[0006] With the increasing adoption of precision medicine and point-of-care testing, clinical applications of fluorescence immunochromatographic analyzers are demanding higher standards. They require not only excellent detection sensitivity and repeatability, but also portability, ease of operation, automation, and rapid response capabilities. These needs are particularly urgent in emergency rooms, ICUs, primary healthcare institutions, and mobile diagnostic settings. Traditional portable sample analyzers typically use automated sample loading instruments or manual sample introduction. Automated sample loading instruments often have complex sample processing devices that occupy a large space or are exposed externally, making them unsuitable for small sample analyzers. Manual sample introduction requires thorough mixing of blood samples before testing, and single-tube manual injection is inefficient and complex. A single injection station cannot meet the requirements for continuous sample loading, making it unsuitable for emergency scenarios.

[0044] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] In the description of the embodiments of this application, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0046] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0047] Currently, fluorescence immunochromatographic analyzers on the market are mainly divided into two categories: one is large benchtop equipment, which, although possessing high throughput and accuracy, is bulky and heavy, making flexible deployment difficult and unable to meet the needs of rapid point-of-care or on-site testing; the other is handheld or small portable equipment, which, while convenient to carry, has significant shortcomings in functional integration, automation, and the diversity of testing items. These typically require manual steps such as sample addition and reagent strip loading, which are prone to operational errors and cannot support simultaneous detection of multiple indicators. Existing highly automated analyzers often have low integration of functional modules such as sample introduction, puncture, reagent reaction, and detection, resulting in a loose structure that not only occupies a large space but also reduces the stability and reliability of the overall operation. Furthermore, the layout of the existing equipment's user interface is unreasonable, with scattered functional areas, increasing the learning cost for medical staff and the risk of operational errors.

[0048] To address the aforementioned technical problems, this application provides an immunochromatographic analyzer.

[0049] Referring to Figures 1 and 2, the immunochromatographic analyzer provided in this embodiment includes a front panel module 300, a sample processing device 100, and a reagent strip module. A sampling tube inlet 302 and a sampling tube outlet 303 are provided on the operating surface of the front panel module 300. The sample processing device 100 is connected to the sampling tube inlet 302 and is used to receive sampling tubes. The sampling tube on the sample processing device 100 is driven to move from the sampling tube inlet 302 to the sampling tube outlet 303 to discharge the sampling tube. A puncture position 304 is provided along the movement path of the sampling tube. A puncture positioning component 301 is installed above the reagent strip module, which has reagent strips. The puncture positioning component 301 is driven to switch between the puncture position 304 and the reagent strip's dispensing position in the horizontal direction.

[0050] It should be noted that this application provides a compact and highly integrated immunochromatographic analyzer. Its core lies in the modular design that organically integrates the front panel module 300, sample processing device 100, reagent strip module, and puncture positioning component 301. After the sampling tube enters through the sampling tube inlet 302 on the front panel, it is automatically transported to the puncture position 304 by the sample processing device 100. The puncture positioning component 301 performs puncture and sampling at this position, then moves horizontally to the dispensing position on the reagent strip module to complete sample dispensing. Finally, the sampling tube is discharged from the sampling tube outlet 303. This design achieves full automation from sample introduction, puncture, dispensing to tube discharge, avoiding errors caused by manual intervention. Simultaneously, the compact layout and optimized paths of each functional module not only improve the stability and reliability of the entire machine but also consider portability and multi-index detection potential. It effectively solves the shortcomings of existing equipment in terms of automation, integration, and ease of operation, making it suitable for scenarios with high demands for rapid, accurate, and point-of-care testing, such as emergency rooms, ICUs, and primary healthcare facilities.

