DETAILED DESCRIPTION

[0022] 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 to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application.

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.

[0024] 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.

[0025] When the sample analyzer is testing a normal sample, in order to determine whether the results measured by the instrument are accurate and reliable, a fixed-value product is used to test the sample 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. Among them, the normal sample is the sample to be tested by the user.

[0026] The present application provides a storage device for a fixed-value product, a sample analysis system, and a control method thereof. The storage device for a fixed-value product provided by the present application can independently store the fixed-value product, that is, the storage device can work independently, and when the sample analyzer is powered off, the storage device can still maintain a normal working state to ensure that the storage temperature of the internal fixed-value product is normal. After the sample analyzer is turned on, the storage device can communicate with the sample analyzer to synchronize the storage information of the fixed-value product and improve the reliability of the storage information of the fixed-value product. The storage device, the sample analysis system, and the control method thereof will be introduced in detail below.

[0027] See also Figure 1 As shown, Figure 1 1 is a schematic diagram of the structure of an embodiment of a storage device for fixed-value products provided in the present application, wherein the storage device 10 for fixed-value products is provided with a storage area 11, a rewarming area 12 and a control module 17. Optionally, the storage device 10 may also be provided with other functional areas according to its functions, such as: a tube rack storage area 14, a cleaning liquid storage area 15 and a bottle cap replacement area 16. A driving member 18, a first transport mechanism 19 and a mixer 13 may be provided in the storage device 10.

[0028] The storage area 11 is used to store fixed-value products. Specifically, a plurality of storage positions 111 may be provided in the storage area 11, and the storage positions 111 are used to place sample tubes containing fixed-value products. The number of storage positions 111 may be increased or decreased according to the storage requirements of the fixed-value products, and the number of storage positions 111 is not limited here. The temperature in the storage area 11 may be set according to the properties of the fixed-value products. The storage area 11 is generally a relatively low-temperature area. For example, the temperature in the storage area 11 may be 2-8 degrees Celsius to preserve the fixed-value products for a long time.

[0029] The rewarming zone 12 is used to rewarm the fixed value product. After the fixed value product is stored at a low temperature, it is generally rewarmed before use, for example, to room temperature. The rewarming zone 12 can be a relatively high temperature area, for example, the temperature in the rewarming zone 12 can be 25-40 degrees Celsius. A rewarming position 121 can be provided in the rewarming zone 12, and the rewarming position 121 is used to place a sample tube containing the fixed value product. The number of rewarming positions 121 can be increased or decreased according to demand.

[0030] The control module 17 establishes a communication connection with the host module of the sample analyzer, and the control module 17 is used to obtain the first storage information of the fixed value product in the storage device 10, and send the first storage information to the host module of the sample analyzer. That is, the control module 17 can interact with the host module of the sample analyzer to exchange the storage information of the fixed value product.

[0031] The storage device 10 stores first storage information of the fixed-value product, including but not limited to the batch number, bottle number, shelf life, bottle opening date, bottle opening validity period, number of uses, number of remaining uses, items, storage hole positions, cumulative rewarming time, target value, etc. of the fixed-value product.

[0032] Specifically, the first storage information of the fixed-value product can be entered manually. A scanning module (not shown) can also be set in the storage device 10, and the identification code, such as a barcode or a QR code, can be obtained by scanning the scanning module, or by reading an RFID (Radio Frequency Identification) card, etc. This method can simplify the manual operation process and ensure that the information transmission process is accurate and reliable.

[0033] The storage device 10 of the present application can independently store the fixed-value products. When the sample analyzer is turned off and powered off, the storage device 10 can still maintain a normal working state to ensure that the storage temperature of the fixed-value products stored inside is normal. After the sample analyzer starts working, the storage device 10 can communicate with the sample analyzer to synchronize the storage information of the fixed-value products and improve the reliability of the storage information of the fixed-value products.

[0034] Optionally, the control module 17 can also record the usage of the fixed-value product, and update the first storage information according to the usage record of the fixed-value product. In this way, the occurrence of loss of control during the storage and use of the fixed-value product can be reduced. The control module 17 can also send the updated first storage information to the host module of the sample analyzer to synchronize the storage information of the fixed-value product in the host module of the sample analyzer with that in the storage device 10.

[0035] Optionally, the control module 17 can also receive second storage information of the fixed-value product sent by the host module of the sample analyzer. The control module 17 can update the first storage information stored in the storage device 10 based on the second storage information. In this way, the information of the fixed-value product stored in the storage device 10 can be corrected to improve the accuracy of the storage information of the fixed-value product.

[0036] The cleaning liquid storage area 15 is used to store cleaning liquid, which is used to clean the liquid path of the sample analyzer. When the sample analyzer needs to soak or clean the liquid path, the storage device 10 can provide it with cleaning liquid.

