[0027] To make the above objects, features, and advantages of the present application more obvious and understandable, the following will describe the detailed implementation manners of the present application in conjunction with the drawings. It can be understood that the specific embodiments described herein are only used to explain the present application, rather than limiting the present application. Additionally, it should be noted that for the convenience of description, only the parts related to the present application are shown in the drawings, rather than all the structures. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0028] The terms "first", "second", etc. in the present application are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products, or devices.

[0029] Referring to "embodiment" in this context means that the specific features, structures, or characteristics described in conjunction with the embodiment can be included in at least one embodiment of the present application. The occurrence of this phrase in various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0030] Before sample measurement, the appearance of the sample needs to be strictly inspected for any damage or leakage, and whether the color of the sample is qualified and whether the color of the plasma is abnormal. After observing the sample, the sample is then subjected to machine detection. Before measuring a whole blood sample, the sample analyzer of the present application first captures a photo of the whole blood and saves the photo of the whole blood. When clinical doubts arise or the patient's disease requires re-observing the sample appearance, the saved original whole blood picture can be retrieved, thus saving the steps of re-centrifuging the sample or re-drawing the sample.

[0031] The present application first provides a sample analyzer. Please refer to Figure 1 as shown Figure 1 which is a schematic framework diagram of a sample analyzer provided by the present application. Specifically, the sample analyzer 10 includes an image acquisition unit 11, a storage unit 12, a sample mixing unit 13, an analysis unit 14, and a control unit 15.

[0032] Specifically, the image acquisition unit 11 is used to acquire an image of the test tube 20, where the test tube 20 contains an untreated original sample. The original sample can be a whole blood sample, a urine sample, a sweat sample, etc.

[0033] The image acquisition unit 11 can acquire an image of the test tube 20 before the original sample is mixed to obtain an image of the original sample. The image acquisition unit 11 can include a camera, a lens, a sensor, etc. The image of the test tube 20 acquired by the image acquisition unit 11 can be a color image, enabling a doctor to more accurately observe the state of the original sample. In other embodiments, the image of the test tube 20 acquired by the image acquisition unit 11 can also be a black-and-white image, a gray image, etc., which is not limited herein.

[0034] The storage unit 12 is used to store the image of the test tube 20 acquired by the image acquisition unit 11, and the storage unit 12 can also be used to store the feature information of the image of the test tube 20.

[0035] The sample mixing unit 13 is used to mix the original sample in the test tube 20. Specifically, after the image acquisition unit 11 acquires the image of the test tube 20, the sample mixing unit 13 then performs a mixing operation on the original sample in the test tube 20.

[0036] The analysis unit 14 is used to analyze and detect the mixed original sample to obtain the test result of the sample.

[0037] Further, as Figure 1As shown, the sample analyzer 10 may further include a sampling unit 16, which can be used for automatic sampling. The image acquisition unit 11 can be set at an image acquisition position relative to the sampling unit 16. The sample mixing unit 13 is set at a mixing position relative to the sampling unit 16, and the analysis unit 14 is set at an analysis position relative to the sampling unit 16. The sampling unit 16 can move the test tube 20 to the image acquisition position so that the image acquisition unit 11 can acquire an image of the test tube 20. The sampling unit 16 can also move the test tube 20 after the image acquisition is completed to the mixing position so that the sample mixing unit 13 can perform a mixing operation on the original sample in the test tube 20. The sampling unit 16 can also move the test tube 20 after the mixing is completed to the analysis position so that the analysis unit 14 can detect the sample in the test tube 20 at the analysis position.

[0038] The control unit 15 is connected to the image acquisition unit 11, the storage unit 12, the sample mixing unit 13, the analysis unit 14, and the sampling unit 16.

