Description

Sample loading area expansion method and device and sample analyzer

Technical Field

The present disclosure relates to medical devices, and more particularly, to a method and apparatus for expanding a sample loading area, and a sample analyzer.

Background

In fully automated sample analyzers, common test types include routine sample testing, calibration testing, and quality control testing. Conventional sample testing is the analytical testing of patient samples. Calibration tests are a prerequisite for analyzers that perform patient sample testing, and typically all analytical items need to be calibrated with one or more concentration calibrators. Quality control testing is one of the guarantees that the test results are reliable when the analyzer performs the test on the patient sample. Therefore, the instrument is typically required to perform routine sample testing and quality control testing on a daily basis, with calibration testing being performed on a regular or irregular basis as required. Analyzers typically support the simultaneous testing of multiple items, and the control and calibrator of each item are typically separated into multiple concentration levels, and since the testing of the calibrator and control is relatively fixed, users typically wish to place the calibrator and control in position and then make frequent changes.

According to different sample introduction modes, the full-automatic sample analyzer is divided into rail type sample introduction and disc type sample introduction. In a common instrument with a rail sampling structure, different types of sample racks are usually provided for a user, and at least comprise a conventional sample rack, a calibration sample rack and a quality control sample rack, the instrument automatically identifies the type of the sample rack and the number of the sample rack, and the user only needs to set information of a calibration product and the quality control product on the corresponding sample rack. However, in this solution, the cost of the instrument is high, the structure is complex, a device capable of identifying the type and the number of the sample rack needs to be designed, and because the sample racks are distinguished, samples of different test types cannot share the sample rack, a user needs to be equipped with a large number of sample racks, the utilization rate of the sample racks is relatively low, and the use cost is increased. Therefore, this solution is often used in high-end and medium-end analytical instruments with large sample volumes and is not suitable for laboratories with small sample volumes.

In small and medium-sized analytical instruments, a sample disc structure is mostly adopted, special positions can be reserved as a calibration product position and a quality control product position, and even a special disc is used as a calibration and quality control disc. However, the dedicated calibrator and quality control positions result in relatively low utilization rate, which results in waste of space and cost.

However, the sample injection structure of the analyzer needs to occupy a large space no matter in a rail type or a disc type. Aiming at some use occasions, a user provides a miniaturized analysis instrument, the analysis instrument is required to occupy smaller space on the whole, and more constraint conditions are provided for the design of the structure on the premise of keeping various functions of the full-automatic sample analyzer.

Detailed Description

In the embodiments of the present application, in order to better explain the present application, the sample analyzer is mainly illustrated by taking an immunoassay analyzer as an example, correspondingly, the sample loading area is taken as an example of a sample loading area on the immunoassay analyzer, and the sample testing type is taken as an example of conventional sample testing, calibration testing and quality control testing. It should be understood that in other embodiments, the sample loading zone expansion method and apparatus may be applied to other instruments, such as biochemical analyzers, molecular diagnostics, etc.; also, the sample loading zone may be a reagent loading zone.

The inventive concept of the present application is first explained below:

taking an immunoassay analyzer as an example, the occupation of a sample position (sample loading area) on the analyzer is divided into physical position occupation and logical position occupation of position setting in a test. The sample locations are limited and unique to the physical location occupancy under test. The logical occupation of the position setting means that positions are set for some tests on the operation software, and the positions occupied by the logic can be expanded infinitely theoretically. The sample position placing area determined on the instrument is defined as a physical position and a physical area, the sample position is expanded and defined as a logical position and a logical area through software, and all the logical areas correspond to the same physical area. Therefore, the contradiction between the occupation requirements of the limited sample position and the occupation requirements of a plurality of sample testing types on the same sample position at different times is solved, and the expansion of the limited sample position is realized.

The present application will be described in further detail below with reference to the accompanying drawings by way of specific embodiments.

