Description

Technical Field

[0001] This utility model relates to the field of biomedical technology, and in particular to an analyzer. Background Technology

[0002] Analyzers efficiently detect the concentration of various components in a sample by utilizing changes in the optical properties of substances during chemical reactions. With the increasing demands of the medical field, the performance requirements for analyzers are also rising, especially in terms of testing speed, accuracy, and automation. Therefore, many manufacturers are dedicated to developing high-speed, fully automated analyzers to meet the needs of clinical laboratories and research institutions.

[0003] Most high-speed analyzers currently on the market employ a dual-measurement system, where two measurement systems share a single reaction dish. To perform a series of operations, including sample dispensing, reagent addition, solution mixing, data acquisition, and automatic cleaning of the reaction vessel, these devices require continuous rotation of the reaction dish and the surrounding configuration of multiple components such as sample dispensing modules, reagent dispensing modules, mixing modules, photoelectric detection modules, and automatic cleaning modules. While this design improves automation to some extent, it also has some significant drawbacks.

[0004] However, traditional analyzers, due to the identical operating sequence of the inner and outer reaction discs, result in overly concentrated reagent and sample dispensing positions. This causes interference between component movement trajectories, reducing operational independence. Furthermore, a malfunction or maintenance requirement in one reagent dispensing subsystem can render the entire device inoperable, impacting testing efficiency. In addition, the overcrowded component layout of traditional analyzers makes cleaning and maintenance more complex and difficult, increasing both operating and maintenance costs.

[0005] The above information disclosed in the background art of this utility model is only used to understand the background of the concept of this utility model, and may include information that does not constitute prior art. Utility Model Content

[0006] Therefore, it is necessary to provide an analyzer to address the above problems.

[0007] This application provides an analyzer comprising:

[0008] frame;

[0009] A reaction disk is disposed on the frame and includes an inner ring and an outer ring of the reaction disk on which a reaction cup is loaded;

[0010] The outer ring of the reaction disk has an outer ring photoelectric acquisition working position, an outer ring reagent addition working position 1, an outer ring sample addition working position, an outer ring sample stirring and mixing working position, an outer ring reagent addition working position 2, an outer ring reagent stirring and mixing working position, and an outer ring reaction cup multi-stage cleaning working position.

[0011] The inner circle of the reaction disk has an inner circle photoelectric acquisition working position, an inner circle reagent addition working position 1, an inner circle sample addition working position, an inner circle sample stirring and mixing working position, an inner circle reagent addition working position 2, an inner circle reagent stirring and mixing working position, and an inner circle reaction cup multi-stage cleaning working position.

[0012] The first reagent needle assembly is disposed on the frame and is movable relative to the frame, and is used to transfer reagents to the reaction cups of the outer ring reagent addition station 1 and the outer ring reagent addition station 2.

[0013] The second reagent needle assembly is disposed on the frame and is movable relative to the frame, and is used to transfer reagents to the reaction cups of the inner ring reagent addition station 1 and the inner ring reagent addition station 2.

[0014] The line connecting the outer ring reagent-adding station 1 and the center of the reaction disk forms an angle greater than 90° with the line connecting the inner ring reagent-adding station 1 and the center of the reaction disk; the line connecting the outer ring reagent-adding station 2 and the center of the reaction disk forms an angle greater than 90° with the line connecting the inner ring reagent-adding station 2 and the center of the reaction disk; the first reagent needle assembly and the second reagent needle assembly are located on opposite sides of the reaction disk.

