Description

Technical Field

[0001] The present invention relates to the field of biomedical technology, in particular to an analyzer. Background Art

[0002] Analyzers can efficiently detect the concentration of various components in samples by utilizing the changes in the optical properties of substances during chemical reactions. As medical needs continue to grow, the performance requirements for analyzers are also increasing, especially in terms of test speed, accuracy, and automation. Therefore, many manufacturers are committed to developing high-speed fully automatic analyzers to meet the needs of clinical laboratories and research institutions.

[0003] Most of the high-speed analyzers currently available on the market use a dual measurement system solution, that is, two measurement systems share a reaction disk. In order to complete a series of operations such as sample filling, reagent addition, solution stirring, data collection, and automatic cleaning of the reaction container, these devices need to continuously rotate the reaction disk and configure multiple components around it, such as sample dispensing module, reagent dispensing module, stirring and mixing module, photoelectric detection module, and automatic cleaning module. Although this design improves the automation of the test to a certain extent, it also has some significant defects.

[0004] However, the traditional analyzer has the same working sequence of the inner and outer reaction disks, which leads to the over-centralization of the reagent and sample adding positions, causing interference in the motion trajectories between components, reducing the independence of operation, and when a reagent dispensing subsystem fails or requires maintenance, the entire device may not work properly, affecting the test efficiency. In addition, the traditional analyzer has an overly crowded component layout, making cleaning and maintenance operations more complicated and difficult, increasing the use and maintenance costs of the equipment.

[0005] BACKGROUND OF THE INVENTION The above information disclosed is only for understanding the background of the inventive concept and may contain information that does not constitute the prior art. Summary of the invention

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

[0007] The present application provides an analyzer, comprising:

[0008] frame;

[0009] A reaction disk, arranged on the frame and comprising an inner ring of the reaction disk loaded with reaction cups and an outer ring of the reaction disk;

[0010] The outer ring of the reaction disk has an outer ring photoelectric collection workstation, an outer ring reagent adding workstation No. 1, an outer ring sample adding workstation, an outer ring sample stirring and mixing workstation, an outer ring reagent adding workstation No. 2, an outer ring reagent stirring and mixing workstation and an outer ring reaction cup multi-stage cleaning workstation on the rotation track of the outer ring;

[0011] The rotation track of the inner circle of the reaction disk is provided with an inner circle photoelectric collection work station, an inner circle reagent adding work station No. 1, an inner circle sample adding work station, an inner circle sample stirring and mixing work station, an inner circle reagent adding work station No. 2, an inner circle reagent stirring and mixing work station and an inner circle reaction cup multi-stage cleaning work station;

[0012] A first reagent needle assembly, which is disposed on the frame and can move relative to the frame, and is used to transfer the reagent to the reaction cups at the outer ring reagent adding work position No. 1 and the outer ring reagent adding work position No. 2;

[0013] A second reagent needle assembly, which is disposed on the frame and can move relative to the frame, and is used to transfer the reagent to the reaction cups at the inner circle reagent adding work position No. 1 and the inner circle reagent adding work position No. 2;

[0014] Among them, the angle between the line connecting the outer ring plus reagent No. 1 working position and the center of the reaction disk and the line connecting the inner ring plus reagent No. 1 working position and the center of the reaction disk is greater than 90°; the angle between the line connecting the outer ring plus reagent No. 2 working position and the center of the reaction disk and the line connecting the inner ring plus reagent No. 2 working position and the center of the reaction disk is greater than 90°; the first reagent needle assembly and the second reagent needle assembly are located on both sides of the reaction disk.

[0015] The above analyzer can at least achieve the following beneficial effects: the angle between the line connecting the outer ring reagent No. 1 workstation and the center of the reaction disk and the line connecting the inner ring reagent No. 1 workstation and the center of the reaction disk is greater than 90°, that is, the positions of the outer ring reagent No. 1 workstation and the inner ring reagent No. 1 workstation are far away and almost located on both sides of the reaction disk; the angle between the line connecting the outer ring reagent No. 2 workstation and the center of the reaction disk and the line connecting the inner ring reagent No. 2 workstation and the center of the reaction disk is greater than 90°, that is, the positions of the outer ring reagent No. 2 workstation and the inner ring reagent No. 2 workstation are far away and almost located on both sides of the reaction disk, so the corresponding first reagent needle assembly and the second reagent needle assembly can also be arranged on both sides of the reaction disk, which can avoid the component layout from being too crowded, not only improving the convenience of operation, but also reducing the risk of operational errors caused by narrow space. The dispersed workstation layout effectively avoids mutual interference between different operations, ensuring that operations such as sample filling, reagent addition and photoelectric detection can be performed independently, improving the overall stability of the equipment. Reasonable layout makes cleaning and maintenance of equipment easier, and operators can more easily access each workstation, which reduces maintenance costs and increases the service life of equipment.

