[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] The test items of the sample analyzer include single-reagent items and multi-reagent items. For single-reagent items, the processor controls the reagent adding component to perform only one reagent filling action; while for multi-reagent items, the processor needs to control the reagent adding component to perform multiple reagent filling actions. In the process of each test item being tested sequentially in the sample analyzer, if there are multi-reagent test items among the multiple test items, the processor may need to control the reagent adding component to add reagents to the reaction cups of two different test items at the same time, causing a conflict in the processor logic.

[0032] In order to solve the above problems, an embodiment of the present application provides a sample analyzer, which uses a processor to determine in advance the newly added test items that will conflict with the test items being executed in the sample analyzer, and avoids the movement conflict of the reagent adding components in the sample analyzer by pausing and / or delaying the sample filling action of the newly added test items.

[0033] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0034] See also Figure 1 , Figure 4 , Figure 1 A schematic diagram of a plan layout of a sample analyzer provided in an embodiment of the present application, Figure 4 A structural block diagram of a sample analyzer provided in an embodiment of the present application.

[0035] The sample analyzer 100 includes a sample adding component 11 , a reagent adding component 12 , a reaction cup grabbing and moving component 13 , an incubation component 14 , a testing component 15 , a mixing component 16 and a cup throwing component 17 .

[0036] The sample loading component 11 includes a sample needle 111 and a driving mechanism 112 thereof. The sample needle 111 can realize rotational motion when driven by the driving mechanism 112, so that the sample needle 111 can absorb sample liquid from the injection area 21 and discharge the sample liquid into the reaction cup of the sample loading area 22, and after discharging the sample liquid, the sample needle 111 is moved to the first cleaning tank 23 for sample loading needle cleaning, and after cleaning, it returns to the position of the injection area 21 to absorb sample liquid again, waiting for the next sample loading action.

[0037] The reagent adding assembly 12 includes a reagent needle 121 and a driving mechanism 122 thereof. The reagent needle 121 can realize rotational motion under the drive of the driving mechanism 122, so that the reagent needle 121 can absorb the reagent 241 from the reagent disk 24 and discharge the reagent 241 into the reaction cup located in the reagent loading area 25; in some embodiments, after discharging the reagent, the reagent needle 121 is moved to the second cleaning tank 26 for reagent needle cleaning, and after the cleaning is completed, it returns to the position of absorbing the reagent again, waiting for the next reagent filling action;

[0038] The cuvette grabbing and moving assembly 13 includes a cuvette gripper 131 and a driving mechanism 132 thereof. The cuvette gripper 131 can realize rotational motion under the drive of the driving mechanism 132, so that the cuvette gripper 131 can move the cuvette in the sample loading area 22 to the incubation position 27; and, after the incubation is completed, the cuvette is moved to the reagent loading area 25; and, after the mixing assembly 16 completes the mixing operation, the cuvette is moved to the incubation position 27 or the test position 28 according to the test item type: if it is a single-reagent test item, the cuvette is moved to the test position 28 to perform the measurement operation; if it is a multi-reagent test item, the cuvette is moved to the incubation position 27, and the incubation and reagent filling actions are performed again until all the reagents are filled, and the cuvette is moved to the test position 28 to perform the measurement operation; and, after the measurement is completed, the cuvette is moved to the cup throwing position 29. Among them, the cuvette gripper can be one or more, so as to ensure that the calling of the cuvette gripper will not conflict when multiple test items are tested.

[0039] The incubation component 14 is used to incubate a reaction cup loaded with a sample or a mixture of a sample and a reagent, so that the reaction solution prepared in the reaction cup reaches a preset temperature, thereby ensuring that the test item can be tested under the preset temperature condition and improving the accuracy of the test result.

[0040] The test component 15 is used to measure a reaction cup loaded with a mixed solution of a sample and a reagent.

[0041] The mixing component 16 is used to mix the mixed solution of the sample and the reagent in the reaction cup located in the reagent loading area 25 by moving up and down, left and right or rotating.

[0042] The cup throwing assembly 17 is used to throw the reaction cup that has been measured and is located at the cup throwing position 29.

[0043] In addition, the sample analyzer further includes a loading module 18 , which is used to continuously supply empty reaction cups to the sample loading area 22 .

