Description

Technical Field

[0001] This application relates to the field of sample analysis, and more particularly to a sample analyzer and a control method for the sample analyzer. Background Technology

[0002] Sample analyzers are used to analyze cellular particles in biological samples, such as classifying and counting cells. Sample analyzers can be blood analyzers or flow cytometers. In practical applications, when the sample volume is small, it is necessary to transfer the sample to a micro-volume container, insert the micro-volume container into the sample tube, and manually change the type of sample tube to avoid alarms caused by mismatched sample tube types in subsequent tests. Currently, related technologies typically require users to manually change the type of each sample container, which is inconvenient, inefficient, and time-consuming when there are many sample containers, further reducing the efficiency of sample testing. Summary of the Invention

[0003] This application provides a sample analyzer and its control method, which solves the problem in related technologies where users manually change the type of each sample container in sequence, resulting in reduced sample testing efficiency.

[0004] In a first aspect, this application provides a sample analyzer, comprising: a pipette including a sample needle for drawing a sample from a sample container and distributing at least a portion of the drawn sample to a reaction cup; a sample rack having multiple placement positions for placing the sample container; a display device for displaying a setting interface for a user to set the container type corresponding to the sample container in the placement position of the sample rack; a detection device for detecting the test liquid containing the sample in the reaction cup to obtain a detection result; and a control device for associating the set container type corresponding to the sample container with the sample rack and the placement position in the sample rack to obtain association information, and controlling the sample needle to draw a sample from the sample container and distributing at least a portion of the drawn sample to the reaction cup according to the association information, and controlling the detection device to detect the test liquid containing the sample in the reaction cup to obtain a detection result.

[0005] Secondly, this application also provides a control method for a sample analyzer, the method comprising:

[0006] The sample analyzer's settings interface displays at least one set of selectable objects, including sample rack number option, placement position start option, placement position end option, and sample container type option;

[0007] In response to parameter setting operations on the at least one set of selectable objects, the parameter values ​​for the sample rack number option, the placement position start option, the placement position end option, and the sample container type option are determined respectively.

[0008] In response to the save operation of the at least one set of selectable objects, the parameter values ​​of the sample rack number option, the placement position start option, the placement position end option, and the sample container type option are associated to obtain association information, and the association information is saved.

[0009] Thirdly, this application also provides a control method for a sample analyzer, the method comprising:

[0010] The target sample rack containing the sample to be collected is identified, resulting in a fourth identification result;

[0011] The image of the sample container corresponding to the placement position in the target sample rack, captured by the imaging device, is used for image recognition to obtain a fifth recognition result;

[0012] Obtain the target sample rack and the association information between the placement position and the container type in the target sample rack. Based on the association information, the fourth identification result and the fifth identification result, determine the target container type corresponding to the sample container in each placement position in the target sample rack.

[0013] According to the target container type corresponding to each sample container, the sample needle is controlled to draw samples from the sample container and distribute at least a portion of the drawn samples to the reaction cup, and the detection device is controlled to detect the test liquid containing the sample in the reaction cup to obtain the detection result.

[0014] The sample analyzer and its control method provided in the above embodiments display a setting interface on a display device for users to set the container type corresponding to the sample container in the placement position of the sample rack. The control device associates the set container type with the sample rack and the placement position, thus achieving the association between the sample rack and the placement position and the container type corresponding to the sample container. This solves the problem in related technologies where users have to manually change the type of each sample container sequentially, which reduces the testing efficiency of the samples. It eliminates the need to manually change the container type of each sample container sequentially, thereby enabling batch testing. The operation is simple and convenient, and can effectively improve the testing efficiency of the samples. Attached Figure Description

[0028] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings. Similar elements in different embodiments are referred to by associated similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of this application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to this application are not shown or described in the specification. This is to avoid obscuring the core parts of this application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0029] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0030] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0031] In practical applications, when the sample volume is small, it is necessary to transfer the sample to a micro-volume container, insert the micro-volume container into the sample tube, and manually change the type of the sample tube to avoid alarms caused by sample tube type mismatch in subsequent tests. Currently, related technologies usually require users to manually change the type of each sample tube, which is inconvenient, inefficient, and when there are many sample containers, manually changing the type of each sample container sequentially takes even more time, thus reducing the efficiency of sample testing.

[0032] Therefore, embodiments of this application provide a sample analyzer, a control method for the sample analyzer, and a computer-readable storage medium. By displaying a setting interface on a display device for users to set the container type corresponding to the sample container in the placement position of the sample rack, and having the control device associate and save the set container type with the sample rack and its placement position, batch setting of sample racks and placement positions with the corresponding container types can be achieved. During testing, the sample container type is determined based on the saved association information. This solves the problem in related technologies where users manually change the type of each sample container sequentially, leading to reduced sample testing efficiency. It eliminates the need for manual changes to the container type of each sample container, enabling batch testing. The operation is simple and convenient, effectively improving sample testing efficiency. The following will describe in detail the working principle of the sample analyzer and how to associate the container type with the sample rack and its placement position.

[0033] This application discloses a sample analyzer in some embodiments. Please refer to... Figure 1 The sample analyzer 1 includes a sample module 10, a reagent module 20, a dispensing mechanism 30, an analysis module 40, a reaction module 60, and a control module 50.

[0034] The sample module 10 is used to carry the sample to be injected. For example, the sample module 10 can be implemented using a sample delivery module (SDM) and a front-end track. In other embodiments, it can also be implemented using... Figure 1 The rotary sample tray shown has at least one sample position for placing a sample container, such as a sample tube. The sample can be moved to the corresponding position by rotating the sample tray, such as the position for the dispensing mechanism 30 to pick up the sample.