[0016] In some embodiments, one circle of the reaction disk is provided with A times B plus / minus 1 reaction cup, wherein A and B are both natural numbers, and A is greater than B; the position numbers of the photoelectric collection workstation, sample addition workstation, sample stirring and mixing workstation, reagent stirring and mixing workstation, and reaction cup multi-stage cleaning workstation corresponding to the inner and outer circles of the reaction disk differ by C, and C is a natural number; the difference between the reagent addition No. 1 workstation of the inner and outer circles of the reaction disk is D, and the difference between the reagent addition No. 2 workstation of the inner and outer circles of the reaction disk is D, and D is equal to A times E minus / plus C, and E is a natural number less than B.

The reasonable distribution of the outer and inner working positions avoids mutual interference between operations. Parallel operations can be performed at different working positions, which improves the overall efficiency of the test. Clear numbering and distribution make it more convenient for operators to maintain and clean.

[0018] In some of the embodiments, the outer circle photoelectric collection working position is located between cup position No. 5 and cup position No. 6, and the inner circle photoelectric collection working position is located between cup position No. 2 and cup position No. 3.

[0022] In some embodiments, the outer circle reagent stirring and mixing work position is located at cup position No. 33, and the inner circle reagent stirring and mixing work position is located at cup position No. 30.

[0023] In some embodiments, the outer circle reaction cup multi-stage cleaning workstations are located at cup positions 4 to 13, and the inner circle reaction cup multi-stage cleaning workstations are located at cup positions 1 to 10.

[0024] In some of the embodiments, the outer circle photoelectric collection working position is located between cup position No. 5 and cup position No. 6, and the inner circle photoelectric collection working position is located between cup position No. 2 and cup position No. 3.

[0025] In some embodiments, the analyzer also includes a first reagent tray assembly disposed on the frame, the first reagent tray assembly including a first reagent tray inner ring loaded with reagent bottles and a first reagent tray outer ring, the first reagent tray outer ring is sleeved on the first reagent tray inner ring, and the first reagent tray inner ring and the first reagent tray outer ring can rotate independently of each other, the reagent bottle of the first reagent tray outer ring is filled with a first reagent, and the reagent bottle of the first reagent tray inner ring is filled with a second reagent; the first reagent needle assembly includes a first inner reagent needle and a first outer reagent needle; the first outer reagent needle is disposed on the frame and can move relative to the frame, and is used to absorb the first reagent in the reagent bottle of the outer ring of the first reagent tray and transfer it to the reaction cup of the outer ring reagent adding work position No. 1, the first inner reagent needle is disposed on the frame and can move relative to the frame, and is used to absorb the second reagent in the reagent bottle of the inner ring of the first reagent tray and transfer it to the reaction cup of the outer ring reagent adding work position No. 2.

[0026] In some embodiments, the motion trajectory of the first inner reagent needle does not intersect with the motion trajectory of the first outer reagent needle. The inner ring of the first reagent disk and the outer ring of the first reagent disk can rotate independently of each other. This design makes the acquisition and transfer of reagents more efficient. The rotation of the reagent disk can be flexibly adjusted as needed, so as to quickly locate the required reagent bottle, reduce waiting time, and improve overall work efficiency. Due to the independent rotation design of the inner ring and the outer ring, the equipment can better control the rotation speed and direction during operation, reduce 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, which are used to absorb reagents from the inner ring and the outer ring of the first reagent disk, respectively. This double-needle design not only improves the transfer speed of the reagent, but also allows the extraction of reagents at different positions at the same time, further improving the processing capacity of the equipment. The movement trajectories of the first internal reagent needle and the first external reagent needle do not intersect, which can avoid interference and collision between the first internal reagent needle and the first external reagent needle during movement, resulting in damage or jamming, and also ensure that no cross contamination occurs during the reagent transfer process. This design is particularly important for the analyzer, because cross contamination may cause errors in the analysis results and affect the accuracy of the experiment. The design also allows the use of multiple reagents in the same experiment at the same time to meet different experimental needs. This flexibility enables the analyzer to be widely used in a variety of biochemical detection scenarios to meet diverse experimental requirements. In summary, this implementation method further improves the efficiency, accuracy and ease of operation of the analyzer by optimizing the structural design of the first reagent disk assembly, providing users with a better analysis experience.

