[0025] In the embodiment, the output device 106 of the sample detection device 100 can be a touch display screen, a liquid crystal display screen, or a liquid crystal display, a television, or a display device independent of the sample detection device 100, or a display screen of a mobile phone or a tablet computer.

[0026] For details, please refer to Figure 2 An embodiment of the sample analysis method includes the following steps.

[0027] 201. The sample detection device draws a sample, which includes a sample required by a preliminary check item and a sample required by a recheck item, wherein the recheck item is determined according to the preliminary check item.

[0028] The sample detection device determines a preliminary check item and a recheck item corresponding to the preliminary check item before detection. Then, the sampling needle in the sample detection device draws a sample, which includes a sample required by the preliminary check item and a sample required by the recheck item.

[0029] In this embodiment, the review item is used to verify whether the abnormal detection result of the primary item is correct, and the review item is determined according to the abnormal detection result of the primary item. In this embodiment, when the sample is a blood sample, the primary item can include red blood cell (RBC) detection, and the corresponding review item can include reticulocyte (RET) detection. Specifically, in the detection process of the blood sample, clinical judgment of anemia is mainly made by the detection result of RBC. If the RBC parameter is abnormal, the detection result of RET is added to provide further basis for clinical judgment. At the same time, the number of reaction pools for review in the sample detection equipment is limited, and the sample detection equipment can only select part of the review items corresponding to the primary items. In an exemplary scheme, the sample detection equipment can select the review items corresponding to the primary items whose review probability is greater than a preset threshold in the primary items or select the review items corresponding to the primary items whose importance level is higher. For example, in a detection including multiple primary items, if the preset threshold is 60%, and the detection result of item A in the primary items has a review probability greater than 60%, the review item is determined according to the detection result of the item A; or in a detection including multiple primary items, if the detection result of the primary item A is very important, the review item can be determined according to the detection result of the primary item A. In actual application, when the number of reaction pools corresponding to the review items is limited and less than the number of review items corresponding to the primary items, the sample required by the review items can be taken from the sample demand of the review items from large to small. For example, the sample detection equipment only uses 2 reaction pools as the reaction pools corresponding to the review items, but the reaction corresponding to the primary items has 4, and the review items determined according to the detection result of the primary items also have 4, and the required samples are 0.1 ml, 0.2 ml, 0.1 ml and 0.15 ml respectively; then the sample detection equipment injects 0.2 ml and 0.15 ml of sample into the reaction pools corresponding to the review items respectively, and the sample taken by the sampling needle needs to include the samples corresponding to the 4 primary items and the 0.35 ml sample.

[0030] It can be understood that the initial test item and the retest item can be input by the user through the input device, or the sample detection device can determine the retest item corresponding to the initial test item according to the mapping relationship table of the initial test item and the retest item after obtaining the initial test item input by the user. For example, the input device of the sample detection device can be a touch screen, and the touch screen can display an input box, and then the user inputs the initial test item and the retest item through the input box. Alternatively, the touch screen displays options of each test item, and the initial test item and the retest item are obtained by clicking the options on the touch screen. In this embodiment, the initial test item and the retest item can also be input in other ways, such as setting a button to input the initial test item and the retest item through the button.

[0031] 202. The sample detection device divides and injects the sample required by the initial test item into the corresponding first reaction pool and divides and injects the sample required by the retest item into the second reaction pool according to a preset ratio, wherein the first reaction pool is used to mix the sample with a reaction reagent required for initial test item detection to prepare an initial test mixture, and the second reaction pool is used to mix the sample with a diluent to form a diluted sample.

[0032] After the sampling needle of the sample detection device sucks the sample, the sample detection device divides and injects the sample according to a preset ratio. That is, the sample in the sampling needle is injected into the first reaction pool corresponding to the initial test item according to the sample required by the initial test item, and the sample in the sampling needle is injected into the second reaction pool corresponding to the retest item according to the sample required by the retest item. After the sample is divided and injected, the sample in the first reaction pool is mixed with the reaction reagent required for initial test item detection to prepare an initial test mixture, and the sample in the second reaction pool is mixed with a diluent to form a diluted sample.

[0033] In this embodiment, the first reaction pool is the reaction pool corresponding to the initial test item, and the second reaction pool is the reaction pool corresponding to the retest item. The number of the first reaction pool and the second reaction pool is at least one.

[0034] In this embodiment, when the sample is a blood sample, the initial test item includes RBC detection, and the retest item includes RET, the sample detection device can first divide and inject the blood sample required for RET detection into the second reaction pool according to the preset ratio when dividing and injecting the sample; and then divide and inject the blood sample required for RBC detection into the first reaction pool according to the preset ratio. That is, when dividing and injecting the blood sample, the sample for RET detection is injected first, and then the sample for RBC detection is injected. Since the platelet (PLT) parameter of reticulocyte detection is easy to adhere to the needle wall of the sampling needle, in order to reduce the adhesion, the blood sample close to the needle tip is allocated to the reticulocyte reaction pool as much as possible.