[0035] The reagent module 20 is used to hold reagents. In some embodiments, the reagent module 20 can be a reagent tray, which is arranged in a disc shape and has multiple reagent positions for holding reagent containers. The reagent module 20 can rotate and drive the reagent containers it holds to rotate, for rotating the reagent containers to a specific position, such as the position where the dispensing mechanism 30 picks up the reagent. The number of reagent modules 20 can be one or more. The reagent containers held by the reagent module 20 include at least a magnetic bead reagent container, which contains magnetic bead reagent, and the magnetic bead reagent includes diluent and magnetic beads.

[0036] The dispensing mechanism 30 is used to aspirate samples from a sample container and dispense them into a reaction container (or reaction cup), and to aspirate reagents from a reagent container and dispense them into the reaction container. In some embodiments, the dispensing mechanism 30 includes a sample dispensing mechanism 31 and a reagent dispensing mechanism 32, which can operate independently to dispense samples and reagents respectively, thereby improving efficiency. Exemplarily, the sample dispensing mechanism 31 includes a sample needle and a first moving component, which drives the sample needle to aspirate the sample carried by the sample module 10 and to move to the reaction container to be added to, dispensing the sample into the reaction container. The reagent dispensing mechanism 32 includes a reagent needle and a second moving component, which drives the reagent needle to aspirate the reagent carried by the reagent module 20 and to move to the reaction container to be added to, dispensing the reagent into the reaction container. Both the first and second moving components can be two-dimensional or three-dimensional driving mechanisms, which can be designed according to specific needs. In other embodiments, the dispensing mechanism 30 includes a set of mechanisms used for both sample dispensing and reagent dispensing.

[0037] The control module 50 may include a processor and a memory for controlling the operation of the reagent module 20, the dispensing mechanism 30, the analysis module 40, and the reaction module 60.

[0038] The reaction module 60 is used to carry the reaction container and has at least one reaction position for placing the reaction container to incubate the reaction solution in the reaction container. The reaction solution is prepared by combining at least a sample and reagents. In some embodiments, the reaction module 60 can be a rotary reaction disk with multiple reaction positions. Specifically, the reaction disk can rotate and drive the reaction container in its reaction position to rotate, for managing the reaction container and incubating the reaction solution in the reaction container within the reaction disk.

[0039] The analysis module 40 can be a photometric component, which is used to perform photometric measurements on the incubated reaction solution to obtain the sample's reaction data. For example, the photometric component can detect the absorbance or photometric value of the reaction solution to be tested, and calculate the concentration of the analyte in the sample through a calibration curve.

[0040] Please refer to Figure 2 In some embodiments, the sample analyzer 1 may include a pipetting device 31, a sample holder 10, a display device 70, a detection device 40, a control device 50, an input device 80, and an imaging device 90. These will be described in detail below.

[0041] Pipette 31, also known as a sample dispensing mechanism, such as Figure 1 The sample dispensing mechanism 31 includes a sample needle for drawing a sample from a sample container and dispensing at least a portion of the drawn sample into a reaction cup.

[0042] Sample holder 10, also known as sample module, such as Figure 1 The sample module 10 has multiple placement positions for placing sample containers.

[0043] The display device 70 can be used to display information. In some embodiments, the sample analyzer 1 itself can integrate a display module. In other embodiments, the sample analyzer 1 can also be connected to a computer device (e.g., a computer) and display information through the display unit (e.g., a screen) of the computer device. These all fall within the scope defined and protected by the display device 70 herein. In the embodiments of this application, the display device 70 is at least used to display a setting interface for the user to set the container type corresponding to the sample container in the placement position of the sample rack 10.

[0044] It should be noted that there are various types of sample racks 10, such as regular sample racks, emergency sample racks, calibration sample racks, quality control sample racks, maintenance sample racks, manual retest sample racks, etc.

[0045] Users can set the container type corresponding to the sample container in the placement position of the sample rack 10 on the settings interface. For example, the container type corresponding to the sample container can include a constant container and a micro container, wherein the constant container is used to hold constant samples, the micro container is used to hold micro samples, and the micro container can hold fewer samples than the constant container.

[0046] In some embodiments, the container types corresponding to multiple placement positions in the sample rack 10 may be the same or different. For example, the sample rack 10 may hold sample containers of different container types in a mixed manner, such as micro-volume containers and constant-volume containers.

[0047] It should be noted that by setting the container types corresponding to multiple placement positions in the sample rack 10 to be the same or different, sample containers of different capacities can be mixed and placed in the same sample rack 10, so as to simultaneously test samples of different capacities.

[0048] Detection device 40, also known as analysis module, such as Figure 1 The analysis module 40 is used to detect the test liquid containing the sample in the reaction vessel and obtain the test results.

[0049] Control device 50, also known as control module, such as Figure 1 The control module 50 is used to associate the container type corresponding to the set sample container with the sample rack 10 and the placement position in the sample rack 10 to obtain association information, and control the sample needle to draw the sample from the sample container according to the association information and distribute at least part of the drawn sample to the reaction cup, and control the detection device 40 to detect the test liquid containing the sample in the reaction cup to obtain the detection result.

[0050] Input device 80 is used to receive user input. Commonly, input device 80 can be a mouse and keyboard, etc. In some cases, it can also be a touch screen, which provides the function of allowing users to input and display content. Therefore, in this example, input device 80 and display device 70 are integrated together. Of course, in some examples, input device 80 can even be a voice input device with speech recognition capabilities.

[0051] The imaging device 90 may include a camera for capturing images of the sample container.

[0052] It should be noted that, in this embodiment of the application, by displaying a setting interface on the display device 70 for users to set the container type corresponding to the sample container in the placement position of the sample rack 10, and by the control device 50 associating the set container type corresponding to the sample container with the sample rack 10 and the placement position in the sample rack 10, it is possible to batch set the association between the sample rack 10 and the placement position and the container type corresponding to the sample container. This solves the problem in the related technology where the user has to manually change the type of each sample container in turn, which leads to a decrease in the testing efficiency of the samples. It eliminates the need to manually change the container type of each sample container in turn, thereby enabling batch testing. The operation is simple and convenient, and can effectively improve the testing efficiency of the samples.

