Figure 2 FIG. 1 is a schematic diagram of another embodiment of the sample analysis system provided by the present application. Figure 1 As shown, the sample analysis system of the embodiment of the present application includes a sample injection unit 10 , a first analysis unit 20 , a second analysis unit 30 and an information processing unit 40 .

[0025] Specifically, the first analysis unit 20 and the second analysis unit 30 can be understood as two detection devices provided by the sample analysis system, which are used to process and / or analyze the sample to be tested in different working modes. Among them, the working mode may include a detection mode and a pre-dilution mode. In one embodiment, the first analysis unit 20 is used to pre-dilution the sample to be tested in the pre-dilution mode, and the second analysis unit 30 is used to detect and analyze the sample to be tested in the preset detection mode; in another embodiment, the first analysis unit 20 can be used to pre-dilution the sample to be tested in the pre-dilution mode, the first analysis unit 20 can also be used to detect and analyze the sample to be tested in the detection mode, and the second analysis unit 30 is used to detect and analyze the sample to be tested in the detection mode. At this time, the detection modes of the first analysis unit 20 and the second analysis unit 30 are different. Among them, at least one of the first analysis unit 20 and the second analysis unit 30 can be a blood analyzer.

[0026] For example, the first analysis unit 20 can be used to perform a routine blood test on the sample to be tested, and the second analysis unit 30 can be used to perform a specific protein test on the sample to be tested; the routine blood test includes at least one of WBC (White Blood Cell) test, HGB (Hemoglobin) test, RBC (red blood cell) test, DIFF (DIFFerential, five classifications of white blood cells) test or RET (reticulocyte, reticulocyte count) test, and PLT (Blood Platelet, platelet count) test; the specific protein test includes SAA (serum amyloidA protein, serum amyloid protein A), CRP (C-reactive At least one of C-reactive protein (C-reactive protein), TRF (tramsferrin), Hs-CRP (high-sensitivity C-reactive protein), PCT (procalcitonin) and D-Dimer (D-dimer); or, the first analysis unit 20 is used to perform blood routine detection and / or specific protein detection on the sample to be tested, and the second analysis unit 30 is used to perform immunoassay and / or glycation detection on the sample to be tested. The detection mode of the analysis unit is not limited here and can be set according to actual needs.

[0027] The sample injection unit 10 is used to obtain and carry the sample tube to be diluted, and move the sample tube to be diluted to the first analysis unit 20. Figure 2 As shown, the sample injection unit 10 may include an identification mechanism and a conveying mechanism 110, the conveying mechanism 110 is used to convey the sample rack, so that the sample rack moves to a preset position along the conveying direction of the conveying mechanism 110; the identification mechanism, the first analysis unit 20, and the second analysis unit 30 are sequentially arranged on one side of the conveying mechanism 110 along the conveying direction. Further, the sample injection unit 10 may also include a sample injection mechanism 120, and one end of the conveying mechanism 110 is provided with a sample injection area and an unloading area for placing samples. In response to the sample rack being placed in the sample injection area, the information processing unit 40 controls the sample injection unit 10 to start the automatic injection process, so that the sample injection mechanism 120 pushes the sample rack in the sample injection area to the conveying mechanism 110, and the conveying mechanism 110 moves the sample rack to the first analysis unit 20 and / or the second analysis unit 30 in sequence along the conveying direction. That is, the sample injection unit 10 of the embodiment of the present application is used to realize the functions of sample injection, scheduling, and unloading of sample racks and sample tubes.

[0028] The information processing unit 40 is connected to the first analysis unit 20, the second analysis unit 30 and the injection unit 10 respectively, and is used to obtain the ratio information of the sample tube to be diluted, and is also used to transmit the ratio information to the first analysis unit to instruct the first analysis unit 20 to perform a pre-dilution operation on the sample tube to be diluted according to the ratio information to prepare the sample to be tested. The information processing unit 40 can be an electronic chip with signal processing capability on the sample analysis system, and is used to perform information processing according to the data stored and exchanged between the analysis unit, the injection unit and the central processing unit, so that the analysis unit can realize the above-mentioned detection and analysis of the sample.

