in the qualitative DB (S209). If there is such a qualitative measurement result (S209: YES), the process proceeds to S210. If there is no such qualitative measurement result (S209: NO), the process proceeds to S211.

If it is determined YES in S209, the CPU 401 stores a link to the latest qualitative measurement result among such qualitative measurement results in the merge DB (S210). That is, the CPU 401 creates a new record in the merge DB, and the time when this new record is created is stored in the measurement date and measurement time of this record. In addition, the qualitative number item of this record stores the number of the qualitative DB number item indicating the latest qualitative measurement result among the qualitative measurement results. Further, 0 is stored in the sediment number item and the cross check result item of this record.

  When the shutdown processing of the information processing apparatus 40 is not performed by the user (S211: NO), the CPU 401 repeats the processing of S201 to S210, and when the shutdown processing is performed (S211: YES), the CPU 401 ends the processing.

  FIG. 8A is a diagram illustrating an example of merge processing.

  In FIG. 8A, the vertical axis indicates time, and indicates that the information processing apparatus 40 has received qualitative measurement results A1 and A2 and sediment measurement results B1 and B2 along the time axis. . Note that these measurements are all performed on the same sample, and the date and time when the measurement was performed and the date and time when the information processing apparatus 40 received the measurement result are the same. The time difference obtained between the measurement result A1 and the measurement result B1 is Δt1, the time difference obtained between the measurement result A1 and the measurement result B2 is Δt2, and the time difference obtained between the measurement result B2 and the measurement result A2 is Δt3. Suppose that Further, Δt1 and Δt2 are shorter than the set time, and Δt3 is longer than the set time.

  The measurement result A1 and the measurement result B1 are obtained when the sample container 51 containing the sample is held in the sample rack 50 and first transported through the transport path by the transport unit 30. The measurement result B2 is obtained when the sample container 51 containing the sample is held in the sample rack 50 and transported through the transport path by the transport unit 30 for the second time. In this case, an order for performing only urine sediment measurement on the specimen is registered in the host computer 60. The measurement result A2 is obtained when the sample container 51 containing the sample is held in the sample rack 50 and transported through the transport path by the transport unit 30 for the third time. In this case, an order for performing only urine qualitative measurement on the sample is registered in the host computer 60.

  Referring to FIG. 8A, if it is determined that qualitative measurement is necessary as a result of the qualitative order inquiry to the host computer 60, qualitative measurement is performed on this sample, and measurement result A1 Is obtained. At the time when the measurement result A1 is obtained, the sediment of the same specimen has not been measured before that, so the cross check is not performed and the record is not added to the merge DB based on the measurement result A1.

  Subsequently, a sediment order inquiry is made to the host computer 60 for this sample. When the host computer 60 determines that sediment measurement is necessary based on the measurement result A1, an order for measuring sediment for this sample is transmitted to the information processing apparatus 40. Thereby, the sediment is measured and the measurement result B1 is obtained. When the measurement result B1 is obtained, the measurement result A1 is obtained by Δt1 before, so a cross check is performed based on the measurement results A1 and B1, and a record is added to the merge DB.

Subsequently, in order to perform only sediment measurement again, the user sets a qualitative order and sediment order for the host computer 60 so that only sediment measurement is performed for this specimen. Then, the user sets this sample again in the right tank region 31a and starts measurement. Thereafter, the host computer 60 is inquired about the qualitative order and the sediment order. As a result, the qualitative measurement is not performed on this specimen, only the sediment measurement is performed, and the measurement result B2 is obtained. When the measurement result B2 is obtained, the measurement result A1 is obtained by Δt2 before, so a cross check is performed based on the measurement results A1 and B2, and a record is added to the merge DB. Thereby, in the merge DB, both records based on the measurement results A1 and B1 and records based on the measurement results A1 and B2 are stored.

  Subsequently, the user sets a qualitative order and a sediment order in the host computer 60 in order to perform only the qualitative measurement again. As a result of inquiring the host computer 60 for the qualitative order, this sample is subjected to qualitative measurement, and a measurement result A2 is obtained. Next, the host computer 60 is inquired about the sediment order, and a response is made that the sediment is not measured for this specimen. As a result, sediment measurement is skipped. When the measurement result A2 is obtained, the measurement result B2 is obtained before Δt3 which is larger than the set time, so the cross check is not performed based on the measurement results A2 and B2, and No records are added.

  FIG. 8B shows a case where it is determined that the sediment measurement is unnecessary as a result of the inquiry of the sediment order to the host computer 60 at the timing when the measurement result B1 of FIG. 8A is obtained. FIG.

