[0002] The sample analyzer needs to confirm the instrument status before performing sample analysis or within a set time period.

DETAILED DESCRIPTION

[0023] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It is understandable that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some structures related to the present application are shown in the accompanying drawings, rather than all structures. 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.

[0024] 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.

[0025] Reference to "embodiments" herein means that the specific features, structures, or characteristics described in conjunction with the embodiments may be included in each embodiment of the present application. The appearance of the phrase in various places 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.

[0026] When the sample analyzer is performing normal sample testing, in order to determine whether the results measured by the instrument are accurate and reliable, a fixed-value product is used to perform testing before, during or after the sample test, and the test value of the fixed-value product is compared with the known value of the fixed-value product. If the error between the test value and the known value is small, it indicates that the sample analyzer is in normal condition; if the error between the test value and the known value is large, it indicates that the sample analyzer is out of control.

[0027] The present application provides a sample analyzer that can store fixed-value products and automatically test them without human intervention, thus saving labor costs and improving detection efficiency. In addition, in the prior art, improper manual operation can easily affect the detection value of the fixed-value product, which can easily lead to misjudgment of the state of the sample analyzer. The sample analyzer of the present application can ensure the accuracy and consistency of the test results of the fixed-value product, reduce misjudgment of the state of the sample analyzer, and thus improve the reliability of the sample analyzer. The structure of the sample analyzer and its quality control test method will be introduced in detail below.

[0028] See also Figure 1 As shown, Figure 1 1 is a schematic diagram of the structure of an embodiment of a sample analyzer provided in the present application. Specifically, the sample analyzer 10 includes: a fixed-value product storage unit 11, a sample transport unit 12 and an analysis unit 13.

[0029] like Figure 1 As shown, the fixed-value product storage unit 11 is arranged on one side of the sample transport unit 12, wherein the fixed-value product storage unit 11 can be arranged separately from the sample transport unit 12. That is, the fixed-value product storage unit 11 and the sample transport unit 12 are arranged independently, which is convenient for the maintenance and replacement of the fixed-value product storage unit 11. In other embodiments, the fixed-value product storage unit 11 can also be arranged integrally with the sample transport unit 12.

[0030] Furthermore, the fixed value product storage unit 11 is provided with a storage area 111 and a rewarming area 112, and the storage area 111 is used to store the fixed value products. Specifically, a plurality of storage positions 1111 may be provided in the storage area 111, and the sample tubes containing the fixed value products are placed on the storage positions 1111 to achieve the storage of the fixed value products. The fixed value products generally need to be stored for a specified time at a specific ambient temperature, such as a 2-8°C environment. Therefore, the storage area 111 can set the storage temperature as needed to store the fixed value products therein for a long time.

[0031] The rewarming zone 112 is arranged on one side of the storage area 111, and the rewarming zone 112 is used to rewarm the fixed value product under preset conditions. A rewarming position (not shown in the figure) can be provided in the rewarming zone 112, and the sample tube containing the fixed value product is placed in the rewarming position and rewarmed under the set rewarming temperature and time conditions. The rewarming zone 112 can be arranged on one side of the storage area 111 close to the sample transport unit 12, so that the rewarming zone 112 is closer to the sample transport unit 12, shortening the moving distance of the fixed value product after rewarming. The number of storage positions 1111 in the storage area 111 and the rewarming positions in the rewarming zone 112 are not specifically limited in this application.

[0032] Furthermore, the fixed-value product storage unit 11 also includes a driving member 113 , which is used to move the fixed-value product from the storage area 111 to the rewarming area 112 , and is also used to move the rewarmed fixed-value product to the sample transport unit 12 .

[0033] For example, the driving member 113 may include a gripper, which is used to grab a sample tube containing a fixed value item from the storage area 111 and place it in the rewarming area 112. After the fixed value item is rewarmed, the gripper can place the sample tube containing the fixed value item on the sample transport unit 12.

[0034] The sample transport unit 12 is disposed at one side of the fixed-value product storage unit 11. The sample transport unit 12 is used to transport the sample along the injection direction.

[0035] The analysis unit 13 is provided with a sample suction position corresponding to the sample transport unit 12. When the normal sample is detected, the sample transport unit 12 moves the normal sample to the sample suction position, and the analysis unit 13 is used to detect the normal sample at the sample suction position. During the quality control test, the sample transport unit 12 moves the fixed value product to the sample suction position, and the analysis unit 13 is used to detect the fixed value product at the sample suction position to obtain the detection value of the fixed value product. Among them, the normal sample is the user's sample to be detected.