[0029] In one embodiment, the first analysis unit 20 only supports the pre-dilution mode, at which time, the first analysis unit 20 returns the prepared sample to be tested to the injection unit 10, and the injection unit 10 moves the sample to be tested to the second analysis unit 30 for sample analysis. In another embodiment, the first analysis unit 20 supports the pre-dilution mode and the detection mode. After the sample to be tested is prepared, the information processing unit 40 instructs the first analysis unit 20 and / or the second analysis unit 30 to analyze the sample to be tested according to the detection items of the sample to be tested. For example, the information processing unit 40 instructs the first analysis unit 20 to analyze the sample to be tested in response to the detection items of the sample to be tested after pre-dilution need to be completed on the first analysis unit 20, and / or, the information processing unit 40 instructs the first analysis unit 20 to return the sample to be tested to the injection unit 10 in response to the detection items of the sample to be tested after pre-dilution completed on the second analysis unit 30, and the injection unit 10 moves the sample to be tested to the second analysis unit 30 for sample analysis.

[0030] Further, the sample tube to be diluted may be a sample tube type that is defined by a user or a transfer mechanism when transferring a trace blood sample from a sampling tube to a sample tube of a specific shape or specific mark and that needs to be pre-diluted. For example, the user or the transfer mechanism transfers the trace blood sample to the sample tube to be diluted, and places the sample tube to be diluted on a sample rack to move the sample rack to the sampling area of ​​the injection unit 10, so that the injection unit 10 obtains the sample tube to be diluted; or, the sample tube to be diluted may be a sampling tube for collecting and storing trace blood samples. In response to the sample tube to be diluted being received, the injection unit 10 moves the sample tube to be diluted to the first analysis unit 20, so that the first analysis unit 20 performs a pre-dilution operation on the sample to be diluted according to the ratio information of the sample tube to be diluted, so as to obtain the sample to be tested.

[0031] In the embodiment of the present application, the sample analysis system obtains the ratio information of the sample tube to be diluted through the information processing unit 40, and controls the first analysis unit 20 to pre-dilute the sample to be diluted in the sample tube to be diluted according to the ratio information to obtain the sample to be tested, so that the first analysis unit 20 and / or the second analysis unit 30 detect the pre-diluted sample to be tested. Therefore, the sample analysis system of this embodiment can support the automatic test process such as the injection, pre-dilution operation, and detection of the sample to be diluted, without manual dilution ratio, so that the sample analysis system can be applied to high-speed detection scenarios with large sample volumes, improve the analysis efficiency of the sample to be diluted, and reduce labor costs.

[0032] Optionally, the injection unit 10 is used to transfer a sample rack carrying multiple sample tubes and obtain the type of the transferred sample rack. The information processing unit 40 is also used to mark the sample tubes of the sample rack as sample tubes to be diluted in response to the type of the sample rack being a pre-dilution sample rack, and control the injection unit 10 to move the sample tubes to be diluted to the first analysis unit 20.

[0033] Specifically, in one embodiment, after the user or the transfer mechanism transfers the trace blood sample to the sample tube to be diluted, the sample tube to be diluted is placed in a pre-dilution sample rack with a specific identification, and the sample injection unit 10 is used to obtain the sample rack from the injection area and transfer the sample rack to a preset position. The sample injection unit 10 is also used to identify the identification of the sample rack through the first identification mechanism during the transmission process, wherein the specific identification may include identification data such as an identification code and a two-dimensional code that stores preset information. The information processing unit 40 is used to define the sample rack as a pre-dilution sample rack when the identification of the sample rack is a specific identification, and mark the sample tube of the pre-dilution sample rack as a sample tube to be diluted, so as to control the sample injection unit 10 to move the sample tube to be diluted to the first analysis unit 20 for pre-dilution operation.