[0027] In some embodiments, the analyzer also includes a second reagent tray assembly disposed on the frame, the second reagent tray assembly including a second reagent tray inner ring loaded with reagent bottles and a second reagent tray outer ring, the second reagent tray outer ring is sleeved on the second reagent tray inner ring, and the second reagent tray inner ring and the second reagent tray outer ring can rotate independently of each other, the reagent bottles in the outer ring of the second reagent tray contain a first reagent, and the reagent bottles in the inner ring of the second reagent tray contain 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 can move relative to the frame, and is used to absorb the first reagent in the reagent bottle in the outer ring of the second reagent tray and transfer it to the reaction cup of the inner ring reagent adding work position No. 1, the second inner reagent needle is disposed on the frame and can move relative to the frame, and is used to absorb the second reagent in the reagent bottle in the inner ring of the second reagent tray and transfer it to the reaction cup of the inner ring reagent adding work position No. 2.

[0028] In some embodiments, the motion trajectory of the second inner reagent needle does not intersect with the motion trajectory of the second outer reagent needle. The inner ring of the second reagent disk and the outer ring of the second reagent disk can rotate independently of each other. This design makes the acquisition and transfer of reagents more efficient. The rotation of the reagent disk can be flexibly adjusted as needed, so as to quickly locate the required reagent bottle, reduce waiting time, and improve overall work efficiency. Due to the independent rotation design of the inner ring and the outer ring, the device can better control the rotation speed and direction during operation, reduce vibration and instability caused by improper rotation, thereby improving the overall stability and reliability of the device. The second reagent needle assembly includes a second inner reagent needle and a second outer reagent needle, which are respectively used to absorb the reagents of the inner ring and the outer ring of the second reagent disk. This double needle design not only improves the transfer speed of the reagent, but also allows the extraction of reagents at different positions at the same time, further improving the processing capacity of the device. The motion trajectories of the second inner reagent needle and the second outer reagent needle do not intersect, which can avoid interference and collision between the second inner reagent needle and the second outer reagent needle during movement, resulting in damage or jamming, and also ensure that cross contamination does not occur during the reagent transfer process. This design is particularly important for the analyzer because cross contamination may cause errors in the analysis results and affect the accuracy of the experiment. This design also allows the use of multiple reagents in the same experiment to meet different experimental needs. This flexibility enables the analyzer to be widely used in a variety of biochemical detection scenarios to meet diverse experimental requirements. In summary, this implementation method further improves the efficiency, accuracy and ease of operation of the analyzer by optimizing the structural design of the second reagent disc assembly, providing users with a better analysis experience.

[0029] In some embodiments, the first reagent tray assembly and the second reagent tray assembly are spaced apart from each other and are respectively located on both sides of the reaction tray. By distributing the first reagent tray assembly and the second reagent tray assembly on both sides of the reaction tray, the spatial layout of the equipment is fully utilized, crowding between the components is avoided, and the rationality of the overall design is improved. The design of the separated arrangement effectively avoids interference between different reagent tray assemblies, reduces the risk of cross contamination during operation, and ensures the accuracy and reliability of the experimental results. This layout allows the operator to more conveniently access each reagent tray when taking and transferring reagents, reduces the moving distance during operation, and improves work efficiency. The component spacing arrangement makes the equipment more convenient during maintenance and cleaning, reduces the difficulty of cleaning caused by narrow space, and improves the service life and hygiene level of the equipment.