[0044] In specific implementation, a single process cycle action of a single reagent test project includes the following actions:

[0045] S11, the loading module 18 prepares the reaction cup;

[0046] S12, the sample needle 111 draws the sample from the sample to be tested in the sample injection area 21, and adds the sample to the reaction cup in the sample loading area 22;

[0047] S13, the cuvette gripper 131 grabs the cuvette to the incubation position 27;

[0048] S14, sample incubation;

[0049] S15, the cuvette gripper 131 grabs the cuvette to the reagent loading area 25;

[0050] S16, the reagent needle 121 draws the reagent 241 from the reagent disk 24 and adds the first reagent R1 into the reaction cup in the reagent loading area 25;

[0051] S17, sample and reagent 241 are mixed;

[0052] S18, the cuvette gripper 131 grabs the cuvette to the testing position 28;

[0053] S19, sample reagent reaction test;

[0054] S110 , the cuvette gripper 131 grabs the cuvette and places it at the cuvette throwing position 29 .

[0055] See also Figure 2 , Figure 2 This is an example diagram of a test task flow for a single reagent test item provided in an embodiment of the present application. Figure 2 As shown, the test task flow of a single test item includes multiple action links and the time period corresponding to each action link. A single single reagent test item includes five action links: adding sample, incubation, adding the first reagent (shown as adding R1), testing, and throwing the cup.

[0056] In some embodiments, the sample adding step performs the sample adding action, the reagent adding step performs the reagent adding action, the duration of the reagent adding step is set to be a unit time period, and the duration of the sample adding, incubation, testing, and cup throwing steps includes at least one unit time period. When the sample analyzer performs a single test item, in the absence of unexpected conflicts, each action link in the single test item is performed in a coherent and sequential manner. According to the execution order of each action link and the execution duration of each action link (equivalent to the number of unit time periods occupied), the start time, end time and / or process time of each action link in the single test item can be pre-set; similarly, when the sample analyzer continuously executes multiple test items, in the absence of unexpected conflicts, not only each action link in the single test item is performed in a coherent and sequential manner, but also the connection between the action links of each test item is performed in a coherent and sequential manner. At this time, according to the execution order of each test item, the execution order of each action link in each test item and the execution duration, the start time, end time and / or process time of each action link in each test item can be pre-set. In this article, the start time, end time or process time of each action link is characterized by the method of "time period + serial number".

[0057] For example, Figure 2 As shown, taking the sample analyzer only executing the test task of the single reagent test item as an example, the starting time of the sample adding link is time period 1, and the ending time is time period 1, and the execution time is 1 unit time period; the starting time of the following incubation link is time period 2, and the ending time is time period 8, and the execution time is 7 unit time periods; the starting time of the following reagent adding link is time period 9, and the ending time is time period 9, and the execution time is 1 unit time period; then, the starting time of the test link is time period 10, and the ending time is time period 16, and the execution time is 7 unit time periods; the starting time of the last cup throwing link is time period 17, and the ending time is time period 17, and the execution time is 1 unit time period.

[0058] The single process cycle actions of the dual reagent test project include the following actions:

[0059] S21, the loading module 18 prepares the reaction cup;

[0060] S22, the sample needle 111 draws the sample from the sample to be detected in the sample injection area 21, and adds the sample to the reaction cup in the sample loading area 22;

[0061] S23, the cuvette gripper 131 grabs the cuvette to the incubation position 27;

[0062] S24, samples were incubated for the first time;

[0063] S25, the cuvette gripper 131 grabs the cuvette to the reagent loading area 25;

[0064] S26, the reagent needle 121 draws the first reagent from the reagent disk 24 and adds the first reagent R1 into the reaction cup in the reagent loading area 25;

[0065] S27, the sample and the first reagent are mixed;

[0066] S28, the cuvette gripper 131 grabs the cuvette to the incubation position 27;

[0067] S29, samples were incubated for the second time;

[0068] S210, the cuvette gripper 131 grabs the cuvette to the reagent loading area 25;

[0069] S211, the reagent needle 121 draws the second reagent from the reagent disk 24 and adds the second reagent R2 to the reaction cup in the reagent loading area 25;

[0070] S212, mixing the sample and the second reagent;

[0071] S213, the cuvette gripper 131 grabs the cuvette to the testing position 28;

[0072] S214, sample reagent reaction test;

[0073] S215 , the cuvette gripper 131 grabs the cuvette and places it at the cuvette throwing position 29 .