  In this case, when it is determined that the sediment measurement is unnecessary, the measurement result A1 is obtained by Δt1 before, so the record is added to the merge DB based only on the measurement result A1. At this time, in the record added to the merge DB, as shown in FIG. 5A, 0 is stored in the sediment number item and all the cross check result items.

  FIG. 9A is a flowchart showing setting processing by the information processing apparatus 40.

  The CPU 401 of the information processing apparatus 40 determines whether an instruction to display the service setting screen D1 is given by the user via the input unit 410 (S301). When an instruction to display the service setting screen D1 is given (S301: YES), the CPU 401 reads setting contents of setting items described later from the hard disk 404 and displays the service setting screen D1 on the display unit 420 (S302).

  FIG. 9B shows the service setting screen D1. The service setting screen D1 has a setting item display area D11, an input area D12, an OK button D13, and a cancel button D14.

  In the setting item display area D11, a plurality of setting items of the information processing apparatus 40 that can be changed are displayed. The setting items displayed in the setting item display area D11 include setting times used in S106 in FIG. 6 and S206 in FIG. When the user clicks a setting item in the setting item display area D11, the clicked item is highlighted as shown in FIG. 9B, and the setting contents of this setting item are displayed in the input area D12. The setting items highlighted in FIG. 9B are items relating to the setting time used in S106 of FIG. 6 and S206 of FIG. The user can change the content of the setting item by rewriting the content displayed in the input area D12 and clicking the OK button D13.

Here, the default value (initial state value) of the set time in the present embodiment is set to 30 (minutes). It is desirable that the default value of the set time is set to such an extent that a cross check is performed even if the reagent or test paper is exchanged between the measurement of the urine qualitative measurement unit 10 and the measurement of the urine sediment measurement unit 20. . That is, it is desirable that the time is set to be longer than the time (for example, 15 minutes) assumed to be required for replacing the reagent and the test paper. Moreover, it is desirable that the default value of the set time is set to such an extent that the accuracy of the measurement result is maintained. In other words, the measurement results of specimens that have deteriorated over time are considered to have low accuracy. Therefore, the accuracy of the measurement results can be maintained so that cross-checks are not performed based on such measurement results. It is desirable to set it below (for example, 60 minutes).

  If the set time is set to 0, it is always determined as NO in S106 of FIG. 6 and S206 of FIG. 7, so that the cross check is not performed.

  Returning to FIG. 9A, when the service setting screen D1 is displayed (S302), the CPU 401 of the information processing apparatus 40 waits for processing until the OK button D13 or the cancel button D14 is clicked. When the OK button D13 is clicked (S303: YES), the CPU 401 stores the setting contents rewritten by the user in the hard disk 404 (S304). When the cancel button D14 is clicked (S303: NO, S305: YES), the process proceeds to S306.

  If the shutdown processing of the information processing apparatus 40 is not performed by the user (S306: NO), the CPU 401 repeats the processing of S301 to S305, and if the shutdown processing is performed (S306: YES), the processing ends.

  FIG. 10 is a diagram showing a result display screen D2 for displaying the result of measurement by the urine analyzer 1. The result display screen D2 is displayed on the display unit 420 according to a display instruction from the user.

  The result display screen D2 has a list display area D21, switching tabs D22a to D22d, a patient information display area D23, and a display button D24.

  The list display area D21 is configured so that the display is switched according to the selected switching tab among the switching tabs D22a to D22d. FIG. 10 shows a state where the switching tab D22c is selected and merge data based on the merge DB is displayed. In the list display area D21 in this state, a type item, a qualitative item, a sediment item, a sample number item, a measurement date item, a measurement time item, and a plurality of measurement result items are displayed.

In the type item, a character string “FIN” or “CHK” is displayed. When “FIN” is displayed, the merge data shown in this line indicates that there are no check items in the cross check result items that are considered errors (all 0). When “CHK” is displayed, the merge data shown in this line indicates that there is a check item that is regarded as an error in the cross check result item.

  In the qualitative item and the sediment item, information on measurement by the urine qualitative measurement unit 10 and the urine sediment measurement unit 20 is displayed, respectively. When “Comp” is displayed in these items, the merge data shown in this line indicates that the measurement result is normally obtained.

  In the sample number item, the sample number that is the source of the merge data shown in this row is displayed. In the measurement date item and the measurement time item, the measurement date item and the measurement time item of the merge DB are displayed. The measurement result items include all qualitative measurement items and all sediment measurement items, and the qualitative measurement results and sediment measurement results are displayed.

