Description

Technical Field

[0001] This invention relates to the field of biological sample detection, and more specifically to a sample processing device. Background Technology

[0002] A sample processing device is an automated system for processing biological samples, widely used in biological sample detection fields such as nucleic acid extraction, IGF-1 detection, GHb detection, and NGS library preparation. Different sample processing components are typically included in the device for different detection types. Taking nucleic acid extraction as an example, a sample processing device generally includes pipetting devices, magnetic racks, shaking devices, heating and drying devices, and reagent tanks. These multiple components work together according to a pre-set experimental procedure to extract and purify biological samples for subsequent detection and analysis.

[0003] When processing biological samples using sample processing devices, consumables typically need to be replaced periodically to ensure the cleanliness of the sample processing. Taking nucleic acid extraction as an example, consumables include pipette tips and deep-well plates for holding reagents. After use, users need to identify the type of consumable, retrieve it from the preparation area, and then replace it. This manual operation is not only inconvenient and inefficient, but also prone to contaminating the consumables and affecting the sample testing results.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] To address the technical problem that existing sample processing devices cannot achieve automated management of sample consumables, this invention provides a sample processing device. The sample processing device includes: a base frame; sample processing modules arranged on the base frame; and a consumable management component, which includes a sensing module, a stacking module, and a transfer module. The sensing module is arranged on each sample processing module to detect whether the sample consumables in that module are depleted. The stacking module is arranged on the base frame and includes multiple spare sample consumables. The transfer module is movably fixed to the base frame, and when the sensing module detects that the sample consumables in the corresponding sample processing module are depleted, the transfer module is configured to grab one of the spare sample consumables and transfer it to the sample processing module to replace the depleted sample consumable.

[0006] The sample processing device of this invention includes a base frame, sample processing modules, and a consumable management component. The sample processing modules are arranged on the base frame to perform different processing on samples according to the type of sample testing. The consumable management component includes a sensing module, a stacking module, and a transfer module. The sensing module is arranged on each sample processing module to detect whether the sample consumables in the sample processing module are depleted. The stacking module is arranged on the base frame and includes multiple spare sample consumables. The transfer module is movably fixed to the base frame, and when the sensing module detects that the sample consumables in the corresponding sample processing module are depleted, the transfer module is configured to grab a spare sample consumable and transfer it to the sample processing module to replace the depleted sample consumable. Through the cooperation of the sensing module, stacking module, and transfer module, spare sample consumables can be transferred to the sample processing module in a timely manner after the sample consumables in the sample processing module are depleted, realizing automated management of sample consumables and improving the automation level of the sample processing device. Furthermore, since both the sample processing modules and the consumable management component are arranged on the base frame, the transfer distance of the sample consumables can be shortened, improving the efficiency of transfer and replacement.

[0007] In the preferred embodiment of the above-described sample processing device, the sample processing module includes a mounting plate and sample processing components detachably arranged on the mounting plate, and the sensing module is fixed to the mounting plate. The detachable arrangement of the sample processing components on the mounting plate facilitates assembly and disassembly, and allows for flexible selection of appropriate sample processing components according to the needs of different detection types. Furthermore, the fixed sensing module on the mounting plate allows for convenient detection of whether the sample consumables in the sample processing module are depleted, enabling timely replacement.

[0008] In a preferred embodiment of the above-described sample processing device, a plurality of spring contacts and a plurality of fixing posts are provided on the mounting plate. The plurality of spring contacts and the plurality of fixing posts are spaced apart from each other along the circumference of the mounting plate and together form an installation area that can constrain the sample processing component. The cooperation of the spring contacts and fixing posts facilitates the installation and positioning of the sample processing component on the mounting plate.

[0009] In a preferred embodiment of the above-described sample processing device, the transfer module includes: a three-dimensional platform fixed to the base frame; and a robotic arm movably fixed to the three-dimensional platform and configured to grasp the sample consumables and the spare sample consumables. Through this configuration, the grasping and transfer of the sample consumables and the spare sample consumables can be conveniently achieved.