[0030] In some embodiments, the first reagent needle assembly and the second reagent needle assembly can be mounted to the frame by linear guides and / or rotating rocker arms to achieve the movement of the first reagent needle assembly and the second reagent needle assembly relative to the frame. The use of linear guides and rotating rocker arms enables the reagent needle assembly to achieve high-precision movement, and this precise control is essential for the extraction and transfer process of the reagent, ensuring the accurate positioning and effective extraction of the reagent, thereby improving the reliability of the experiment. This design can not only support the linear movement of the reagent needle, but also achieve multi-dimensional movement, expanding the function of the device. For example, through linear guides, the reagent needle assembly can move smoothly on a set track, while the rotating rocker arm allows the reagent needle assembly to operate at different angles. This flexibility enables the device to adapt to different types of reagent bottles and reaction cup layouts to meet diverse experimental needs. For example, by rotating the rocker arm, the reagent needle can be operated at different angles to adapt to more complex experimental needs.

[0031] In some embodiments, the rotating rocker arm includes a first rocker arm assembly and a second rocker arm assembly which are arranged on the frame and whose motion trajectories do not interfere with each other, the first rocker arm assembly is arranged between the reaction disk and the first reagent disk assembly, the second rocker arm assembly is arranged 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 which are arranged on the frame and whose motion trajectories do not interfere with each other, the first inner rocker arm is connected to the first inner reagent needle and is used to drive the first inner reagent needle to move, the first outer rocker arm is connected to the first outer reagent needle and is used to drive the first outer reagent needle to move, the second rocker arm assembly includes a second inner rocker arm and a second outer rocker arm which are arranged on the frame and whose motion trajectories do not interfere with each other, the second inner rocker arm is connected to the second inner reagent needle and is used to drive the second inner reagent needle to move, the second outer rocker arm is connected to the second outer reagent needle and is used to drive the second outer reagent needle to move. The independent design of the first rocker arm assembly and the second rocker arm assembly ensures that the movements of the two reagent needles will not interfere with each other during operation. This independence enables the device to process different reagents at the same time, improving the efficiency and flexibility of the experiment. The first inner rocker arm and the first outer rocker arm are respectively connected to the corresponding reagent needle, which can accurately control the movement trajectory of the reagent needle. This precise control is essential to ensure accurate extraction and transfer of reagents and reduce operational errors. By configuring the first inner rocker arm, the first outer rocker arm, the second inner rocker arm, and the second outer rocker arm separately, the design can more effectively utilize the rack space, making the device more compact in structure and adapting to the needs of different laboratory environments. At the same time, this design can also reduce the overall size of the device and facilitate operation and maintenance.

[0032] In some embodiments, the inner ring of the reaction disk and the outer ring of the reaction disk can rotate independently of each other. The inner ring and outer ring of the reaction disk are independently driven by rotation, and different test speeds and cycle timings can be set according to actual needs. This flexibility enables the device to adapt to a variety of experimental requirements and improves the efficiency and accuracy of the test. The inner ring and outer ring of the reaction disk can be set to rotate in opposite directions, and this design allows operation under the same cycle timing. In this way, the work of the inner ring and the outer ring can be effectively coordinated to ensure that the reaction conditions of different reagents and samples remain consistent during the experiment, thereby improving the reliability of the experiment. Due to the independent rotation drive of the inner ring and the outer ring, 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 the stirring and mixing between reagents and samples more efficient, can better promote the reaction, and improve the uniformity and speed of the reaction.

[0033] In some embodiments, the analyzer also includes a photometer, a cleaning mechanism, a sample stirring assembly and a reagent stirring assembly which are arranged on the frame and distributed around the reaction disk; the photometer can respectively perform photoelectric data collection on the reaction cups on the outer circle photoelectric collection workstation and the inner circle photoelectric collection workstation to obtain the test reaction data in the reaction cups; the cleaning mechanism can perform multi-stage cleaning on the reaction cups on the outer circle reaction cup multi-stage cleaning workstation and the inner circle reaction cup multi-stage cleaning workstation; the sample stirring assembly can perform sample stirring and mixing actions on the reaction cups on the outer circle sample stirring and mixing workstation and the inner circle sample stirring and mixing workstation to mix the first reagent and the sample in the reaction cup to form a reaction liquid; the reagent stirring assembly can perform reagent stirring and mixing actions on the reaction cups on the outer circle reagent stirring and mixing workstation and the inner circle reagent stirring and mixing workstation to mix the second reagent in the reaction cup and the reaction liquid.