[0051] The working method of this application embodiment is as follows: The user inserts the sampling tube containing the sample into the sampling tube inlet 302 of the front panel module 300. The sample processing device 100 automatically clamps and drives the sampling tube to move along a preset path to the puncture position 304. At this time, the puncture positioning component 301 located above moves down to puncture and sample the sampling tube. Then, the puncture positioning component 301 moves horizontally to the dispensing position on the reagent strip module and accurately dispenses the sample onto the reagent strip to start the immunochromatographic reaction. After the dispensing is completed, the puncture positioning component 301 resets, and the sample processing device 100 continues to push the sampling tube to the sampling tube outlet 303 for discharge. The whole process does not require manual intervention and realizes fully automated operation from sample injection, puncture and sampling, dispensing reaction to waste tube discharge, which significantly improves detection efficiency, repeatability and operation convenience.

[0052] This application's embodiments significantly improve the detection efficiency, ease of operation, and system stability of the fluorescence immunochromatographic analyzer through a highly integrated modular design and automated process. On the one hand, it achieves fully automated sampling tube insertion, puncture sampling, sample addition, and waste tube discharge without human intervention, effectively avoiding human error and improving detection repeatability and accuracy. On the other hand, the compact layout and optimized movement paths of each functional module not only reduce the overall size of the machine and enhance portability but also support flexible configuration of multi-index reagent strips, meeting the urgent needs of emergency, ICU, and primary healthcare scenarios for rapid, accurate, and bedside testing, overcoming the shortcomings of existing equipment in terms of low automation, loose structure, and complex operation.

[0053] Referring to Figures 1, 3, 4 and 5, as an optional embodiment, a tablet placement port 305 is provided on the operating surface of the front panel module 300; the reagent tablet module includes a tablet assembly 306; the tablet assembly 306 includes a plurality of tablet cavities 307 arranged sequentially along a first direction; the tablet placement port 305 communicates with the tablet cavities 307 for placing tablets 308 into the tablet cavities 307.

[0054] The reagent tablet module includes an incubation component 210, a tablet loading and unloading component 200, and a tablet pick-and-carry component 310. The tablet compartment 308 is provided with a reagent tablet outlet 311 with an opening facing the tablet pick-and-carry component 310. The tablet pick-and-carry component 310 is used to transfer the reagent tablets in the tablet compartment 308 from the reagent tablet outlet 311 to the sample loading position of the tablet loading and unloading component 200. The tablet loading and unloading component 200 is used to push the reagent tablets at the sample loading position into the incubation component 210, and to make the reagent tablets pass through the sample dispensing position.

[0055] It should be noted that, in this embodiment of the application, by setting a tablet placement port 305 in the front panel module 300, the user can sequentially load multiple pre-loaded reagent tablets into the tablet compartment cavities 307 arranged along the first direction in the reagent tablet module, thereby realizing batch storage and orderly management of reagent tablets; the tablet compartment 308 is provided with a reagent tablet outlet 311 facing the tablet pick-and-place assembly 310, the tablet pick-and-place assembly 310 grabs the reagent tablet from the outlet and transfers it to the sample inlet position of the tablet inlet / outlet assembly 200; subsequently, the tablet inlet / outlet assembly 200 pushes the reagent tablet to the incubation assembly 210, and during the pushing process, it passes through the sample drop position below the puncture positioning assembly 301, so that after the puncture positioning assembly 301 completes the sample drop, the reagent tablet immediately enters the incubation assembly 210 for constant temperature reaction. This design, through the coordinated operation of the slide handling assembly 310, the slide loading and unloading assembly 200, and the incubation assembly 210, automates the entire process of reagent slides from storage, retrieval, dispensing to incubation. This not only improves the continuous detection capability of multiple indicators but also enhances the overall integration and ease of operation, effectively supporting the needs of rapid, high-throughput immunochromatographic detection at the bedside.

[0056] The working method of this embodiment is as follows: The user places multiple reagent tablet compartments 308 into the tablet compartment cavities 307 arranged along the first direction in the reagent tablet module through the tablet compartment placement port 305 on the front panel module 300. At the start of the test, the tablet handling assembly 310 picks up a reagent tablet from the reagent tablet outlet 311 of the designated compartment 308 and transfers it to the sample inlet position of the tablet loading / unloading assembly 200. Subsequently, the tablet loading / unloading assembly 200 pushes the reagent tablet to the incubation assembly 210. During the pushing path, the reagent tablet passes the sample dispensing position below the puncture positioning assembly 301. At this time, the puncture positioning assembly 301, having completed puncture sampling, accurately dispenses the sample onto the reagent tablet. After the sample dispensing is completed, the reagent tablet continues to be sent to the incubation assembly 210 for constant-temperature reaction, while the sample processing device 100 completes the puncture and discharge of the sampling tube. The entire process achieves integrated operation of automatic reagent tablet retrieval, automatic sample dispensing, and automatic reaction incubation, significantly improving the automation level, throughput, and reliability of the test.