[0015] The aforementioned analyzer achieves at least the following beneficial effects: The angle between the line connecting the outer reagent addition station (position 1) and the center of the reaction plate, and the line connecting the inner reagent addition station (position 1) and the center of the reaction plate, is greater than 90°. This means the outer and inner reagent addition stations are relatively far apart, almost located on opposite sides of the reaction plate. Similarly, the angle between the line connecting the outer reagent addition station (position 2) and the center of the reaction plate, and the line connecting the inner reagent addition station (position 2) and the center of the reaction plate, is also greater than 90°. This means the outer and inner reagent addition stations are relatively far apart, almost located on opposite sides of the reaction plate. Therefore, the corresponding first and second reagent needle assemblies can also be placed on opposite sides of the reaction plate, avoiding overly crowded component layouts. This not only improves operational convenience but also reduces the risk of operational errors due to limited space. The dispersed workstation layout effectively avoids mutual interference between different operations, ensuring that sample dispensing, reagent addition, and photoelectric detection can be performed independently, thus improving the overall stability of the equipment. A well-designed layout makes cleaning and maintenance of the equipment easier, allows operators to more easily access each workstation, reduces maintenance costs, and extends the lifespan of the equipment.

[0016] In some embodiments, the reaction disk is arranged with A multiplied by B plus / minus 1 reaction cup around its perimeter, where A and B are both natural numbers, and A is greater than B; the cup numbers of the photoelectric acquisition workstation, sample addition workstation, sample mixing workstation, reagent mixing workstation, and multi-stage cleaning workstation corresponding to the inner and outer rings of the reaction disk differ by C, where C is a natural number; the difference between the first reagent addition workstation on the inner and outer rings of the reaction disk is D, and the difference between the second reagent addition workstation on the inner and outer rings of the reaction disk is D, where D equals A multiplied by E minus / plus C, and E is a natural number less than B.

[0017] In some embodiments, 246 reaction cups are evenly arranged circumferentially on both the outer and inner rings of the reaction disk, and 246 cup positions are sequentially numbered circumferentially on the reaction disk. The first reagent-adding position on the outer ring is located at cup position 63, so the first reagent-adding position on the inner ring is located at cup position 207. The second reagent-adding position on the outer ring is located at cup position 82, so the second reagent-adding position on the inner ring is located at cup position 226. The first reagent-adding position on the outer ring is located at cup position 63, and the first reagent-adding position on the inner ring is located at cup position 207, ensuring that the angle between them is greater than 90°. The second reagent-adding position on the outer ring is located at cup position 82, and the second reagent-adding position on the inner ring is located at cup position 226, similarly ensuring that the angle between them is greater than 90°, achieving a staggered arrangement. The rational distribution of outer and inner working positions avoids mutual interference between operations. Parallel operations at different working positions are possible, improving overall testing efficiency. Clear numbering and distribution make maintenance and cleaning more convenient for operators.

The first reagent needle assembly includes a first inner reagent needle and a first outer reagent needle. The outer reagent needle is disposed on the frame and is movable relative to the frame, and is used to draw the first reagent from the reagent bottle on the outer ring and transfer it to the reaction cup at the first reagent addition station on the outer ring. The inner reagent needle is disposed on the frame and is movable relative to the frame, and is used to draw the second reagent from the reagent bottle on the inner ring and transfer it to the reaction cup at the second reagent addition station on the outer ring.

The inner reagent needle is disposed on the frame and is movable relative to the frame, and is used to draw the first reagent from the reagent bottle on the inner ring and transfer it to the reaction cup at the first reagent loading station on the outer ring.

[0026] In some embodiments, the movement trajectory of the first inner reagent needle does not intersect with that of the first outer reagent needle. The inner and outer rings of the first reagent tray can rotate independently, a design that makes reagent acquisition and transfer more efficient. The rotation of the reagent tray can be flexibly adjusted as needed to quickly locate the required reagent bottle, reducing waiting time and improving overall work efficiency. Due to the independent rotation design of the inner and outer rings, the rotation speed and direction can be better controlled during operation, reducing vibration and instability caused by improper rotation, thereby improving the overall stability and reliability of the equipment. The first reagent needle assembly includes a first inner reagent needle and a first outer reagent needle, used to draw reagents from the inner and outer rings of the first reagent tray, respectively. This dual-needle design not only improves the reagent transfer speed but also allows for the extraction of reagents from different locations simultaneously, further enhancing the equipment's processing capacity. The movement trajectories of the first inner reagent needle and the first outer reagent needle do not intersect, avoiding interference and collisions during movement that could cause damage or jamming. This design also ensures no cross-contamination occurs during reagent transfer, a crucial feature for the analyzer as cross-contamination can lead to errors in analytical results and affect experimental accuracy. Furthermore, this design allows for the simultaneous use of multiple reagents in the same experiment, accommodating diverse experimental needs. This flexibility enables the analyzer to be widely applied in various biochemical detection scenarios, meeting diverse experimental requirements. In summary, this implementation method, through optimized structural design of the first reagent tray assembly, further improves the analyzer's efficiency, accuracy, and ease of operation, providing users with a superior analytical experience.