[0037] The bottle cap replacement area 16 is used to replace the bottle cap of the sample tube containing the fixed value product. Since the sample tube containing the fixed value product may be punctured multiple times for sample aspiration, debris may be generated when the puncture is repeated many times, and the debris may block the needle or leak liquid. Therefore, the bottle cap of the sample tube of the fixed value product can be replaced regularly, for example, after puncturing 3-5 times, a bottle cap is replaced to improve the reliability of the storage of the fixed value product.

[0038] The tube rack storage area 14 is used to store tube racks, and the tube racks can be used to place sample tubes containing fixed value products. The storage device 10 can transfer the fixed value products to the sample analyzer through the tube racks.

[0039] The driving member 18 is used to move the fixed value product in the storage device 10. The first transport mechanism 19 can be docked with the transport mechanism in the sample analyzer, and the first transport mechanism 19 is used to transfer the fixed value product to the sample analyzer. The driving member 18 can be a three-dimensional gripper, and the three-dimensional gripper can also operate the tube rack to transfer the fixed value product.

[0040] The mixer 13 can shake the fixed value product during the rewarming process to make the fixed value product evenly heated and accelerate the rewarming process. The mixer 13 can be located in the rewarming zone 12 or on one side of the rewarming zone 12. In other embodiments, the mixer 13 may not be provided in the storage device 10, but the fixed value product during the rewarming process is shaken by the driving member 18, so that the structure of the storage device 10 can be simplified and the hardware cost can be saved.

[0041] When the storage device 10 needs to transfer the fixed value product to the sample analyzer, the driver 18 can grab the sample tube containing the fixed value product in the storage area 11 and move it to the rewarming position 121 in the rewarming area 12 to rewarm the fixed value product. During the rewarming process, the driver 18 can grab the fixed value product into the mixer 13 at regular intervals to mix the fixed value product and speed up the rewarming process of the fixed value product. After the fixed value product is rewarmed, the driver 18 moves the fixed value product to the tube rack in the tube rack storage area 14, and the driver 18 moves the tube rack containing the fixed value product to the first transport mechanism 19, and the first transport mechanism 19 moves the tube rack containing the fixed value product to the sample analyzer. When the sample analyzer needs cleaning liquid, the drive 18 can also place the container bottle filled with cleaning liquid in the cleaning liquid storage area 15 on the tube rack in the tube rack storage area 14. The drive 18 places the tube rack containing cleaning liquid on the first transport mechanism 19. The first transport mechanism 19 transports the cleaning liquid to the sample analyzer to provide cleaning liquid for the sample analyzer.

[0042] The storage device 10 of the present application can ensure that the storage and rewarming processes of the fixed value product are performed under strict monitoring, reducing the process of manual operation and reducing the manual workload. The storage device 10 can also automatically store and use the information of the fixed value product, so that the fixed value product can be used accurately, reducing the waste of the fixed value product, and improving the working efficiency and accuracy of the sample analyzer.

[0043] The application also provides a sample analysis system, see Figure 2 As shown, the sample analysis system 100 includes a storage device 10 for a fixed-value product and a sample analyzer 20 according to any one of the above embodiments.

[0044] The sample analyzer 20 is disposed at one side of the storage device 10 , and the storage device 10 can provide the sample analyzer 20 with fixed-value products.

[0045] The sample analyzer 20 includes a host module 21, which establishes a communication connection with the control module 17 in the storage device 10. The host module 21 of the sample analyzer 20 and the control module 17 of the storage device 10 can exchange information to synchronize the storage information of the fixed value product.

[0046] like Figure 3 As shown, the method for information interaction between the sample analyzer 20 and the storage device 10 includes:

[0047] S11: The control module of the storage device sends the first storage information of the fixed-value product to the host module of the sample analyzer.

[0048] S12: The host module compares the first storage information with the second storage information of the fixed-value product stored in the host module.

[0049] S13: When the host module confirms that the first storage information and the second storage information are inconsistent, the host module updates the second storage information in the host module according to the first storage information, or the host module sends the second storage information to the control module so that the control module updates the first storage information in the storage device according to the second storage information.

[0050] When the storage device 10 and the sample analyzer 20 are interacting with each other, the host module 21 receives the first storage information of the fixed-value product sent by the control module 17. After receiving the first storage information, the host module 21 compares the first storage information with the second storage information of the fixed-value product stored therein. When the host module 21 confirms that the first storage information and the second storage information are consistent, the synchronization process of the fixed-value product information of the host module 21 and the control module 17 is completed. When the host module 21 confirms that the first storage information and the second storage information are inconsistent, the host module 21 can directly update the second storage information stored therein according to the first storage information, or the host module 21 sends the second storage information to the control module 17, so that the control module 17 updates the first storage information in the storage device 10 according to the second storage information.

[0051] In another embodiment, Figure 4 As shown, the process of information interaction between the sample analyzer 20 and the storage device 10 may also include:

[0052] S21: The control module of the storage device sends the first storage information of the fixed-value product to the host module of the sample analyzer.