[0034] In some embodiments, the analyzer further includes a track and a sample needle assembly, the track is arranged on the frame, and the sample needle assembly can be mounted to the frame through a linear guide and / or a rotating rocker arm to achieve the movement of the sample needle assembly relative to the frame; the sample needle assembly is arranged between the track and the reaction disk, and the sample needle assembly includes a first sample needle and a second sample needle arranged on the frame and whose movement trajectories do not interfere with each other, the first sample needle is used to absorb the sample on the track and transfer it to the reaction cup of the inner ring plus sample working position of the reaction disk, and the second sample needle is used to absorb the sample on the track and transfer it to the reaction cup of the outer ring plus sample working position. The sample needle assembly can be mounted to the frame through a linear guide and / or a rotating rocker arm to achieve the flexible movement of the sample needle assembly relative to the frame. This design improves the efficiency of sample transfer, so that the sample can be quickly transferred from the track to the designated working position of the reaction disk. The movement trajectories of the first sample needle and the second sample needle do not interfere with each other, ensuring that no collision or interference occurs during the sample transfer process. This design improves the safety and stability of the device and avoids potential errors in the sample transfer process. The first sample needle is responsible for transferring the sample from the track to the cuvette with the inner ring plus sample working position, while the second sample needle transfers the sample to the cuvette with the outer ring plus sample working position. This division of labor design enables the analyzer to process multiple samples at the same time, improving the parallel processing capability and overall efficiency of the experiment. The design of the sample needle assembly between the track and the reaction disk effectively utilizes the equipment space and reduces the footprint of the equipment. This compact layout makes the equipment more flexible and easy to operate in a laboratory environment. Through the integration of the track and sample needle assembly, the analyzer achieves a higher level of automation and reduces the need for manual intervention. This automation function not only improves work efficiency, but also reduces the risk of human error and ensures the reliability of experimental results. BRIEF DESCRIPTION OF THE DRAWINGS

However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0041] See also 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 arranged on the frame 100 and includes a reaction disk inner ring 310 loaded with reaction cups and a reaction disk outer ring 320; the rotation track of the reaction disk outer ring 320 is provided with an outer ring photoelectric collection workstation 1, an outer ring reagent adding workstation No. 1 2, an outer ring sample adding workstation 3, an outer ring sample stirring and mixing workstation 4, an outer ring reagent adding workstation No. 2 5, an outer ring reagent stirring and mixing workstation 6 and an outer ring reaction cup multi-stage cleaning workstation 7; the rotation track of the reaction disk inner ring 310 is provided with an inner ring photoelectric collection workstation 11, an inner ring reagent adding workstation No. 1 12, an inner ring sample adding workstation 13, an inner ring sample stirring and mixing workstation 14, an inner ring reagent adding workstation No. 2 15, an inner ring reagent stirring and mixing workstation 16 and an inner ring reaction cup multi-stage cleaning workstation 17; the first reagent needle assembly 610 is arranged on the frame 100 and can move relative to the frame 100, and is used to add the first reagent needle assembly 610 to the reaction disk inner ring 310; The first reagent is transferred to the reaction cup of the outer ring reagent adding workstation No. 1 2 and the outer ring reagent adding workstation No. 2 5; the second reagent needle assembly 620 is arranged on the frame 100 and can move relative to the frame 100, and is used to transfer the second reagent to the reaction cup of the inner ring reagent adding workstation No. 1 12 and the inner ring reagent adding workstation No. 2 15; wherein, the angle between the line connecting the outer ring reagent adding workstation No. 1 2 and the center of the reaction disk 300 and the line connecting the inner ring reagent adding workstation No. 1 12 and the center of the reaction disk 300 is greater than 90°; the angle between the line connecting the outer ring reagent adding workstation No. 2 5 and the center of the reaction disk 300 and the line connecting the inner ring reagent adding workstation No. 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 both sides of the reaction disk 300.

