Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic analyzer, and more particularly to an automatic analyzer suitable for quality control when measuring the same item on a plurality of measurement channels.

[0002]

2. Description of the Related Art In an automatic analyzer, quality control is performed by measuring a quality control sample having a known concentration during sample measurement. A typical example is the xR control chart method. In this method, a quality control sample is measured during a daily inspection, and the average value (x) and the standard deviation (R) are used to determine whether the inspection is performed normally. In an automatic analyzer that dispenses a reagent and a sample into a reaction vessel and measures the reaction solution, generally, there is one path on the device from dispensing of the sample and the reagent to measurement of the reaction solution, and the measuring unit Quality control is performed for each.

In recent years, an increase in processing capacity has been demanded, and an automatic analyzer that performs measurement by connecting a plurality of the above automatic analyzers has been developed. In order to analyze a plurality of items at once, there is a method in which fixed measurement items that do not overlap with each other are assigned to each measurement unit, and a case in which a frequently requested item is measured by a plurality of measurement units. However, when the same item is measured by a plurality of measuring units, such measurement results are considered to be obtained from one device even if the measured measuring units are different. In the apparatus as well, quality control is performed for each measuring unit.

[0004]

The accuracy of each part of the apparatus, such as the dispensing of samples and reagents and the detection of signals from the reaction solution, affects the measured values. If some of the routes on the device are different, even if the same item is measured, the measurement data includes a difference derived from the route taken until the measurement was obtained. Thus, when measurement data of the same item is obtained through different paths, each path is called a measurement channel and distinguished.

When the same item is measured by connecting a plurality of automatic analyzers as described above, even if the measurement data of the quality control sample obtained from each measurement channel is within the quality control, each measurement channel When the data obtained from the data are combined into one and considered as the result obtained by one device, the measurement data includes the difference between the measurement channels, so the overall variation becomes large and the accuracy is not controlled, and the reliability of the inspection result May be impaired. Therefore, in such a case, in addition to the quality control in the individual measurement channels, the data of the quality control samples obtained from the respective measurement channels were obtained from one measurement channel together without discrimination. It is necessary to control the accuracy as in the case. The same applies to the case where the same item is measured on a plurality of measurement channels in one analyzer.

When an automatic analyzer having a plurality of measurement channels is connected to measure the same item on a plurality of measurement channels, data obtained by each automatic analyzer may be used in addition to the above-described accuracy control. It is necessary to manage the accuracy in the same way as in the case of obtaining from one measurement channel without discriminating between them. This is because both the connected automatic analyzers and individual automatic analyzers having a plurality of measurement channels can be considered as one automatic analyzer. Hereinafter, each connected automatic analyzer is referred to as an analysis module.

An object of the present invention is to provide an automatic analyzer suitable for improving the reliability of test results.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below. FIG. 1 shows an embodiment of the present invention. In FIG. 1, the analysis module 15-1 is provided with a sample input unit 20 for sending out a rack 2 on which a plurality of sample containers 1-1, 1-2,... ing. Through this transport path, the sample is transported to the sampling position of the analysis module 15-1. On the way, information on the quality control sample to be measured, such as the type and lot of the quality control sample, is registered in the apparatus from the barcode placed on the sample container by the barcode reader.

The reagent 4 is set on a reagent disk 5.
Information such as the type and lot of the reagent is also registered on the apparatus via the barcode. The dispensing of the sample and the reagent is performed by the dispensing probe 6. The dispensing probe 6 detaches a disposable tip from the tip every time dispensing. Unused chips are held on the rack 7. The thermostat 8 holds a plurality of reaction vessels 9-1, 9-2,. The reaction vessels are disposable, and unused reaction vessels are held on a rack 10. The movement of the reaction vessel and the chip is performed by the transfer mechanism 1
1 is performed. 1 chip and reaction vessel used
Discarded in several places. The reaction liquid is introduced into the detector in the detection unit 13-1 by the nozzle 12, and the light emission amount is detected. The reaction liquid after the measurement is collected in the waste liquid tank 14.

The analysis modules 15-1 and 15-2 include a transport path 18 for the sample and a transport path 1 for remeasurement of the sample.
9. The analysis module 15-2 is provided with a retest standby unit 21 and a sample collection unit 22 that are connected to the transport path 3 and a transport path 23 in which the transport direction of the sample is opposite. Other configurations are the same as those of the analysis module 15-1. The signals detected by the detection units 13-1 and 13-2 are converted into a density by the data processing unit 16.
This measurement result is output to the output unit 17.