[0057] Referring to FIG3, as an optional embodiment, the cartridge assembly 306 includes an electric locking member 309 and a position detection switch; when the cartridge 308 is inserted into the cartridge cavity 307, it compresses the spring element provided in the cartridge cavity 307; after the position detection switch detects the cartridge 308, the electric locking member 309 locks the slot provided on the cartridge 308.

[0058] This application embodiment integrates an electric locking component 309, a position detection switch, and a spring element into the tablet compartment assembly 306, constructing an intelligent and reliable installation and fixing mechanism for the tablet compartment 308. When the user inserts the tablet compartment 308 into the tablet compartment cavity 307, the tablet compartment 308 compresses the preset spring element within the cavity, simultaneously triggering the position detection switch. The system then determines that the tablet compartment 308 is correctly positioned. Subsequently, the controller drives the electric locking component 309 to engage with the slot on the tablet compartment 308, achieving automatic locking. This design not only ensures the tablet compartment 308 is stable and reliable during testing, preventing positioning deviations or reagent tablet transfer failures due to loosening, but also achieves automatic identification and safe locking of the tablet compartment 308's status through the linkage of position detection and electric locking. This improves the equipment's intelligence level, operational safety, and operational stability, effectively avoiding operational errors and inefficiencies caused by manual confirmation or manual locking.

[0059] During the testing process, the integrated testing module in the tablet compartment 308 monitors the remaining number of reagent tablets in real time and transmits the information to the front panel module 300, which displays the number of available reagent tablets in the current tablet compartment 308 to the user. When the testing module determines that the reagent tablets in the tablet compartment 308 are exhausted, the user can trigger a replacement command through the front panel module 300. The control system then drives the electric locking component 309 to unlock the slot on the tablet compartment 308. At the same time, the pre-compressed spring element in the tablet compartment cavity 307 releases its elastic potential energy, automatically ejecting the empty tablet compartment 308 from the tablet compartment cavity 307, facilitating quick replacement by the user. The entire process realizes intelligent monitoring of the remaining reagent tablets, depletion warning, and automatic ejection of the tablet compartment 308. This not only improves the ease of operation and human-machine interaction experience but also effectively avoids testing interruptions or misoperations caused by failure to replace reagent tablets in time after they are exhausted. This further enhances the practicality and automation level of the equipment in continuous and efficient bedside testing scenarios.

[0060] Referring to FIG6, as an optional embodiment, the reagent strip assembly 310 includes a first drive 312, a second drive 313, and a hook member 314; the first drive 312 is provided with a first movable seat 315 that can move linearly along a first direction, and the second drive 313 is connected to the first movable seat 315; the second drive 313 is provided with a second movable seat 316 that can move linearly along a second direction, and the hook member 314 is mounted on the second movable seat 316; the first direction and the second direction are both horizontal and perpendicular to each other; the first movable seat 315 is also provided with a pusher, the hook member 314 is inserted into the reagent strip outlet 311, and pushes the reagent strip to move along the second direction to one side of the pusher; the pusher is driven to move the reagent strip to the injection position.