[0039] Based on the sample analyzer 10 of any of the above embodiments, the present application also provides a control method for a sample analyzer. Please refer to Figure 2 As shown, Figure 2 is a schematic flowchart of an embodiment of a control method for a sample analyzer provided by the present application. Specifically, the control method includes:

[0040] S11: Control the image acquisition unit to acquire an image of a test tube containing an untreated original sample, and store the image of the test tube in the storage unit.

[0041] The image acquisition unit 11 can be used to acquire an image of the test tube 20. Preferably, the image acquired by the image acquisition unit 11 is a color image.

[0042] When the sample analyzer includes the sampling unit 16, the control unit 15 can control the sampling unit 16 to move the test tube 20 to the image acquisition position, and the image acquisition unit 11 automatically acquires an image of the test tube 20 at the image acquisition position to obtain an image of the test tube 20, thereby obtaining an image of the original sample.

[0043] In other embodiments, the test tube 20 can also be held by hand to the image acquisition position corresponding to the image acquisition unit 11, and the image acquisition unit 11 is started to take a picture of the test tube 20.

[0044] After the image acquisition unit 11 obtains the image of the test tube 20, the control unit 15 saves the acquired image of the test tube 20 to the storage unit 12 for the doctor to view later.

[0045] S12: Control the sample mixing unit to perform a mixing operation on the original sample in the test tube after the image acquisition is completed.

[0046] After the image of the test tube 20 is acquired, the test tube 20 is made to go through the detection process. Specifically, the control unit 15 can control the sample mixing unit 13 to perform a mixing operation on the original sample in the test tube 20 to mix the original sample in the test tube 20.

[0047] When the sample analyzer 10 includes the sample injection unit 16, after the image acquisition unit 11 finishes acquiring the image of the test tube 20, the control unit 15 can control the test tube 20 to move to the mixing position so that the sample mixing unit 13 performs a mixing operation on the original sample in the test tube 20 at the mixing position.

[0048] In other embodiments, the test tube 20 after the image acquisition is completed can also be manually taken to the corresponding mixing position of the sample mixing unit 13 so that the sample mixing unit 13 performs a mixing operation on the original sample.

[0049] S13: Control the analysis unit to perform detection and analysis on the mixed original sample.

[0050] After the sample mixing unit 13 finishes mixing the sample, the control unit 15 controls the analysis unit 14 to perform detection and analysis on the mixed sample to obtain the detection result of the sample.

[0051] When the sample analyzer 10 includes the sample injection unit 16, the sample injection unit 16 moves the test tube 20 after the mixing is completed to the analysis position, and the control unit 15 controls the analysis unit 141 to perform detection and analysis on the sample in the test tube 20.

[0052] In other embodiments, the test tube 20 after the mixing is completed can also be manually taken to the corresponding analysis position of the analysis unit 14 so that the analysis unit 14 performs detection and analysis on the sample.

[0053] Before the sample analyzer 10 in the above embodiments performs detection on the original sample, the image acquisition unit 11 acquires the image of the original sample, saves the image of the original sample to the storage unit 12, and then performs subsequent mixing and detection processes on the original sample. In this way, the doctor can call out the image of the original sample as needed, so that the doctor can timely understand the state of the original sample, provide a reference for the doctor to make a disease diagnosis, and moreover, it can save the links of re-centrifuging the sample or re-drawing the sample.

[0054] Further, as Figure 1 shown, the sample analyzer 10 may further include an image recognition unit 17, and the image recognition unit 17 is used to recognize the image of the test tube 20 acquired by the image acquisition unit 11.

[0055] Specifically, the image recognition unit 17 can identify feature information such as the color or morphology of the sample through corresponding recognition algorithms. For example, if the color of the plasma is different from its normal state, there may be phenomena such as coagulation, lipemia, floccules, and hemolysis. Among them, floccules refer to: floating in a sticky filamentous form in the plasma layer, sometimes with a small amount of red blood cells adhering, and if shaken repeatedly, it is likely to sink into the red blood cell layer and cause red blood cells to adhere and form clots. Clots refer to: clots appearing on the test tube, which may be due to uneven mixing or abnormal anticoagulation. Hemolysis refers to: when the blood stands and precipitates, the plasma part is transparent and uniformly red. Lipemia refers to: the plasma layer is opaque yellow or white and milky.