Next, an example of the operation of measuring the quality control sample of the embodiment shown in FIG. 1 will be described. In this embodiment, the item A of the quality control samples a and b having different concentrations of the test substance contained in the sample containers 1-1 and 1-2 is measured. The sample containers 1-1 and 1-2 are installed on a sample transport rack 2. First, when the sample container 1-1 containing the quality control sample a is transported from the sample input unit 20 through the transport path 3 to the sampling position of the analysis module 15-1, the dispensing probe 6 is moved by the transport mechanism 11 to the tip. The disposable tip placed at the mounting position is attached to the tip, and the reagent and the sample are dispensed into the reaction container 9-1 placed at the dispensing position. The reaction container 9-1 into which the reagent and the sample have been dispensed is transferred onto the thermostat 8 by the transfer mechanism 11.

When the reaction of the first step is completed, the reagent 4 placed on the reagent disk 5 is dispensed into the reaction container 9-1 by the dispensing probe 6, and subsequently, stirring is performed. After the reaction, the reaction container 9-1 is transferred to the suction position of the nozzle 12 by the transfer mechanism 11. The reaction liquid in the reaction vessel 9-1 is introduced into the detector in the detection unit 13-1 by the nozzle 12, and light emission from the reaction liquid is detected. After the measurement of one sample, the inside of the detector is washed and prepared for the next measurement.

After the dispensing of the quality control sample a from the sample container 1-1 to the reaction container 9-1, the dispensing probe 6 replaces the tip at the tip, and transfers the sample of the sample container 1-2 transferred to the sampling position. Dispense the quality control sample b into the reaction vessel 9-2. The same processing as that of the reaction container 9-1 is sequentially performed on the reaction container 9-2.

The rack 2 sampled by the analysis module 15-1 is transferred to the analysis module 15-2 through the transfer path 18. In the analysis module 15-2, the measurement of the quality control sample is performed by the same operation as that of the analysis module 15-1. The rack 2 for which sampling has been completed is transported to the retest standby unit 21. Here, it waits for the measurement result to be output, and as a result, when re-measurement is required, it passes through the transport path 19 and enters the transport path 3 of the analysis module. When the re-measurement is unnecessary, the sample is collected by the sample collection unit 22. In the quality control sample measurement before the general sample measurement on that day, sampling of the general sample is started after the user issues an instruction to start the general sample measurement. When the quality control sample is measured during the measurement of the general sample, the general sample is sampled by the same operation following the sampling of the quality control sample.

All signals detected on the two measurement channels are collected by the data processing unit 16 and stored in the storage unit. The measurement data converted to the concentration in the calculation unit is for each measurement channel, and the measurement data from the two measurement channels are combined into one, and within each day of each quality control sample, statistical calculation is performed on the day difference data, The quality management information is output to the output unit 17.

FIG. 2 is a flow chart showing the procedure of intraday accuracy management information in the embodiment of FIG. 1, FIG. 3 is a flow of processing in each analysis module, and FIG. 3 is a flow of processing of measurement data obtained from each measurement channel. Is shown in FIG.

The analysis modules 15-1 and 15-2 have one measurement channel 13-1 and 13-2, respectively, and measure the item A respectively. Here, it is specified in advance that the same quality control sample is measured on measurement channels (hereinafter, 13-1 and 13-2 are referred to as measurement channels) represented by the detection units 13-1 and 13-2 (1).
9). Alternatively, in each measurement channel in which the item A is measured, the same quality control sample is measured without designation. When the measurement channel on which the quality control sample is measured is determined, first, the quality control sample is measured by the analysis module 15-1 (20).

According to the above description of the operation, when the item A of the quality control sample a is measured in the measurement channel 13-1 (2)
1), this measurement data is sent to the data processing unit 16 (22). Hereinafter, the flow of processing of the measurement data obtained from the measurement channel 13-1 will be described (FIG. 4). The average value and the standard deviation of the measurement item A of the quality control sample a in the measurement channel 13-1 are calculated for that day (23).
The average value and the standard deviation are obtained by equations (1) and (2), respectively.

[0022]

(Equation 1)

[0023]

(Equation 2)

Where n is the measurement channel 13- on that day.
The number of measurement data for item A of quality control sample a measured at 1 and xi represent individual data for item A of quality control sample a measured at measurement channel 13-1 on that day. It is determined whether the average value and the standard deviation calculated by the above equations satisfy the respective predetermined values (24).
When the predetermined value is satisfied, the measured data and the calculated value are printed out from the printer as an x control chart and a data list of the intraday data of the measurement channel 13-1, or a CR is output.
It is displayed and output on the T screen (25).

If the predetermined value is not satisfied, it is determined whether or not the lot of the quality control sample a and / or the lot of the reagent contain different measurement data (26). If all lots are the same, an alarm is output to the printer or CRT that the item A of the quality control sample a does not satisfy the predetermined value on the measurement channel 13-1 (2).
7) The measurement data and the calculated accuracy management information are printed out from a printer as a x-control chart and a data list of the intraday data of the measurement channel 13-1, or displayed and output on a CRT screen (25). At this time, for example, the quality management information that does not satisfy the predetermined value is output in a different color from the surroundings.