[0027] In some embodiments, the analyzer further includes a second reagent tray assembly disposed on the frame. The second reagent tray assembly includes an inner ring and an outer ring containing reagent bottles. The outer ring is fitted over the inner ring, and the inner and outer rings are rotatable independently. The reagent bottle on the outer ring contains a first reagent, and the reagent bottle on the inner ring contains a second reagent. The second reagent needle assembly includes a second inner reagent needle and a second outer reagent needle. The second outer reagent needle is disposed on the frame and movable relative to the frame, and is used to draw the first reagent from the reagent bottle on the outer ring and transfer it to the reaction cup at the first reagent addition station on the inner ring. The second inner reagent needle is disposed on the frame and movable relative to the frame, and is used to draw the second reagent from the reagent bottle on the inner ring and transfer it to the reaction cup at the second reagent addition station on the inner ring. In other embodiments, the analyzer further includes a second reagent tray assembly disposed on the frame. The second reagent tray assembly includes a second reagent tray inner ring and a second reagent tray outer ring containing reagent bottles. The second reagent tray outer ring is fitted onto the second reagent tray inner ring, and the second reagent tray inner ring and the second reagent tray outer ring are rotatable independently of each other. The reagent bottle in the second reagent tray outer ring contains a second reagent, and the reagent bottle in the second reagent tray inner ring contains a first reagent. The second reagent needle assembly includes a second inner reagent needle and a second outer reagent needle. The second outer reagent needle is disposed on the frame and is movable relative to the frame, and is used to draw the second reagent from the reagent bottle in the second reagent tray outer ring and transfer it to the reaction cup in the reaction cup in the reaction tray inner ring plus reagent working position two. The second inner reagent needle is disposed on the frame and is movable relative to the frame, and is used to draw the first reagent from the reagent bottle in the second reagent tray inner ring and transfer it to the reaction cup in the reaction tray inner ring plus reagent working position one.

[0028] In some embodiments, the movement trajectory of the second inner reagent needle does not intersect with that of the second outer reagent needle. The inner and outer rings of the second reagent tray can rotate independently, a design that makes reagent acquisition and transfer more efficient. The rotation of the reagent tray can be flexibly adjusted as needed to quickly locate the required reagent bottle, reducing waiting time and improving overall work efficiency. Due to the independent rotation design of the inner and outer rings, the rotation speed and direction can be better controlled during operation, reducing vibration and instability caused by improper rotation, thereby improving the overall stability and reliability of the equipment. The second reagent needle assembly includes a second inner reagent needle and a second outer reagent needle, used to draw reagents from the inner and outer rings of the second reagent tray, respectively. This dual-needle design not only improves the reagent transfer speed but also allows for the extraction of reagents from different locations simultaneously, further enhancing the equipment's processing capacity. The non-intersecting movement trajectories of the second inner and outer reagent needles prevent interference and collisions during movement, avoiding damage or jamming. It also ensures that cross-contamination does not occur during reagent transfer, a design particularly important for analyzers, as cross-contamination can lead to errors in analytical results and affect experimental accuracy. This design also allows for the simultaneous use of multiple reagents in the same experiment, adapting to different experimental needs. This flexibility enables the analyzer to be widely used in various biochemical detection scenarios, meeting diverse experimental requirements. In summary, this implementation method, through optimizing the structural design of the second reagent tray assembly, further improves the analyzer's efficiency, accuracy, and ease of operation, providing users with a superior analytical experience.