[0061] It should be noted that, in this embodiment of the application, a reagent tablet assembly 310 consisting of a first drive 312, a second drive 313, and a hook member 314 is provided to achieve precise gripping and efficient transfer of reagent tablets: the first drive 312 drives the first moving seat 315 to move along a first horizontal direction (e.g., the X direction), so that the hook member 314 is aligned with the reagent tablet outlet 311 of the target tablet compartment 308; then the second drive 313 drives the second moving seat 316 to move along a second horizontal direction perpendicular to it (e.g., the Y direction), so that the hook member 314 is inserted into the reagent tablet outlet 311 and hooks the reagent tablet; then the hook member 314 pulls the reagent tablet out of the tablet compartment 308 along the second direction and moves it to the side of the pusher fixed on the first moving seat 315; then the pusher is driven to push out along the first horizontal direction, pushing the reagent tablet to the sample inlet position of the inlet / outlet assembly 200. This structure utilizes two mutually perpendicular horizontal linear motions to collaboratively complete the "hooking-transfer-pushing" action. It features a compact layout, precise positioning, and reliable operation, effectively realizing fully automated and efficient transfer of reagent tablets from the tablet compartment 308 to the injection position, thereby improving the integration and operational stability of the entire machine.

[0062] As an optional implementation, the hook 314 is movably mounted on a rotating shaft provided on the second mounting base; the hook 314 includes a pushing part and a blocking part provided on both sides of the rotating shaft; when the hook 314 moves away from the reagent tablet outlet 311, the pushing part abuts against the reagent tablet, and the blocking part abuts against the limiting structure on the second mounting base to prevent the hook 314 from moving around the rotating shaft; when the hook 314 moves closer to the reagent tablet outlet 311, the pushing part can move around the rotating shaft, causing the limiting structure to separate from the blocking part; the weight of the blocking part is greater than that of the pushing part.

[0063] It should be noted that, in this embodiment, by setting a rotating shaft, a pushing part, and a blocking part on the hook 314, and utilizing its center of gravity distribution and the cooperation of the limiting structure, reliable gripping and non-destructive release of the reagent tablet are achieved: the hook 314 is movably mounted on the rotating shaft of the second moving seat 316, and its blocking part is heavier than the pushing part, so that the hook 314 maintains a stable posture with the pushing part facing upward and the blocking part facing downward in its natural state; when the hook 314 moves towards the reagent tablet outlet 311, the pushing part can rotate upward around the rotating shaft and smoothly insert under the reagent tablet; when it moves in the opposite direction, the pushing part abuts against the reagent tablet and drives it to move backward. At this time, the blocking part abuts against the limiting structure on the second moving seat 316, preventing the hook 314 from continuing to rotate, thereby firmly clamping the reagent tablet and pulling it out smoothly; after the transfer is completed, the pushing part directly acts on the reagent tablet during the pushing stage, and the hook 314 is no longer under force, avoiding interference. This design cleverly utilizes gravity and mechanical limits to achieve adaptive gripping and releasing, requiring no additional drive. It features a simple structure, reliable operation, and effectively ensures the stability and safety of the reagent strip transfer process.

[0064] The reagent compartment 308 contains several horizontally placed reagent tablets; the reagent tablets are arranged in sequence along the vertical direction.

[0065] As an optional implementation, the puncture positioning assembly 301 includes a horizontal drive, a vertical drive, and a puncture needle; the horizontal drive is provided with a third movable seat that can move linearly along a first direction, and the vertical drive is connected to the third movable seat; the vertical drive is provided with a fourth movable seat that can move linearly along a vertical direction, and the puncture needle is mounted on the fourth movable seat.

[0066] It should be noted that, in this embodiment, the puncture positioning component 301 adopts a two-dimensional motion structure combining horizontal and vertical drives: the horizontal drive moves the third moving seat along the first direction, allowing the puncture needle to switch positions between the puncture position 304 of the sampling tube and the sample dispensing position of the reagent strip; the vertical drive is mounted on the third moving seat, which drives the fourth moving seat to rise and fall vertically, thereby controlling the up and down movement of the puncture needle to complete the puncture and sampling of the sampling tube and the release of the sample. During operation, the puncture needle first moves to above the puncture position 304 under the action of the horizontal drive, and then the vertical drive presses down to puncture the sampling tube and draw up the sample; subsequently, the horizontal drive moves the puncture needle to the dispensing position, and the vertical drive again lowers the puncture needle, accurately dispensing the sample onto the reagent strip. This design achieves high-precision positioning and reliable operation of puncture and dispensing through two orthogonal linear drives, with a compact structure and rapid response, effectively supporting the stable operation of the fully automated detection process.

