Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0022] The terms "first", "second", etc. in this application are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. 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 includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0023] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0024] This application provides a sample analysis system and a control method thereof. Figure 1 and Figure 2 As shown, Figure 1 is a schematic diagram of a framework of an embodiment of a sample analysis system provided by the present application. Figure 2 1 is a schematic diagram of the structure of an embodiment of a sample analysis system provided in the present application. Specifically, the sample analysis system includes: a control unit 10 , a loading unit 11 , a first scanning unit 12 , a sample injection unit 13 and an unloading unit 14 .

[0025] The loading unit 11 is used to load samples (hereinafter referred to as "samples"). Specifically, the loading unit 11 can transport samples through a test tube rack 21, and the test tube rack 21 includes a plurality of sample positions, and the sample positions are used to place samples 22. The loading unit 11 is loaded with a plurality of test tube racks 21 arranged side by side, and each test tube rack 21 is placed with a plurality of samples 22. The loading unit 11 is used to transfer the samples 22 therein to the first scanning unit 12.

[0026] The first scanning unit 12 is used to perform a first scan on the sample 22 to obtain the first sample information. The scanning of the sample 22 by the first scanning unit 12 means that the first scanning unit 12 scans the identification code on the sample tube containing the sample 22, and the identification code can be a QR code or a barcode, etc. After the first sample information of the sample 22 is obtained by the first scanning unit 12, the control unit 10 can obtain the order analysis mode of the sample based on the first sample information, wherein the order analysis mode of the sample refers to the test items that the sample 22 needs to be tested. The control unit 10 can pre-schedule the sample 22 according to the order analysis mode of the sample 22, so as to move the sample 22 to the corresponding injection unit 13 for testing.

[0027] Optionally, the first scanning unit 12 may also perform a first scan on the test tube rack 21 loaded with the sample 22 to obtain the first test tube rack information. The test tube rack code scanning is mainly used to distinguish the types of test tube racks. For example, the types of test tube racks may include: (1) Venous whole blood test tube rack: The test tube rack is used to place venous whole blood samples for sample testing of venous whole blood samples. (2) Micro whole blood test tube rack: The test tube rack is used to place micro whole blood samples for sample testing of micro whole blood samples. (3) Quality control test tube rack: The test tube rack is used to place quality control samples for quality control testing of quality control samples. (4) Cleaning liquid test tube rack: The test tube rack is used to place probe cleaning liquid samples for analyzer immersion maintenance and analyzer shutdown.

[0028] The scanning priority of the first scanning unit 12 for the sample 22 and the test tube rack 21 may be: first scan the test tube rack 21 to obtain the first test tube rack information, and then scan the sample 22 to obtain the first sample tube information. In other embodiments, the scanning priority of the first scanning unit 12 for the sample 22 and the test tube rack 21 may also be: first scan the sample 22 and then scan the test tube rack 21.

[0029] like Figure 2 As shown, the sample injection unit 13 includes at least one sample analyzer 131 and a second scanning unit 132 . The second scanning unit 132 is used to perform a second scan on the sample 22 in the sample injection unit 13 to obtain second sample information. The sample analyzer 131 is used to detect the sample 22 .

[0030] Specifically, the sample introduction unit 13 includes an analysis track 133, and the second scanning unit 132 is disposed on one side of the analysis track 133. The second scanning unit 132 is provided with a scanning position (not shown in the figure) corresponding to the analysis track 133. The second scanning unit 132 is used to perform a second scan on the sample 22 at the scanning position to obtain the second sample information. Optionally, the second scanning unit 132 can also perform a second scan on the test tube rack 21 at the scanning position to obtain the second test tube rack information.

[0031] The unloading unit 14 is used to unload samples that have been tested or samples that do not need to be tested.

[0032] Optionally, the sample analysis system may further include a rotation unit (not shown in the figure), which is used to adjust the travel direction of the sample transmission channel, so that the sample analysis system can adapt to various spaces for setting various units.

[0033] The loading unit 11, the first scanning unit 12, the injection unit 13, and the unloading unit 14 may all include a plurality of tracks. When the plurality of units are arranged along the injection direction A, the tracks can be connected to form a sample transmission channel. In this embodiment, the sample 22 can be loaded from the loading unit 11, passed through the first scanning unit 12, the injection unit 13, and finally unloaded through the unloading unit 14.

[0034] The control unit 10 is connected to the loading unit 11 , the first scanning unit 12 , the sample injection unit 13 and the unloading unit 14 . The control unit 10 can be used to implement the control method of the sample analysis system of any of the following embodiments to schedule and distribute the samples.