[0010] In a preferred embodiment of the above-described sample processing device, the robotic arm is further equipped with a barcode scanner for scanning the information code of the spare sample consumables to obtain the type of the spare sample consumables. The barcode scanner facilitates the identification of the spare sample consumables' information, enabling the accurate picking of the appropriate spare sample consumables.

[0011] In a preferred embodiment of the above-described sample processing device, the robotic arm includes mechanical grippers for holding the spare sample consumables, and a scanner mounting plate for fixing the scanner is provided on the mechanical grippers. The mechanical grippers facilitate the gripping of both the sample consumables and the spare sample consumables. The scanner, mounted on the scanner mounting plate fixed to the mechanical grippers, allows for convenient and accurate scanning of the information codes on the spare sample consumables.

[0012] In a preferred embodiment of the above-described sample processing device, the stacking module includes: a fixed base disposed on the base frame; and a limiting plate configured to extend vertically upward along the circumferential edge of the fixed base, thereby defining a chamber for accommodating the spare sample consumables together with the fixed base. This configuration allows the spare sample consumables to be stably and neatly stacked on the fixed base, facilitating their gripping by the transfer module.

[0013] In the preferred embodiment of the above-described sample processing device, the limiting plate includes a left limiting plate and a right limiting plate arranged opposite to each other on both sides of the fixed base, and each of the left and right limiting plates is a U-shaped member with its opening facing upwards. This configuration results in a simple structure for the limiting plate, facilitating its manufacturing.

[0014] In a preferred embodiment of the above-described sample processing device, a detection device is provided on the limiting plate to detect the height of the spare sample consumable within the chamber. This design allows for convenient detection of the height of the spare sample consumable within the chamber, enabling the robotic arm to accurately position and grasp the spare sample consumable.

[0015] In the preferred embodiment of the above-described sample processing device, the sample consumables and the spare sample consumables respectively include pipette tips, shallow-well plates, PCR plates, and deep-well plates. This arrangement enriches the types of consumables and meets the needs of consumables during sample processing. Attached Figure Description

[0025] To address the technical problem that existing sample processing devices cannot achieve automated management of sample consumables, this invention provides a sample processing device 1. The sample processing device 1 includes: a base frame 10; a sample processing module 20 disposed on the base frame 10; and a consumable management component 30, which includes a sensing module 31, a stacking module 32, and a transfer module 33. The sensing module 31 is disposed on each sample processing module 20 to detect whether the sample consumables 23 located in the sample processing module 20 are exhausted. The stacking module 32 is disposed on the base frame 10 and includes multiple spare sample consumables 326. The transfer module 33 is movably fixed to the base frame 10, and when the sensing module 31 detects that the sample consumables 23 in the corresponding sample processing module 20 are exhausted, the transfer module 33 is configured to grab a spare sample consumable 326 and transfer it to the sample processing module 20 to replace the exhausted sample consumable 23.

[0026] Figure 1 This is a schematic diagram of an embodiment of the sample processing device of the present invention. Figure 1 As shown, in one or more embodiments, the sample processing device 1 of the present invention includes a base frame 10, multiple sample processing modules 20, and a consumable management component 30. The multiple sample processing modules 20 are arranged on the base frame 10 to meet the sample processing requirements of different detection types (including but not limited to nucleic acid extraction, IGF-1 detection, GHb detection, NGS library preparation, etc.). The consumable management component 30 is also arranged on the base frame 10 to facilitate timely replacement of exhausted sample consumables 23 on the sample processing modules 20.

[0027] like Figure 1 As shown, in one or more embodiments, the base frame 10 includes a base plate 11 and a support plate 12 fixed to the base plate 11. The base plate 11 provides suitable mounting space for the sample processing module 20 and the consumable management component 30. In one or more embodiments, the base plate 11 is a generally rectangular plate structure. Alternatively, the base plate 11 may also be square, circular, or other suitable shapes. The base plate 11 may be made of a suitable metal material (e.g., stainless steel, cast iron, etc.) to give it good mechanical properties. Figure 1As shown, the support plate 12 is fixed to the rear side of the base plate 11 and includes a left support plate 121 and a right support plate 122 spaced apart from each other in the left-right direction. Both the left support plate 121 and the right support plate 122 are substantially perpendicular to the base plate 11. The methods of fixing the left support plate 121 and the right support plate 122 to the base plate 11 include, but are not limited to, screwing, snap-fitting, and welding. The left support plate 121 and the right support plate 122 are used to support and install the transfer module 33 of the consumable management component 30. Alternatively, the support plates 12 can also be configured with other suitable structures and quantities, as long as they can stably support and install the transfer module 33.