[0067] It should be noted that the linear drive components involved in the embodiments of this application, such as the first drive 312, the second drive 313, the vertical drive, and the horizontal drive, can all be electric lead screws or pneumatic linear drives, combined with a sliding guide rail structure to achieve linear drive. This is prior art and therefore not specifically limited. Those skilled in the art can make settings as needed.

[0068] Referring to FIG1, as an optional implementation, a waste tablet removal outlet 317 is provided on the operating surface of the front panel module 300; a window communicating with the waste tablet removal outlet is provided on the tablet loading and unloading assembly 200, the tablet loading and unloading assembly 200 is used to push the reagent tablet in the incubation assembly 210 into the window, and the reagent tablet moves to the waste tablet removal outlet 317 under the action of gravity.

[0069] It should be noted that this embodiment of the application constructs an automated reagent strip recovery mechanism by setting a waste strip outlet 317 in the front panel module 300 and connecting it to a window on the infeed / unload assembly 200: After the test is completed, the infeed / unload assembly 200 pushes the used reagent strips in the incubation assembly 210 to its own window, which is aligned with and connected to the waste strip outlet 317 of the front panel module 300; the reagent strips fall naturally under gravity and slide into the waste strip outlet 317 through the window, allowing the user to directly remove the waste reagent strips from the operating surface. This design requires no additional drive or complex structure, utilizing gravity to automatically export waste strips, which simplifies the overall structure, avoids the risk of cross-contamination, improves operational convenience and equipment sealing, and further perfects the fully automated closed loop from sample loading and testing to waste disposal.

[0070] Referring to FIG1, as an optional implementation, the front panel module 300 is provided with an operation panel 318 and a sampling tube scanning module.

[0071] It should be noted that, in this embodiment, an operation panel 318 and a sampling tube scanning module are integrated on the front panel module 300 to improve human-computer interaction efficiency and the intelligence level of the testing process. The operation panel 318 is used to receive user commands, display device status and reagent strip remaining information, and achieve intuitive and convenient operation control. The sampling tube scanning module is used to automatically read the barcode or QR code on the sampling tube when it is inserted, quickly identify sample information, test items and patient data, and link with the system backend to ensure the accuracy and traceability of the testing process. The two work together, which not only simplifies the operation steps and reduces the risk of human input errors, but also provides hardware support for realizing full-process information management and precision medicine.

[0072] Referring to Figures 1, 2 and 7, as an optional implementation, a sampling tube outlet 303 and a waste film outlet 317 are provided on the operating surface; both the sampling tube outlet 303 and the waste film outlet 317 are provided with a collection chamber 319.

[0073] It should be noted that, in this embodiment, a sampling tube outlet 303 and a waste strip removal outlet 317 are respectively provided on the operation surface of the front panel module 300, and collection chambers 319 are correspondingly configured behind them for automatically collecting waste generated during the testing process: after the sampling tube has been punctured and sampled, it is pushed to the sampling tube outlet 303 by the sample processing device 100 and falls into its corresponding collection chamber 319 for temporary storage; at the same time, the used reagent strips are pushed into the waste strip window by the strip loading and unloading assembly 200 and slide down into another collection chamber 319 below the waste strip removal outlet 317 under the influence of gravity. This design, by integrating two independent collection chambers 319, realizes the classification and closed centralized collection of sampling tubes and waste reagent strips, which not only avoids cross-contamination and biosafety risks, but also reduces the frequency of manual cleaning and improves the ease of operation, safety and overall automation level of the equipment in bedside, emergency and other scenarios.

[0074] Referring to Figure 8, this application embodiment provides a sample processing device, including: a turntable assembly, a puncture positioning assembly, and a sample unloading assembly disposed on a wall panel 10. The turntable assembly includes a turntable 11, which has a plurality of accommodating cavities 110 arranged circumferentially for accommodating sampling tubes 20. The puncture positioning assembly and the sample unloading assembly are respectively located on one side of the turntable 11. The turntable 11 rotates, driving the sampling tubes 20 to rotate to the positions corresponding to the puncture positioning assembly and the sample unloading assembly, respectively. The puncture positioning assembly punctures and samples the sampling tubes 20, and the sample unloading assembly unloads the sampling tubes 20 from the turntable 11.