[0053] In some embodiments, associating the container type corresponding to the set sample container with the sample rack 10 and the placement position in the sample rack 10 includes associating the container type corresponding to the set sample container with the identification information corresponding to the sample rack 10 and the identification information corresponding to the placement position in the sample rack 10.

[0054] For example, the identification information corresponding to the sample rack 10 may be the sample rack number, or other identifiers or information used to identify the sample rack 10. Other information used to identify the sample rack 10 may be, for example, the color of the sample rack 10 itself. The identification information corresponding to the placement position may be the placement position number, or other identifiers or information used to identify the placement position. Other information used to identify the placement position may be, for example, the travel distance of the sample rack 10. The multiple placement positions of the sample rack 10 are arranged at intervals along the travel direction of the sample rack 10, and the specific placement position is determined according to the straight travel distance of the sample rack 10.

[0055] Please see Figure 3 , Figure 3 This is a schematic diagram of a settings interface provided in an embodiment of this application. Figure 3 As shown, the settings interface may include options for sample rack number, placement start, placement end, and sample container type, as well as buttons for adding, deleting, confirming, and exiting.

[0056] The sample rack number option allows you to select the corresponding number for various sample racks, such as routine, calibration, quality control, and emergency racks. You can fill in the number based on the existing numbers on the sample rack, such as the variation of the routine rack N0001. The selectable range is 1 to 999. The placement position start and end options can be checked from 1 to 10. The sample container type option specifies the container type used when requesting samples, such as "standard cup," "0.5ml microcup," or "2ml microcup." The "Add" button is used to add a new sample rack setting, such as adding sample rack N0001, position 1-5, and setting the container type to "0.5ml microcup." The "Delete" button is used to delete a sample rack setting. The "OK" button saves the settings. The "Exit" button exits the settings interface.

[0057] For example, such as Figure 3 As shown, when a user's parameter setting operation is detected for the sample rack number, placement position start, placement position end, and sample container type options in the settings interface, the parameter values ​​for each option are determined based on the parameter setting operation. For example, if the parameter value for the sample rack number option is N0001, the sample rack number is N0001; the parameter value for the placement position start option is 1; the parameter value for the placement position end option is 5; and the parameter value for the sample container type option is 0.5ml microcube, then the sample containers in placement positions 1-5 of the sample rack with sample rack number N0001 all correspond to the container type 0.5ml microcube. The settings interface also includes a confirm button. When a user triggers the confirm button, the container type corresponding to the set sample container is associated with the identification information corresponding to the sample rack and the identification information corresponding to the placement position in the sample rack. That is, the 0.5ml microcube is associated with the sample rack with sample rack number N0001 and placement positions 1-5 in the sample rack with sample rack number N0001 to obtain the association information.

[0058] The above embodiments associate the container type corresponding to the sample container with the identification information corresponding to the sample rack 10 and the identification information corresponding to the placement position in the sample rack 10. This association information can be saved without deletion. Subsequently, when identifying the container type corresponding to each placement position in the sample rack 10, the container type can be quickly and accurately retrieved based on the pre-associated association information, thereby enabling batch testing. For unconventional container types, such as micro-volume containers, there is no need to manually change the container type before each test. Therefore, this solves the problem in related technologies where users must manually change the type of each sample container sequentially before testing, leading to reduced sample testing efficiency. It eliminates the need for manual changes to the container type of each sample container, simplifying the operation and effectively improving sample testing efficiency.

[0059] In related technologies, when it is necessary to identify the container type corresponding to the sample container, it can be done through an image recognition device or an imaging device. However, for sample analyzers that are not equipped with an image recognition device or an imaging device, the method of this embodiment can be used to automatically and in batches perform aspiration operations on samples loaded in sample containers that are not the instrument's default sample containers, without having to manually change the container type before each sample aspiration. This is achieved by associating the container type corresponding to the sample container with the identification information corresponding to the sample rack 10 and the identification information corresponding to the placement position in the sample rack 10, and saving the association information.

[0060] Although some sample analyzers are equipped with image recognition or imaging devices, for special container types, such as bullet-shaped tubes used together with sample tubes, the image recognition or imaging devices may not be accurate. By associating the container type corresponding to the sample container with the identification information corresponding to the sample rack 10 and the identification information corresponding to the placement position in the sample rack 10, and saving the association information, it is helpful to avoid identification errors.

[0061] It should be noted that during sample testing, the height, shape, diameter, and sample volume of different container types vary, and the corresponding aspiration parameters also differ. In order to accurately aspirate samples from the container, it is necessary to first determine the container type and then determine the aspiration parameters based on the container type.

[0062] In some embodiments, controlling the sample needle to draw samples from the sample container and distribute at least a portion of the drawn samples to the reaction cup based on the association information may include: identifying the target sample holder to be tested, determining the target container type corresponding to the sample container where the sample to be drawn is located based on the first identification result and the association information, and controlling the sample needle to draw samples from the sample container and distribute at least a portion of the drawn samples to the reaction cup based on the target container type.

[0063] It should be noted that, for ease of description, the sample rack that needs to be tested can be defined as the target sample rack. The following will use the target sample rack as an example to explain how to determine the container type corresponding to the sample container in the target sample rack.

[0064] For example, the control device 50 can obtain the identification result corresponding to the target sample rack by scanning the barcode on the target sample rack, and record it as the first identification result. The first identification result may include the identification information corresponding to the target sample rack and the identification information corresponding to the placement positions within the target sample rack. For instance, the first identification result may include the sample rack number corresponding to the target sample rack and the position number corresponding to each placement position within the target sample rack.

[0065] For example, after identifying the target sample rack to be tested and obtaining the first identification result corresponding to the target sample rack, the target container type corresponding to the sample container where the sample to be absorbed is located can be determined based on the first identification result and the associated information.