[0036] like Figure 2 As shown, based on the sample analyzer 10 of any of the above embodiments, the quality control test method of the sample analyzer 10 includes:

[0037] S31: Obtain quality control test instructions.

[0038] S32: Control the driving component to move the fixed-value products in the storage area to the re-temperature area to re-temperature the fixed-value products.

[0039] S33: Control the driving component to move the rewarmed fixed value sample to the sample transport unit;

[0040] S34: Control the sample transport unit to move the rewarmed fixed value sample to the sample suction position of the analysis unit.

[0041] S35: Control the analysis unit to detect the fixed-value products at the sample suction position.

[0042] In the present application, the fixed value product is stored in the fixed value product storage unit 11. When the sample analyzer 10 needs to perform a quality control test, a quality control test instruction can be issued to the sample analyzer 10. In other embodiments, the sample analyzer 10 can also set a quality control test condition. When the sample analyzer 10 reaches the quality control test condition, the quality control test instruction is automatically triggered. For example, the quality control test condition can be that the usage time of the sample analyzer 10 reaches a preset time, or the number of times the sample analyzer 10 is turned on exceeds a preset number of times. After the sample analyzer 10 obtains the quality control test instruction, the driver 113 moves the fixed value product in the storage area 111 to the rewarming area 112, so that the fixed value product is rewarmed in the rewarming area at the set rewarming temperature and time. When the fixed value product is rewarmed, the driver 113 moves the fixed value product to the sample transport unit 12, and the sample transport unit 12 moves the fixed value product after rewarming to the sample suction position. The analysis unit 13 detects the fixed value product at the sample suction position to obtain the detection value of the fixed value product.

[0043] After obtaining the test value of the fixed value product, the test value of the fixed value product is compared with the known value. When the error between the test value and the known value is within an acceptable range, it can be considered that the state of the sample analyzer 10 is normal. When the error between the test value and the known value is not within the acceptable range, it can be considered that the state of the sample analyzer 10 is abnormal.

[0044] The sample analyzer 10 of the present application can store fixed-value products without storing them in other external environments, which facilitates unified management of fixed-value products. When performing quality control tests, the sample analyzer 10 can automatically complete the sampling, rewarming, loading, testing and other processes of the fixed-value products without manual participation, reducing the manual operation process and improving detection efficiency. In addition, it can reduce the misjudgment of the state of the sample analyzer 10 caused by improper manual operation and improve the reliability of the sample analyzer 10 test.

[0045] Furthermore, if Figure 1 As shown, the fixed value product storage unit 11 can also include a fixed seat storage area 15, which is used to place the fixed seat, and the fixed seat is used to place the fixed value product. The driving member 113 can place the fixed value product after rewarming on the fixed seat, and then move the fixed seat with the fixed value product to the sample transport unit 12, so that the sample transport unit 12 can transport the fixed value product through the fixed seat.

[0046] Optionally, other functional areas may be provided in the fixed value product storage unit 11 according to functional requirements, such as a cleaning liquid storage area (not shown), a bottle cap replacement area (not shown), etc. The cleaning liquid storage area is used to store cleaning liquid, and the bottle cap replacement area is used to replace bottle caps. They are not listed one by one here.

[0047] like Figure 1 , Figure 3As shown, the sample analyzer 10 further includes a sample mixing unit 16 and a scanning unit 17 .

[0048] Specifically, the sample mixing unit 16 is provided with a mixing position corresponding to the sample transport unit 12, and the scanning unit 17 is provided with a scanning position corresponding to the sample transport unit 12. In this embodiment, the sample suction position, the mixing position and the scanning position are arranged at intervals from each other. Alternatively, in other embodiments, at least two of the sample suction position, the mixing position and the scanning position share the same position, for example, the mixing position and the sample suction position are located at the same position.

[0049] The sample transport unit 12 transports the fixed-value product to the scanning position, and the scanning unit 17 is used to scan the identification of the fixed-value product at the scanning position to obtain the identification information of the fixed-value product. The identification of the fixed-value product can be pasted on the sample tube loaded with the fixed-value product, and the identification can be a QR code or a barcode, etc. The identification information may include the name, shelf life, remaining quantity and other information of the fixed-value product. When the identification information of the fixed-value product meets the test conditions, for example, the name and shelf life of the fixed-value product meet the requirements, the sample transport unit 12 can transport the fixed-value product to the analysis unit for the next step of operation.