[0029] In some embodiments, the first reagent tray assembly and the second reagent tray assembly are spaced apart and located on opposite sides of the reaction tray. By distributing the first and second reagent tray assemblies on opposite sides of the reaction tray, the space layout of the equipment is fully utilized, crowding between components is avoided, and the overall design rationality is improved. The spaced-out design effectively avoids interference between different reagent tray assemblies, reduces the risk of cross-contamination during operation, and ensures the accuracy and reliability of experimental results. This layout allows operators easier access to each reagent tray when retrieving and transferring reagents, reducing movement distances during operation and improving work efficiency. The spaced-out arrangement of the components makes maintenance and cleaning easier, reducing cleaning difficulties caused by limited space, and improving the equipment's lifespan and hygiene level.

[0030] In some embodiments, the first and second reagent needle assemblies can be mounted to the frame via linear guides and / or a rotating rocker arm to enable movement of the first and second reagent needle assemblies relative to the frame. The use of linear guides and rotating rocker arms allows for high-precision movement of the reagent needle assemblies. This precise control is crucial for reagent extraction and transfer processes, ensuring accurate positioning and effective extraction, thereby improving experimental reliability. This design not only supports linear movement of the reagent needles but also enables multi-dimensional movement, expanding the device's functionality. For example, the linear guides allow the reagent needle assemblies to move smoothly along a set track, while the rotating rocker arm allows operation at different angles. This flexibility allows the device to adapt to different types of reagent bottle and reaction cup layouts, meeting diverse experimental needs. Furthermore, the rotating rocker arm allows the reagent needles to operate at different angles, adapting to more complex experimental requirements.

[0031] In some embodiments, the rotating rocker arm includes a first rocker arm assembly and a second rocker arm assembly mounted on the frame with independent motion trajectories. The first rocker arm assembly is located between the reaction disk and the first reagent disk assembly, and the second rocker arm assembly is located between the reaction disk and the second reagent disk assembly. The first rocker arm assembly includes a first inner rocker arm and a first outer rocker arm mounted on the frame with independent motion trajectories. The first inner rocker arm is connected to the first inner reagent needle and drives the first inner reagent needle to move. The first outer rocker arm is connected to the first outer reagent needle and drives the first outer reagent needle to move. The second rocker arm assembly includes a second inner rocker arm and a second outer rocker arm mounted on the frame with independent motion trajectories. The second inner rocker arm is connected to the second inner reagent needle and drives the second inner reagent needle to move. The second outer rocker arm is connected to the second outer reagent needle and drives the second outer reagent needle to move. The independent design of the first and second rocker arm assemblies ensures that the movements of the two reagent needles do not interfere with each other during operation. This independence allows the device to process different reagents simultaneously, improving experimental efficiency and flexibility. The first inner rocker arm and the first outer rocker arm are each connected to a corresponding reagent needle, enabling precise control of the needle's movement trajectory. This precise control is crucial for ensuring accurate reagent extraction and transfer, reducing operational errors. By separately configuring the first inner rocker arm, the first outer rocker arm, the second inner rocker arm, and the second outer rocker arm, the design more effectively utilizes rack space, resulting in a more compact structure that adapts to the needs of different laboratory environments. Simultaneously, this design reduces the overall size of the equipment, facilitating operation and maintenance.

[0032] In some embodiments, the inner and outer rings of the reaction disk can rotate independently. The inner and outer rings employ independent rotational drives, allowing for different test speeds and cycle sequences to be set according to actual needs. This flexibility enables the device to adapt to various experimental requirements, improving testing efficiency and accuracy. The inner and outer rings can be configured to rotate in opposite directions, allowing operation within the same cycle sequence. This effectively coordinates the work of the inner and outer rings, ensuring consistent reaction conditions for different reagents and samples during the experiment, thereby improving experimental reliability. Due to the independent rotational drives of the inner and outer rings, the reagent stirring cup position on the inner ring can be adjacent to the sample stirring cup position on the outer ring, and vice versa. This design makes the stirring and mixing of reagents and samples more efficient, better promoting the reaction and improving reaction uniformity and speed.