The embodiment provides an expansion method and an expansion device of a sample loading area and an immunoassay analyzer.

Referring to fig. 1, a schematic structural diagram of an immunoassay analyzer according to the present embodiment is shown, in which a sample loading area 10, a reagent loading area 20, and an expansion device (not shown in fig. 1) of the sample loading area are disposed on the immunoassay analyzer.

When a user performs a test using the immunoassay analyzer, the immunoassay analyzer automatically performs a test after a sample is loaded from the sample loading area 10 and a reagent is loaded in the reagent loading area 20. For samples in the sample loading zone 10, the corresponding samples need to be replaced for different tests; since most tests use the same reagent for the reagents in the reagent loading zone 20, the reagents are often replaced only after they have been used.

Referring to fig. 2, fig. 1 shows an immunoassay analyzer having a sample loading zone 10 in the form of a channel having 6 channels, each channel having 10 sample sites. In this embodiment, the present application is described by taking only this type of sample loading area as an example, in other embodiments, the number of channels and the number of sample sites in the sample loading area may be different, and even the sample loading area may have other structures such as a disk shape and a matrix shape.

Referring to fig. 3, a schematic block diagram of an expansion device of a sample loading area according to the present embodiment is provided, in which the expansion device of the sample loading area includes a human-computer interaction module 301 and an execution module 302.

The device will be described with reference to the method for expanding the sample loading area provided in this embodiment.

Referring to fig. 4, a schematic flow chart of the method for expanding the sample loading area provided in this embodiment includes the following steps:

step 4.1: and the man-machine interaction module displays a logic area selection interface to a user based on a test request of the user, each logic area comprises a plurality of logic positions, and the logic positions of each logic area correspond to the physical positions of the sample loading area one to one.

Specifically, the interface displayed to the user by the human-computer interaction module can be provided by software. Also, the interface may have a difference term for different sample test types, the same being that the user may be provided with a logical zone selection term. As shown in fig. 5 and 6, the human-computer interaction module presents a logical area selection interface to the user for calibration testing and routine sample testing, respectively. When the man-machine interaction module displays the selection interface of the logic area to the user, determining the sample test type applied by the user according to the test request of the user, and when the sample test type applied by the user is a calibration test, displaying the interface shown in the figure 5 to the user; when the type of sample test requested by the user is a regular sample test, the user is presented with an interface as shown in fig. 6.

Step 4.2: and the execution module determines the logic area participating in the test according to the selection of the user.

As shown in fig. 5 and 6, the user selects the logic area to be tested in a plurality of logic areas through a pull-down option, for example, in fig. 5, the user selects logic area 3 as the logic area to be tested in the calibration test and selects logic area 1 as the logic area to be tested in the regular sample test. Of course, the user also selects the logical location to participate in the test, such as the 10 th location of the 6 th channel selected in FIG. 6, via the pull-down option.

Referring to fig. 5, usually, when a user performs a test, the logic positions corresponding to the selected calibrator 1, calibrator 2, and calibrator 3 are the 1 st, 2 nd, and 3 rd positions of the 1 st channel, respectively, and in a subsequent test, the default logic positions corresponding to the calibrator 1, calibrator 2, and calibrator 3 are the 1 st, 2 nd, and 3 rd positions of the 1 st channel, respectively. To the calibration test and the quality control test that test information is relatively fixed, this kind of be provided with and do benefit to and make the user form the custom in the use, place some fixed samples in some fixed positions to avoid loaded down with trivial details position of setting repeatedly and release position operation, with improvement operating efficiency, reduce the risk of makeing mistakes.

Of course, to accommodate different testing requirements, the user may also modify the logical position definition of the sample via the pull-down option in fig. 5. For example, the calibrator 1 originally placed at the 1 st channel and 1 st position of the 3 rd logic area is modified to be placed at the 1 st channel and 4 th position of the 3 rd logic area.