[0056] After the image recognition unit 17 performs image recognition on the test tube 20, it outputs feature information such as the color or state of the original sample, such as feature information like "light yellow", "yellow", "dark yellow", "milky white", "turbid", "red", "floccules", "clots", etc.

[0057] By automatically identifying specific abnormal phenomena of the original sample through the image recognition unit 17, the workload of the staff can be reduced, and the accuracy of image recognition by the automatic recognition technology is higher, which can supplement more detailed feature information of the original sample.

[0058] Furthermore, as Figure 1 shown, the sample analyzer 10 may further include an image cutting unit 18. The image cutting unit 18 is used to cut the image of the test tube 20 to intercept necessary test tube information and retain the image of the test tube part (as shown in (c) in Figure 4 ), reducing the size of the image and effectively saving the space of the storage unit 12.

[0059] Optionally, as Figure 1 shown, the sample analyzer 10 may further include: an auxiliary light source unit 19 and a test tube angle adjustment unit 21.

[0060] Affected by environmental light and light inside the machine, in some cases, the light of the image of the test tube 20 collected by the image acquisition unit 11 may be insufficient, resulting in an unclear image of the test tube 20 collected, thus affecting the accuracy of the saved original sample. By setting the auxiliary light source unit 19, the brightness of the environment can be adjusted to make the image of the test tube 20 have a better effect. Specifically, the image recognition unit 17 can recognize the initial image collected by the image acquisition unit 11. When it is confirmed that the light of the image obtained by the image acquisition unit 11 is insufficient (as shown in the left figure in Figure 5 ), the auxiliary light source unit 19 is activated to adjust the environmental brightness, and then the control unit 15 controls the image acquisition unit 11 to re-collect the image of the test tube 20 (as shown in Figure 5as shown in the right figure in). The clarity of the image of the test tube 20 collected can be improved by the auxiliary light source unit 19.

[0061] Furthermore, the control unit 15 can also save the power value of the auxiliary light source unit 19, so that when the image acquisition unit 11 performs the next image acquisition, the auxiliary light source unit 19 automatically adjusts to this power value, and the ambient brightness automatically reaches the optimal value.

[0062] Furthermore, the direction of the test tube 20 during placement is random. When the image acquisition unit 11 acquires the image of the test tube 20, the original sample in the image of the photographed test tube 20 may be blocked by the label attached to the test tube 20. The image recognition unit 17 can also recognize the image of the test tube 20 to confirm whether the original sample in the test tube 20 is blocked. When it is confirmed that the sample in the test tube 20 is blocked (such as Figure 4 as shown in (a) in), the test tube angle adjustment unit 21 is started to adjust the angle of the test tube 20, and then the control unit 15 controls the image acquisition unit 11 to re-acquire the image of the test tube 20 (such as Figure 4 as shown in (b) in), to replace the historical image of the test tube 20. By this means, the accuracy of the image of the test tube 20 can be improved.

[0063] Optionally, as Figure 6 shown, the image acquisition unit 11 can also acquire images of multiple test tubes 20 each time. For example, the image acquisition unit 11 can simultaneously photograph the test tubes 20 on a whole row of test tube racks, and then the image recognition unit 17 recognizes the images of multiple test tubes 20 to obtain multiple different test tube parts; then the image cutting unit 18 cuts the multiple test tubes 20 in the image (such as Figure 7 shown), to segment out the images of each test tube 20, and then associate the sample numbers with the images of each test tube 20 and save them in the storage unit 12. By this means, the number of times the image acquisition unit 11 acquires images can be reduced, and the detection efficiency of the sample analyzer 10 can be improved.