[0066] In some embodiments, the control device 50 is used to determine the target container type corresponding to the sample container where the sample to be aspirated is located, based on the identification information corresponding to the target sample rack, the identification information corresponding to the placement position in the target sample rack, and the association information.

[0067] For example, if the associated information is: a 0.5ml microcup is associated with a sample rack numbered N0001 and placement positions 1-5 in the sample rack numbered N0001, and the sample rack number of the target sample rack is N0001, and the sample container containing the sample to be aspirated is placed in placement position 1, then it can be determined that the target container type corresponding to the sample container containing the sample to be aspirated is a 0.5ml microcup.

[0068] The above embodiments, by determining the target container type corresponding to the sample container where the sample to be collected is located based on the identification information corresponding to the target sample rack, the identification information corresponding to the placement position in the target sample rack, and the association information, can quickly and accurately determine the container type corresponding to the sample container where the sample to be collected is located in the target sample rack based on the association information, thereby effectively improving the testing efficiency of the sample.

[0069] After determining the target container type corresponding to the sample container containing the sample to be aspirated, the sample needle can be controlled to aspirate the sample from the sample container according to the target container type and distribute at least a portion of the aspirated sample to the reaction cup.

[0070] In some embodiments, controlling the sample needle to draw a sample from the sample container and dispense at least a portion of the drawn sample into the reaction cup according to the determined target container type may include: the control device 50 determining the aspiration parameters according to the target container type, and controlling the sample needle to draw a sample from the sample container and dispense at least a portion of the drawn sample into the reaction cup according to the aspiration parameters.

[0071] For example, aspiration parameters may include one or more of the following: liquid level detection threshold, liquid level detection algorithm, aspiration method, aspiration volume, and needle descent height. The liquid level detection algorithm refers to the algorithm used to detect the liquid level of the sample in the sample container; the liquid level detection threshold refers to the threshold used to detect the liquid level of the sample in the sample container; the aspiration method refers to the method used to control the sample needle to aspirate the sample from the sample container; the aspiration volume refers to the volume of sample aspirated by the sample needle from the sample container; and the needle descent height refers to the height the sample needle needs to descend when aspirating the sample.

[0072] For example, the aspiration parameters for constant volume containers and micro volume containers are different, and the aspiration parameters corresponding to the container type can be preset. The parameter values ​​for each parameter in the aspiration parameters can be set according to the actual situation, and the specific content is not limited here. The specific process of controlling the sample needle to draw the sample from the sample container and dispensing at least a portion of the drawn sample into the reaction cup according to the aspiration parameters can be found in related technologies, and the specific process is not limited here.

[0073] The above embodiments, by determining the aspiration parameters according to the target container type and controlling the sample needle to draw samples from the sample container and distribute at least a portion of the drawn samples to the reaction cup according to the aspiration parameters, can automatically control the sample needle to draw samples from the sample container and distribute at least a portion of the drawn samples to the reaction cup according to the target container type corresponding to the sample container, without requiring the user to manually set the aspiration parameters, thereby effectively improving the sample testing efficiency.

[0074] In this embodiment of the application, the sample analyzer further includes an imaging device for capturing images of the sample container. When controlling the sample needle to draw samples from the sample container and distribute at least a portion of the drawn samples to the reaction cup, in addition to determining the target container type corresponding to the sample container based on the identification result and associated information of the identified target sample rack, the target container type corresponding to the sample container can also be determined by combining the image of the sample container captured by the imaging device, the identification result of the target sample rack, and the associated information. This will be explained in detail below.

[0075] In some embodiments, controlling a sample needle to draw a sample from a sample container and distributing at least a portion of the drawn sample to a reaction cup based on association information includes: identifying the target sample holder to be tested to obtain a second identification result; performing image recognition on an image corresponding to the sample container to obtain a third identification result; determining the target container type corresponding to the sample container where the sample to be drawn is located based on the second identification result, the third identification result, and association information, and controlling the sample needle to draw a sample from the sample container and distributing at least a portion of the drawn sample to a reaction cup based on the target container type.

[0076] For example, the target sample frame to be tested can be identified first to obtain a second identification result.

[0077] In some implementations, the second identification result may be the same as the first identification result, that is, the second identification result includes the identification information corresponding to the target sample rack and the identification information corresponding to the placement position in the target sample rack.

[0078] In other embodiments, the second identification result is different from the first identification result. That is, in addition to including the identification information corresponding to the target sample rack and the identification information corresponding to the placement position in the target sample rack, the second identification result may also include other information, such as the container type to which the container belongs.

[0079] Container category refers to the classification of container types with different specifications. For example, multiple container types can be divided into two categories: major category containers and minor category containers. For instance, containers can be classified according to their specifications. A standard can be set, classifying containers with capacities greater than the standard as major category containers and those with capacities less than the standard as minor category containers. Furthermore, when a major category container is used with a minor category container, if the minor category container meets the criteria for the minor category container, then both the major and minor category containers are classified together as the minor category container.

[0080] For example, one classification method is shown in Table 1, where the container type corresponding to the sample container corresponds to a total capacity class, such as a major category container or a minor category container.

[0081] Table 1

[0082] Serial Number Container type Container Class 1 Containerless / 2 Ф13*75mm sample tube Major Containers 3 Ф13*100mm sample tube Major Containers 4 Hitachi 2ml Small category containers 5 Beckman Coulter 2ml Small category containers 6 Beckman Coulter 0.5ml Small category containers 7 Bullet head + Ф13*75mm sample tube Small category containers 8 Bullet head + Ф13*100mm sample tube Small category containers ……

[0083] It should be noted that the classification information of container types, that is, the correspondence between container types and container categories, is pre-stored in the control device 50 or in the storage module of the sample analyzer 1.

[0084] For example, such as Figure 4As shown, when determining the container type corresponding to the sample container containing the sample to be collected based on the second identification result, the third identification result, and the associated information, the specific steps may include:

[0085] Step S100: Determine whether the target sample rack is a dedicated sample rack based on the second identification result.