[0074] See also Figure 3 , Figure 3 This is an example diagram of a test task flow for a dual-reagent test project provided in an embodiment of the present application. Figure 3As shown, a single dual-reagent test project includes 7 action links: sample addition, first incubation, adding the first reagent (adding R1 in the figure), second incubation, adding the second reagent (adding R2 in the figure), testing, and cup throwing. Among them, the sample addition link performs the sample filling action, the first reagent addition and the second reagent addition link perform the reagent filling action, and the duration of the reagent filling action, sample addition action, and cup throwing action are set to be a unit time period, and the duration of the incubation, testing, and cup throwing links includes at least one unit time period, for example, the first incubation link occupies 7 unit time periods, the second incubation link occupies 20 unit time periods, and the testing link occupies 10 unit time periods. Since each action link is performed in sequence during the test of the sample analyzer, the time period for each action link to be executed is allocated according to the execution order of each action link and the execution time, and the time period corresponding to each action link is obtained. For example, when the sample analyzer executes the test task of the dual-reagent test item, if the time period for executing the sample addition link is cycle 1, then the time period for executing the first incubation link is cycle 2 to cycle 8, the time period for executing the first reagent addition link is cycle 9, the time period for executing the second incubation link is cycle 10 to cycle 29, the time period for executing the second reagent addition link is cycle 30, the time period for executing the test link is cycle 31 to cycle 40, and the time period for executing the cup throwing link is cycle 41.

[0075] It should be noted that adding R1, adding R2, and adding R3 are only used to distinguish the addition of reagents in different time sequences, and do not mean that reagents R1, R2, and R3 are the same or different. For single-reagent test items, double-reagent test items, or triple-reagent test items, the reagents added between different test items can be the same or different; for double-reagent test items or triple-reagent test items, the reagents added between the same test items are generally different.

[0076] See also Figure 4 The sample analyzer 100 includes a processor 10, a sample adding component 11, a reagent adding component 12, a reaction cup grabbing and moving component 13, an incubation component 14, a testing component 15, a mixing component 16, and a cup throwing component 17. The processor 10 is electrically connected to the sample adding component 11, the reagent adding component 12, the reaction cup grabbing and moving component 13, the incubation component 14, the testing component 15, the mixing component 16, and the cup throwing component 17. The processor 10 is configured to coordinate the cooperation between various devices to complete the test process of each test item, specifically:

[0077] In the process of performing the test by the sample analyzer, in some embodiments, after the reagent bottle containing the test sample is placed in the sample analyzer, a complete identification code is affixed to the reagent bottle, and the identification code stores the sample information of the sample contained in the reagent bottle. The processor controls the identification module of the sample analyzer to scan the identification code to obtain the sample information corresponding to the reagent bottle; in some embodiments, if the identification code is not affixed to the reagent bottle, or the identification code is damaged and cannot be recognized, the sample information of the sample can be input manually. Among them, the sample information includes but is not limited to the sample name, patient information, and test type. The test type includes single-reagent test items and multi-reagent test items. Multi-reagent test items generally include double-reagent test items and three-reagent test items.

[0078] In some embodiments, the test type (test item) of each test sample is a single reagent test item:

[0079] In some embodiments, among multiple test items, the time interval between the sample addition stage and the first reagent addition stage of each test item is the same, and the time interval between the Nth reagent addition stage and the N+1th reagent addition stage is the same, and N is a positive integer greater than or equal to 1.

[0080] Taking multiple single-reagent test items as an example, the time interval between the sample adding link and the first reagent adding link is the same. During the continuous testing process of the sample analyzer, the processor controls the sample adding component to continuously perform the sample adding action in adjacent unit time periods, and controls the reagent adding component to continuously perform the reagent adding action in adjacent unit time periods. Figure 5 As shown, the sample adding component continuously performs the sample adding action in cycle 1-cycle 7; the reagent adding component continuously performs the reagent adding action in cycle 9-cycle 15. Since for the same single reagent test item, the reagent needle and the sample adding needle only need to be called once, and the number of unit time periods included in the incubation link between the sample adding link and the reagent adding link of each single reagent test item is the same, when multiple test items are executed continuously, the calling of the sample adding needle is continuous, and the calling of the reagent needle is also continuous, such as Figure 5 At this time, there will be no component call conflict between the test items, and there is no need to adjust the time period for executing the test items.

[0081] In some embodiments, among multiple test items, the duration of the first incubation action of each test item is the same; and / or for each multi-reagent test item, the duration of the incubation action between the Nth reagent filling action and the N+1th reagent filling action is the same, where N is a positive integer greater than or equal to 1.