[0034] Further, after the first analysis unit 20 performs a pre-dilution operation on the sample to be diluted and prepares the sample to be tested, in one embodiment, the information processing unit 40 directly controls the first analysis unit 20 and / or the second analysis unit 30 to analyze the sample to be tested according to the detection items of the sample to be tested. For example, the information processing unit 40 controls the first mixing mechanism of the first analysis unit 20 to mix the sample to be tested in response to the detection items of the sample to be tested needing to be completed on the first analysis unit 20, so that the first analysis unit 20 directly analyzes the mixed sample to be tested, and / or, the information processing unit 40 controls the injection unit 10 to move the sample to be tested to the second analysis unit 30 in response to the detection items of the pre-diluted sample to be tested being completed on the second analysis unit 30, and the second mixing mechanism of the second analysis unit 30 mixes the sample to be tested, so that the second analysis unit 30 directly analyzes the mixed sample to be tested. The sample analysis system of this embodiment sequentially performs pre-dilution operation and analysis processing on the sample to be diluted in the pre-dilution sample rack until all sample tubes of the pre-dilution sample rack currently injected are analyzed.

[0035] In another embodiment, the information processing unit 40 controls the first analysis unit 20 to sequentially perform pre-dilution operations on all sample tubes to be diluted in the pre-dilution sample rack currently injected, so as to obtain a number of pre-dilution sample tubes to be tested. After the pre-dilution of all sample tubes in the pre-dilution sample rack is completed, the information processing unit 40 moves the pre-dilution samples to be tested to the first analysis unit 20 and / or the second analysis unit 30 that need to be tested in a preset order, until the analysis of all sample tubes in the pre-dilution sample rack currently injected is completed. That is, the sample analysis system of this embodiment performs pre-dilution operations on the sample tubes of the pre-dilution sample rack in the first stage, and performs analysis operations on the sample tubes of the pre-dilution sample rack in the second stage.

[0036] In an embodiment of the present application, when starting the injection process of the pre-dilution sample rack, the user can input the ratio information of the sample to be diluted for this injection through the visual interface of the sample analysis system, so as to batch inject multiple sample tubes to be diluted through the pre-dilution sample rack. The first analysis unit 20 performs pre-dilution operation on the multiple sample tubes to be diluted in the pre-dilution sample rack, thereby realizing the pre-dilution assembly line operation, facilitating the user to centrally sort trace blood samples, improving the pre-dilution efficiency, and facilitating the sample analysis system to process and analyze large batches of samples.

[0037] Optionally, the injection unit 10 is used to transfer a sample rack carrying multiple sample tubes and obtain the type of the transferred sample tubes. The information processing unit 40 is also used to control the injection unit 10 to move the sample tube to be diluted to the first analysis unit 20 for pre-dilution operation in response to the sample tube being a sample tube to be diluted.

[0038] Specifically, in another embodiment, after the user or the transfer mechanism transfers the trace blood sample to the sample tube to be diluted, the sample tube to be diluted is placed in the sample rack on the injection area of ​​the injection unit 10. The injection unit 10 is used to obtain the sample rack from the injection area and transfer the sample rack to a preset position. The injection unit 10 is also used to identify the identification code, shape, color, specification, etc. of the sample tube through the first recognition mechanism during the transmission process to determine whether the type of the sample tube to be injected is the sample tube to be diluted. Exemplarily, the sample tube to be diluted has a different structure and / or shape from other sample tubes, and the first recognition mechanism determines whether the sample tube is the sample tube to be diluted by capturing an image of the acquired sample tube.

[0039] Furthermore, the sample tube to be diluted may also be provided with a plurality of sample tube colors or specifications. The first identification mechanism identifies the color or specification of the sample tube to be diluted to obtain the matching information of the sample tube to be diluted. The matching information may include the sample volume information and the dilution ratio of the sample to be diluted, so that the first analysis unit 20 performs pre-dilution operation on the sample tube to be diluted according to the matching information.

[0040] Therefore, in this embodiment, the sample analysis system transmits and identifies the sample tube to be diluted through the sampling unit 10 to obtain the type of the transmitted sample tube, so that the information processing unit 40 controls the sampling unit 10 to move the sample tube to be diluted to the first analysis unit 20 in response to the type of the sample tube being the sample tube to be diluted. The first analysis unit 20 performs a pre-dilution operation on the sample tube to be diluted, thereby realizing fully automatic testing such as automatic sampling, pre-dilution, and detection of the sample analysis system. There is no need for manual dilution ratio, and the pre-dilution operation is more accurate, thereby improving the analysis efficiency of the sample to be diluted and reducing labor costs.