It should be noted that, in general, to avoid sample placement confusion, one logic area is only used for placing samples of the same test type, for example, logic area 3 is only used for placing calibration test samples, and logic area 1 is only used for placing regular test samples. Of course, in some embodiments, one logic area may be used for placing samples of multiple test types, for example, part of logic locations in logic area 3 may be used for placing calibration test samples, and part of logic locations may be used for placing quality control test samples. As long as the physical position corresponding to the logical position for placing the calibration test sample does not coincide with the physical position corresponding to the logical position for placing the quality control test sample.

Step 4.3: the execution module 302 starts testing for the logic area to be tested in a default or designated manner, including: and acquiring sample information set at each logic position on the logic area to be detected, and taking the physical position of the sample loading area corresponding to the logic position on which the sample is set on the logic area to be detected as the actual placement position of the sample. The sample information includes various information related to the sample, such as a sample test type, a test item, and a logical location corresponding to the sample.

It is assumed that the sample loading area (physical area) of the immunoassay analyzer is mapped to logical area 1, logical area 2, logical area 3, logical area 4, and logical area 5. Of course, the sample loading area may be mapped to more logical areas as desired. In particular, the instrument may be configured with as many logical zones as possible, for example 20, to ensure that the user has enough logical zones to use during the test. Of course, the user may also actively increase the number of logical areas during the test. For example, the user modifies the number of the logical areas through a human-computer interaction interface provided by the human-computer interaction module to meet the use requirement.

When all the positions of the calibrator are set in the logical area 3 and all the positions of the quality control are set in the logical area 4, the

logical areas

1 and 2 are set as the normal sample positions. The setting of the logical position of the calibrator is shown in fig. 5. And selecting the logic areas and the logic positions corresponding to different calibration products by a user through a human-computer interaction module. The arrangement of the logic positions of the regular samples is shown in fig. 6, that is, the regular sample 1 is arranged in the 10 th sample position of the 6 th channel of the logic area 1, and the samples can be used for testing the test items listed in fig. 6, which are well known to those skilled in the art and the description thereof is omitted here.

The logical locations within each logical zone are predefined for placing what samples prior to testing. For routine sample testing, different samples typically refer to blood samples of different patients; for different calibrators and quality controls, different samples generally refer to different concentrations of calibration sample and quality control sample.

When starting the test, usually only the samples on the same logical area can be tested at one time, so as to ensure that different logical division periods occupy the same physical area. When the sample test type applied by the user is a calibration test and the logic area is selected as the logic area 3, the execution module of the instrument acquires sample information set at each logic position on the logic area 3, and takes the physical position of the sample loading area corresponding to the logic position where the sample is set on the logic area 3 as the actual placement position of the sample. After the calibration test is completed, the user can apply for other sample test types, for example, apply for a quality control test, and select to use the logic area 4, after the user has replaced the sample, the quality control test is started, the execution module of the instrument obtains sample information set at each logic position on the logic area 4, and the physical position of the sample loading area corresponding to the logic position where the sample is set on the logic area 4 is used as the actual placement position of the sample.

Referring to fig. 7, a user is shown selecting logic area 1 as the logic area to be tested when starting the conventional sample test. Of course, fig. 7 also shows that when the reagent disk also uses the expansion method provided by the present embodiment, the logical area 1 of the reagent disk is simultaneously selected as the logical area to be tested.

Referring to fig. 8, it shows an interface for setting the logical position of the reagent disk by the user when the reagent disk also uses the expansion method provided by the present embodiment. Likewise, a reagent disk may be mapped to multiple logical zones. Assuming that the test items are classified into a first type and a second type, it may be set that the first type test items use the logical area 1 and the second type test items use the logical area 2. When performing the first type of test items, the user chooses to perform the test using logical area 1. When the second type of test items are needed, the user selects the logic area 2 for testing after replacing the reagent. Thus, multiplexing of physical locations on the reagent tray can be achieved.

