[0026] The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0028] It should be noted that when a component is referred to as being "fixed to" or "mounted on" another component, it may be directly on the other component or there may be a central component. When a component is referred to as being "disposed on" another component, it may be directly on the other component or there may be a central component. As used herein, the term "and / or" includes all and any combinations of one or more of the relevant listed items.

[0029] Typically, a large number of consumables are required during library construction, such as sample containers (such as sample tubes) for holding samples, connector containers (connector tubes) for holding connectors, pipette tips for transferring liquids, reagent containers (such as reagent bottles) for holding reagents, and waste liquid containers for holding waste liquids. To facilitate transfer and use during library construction, these consumables require specially customized carriers. This results in a large number of carriers, which are relatively scattered and require more space on the library construction instrument. Furthermore, there are problems such as inconvenient operation and long transfer distances during the consumable transfer process.

[0030] In order to solve the above problems, an embodiment of the present application provides a consumable carrier, which can be used to place consumables used in the library construction process, but is not limited to this, and can also be used to place consumables in other biochemical or medical testing processes.

[0031] See also Figure 1 and Figure 2 As shown, refer to Figure 6 The consumable carrier 100 includes an integrated carrier body 10, and the carrier body 10 includes multiple functional areas, which can be used to place a variety of consumables. By adopting an integrated solution, the areas for placing different consumables are integrated into the integrated carrier body 10, and the overall consumable carrier 100 is small in size and occupies little space, thereby improving space utilization. The multiple functional areas include a first type of area 20 and a second type of area 30, the first type of area 20 has a plurality of first through holes, and the second type of area 30 has a plurality of second through holes, the hole depth of the first through hole is less than the hole depth of the second through hole, and the first through hole and the second through hole are configured to place different consumables. Specifically, the first through-hole is configured to accommodate a first type of consumable, which may be a container for holding a sample (which may be a tubular container, such as a sample tube, centrifuge tube, reagent bottle, etc.). The sample may be, for example, a biological sample required for biochemical analysis (such as a human blood sample, tissue sample, or saliva sample), a connector, a variety of reagents, and other liquid samples. It may also be a sample carrier for carrying a biological sample (such as magnetic beads), or a reaction product, but is not limited thereto. The second through-hole is configured to accommodate a second type of consumable, which may be a pipette tip used for liquid transfer in conjunction with a pipette.

[0032] In some embodiments, the first type of area 20 includes: a sample area 1, a transfer area 2, a processing area 3, a product area 4, and a reagent area 5. The sample area 1 may include at least one first through-hole 11 for placing a container 200 containing a sample. The transfer area 2 may include at least one first through-hole 21 for temporarily storing a container 200 containing a sample or an empty container 200. The processing area 3 may include at least one first through-hole 31 for placing a container 200 containing a mixed sample, wherein the mixed sample may be subjected to a mixing operation or separation and purification operation in the processing area 3. The product area 4 may include at least one first through-hole 41 for placing a container 200 containing a product formed after the reaction. The reagent area 5 may include at least one first through-hole 51 for placing a container 300 containing a reagent. Specifically, the container 200 may be a container of the same or similar structure, such as a sample tube or a centrifuge tube, and the container 300 may be a reagent tube specifically for holding reagents. It is understood that the container 200 can be used to hold reagents, but is not specifically for holding reagents. Such containers 200 and 300 are used to load samples. The volume of the containers 200 and 300 can be selected according to the size of the sample, and the corresponding apertures of the first through holes 11, 21, 31, 41 and 51 can be designed according to the outer diameters of the containers 200 and 300. The depth H1 of the first through holes 11, 21, 31, 41 and 51 should be sufficient to stably fix the containers 200 and 300.

[0033] In some embodiments, the sample area 1, transfer area 2, processing area 3, product area 4 and reagent area 5 all include multiple corresponding first through holes, which can simultaneously process multiple amounts of samples, thereby improving the throughput of sample processing, and can also simultaneously process different samples to improve sample processing efficiency.

[0034] In some embodiments, during a biochemical reaction (e.g., library construction), the volume of a single container 200 determines the volume of a single reaction system. The consumable carrier 100 is compatible with containers 200 of different volumes, covering consumable requirements ranging from 100 μL to 10 mL. For example, in this embodiment, when the volume of a single container 200 is 1.5 mL, the amount of sample added is 2 / 3 of the container 200. At this time, a single reaction system can reach 1 mL, thereby effectively increasing the amount of reaction product (e.g., the amount of library preparation).