[0075] Sampling tubes 20 are disposed within the receiving cavities 110 of the turntable 11. Multiple receiving cavities 110 are arranged circumferentially around the turntable 11, with one sampling tube 20 housed in each cavity. For example, the turntable 11 is circular. Multiple sampling tubes 20 are arranged in a circumferential ring around the turntable 11, with each sampling tube 20 arranged radially, its bottom pointing towards the center of the turntable 11. When the turntable 11 rotates, it drives the multiple sampling tubes 20 to rotate, achieving the effect of simultaneously mixing the multiple sampling tubes 20.

[0076] When the turntable 11 rotates to different positions, the same sampling tube 20 can be in different positions. The puncture positioning component and the sample unloading component are located on one side of the turntable 11 and correspond to the cavity opening 114 of the receiving cavity 110. When the sampling tube 20 rotates with the turntable 11 to the puncture position corresponding to the puncture positioning component, the puncture positioning component performs a puncture operation on the sampling tube 20; when the sampling tube 20 rotates to the sample unloading position corresponding to the sample unloading component, the sample unloading component unloads the sampling tube 20 from the turntable 11, thus completing one operation cycle.

[0077] The sample processing device provided in this application embodiment can realize sample injection, shaking, sampling and unloading. The device is equipped with a sample puncture position, which, together with the puncture positioning component, can perform functions such as puncture and sample aspiration. After the sample processing is completed, the sample can be unloaded.

[0078] The multiple accommodating cavities 110 on the turntable 11 allow for simultaneous operation on multiple sampling tubes 20. The turntable 11 drives the completion of all sample pretreatment processes (including sample injection, transport, rotation and mixing, puncture sampling, and sample removal), improving sample processing efficiency while meeting limited design space requirements. Furthermore, the entire device is structurally stable, ensuring reliable sample processing.

[0079] In some embodiments, as shown in FIG9, the sample processing device is fixedly mounted on the wall panel 10. The turntable assembly includes a motor 118 and a spindle 116. The spindle 116 passes through the wall panel 10 and is connected to the motor 118. The spindle 116 is also fixedly connected to the turntable 11. The motor 118 drives the turntable 11 to rotate through the spindle 116, so that the sampling tube 20 inside the turntable 11 rotates to different positions.

[0080] The turntable assembly also includes a first retaining ring 112 and a second retaining ring 113. The first retaining ring 112 and the second retaining ring 113 surround the outer peripheral wall of the turntable 11, which can block the cavity opening 114 of the accommodating cavity 110 of the turntable 11, and prevent the sampling tube 20 in the cavity opening 114 from sliding out of the accommodating cavity 110 under the action of gravity and centrifugal force.

[0081] The first retaining ring 112 is located on one side of the turntable 11 and is fixedly connected to the wall plate 10. The first retaining ring 112 is provided with a sample inlet 115, which is connected to the receiving cavity 110 on the turntable 11 located at the sample inlet position. The sampling tube 20 enters the receiving cavity 110 of the turntable 11 through the sample inlet 115. The second retaining ring 113 is located on the other side of the turntable 11 and is also fixed to the wall plate 10. A noise reduction component 117, such as noise reduction cotton, is also provided on the inner side of the second retaining ring 113, that is, between the second retaining ring 113 and the turntable 11, to reduce the noise generated by the collision between the sampling tube 20 and the second retaining ring 113 during the rotation and mixing process.

[0082] The puncture positioning assembly is located directly above the turntable 11. The puncture positioning assembly includes a mounting plate 130, a limiting block 132, and several elastic elements, such as springs. The springs are located between the mounting plate 130 and the limiting block 132, with one end of the spring fixed to the mounting plate 130 and the other end fixed to the limiting block 132.