[0053] S22: The host module compares the first storage information with the second storage information of the fixed-value product stored in the host module.

[0054] S23: When the host module confirms that the first storage information and the second storage information are inconsistent, a query is sent to the user as to whether the first storage information is trusted.

[0055] S24: When the host module receives the trust instruction, the host module updates the second storage information in the host module according to the first storage information.

[0056] S25: When the host module receives the untrusted instruction, the host module sends the second storage information to the control module, so that the control module updates the first storage information in the storage device according to the second storage information.

[0057] In this embodiment, when the first storage information and the second storage information are inconsistent, the user confirms whether to trust the first storage information. When the user trusts the first storage information, the host module 21 and the control module 17 are synchronized to the first storage information. When the user does not trust the first storage information, the host module 21 and the control module 17 are synchronized to the second storage information.

[0058] In the above embodiment, the storage information of the fixed-value product can be stored in the sample analyzer 20 and the storage device 10 at the same time, which is conducive to improving the reliability of information storage. When the storage information in the host module 21 or the control module 17 is lost, the information can be restored from the party that has not been lost, so as to improve the reliability of the sample analysis system 100 and reduce the waste of the fixed-value product. In other embodiments, the storage information of the fixed-value product can be stored only in the host module 21 or the control module 17, and the host module 21 and the control module 17 can realize information mutual query and synchronization.

[0059] Furthermore, if Figure 2 As shown, the sample analyzer 20 also includes a second transport mechanism 22, and the second transport mechanism 22 and the first transport mechanism 19 are arranged side by side, and the host module 21 is provided with a sample suction position (not shown) corresponding to the second transport mechanism 22. The first transport mechanism 19 is used to transfer the fixed value product to the second transport mechanism 22, and the second transport mechanism 22 is used to move the fixed value product to the sample suction position, so that the host module 21 detects the fixed value product at the sample suction position. Preferably, the first transport mechanism 19 and the second transport mechanism 22 can be both conveyor belts, and the first transport mechanism 19 can smoothly transfer the tube rack containing the fixed value product to the second transport mechanism 22, so that the second transport mechanism 22 can transfer the fixed value product. In this way, the fixed value product can be smoothly transferred between the sample analyzer 20 and the storage device 10.

[0060] Optionally, the storage process of the fixed-value product can be: the fixed-value product is placed on a tube rack and loaded into the loading area 24 of the sample analyzer 20, and is transported to the scanning unit 23 by the second transport mechanism 22. After being identified as a fixed-value product tube rack and a fixed-value product, it will be transported to the storage device 10 for storage, so as to realize automatic storage of the fixed-value product. In other embodiments, the fixed-value product can also be directly placed manually in the storage area 11 for storage.

[0061] The following is an example of the operation process between the storage device 10 and the sample analyzer 20 when performing quality control tests on fixed-value products. When the sample analyzer 20 reaches the set test conditions for the fixed-value products or receives a test instruction issued by the user, the host module 21 sends the usage information of the fixed-value products to the control module 17. The usage information of the fixed-value products includes the type of fixed-value products, the number of tests, etc. The control module 17 of the storage device 10 selects the fixed-value products that need to be rewarmed from the storage area 11 according to the usage information of the fixed-value products received, controls the driving member 18 to grab the fixed-value products that need to be tested from the storage area 11, and puts them into the rewarming area 12. The rewarming time can be 20-30 minutes. During the rewarming process, the fixed-value products can be shaken by the mixer 13 to make the fixed-value products more evenly heated. After the rewarming is completed, the driving member 18 grabs the rewarmed fixed-value product and puts it on the tube rack in the tube rack storage area 14. The driving member 18 grabs the tube rack and puts it into the first transportation mechanism 19. The first transportation mechanism 19 transfers the tube rack containing the fixed-value product to the second transportation mechanism 22. The second transportation mechanism 22 can transport the fixed-value product to the scanning unit 23 of the sample analyzer 20 for scanning and identification. When it is confirmed that it is a fixed-value product that needs to be tested by the sample analyzer 20, the confirmed fixed-value product enters the fixed-value product testing process. For example, the second transportation mechanism 22 transports the fixed-value product to the sample suction position so that the host module 21 can detect it. The fixed-value product that has completed the test can be transported to the storage device 10 through the second transportation mechanism 22. Specifically, the second transportation mechanism 22 transfers the fixed-value product that has completed the test to the first transportation mechanism 19, and the driving member 18 places it in the storage area 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 20 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 20 is abnormal.

[0063] In summary, in the sample analysis system of the present application, the storage device 10 can independently store the fixed-value products, and the storage device 10 and the sample analyzer 20 can exchange information, so that the fixed-value products can be used accurately and the waste of fixed-value products can be reduced. Moreover, the testing process of the fixed-value products does not require manual participation, which reduces the manual operation process, saves labor costs, and improves detection efficiency and detection accuracy.