[0033] In some embodiments, the analyzer further includes a photometer, a cleaning mechanism, a sample stirring assembly, and a reagent stirring assembly disposed on the rack and distributed around the reaction plate; the photometer is capable of performing photoelectric data acquisition on the reaction cups at the outer and inner photoelectric acquisition work positions to obtain test reaction data within the reaction cups; the cleaning mechanism is capable of performing multi-stage cleaning on the reaction cups at the outer and inner multi-stage cleaning work positions; the sample stirring assembly is capable of performing sample stirring and mixing on the reaction cups at the outer and inner sample stirring and mixing work positions to mix the first reagent and sample in the reaction cups to form a reaction solution; the reagent stirring assembly is capable of performing reagent stirring and mixing on the reaction cups at the outer and inner reagent stirring and mixing work positions to mix the second reagent and reaction solution in the reaction cups.

[0034] In some embodiments, the analyzer further includes a track and a sample needle assembly. The track is mounted on the frame, and the sample needle assembly can be mounted to the frame via a linear guide and / or a rotating rocker arm to allow movement of the sample needle assembly relative to the frame. The sample needle assembly is positioned between the track and the reaction disk, and includes a first sample needle and a second sample needle mounted on the frame with independent movement trajectories. The first sample needle is used to pick up the sample on the track and transfer it to a reaction cup with a sample working position on the inner ring of the reaction disk, while the second sample needle is used to pick up the sample on the track and transfer it to a reaction cup with a sample working position on the outer ring. The sample needle assembly can be mounted to the frame via a linear guide and / or a rotating rocker arm, thereby enabling flexible movement of the sample needle assembly relative to the frame. This design improves the efficiency of sample transfer, allowing samples to be quickly transferred from the track to the designated working position on the reaction disk. The independent movement trajectories of the first and second sample needles ensure that no collisions or interference occur during sample transfer. This design improves the safety and stability of the equipment and avoids potential errors during sample transfer. The first sample needle transfers the sample from the track to the reaction cup with the inner sample working position, while the second sample needle transfers the sample to the reaction cup with the outer sample working position. This division of labor allows the analyzer to process multiple samples simultaneously, improving the parallel processing capability and overall efficiency of the experiment. The placement of the sample needle assembly between the track and the reaction plate effectively utilizes the equipment space, reducing the equipment's footprint. This compact layout makes the equipment more flexible and easier to operate in a laboratory environment. Through the integration of the track and sample needle assembly, the analyzer achieves a higher level of automation, reducing the need for manual intervention. This automation not only improves work efficiency but also reduces the risk of human error, ensuring the reliability of experimental results. Attached Figure Description

[0040] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0041] Please see Figure 1 and Figure 2In some embodiments, the present invention provides an analyzer 10, which includes a frame 100, a reaction disk 300, a first reagent needle assembly 610, and a second reagent needle assembly 620. The reaction disk 300 is located on the frame 100 and includes an inner ring 310 and an outer ring 320 containing reaction cups. The outer ring 320 has a rotation path with an outer ring photoelectric acquisition station 1, an outer ring reagent addition station 2, an outer ring sample addition station 3, an outer ring sample mixing station 4, an outer ring reagent addition station 5, an outer ring reagent mixing station 6, and an outer ring multi-stage cleaning station for the reaction cups. The inner ring 310 has a rotation path with an inner ring photoelectric acquisition station 11, an inner ring reagent addition station 12, an inner ring sample addition station 13, an inner ring sample mixing station 14, an inner ring reagent addition station 15, an inner ring reagent mixing station 16, and an inner ring multi-stage cleaning station for the reaction cups. The first reagent needle assembly 610 is located on the frame 100 and can move relative to the frame 100, and is used to insert the first reagent needle assembly 610 into the reaction cup. A reagent is transferred to the reaction cups at the outer ring reagent addition station 1 (2) and the outer ring reagent addition station 2 (5). A second reagent needle assembly 620 is disposed on the frame 100 and is movable relative to the frame 100, used to transfer the second reagent to the reaction cups at the inner ring reagent addition station 12 and the inner ring reagent addition station 2 (15). The angle between the line connecting the outer ring reagent addition station 1 (2) and the center of the reaction disk 300 and the line connecting the inner ring reagent addition station 12 and the center of the reaction disk 300 is greater than 90°. The angle between the line connecting the outer ring reagent addition station 2 (5) and the center of the reaction disk 300 and the line connecting the inner ring reagent addition station 2 (15) and the center of the reaction disk 300 is greater than 90°. The first reagent needle assembly 610 and the second reagent needle assembly 620 are located on opposite sides of the reaction disk 300.