[0082] by Figure 5Taking the multiple single-reagent test items of as an example, the first incubation phase is between the sample addition phase and the first reagent addition phase. Therefore, the duration of the first incubation phase of each test item is the same. Figure 6 Taking multiple double-reagent test items as an example, the duration of the first incubation phase is the same, and the duration of the second incubation phase is the same. Figure 8 Taking the multiple three-reagent test items as an example, the first incubation phase, the second incubation phase, and the third incubation phase are executed for the same duration. Fig.10 Taking the mixed test project as an example, the duration of the first incubation phase is the same, the duration of the second incubation phase is also the same, and if a three-reagent test project is involved, the duration of the third incubation phase is also the same.

[0083] In some embodiments, when the test type (test item) of each test sample is a double-reagent test item, during the continuous testing of the sample analyzer, the processor controls the sample adding component to sequentially and continuously perform the sample adding action of each test item in adjacent unit time periods, and controls the reagent adding component to sequentially and sequentially perform the reagent adding action of each test item in adjacent unit time periods, such as Figure 6 The sample filling action is continuously executed in cycle 1-cycle 9, and the reagent filling action is continuously executed in cycle 9-cycle 25. Since the reagent needle needs to be called twice for the same double-reagent test item, and each test item is entered in sequence, the reagent needle can only satisfy one test item call once. The second reagent filling action of the double-reagent test item being executed will inevitably conflict with the first reagent filling action of the newly added double-reagent test item. See Figure 6 .

[0084] Therefore, before calling the sample adding component to perform the sample filling action on the newly added dual-reagent test item, the processor can determine whether the time period of the test item being executed overlaps with the time period of the newly added test item based on the time period during which the second reagent filling action of the test item being executed is executed, and based on the first time period during which the first reagent filling action of the newly added test item is executed; if overlap occurs, it indicates that adding the newly added test item within the current time period will conflict with the reagent filling action of the test item being executed. For example, Figure 6 When the time cycle is cycle 17, the reagent needle needs to perform the second reagent filling action on test item 1. At the same time, the reagent needle needs to perform the first reagent filling action on the newly added test item 9. The reagent needle cannot perform two reagent filling actions in the same time cycle, and a reagent needle call conflict occurs.

[0085] Therefore, before calling the sample injection component to perform the sample injection action each time, the processor will determine whether the newly added test item conflicts with the test item being executed. The sample injection action of the newly added test item can only be started if there is no conflict. In this way, it can be ensured that there is no conflict in the reagent needle call between the test items being executed. The conflict in the reagent needle call only occurs between the test items being executed and the newly added test items; by adjusting the time period of each action link of the newly added test item, the conflict in the reagent needle call between the newly added test item and the test item being executed can be avoided.

[0086] For multiple dual-reagent test items, the time interval between the sample addition stage and the first reagent addition stage is the same, and the time interval between the first reagent addition stage and the second reagent addition stage is the same. When multiple test tasks are executed continuously, the reagent needle is called continuously. In order to avoid conflicts, the first reagent filling action of the newly added test item can be arranged after the reagent filling action of the test item being executed is completed, such as Figure 7 As shown, the current time period is period 9. For the test items 1-8 being executed, the reagent needle calling period is continuous from period 9 to period 24. Therefore, the first reagent filling action of the newly added test item can be paused and / or delayed to period 25 at the earliest. Then, the time period of the sample filling action is determined to be period 17 based on the time period of the first reagent filling action. Therefore, when the current time period is period 9, the processor can control the sample adding component to pause, issue an alarm after the pause, and wait for the user to process before controlling the sample adding component to execute the sample filling action of test item 9; the processor can also control the sample adding component to pause and delay for 8 unit time periods before executing the sample filling action of test item 9. Among them, the number of unit time periods of pause and / or delay is equal to the time interval between the time period in which the second reagent filling action is executed and the time period in which the first reagent filling action is executed for a single dual-reagent test item. Figure 7 For a single dual-reagent test item in the test, the time interval is 8 unit time periods. As can be seen from the above, during the time period in which the multiple test items are executed after adjustment, the processor controls the sample adding component to continuously perform the sample filling action in some adjacent unit time periods, and the processor controls the reagent adding component to continuously perform the reagent filling action in some adjacent unit time periods; for example, see Figure 7 In cycle 1 to cycle 8, the processor controls the sample adding component to continuously perform the sample adding action, and controls the sample adding component to perform the sample adding action after an interval of 8 unit time periods; in cycle 9 to cycle 25, the processor controls the reagent adding component to continuously perform the reagent adding action.

[0087] In some embodiments, the first incubation stage is between the sample addition stage and the first reagent addition stage, and the N+1 incubation stage is between the Nth reagent addition stage and the N+1th reagent addition stage. Therefore, the first incubation action of each dual-reagent test item is executed for the same duration; and the second incubation stage is between the first reagent addition stage and the second reagent addition stage. Therefore, the second incubation stage of each dual-reagent test item is executed for the same duration.