[0035] It can be understood that in other embodiments, the number of injection units 13, loading units 11, unloading units 14, etc. can be increased or decreased according to actual needs, and is not specifically limited here.

[0036] The structures of the loading unit 11 , the first scanning unit 12 , the injection unit 13 , the unloading unit 14 and the rotating unit are within the scope that can be understood by those skilled in the art and will not be described in detail herein.

[0037] The control unit 10 is connected to the loading unit 11, the first scanning unit 12, the sample injection unit 13 and the unloading unit 14. The control unit 10 is used to implement the control method of any of the following embodiments to schedule and allocate sample analysis so that the items to be tested and the actual test items of the sample are consistent, thereby improving the reliability of the sample analysis system.

[0038] Please refer to 3. Figure 3 : is a flow chart of an embodiment of a control method of a sample analysis system provided by the present application. Specifically, the control method includes:

[0039] S31: Control the loading unit to move the sample along the injection direction so that the sample moves to the first scanning unit, and control the first scanning unit to perform a first scan on the sample to obtain first sample information.

[0040] When the sample analysis system detects the sample, the control unit controls the loading unit to move the sample to the first scanning unit. Specifically, the control unit controls the loading unit to move the sample along the injection direction so that the sample moves to the first scanning unit. The loading unit can be loaded with a plurality of test tube racks arranged side by side, and each test tube rack contains a plurality of samples. The loading unit transfers the sample to the first scanning unit through the test tube rack.

[0041] When the test tube rack moves into the first scanning unit, the control unit controls the first scanning unit to perform a first scan on the sample, thereby obtaining the first sample information. Specifically, the control unit can control the first scanning unit to scan the identification code on the sample tube loaded with the sample, and the identification code can be a two-dimensional code or a barcode storing the sample information. The first scanning unit scans the identification code outside the sample tube to obtain the first sample information.

[0042] S32: Based on the first sample information, control the first scanning unit to move the sample along the injection direction so that the sample moves to the corresponding injection unit, and control the second scanning unit in the corresponding injection unit to scan the sample for the second time to obtain second sample information.

[0043] The control unit can obtain the order analysis mode of the sample based on the first sample information, and pre-allocate the sample based on the order analysis mode to transport the sample to the corresponding injection unit so that the corresponding sample analyzer can detect the corresponding item on the sample.

[0044] The first scanning unit may fail to scan the sample, that is, the sample fails to scan the barcode for the first time. When the first scanning unit fails to scan the sample, the control unit may pre-allocate the sample according to a preset allocation mode to pre-allocate the sample to the corresponding injection unit. The preset allocation mode may be an allocation mode preset by the user or a system default allocation mode.

[0045] The control unit controls the first scanning unit to move the sample along the injection direction, and after the sample is moved to the corresponding injection unit, the control unit controls the second scanning unit in the injection unit to scan the sample for the second time to obtain second sample information.

[0046] When the second scanning unit fails to scan the sample for the second time, that is, the sample fails to scan the code for the second time in the sampling unit, the sample analysis system will assign sample information to the sample according to the preset rules to obtain the second sample information. For example, when the second scanning unit fails to scan the sample for the second time, the control unit assigns a new number to the sample: InvalidX (X is the order of the day). The user can set the local analysis mode corresponding to the newly assigned sample information.

[0047] S33: Based on the first sample information and the second sample information, obtain final scanning information of the sample.

[0048] After acquiring the first sample information and the second sample information, the control unit obtains final scanning information of the sample based on a set allocation rule.

[0049] The control unit pre-assigns samples based on the first sample information obtained by the first scanning unit, which is not an important basis for the final order analysis mode. After the second scanning unit scans the sample for the second time, the control unit compares the first sample information with the second sample information, that is, performs a second confirmation through the second scanning rule, and obtains the final scanning information of the sample, so that the sample test items and the reagent test items are consistent, thereby improving the reliability of the sample analysis system.

[0050] Furthermore, after the control unit successfully scans the sample with the first scanning unit and the second scanning unit fails to scan the sample, the sample analysis system will assign sample information to the sample according to preset rules based on the second scan to obtain second sample information, and use the second sample information as the final scanning information of the sample.

[0051] If the first scanning unit fails to scan the sample and the second scanning unit fails to scan the sample, the control unit can use the second scan as the basis. The sample analysis system will assign sample information to the sample according to preset rules to obtain second sample information and use the second sample information as the final scanning information of the sample.

[0052] The control unit can use the second scanning unit as the final scanning information of the sample when the first scanning unit successfully scans the sample and the second scanning unit successfully scans the sample and determines that the first sample information and the second sample information are different.