[0086] For example, based on the second identification result, it is determined whether the target sample rack is a dedicated sample rack. If the target sample rack is not a dedicated sample rack, step S101 is executed. If the target sample rack is a dedicated sample rack, steps S102 to S110 are executed.

[0087] Specifically, the second identification result includes the target sample rack's serial number information, which is used to determine whether the target sample rack is a dedicated sample rack. For example, if target sample racks numbered 1-99 are designated as dedicated sample racks, then if the target sample rack number in the second identification result is 100, the target sample rack is not a dedicated sample rack.

[0088] Step S101: Determine the container type corresponding to the sample container where the sample to be collected is located based on the third identification result.

[0089] For example, for sample container A, if the third identification result includes that sample container A is a Ф13*75mm sample tube, then it can be determined that the container type corresponding to sample container A is a Ф13*75mm sample tube.

[0090] Step S102: Determine whether the container type corresponding to the container type is a major category container based on the second identification result.

[0091] For example, based on the second identification result, the container type of the sample container on the target sample rack is confirmed to belong to the container general category. If the container general category to which the container type belongs is a major category container, then steps S103 to S105 are executed. If the container general category to which the container type belongs is not a major category container, then steps S106 to S110 are executed.

[0092] In one embodiment, determining the container type of the sample container on the target sample rack to which it belongs based on the second identification result includes: determining the container type of the sample container on the placement position based on the identification information corresponding to the target sample rack and the identification information corresponding to the placement position in the target sample rack, combined with the association information, and confirming the container type to which it belongs by combining the determined container type with the pre-stored classification information of the container type.

[0093] In this embodiment, the target sample rack to be tested is first identified to obtain a second identification result. Although the identification process only directly identifies the identification information corresponding to the target sample rack and the identification information corresponding to the placement position in the target sample rack, the container type to which the container belongs still needs to be confirmed by combining the association information and the classification information of the container type. However, it can be considered that the second identification result includes not only the identification information corresponding to the target sample rack and the identification information corresponding to the placement position in the target sample rack, but also the container type to which the container belongs.

[0094] Step S103: Determine whether the container type corresponding to the container type is a major category container based on the third identification result.

[0095] The container type is determined based on the third identification result, and then the classification information of the container type is combined to determine whether the container type belongs to the general category of containers.

[0096] If the target container type is determined to be a major container based on the third identification result, then step S104 is executed; if the target container type is determined to be a major container based on the third identification result, then step S105 is executed.

[0097] Step S104: Determine the container type corresponding to the sample container where the sample to be collected is located based on the third identification result.

[0098] For example, for sample container A, if the third identification result includes that sample container A is a Ф13*75mm sample tube, then the container type corresponding to sample container A can be determined to be a Ф13*75mm sample tube. That is, the container type determined by the third identification result is used as the final container type, and subsequent sampling operations are performed based on this container type.

[0099] Step S105: Determine the container type corresponding to the sample container where the sample to be collected is located based on the second identification result.

[0100] If the container type of the sample container is determined to be a major category based on the second identification result, but the container type of the sample container is determined to be a major category based on the third identification result, then the second identification result shall prevail.

[0101] In one embodiment, if the container type of the sample container is determined to belong to a major category based on the second identification result, but the container type of the sample container is determined to belong to a major category based on the third identification result, the second identification result shall prevail, but a default container type shall be set for the second identification result. That is, the container type corresponding to the sample container containing the sample to be collected is determined according to the default container type of the second identification result. The default container type may be a sample tube of a certain specification.

[0102] For example, if the container type of the sample container determined by the second identification result belongs to the general category of container, then the default container type is set to Ф13*75mm sample tube, and the subsequent sampling operation is performed based on the container type Ф13*75mm sample tube.

[0103] Step S106: Determine whether the container class corresponding to the container type is a subclass container based on the second identification result.

[0104] In step S102, if the container class corresponding to the container type is not a major category container, it means that the container class corresponding to the container type is a minor category container or the container class to which the container type belongs is not defined. In this case, steps S106 to S110 are executed.

[0105] For example, based on the second identification result, it is determined whether the container class corresponding to the container type is a subclass container. If the container class corresponding to the container type is a subclass container, then steps S107-S109 are executed; otherwise, step S110 is executed.

[0106] Step S107: Determine whether the container class corresponding to the container type is a subclass container based on the third identification result.

[0107] For example, if the container class corresponding to the container type is determined to be a minor container based on the third identification result, then step S108 is executed; if the container class corresponding to the container type is not a minor container based on the third identification result, then step S109 is executed.

[0108] Step S108: Determine the container type corresponding to the sample container where the sample to be absorbed is located based on the third identification result.

[0109] For example, for sample container B, if the third identification result includes that sample container B is a Beckman 2ml microtube, then it can be determined that the container type corresponding to sample container B is a Beckman 2ml microtube.

[0110] Step S109: Determine the container type corresponding to the sample container where the sample to be absorbed is located based on the second identification result.

[0111] If the container type of the sample container is determined to be a minor container based on the second identification result, but the container type of the sample container is determined to be a minor container based on the third identification result, then the second identification result shall prevail.

[0112] In one embodiment, if the container type of the sample container is determined to be a minor category container based on the second identification result, but the container type of the sample container is determined to be a minor category container based on the third identification result, the second identification result shall prevail, but a default container type shall be set for the second identification result. That is, the container type corresponding to the sample container containing the sample to be aspirated is determined according to the default container type of the second identification result. The default container type corresponding to the sample container is a microtube, microcup, or bullet-shaped container of a certain specification.

[0113] For example, if the container type of the sample container determined by the second identification result belongs to the sub-category container, then the default container type is set to Hitachi 2ml microtube, and subsequent sampling operations are based on the container type being Hitachi 2ml microtube.

[0114] Step S110: Based on the association information, determine the target container type corresponding to the sample container where the sample to be absorbed is located.