[0041] Optionally, the sample analysis system also includes a visualization interface (not shown), which is connected to the information processing unit 40. The information processing unit 40 is used to receive a first operation instruction from the user on the visualization interface through the visualization interface, so as to obtain the ratio information of the sample tube to be diluted from the first operation instruction, and the ratio information includes the dilution ratio and sample volume information of the sample to be diluted.

[0042] Specifically, the visualization interface can be a display device for displaying and obtaining the first operation instruction. The display device can be set on the sample analysis system or connected to the sample analyzer of the sample analysis system through a corresponding interface. The display device can be equipped with a software system for operating and controlling the sample analyzer, so that the user can perform injection settings or pre-dilution settings on the software system of the visualization interface. In an optional embodiment, the user can interact with the visualization interface through devices such as a mouse, keyboard, and control buttons to generate the first operation instruction, or the user can interact with the visualization interface through voice input instructions to generate the first operation instruction, or the user can also interact with the display device to generate the first operation instruction, so that the information processing unit 40 obtains the ratio information of the sample tube to be diluted from the first operation instruction.

[0043] In an embodiment of the present application, the user performs pre-dilution settings through a visual interface, so that the information processing unit 40 obtains the ratio information of the sample tube to be diluted from the first operation instruction of the visual interface, and the first analysis unit 20 performs pre-dilution operations on the sample tube to be diluted according to the ratio information, thereby realizing fully automatic testing such as automatic sampling, pre-dilution, and detection of the sample analysis system. There is no need for manual dilution ratio, and the pre-dilution operation is more accurate, thereby improving the analysis efficiency of the sample to be diluted and reducing labor costs.

[0044] Optionally, the first analysis unit 20 includes a dilution mechanism (not shown) and a first mixing mechanism (not shown), the dilution mechanism being used to add diluent to the sample tube to be diluted according to the dilution ratio of the matching information, the information processing unit 40 being used to mark the sample tube to be diluted as a pre-diluted sample tube to be tested in response to the diluent having been added to the sample tube to be diluted, and the first mixing mechanism being used to perform a mixing operation on the pre-diluted sample tube to be tested, so that the diluted sample in the pre-diluted sample tube to be tested is mixed with the diluent and a mixed sample to be tested is obtained.

[0045] Specifically, the dilution mechanism may include a diluent storage device and an injection needle. The diluent storage device is used to store the diluent, and the injection needle is connected to the diluent storage device. After obtaining the matching information, the information processing unit 40 calculates the volume of the diluent that needs to be added to the sample tube to be diluted according to the dilution ratio of the matching information and the sample volume information of the sample to be diluted, so as to control the injection needle to add a preset volume of the diluent to the sample tube to be diluted.

[0046] In response to the diluent being added to the sample tube to be diluted, the information processing unit 40 marks the sample tube to be diluted as a pre-diluted sample tube to be tested. It can be understood that the sample tube to be diluted is a state where the information processing unit 40 marks the processed sample tube as needing to be pre-diluted, and the pre-diluted sample tube to be tested is a state where the information processing unit 40 marks the sample tube as having performed the pre-dilution operation and waiting to be tested. The information processing unit 40 marks the status of sample tubes in different test processes, so that the sample analysis system can perform corresponding operations on differently marked sample tubes. For example, when performing injection tests on multiple sample tubes to be diluted through the pre-dilution sample rack, the first analysis unit 20 is used to perform pre-dilution operations on the sample tube to be diluted, and the information processing unit 40 is used to control the first analysis unit 20 and / or the second analysis unit 30 to test the pre-diluted sample tube to be tested after the pre-dilution is completed, so as to realize the assembly line test of the sample analysis system.