[0050] The sample mixing unit 16 is used to mix the fixed value product or normal sample at the mixing position. Specifically, the sample mixing unit 16 mixes the fixed value product at the mixing position in the second mode, and the sample mixing unit 16 mixes the normal sample at the mixing position in the first mode. In other words, the mixing mode of the normal sample and the mixing mode of the fixed value product of the sample mixing unit 16 are different. Compared with the first mode, the mixing speed of the second mode is slower and the mixing time is longer. Since the storage time of the fixed value product is longer, the texture of the fixed value product may be more brittle than the normal sample. For example, the storage time of the fixed value product of the blood cell is relatively long and it is more brittle than the general blood sample. Excessive mixing speed may cause cell rupture. Therefore, the mixing speed of the fixed value product is slower when mixing, which reduces the damage to the fixed value product, and the mixing time is longer so that the fixed value product can be fully mixed. It is understandable that some fixed value products may not be mixed before testing, such as the fixed value product of a specific protein may not be mixed.

[0051] After the sample mixing unit 16 has finished mixing the fixed value product, the sample transport unit 12 moves the mixed fixed value product to the sample suction position so that the analysis unit 13 can detect it.

[0052] After the test is completed, the sample transport unit 12 is also used to return the fixed-value products after the test to one side of the fixed-value product storage unit 11, and the driving member 113 is also used to move the fixed-value products after the test to the fixed-value product storage unit 11. Specifically, after the fixed-value product test is completed, the mixing unit 16 can put the fixed-value products after the test back to the fixed seat of the sample transport unit 12, and the sample transport unit 12 then transports the fixed seat to one side of the fixed-value product storage unit 11. The driving member 113 puts the fixed-value products after the test back into the fixed-value product storage unit 11 to automatically recycle and sort the fixed-value products after the test.

[0053] Specifically, when the fixed-value product after the test meets the storage conditions, for example, the remaining amount and shelf life of the fixed-value product meet the requirements, the driver 113 puts the fixed-value product after the test back to the storage area 111 for storage, so that the fixed-value product after the test can be used next time. When the fixed-value product after the test does not meet the storage conditions, for example, the remaining amount and shelf life of the fixed-value product do not meet the requirements, the driver 113 can temporarily store the fixed-value product after the test in the rewarming area 112, and wait until the sample analyzer 10 completes all the fixed-value product tests, and then move the fixed-value products in the rewarming area 112 that do not meet the storage conditions to the unloading area 19. Specifically, the driver 113 can move the fixed-value products in the rewarming area 112 that do not meet the storage conditions to the fixed seat, and the driver 113 moves the fixed seat to the sample transport unit 12, and the sample transport unit 12 moves the fixed-value products that do not meet the storage conditions to the unloading area 19 of the sample analyzer 10, and the user can process the fixed-value products in the unloading area 19 that do not meet the storage conditions.

[0054] In other embodiments, a recycling area (not shown) may also be set in the fixed-value product storage unit 11, and the fixed-value products that do not meet the storage conditions can be directly placed in the recycling area (not shown) through the driving member 113 so that the user can process them.

[0055] Alternatively, if Figure 3 As shown, the fixed-value product storage unit 11 may further include a mixing device 14, and the mixing device 14 is used to mix the fixed-value products in the re-temperature zone 112 according to a preset mode.

[0056] During the rewarming process of the fixed value product, the mixing device 14 is controlled to mix the fixed value product in the rewarming zone according to a preset mode. For example, during the rewarming process of the fixed value product, the mixing device 14 can mix the fixed value product at intervals to make the heating of the fixed value product more uniform, speed up the rewarming process, shorten the rewarming time, and thus improve the efficiency of the quality control test. Compared with the mixing of the mixing unit 16 before the test, the mixing amplitude of the mixing device 14 during the rewarming process is smaller and the speed is slower. Since the temperature of the fixed value product during the rewarming process is low and the texture of the fixed value product is brittle, low-speed and small-amplitude mixing can avoid the fixed value product from being damaged during the rewarming process.

[0057] Furthermore, if Figure 3 As shown, a special mixing device 14 can be added, and the mixing device 14 can be set in the rewarming zone 112, or set on one side of the rewarming zone 112. The driving member 113 moves the fixed value product in the rewarming zone 112 to the mixing device 14 according to a preset frequency, so that the mixing device 14 mixes the fixed value product. Specifically, during the rewarming process of the fixed value product, the driving member 113 transports the fixed value product in the rewarming process to the mixing device 14 for mixing at intervals. For example, the driving member 113 moves the fixed value product in the rewarming zone 112 to the mixing device 14 for mixing every 2 minutes, so that the fixed value product is evenly heated and the rewarming time is shortened.