[0042] The above-mentioned analyzer 10 can at least achieve the following beneficial effects: the angle between the line connecting the outer ring reagent workstation No. 1 2 and the center of the reaction disk 300 and the line connecting the inner ring reagent workstation No. 1 12 and the center of the reaction disk 300 is greater than 90°, that is, the positions of the outer ring reagent workstation No. 1 2 and the inner ring reagent workstation No. 1 12 are relatively far away, almost located on both sides of the reaction disk 300; the angle between the line connecting the outer ring reagent workstation No. 2 5 and the center of the reaction disk 300 and the line connecting the inner ring reagent workstation No. 2 15 and the center of the reaction disk 300 is greater than 90°, that is, the positions of the outer ring reagent workstation No. 2 5 and the inner ring reagent workstation No. 2 15 are relatively far away, almost located on both sides of the reaction disk 300, so the corresponding first reagent needle assembly 610 and the second reagent needle assembly 620 can also be arranged on both sides of the reaction disk 300, which can avoid the component layout being too crowded, which not only improves the convenience of operation, but also reduces the risk of operational errors caused by narrow space. The dispersed workstation layout effectively avoids mutual interference between different operations, ensuring that operations such as sample filling, reagent addition, and photoelectric detection can be performed independently, improving the overall stability of the equipment. Reasonable layout makes it easier to clean and maintain the equipment, and operators can more easily access each workstation, reducing maintenance costs and increasing the service life of the equipment.

[0065] Further, the motion trajectory of the second inner reagent needle 621 does not intersect with the motion trajectory of the second outer reagent needle 622. The second reagent disk inner ring 521 and the second reagent disk outer ring 522 can rotate independently of each other. This design makes the acquisition and transfer of reagents more efficient.

This flexibility enables the analyzer 10 to be widely used in a variety of biochemical detection scenarios to meet diverse experimental requirements. In summary, this embodiment further improves the efficiency, accuracy and ease of operation of the analyzer 10 by optimizing the structural design of the second reagent disk assembly 520, providing users with a better analysis experience.

[0066] like Figure 1 and Figure 2 As shown, in some embodiments, the first reagent disc assembly 510 and the second reagent disc assembly 520 are arranged at intervals from each other and are respectively located on both sides of the reaction disc 300. By distributing the first reagent disc assembly 510 and the second reagent disc assembly 520 on both sides of the reaction disc 300, the spatial layout of the equipment is fully utilized, the crowding between the components is avoided, and the rationality of the overall design is improved. The design of the separated arrangement effectively avoids the interference between different reagent disc assemblies, reduces the risk of cross contamination during operation, and ensures the accuracy and reliability of the experimental results. This layout allows the operator to more conveniently contact each reagent disc when taking and transferring the reagent, reduces the moving distance during operation, and improves work efficiency. The component interval arrangement makes the equipment more convenient when maintaining and cleaning, reduces the cleaning difficulty caused by narrow space, and improves the service life and sanitation 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 by linear guides and / or rotating rocker arms to achieve the 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 enables the reagent needle assembly to achieve high-precision movement, and this precise control is essential for the extraction and transfer process of the reagent, ensuring the accurate positioning and effective extraction of the reagent, thereby improving the reliability of the experiment. This design can not only support the linear movement of the reagent needle, but also achieve multi-dimensional movement, expanding the function of the device. For example, through linear guides, the reagent needle assembly can move smoothly on a set track, while the rotating rocker arm allows the reagent needle assembly to operate at different angles. This flexibility enables the device to adapt to different types of reagent bottles and reaction cup layouts to meet diverse experimental needs. For example, by rotating the rocker arm, the reagent needle can be operated at different angles to adapt to more complex experimental needs.