[0047] After the dilution mechanism adds the diluent to the sample tube to be diluted, the information processing unit 40 is also used to control the first mixing mechanism to perform a mixing operation on the pre-diluted sample tube to be tested, so that the sample to be diluted in the pre-diluted sample tube to be tested is mixed with the diluent and a mixed sample to be tested is obtained, so that the blood cells of the mixed sample to be tested can be evenly distributed to ensure the accuracy of the test. Specifically, the first mixing mechanism is used to mix the liquid in the pre-diluted sample tube to be tested, and the first mixing mechanism can be provided with a mechanical gripper for grabbing the pre-diluted sample tube to be tested and mixing it according to a preset posture, or the first mixing mechanism can be an eccentric mixing mechanism for driving the bottom of the pre-diluted sample tube to be tested to reciprocate within a preset range, so as to enhance the mixing effect of the sample to be diluted and the diluent in the pre-diluted sample tube to be tested, and ensure the accuracy of the pre-diluted sample tube to be tested when it is tested on the machine.

[0048] In the embodiment of the present application, the information processing unit 40 is used to control the dilution mechanism to add a preset volume of diluent to the sample tube to be diluted, and is also used to control the first mixing mechanism to perform a mixing operation on the pre-diluted sample tube to be tested in response to the diluent having been added to the sample tube to be diluted, so that the diluted sample in the pre-diluted sample tube to be tested reacts with the diluent and obtains the reacted sample to be tested, thereby realizing fully automatic testing such as automatic sampling, pre-dilution, and detection of the sample analysis system without the need for manual dilution and matching.

[0049] Further, the second analysis unit 30 may also include a second mixing mechanism, and the mixing method / structure of the second mixing mechanism may be similar to that of the first mixing mechanism, which will not be described in detail here. In one embodiment, after the first analysis unit 20 pre-dilutes the sample to be diluted, the information processing unit 40 controls the first mixing mechanism to mix the sample to be tested in response to the need for the pre-diluted sample tube to be detected to be analyzed in the first analysis unit 20, so that the first analysis unit 20 directly analyzes the mixed sample to be tested. In response to the need for the pre-diluted sample tube to be detected to be analyzed in the second analysis unit 30, the information processing unit 40 does not control the first mixing mechanism to mix the sample to be tested for the second time, but directly controls the injection unit 10 to move the sample to be tested to the second analysis unit 30, so that the second analysis unit 30 continues to add the corresponding reagent to the sample to be tested according to the detection requirements of the sample to be tested, and mixes the sample to be tested after the second addition of the reagent through the second mixing mechanism, and the second analysis unit 30 analyzes the mixed sample to be tested.

[0050] Optionally, the information processing unit 40 is used to obtain the detection items of the sample tube to be diluted. The information processing unit 40 is also used to obtain the detection items of the pre-diluted sample tube to be tested in response to the sample tube to be diluted being marked as the pre-diluted sample tube to be tested, so as to instruct the first analysis unit 20 to test the pre-diluted sample tube to be tested according to the detection items, and / or control the injection unit 10 to move the pre-diluted sample tube to be tested to the second analysis unit 30 according to the detection items, so that the second analysis unit 30 tests the pre-diluted sample tube to be tested according to the detection items.

[0051] Specifically, in one embodiment, the sample injection unit 10 includes a first identification mechanism (not shown), which is used to capture images of the sample tube to be diluted, so as to identify the identification code of the sample tube to be diluted and obtain sample information of the sample tube to be diluted, and the sample information may store sampling information (sampling time and sampling location, etc.) of the sample tube to be diluted, identity information of the sample to be tested, test items required for the sample to be tested, etc. The information processing unit 40 obtains the test items of the sample tube to be diluted from the sample information, so as to control the first analysis unit 20 and / or the second analysis unit 30 to test the pre-diluted sample tube to be tested according to the test items.