[0088] In some embodiments, when the test type (test item) of each test sample is a three-reagent test item, during the continuous testing of the sample analyzer, the processor controls the sample adding component to continuously perform the sample filling action in adjacent unit time periods, and controls the reagent adding component to continuously perform the reagent filling action in adjacent unit time periods. Since the reagent needle needs to be called three times for the same three-reagent test item, and the test items are entered in sequence, the reagent needle can only satisfy one test item call once, the second reagent filling action of the three-reagent test item being executed will inevitably conflict with the first reagent filling action of the newly added three-reagent test item, and the third reagent filling action of the three-reagent test item being executed will inevitably conflict with the second and first reagent filling actions of the newly added three-reagent test item, see Figure 8 .

[0089] Therefore, before calling the sample adding component to perform the sample adding action, the processor can determine whether the time period of the test item being executed overlaps with the time period of the newly added test item based on the time period during which the second and third reagent adding actions of the test item being executed are executed, and based on the time period during which the first and second reagent adding actions of the newly added test item are executed; if overlap occurs, it indicates that adding the newly added test item within the current time period will conflict with the reagent adding action of the test item being executed, see Figure 8 When the time cycle is cycle 21, the reagent needle needs to perform the third reagent filling action on test item 1, and the reagent needle needs to perform the second reagent filling action on test item 5. The reagent needle cannot perform two reagent filling actions in the same time cycle, and a reagent needle call conflict occurs.

[0090] In some embodiments, between multiple three-reagent test items, the time interval between the sample addition link and the first reagent addition link is the same, the time interval between the first reagent addition link and the second reagent addition link is the same, and the time interval between the second reagent addition link and the third reagent addition link is the same. When multiple test tasks are executed continuously, the reagent needle is called continuously. In order to avoid conflicts, the first reagent filling action of the newly added test item can only be arranged after the reagent filling action of the test item being executed is completed. Fig. 9 As shown, the current time period is period 5. For the test items 1-4 being executed, the calling period of the reagent needle is distributed between period 9 and period 24. Therefore, the first reagent filling action of the newly added test item can only be paused and / or delayed to period 25 at the earliest, and then the time period of the sample filling action is determined to be period 17 according to the time period of the first reagent filling action. Therefore, when the current time period is period 5, the processor can control the sample adding component to pause, issue an alarm after the pause, and wait for the user to process before controlling the sample adding component to perform the sample filling action of test item 5; the processor can also control the sample adding component to pause, and delay 12 unit time periods before performing the sample filling action of test item 5. Among them, the number of delayed unit time periods can be greater than or equal to the time interval between the time period when the third reagent filling action of a single three-reagent test item is executed and the time period when the first reagent filling action is executed. For a single three-reagent test item, the time interval is 12 unit time periods. As can be seen from the above, the processor controls the sample adding component to continuously perform the sample adding action in some adjacent unit time periods, and the processor controls the reagent adding component to continuously perform the reagent adding action in some adjacent unit time periods; for example, see Fig. 9 In cycle 1 to cycle 4, the processor controls the sample adding component to continuously perform the sample adding action, and controls the sample adding component to continuously perform the sample adding action after an interval of 12 unit time cycles; in cycle 9 to cycle 12, in cycle 17 to cycle 29, and in cycle 33 to cycle 36, the processor controls the reagent adding component to continuously perform the reagent adding action. It can be seen that the sample adding action of the sample adding component and the reagent adding action of the reagent adding component after adjustment are not completely continuous.

[0091] In some embodiments, the first incubation stage is between the sample addition stage and the first reagent addition stage, and therefore, the first incubation action of each three-reagent test item is executed for the same duration; and, the second incubation stage is between the first and second reagent addition stages, and therefore, the second incubation action of each three-reagent test item is executed for the same duration; and, the third incubation stage is between the second reagent addition stage and the third reagent addition stage, and therefore, the third incubation action of each three-reagent test item is executed for the same duration.