[0064] Optionally, as Figure 1 shown, the image acquisition unit 11 can also include an image display unit 22. The control unit 15 is connected to the image display unit 22, and the image display unit 22 can be used to display the saved images of the test tube 20 for the doctor to view the images.

[0065] For example, as Figure 3As shown, in some specific embodiments, the control method of the sample analyzer 10 may be as follows: The sample injection unit 16 moves the test tube 20 to the image sampling position, and the image acquisition unit 11 acquires an image of the test tube 20 at the image sampling position. The image of the test tube 20 may be a color image. Then, the image recognition unit 17 recognizes the acquired image of the test tube 20 to determine whether the background of the image is relatively dark or the light of the image is insufficient. When it is confirmed that the background of the image is relatively dark, the power of the auxiliary light source unit 19 is adjusted to adjust the brightness of the ambient light. Then, the image acquisition unit 11 is controlled to re-acquire the image of the test tube 20 to overwrite the historical image. When it is confirmed that there is no situation of dark background or insufficient light in the image, the power of the auxiliary light source unit 19 does not need to be adjusted. Then, the image recognition unit 17 recognizes whether the original sample in the test tube 20 is blocked. When it is confirmed that the sample in the test tube 20 is blocked by the label of the test tube 20, the test tube angle adjustment unit 21 is controlled to adjust the angle of the test tube 20. Then, the control unit 15 controls the image acquisition unit 11 to re-acquire the image of the test tube 20 to replace the historical image of the test tube 20. After obtaining a clearer image of the test tube 20, the image is cut by the image cutting unit 18 to retain the image of the test tube part. Then, the graphic image recognition unit 17 recognizes the characteristic information such as the color and shape of the original sample in the image. Then, the image of the test tube 20 and its characteristic information are stored in the storage unit 12. When the doctor needs to view the image of the test tube 20, the image display unit 22 can display the image of the test tube 20 and its characteristic information for the doctor to refer to and judge.

[0066] In some specific embodiments, such as Figure 8 for the original sample in, the sample analyzer 10 reports "HGB (Hemoglobin) interference", the sample RBC (Red Blood Cell) is low, and the plasma characteristic indicates "yellow". After the doctor views the image of the original sample ( Figure 8 ) and its corresponding characteristic information, it is found that the plasma color is yellowish, suspecting hemolytic jaundice. The original sample is sent for serum total bilirubin test in time. If the serum total bilirubin > 20 mg / dl, then timely intervention treatment is required. Therefore, it can provide reference for the doctor's disease diagnosis.

[0067] In some other embodiments, such as Figure 9 for the original sample in, the sample analyzer 10 reports "lipid particles", and the HGB of the sample is high. The doctor can directly input the sample number in the sample analyzer 10, and the image of the test tube 20 corresponding to the original sample is displayed on the image display unit 22 to see the plasma state of the sample before mixing. From Figure 9 it can be seen that the plasma presents milky white, which conforms to the characteristics of lipid samples. If necessary, the doctor will further measure the triglyceride content to identify the true concentration of lipid particles.

[0068] In some other embodiments, such as Figure 10 the original sample in, the sample analyzer 10 reports an "abnormal background or sampling" alarm. However, when the doctor questions the blood volume in the whole blood test tube, instead of looking up the patient code and finding the original sample from a large number of test tubes in the refrigerator, the sample number can be directly input into the sample analyzer 10, and the image of the test tube can be opened to see whether the amount of the original sample is sufficient.

[0069] Therefore, the sample analyzer 10 provided by the present application can store the image of the original sample in advance. When the test result of the sample is clinically questioned or the disease of the patient requires re-observing the appearance of the original sample, the image of the original sample can be conveniently retrieved, providing a reference for the doctor to diagnose the disease. Moreover, it can save the steps of re-centrifuging the sample or re-drawing the sample.

[0070] The above are only the embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present application.