The present application is further described below in connection with several different application scenarios.

(1) When only one logic area participating in the test is determined in the step 4.2, the execution module receives a test starting instruction, and starts the test for the only one logic area according to the test starting instruction.

Referring to fig. 5, when all the calibrators are set in the logic area 3, the user places corresponding samples in the sample loading area according to the sample information defined in each logic position in the logic area 3, generates a test start instruction after the instrument detects that the samples are loaded, and starts testing with respect to the logic area 3 after the execution module receives the test start instruction.

After the instrument detects that the sample is loaded, a test starting instruction is generated, and specifically, the test starting instruction is generated after the sensor senses that the sample is placed in the sample loading area.

In other embodiments, the test starting instruction may also be input by the user, as shown in fig. 7, after the user places the sample in the sample loading area, the user clicks the "confirm" option through the interactive interface provided by the human-computer interaction module to generate the test starting instruction. In this manner, each time a test is initiated, the user is actively required to confirm and give instructions to initiate the test.

(2) If a large number of projects are performed and the location of one logic area is not sufficient to set all the calibrators or quality controls, the calibrators or quality controls may be set in a plurality of logic areas, respectively. For example, the calibration object positions are set in the logical area 3 and the logical area 5.

In some embodiments, when there are multiple logic areas participating in the test determined in step 4.2, the human-computer interaction module determines a logic area to be tested among the multiple logic areas participating in the test according to the selection of the user; and when the test for the logic area to be tested is finished, the execution module stops the test, and starts the test for the new logic area to be tested after the fact that the user specifies the new logic area to be tested is detected.

As shown in fig. 9, the human-computer interaction module obtains a test start instruction input by the user, at this time, the user selects the logic area 3 as the logic area to be tested, and the execution module starts testing for the logic area 3. And stopping the test after the test aiming at the logic area 3 to be tested is completed. Specifically, the instrument may display the test start interface shown in fig. 9 through the human-computer interaction module, and the user may designate, through a pull-down menu provided by the human-computer interaction module, the next logic region where the sample test type is located as a new logic region to be tested, confirm that the test is started, and continue to test the newly designated logic region to be tested through the execution module. In this application example, the next logic area to be tested is the logic area 5, and as shown in fig. 10, the operation interface is an operation interface in which after the test is finished in the ground logic area 1 and the test is stopped, the user designates the next logic area to be tested (the logic area 5) to continue the test.

Namely, samples applied in the same batch are distributed in a plurality of logic areas simultaneously, when the test is started, a user firstly designates one logic area to be tested, after the sample suction is completed, the user confirms that the samples are replaced and placed in the unique physical area, and then confirms that the test of the other logic area to be tested is started.

(3) In some embodiments, when there are multiple logic areas participating in the test determined in step 4.2, the human-computer interaction module determines a test sequence of the multiple logic areas participating in the test according to the selection of the user, and sequentially uses the multiple logic areas participating in the test as the logic areas to be tested according to the test sequence; and when the test for the logic area to be tested is finished, the execution module stops the test and starts the test for the next logic area to be tested after receiving the test starting instruction.

The test starting instruction can be generated by a sensor arranged on the sample loading area after the sensor senses that the sample is placed in; or by user input. Here, the description will be given taking an example of starting the test instruction by the user input.

Specifically, the test sequence may be a default test sequence in which tests are performed in a descending order according to the number of the logical area. Or may be an order specified by the user. It should be noted that after each test of a logic area is completed, the test is stopped first, for example, a human-computer interaction module pops up a test start interface as shown in fig. 7, 9 or 10, at this time, the user no longer needs to specify a new logic area to be tested through a pull-down menu, and the instrument automatically tests the next logic area after the user selects an option "confirm" according to the set test sequence.