[0053] When the first scanning unit fails to scan the sample but the second scanning unit succeeds in scanning the sample, the control unit may use the second sample information as the final scanning information of the sample based on the second scanning.

[0054] The scheduling rule of the above embodiment is: the second sample information is used as the final scanning information of the sample. In this way, when the sample is transported from the first scanning unit to the second scanning unit, the user can insert the sample or replace the sample. The user can use this rule to conveniently complete the processing of emergency samples without queuing the loading unit, without using a dedicated emergency test tube rack, without completing the emergency sample testing in an offline operation of the assembly line, etc. The operation process of emergency samples is simplified and operation time is saved.

[0055] In other embodiments, when the control unit confirms that the accuracy of the first sample information is greater than the accuracy of the second sample information, the first scan may be used as the final scan information of the sample; when the control unit confirms that the accuracy of the second sample information is greater than the accuracy of the first sample information, the second scan may be used as the final scan information of the sample. Specifically, the control unit may receive a confirmation instruction from the user to confirm the accuracy of the first sample information and the second sample information. In other embodiments, the control unit may also calculate the accuracy of the first sample information and the second sample information according to a corresponding algorithm. In this way, the control unit takes the sample information with higher accuracy as the basis, improves the accuracy of the sample scanning information, reduces the probability that the sample items to be tested do not match the actual test items, and improves the reliability of the sample analysis system.

[0056] S34: Performing distribution detection on the samples based on the final scanning information of the samples.

[0057] After acquiring the final scanning information of the sample, the control unit obtains the order analysis mode of the sample based on the final scanning information of the sample, and then allocates the sample based on the order analysis mode to complete the inspection of the sample.

[0058] The sample analysis system of the present application performs a second scan to confirm the sample, which can reduce the probability that the items to be tested of the sample do not match the actual test items, and improve the reliability of the sample analysis system. Moreover, when the sample analysis system of the present application is testing the sample, the user can add new samples or replace samples during the transportation of the sample, so that the user can complete the emergency sample processing more conveniently. Emergency samples do not need to queue up in the loading unit, do not need to use a dedicated emergency test tube rack, do not need to operate offline on the assembly line, etc., which simplifies the user's operation process and saves operation time.

[0059] Based on the above sample analysis system, the present application also provides another embodiment of a control method for the sample analysis system. In this embodiment, the first scanning unit and the second scanning unit perform a second scan on both the test tube rack and the sample, so as to determine the type of the test tube rack based on the second scanning result of the test tube rack, thereby determining the detection process of the sample analyzer, and determining the order analysis mode of the sample based on the second scanning result of the sample, so as to allocate the sample and complete the detection of the sample. Please refer to Figure 4 As shown, Figure 4 : is a flow chart of another embodiment of a control method of a sample analysis system provided by the present application. Specifically, the control method includes:

[0060] S41: Control the loading unit to move the test tube rack containing the sample along the injection direction so that the test tube rack moves to the first scanning unit, control the first scanning unit to perform a first scan on the test tube rack to obtain first test tube rack information, and control the first scanning unit to perform a first scan on the sample to obtain first sample information.

[0061] In this embodiment, the loading unit transports the samples via a test tube rack, wherein each test tube rack includes a plurality of sample positions for placing the samples. The control unit is used to control the loading unit to move the test tube rack containing the plurality of samples to the first scanning unit.

[0062] The control unit controls the first scanning unit to perform a first scan of the test tube rack therein to obtain the first test tube rack information. The control unit can determine the type of test tube rack based on the test tube rack information. For example, the types of test tube racks include: (1) venous whole blood test tube rack: the test tube rack is used to place venous whole blood samples for sample testing of venous whole blood samples. (2) micro whole blood test tube rack: the test tube rack is used to place micro whole blood samples for sample testing of micro whole blood samples. (3) quality control test tube rack: the test tube rack is used to place quality control material samples for quality control testing of quality control samples. (4) cleaning liquid test tube rack: the test tube rack is used to place probe cleaning liquid samples for sample analyzer immersion maintenance and sample analyzer shutdown. Different types of test tube racks correspond to different types of samples, and the control unit can determine the detection process of the sample analyzer based on the sample type.

[0063] After the first scanning unit fails to scan the test tube rack, the control unit can control the first scanning unit to move the test tube rack in the opposite direction of the injection direction to rotate the test tube rack back to the loading unit. The returned test tube rack continues to queue in the loading unit for detection. The control unit controls the loading unit to transfer the returned test tube rack to the first scanning unit again, and the first scanning unit scans the test tube rack again. When the first scanning unit fails to scan the test tube rack again, the control unit controls the first scanning unit to move the test tube rack in the opposite direction of the injection direction to send the test tube rack to the unloading unit, report the scanning failure fault, and send a reminder message to remind the user that the system has an error and requires manual intervention.