[0092] In some embodiments, when the test type (test item) of the test sample includes at least two of a single reagent test item, a double reagent test item or a three reagent test item, during the continuous testing of the sample analyzer, the processor controls the sample adding component to sequentially and continuously perform the sample filling action within two adjacent unit time periods, and controls the reagent adding component to sequentially and continuously perform the reagent filling action within two adjacent unit time periods. Since there may be a single reagent test item, a double reagent test item or a three reagent test item, there is a same test item, and the reagent needle needs to be called at least once, twice or three times, and the test items are entered sequentially and continuously, and the reagent needle can only satisfy one test item call once, the second reagent filling action of the test item being executed will inevitably conflict with the first reagent filling action of the newly added test item, and / or, the third reagent filling action of the test item being executed will inevitably conflict with the first reagent filling action and the second reagent filling action of the newly added test item.

[0093] In order to avoid conflicts, before calling the sample adding component to perform the sample filling action on the newly added test item, the processor determines whether the time period of the test item being executed overlaps with the time period of the newly added test item based on the time period of the non-first reagent filling action of the test item being executed and the time period of the reagent filling action of the newly added test item; if overlap occurs, it indicates that adding the newly added test item within the current time period will conflict with the reagent filling action of the test item being executed. Therefore, it is necessary to control the sample adding component to pause and / or delay the sample filling action for the newly added test item until the time period of the delayed reagent filling action for the newly added test item does not overlap with the time period of the non-first reagent filling action of the test item being executed.

[0094] The above embodiment specifically includes the following situations:

[0095] In some embodiments, when the test type (test items) of the test sample includes a single-reagent test item and a dual-reagent test item, the processor controls the sample adding component to sequentially and continuously perform sample filling actions during the continuous testing of the sample analyzer within two adjacent unit time periods, and controls the reagent adding component to sequentially and continuously perform reagent filling actions within two adjacent unit time periods. Due to the existence of dual-reagent test items, the same test item and reagent needle need to be called twice, and the test items are entered continuously in sequence. The reagent needle can only satisfy one test item call once. The second reagent filling action of the dual-reagent test item being executed will inevitably conflict with the first reagent filling action of the newly added single-reagent test item or dual-reagent test item. See Fig.10 .

[0096] Therefore, before calling the sample adding component to perform the sample adding action on the newly added test item, the processor determines whether the time period of the test item being executed overlaps with the time period of the newly added test item according to the time period during which the second reagent adding action of the test item being executed is executed and the time period during which the first reagent adding action of the newly added test item is executed; if overlap occurs, it indicates that adding the newly added test item within the current time period will conflict with the reagent adding action of the test item being executed; for example, see Fig.10 When the time cycle is cycle 31, the reagent needle needs to perform the second reagent filling action on test item 2. At the same time, the reagent needle needs to perform the first reagent filling action on test item 23. The reagent needle cannot perform two reagent filling actions at the same time, and the reagent needle calls conflict.

[0097] Furthermore, in some embodiments, the sample addition link between test items and the first incubation link between the first reagent addition link can be set to be executed for the same duration, and the second incubation link between the first reagent addition link and the second reagent addition link can be executed for the same duration; therefore, when multiple test tasks are executed continuously, the time period during which the reagent needle is used to execute the first reagent filling action is continuous, but the time period during which the reagent needle is used to execute the second reagent filling action may not be continuous. In order to avoid conflicts and to reduce waiting time, the first reagent filling action of the newly added test item is scheduled after the second reagent filling action of the test item being executed that conflicts with it is completed, such as Fig.11 As shown, the current time period is period 23. For the test items 2, 6, 7-22 being executed, the calling period of the reagent needle is continuous between periods 13-31, and is dispersed after period 31. Therefore, the first reagent filling action of the newly added test item is suspended and / or delayed to period 32 at the earliest, and then the time period of the sample filling action is determined to be period 24 according to the time period of the first reagent filling action. Therefore, when the current time period is period 23, the processor can control the sample adding component to pause, issue an alarm after the pause, and wait for the user to process before controlling the sample adding component to perform the sample filling action of test item 23; the processor can also control the sample adding component to pause, and perform the sample filling action of test item 23 after at least one unit time period is delayed. Therefore, for the time periods of multiple test items after adjustment, the processor controls the sample adding component to continuously perform the sample filling action in some adjacent unit time periods, and the processor controls the reagent adding component to continuously perform the reagent filling action in some adjacent unit time periods.

[0098] Further, in some embodiments, if there are other reagent filling actions that are continuous with the non-first reagent filling action of the test item being executed that is in conflict after the conflicting time period, the first reagent filling action of the newly added test item is arranged after the execution of the aforementioned other reagent filling actions. The number of unit time periods of suspension and / or delay can be the continuous number of other reagent filling actions that are continuous with the non-first reagent filling action that is in conflict (the continuous number includes the non-first reagent filling action that is in conflict itself, therefore, the number of unit time periods of suspension and / or delay is at least 1 unit time period).