[0028] like Figure 1 As shown, multiple sample processing modules 20 are arranged at intervals on the base plate 11 for processing biological samples. In one or more embodiments, each sample processing module 20 includes a mounting plate 21 and a sample processing component 22 detachably fixed to the mounting plate 21. The mounting plate 21 is fixed to the base plate 11 of the frame 10. The fixing method may be, but is not limited to, screwing, welding, etc.

[0029] Figure 2 This is a schematic diagram of the structure of an embodiment of the mounting plate of the sample processing module in the sample processing device of the present invention. For example... Figure 2 As shown, in one or more embodiments, the mounting plate 21 is a generally rectangular flat plate. The mounting plate 21 can be made of suitable metal materials (e.g., stainless steel, aluminum alloy, etc.) or resin materials (e.g., PP, PE, etc.) to give it good mechanical properties. Based on Figure 2 As shown, two spring tabs 211 and four fixing posts 212 spaced apart from each other along their circumferential edges are formed on the upper surface of the mounting plate 21. These two spring tabs 211 and four fixing posts 212 together form a mounting area 213 for constraining the sample processing component 22. Specifically, each fixing post 212 is configured to extend approximately vertically upward from the upper surface of the mounting plate 21. Furthermore, the fixing post 212 has a generally tapered shape, allowing the sample processing component 22 to be easily inserted into the mounting area 213 and abut against the fixing post 212. Each spring tab 211 faces the center of the mounting plate 21, so that when the sample processing component 22 is arranged in the mounting area 213, the elasticity of the spring tab 211 itself can apply a pushing force to the sample processing component 22, thereby, together with the fixing posts 212, stably and securely fixing the sample processing component 22 to the mounting plate 21. It should be noted that the number and arrangement of the spring clips 211 and the fixing posts 212 can be adjusted according to actual needs, as long as the sample processing component 22 can be firmly fixed.

[0030] See also Figure 1The sample processing component 22 is fixed to the base plate 11 of the frame 10 via a mounting plate 21. The sample processing component 22 includes, but is not limited to, a magnetic rack device, a heating and drying device, a shaking device, a pipette tip box, a reagent slot, a sample slot, and a blood vessel clamping device. When performing different types of tests on biological samples, a suitable sample processing component 22 can be selected according to actual needs. For example, when performing nucleic acid extraction, the sample processing component 22 can be a pipette tip box, a reagent slot, a sample slot, a magnetic rack device, a heating and drying device, and a shaking device. When performing Ghb detection, the sample processing component 22 can be a pipette tip box, a shaking device, a heating and drying device, and a blood vessel clamping device. In addition, suitable sample consumables 23 are placed on the sample processing device 221 of the sample processing component 22. Sample consumables 23 include pipette tips, shallow-well plates, PCR plates, or deep-well plates. Before processing the sample, the sample consumables 23 need to be placed on the corresponding sample processing component 22 in advance, for example, placing the pipette tip on the pipette tip box in advance. During the sample processing, the sample consumables 23 may be used up and need to be replaced in time to avoid contaminating the sample, and to continue the current biological sample processing or to prepare for the next biological sample processing.

[0031] like Figure 1 and Figure 2 As shown, in one or more embodiments, the consumable management component 30 includes a sensing module 31, a stacking module 32, and a transfer module 33. The sensing module 31 is arranged on each sample processing module 20 to detect whether the sample consumables 23 in the corresponding sample processing module 20 are exhausted. (Continue to see...) Figure 2 In one or more embodiments, the sensing module 31 is fixed to the upper surface of the mounting plate 21. The sensing module 31 forms a communication connection with the controller (not shown) of the sample processing device 1 so as to transmit the detected results to the controller.