[0052] In another embodiment, the information processing unit 40 can obtain the configuration information of this injection through a visual interface, and the configuration information stores the detection items specified by the user when setting the injection, so as to control the first analysis unit 20 and / or the second analysis unit 30 to detect the pre-diluted sample tube to be detected according to the detection items in the configuration information; or, the information processing unit 40 can also obtain the detection items when the previous sample to be tested was detected, so as to control the first analysis unit 20 and / or the second analysis unit 30 to detect the pre-diluted sample tube to be detected. It can be understood that a variety of injection options can be set in the injection setting, so that the information processing unit 40 can obtain the detection items of the sample to be tested according to any of the above methods according to the selected options, and the method for obtaining the detection items is not specifically limited here.

[0053] In the embodiment of the present application, the sample analysis system obtains the detection items of the sample tube to be diluted through the information processing unit 40, and instructs the first analysis unit 20 and / or the second analysis unit 30 to detect the pre-diluted sample tube to be detected according to the detection items. Since the first analysis unit 20 automatically pre-dilutes the sample tube to be diluted, the information processing unit 40 can directly control the first analysis unit 20 and / or the second analysis unit 30 to detect the pre-diluted sample tube to be detected, thereby realizing automatic sampling, pre-dilution, detection and other fully automatic tests of the sample analysis system, without the need for manual dilution matching, so that the sample analysis system can be suitable for high-speed detection scenarios with large sample volumes.

[0054] Optionally, the information processing unit 40 is used to bind the dilution ratio of the pre-diluted sample tube to be tested with the sample information of the pre-diluted sample tube to be tested in response to the sample tube to be diluted being marked as the pre-diluted sample tube to be tested, the first analysis unit 20 and / or the second analysis unit 30 are used to test the pre-diluted sample tube to be tested and obtain test data, and the information processing unit 40 is also used to generate a test result of the sample to be diluted based on the dilution ratio and the test data.

[0055] Specifically, since the detection data obtained from trace blood samples at different dilution ratios are suitable for different detection scenarios, when the sample tube to be diluted is marked as a pre-diluted sample tube to be tested, the information processing unit 40 is used to bind the dilution ratio of the pre-diluted sample tube to be tested with its sample information, so that the detection data of the pre-diluted sample tube to be tested is bound to the dilution ratio. The analysis unit and / or the central processing unit can generate a detection result or a detection report for the sample to be diluted based on the dilution ratio and detection data of the sample to be tested, which is convenient for the user to check the detection result and improves the user's experience.

[0056] Optionally, the sample injection unit 10 further includes a transfer mechanism (not shown), and the information processing unit 40 is used to obtain sample volume information from the second operation instruction in response to receiving the second operation instruction, so as to generate a transfer drive signal according to the sample volume information. The transfer mechanism is used to receive the transfer drive signal to transfer the first volume of the micro blood sample in the sampling tube to the sample tube to be diluted.

[0057] Specifically, the transfer mechanism is used to obtain a sampling tube storing a trace blood sample and transfer the trace blood sample in the sampling tube to the sample tube to be diluted. The second operation instruction of this embodiment is obtained by the user performing a corresponding operation in the visual interface of the above embodiment. In this embodiment, the user places the sampling tube that needs to be automatically tested in the injection area of ​​the injection unit 10, and performs injection settings through the visual interface to generate a second operation instruction; the information processing unit 40 is used to obtain sample volume information from the second operation instruction, and generate a transfer drive signal according to the sample volume information. The transfer drive signal is used to drive the transfer mechanism to transfer the trace blood sample in the sampling tube to the sample tube to be diluted according to the preset first capacity, so that the first analysis unit 20 can pre-dilute the sample to be diluted in the sample tube to be diluted according to the dilution ratio in the second operation instruction, so as to achieve accurate dilution of the sample to be diluted.

[0058] Furthermore, the transfer mechanism may also include a motion mechanism and a pipette needle, the motion mechanism is used to move the sampling tube and the sample tube to be diluted so that the sampling tube and the sample tube to be diluted are respectively located at the sample aspiration position of the pipette needle, and the pipette needle is used to absorb a first volume of trace blood sample to transfer the trace blood sample to the sample tube to be diluted.

[0059] In the embodiment of the present application, the sample analysis system realizes the quantitative transfer of trace blood samples through the transfer mechanism, reduces the workload of users, reduces labor costs, and improves the pre-dilution efficiency of trace blood samples.

