The phrase appears at various places in the specification does not necessarily refer to the same embodiment, nor is it necessarily mutually exclusive or alternative embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0023] Please refer to Figure 1 shown, Figure 1 is a structural schematic diagram of a first embodiment of a blood analyzer of the present application. The blood analyzer 10 of the present embodiment at least includes a sampling module 11, a routine blood test module 12 and a specific protein detection module 13.

[0024] The sampling module 11 is used to collect a blood sample; when the blood analyzer 10 performs routine blood test through the routine blood test module 12 and specific protein detection through the specific protein detection module 13, the blood sample is a whole blood sample.

[0025] Among them, the routine blood test includes WBC (white blood cell), HGB (hemoglobin), RBC (red blood cell), DIFF (differential, white blood cell five classification) or RET (reticulocyte count).

[0026] The sampling module 11 is used to add the collected blood sample to the blood routine testing module 12. The blood routine testing module 12 is used to dilute the blood sample; that is, the blood routine testing module 12 serves as a dilution pool for the specific protein detection module 13 to dilute the blood sample. For example, the blood sample and the diluent in the blood routine testing module 12 are mixed to allow the blood routine testing module 12 to dilute the blood sample.

[0027] The sampling module 11 is used to draw diluted blood samples from the blood routine test module 12 and add the diluted blood samples to the specific protein detection module 13. The specific protein detection module 13 is used to perform specific protein detection on the diluted blood samples.

[0028] Among them, the specific proteins include one of SAA (serum amyloid A protein), CRP (C-reactive protein), TRF (transferrin), Hs-CRP (high-sensitivity C-reactive protein), PCT (procalcitonin), and D-Dimer. For example, the specific protein detection module 13 performs CRP detection on diluted blood samples.

[0029] In this embodiment, the sampling module 11 adds the collected blood sample to the blood routine detection module 12, which dilutes the blood sample. The sampling module 11 then adds the diluted blood sample to the specific protein detection module 13, which performs specific protein detection on the diluted blood sample. In other words, the blood routine detection module 12 acts as a dilution pool for the specific protein detection module 13 to dilute the blood sample, preventing excessively high concentrations of specific proteins and improving the accuracy of the blood analyzer 10. Furthermore, the blood analyzer 10 performs both blood routine and specific protein detection, improving its detection efficiency and avoiding the inconvenience caused to patients by multiple samplings.

[0030] Please see Figure 2 As shown, Figure 2 This is a schematic diagram of the structure of a second embodiment of the blood analyzer of this application. The blood analyzer 10 includes a control module 14 connected to a sampling module 11, a routine blood count (RBC) testing module 12, and a specific protein detection module 13, respectively. The RBC testing module 12 includes a first RBC testing pool 121, and the specific protein detection module 13 includes a specific protein detection pool 131. In other embodiments, the RBC testing module 12 includes multiple RBC testing pools, and the specific protein detection module 13 includes multiple specific protein detection pools 131.

[0031] The first blood routine test pool 121 is configured to dilute the blood sample to obtain a diluted blood sample, and further configured to perform blood routine test on the diluted blood sample. The specific protein test pool 131 is configured to perform specific protein test on the diluted blood sample, for example, the specific protein test pool 131 is configured to perform CRP test on the diluted blood sample.

[0032] The control module 14 is configured to control the sampling module 11 to draw the blood sample from the blood sample test tube 15, i.e., the control module 14 controls the sampling module 11 to draw the blood sample from the blood sample test tube 15 at the blood sampling position. For example, the blood analyzer 10 can include a test tube rack, and the plurality of blood sample test tubes 15 are arranged on the test tube rack. The test tube rack is configured to sequentially move the plurality of blood sample test tubes 15 to the blood sampling position, and the blood sampling position is the position where the sampling module 11 draws the blood sample.

[0033] Optionally, the blood analyzer 10 includes an optical coupling positioning assembly arranged at the blood sampling position and configured to determine whether the blood sample test tube 15 is located at the blood sampling position. For example, the control module 14 is configured to control the test tube rack to sequentially move the plurality of blood sample test tubes 15, and determine that the blood sample test tube 15 is located at the blood sampling position by the optical coupling positioning assembly, and then stop the test tube rack from sequentially moving the plurality of blood sample test tubes 15.