[0115] For example, the target container type corresponding to the sample container containing the sample to be aspirated can be determined based on the identification information corresponding to the target sample rack, the identification information corresponding to the placement position in the target sample rack, and the association information. For instance, for sample container C, which is placed in placement position 1 of target sample rack N0001, if the association information is: Ф13*100mm sample tube is associated with target sample rack number N0001 and placement position 1 in target sample rack number N0001, then the target container type corresponding to sample container C can be determined to be Ф13*100mm sample tube.

[0116] The above embodiments, by determining the target container type corresponding to the sample container where the sample to be aspirated is located based on the second identification result, the third identification result, and the associated information, can prevent the misjudgment problem that exists in determining the target container type solely based on the second or third identification result, and can further improve the accuracy of determining the container type, thereby improving the accuracy of controlling the sample needle to aspirate the sample from the sample container and distributing at least a portion of the aspirated sample to the reaction cup.

[0117] In some embodiments, the control device 50 is further configured to, in response to an association removal operation, remove the association between the container type on the settings interface and the sample rack 10 and the placement position in the sample rack. It should be noted that, in this embodiment, the user can remove the association between the container type and the sample rack 10 and the placement position in the sample rack via the delete button on the settings interface.

[0118] Please see Figure 5 , Figure 5 This is a schematic diagram of another settings interface provided in an embodiment of this application. For example... Figure 5 As shown, when a user triggers the delete button on the row containing sample rack number N0002, the association between the container type and sample rack N0002 and the placement position in sample rack N0002 can be severed.

[0119] The above embodiments, by responding to the association removal operation, remove the association between the container type on the settings interface and the sample rack and the placement position in the sample rack, making it convenient for users to remove unnecessary associations in batches. The operation is simple and convenient, thereby improving the user experience.

[0120] Please see Figure 6 , Figure 6 This is a schematic flowchart of a control method for a sample analyzer provided in an embodiment of this application. The control method for the sample analyzer may include the following steps S201 to S203.

[0121] Step S201: Display at least one set of selectable objects on the settings interface of the sample analyzer. The at least one set of selectable objects includes the sample rack number option, the placement position start option, the placement position end option, and the sample container type option.

[0122] For example, such as Figure 7 As shown, the settings interface can include three sets of selectable objects. Each set of selectable objects includes a sample rack number option, a placement position start option, a placement position end option, and a sample container type option.

[0123] Step S202: In response to parameter setting operations on at least one set of selectable objects, determine the parameter values ​​for the sample rack number option, placement start option, placement end option, and sample container type option.

[0124] It should be noted that users can associate the container type and placement position of the sample container with each set of selectable objects, thereby linking the container type of the sample container with the identification information of the sample rack and the identification information of the placement position in the sample rack.

[0125] For example, such as Figure 8 As shown, when a user's parameter setting operation on the second group of selectable objects is detected, the parameter values ​​for the sample rack number option, placement start option, placement end option, and sample container type option are determined based on the parameter setting operation. For example, the sample rack number is N0002, the placement start number is 6, the placement end number is 8, and the container type is Ф13*100mm sample tube.

[0126] Step S203: In response to the save operation of at least one set of selectable objects, associate the parameter values ​​of the sample rack number option, the placement position start option, the placement position end option, and the sample container type option to obtain association information, and save the association information.

[0127] It should be noted that after setting the association between the container type and the placement location of the sample container, the user needs to save the settings for the association to take effect.

[0128] For example, such as Figure 9 As shown, the settings interface includes an "OK" button. Users can click the "OK" button to save the association information between the sample container type and its placement position. When a user saves the selected object in the settings interface, the parameter values ​​of the sample rack number option, placement position start option, placement position end option, and sample container type option are associated to obtain association information, which is then saved. For example, the association information is: Ф13*100mm sample tubes are associated with sample rack number N0002 and placement positions 6-8 within sample rack number N0002.

[0129] The above embodiments, by responding to parameter setting operations on at least one set of selectable objects, associate the container type corresponding to the set sample container with the sample rack and the placement position in the sample rack. This enables batch setting of the sample rack and placement position with the container type corresponding to the sample container, solving the problem in related technologies where users have to manually change the type of each sample container sequentially, which reduces the testing efficiency of the samples. It eliminates the need to manually change the container type of each sample container sequentially, making the operation simple and convenient, and effectively improving the testing efficiency of the samples.

[0130] In some embodiments, the settings interface further includes adding new options; the control method of the sample analyzer may further include: in response to the triggering operation of adding new options, adding a set of selectable objects to the settings interface, the selectable objects including sample rack number option, placement position start option, placement position end option, and sample container type option.

[0131] For example, such as Figure 10 As shown, when a user triggers an action on a new option in the settings interface, a set of selectable objects can be added to the design interface based on the trigger action. These selectable objects include a sample rack number option, a placement position start option, a placement position end option, and a sample container type option. This allows the user to associate the container type corresponding to the sample container with the sample rack and its placement position to obtain association information. For example, Beckman 2ml sample tubes can be associated with sample rack number N0004 and placement positions 1-10 within sample rack number N0004.

[0132] In the above embodiments, by responding to the triggering operation of adding new options, a new set of selectable objects is added to the settings interface, which makes it easier for users to add sample racks with the required container type according to actual batch testing needs, thereby improving efficiency and thus improving the user experience.

[0133] In some embodiments, the settings interface further includes at least one delete option, each delete option corresponding to a set of selectable objects; the control method of the sample analyzer further includes: in response to a trigger operation on a delete option in the settings interface, deleting a set of selectable objects corresponding to the triggered delete option.

[0134] For example, such as Figure 11 As shown, when a user triggers a delete option on the settings interface, a set of selectable objects corresponding to the triggered delete option can be deleted based on the trigger operation. For example, when a user triggers a delete button on the row containing sample rack number N0003, the association between the 0.5ml micrometer cup, sample rack number N0003, and placement positions 1-5 within sample rack number N0003 can be severed.