[0035] In some embodiments, the sample area 1, the transfer area 2, and the product area 4 are all provided with identification marks. By providing identification marks in the sample area 1, the transfer area 2, and the product area 4, different functional areas can be quickly distinguished, and the container 200 can be easily taken in and out. The processing area 3 is used during the use of the consumable carrier 100 (for example, during the library construction process). Identification marks are provided in the sample area 1, the transfer area 2, and the product area 4. The processing area 3 does not need to be provided with an identification mark, which can also quickly distinguish the functional areas. It is understandable that the identification marks corresponding to the sample area 1, the transfer area 2, and the product area 4 can be the same or different.

[0036] In some embodiments, the identification mark can be an identification groove provided in the corresponding area, such as the identification groove 12 located in the sample area 1, the identification groove 22 located in the transfer area 2, and the identification groove 42 located in the product area 4. Specifically, the identification grooves 12, 22, and 42 can be annular structures surrounding the periphery of all the first through holes 11, 21, and 41 in the corresponding area, so as to separate and distinguish the sample area 1, the transfer area 2, and the product area 4.

[0037] Please refer to Figure 3 and Figure 5 , the portion of the carrier body 10 corresponding to the first type of area 20 has a hollow structure 16, that is, the hole depth H1 of the first through holes 11, 21, 31, 41 and 51 is relatively small, so as to reduce the weight of the consumable carrier 100. In addition, the provision of the hollow structure 16 in part of the first type of area 20 also facilitates the installation of other functional modules during the use of the consumable carrier 100, so as to improve space utilization. In some embodiments, the processing area 3 has an installation cavity 32, which is part of the hollow structure 16. According to the function of the processing area 3, the installation cavity 32 can be used to accommodate a mixing module or a separation and purification module, wherein the mixing module can provide power for the mixed sample in the mixing container 200, and the separation and purification module can provide force for the mixed sample in the separation and purification container 200.

[0038] Please also refer to Figure 1 、 Figure 5 and Figure 6As shown, the second type of area 30 may include a tip area 6, which includes a plurality of second through holes 61. The plurality of second through holes 61 can be used to place a plurality of tips 400. Assuming that the length of the tip 400 is H, the hole depth H2 of the second through hole 61 is greater than or equal to 1 / 2H. The second type of area 30 can be used to place unused tips 400, and can also be used to place used tips 400. Specifically, during the use of the consumable carrier 100, after the pipette cooperates with the tip 400 to transfer the liquid sample, the pipette will also insert the used tip 400 into the original second through hole 61. At this time, there will be residual liquid sample on the outer wall of the used tip 400. By setting the hole depth H2 of the second through hole 61 to be longer, the risk of the tip 400 coming into contact with other tips 400 when taking out or putting into the second through hole 61 can be reduced, thereby reducing the risk of cross contamination.

[0039] In some embodiments, a removable protective film (not shown) is provided on the surface of the tip area 6 to prevent liquid from the outside of the tips 400 from stained on the tip area 6, thereby facilitating the recycling of the consumable carrier 100. Specifically, the protective film can be provided on the back side of the tip area 6, that is, the surface near the tip of the tip 400 after the tip 400 is placed in the second through-hole 61 of the tip area 6. This prevents liquid from the tip of the used tip 400 from stained on the back side of the tip area 6. It is understood that protective films can also be provided on both the front and back sides of the tip area 6 to prevent liquid from the outside of the tip 400 from stained on the surface of the tip area 6 during the placement of a used tip 400.

[0040] Please refer again Figure 1 、 Figure 2 and Figure 6 As shown, depending on actual usage needs, the container 200 for loading the sample can be open or have a sealing cover 201. When the container 200 is a sealed container with a sealing cover 201, the multiple functional areas also include a third type of area 40. The third type of area 40 can include a sealing cover temporary storage area 7. The sealing cover temporary storage area 7 has a plurality of grooves 71. The grooves 71 are configured to temporarily store the sealing cover 201 removed from the container 200.

[0041] In some embodiments, the sealing cap temporary storage area 7 is disposed near the sample area 1 and the processing area 3 to facilitate placement and removal of the sealing cap 201 during operation.

[0042] In some embodiments, the depth of the groove 71 can be designed according to the height of the sealing cover 201 actually used, so as to facilitate grasping of the sealing cover 201 .

[0043] It is understandable that the portion of the carrier body 10 corresponding to the third type of area 40 may also be configured as a hollow structure to further reduce the weight of the consumable carrier 100 .

[0044] Please refer to Figure 1 、 Figure 4 and Figure 6 As shown, the plurality of functional areas may further include a fourth type of area 50, which may include a waste liquid area 8 having a waste liquid tank 81, which is configured to accommodate waste liquid generated during sample processing.

[0045] In some embodiments, a cover plate 82 is provided on the waste liquid tank 81, and a waste liquid hole 83 connected to the waste liquid tank 81 is provided on the cover plate 82. The suction head for transferring waste liquid can be extended into the waste liquid tank 81 through the waste liquid hole 83 to discharge the waste liquid, which can effectively reduce problems such as aerogel contamination caused by waste liquid splashing.