When the lots are different, the average value and the standard deviation of the data of the measurement channel are obtained for each lot (2
8) It is determined whether a predetermined value is satisfied. At this time, if the management average value and the management SD have been changed due to the change of the lot, it is determined whether the average value and the standard deviation obtained for each lot satisfy the respective management values (2.
9). When the value obtained for each lot satisfies a predetermined value, the measurement data and the calculated quality control information are printed out from the printer as an x control chart and a data list of the day data of the measurement channel 13-1, or are displayed on the CRT screen. (25). When the value obtained for each lot does not satisfy the predetermined value, an alarm is output to the printer or CRT that the item A of the quality control sample a does not satisfy the predetermined value on the measurement channel 13-1 (2).
7) The measurement data and the calculated accuracy management information are printed out from a printer as a x-control chart and a data list of the intraday data of the measurement channel 13-1, or displayed and output on a CRT screen (25). At this time, for example, the quality management information that does not satisfy the predetermined value is output in a different color from the surroundings.

[0027] Even when the average value and the standard deviation calculated without distinguishing the lots of the reagent or the quality control sample from the measurement data of the day satisfy a predetermined value, the average value and the standard deviation are calculated for each lot. You may display similarly.

In the measurement channel 13-1, a quality control sample
Subsequent to the measurement of the item A of the item a, the item A of the quality control sample b having a different concentration of the test substance is measured (30). This measurement data is sent to the data processing unit 16 (31), and the quality control sample a
The same processing as in the case (1) is performed (FIG. 4). Similarly to the measurement channel 13-1, the measurement for the item A of the quality control samples a and b is performed in the measurement channel 13-2 (32).

When the quality control information is calculated for each measurement channel, the measurement channels 13-1 and 13-2 are next calculated.
The analysis module 15-1 and the analysis module 15-2 were connected without distinguishing the measurement data for the item A of the quality control sample a.
The average value and the standard deviation of the day as one automatic analyzer are calculated. At this time, n in the equations (1) and (2) is the number of measurement data for the item A of the quality control sample a measured on the entire automatic analyzer connected to the analysis modules 15-1 and 15-2 on that day, xi Is the analysis module 15 for that day
5 shows individual data on item A of quality control sample a measured by the entire automatic analyzer connected to -1 and 15-2. The processing for the average value and the standard deviation calculated by the above equation is as shown in FIG.

Each predetermined value of the quality control used here is:
Based on initially registered information on the quality control sample to be measured, the quality control of one measurement channel and the quality control combining data from two measurement channels can be separately designated in advance. For the item A of the quality control sample b, separately from the quality control sample a, the quality control information of the entire automatic analyzer that combines the measurement data obtained for each measurement channel and the two measurement channels is calculated and displayed. (33).

In the embodiment of FIG. 1, when the measurement of the quality control samples a and b of the item A is completed and the quality control information and the judgment result are output, the measurement channel or the analysis module whose quality control information does not satisfy the predetermined value. It is determined whether or not there is (34), and if there is no measurement channel or analysis module that does not satisfy the predetermined value, it is determined whether or not the measurement is before the general sample measurement of the day (35). If the quality control sample measurement is being performed during the general sample measurement, the general sample measurement is continued as it is. Before the general sample measurement, the general sample analysis is started after the result of the quality control sample measurement is confirmed by the user and an instruction to start the general sample measurement is issued (3.
6).

On the other hand, when there is a measurement channel or an analysis module that does not satisfy the predetermined value, a measure corresponding to a combination stored in advance when the measurement channel does not satisfy the predetermined value of the quality control, for example, measurement, The quality control sample measurement of item A is performed on channels 13-1 and 13-2, and when the individual measurement channels satisfy the predetermined value but the combined result of the two channels does not satisfy the predetermined value, the "Maintenance 1" A message indicating that the processing is to be performed is printed out from the printer or displayed on the CRT screen (37). It is determined whether it is before the measurement of the general sample (35), and if it is before the measurement of the general sample, the measurement result of the quality control sample is confirmed by the user, and the general sample measurement is started after the instruction to start the general sample measurement is issued. (3
6). If the quality control sample is being measured during the measurement of the general sample, the measurement of the general sample is continued as it is. If there is an external instruction, the instruction is executed as needed (38).