[0135] The above embodiments, by responding to the triggering operation of the delete option, decouple the container type on the settings interface from the sample rack and the placement position in the sample rack, making it easy for users to decouple unnecessary relationships. The operation is simple and convenient, thereby improving the user experience.

[0136] Please see Figure 12 , Figure 12 This is a schematic flowchart of another control method for a sample analyzer provided in the embodiments of this application. The control method for the sample analyzer may include the following steps S301 to S304.

[0137] Step S301: Identify the target sample rack where the sample to be collected is located to obtain the fourth identification result.

[0138] For example, the sample rack where the current sample to be collected is located can be identified as the target sample rack. By scanning the barcode on the target sample rack, the identification result corresponding to the target sample rack can be obtained, which is recorded as the fourth identification result.

[0139] In some embodiments, the fourth identification result may include identification information corresponding to the target sample rack and identification information corresponding to the placement positions within the target sample rack. For example, the fourth identification result may include the sample rack number corresponding to the target sample rack and the position number corresponding to each placement position within the target sample rack.

[0140] In one embodiment, the fourth identification result may include the sample rack number corresponding to the target sample rack and the travel distance of the target sample rack, which corresponds to the placement position of the target sample rack.

[0141] In other embodiments, the fourth identification result may include, in addition to the identification information corresponding to the target sample rack and the identification information corresponding to the placement position in the target sample rack, the container type to which the container belongs.

[0142] The container type to which a container belongs can be determined based on the identification information corresponding to the target sample rack, the identification information corresponding to the placement position in the target sample rack, the association information, and the classification information of the container type. The determination method is the same as the second identification result, and will not be repeated here.

[0143] Step S302: Perform image recognition on the image of the sample container corresponding to the placement position in the target sample rack acquired by the imaging device to obtain the fifth recognition result.

[0144] For example, images of sample containers corresponding to the placement positions in the target sample rack can be acquired using the imaging device on the sample analyzer, and image recognition algorithms can be used to perform image recognition on the images of the sample containers to obtain a fifth recognition result. The fifth recognition result includes the container type corresponding to each placement position in the target sample rack, and may also include the container category to which the container type belongs.

[0145] In one embodiment, the container type is obtained based on image recognition, and then the container category corresponding to the container type is confirmed based on classification information. This method also belongs to the fifth identification result, which includes the container type corresponding to the sample container in each placement position in the target sample rack, and may also include the container category to which the container type belongs.

[0146] Step S303: Obtain the target sample rack and the association information between the placement position and the container type in the target sample rack. Based on the association information, the fourth identification result and the fifth identification result, determine the target container type corresponding to the sample container in each placement position in the target sample rack.

[0147] For example, after obtaining the fourth and fifth identification results, the target sample rack and the association information between the placement position and the container type in the target sample rack can be obtained. Based on the association information, the fourth and fifth identification results, the target container type corresponding to the sample container in each placement position in the target sample rack can be determined.

[0148] In some embodiments, before obtaining the association information between the target sample rack and the placement position in the target sample rack and the container type, the method further includes: in response to the parameter setting operation of the target sample rack, associating the container type corresponding to the set sample container with the target sample rack and the placement position in the target sample rack to obtain association information.

[0149] For example, such as Figure 3 As shown, when a user's parameter setting operation for the sample rack number option, placement position start option, placement position end option, and sample container type option is detected, the parameter values ​​for each of the sample rack number option, placement position start option, placement position end option, and sample container type option are determined according to the parameter setting operation.

[0150] The above embodiments, by associating the container type corresponding to the set sample container with the identification information corresponding to the sample rack and the placement position in the sample rack, can achieve the pre-setting of the association between the sample rack and the placement position and the container type corresponding to the sample container, and save the association information. This solves the problem in related technologies where users manually change the type of each sample container sequentially, leading to reduced sample testing efficiency. It eliminates the need to manually change the container type of each sample container before each test, making the operation simple and convenient, and effectively improving sample testing efficiency. Furthermore, when identifying the container type corresponding to each placement position in the sample rack subsequently, the container type corresponding to each placement position in the sample rack can be quickly and accurately retrieved based on the predefined association information, thereby effectively improving sample testing efficiency.

[0151] In some embodiments, the fourth identification result includes whether the target sample rack is a preset dedicated sample rack; determining the target container type corresponding to the sample container in each placement position of the target sample rack based on the association information, the fourth identification result, and the fifth identification result may include: if the target sample rack is determined not to be a dedicated sample rack based on the fourth identification result, then the target container type corresponding to the sample container in each placement position is determined according to the fifth identification result; if the target sample rack is determined to be a dedicated sample rack based on the fourth identification result, and the fourth identification result also includes the first container category to which the target container type belongs, then the target container type corresponding to the sample container in each placement position is determined according to the fifth identification result and the first container category to which the target container type belongs; if the target sample rack is determined to be a dedicated sample rack based on the fourth identification result, and the fourth identification result does not include the first container category to which the target container type belongs, then the target container type corresponding to the sample container in each placement position is determined according to the association information.

[0152] It should be noted that, in this embodiment, when the target sample rack is not a dedicated sample rack, the target container type corresponding to the sample container is directly determined based on the fifth recognition result obtained from image recognition; when the target sample rack is a dedicated sample rack and the fourth recognition result does not include the first container category to which the target container type belongs, the target container type corresponding to the sample container is determined based on the association information corresponding to the target sample rack; when the target sample rack is a dedicated sample rack and the fourth recognition result includes the first container category to which the target container type belongs, it is further determined whether the first container category to which the target container type belongs matches the second container category to which the target container type belongs in the fifth recognition result. If they match, the target container type corresponding to the sample container is determined based on the container type to which the sample container belongs in the fifth recognition result; if they do not match, the target container type corresponding to the sample container is determined based on the default container type corresponding to the first container category. The following will provide a detailed explanation of each situation.