(4) In some embodiments, when there are a plurality of determined logical areas participating in the test, and the physical locations corresponding to the logical locations participating in the test in each logical area are not repeated, the execution module starts the test of the plurality of logical areas after receiving the start test instruction. Specifically, the plurality of logic areas may be tested together, or each logic area participating in the test may be tested sequentially according to a test default test sequence requested by the user.

As shown in fig. 11, it is assumed that the logical areas participating in the test determined by the user are

logical areas

1, 2, and 3, and the logical positions participating in the test are logical area 1, logical area 2, logical area 1, channel 2, and logical area 3, channel 1, and location 3, respectively. At this time, since the three logical positions correspond to different physical positions, the three logical positions do not conflict with each other, and the logical area 1, the logical area 2, and the logical area 3 can be tested simultaneously. Or selecting to start testing from the logic area 1, and after the testing of the logic area 1 is finished, directly testing each logic area participating in the testing in sequence according to the test default test sequence requested by the user. For example,

logical zones

1, 2, 3 are tested in sequence. At this time, when one logic area is tested, the test instruction is no longer required to be received so as to start the test of the next logic area.

According to the sample loading area expansion method, the sample loading area expansion device and the sample analyzer, on one hand, multiplexing of the same sample position is achieved. Compared with the mode of adopting different types of sample racks to distinguish the sample testing types in the prior art, the internal structure of the instrument can be simplified, and the cost is saved. On the other hand, after the test of one sample type is finished, the position of the logic area does not need to be released, and when the test of other sample types is carried out, only the corresponding logic area needs to be selected, so the operation is simpler and more convenient.

Since the calibration test, the quality control test and the routine test are usually not performed at the same time, the test information of the calibration test and the quality control test is relatively fixed, and for simplicity of operation, it is desirable that the calibration test and the quality control test can be fixedly arranged at some specified positions to avoid repeated arrangement of the positions. Through the design of the logic area, a plurality of calibration products and quality control products can be arranged at designated positions, the positions are completely free from conflict with daily test samples, and tedious repeated position arrangement and position release operations are avoided. Meanwhile, the position information of the quality control product and the calibration product on the instrument is fixed, so that the operation efficiency is improved, and the error risk is reduced. Through the design of the logic area, a unique physical area is shared, the settable number of the sample loading areas of the instrument is expanded on the premise of not increasing the space and the cost of the instrument, and the operation convenience of a user is improved.

When the number of samples is larger than the number of physical positions in the conventional sample test, the scheme of the invention can conveniently support the application of all sample tests at one time and set the logical positions for all samples, so that the samples on the physical positions are replaced after the test of one logical area is finished in the test process, and the subsequent sample test can be continued without carrying out the sample application operation again. Under the condition that the physical position of the sample loading area is limited, the user operation in the large-sample-quantity test is simplified, and the test efficiency is improved.

The sample expanding method and the sample expanding device have better operation convenience particularly when the sample loading area is of a disc structure. When applying for the sample test of a plurality of logic areas at one time, in the process of executing the test of one logic area, a user can prepare the sample to be tested of the next logic area by using a standby sample disc, thus, after the sample test of the current logic area is finished, the sample of the whole disc is directly replaced, the test of the next logic area can be rapidly started, the time consumption caused by taking and placing a plurality of sample positions on the sample disc one by one is avoided, and the test pause time of the instrument due to the sample replacement is shortened to the shortest. When the test sample size is more, this kind of design makes the operation more convenient, and efficiency of software testing is higher.

Those skilled in the art will appreciate that all or part of the steps of the methods in the above embodiments may be controlled by a program to be performed by associated hardware, and the program may be stored in a computer-readable storage medium, and the storage medium may include: read-only memory, random access memory, magnetic or optical disk, and the like.

The foregoing is a more detailed description of the present application in connection with specific embodiments thereof, and it is not intended that the present application be limited to the specific embodiments thereof. It will be apparent to those skilled in the art from this disclosure that many more simple derivations or substitutions can be made without departing from the inventive concepts herein.