[0035] 203、the sample detection device detects the preliminary detection mixture in the first reaction pool to obtain a detection parameter.

[0036] the sample detection device detects the preliminary detection mixture in the first reaction pool according to a detection procedure to obtain a detection parameter.

[0037] It can be understood that in this embodiment, the detection parameter can be a final detection result of the preliminary detection item, or can be a real-time detection value of real-time change in the preliminary detection item. For example, in a blood sample detection process, the detection parameter can be a final detection result, which includes red blood cell count, white blood cell count, platelet count, etc. If the detection parameter is a real-time detection value, the real-time detection value can be the red blood cell count, white blood cell count, platelet count, etc. at the current time in the detection process.

[0038] 204、when the detection parameter meets the re-detection condition, the sample detection device mixes the diluted sample and a reaction reagent required for a re-detection item corresponding to the detection parameter to prepare a re-detection mixture.

[0039] In this embodiment, the detection parameter meeting the re-detection condition can be as follows: when the final detection result of the preliminary detection item exceeds a normal range, it is determined that the final detection result meets the re-detection condition, and the final detection result is the detection parameter; or, when a real-time detection value in the preliminary detection item test process exceeds the normal range, it is determined that the real-time detection value meets the re-detection condition, and the real-time detection value is the detection parameter. In an exemplary scheme, in a blood sample detection process, the detection parameter can be a final detection result, which includes red blood cell count, white blood cell count, platelet count, etc.; when the red blood cell count in the final detection result is displayed to exceed the normal range, the sample detection device determines that the red blood cell detection needs to be re-detected. If the detection parameter is a real-time detection value, the real-time detection value can be the red blood cell count, white blood cell count, platelet count, etc. at the current time in the detection process; if it is found that the red blood cell count has exceeded the normal range in the detection process, or the red blood cell count in the final detection result is predicted to exceed the normal range according to the red blood cell count at the current time, the sample detection device determines that the red blood cell detection needs to be re-detected.

[0040] When the sample detection device determines that re-detection is required, the sample detection device selects a reaction pool corresponding to the re-detection item from the second reaction pool, and mixes the diluted sample with a reaction reagent required for the re-detection item to prepare a re-detection mixture.

[0041] It can be understood that in the embodiment, the sample detection device can directly prepare the recheck mixed solution in the second reaction pool, or can suck the diluted sample from the second reaction pool to a detection reaction pool, and then prepare the recheck mixed solution in the detection reaction pool. The specific process is not limited here.

[0042] In the embodiment, if the detection parameters of the recheck item are all within the normal range, the sample detection device empties the diluted sample in the second reaction pool and cleans the second reaction pool.

[0043] 205. The sample detection device rechecks the recheck mixed solution to obtain a recheck result.

[0044] After the recheck mixed solution is prepared, the sample detection device detects the recheck mixed solution according to a normal detection process, so as to obtain a recheck result.

[0045] In the embodiment, after the recheck result is obtained, the sample detection result can comprehensively judge the recheck result and the detection parameters of the recheck item, so as to obtain a final detection result of the sample.

[0046] In an exemplary scheme of the embodiment, the first reaction pool and the second reaction pool of the sample detection device can be as shown in Figure 3 The sample detection device includes a sampling needle, a RET reaction pool, and a reaction pool 1 and a reaction pool 2. The RET reaction pool is used for RET recheck, the reaction pool 1 and the reaction pool 2 are used for regular detection, and the sampling needle is used for sucking a sample. The blood sample required for the RET detection and the blood sample required for the regular detection of the reaction pool 1 and the reaction pool 2. The specific operation process can be as shown in Figure 4As shown, after starting sample measurement, sample collection is performed. Specifically, sample collection is mainly performed by the sampling needle sucking blood samples required for the RET detection and blood samples required for routine detection of the reaction pool 1 and the reaction pool 2; then reaction pool blood distribution is performed, specifically, the sampling needle distributes the blood samples in the sampling needle according to the blood samples required for the detection items corresponding to each reaction pool (for example, the RET reaction pool injects the blood samples required for the RET detection, the reaction pool 1 injects the blood samples required for the detection items corresponding to the reaction pool 1, and the reaction pool 2 injects the blood samples required for the detection items corresponding to the reaction pool 2); then the reaction pool 1 and the reaction pool 2 normally perform routine detection, while the RET reaction pool is in a waiting state, at which time the sample in the RET reaction pool is mixed with a diluent to prepare a diluted sample; during the test of the reaction pool 1 and the reaction pool 2, the detection parameters of the reaction pool 1 and the reaction pool 2 are judged to determine whether the RET recheck needs to be started; if so, the detection of the reaction pool 1 and the reaction pool 2 ends, and the ready state is restored, at the same time, the reagents required for the RET detection are added to the diluted sample in the RET reaction pool to prepare a RET recheck mixed solution, then the RET recheck mixed solution is detected to obtain a recheck result, and finally the detection ends and the ready state is restored; if not, the detection of the reaction pool 1 and the reaction pool 2 ends, and the ready state is restored, while the RET reaction pool is emptied of the diluted sample and the ready state is restored.