[0046] In some embodiments, the cover 82 can be removably attached to the waste liquid tank 81. For example, the cover 82 can be locked into the opening of the waste liquid tank 81 through an interference fit, which can improve the stability of the cover 82 and prevent it from being lifted when the pipette tip is removed. It is understood that the waste liquid tank 81 can be removably disposed in the waste liquid area 8. When the waste liquid tank 81 is full of waste liquid, the waste liquid tank 81 can be removed and the waste liquid can be processed.

[0047] Please refer again Figure 1 、 Figure 2 As shown, the carrier body 10 further includes a marking area 60, which is used to locate the consumables located in the multiple areas. Specifically, the marking area 60 includes two marking positioning grooves 91. The carrier body 10 can be rectangular, and the two marking positioning grooves 91 can be located at both ends of a diagonal line of the carrier body 10. For example, the two marking positioning grooves 91 can be cross coordinate positioning grooves set in a diagonal direction of the carrier body 10, such as Figure 1 After obtaining the plane coordinates of the cross-coordinate positioning groove, the plane coordinates of each consumable on the carrier body 10 can be directly obtained, eliminating the need to locate each consumable one by one, facilitating operation and improving consumable transfer efficiency. It is understood that the specific structure and location of the alignment positioning groove 91 can be designed based on actual needs and the specific shape of the carrier body 10, and is not limited to the above positions and shapes.

[0048] like Figure 1 As shown, the carrier body 10 may further include an identification area 70 , on which an identification code 92 is provided, such as a QR code. By identifying the identification code 92 , sample information can be obtained, thereby effectively avoiding incorrect sample use.

[0049] The consumable carrier 100 can be a disposable consumable, requiring no cleaning process, thus reducing cross contamination caused by reuse. The consumable carrier 100 can also be recycled. During actual use, one only needs to add the required consumables to the designated location to start the fully automated sample processing process.

[0050] like Figures 1 to 3 As shown, combined Figure 6 Based on the amount of different consumables used and the ease of transferring them during use, the aforementioned functional areas can be rationally arranged to maximize space utilization, shorten the consumable transfer path, and simplify operations. In some embodiments, the sample area 1, transfer area 2, processing area 3, and product area 4 in the first-type area 20 are concentrated together to facilitate sample processing and shorten the travel time. For example, the sample area 1 and processing area 3 are arranged side by side, the transfer area 2 and product area 4 are arranged side by side, the transfer area 2 is adjacent to the sample area 1, and the product area 4 is adjacent to the processing area 3. The third-type area 40 is located near the first-type area 20. Specifically, the sealing cap temporary storage area 7 is located near the sample area 1 and processing area 3. This facilitates the removal and placement of the sealing cap 201 and shortens the travel time. The second-type area 30 is also located near the first-type area 20. Specifically, the tip area 6 is located near the transfer area 2 and product area 4 to facilitate the removal and placement of the tips 400 during sample processing. The reagent area 5 in the first-type area 20 can be positioned adjacent to the pipette tip area 6 in the second-type area 30. This allows the pipette tip 400 to be directly moved to the reagent area 5 after installation to access the reagent, shortening the process. The waste liquid area 8 can be positioned relatively far from the first-type area 20 within the carrier body 10 to prevent waste liquid from contaminating the sample. Specifically, the waste liquid area 8 is positioned adjacent to the reagent area 5. It will be appreciated that the different functional areas on the carrier body 10 can be increased, decreased, or repositioned as needed.

[0051] Please refer to Figure 1 、 Figure 3 and Figure 5 As shown, combined Figure 6The carrier body 10 may include a first portion 101 and a second portion 102 connected to each other. The first type of region 20 is located in the first portion 101, and the second type of region 30 is located in the second portion 102. The first portion 101 includes a first surface 13 and a second surface 14 disposed opposite each other. First through-holes 11, 21, 31, 41, and 51 are formed through the first and second surfaces 13, 14. The first surface 13 extends to the second portion 102. The second portion 102 also includes a third surface 15 disposed opposite the first surface 13. Second through-holes 61 are formed through the first and third surfaces 15 of the second portion 102. The thickness of the second portion 102 is greater than that of the first portion 101. The first surface 13 corresponding to the first portion 101 and the first surface 13 corresponding to the second portion 102 are substantially coplanar. The second surface 14 and the third surface 15 are located on the same side of the first surface 13. Thus, the second surface 14 and the side surface of the second portion 102 enclose a hollow structure 16 corresponding to the first type of region 20. By designing the second portion 102 to be thicker, the depth H2 of the second through-hole 61 in the second-type area 30 is increased, facilitating the placement of the pipette tip 400. Designing the first portion 101 to be thinner reduces the weight of the consumable carrier 100 while still ensuring the securement of the containers 200 and 300. Furthermore, the hollow structure 16 facilitates the installation of other functional modules.