  When the switching tabs D22a to D22c are clicked, the list display area D21 displays qualitative measurement results based on the qualitative DB, sediment measurement results based on the sediment DB, and merge data based on the merge DB, respectively. . When the switching tab D22d is clicked, all the information displayed when the switching tabs D22a to D22c are clicked is displayed in the list display area D21.

In the patient information display area D23, patient information obtained from the sample number of the line clicked in the list display area D21 is displayed. When merge data is displayed in the list display area D21 as shown in FIG. 10, when a line in the list display area D21 is clicked and the display button D24 is clicked in a highlighted state as shown, Details of the merge data shown in this row are displayed on the merge data display screen D3.

  FIG. 11 is a diagram showing a merge data display screen D3. Note that the merge data on the fifth line from the top of the list display area D21 in FIG. 10 is displayed on the merge data display screen D3 in FIG.

  The merge data display screen D3 has a specimen information display area D31, a patient information display area D32, a qualitative result display area D33, sediment result display areas D34 and D35, and a cross check result display area D36.

  In the sample information display area D31, information on the sample that is the basis of the measurement result displayed on the merge data display screen D3 is displayed. In the patient information display area D32, patient information obtained by collecting this sample is displayed.

  A list of qualitative measurement results is displayed in the qualitative result display area D33. In the sediment result display area D34, a list of sediment measurement results is displayed. In the sediment result display area D35, the sediment measurement result is displayed as a scattergram. In the cross check result display area D36, the result of the cross check performed on the merge data is displayed. If there is no cross check that is an error, the cross check result display area D36 is blank.

  FIG. 12 is a diagram showing a merge data display screen D3 when displaying merge data consisting only of qualitative measurement results. Note that the merge data on the fourth line from the top of the list display area D21 in FIG. 10 is displayed on the merge data display screen D3 in FIG.

  Unlike the merge data display screen D3 shown in FIG. 11, the merge data display screen D3 in this case does not include sediment measurement results, so the sediment result display areas D34 and D35 are displayed in gray. Since no cross check is performed, the cross check result display area D36 is also displayed in gray.

  When displaying merge data consisting only of sediment measurement results, sediment measurement results are displayed in sediment result display areas D34 and D35, and qualitative result display area D33 and cross check result display area D36 are displayed in gray. Is done.

  As described above, according to the present embodiment, when qualitative measurement results are obtained, if the same specimen number and the sediment measurement results within the set time are stored in the sediment DB, these measurement results are included in the measurement results. A cross check is performed based on this. Further, when the sediment measurement result is obtained, if the qualitative measurement result within the set time is stored in the qualitative DB with the same specimen number, a cross check is performed based on these measurement results. As a result, the cross check can be executed regardless of which of the measurement by the urine qualitative measurement unit 10 and the measurement by the urine sediment measurement unit 20 is performed first.

  Further, when a qualitative measurement result is obtained, if the sediment measurement result stored in the sediment DB is obtained within the set time, a cross check is performed. Further, when the sediment measurement result is obtained, if the qualitative measurement result stored in the qualitative DB is obtained within the set time, a cross check is performed. Thereby, since the cross check is not executed based on the measurement result performed on the specimen that has deteriorated over time, the accuracy of the cross check can be maintained high.

  As mentioned above, although embodiment of this invention was described, embodiment of this invention is not limited to these.

  For example, in the above embodiment, whether or not the measurement in the urine qualitative measurement unit 10 and the urine sediment measurement unit 20 is performed is determined based on the qualitative order and the sediment order transmitted from the host computer 60, respectively. However, the present invention is not limited to this, and the user may determine whether or not the urine qualitative measurement unit 10 and the urine sediment measurement unit 20 perform measurement.

  In this case, the user makes a setting for the information processing apparatus 40 via the input unit 410 (see FIG. 3) of the information processing apparatus 40 such that the measurement is performed without inquiring the host computer 60 for an order. Do. At this time, the user also sets which of urine qualitative measurement and urine sediment measurement is performed, and what items are measured. This setting is performed for each sample rack 50, not for each sample. As a result, only one of the urine qualitative measurement and the urine sediment measurement is performed for each sample rack 50. After such setting, when the user starts the measurement by setting the sample rack 50 holding the sample container 51 in the right tank region 31a, either urine qualitative measurement or urine sediment measurement is performed on the sample. Only the measurement is performed.