[0032] See also Figure 1 In one or more embodiments, four stacked modules 32 are arranged at intervals from each other in the front-to-back direction on the left side of the base plate 11 of the base frame 10. Alternatively, the number of stacked modules 32 may be set to other suitable numbers, more or less than four, such as three, five, etc. Alternatively, the stacked modules 32 may also be arranged in other suitable positions on the base plate 11, such as the right side, etc.

[0033] Figure 3 This is a schematic diagram of an embodiment of the stacking module in the sample processing device of the present invention. Figure 3As shown, in one or more embodiments, each stacking module 32 includes a fixed base 321 and a limiting plate 322 to form a chamber 323 for accommodating spare sample consumables 326. The spare sample consumables 326 are arranged in a stacked manner within the chamber 323. The spare sample consumables 326 include pipette tips, shallow well plates, PCR plates, or deep well plates, etc. The fixed base 321 is disposed on the base plate 11 of the base frame 10. In one or more embodiments, the fixed base 321 includes components such as a fixed base plate 3211, a support column 3212, and a limiting and fixing plate 3213. The fixed base plate 3211 is a generally rectangular plate structure. The fixing methods between the fixed base plate 3211 and the base plate 11 include, but are not limited to, screwing, welding, etc. In one or more embodiments, a vertically extending inwardly extending limiting groove (not shown in the figure) is formed on the upper surface of the fixed base plate 3211 to receive the support base 325 for supporting the spare sample consumable 326. Four support columns 3212 are respectively arranged at the four corners of the fixed base plate 3211. Each support column 3212 has a generally cylindrical shape and is generally perpendicular to the fixed base plate 3211. A limiting fixing plate 3213 extending generally in the front-back direction is provided at the top of the support columns 3212 on the left and right sides respectively.

[0034] like Figure 3 As shown, the limiting plate 322 extends vertically upward along the circumferential edge of the fixed base 321, and together with the fixed base 321, the limiting plate 322 defines a chamber 323 for receiving the spare sample consumable 326. In one or more embodiments, the limiting plate 322 includes a left limiting plate 322a and a right limiting plate 322b arranged opposite to each other on the left and right sides of the fixed base 321. The left limiting plate 322a is fixed to the limiting fixing plate 3213 located on the left side, while the right limiting plate 322b is fixed to the limiting fixing plate 3213 located on the right side. In one or more embodiments, each of the left limiting plate 322a and the right limiting plate 322b is an upward-opening U-shaped member (not shown in the figure). Specifically, each of the left limiting plate 322a and the right limiting plate 322b includes a first limiting post 3221 and a second limiting post 3222 spaced apart from each other in the front-rear direction, and a connecting plate 3222 disposed between the first limiting post 3221 and the second limiting post 3222. The connecting plate 3222 is located below the first limiting post 3221 and the second limiting post 3222, such that the entire left limiting plate 322a or right limiting plate 322b has a generally U-shaped shape. The first limiting post 3221 and the second limiting post 3222 have a generally L-shaped cross-section to constrain the sequentially stacked spare sample consumables 326.

[0035] See also Figure 1 and Figure 3A support base 325 is arranged on a fixed base 321 and inserted into a cavity 323 formed by the fixed base 321 and a limiting plate 322. In one or more embodiments, the support base 325 is inserted into a limiting groove located on a fixed base plate 3211 to improve the stability of the installation. Figure 1 As shown, the support base 325 is a box with an open top, allowing the spare sample consumable 326 located at the bottom (i.e., the spare sample consumable 326 closest to the support base 325) to extend into the interior of the support base 325 through the top opening, thereby avoiding interference. Furthermore, the spare sample consumable 326 at the bottom rests against the circumferential edge of the support base 325 at the top, and then other spare sample consumables 326 are stacked sequentially on top of the bottom spare sample consumable 326.