[0042] The analyzer 10 described above can achieve at least the following beneficial effects: the angle between the line connecting the outer ring reagent addition station 1 2 and the center of the reaction disk 300 and the line connecting the inner ring reagent addition station 12 and the center of the reaction disk 300 is greater than 90°, that is, the outer ring reagent addition station 1 2 and the inner ring reagent addition station 12 are far apart, almost located on both sides of the reaction disk 300; the angle between the line connecting the outer ring reagent addition station 2 5 and the center of the reaction disk 300 and the line connecting the inner ring reagent addition station 2 15 and the center of the reaction disk 300 is greater than 90°, that is, the outer ring reagent addition station 2 5 and the inner ring reagent addition station 2 15 are far apart, almost located on both sides of the reaction disk 300. Therefore, the corresponding first reagent needle assembly 610 and second reagent needle assembly 620 can also be set on both sides of the reaction disk 300, which can avoid the component layout being too crowded, not only improving the convenience of operation, but also reducing the risk of operational errors due to narrow space. The distributed workstation layout effectively avoids mutual interference between different operations, ensuring that operations such as sample dispensing, reagent addition, and photoelectric detection can be performed independently, thus improving the overall stability of the equipment. The rational layout also simplifies equipment cleaning and maintenance, making it easier for operators to access each workstation, reducing maintenance costs, and extending the equipment's lifespan.

[0043] In some embodiments, the reaction disk is arranged with A multiplied by B plus / minus 1 reaction cup around its perimeter, where A and B are both natural numbers, and A is greater than B; the cup numbers of the photoelectric acquisition workstation, sample addition workstation, sample mixing workstation, reagent mixing workstation, and multi-stage cleaning workstation corresponding to the inner and outer rings of the reaction disk differ by C, where C is a natural number; the difference between the first reagent addition workstation on the inner and outer rings of the reaction disk is D, and the difference between the second reagent addition workstation on the inner and outer rings of the reaction disk is D, where D equals A multiplied by E minus / plus C, and E is a natural number less than B.

[0044] like Figure 1 and Figure 2As shown, in some embodiments, 246 reaction cups are evenly arranged circumferentially on both the outer ring 320 and the inner ring 310 of the reaction disk, and 246 cup positions are sequentially numbered circumferentially on the reaction disk 300; the outer ring reagent addition position 1 2 is located at cup position 63, so the inner ring reagent addition position 1 12 is located at cup position 207; the outer ring reagent addition position 2 5 is located at cup position 82, so the inner ring reagent addition position 2 15 is located at cup position 226. The outer ring reagent addition position 1 2 being located at cup position 63 and the inner ring reagent addition position 1 12 being located at cup position 207 ensures that the angle between them is greater than 90°. The outer ring reagent dispensing station 2, position 5, is located at cup position 82, while the inner ring reagent dispensing station 2, position 15, is located at cup position 226. Similarly, the angle between these stations and the outer ring reagent dispensing station 2, position 5, is ensured to be greater than 90°, achieving a staggered layout. This rational distribution of the outer and inner ring stations avoids mutual interference between operations. Parallel operations at different stations are possible, improving overall testing efficiency. Clear numbering and distribution make maintenance and cleaning more convenient for operators.

[0045] like Figure 1 and Figure 2 As shown, in some embodiments, the outer ring sample loading station 3 is located at cup position 166, and the inner ring sample loading station 13 is located at cup position 163. The outer ring sample mixing station 4 is located at cup position 167, and the inner ring sample mixing station 14 is located at cup position 114.