[0083] Mounting plate 130 is fixed to wall panel 10. Mounting plate 130 extends to turntable 11 and forms a bent portion 131 on the side of turntable 11 away from wall panel 10. Mounting plate 130 has a puncture port 130a at the upper end of the outer peripheral wall of turntable 11. The puncture port 130a communicates with the cavity 114 of turntable 11. Limiting block 132 is located between the turntable 11 on the side away from wall panel 10 and the bent portion 131 of mounting plate 130. Limiting block 132 is connected to the bent portion 131 of mounting plate 130. A groove 111 is formed on the turntable 11 at the position of limiting block 132.

[0084] Due to the setting of the groove 111, the accommodating cavity 110 forms a semi-closed structure at the groove 111 position. Under natural conditions, under the compression force of the spring, the limiting block 132 and the groove 111 form a limiting space. This limiting space can be understood as the upper part of the accommodating cavity 110 near the outer peripheral wall of the turntable 11. The inner diameter of this limiting space in the direction perpendicular to the turntable 11 is smaller than the inner diameter in the direction parallel to the turntable 11. That is, the cross section of this limiting space forms a long strip in the radial direction of the turntable 11, which is adapted to the shape of the sampling tube 20. The limiting block 132 can restrict the sampling tube 20 within this limiting space.

[0085] When the sampling tube 20 rotates to the puncture position via the turntable 11, the spring located between the mounting plate 130 and the limiting block 132 will continuously generate a compressive force on the cap of the sampling tube 20, so that the sampling tube 20 is stable in the puncture position without shaking. The end face of the mounting plate 130 facing the accommodating cavity 110 forms a puncture port 130a, which is connected to the accommodating cavity 110, so that the puncture needle can be inserted into the sampling tube 20 in the accommodating cavity 110 through the puncture port 130a to perform puncture sampling operation.

[0086] The sample unloading assembly is located on the outer periphery of the turntable 11 and below the first retaining ring 112. The first retaining ring 112, the sample unloading assembly, and the second retaining ring 113 form a ring structure, which blocks the outer peripheral wall of the turntable 11 to prevent the sampling tube 20 inside the turntable 11 from sliding out of the turntable 11.

[0087] Specifically, referring to Figure 10, the sample unloading assembly is located at the bottom of the turntable 11, and includes a base 123. The base 123 is fixed to the wall panel 10, and a slide rail 121 and a motor 120 are fixed on the base 123. A slider is adapted on the slide rail 121, and the motor 120 is connected to the slider. The sliding door 122 is fixed on the slider or is integrally set with the slider. When the motor 120 rotates, it drives the sliding door 122 to move on the slide rail 121. The direction in which the sliding door 122 moves along the slide rail 121 is perpendicular to the surface of the turntable 11, and the sliding door 122 corresponds to the cavity opening 114 of the receiving cavity 110 at the bottom of the turntable 11.

[0088] In this way, when the sliding door 122 moves, it can block the opening 114 of the sample unloading cavity 110 of the turntable 11 or move away from the opening 114. In the non-unloading state, the sliding door 122 blocks the opening 114 of the cavity 110; when unloading is required, the sliding door 122 moves away from the opening 114 of the cavity 110. At this time, the opening 114 is unobstructed, and the sampling tube 20 in the opening 114 can slide out from the opening 114 by gravity. The area below this unloading position corresponds to the waste tube compartment. After the sampling tube 20 slides out, it naturally falls into the waste tube compartment.

[0089] On the other hand, the sample processing device is also equipped with several detection components. Depending on their location, the detection components include a sample injection detection component 141, a sample unloading detection component 142, and a sample positioning component 143.

[0090] The sample injection detection component 141 is fixed on the wall plate 10 and located at the upper end of the cavity 114 of the turntable 11 receiving cavity 110 closest to the sample injection port 115. It is used to detect whether the sampling tube 20 is injected into the correct position and whether the sampling tube 20 exceeds the specified length.