[0034] The control module 14 is configured to control the sampling module 11 to add the blood sample to the first blood routine test pool 121, so as to mix the blood sample and the diluent in the first blood routine test pool 121 to obtain a diluted blood sample. The first blood routine test pool 121 can store a certain amount of diluent. After the sampling module 11 adds the blood sample to the first blood routine test pool 121, the control module 14 can control the sampling module 11 to draw and push the blood sample and the diluent, so as to mix the blood sample and the diluent in the first blood routine test pool 121. In other embodiments, the bottom of the blood routine test pool (e.g., the first blood routine test pool 121) is provided with a mixing device, for example, a mixing device such as a pump or a syringe, to mix the liquid in the blood routine test pool.

[0035] The control module 14 is configured to control the sampling module 11 to perform cleaning and draw the diluted blood sample from the first blood routine test pool 121. In order to avoid contamination of the diluted blood sample in the first blood routine test pool 121, the sampling module 11 is cleaned. The control module 14 controls the sampling module 11 to draw the diluted blood sample from the first blood routine test pool 121.

[0036] The control module 14 is configured to control the sampling module 11 to add the diluted blood sample into the specific protein detection pool 131, so as to mix the diluted blood sample with the hemolytic agent and the latex reagent in the specific protein detection pool 131, and then perform specific protein detection on the diluted blood sample. For example, the blood analyzer 10 can comprise a reagent module, and the control module 14 controls the reagent module to add the hemolytic agent and the latex reagent (also referred to as antibody reagent) into the specific protein detection pool 131, so as to mix the diluted blood sample, the hemolytic agent and the latex reagent, and the control module 14 performs specific protein detection on the diluted blood sample through the specific protein detection pool 131.

[0037] In some embodiments, the control module 14 can control the sampling module 11 to aspirate and eject the diluted blood sample, the hemolytic agent and the latex reagent, so as to mix the diluted blood sample, the hemolytic agent and the latex reagent. In other embodiments, the specific protein detection pool 131 is provided with a mixing device at the bottom, such as a pumping device or a syringe, to mix the liquid in the specific protein detection pool 131.

[0038] Optionally, the control module 14 determines whether the specific protein detection pool 131 performs specific protein detection on the diluted blood sample abnormally. If so, the control module 14 determines that the specific protein detection pool 131 performs specific protein detection on the diluted blood sample abnormally, and then controls the sampling module 11 to re-aspirate the diluted blood sample from the first blood routine detection pool 121 and add the diluted blood sample into the specific protein detection pool 131, so as to re-perform specific protein detection on the diluted blood sample by the specific protein detection pool 131.

[0039] Optionally, the first blood routine detection pool 121 is arranged between the specific protein detection pool 131 and the blood sampling position, so that the sampling module 11 moves the shortest distance during the detection of the blood analyzer 10, thereby shortening the detection time of the blood analyzer 10 and improving the detection efficiency of the blood analyzer 10.

[0040] Optionally, before the sampling module 11 aspirates the blood sample from the blood sample tube 15, the control module 14 further controls the sampling module 11 to aspirate the blood sample from the blood sample tube 15 and add the blood sample into the specific protein detection pool 131, so as to perform specific protein detection on the blood sample and obtain a first detection result. The control module 14 determines whether the blood sample is a high-value sample based on the first detection result. If so, the control module 14 determines that the blood sample is a high-value sample, and then controls the sampling module 11 to aspirate the blood sample from the blood sample tube 15 to dilute the blood sample through the first blood routine detection pool 121. Therefore, the sampling module 11 realizes secondary sampling, and the high-value sample is diluted, thereby improving the accuracy of the detection of the blood analyzer 10.

[0041] Optionally, when the sampling module 11 completes the suction of the blood sample from the blood sample tube 15, the control module 14 controls the tube rack to continue the movement of the blood sample tube 15. When the control module 14 determines that the blood sample is a high-value sample, the control module 14 controls the tube rack to return the sampled blood sample tube 15 to the blood collection position. When the control module 14 determines that the blood sample is not a high-value sample, the blood sample tube 15 continues to move, which can improve the detection efficiency of the blood analyzer 10.