  In addition, the user can perform only the measurement of the urine sediment by setting the information processing apparatus 40 so that the manual measurement by the urine sediment measurement unit 20 is performed. In this case, the sample container 51 is set by the user at a set position for manual measurement provided in front of the urine sediment measurement unit 20. When manual measurement is executed, the nozzle of the urine sediment measurement unit 20 moves to this set position, and the sample is aspirated from this position. As a result, measurement by the urine sediment measurement unit 20 can be performed with priority over other samples on the transport path 31.

  As described above, in the urine analyzer 1, since measurement can be performed by only one of the urine qualitative measurement unit 10 and the urine sediment measurement unit 20, the user appropriately performs urine qualitative measurement and urine sediment measurement. It can be carried out. That is, after the sample is measured by the urine sediment measuring unit 20, the sample can be measured by the urine qualitative measuring unit 10. Further, as shown in the above embodiment, after the measurement is sequentially performed by the urine qualitative measurement unit 10 and the urine sediment measurement unit 20, the measurement can be further performed by the urine qualitative measurement unit 10 or the urine sediment measurement unit 20. . Also in such a case, as in the above embodiment, the qualitative measurement result and sediment measurement result are stored in the qualitative DB and sediment DB, respectively, and the merge processing shown in FIGS. 6 and 7 is performed. Also good. In this case, S101 in FIG. 6 and S201 in FIG. 7 are omitted, and the determination in S102 in FIG. 6 and S202 in FIG. 7 is performed according to the setting from the user for the information processing apparatus 40 when processing the sample. Is called. In the case of manual measurement, since urine sediment is always measured, the determination in S202 of FIG. 7 is always YES. Therefore, in the case of manual measurement, the processing after S203 is performed.

  Moreover, in the said embodiment, although urine was illustrated as a measuring object, the blood can also be made into a measuring object. That is, the present invention can be applied to a sample analyzer that tests blood, and further, the present invention can be applied to a clinical sample analyzer that tests other clinical samples.

In the above embodiment, the measurement of the urine sediment measurement unit 20 is performed using a flow cytometer. However, the measurement is not limited to this, and the measurement of the urine sediment measurement unit 20 is performed by imaging a urine sample. This may be done by analyzing the sediment image. In this case, instead of the scattergram displayed in the sediment result display area D35 of FIGS. 11 and 12, a sediment result display area D35 ′ (see FIG. 13) including the captured sediment image may be displayed. good. Further, the sediment result display area D35 ′ may be displayed together with the scattergram displayed in the sediment result display area D35 of FIGS. As described above, when the sediment result display area D35 ′ is displayed, the user can compare the combination of the measurement results with the sediment image for the same sample, and can more appropriately evaluate the measurement result for the sample. it can.

  In the above embodiment, the merge DB stores the number of the number items of the qualitative DB and the sediment DB. However, the merge DB is not limited to this, and the merge DB includes the qualitative measurement result and sediment measurement. The result may be stored directly. In addition, information such as qualitative data to be combined and sediment measurement date and time may be stored in the merge DB. Information stored in the merge DB in such a form also corresponds to “group information”. That is, the “combination information” described in the claims may be any information as long as it can extract the qualitative measurement result and the sediment measurement result combined with each other. In this way, instead of the number items of the qualitative DB and sediment DB in FIG. 5A, when storing the qualitative and sediment measurement results and measurement date and time, from the combination of the measurement results and the measurement date and time, Cannot identify the sample to be combined. Therefore, in these cases, it is necessary to include the sample number in each record of the merge DB.

  In the above embodiment, when the qualitative measurement result is obtained, if the sediment measurement result stored in the sediment DB is not obtained within the set time, the set information is stored in the merge DB. In addition, when the sediment measurement result is obtained, the combination information is not stored in the merge DB unless the qualitative measurement result stored in the qualitative DB is obtained within the set time. However, instead of this, when the qualitative measurement result is obtained, if the sediment measurement result is stored in the sediment DB, the obtained qualitative result is obtained regardless of the time when the sediment measurement result is acquired. The set information may be created from the measurement result and the latest sediment measurement result stored in the sediment DB, and the created set information may be stored in the merge DB. Similarly, if the qualitative measurement results are stored in the qualitative DB when the sediment measurement results are obtained, the obtained sediment measurement results and qualitative results regardless of the time when the qualitative measurement results were acquired. The pair information may be created from the latest qualitative measurement result stored in the DB, and the created pair information may be stored in the merge DB.

  In addition, the embodiment of the present invention can be variously modified as appropriate within the scope of the technical idea shown in the claims.