[0066] like Figure 1 and Figure 2 As shown, in some embodiments, the first reagent tray assembly 510 and the second reagent tray assembly 520 are spaced apart and located on opposite sides of the reaction tray 300. By distributing the first reagent tray assembly 510 and the second reagent tray assembly 520 on opposite sides of the reaction tray 300, the space layout of the equipment is fully utilized, crowding between components is avoided, and the overall design rationality is improved. The spaced-out design effectively avoids interference between different reagent tray assemblies, reduces the risk of cross-contamination during operation, and ensures the accuracy and reliability of experimental results. This layout allows operators to more easily access each reagent tray when handling and transferring reagents, reducing the distance traveled during operation and improving work efficiency. The spaced-out arrangement of the components makes the equipment easier to maintain and clean, reducing the cleaning difficulty caused by limited space, and improving the service life and hygiene level of the equipment.

[0067] like Figure 1 and Figure 2 As shown, in some embodiments, the first reagent needle assembly 610 and the second reagent needle assembly 620 can be mounted to the frame 100 via linear guides and / or a rotating rocker arm to enable movement of the first reagent needle assembly 610 and the second reagent needle assembly 620 relative to the frame 100. The use of linear guides and rotating rocker arms allows for high-precision movement of the reagent needle assemblies. This precise control is crucial for reagent extraction and transfer processes, ensuring accurate positioning and effective extraction of reagents, thereby improving experimental reliability. This design not only supports linear movement of the reagent needles but also enables multi-dimensional movement, expanding the functionality of the device. For example, the linear guides allow the reagent needle assemblies to move smoothly along a set track, while the rotating rocker arm allows the reagent needle assemblies to operate at different angles. This flexibility allows the device to adapt to different types of reagent bottle and reaction cup layouts, meeting diverse experimental needs. Furthermore, the rotating rocker arm allows the reagent needles to operate at different angles, thus adapting to more complex experimental requirements.

[0068] like Figure 1 and Figure 2As shown, in some embodiments, the rotating rocker arm includes a first rocker arm assembly 710 and a second rocker arm assembly 720 disposed on the frame 100 with independent motion trajectories. The first rocker arm assembly 710 is disposed between the reaction disk 300 and the first reagent disk assembly 510, and the second rocker arm assembly 720 is disposed between the reaction disk 300 and the second reagent disk assembly 520. The first rocker arm assembly 710 includes a first inner rocker arm 711 and a first outer rocker arm 712 disposed on the frame 100 with independent motion trajectories. The first inner rocker arm 711 and the first outer rocker arm 712 are connected in series. A needle 611 is connected to and used to move the first inner reagent needle 611. A first outer rocker arm 712 is connected to and used to move the first outer reagent needle 612. The second rocker arm assembly 720 includes a second inner rocker arm 721 and a second outer rocker arm 722 disposed on the frame 100, with independent movement trajectories. The second inner rocker arm 721 is connected to and used to move the second inner reagent needle 621, and the second outer rocker arm 722 is connected to and used to move the second outer reagent needle 622. The independent design of the first rocker arm assembly 710 and the second rocker arm assembly 720 ensures that the movements of the two reagent needles do not interfere with each other during operation. This independence allows the device to process different reagents simultaneously, improving experimental efficiency and flexibility. The first inner rocker arm 711 and the first outer rocker arm 712 are respectively connected to the corresponding reagent needles, enabling precise control of the reagent needle's movement trajectory. This precise control is crucial for ensuring accurate reagent extraction and transfer, reducing operational errors. By separately configuring the first inner rocker arm 711, the first outer rocker arm 712, the second inner rocker arm 721, and the second outer rocker arm 722, the design can more effectively utilize the space of the rack 100, making the equipment more compact in structure and adaptable to the needs of different laboratory environments. At the same time, this design can also reduce the overall size of the equipment, making operation and maintenance easier.