[0042] Please refer to Figure 3 as shown, Figure 3 is a structural schematic diagram of a third embodiment of the blood analyzer of the present application. The blood analyzer 10 of the present embodiment comprises a first container C1 for storing diluent, and the sampling module 11 comprises a driving device 111, a syringe 112, a controllable valve 113, and a sampling needle 114.

[0043] The driving device 111 is connected to the control module 14 and the syringe 112, respectively, and is used to drive the syringe 112. The common end of the controllable valve 113 is connected to the syringe 112 through a pipeline, the first branch end of the controllable valve 113 is connected to the first container C1 through a pipeline, and the second branch end of the controllable valve 113 is connected to the sampling needle 114 through a pipeline. In other embodiments, the sampling module 11 can be provided with a quantitative pump to realize the functions of the driving device 111 and the syringe 112.

[0044] The control module 14 controls the common end and the first branch end of the controllable valve 113 to be in communication, so that the syringe 112 sequentially communicates the controllable valve 113 and the first container C1 through the pipeline; the control module 14 controls the syringe 112 to suck the diluent from the first container C1 through the driving device 111. The control module 14 controls the common end and the second branch end of the controllable valve 113 to be in communication, so that the syringe 112 sequentially communicates the controllable valve 113 and the sampling needle 114 through the pipeline, and at this time the syringe 112 sucks or pushes out the blood sample and the diluted blood sample through the sampling needle 114.

[0045] The controllable valve 113 can be a three-way valve, which comprises a common end and two branch ends. The three-way valve realizes the selection of the three ports by means of on-off electricity, for example, when powered on, the common end and the first branch end are selected, and when powered off, the common end and the second branch end are selected. Those skilled in the art should know that if the connection mode of the first branch end and the second branch end is exchanged and the selection of the three-way valve is controlled in the opposite way, the same effect as the above-mentioned embodiment can be achieved, which should also be within the scope of the present embodiment.

[0046] Optionally, the sampling module 11 comprises a cleaning swab 115, which is arranged on the sampling needle 114 and is used to clean the outer wall and the inner wall of the sampling needle 114.

[0047] In addition, the sampling module 11 comprises a moving assembly, and the sampling needle 114 is arranged on the moving assembly. The moving assembly is configured to drive the sampling needle 114 to move in the horizontal direction or the vertical direction, so as to drive the sampling needle 114 to move.

[0048] The first blood routine detection pool 121 can comprise a WBC detection pool, an RBC detection pool, a DIFF detection pool or a RET detection pool. When the first blood routine detection pool 121 is the RBC detection pool, the control module 14 controls the sampling module 11 to add a diluent to the first blood routine detection pool 121, so as to perform RBC detection through the first blood routine detection pool 121 when performing specific protein detection on the diluted blood sample.

For example, the control module 14 controls the moving assembly to move the sampling needle 114 to the blood sampling position, where the blood sampling position is the initial position of the sampling needle 114.

[0051] The control module 14 controls the sampling needle 114 to move to the first blood routine detection pool 121, and adds the blood sample to the first blood routine detection pool 121.

Meanwhile, the control module 14 controls the sampling needle 114 to move to the first blood routine detection pool 121, so as to add the diluent to the first blood routine detection pool 121. Then, the diluted blood sample is diluted and mixed again, so as to detect the RBC signal and perform RBC detection.

[0055] The control module 14 controls the sampling needle 114 to move, and the outer wall and the inner wall of the sampling needle 114 are cleaned by the cleaning swab 115.

[0087] It is determined whether the blood sample is a high-value sample based on the first detection result. The high-value sample refers to a blood sample with a specific protein concentration greater than a certain threshold. If yes, it is determined that the blood sample is a high-value sample, and the step S603 is entered. If no, the next blood sample is detected by the blood analyzer 10.

[0088] S603: Collect a blood sample, and add the blood sample into the blood routine test module 12.

[0089] S604: Dilute the blood sample by the blood routine test module 12.

[0091] Steps S603-S605 are the same as steps S501-S503 in the detection method of the first embodiment, and will not be described again here.

[0092] In the first blood routine detection pool 121 is an RBC detection pool, the detection method further comprises: when detecting the specific protein of the diluted blood sample, the sampling module 11 is controlled to add a diluent to the first blood routine detection pool 121, so as to perform RBC detection through the first blood routine detection pool 121.