If an external instruction instructs that the measurement of the general sample for item A in the measurement channel that does not satisfy the predetermined value or the measurement of the general sample itself in the measurement channel be stopped, the measurement is performed. When the stop instruction is issued, the sampling of the general sample for measuring the item A in the measurement channel or the sampling of the general sample itself is stopped, but the measurement is performed on the sample that has already been sampled. The general sample scheduled to be measured in the measurement channel for which the stop instruction has been issued is allocated to another measurement channel. After the measurement of the quality control sample that no longer satisfies the predetermined value, the output of the general sample measurement result in the measurement channel is output together with the result of the measurement in the measurement channel that does not satisfy the predetermined value of the quality control.

Even when the measurement of the item A of the quality control samples a and b is designated only in the analysis module 15-1, the presence of the reagents, disposable chips and reaction vessels installed on the reagent disks in both analysis modules is determined. Confirmation before measurement is performed automatically. As a result, it is confirmed that the preparation for the measurement of the item A is completed in both the analysis modules, but if the quality control information of the designated measurement channel 13-1 does not satisfy the predetermined value, the quality control samples a and b Is automatically transferred from the retest standby unit 21 to the transport path 1
Then, the sample is transported to the analysis module 13-2 through 9 and measurement of each quality control sample is performed in the measurement channel 13-2. If this result satisfies a predetermined value, general sample analysis is performed in 13-2 instead of the measurement channel 13-1.

FIGS. 5 and 6 show display examples of a data list of intraday accuracy management information in the embodiment of FIG. The measurement data of the quality control samples a and b are shown in the display example of the data list of the quality control information of the automatic analyzer as a whole obtained by combining the data of the two measurement channels.
Display example of the data list of each quality control information in 3-2 is shown in two types of tables in FIG. The table displays the measurement items, the type and lot of the quality control sample, the control average value, the control SD, the number of measured data, the average value, the standard deviation, and the like. It is assumed that item A of the quality control sample a is measured five times in each measurement channel in one day. The standard of quality control is the average value 2 x management SD,
Assuming that SD2 × management SD, the measurement data for each measurement channel is within the accuracy control (FIG. 6), but the SD is out of the accuracy control for the entire automatic analyzer (FIG. 5). Values exceeding a predetermined value are displayed in different colors from the surroundings. Thus 2
By displaying the quality control information as a module in which the measurement data of one measurement channel is combined, it is possible to confirm an example that is out of the quality control.

In the daily difference accuracy management, the average value and its variation for each day are monitored. At the end of the measurement for one day, the measurement data obtained for each measurement channel and from the two measurement channels for item A for the item A is collected. The same accuracy management information is obtained, and the same processing as the intra-day accuracy management is performed. However, if the cause is found out of the measured individual data that is out of the specified value and it is necessary to display the result excluding the data, if the data to be deleted is specified, the data will be excluded from the measurement channel The quality control information as a whole obtained by combining the measurement data from the other and each measurement channel is recalculated, and the result is output. In this case, as the day difference data, it is possible to select whether to accumulate data excluding this data or to accumulate all data.

The quality control performed in the embodiment shown in FIG.
Although only the above procedure is performed for the measurement channel 13-1
And 13-2 for each item measured. The same quality control is performed when the same item is measured by a plurality of measurement channels included in one analysis unit or analysis module. When the analysis module has a plurality of measurement channels, the quality control of the automatic analyzer as a whole which combines the measurement data obtained by the plurality of measurement channels for measuring the same item, and the plurality of Accuracy management for each analysis module that combines data obtained from the measurement channels and accuracy management for each measurement channel are performed in accordance with the above processing. For example, FIGS.
In addition to the two types of tables of quality control information for a plurality of measurement channels that measure the same item and quality control information for each measurement channel, a data list of quality control information for each analysis module is output.

As the accuracy control information, in the embodiment of FIG. 1, the average value, the standard deviation and the measurement data for each measurement channel and as a whole are output to a table and an x control chart or an xR control chart. , And outputs information relating to differences between analysis modules or between measurement channels, for example, obtained as numerical values of quality control information such as an average value, a standard deviation, and a variation coefficient, for example, a result of testing the differences. Also, instead of taking the measured number or date on the horizontal axis of the xR control chart, each analysis module or each measurement channel is shown, and a diagram showing the variation in data between analysis modules or between measurement channels is output. Or,
For each of the two quality control samples, a value obtained by each analysis module or each measurement channel is output in a single figure by a binary method.

As the display of the alarm relating to the quality control, as shown in a display example shown in FIG. 7, an output is provided so as to list which measurement channel or module does not satisfy the predetermined value of the quality control for each item. . When there is a set of measurement channels or measurement channels that do not satisfy the predetermined value of the quality control, a message or the like is always output on any screen on the CRT. Alternatively, if the user specifies to display an alarm on the screen, the quality control information of the alarmed item is displayed in a list.