[0060] See also Figure 3 , Figure 3 FIG. 1 is a flow chart of an embodiment of the sample analysis method provided by the present application. Figure 3 As shown, an embodiment of the present application provides a sample analysis method, which is applied to a sample analysis system in any of the above embodiments, and the sample analysis method includes the following steps:

[0061] Step S11: the information processing unit 40 controls the sample injection unit 10 to identify the sample tube in response to the received operation instruction from the user to obtain the type of the sample tube, wherein the operation instruction carries the ratio information of the sample tube to be diluted.

[0062] Specifically, the user can perform pre-dilution settings through a visual interface connected to the sample analysis system to generate an operation instruction and start the pre-dilution process of the sample analysis system. In response to the received operation instruction, the information processing unit 40 controls the sample injection unit 10 to identify the sample tube to obtain the type of the sample tube. The type of the sample tube in this embodiment can include a sample tube to be diluted and a normal sample tube (i.e., a sample tube that is not pre-diluted).

[0063] Step S12: In response to the sample tube being a sample tube to be diluted, the information processing unit 40 controls the sample injection unit 10 to move the sample tube to be diluted to the first analysis unit 20, so that the first analysis unit 20 pre-dilutes the sample to be diluted in the sample tube to be diluted according to the ratio information and prepares the sample to be tested.

[0064] The operation instruction carries the ratio information of the sample tube to be diluted. In response to the type of the sample tube being the sample tube to be diluted, the information processing unit 40 controls the sample injection unit 10 to move the sample tube to be diluted to the first analysis unit 20 and adjusts the working mode of the first analysis unit 20 to the pre-dilution mode. In the pre-dilution mode, the information processing unit 40 controls the first analysis unit 20 to perform a pre-dilution operation on the sample to be diluted of the sample tube to be diluted according to the ratio information, so as to prepare the sample to be diluted into the sample to be tested, so that the first analysis unit 20 and / or the second analysis unit perform sample analysis on the sample to be tested.

[0065] The sample tube to be diluted may be a sample tube with a specific shape or a specific mark, and the shape or mark of the sample tube to be diluted is identified by the injection unit 10 to determine whether the sample tube is a sample tube to be diluted; or, the sample tube to be diluted may be a sample tube with the same shape and specification as a normal sample tube, and the mark of the sample rack carrying the sample tube is identified by the injection unit 10 to determine whether the sample rack is a pre-dilution sample rack, and the sample tube on the pre-dilution sample rack is marked as a sample tube to be diluted.

[0066] Step S13: the information processing unit 40 instructs the first analysis unit 20 and / or the second analysis unit 30 to detect the sample to be tested according to the detection items corresponding to the sample to be tested, so as to obtain the detection result of the sample to be tested, wherein the first analysis unit 20 and the second analysis unit 30 have different working modes.

[0067] According to the detection items of the sample tube to be diluted, the first analysis unit 20 and / or the second analysis unit 30 are controlled to detect the sample to be tested to obtain the detection result of the sample to be tested. It can be understood that the working mode may include a detection mode and a pre-dilution mode, and the first analysis unit 20 includes at least a pre-dilution mode. When both the first analysis unit 20 and the second analysis unit 30 support the detection mode, in order to improve the detection applicability of the sample analysis system, the detection modes of the first analysis unit 20 and the second analysis unit 30 can be different, so that the sample analysis system can be applicable to a variety of detection scenarios.

[0068] In the embodiment of the present application, the information processing unit 40 controls the first analysis unit 20 to pre-dilute the sample to be diluted in the sample tube to be diluted according to the ratio information to obtain the sample to be tested. The information processing unit 40 also instructs the first analysis unit 20 and / or the second analysis unit 30 to test the pre-diluted sample to be tested according to the test items corresponding to the sample to be tested. The sample analysis method can support the sample analysis system to perform fully automatic testing of the sample to be diluted without manual dilution ratio, so that the sample analysis system can be applied to high-speed detection scenarios with large sample volumes, improve the analysis efficiency of the sample to be diluted, and reduce labor costs.