[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 which are arranged on the frame 100 and whose motion trajectories do not interfere with each other, the first rocker arm assembly 710 is arranged between the reaction disk 300 and the first reagent disk assembly 510, the second rocker arm assembly 720 is arranged 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 which are arranged on the frame 100 and whose motion trajectories do not interfere with each other, the first inner rocker arm 711 and the first inner reagent disk assembly 510 are arranged between the first rocker arm assembly 710 and the first outer rocker arm 712, the first inner rocker arm 711 and the first inner reagent disk assembly 510 are arranged between the first rocker arm assembly 710 and the first outer rocker arm 712. The first inner reagent needle 611 is connected and used to drive the first inner reagent needle 611 to move, the first outer rocker arm 712 is connected to the first outer reagent needle 612 and used to drive the first outer reagent needle 612 to move, the second rocker arm assembly 720 includes a second inner rocker arm 721 and a second outer rocker arm 722 which are arranged on the frame 100 and whose motion trajectories do not interfere with each other, the second inner rocker arm 721 is connected to the second inner reagent needle 621 and used to drive the second inner reagent needle 621 to move, and the second outer rocker arm 722 is connected to the second outer reagent needle 622 and used to drive the second outer reagent needle 622 to move. The independent design of the first rocker arm assembly 710 and the second rocker arm assembly 720 ensures that the movement of the two reagent needles will not interfere with each other during operation. This independence enables the device to process different reagents at the same time, improving the efficiency and flexibility of the experiment. The first inner rocker arm 711 and the first outer rocker arm 712 are respectively connected to the corresponding reagent needles, and can accurately control the motion trajectory of the reagent needle. This precise control is crucial to ensure the accurate extraction and transfer of reagents, reducing operational errors. By 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 separately, the design can more effectively utilize the rack 100 space, making the device more compact in structure and adapting to the needs of different laboratory environments. At the same time, this design can also reduce the overall volume of the device and facilitate operation and maintenance.

[0069] like Figure 1 and Figure 2As shown, in some embodiments, the inner ring 310 of the reaction disk and the outer ring 320 of the reaction disk can rotate independently of each other. The inner ring 310 and the outer ring of the reaction disk are independently driven by rotation, and different test speeds and cycle timings can be set according to actual needs. This flexibility enables the device to adapt to a variety of experimental requirements and improves the efficiency and accuracy of the test. The inner ring 310 and the outer ring of the reaction disk can be set to rotate in opposite directions, and this design allows operation under the same cycle timing. In this way, the work of the inner ring and the outer ring can be effectively coordinated to ensure that the reaction conditions of different reagents and samples remain consistent during the experiment, thereby improving the reliability of the experiment. Due to the independent rotation drive of the inner ring and the outer ring, 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 the stirring and mixing between reagents and samples more efficient, can better promote the reaction, and improve the uniformity and speed of the reaction.

[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, which are arranged on the rack 100 and distributed around the reaction disk 300; the photometer 210 can respectively perform photoelectric data collection on the reaction cups on the outer ring photoelectric collection workstation 1 and the inner ring photoelectric collection workstation 11 to obtain the test reaction data in the reaction cups; the cleaning mechanism 220 can perform photoelectric data collection on the outer ring reaction cup multi-stage cleaning workstation 7 and the inner ring reaction cup multi-stage cleaning workstation 11. The reaction cup on the cup multi-stage cleaning workstation 17 performs multi-stage cleaning; the sample stirring component 230 can perform sample stirring and mixing actions on the reaction cups on the outer circle sample stirring and mixing workstation 4 and the inner circle sample stirring and mixing workstation 144, and mix the first reagent and the sample in the reaction cup to form a reaction liquid; the reagent stirring component 240 can perform reagent stirring and mixing actions on the reaction cups on the outer circle reagent stirring and mixing workstation 6 and the inner circle reagent stirring and mixing workstation 16, and mix the second reagent in the reaction cup and the reaction liquid.

The sample needle assembly 400 can be mounted to the frame 100 through a linear guide and / or a rotating rocker arm, so as to achieve the flexible movement of the sample needle assembly 400 relative to the frame 100. This design improves the efficiency of sample transfer, allowing samples to be quickly transferred from the track to the designated working position of the reaction disk 300. The movement trajectories of the first sample needle 410 and the second sample needle 420 do not interfere with each other, ensuring that no collision or interference occurs during the sample transfer process. This design improves the safety and stability of the device and avoids potential errors in the sample transfer process. The first sample needle 410 is responsible for transferring the sample from the track to the reaction cup of the inner circle plus sample working position 13, while the second sample needle 420 transfers the sample to the reaction cup of the outer circle plus sample working position 3. This division of labor design enables the analyzer 10 to process multiple samples at the same time, improving the parallel processing capability and overall efficiency of the experiment. The design of the sample needle assembly 400 between the track and the reaction disk 300 effectively utilizes the equipment space and reduces the footprint of the equipment. This compact layout makes the device more flexible and easy 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 and reduces the need for manual intervention. This automation function not only improves work efficiency, but also reduces the risk of human error and ensures the reliability of experimental results.