[0099] In some embodiments, when the test type (test items) of the test sample includes a single-reagent test item, a double-reagent test item, and a triple-reagent test item, during the continuous testing of the sample analyzer, the processor controls the sample adding component to sequentially and continuously perform the sample filling action within two adjacent unit time periods, and controls the reagent adding component to sequentially and continuously perform the reagent filling action within two adjacent unit time periods. Due to the existence of double-reagent test items or triple-reagent test items, there is a same test item and reagent needle that needs to be called more than twice, and the test items are entered in sequence continuously, and the reagent needle can only satisfy one test item call once. The second reagent filling action of the double-reagent test item or triple-reagent test item being executed will inevitably conflict with the first reagent filling action of the newly added single-reagent test item, double-reagent test item, or triple-reagent test item. The third reagent filling action of the triple-reagent test item being executed will inevitably conflict with the first reagent filling action or the second reagent filling action of the newly added single-reagent test item, double-reagent test item, or triple-reagent test item. See Fig.12 .

[0100] Before calling the sample adding component to perform the sample adding action for the newly added test item, the processor determines whether the time period of the test item being executed overlaps with the time period of the newly added test item according to the time period of the second and third reagent adding actions of the test item being executed and the time period of the reagent adding action of the newly added test item; if overlap occurs, it indicates that adding the newly added test item within the current time period will conflict with the reagent adding action of the test item being executed. For example, see Fig.12 When the time period is cycle 23, the reagent needle needs to perform the third reagent filling action for test item 3. At the same time, the reagent needle needs to perform the second reagent filling action for test item 7. The reagent needle cannot perform two reagent filling actions at the same time, and the reagent needle call conflicts. In order to avoid conflicts, the sample filling action of the newly added test item 7 is paused and / or delayed. Fig.13Since there is no other continuous reagent filling action after the third reagent filling action of the conflicting test item 3, the number of unit time periods of suspension and / or at least delay is 1. Therefore, for the time periods of the multiple test items after adjustment, the processor controls the sample adding component to continuously perform the sample filling action in part of the adjacent unit time periods, and the processor controls the reagent adding component to continuously perform the reagent filling action in part of the adjacent unit time periods.

[0101] In some embodiments, during the process of continuous testing by the sample analyzer, the processor recognizes that the test types of the multiple test samples include double-reagent test items and triple-reagent test items, and the processor controls the sample adding component to sequentially and continuously perform sample filling actions within two adjacent unit time periods, and controls the reagent adding component to sequentially and continuously perform reagent filling actions within two adjacent unit time periods. Due to the existence of double-reagent test items and triple-reagent test items, the second reagent filling action of the double-reagent test item or triple-reagent test item being executed will inevitably conflict with the first reagent filling action of the newly added double-reagent test item or triple-reagent test item, and the third reagent filling action of the triple-reagent test item being executed will inevitably conflict with the first reagent filling action or the second reagent filling action of the newly added double-reagent test item or triple-reagent test item, see Fig.14 .

[0102] Before calling the sample adding component to perform the sample adding action for the newly added test item, the processor determines whether the time period of the test item being executed overlaps with the time period of the newly added test item based on the time period of the second and third reagent adding actions of the test item being executed and the time period of the reagent adding action of the newly added test item; if overlap occurs, it indicates that adding the newly added test item within the current time period will conflict with the reagent adding action of the test item being executed. For example, see Fig.14 When the time period is cycle 22, the reagent needle needs to perform the third reagent filling action for test item 2. At the same time, the reagent needle needs to perform the second reagent filling action for test 6. The reagent needle cannot perform two reagent filling actions at the same time, and the reagent needle call conflicts. In order to avoid conflicts, the sample filling action of the newly added test item 6 is paused and / or delayed. See Fig.15 Since there is no other continuous non-first reagent filling action after the third reagent filling action of the conflicting test item 2, the number of unit time periods of pause and / or delay is 1. Therefore, for the time periods of the multiple test items after adjustment, the processor controls the sample adding component to continuously perform the sample filling action in some adjacent unit time periods, and the processor controls the reagent adding component to continuously perform the reagent filling action in some adjacent unit time periods.