[0058] In other embodiments, the mixing device 14 may also be a driving member 113, that is, during the rewarming process of the fixed value product, the driving member 113 also takes into account the mixing operation during the rewarming process. Specifically, the driving member 113 may grab the fixed value product in the rewarming process according to a preset frequency, and mix it by horizontal reciprocating motion and / or vertical up and down motion. In this way, the rewarming process can be accelerated and hardware costs can be saved.

[0059] Furthermore, if Figure 3As shown, the sample analyzer 10 further includes a loading area 18, which is located at one side of the sample transport unit and is used to load normal samples and fixed-value products. A pusher is provided in the loading area 18, and the pusher is used to push the normal samples and fixed-value products loaded on the loading area 18. The process of storing the fixed-value products in the storage area 111 can be: placing the fixed-value products in the loading area 18 of the sample analyzer 10, and the pusher (not shown) in the loading area 18 pushes the fixed-value products in the loading area 18 to the sample transport unit 12. For example, the fixed-value products can be placed on a fixed seat, and then the fixed seat is placed in the loading area 18, and the fixed seat in the loading area 18 is pushed to the sample transport unit 12 by the pusher in the loading area 18. The sample transport unit 12 transports the fixed-value product to the scanning position, and the scanning unit 17 scans the identification information of the fixed-value product. When it is confirmed to be a fixed-value product, the sample transport unit 12 transports the fixed-value product to one side of the fixed-value product storage unit 11, and the driving member 113 moves the fixed-value product to the storage area 111 of the fixed-value product storage unit 11 to store the fixed-value product, and transmits the stored fixed-value product information to the analysis unit 13 for storage.

[0060] In other embodiments, the user may store the fixed-value product information directly by scanning the identification of the fixed-value product or entering information, and manually place the fixed-value product directly into the storage area 111 of the fixed-value product storage unit 11, and enter the location information by specifying the location.

[0061] The following is an example to illustrate the quality control test process of the sample analyzer 10. Figure 4As shown, in a specific embodiment, when the sample analyzer 10 reaches the set test conditions of the fixed value product or receives a test instruction issued by the user, the driver 113 grabs the fixed value product to be tested from the storage area 111 and puts it into the rewarming area 112, so that the fixed value product is rewarmed under the set rewarming temperature and time conditions. After the rewarming is completed, the driver 113 grabs the fixed value product that has been rewarmed and puts it on the fixed seat. The driver 113 then grabs the fixed seat and puts it on the sample transportation unit 12. The sample transportation unit 12 transports the fixed value product to the scanning position, and the scanning unit 17 scans and confirms the fixed value product at the scanning position. The confirmed fixed value product is further transported to the mixing position, and the mixing unit 16 mixes the fixed value product after the scan is confirmed. The mixing unit 16 uses a second mode for mixing the fixed value product. Different from the first mode of normal sample mixing, the second mode has a slower mixing speed and a longer mixing time. The analysis unit 13 tests the fixed-value product after mixing. After the test is completed, the mixing unit 16 puts it back on the fixed-value product fixing seat, and the sample transport unit 12 transports it back to one side of the fixed-value product storage unit 11. For the unused fixed-value products, the driving member 113 can retract them to the storage area 111 again, and temporarily store the used fixed-value products in the rewarming area 112. After all the fixed-value products are tested, they are sent to the unloading area 19 through the fixing seat for processing by the user. The fixing seat of the fixed-value product can be set with a special label, and the user can place it in the sample loading area 18 of the sample analyzer 10. After being transported to the scanning position by the sample transport unit 12 for identification, it can be recovered into the fixed-value product storage unit 11.

[0062] After obtaining the test result of the fixed-value product, the test result of the fixed-value product can be compared with the known value pre-stored for the fixed-value product. If the error between the test value and the known value is within the allowable range, it is judged that the state of the sample analyzer 10 is normal and the sample test can be performed normally; if the error between the test value and the known value exceeds the allowable range, it is judged that the state of the sample analyzer 10 is abnormal.

[0063] In summary, the testing process of the sample analyzer 10 of the present application on the fixed-value product does not require human participation, reduces the manual operation process, saves labor costs, improves detection efficiency, and can avoid the misjudgment of the sample analyzer 10 being out of control due to improper manual operation of the fixed-value product (for example, improper shaking), thereby improving the reliability of the quality control detection of the sample analyzer 10.

[0064] This application is also applicable to dual machines and assembly lines. The connection method is similar to that of a single machine and will not be repeated here.

[0065] 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.