[0153] In some embodiments, the fifth identification result includes the container type to which the sample container in each placement position belongs; determining the target container type corresponding to the sample container in each placement position based on the fifth identification result includes: determining the target container type corresponding to each sample container based on the container type of the sample container in each placement position in the fifth identification result.

[0154] For example, when it is determined based on the fourth identification result that the target sample rack is not a dedicated sample rack, the target container type corresponding to each sample container can be determined according to the container type in the fifth identification result for each sample container in each placement position. For example, for sample container A in placement position 1, if the fifth identification result includes that sample container A in placement position 1 is a Ф13*75mm sample tube, then the target container type corresponding to sample container A can be determined to be a Ф13*75mm sample tube.

[0155] In some embodiments, the fifth identification result includes the second container class to which the container type belongs and the container type to which the sample container in each placement position belongs; determining the target container type corresponding to the sample container in each placement position based on the fifth identification result and the first container class to which the container type belongs includes: if the first container class to which the target container type belongs matches the second container class, then determining the target container type corresponding to each sample container based on the container type of the sample container in each placement position in the fifth identification result; if the first container class to which the target container type belongs does not match the second container class, then determining the target container type corresponding to each sample container based on the default container type corresponding to the first container class.

[0156] For example, when both the first and second container categories are classified as major or minor categories, the target sample rack is determined to match the first and second container categories. In this case, the target container type for each sample container can be determined based on the container type in the fifth identification result for each placement position. For instance, for sample container B in placement position 2, if the fifth identification result includes that sample container B in placement position 2 is a Ф13*75mm sample tube, then the target container type corresponding to sample container B can be determined to be a Ф13*75mm sample tube.

[0157] For example, when the first container category is a major category container and the second container category is a minor category container, or vice versa, it is determined that the first and second container categories to which the target sample rack belongs do not match. In this case, the target container type corresponding to each sample container can be determined based on the default container type corresponding to the first container category. For instance, if the target container type belongs to a major category container, and the default container type corresponding to a major category container is a Ф13*75mm sample tube, then the target container type corresponding to the sample container can be determined to be a Ф13*75mm sample tube. As another example, if the target container type belongs to a minor category container, and the default container type corresponding to a minor category container is a Hitachi 2ml sample tube, then the target container type corresponding to the sample container can be determined to be a Hitachi 2ml sample tube.

[0158] In some embodiments, if the target sample rack is determined to be a dedicated sample rack based on the fourth identification result, and the fourth identification result does not include the first container category to which the target sample rack belongs, then the target container type corresponding to the sample container in each placement position is determined according to the identification information corresponding to the target sample rack, the identification information corresponding to the placement position in the target sample rack, and the association information.

[0159] For example, for sample container C, which is placed in position 1 of the target sample rack N0001, if the association information is: the Ф13*100mm sample tube is associated with the target sample rack with sample rack number N0001 and position 1 of the target sample rack with sample rack number N0001, then it can be determined that the target container type corresponding to sample container C is the Ф13*100mm sample tube.

[0160] The above embodiments, by determining the target container type corresponding to each placement position of the sample container in the target sample rack based on the association information, the fourth identification result, and the fifth identification result, can avoid misjudgment in determining the target container type of the sample container solely based on the fifth identification result, and can effectively improve the accuracy of detecting the container type of the sample container.

[0161] In this embodiment of the application, after the user places the sample container on the sample rack, container type correction processing can also be performed, that is, the sample container that is placed in the wrong position can be identified and a prompt can be given. The following will explain in detail how to perform container type correction processing.

[0162] In some embodiments, after determining the target container type corresponding to the sample container in each placement position of the target sample rack based on the association information, the fourth identification result, and the fifth identification result, the method further includes: when the target container type corresponding to the sample container in the determined placement position is inconsistent with the container type associated with the corresponding placement position in the association information, an alarm prompt is output, and the alarm prompt is used to indicate that the sample container is placed incorrectly.

[0163] In the above embodiments, when the target container type corresponding to the sample container in the determined placement position is inconsistent with the container type associated with the corresponding placement position in the association information, an alarm prompt is output. This enables container type error correction, timely prompts the user that the sample container has been placed incorrectly, avoids abnormalities in subsequent sample detection, and thus improves the accuracy of sample detection and enhances the user experience.

[0164] Step S304: According to the target container type corresponding to each sample container, control the sample needle to draw the sample from the sample container and distribute at least a portion of the drawn sample to the reaction cup, and control the detection device to detect the test liquid containing the sample in the reaction cup to obtain the detection result.

[0165] For example, after determining the target container type for each sample container, aspiration parameters can be determined based on the target container type. These parameters are then used to control the sample needle to draw samples from the sample container and distribute at least a portion of the drawn sample to the reaction cup. The detection device is then controlled to detect the sample-containing test liquid in the reaction cup to obtain the detection result. The aspiration parameters may include one or more of the following: liquid level detection threshold, liquid level detection algorithm, aspiration method, aspiration volume, and needle descent height.

[0166] For example, constant volume containers (e.g., sample tubes) and micro-volume containers (e.g., microcapsules, bullet-shaped containers) have different aspiration parameters, which can be preset according to the container type. The parameter values ​​for each parameter in the aspiration parameters can be set according to the actual situation, and the specific content is not limited here. The specific process of controlling the sample needle to draw the sample from the sample container and dispensing at least a portion of the drawn sample into the reaction cup according to the aspiration parameters can be found in related technologies, and the specific process is not limited here.

[0167] The above embodiments, by determining the aspiration parameters according to the target container type and controlling the sample needle to draw samples from the sample container and distribute at least a portion of the drawn samples to the reaction cup according to the aspiration parameters, can automatically control the sample needle to draw samples from the sample container and distribute at least a portion of the drawn samples to the reaction cup according to the target container type corresponding to the sample container, without requiring the user to manually set the aspiration parameters, thereby effectively improving the sample testing efficiency.

[0168] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