[0103] It can be seen that in the above embodiments, when there is at least one multi-reagent test item among multiple test items, the processor first determines whether the reagent filling action of the newly added test item will conflict with the non-first reagent filling action of the test item being executed in the sample analyzer before controlling the sample adding component to perform the sample filling action on the newly added test item. If it is detected that there is no conflict, the sample adding component is controlled to perform the sample filling action on the newly added test item; if it is detected that there is a conflict, the sample adding component is controlled to pause and / or delay the sample filling action on the newly added test item, so that the reagent filling action of the newly added test item is staggered with the reagent filling action of the test item being executed. By reasonably arranging the timing of reagent filling, the waiting time of the samples to be processed can be reduced and the overall testing efficiency can be improved.

[0104] In some embodiments, the plurality of test items include single-reagent test items and multi-reagent test items, wherein the single-reagent test items and the multi-reagent test items are executed for different durations.

[0105] Among them, the execution time of a single-reagent test item is different from the execution time of a multi-reagent test item, and the execution time of the test action of each test item can be the same or different. For example, in a coagulation test item, due to the differences in samples, the execution time of the test link is not fixed. Therefore, in fact, the execution time of each test item in multiple test items can be different.

[0106] It should be noted that in the actual test process, the reaction cups of the test items in the incubation phase and the test phase are temporarily retained in the sample analyzer, and the corresponding operation positions are the incubation position and the test position, respectively. The number of incubation positions and the test positions is limited. And due to the existence of multi-reagent test items, the test time period of multiple test items needs to be adjusted according to the real-time operation status of the test items. The test time of each test item may also be different, which makes the test time of multiple test items uncertain, and it is easy to cause the problem of insufficient test positions, resulting in the blockage of the test process of the test items being executed. In particular, after the test item executes the last reagent filling action, if the test action is not completed within the preset time, the sample and the reagent react, which may cause deviations in the test results.

[0107] Therefore, different methods can be used according to the settings of the incubation position and the test position to prevent the test items from being blocked in the sample analyzer during the test process.

[0108] In some embodiments, the incubation position and the test position are set at the same operation position. That is, the reaction cup of the incubation stage or the test stage can be placed in the incubation position or the test position. Therefore, the processor can determine whether there is an unoccupied incubation / test position in the sample analyzer before controlling the sample adding component to perform the sample filling action. Specifically, the processor determines the total number of test items that perform incubation actions and test actions in the test items being executed in the current time period before controlling the sample adding component to perform the sample filling action. If the total number exceeds the number of incubation / test positions of the sample analyzer, there is no unoccupied incubation / test position in the sample analyzer; if the total number is less than the number of incubation / test positions of the sample analyzer, there is an unoccupied incubation / test position in the sample analyzer. In some embodiments, if there is an unoccupied incubation / test position, the processor controls the sample adding component to perform the sample filling action on the newly added test item. In some embodiments, if there is no unoccupied incubation / test position, the processor controls the sample loading component to pause and / or delay the sample loading action for the newly added test item until at least one unoccupied incubation / test position appears in the sample analyzer, and then controls the sample loading component to perform the sample loading action for the newly added test item. This avoids the problem of insufficient test positions due to uncertainty in test time, which in turn causes more samples to wait at the incubation position for the subsequent last reagent loading action and test action.

[0109] In some embodiments, the incubation position and the test position are set at different operating positions. Among them, when the incubation position and the test position are set at different operating positions, that is, the incubation action can only be performed in the incubation position, and the test action can only be performed in the test position. In order to avoid too many test items waiting for a long time to execute the test action after the last reagent filling action is executed, in some embodiments, when the processor controls the reagent adding component to execute the last reagent filling action of the test item, it is necessary to judge in advance the situation that the number of test positions is insufficient. When it is detected that all the test positions are in an occupied state, the reagent adding component is controlled to pause and / or delay the execution of the last reagent filling action of the corresponding test item until there is at least one test position in an unoccupied state, and then the reagent adding component is controlled to execute the last reagent filling action of the corresponding test item.

[0110] In some embodiments, the processor can also set a preset test duration, and each test item is set with a test duration of the test link. When the processor controls the reagent adding component to perform the first reagent filling action on the test item, the test timing starts. When it is detected that the actual test duration of the test item being executed exceeds the preset test duration, the corresponding test item is determined to be an abnormal test item, and the cup throwing action is directly performed to end the test process of the abnormal test item in advance. In some embodiments, the complete second test process can be re-executed on the sample of the abnormal test item, including five action links of adding samples, incubation, adding reagents, testing, and cup throwing. At the same time, the test duration of the test link of the second test process is reset. The reset second test duration must be greater than the preset maximum test duration, so that the second test duration is not limited by the preset test duration. After the test duration reaches the reset second test duration, the cup throwing component is controlled to perform the cup throwing action to end the test process.