[0069] Optionally, see Figure 4 , Figure 4 FIG. 1 is a flow chart of another embodiment of the sample analysis method provided by the present application. Figure 4 As shown, step S12 also includes the following steps:

[0070] Step S21: the information processing unit 40 controls the first analysis unit 20 to add the second volume of diluent to the sample tube to be diluted, so as to pre-dilute the sample to be diluted according to a preset dilution ratio.

[0071] In response to the user's operation instruction, the information processing unit 40 obtains the dilution ratio and sample volume information of the sample tube to be diluted from the operation instruction, calculates the volume of the diluent required to be added to the sample to be diluted according to the dilution ratio and sample volume information, and controls the first analysis unit 20 to add the second volume of diluent to the sample tube to be diluted. For example, the operation instruction indicates that a 40 μL micro-blood sample is stored in the sample tube to be diluted, and the sample tube to be diluted needs to be diluted at a dilution ratio of 1:30. At this time, according to the calculation, it can be obtained that the second volume of the diluent is 1.2 ml.

[0072] Step S22: the information processing unit 40 binds the dilution ratio of the sample tube to be diluted with the sample information of the sample tube to be diluted, and marks the diluted sample tube to be diluted as a pre-diluted sample tube to be tested.

[0073] After the pre-dilution operation of the sample to be diluted is completed, the information processing unit 40 binds the dilution ratio of the sample tube to be diluted with the sample information of the sample tube to be diluted, so that the detection data of the sample to be tested is bound to the dilution ratio, which is convenient for the user to check the detection data according to the dilution ratio, and mark the diluted sample tube to be diluted as the pre-dilution sample tube to be tested.

[0074] Step S23: the information processing unit 40 controls the first analysis unit 20 to mix the pre-diluted sample tube to be tested, and obtains the mixed sample to be tested.

[0075] In response to the diluent having been added to the pre-diluted sample tube to be tested, the information processing unit 40 controls the first analysis unit 20 to perform a mixing operation on the pre-diluted sample tube to be tested, so as to make the diluted sample and the diluent in the pre-diluted sample tube to be tested uniform and obtain a mixed sample to be tested. The blood cells in the mixed sample to be tested are evenly distributed, which is beneficial to the on-machine testing of the sample to be tested.

[0076] In a possible implementation, the information processing unit 40 obtains the test items corresponding to the sample to be tested, and in response to the test items of the sample to be tested needing to be completed on the first analysis unit 20, executes step S23 to instruct the first analysis unit 20 to directly count and detect the mixed sample to be tested and obtain the test result. Alternatively, the information processing unit 40 executes steps S21-S22, and in response to the sample tube to be diluted being marked as the pre-dilution sample tube to be tested, further executes step S13.

[0077] Among them, the sample tube to be diluted is a state in which the information processing unit 40 marks the processed sample tube as needing to be pre-dilution operated, and the pre-diluted sample tube to be tested is a state in which the information processing unit 40 marks the sample tube as having performed the pre-dilution operation and waiting for testing. The information processing unit 40 marks the status of sample tubes in different test processes, so that the sample analysis system can perform corresponding operations on sample tubes with different marks.

[0078] In an embodiment of the present application, when a preset volume of diluent has been added to the sample tube to be diluted, the diluted sample tube to be diluted is marked as the pre-diluted sample tube to be tested, and the first analysis unit 20 is controlled to perform a mixing operation on the pre-diluted sample tube to be tested, so that the diluted sample to be tested in the pre-diluted sample tube to be tested reacts with the diluent and obtains the reacted sample to be tested, thereby realizing fully automatic testing such as automatic sampling, pre-dilution, and detection of the sample analysis system, without the need for manual dilution ratio, making the pre-dilution operation more accurate, improving the pre-dilution efficiency, and reducing labor costs.

[0079] Optionally, after all test items of the sample tube are tested, the information processing unit 40 controls the sample analysis system to withdraw the pre-diluted sample tube to be tested from the first analysis unit 20 or the second analysis unit 30, and moves the sample tube that has completed the test to the unloading area for unloading through the conveying mechanism 110, so as to realize automatic testing of trace blood samples.