[0064] The control unit is further used to control the first scanning unit to perform a first scan on the sample to obtain first sample information. This step is the same as step S31 and will not be repeated herein.

[0065] The control unit may scan the test tube rack and the sample in the following order: the control unit first scans the test tube rack and then scans the sample. In other embodiments, the control unit may also scan the sample first and then scan the test tube rack.

[0066] S42: Based on the first sample information, control the first scanning unit to move the test tube rack along the injection direction so that the test tube rack moves to the corresponding injection unit, control the second scanning unit in the corresponding injection unit to scan the test tube rack for the second time to obtain the second test tube rack information, and control the second scanning unit in the corresponding injection unit to scan the sample for the second time to obtain the second sample information.

[0067] After acquiring the first sample information, the control unit controls the first scanning unit to move the test tube rack along the injection direction based on the first sample information, so that the test tube rack moves to the corresponding injection unit. After the test tube rack is at the corresponding injection unit, the control unit controls the second scanning unit to scan the test tube rack for the second time to obtain the second test tube rack information. When the second scanning unit fails to scan the sample for the second time, the second test tube rack information may be empty.

[0068] The control unit controls the second scanning unit in the sample injection unit to scan the sample for the second time to obtain the second sample information. The step is the same as step S32 and will not be repeated here.

[0069] S43: obtaining final scanning information of the test tube rack based on the first test tube rack information and the second test tube rack information, and obtaining final scanning information of the sample based on the first sample information and the second sample information.

[0070] After acquiring the first test tube rack information and the second test tube rack information, the control unit compares the first test tube rack information and the second test tube rack information to obtain final scan information of the test tube rack, so that the control unit determines the sample type based on the final scan information of the test tube rack.

[0071] Optionally, the control unit may return the test tube rack to the loading unit after the first scanning unit fails to scan the test tube rack for the first time, so that the test tube rack is queued again in the loading unit and waits for scanning again. If the first scanning unit scans the test tube rack successfully, the first test tube rack information is obtained. When the second control unit scans the test tube rack successfully or fails for the second time, the second test tube rack information is obtained. The first test tube rack information can be used as the final scanning information of the test tube rack. Since the possibility of the test tube rack being lost during transportation is small, the first scanning information of the test tube rack is used as the basis, and there is no need to modify the recorded information of the sample analyzer, thereby improving the detection efficiency of the sample analysis system.

[0072] In other embodiments, the control unit may also use the second test tube rack information as the final scan information of the test tube rack. In this way, the user can add or take out a test tube rack during transportation of the test tube rack, which is convenient for the user to add an emergency test tube rack.

[0073] In other embodiments, the control unit may also calculate the accuracy of the first test tube rack information and the accuracy of the second test tube rack information through a corresponding algorithm, and use the test tube rack information with higher accuracy as the final scan information of the test tube rack. In this way, the accuracy of the final scan information of the test tube rack can be improved.

[0074] The step of obtaining the final scanning information of the sample based on the first sample information and the second sample information is the same as step S33, which will not be repeated here.

[0075] S44: performing distribution testing on the samples based on the final scanning information of the test tube rack and the final scanning information of the samples.

[0076] After obtaining the final scan information of the test tube rack, the control unit obtains the sample type based on the final scan information, and the control unit can set the detection process of the sample analyzer based on the sample type. After obtaining the final scan information of the sample, the control unit determines the order analysis mode of the sample based on the final scan information, so as to allocate the sample for detection based on the order analysis mode.

[0077] In the sample analysis system of the above-mentioned embodiment, the test tube rack and the sample are scanned twice to confirm the information of the test tube rack and the sample twice. The control unit can use the first test tube rack information obtained by the first scan as the final scan information of the test tube rack. In this way, there is no need to change the setting information of the sample analyzer, thereby speeding up the detection efficiency of the sample analysis system. The control unit can use the second sample information obtained by the second scan as the final scan information of the sample. In this way, it supports users to add new samples to empty sample positions in the test tube rack, or replace samples, etc., so that users can complete the processing of emergency samples more conveniently, without the need for loading units to queue up, without the need to use special emergency test tube racks, and without the need for the sample analysis system to operate offline, etc. to complete emergency sample testing, simplifying the user operation process and reducing operation time.

[0078] The above description is only an implementation method of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