[0036] See also Figure 3 In one or more embodiments, each stacking module 32 further includes a detection device 324. The detection device 324 is used to detect the height of the spare sample consumables 326 within the chamber 323. In one or more embodiments, a detection device 324 corresponding to the height of each layer of spare sample consumables 326 is provided on the first limiting post 3221 of the left limiting plate 322a to detect whether the spare sample consumables 326 at the corresponding height are used. The number of detection devices 324 in the stacking modules 32 used to place different types of spare sample consumables 326 is different. When the height of the spare sample consumables 326 is higher, the number of layers of the corresponding type of spare sample consumables 326 that can be stacked on the stacking module 32 is reduced, and the number of detection devices 324 in the stacking module 32 is also reduced accordingly. In addition, the detection device 324 forms a communication connection with the controller of the sample processing device 1 so as to transmit the detection results to the controller, thereby controlling the movement of the transfer module 33.

[0037] like Figure 1 As shown, in one or more embodiments, the transfer module 33 includes a three-dimensional platform 331 and a robotic arm 332. The three-dimensional platform 331 is fixed to the support plate 12. The robotic arm 332 is movably fixed to the three-dimensional platform 332 via a drive motor (not shown). In one or more embodiments, the three-dimensional platform 331 includes an X-axis slide rail 3311, a Y-axis slide rail 3312, and a Z-axis slide rail 3311. Based on Figure 1As shown, the X-axis slide rail 3311 is fixed to the top of the left support plate 121 and the right support plate 122 of the base frame 10 and extends generally in the left-right direction. The Y-axis slide rail 3312 extends generally in the front-back direction, and the rear end of the Y-axis slide rail 3312 is slidably fixed to the X-axis slide rail 3311. The Z-axis slide rail 3313 extends generally in the up-down direction, and the middle part of the Z-axis slide rail 3313 is slidably fixed to the Y-axis slide rail 3312. The robot arm 332 is movably fixed to the Z-axis slide rail 3313 of the three-dimensional platform 331. That is, the robot arm 332 can move up and down along the Z-axis slide rail 3313 under the drive of the drive motor. Therefore, with the above configuration, the robot arm 332 can flexibly move in the left-right, front-back, and up-down directions to grasp and transfer spare sample consumables 326. In one or more embodiments, the robotic arm 332 includes mechanical grippers 3321 for grasping sample consumables 23 and spare sample consumables 326. The mechanical grippers 3321 can open and close under the drive of a motor to grasp and release the consumables.

[0038] like Figure 1 As shown, in one or more embodiments, the sample processing device 1 of the present invention further includes a barcode scanner 40. The barcode scanner 40 can scan the information code set on the spare sample consumable 326 to obtain the type of the spare sample consumable 326, so that the transfer module 33 can accurately identify the spare sample consumable 326 that matches the exhausted sample consumable 23. In one or more embodiments, a barcode scanner fixing plate 3322 is provided on the mechanical gripper 3321, and the barcode scanner 40 is fixed on the barcode scanner fixing plate 3322 to facilitate and accurately scan the information code on the spare sample consumable 326.

[0039] When the sample processing device 1 of the present invention is in use, the sensing module 31 arranged on the sample processing module 22 will detect in real time whether the sample consumable 23 is exhausted. When the sensing module 31 detects that the sample consumable 23 is exhausted, the controller will drive the transfer module 33 to move to the area where the stacking module 32 is located. The barcode scanner 40 will scan and identify the information code on the spare sample consumable 326. After the controller receives the scanning result, it will compare whether the spare sample consumable 326 matches the exhausted sample consumable 23. If the result is not, the transfer module 33 will continue to move to other stacking modules 32; if the result is yes, the transfer module 33 will be positioned at the stacking module 32. Then, the detection device 324 on the stacking module 32 will detect the spare sample consumable 326 stacked on the top layer of the fixed base 321, so as to drive the robotic arm 332 of the transfer module 33 to accurately grasp the spare sample consumable 326. After the spare sample consumable 326 is picked up, the robotic arm 332 will transfer the spare sample consumable 326 to the corresponding sample processing module 20 under the control of the controller to replace the sample consumable 326.

[0040] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