[0091] The sample unloading detection component 142 is mounted on the base 123 of the sample unloading component. The base 123 is fixed on the wall plate 10 and located at the upper end of the cavity 114 closest to the sample unloading position accommodating cavity 110. It is used to detect whether the sampling tube 20 has been unloaded.

[0092] The sample positioning component 143 is located at the upper end of the cavity opening 114 of the bottommost accommodating cavity 110 of the turntable 11 and is fixed on the wall plate 10 for accurate positioning of the turntable 11.

[0093] The detection component can be either an optocoupler 142b or a light sensor. For example, as shown in Figure 3, taking the sample unloading detection component 142 as an example, an optocoupler plate 142a is mounted on the base 123, and an optocoupler 142b is mounted on the optocoupler plate 142a. An optocoupler baffle 142c is connected to the moving door 122 of the sample unloading component, allowing the baffle 142c to move with the moving door 122. When the moving door 122 blocks the opening 114 of the receiving cavity 110 at the sample unloading position, the baffle 142b is located inside the optocoupler 142b. When the moving door 122 moves away, exposing the opening 114 of the receiving cavity 110 for sample unloading, the baffle 142c moves with the moving door 122 and is removed from the optocoupler 142b. At this time, the optocoupler 142b sends a signal to the controller, indicating that the sample unloading is complete. The detection of other components is performed similarly and will not be described further.

[0094] The sample processing device also includes a controller, which is electrically connected to the motor 118 of the detection component and the turntable component, the motor 120 of the sample unloading component, the puncture positioning component, etc., to automatically control, detect, and puncture the entire sample processing device, thereby automating the operation and improving operational efficiency and response accuracy.

[0095] In summary, the sample processing device provided in this application embodiment allows the sampling tube 20 to be inserted through the inlet 115 of the first retaining ring 112 during sample injection, passing through the cavity 114 of the turntable 11 to reach the receiving cavity 110. The turntable 11 is rotated by the motor 118 of the turntable assembly to mix the sample in the sampling tube 20. Since the unloading assembly, the first retaining ring 112, and the second retaining ring 113 form a ring structure surrounding the outer peripheral wall of the turntable 11, blocking the cavity 114, the sampling tube 20 will not slide down under the action of gravity and centrifugal force. The turntable 11 drives the sampling tube 20 to rotate and mix. After rotating several times, the sampling tube 20 reaches the puncture position. The limiting block 132 of the puncture positioning assembly stabilizes the sampling tube 20 in the set position. The puncture needle passes through the puncture port 130a on the mounting plate 130 to puncture the sampling tube 20 for sampling.

[0096] During sample unloading, motor 118 drives turntable 11 to rotate, and sampling tube 20 reaches the unloading position. Motor 120 of the unloading assembly drives slider and movable door 122 fixed on slider, causing movable door 122 to move away from turntable 11 along the direction perpendicular to the turntable 11. The cavity 114 at the unloading position is not blocked by movable door 122, and sampling tube 20 slides naturally from the receiving cavity 110 into the waste tube compartment by gravity. The sample processing device of this application can simultaneously perform sample injection, puncture, and shaking steps while unloading, greatly improving sample processing efficiency. The high integration is achieved through the stacked design of multiple receiving cavities 110 on turntable 11. The turntable assembly completes all processes of sample pretreatment (including sample injection, transportation, rotation and shaking, puncture sampling, and unloading) with a simplified structure and drive, while meeting the limited design space requirements.

[0097] The sample processing device provided in the above-described embodiments of this application realizes the functions of sample injection, transportation, mixing, buffering, and unloading of the sampling tube 20, resulting in a simpler process. Through the cooperation of the turntable 11 and the retaining ring, the requirements for sample injection from the outside and rotation of the test tube from the inside can be met, making the mechanism more flexible and space-saving. Simultaneously, motion stability is improved. Stable movement of the device is also achieved through precise motor 118 drive and limit block 132. The sample processing device provided in this embodiment of the application ensures stable operation while improving the reliability and efficiency of sample processing; in space-constrained situations, it realizes all functions of the entire sample processing process, significantly improving the performance of the immunoassay analyzer and meeting a wider range of application needs.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