[0069] like Figure 1 and Figure 2As shown, in some embodiments, the inner ring 310 and the outer ring 320 of the reaction disk can rotate independently. The inner and outer rings employ independent rotational drives, allowing for different test speeds and cycle sequences to be set according to actual needs. This flexibility enables the device to adapt to various experimental requirements, improving testing efficiency and accuracy. The inner and outer rings can be configured to rotate in opposite directions, allowing operation within the same cycle sequence. This effectively coordinates the work of the inner and outer rings, ensuring consistent reaction conditions for different reagents and samples during the experiment, thereby improving experimental reliability. Due to the independent rotational drives of the inner and outer rings, the reagent stirring cup position of the inner ring can be adjacent to the sample stirring cup position of the outer ring, and vice versa. This design makes stirring and mixing between reagents and samples more efficient, better promoting the reaction and improving reaction uniformity and speed.

[0070] like Figure 1 and Figure 2 As shown, in some embodiments, the analyzer 10 further includes a photometer 210, a cleaning mechanism 220, a sample stirring assembly 230, and a reagent stirring assembly 240 disposed on the frame 100 and distributed around the reaction plate 300; the photometer 210 is capable of performing photoelectric data acquisition on the reaction cups at the outer ring photoelectric acquisition working position 1 and the inner ring photoelectric acquisition working position 11 to obtain test reaction data in the reaction cups; the cleaning mechanism 220 is capable of performing multi-stage cleaning of the outer ring reaction cups at the multi-stage cleaning working position 7 and the inner ring reaction plate 300. The reaction cups on the multi-stage cleaning workstation 17 undergo multi-stage cleaning; the sample stirring assembly 230 can perform sample stirring and mixing actions on the reaction cups on the outer ring sample stirring and mixing workstation 4 and the inner ring sample stirring and mixing workstation 144, mixing the first reagent and sample in the reaction cups to form a reaction solution; the reagent stirring assembly 240 can perform reagent stirring and mixing actions on the reaction cups on the outer ring reagent stirring and mixing workstation 6 and the inner ring reagent stirring and mixing workstation 16, mixing the second reagent and reaction solution in the reaction cups.

[0071] like Figure 1 and Figure 2As shown, in some embodiments, the analyzer 10 further includes a track and a sample needle assembly 400. The track is disposed on the frame 100, and the sample needle assembly 400 can be mounted to the frame 100 via a linear guide rail and / or a rotating rocker arm to achieve movement of the sample needle assembly 400 relative to the frame 100. The sample needle assembly 400 is disposed between the track and the reaction disk 300. The sample needle assembly 400 includes a first sample needle 410 and a second sample needle 420 disposed on the frame 100 with independent movement trajectories. The first sample needle 410 is used to pick up the sample on the track and transfer it to the reaction cup in the inner ring 310 of the reaction disk plus the sample working position. The second sample needle 420 is used to pick up the sample on the track and transfer it to the reaction cup in the outer ring plus the sample working position 3. The sample needle assembly 400 can be mounted to the frame 100 via a linear guide rail and / or a rotating rocker arm, thereby achieving flexible movement of the sample needle assembly 400 relative to the frame 100. This design improves sample transfer efficiency, enabling samples to be quickly transferred from the track to the designated working position on the reaction plate 300. The movement trajectories of the first sample needle 410 and the second sample needle 420 do not interfere with each other, ensuring no collisions or interference occur during sample transfer. This design enhances the safety and stability of the device, avoiding potential errors during sample transfer. The first sample needle 410 is responsible for transferring the sample from the track to the reaction cup with the inner ring plus sample working position 13, while the second sample needle 420 transfers the sample to the reaction cup with the outer ring plus sample working position 3. This division of labor allows the analyzer 10 to process multiple samples simultaneously, improving the parallel processing capability and overall efficiency of the experiment. The design of the sample needle assembly 400 located between the track and the reaction plate 300 effectively utilizes the device space, reducing the device's footprint. This compact layout makes the device more flexible and easier to operate in a laboratory environment. Through the integration of the track and the sample needle assembly 400, the analyzer 10 achieves a higher level of automation, reducing the need for manual intervention. This automation not only improves work efficiency but also reduces the risk of human error, ensuring the reliability of experimental results.