[0052] In some embodiments, the carrier body 10 can be a rectangular structure. It can be understood that the carrier body 10 is not limited to a rectangular structure, and can also adopt other structures such as circular, rectangular, etc. according to actual space requirements, or can adopt an irregular structure to facilitate space layout and improve space utilization.

[0053] In some embodiments, the outer sidewall of the carrier body 10 is provided with an anti-slip portion 17 to facilitate the transfer of the carrier body 10. Specifically, the anti-slip portion 17 can be a ridge protruding from the sidewall, or a groove.

[0054] See also Figure 6 As shown, the embodiment of the present application further provides a sample processing device 1000 using the aforementioned consumable carrier 100, the sample processing device 1000 comprising: a workbench 500 and the aforementioned consumable carrier 100 located on the workbench 500. The sample processing device 1000 can be a library preparation instrument used for library preparation during gene sequencing.

[0055] Specifically, the workbench 500 includes a platform 501, a support 502 mounted on the platform 501, a robot 503 mounted on the support 502, and a cover-opening station 504 and a mixing station 505 mounted on the platform 501. The robot 503 is equipped with integrated grippers and a pipette. The consumable carrier 100 is mounted on the platform 501, and the cover-opening station 504 and the mixing station 505 are located at one end of the platform 501.

[0056] In some embodiments, in conjunction with Figure 1 The sealing cap temporary storage area 7 on the consumable carrier 100 for temporarily storing the sealing cap 201 can be set close to the opening station 504 and the mixing station 505, which is beneficial to shorten the transfer distance and thus optimize the transfer path.

[0057] The following takes the library building process as an example to further describe the use process of the aforementioned consumable carrier 100.

[0058] like Figure 6 As shown, combined Figure 1 and Figure 2 As shown, the reagent container 300 (such as a reagent bottle) filled with the reagent and the pipette tip 400 (TIP head) matched with the pipette are placed in the reagent area 5 and the pipette tip area 6 of the consumable carrier 100 respectively. It can be understood that the reagent container 300 and the pipette tip 400 can also be pre-packaged in the corresponding areas of the consumable carrier 100. The container 200 (such as a sample tube) containing the biological sample is placed in the sample area 1. After the above actions are completed, the consumable carrier 100 is placed on the carrier table 501 of the workbench 500. The manipulator 503 is respectively moved to the alignment positioning groove 91 (cross coordinate positioning groove) on the carrier body 10, and the plane (X, Y axis) coordinate position of each consumable, sample, reagent, etc. on the consumable carrier 100 is obtained. The Z-axis coordinate position is obtained according to the actual usage scenario of each consumable, sample, and reagent.

[0059] After obtaining the spatial (X, Y, Z axis) coordinates of each position on the consumable carrier 100, the gripper on the manipulator 503 grabs the sample tube in the sample area 1 and takes it to the opening station 504 and the mixing station 505 to open, close, and mix. During the process, the lid that is unscrewed is temporarily placed in the groove 71 of the sealing cover temporary storage area 7. Afterwards, the manipulator 503 grabs the sample tube and takes it to the processing area 3 for magnetic washing. During the process, when reagents need to be added to the sample tube, the manipulator 503 can be moved to the tip area 6, and the pipette 400 can be used to load the upper pipette, and then the manipulator 503 can be transferred to the reagent area 5 to absorb the reagent and load it into the sample tube. The used waste liquid is injected into the waste liquid tank 81 of the waste liquid area 8 through the pipette combined with the pipette tip 400. After the library is built, the manipulator 503 places the sample tube containing the product in the product area 4 of the consumable carrier 100 and returns to the origin. Finally, the construction of the entire library is completed by removing the sample tube containing the product from the consumable carrier 100.

[0060] The consumables carrier 100 and the sample processing device 1000 provided in the embodiment of the present application integrate the areas for placing different consumables to form an integrated consumables carrier 100. Compared with traditional consumables carriers, it takes up less space, significantly improves the space utilization of the sample processing device 1000, is conducive to the miniaturization of the sample processing device 1000, and the stroke of consumables transfer is reduced, further reducing the volume of the sample processing device 1000. Different consumables are integrated on the same consumables carrier 100 for transfer, and one-stop consumables loading avoids the time loss of repeated loading, optimizes the process, simplifies the operation, and is more efficient. In addition, the consumables carrier 100 provided in the present application can replace multiple customized carriers, improve resource utilization, and reduce R&D investment costs.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention.
