Description

Technical Field

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

[0002] Analyzers are indispensable equipment in modern medicine and chemical testing, primarily used to detect the concentration and activity of substances by observing changes in their optical properties during chemical reactions. These devices are widely used in clinical laboratories and research institutions, providing rapid and accurate results to support doctors' diagnostic and treatment decisions.

[0003] With the continuous advancement of medical technology and increasing emphasis on health management, the demand for analytical instruments is growing. Most existing analyzers in the industry employ a dual-measurement system design, increasing testing speed by setting up two independent measurement systems on the same device. However, the single-unit testing speed of mainstream high-speed analyzers on the market is generally only around 2000 results / hour, and its improvement is difficult due to limitations in design and control technology.

[0004] While traditional dual-measurement system designs improve testing efficiency to some extent, they also have several drawbacks. First, the dual-system approach requires two reagent management and dispensing subsystems, leading to increased structural complexity and maintenance difficulties. If one dispensing subsystem malfunctions or requires maintenance, the efficiency of the other will be affected, thus reducing overall system efficiency. Furthermore, when placing similar components in the reagent management subsystem, if one system runs out of reagents, the entire system must be paused for replenishment, further impacting testing continuity and efficiency. Additionally, the layout of existing products often results in overcrowding between reagent tray and reagent needle assemblies, limiting tray capacity and overall device size, increasing energy consumption and maintenance complexity. Therefore, a novel analyzer design is urgently needed to optimize the layout of the reagent management and dispensing subsystems, improve testing speed and operational efficiency, and address the shortcomings and deficiencies of existing technologies.

[0015] The second reagent needle assembly is disposed on the frame and is movable relative to the frame, and is used to draw the reagent from the reagent bottle on the second reagent tray assembly and transfer it to the reaction cup on the outer ring of the reaction tray;

[0016] The movement trajectory of the first reagent needle assembly does not intersect with the movement trajectory of the second reagent needle assembly.

[0017] The aforementioned analyzer achieves at least the following beneficial effects: The independent design of the sample needle assembly and reagent needle assembly allows for flexible scheduling during sample transfer and reagent addition, adapting to different experimental needs and improving the applicability of the equipment. By placing the first and second reagent tray assemblies on opposite sides of the reaction tray and equipping each with an independent reagent needle assembly, reagent aspiration and transfer can be performed simultaneously, effectively shortening the testing cycle and improving overall testing efficiency. Since the movement trajectories of the first and second reagent needle assemblies do not intersect, even if one reagent needle assembly malfunctions or requires maintenance, the other assembly can still operate independently, thereby reducing equipment downtime and improving equipment reliability and availability. The spaced arrangement of the reagent tray assemblies avoids reagent bottle congestion, optimizes the spatial layout, improves the internal space utilization of the equipment, and facilitates maintenance and operation. Simultaneously, this design also helps reduce equipment energy consumption and improve overall performance. Through a reasonable layout design, the sample and reagent transfer paths are optimized, reducing the risk of cross-contamination, ensuring the accuracy and reliability of the reaction, and thus improving the quality of the analytical results. In summary, the design of this analyzer not only improves testing efficiency and reliability, but also optimizes the operation process and spatial layout, providing users with a more efficient and convenient biochemical analysis solution.

The outer needle is mounted on the frame and movable relative to it, and is used to draw reagents from the bottles in the outer ring of the reagent tray and transfer them to the reaction cup in the inner ring of the reaction tray. The movement trajectories of the inner and outer needles do not intersect. The independent rotation of the inner and outer rings 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 aspirate 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 and outer reagent needles do not intersect, avoiding interference and collisions during movement that could lead to damage or jamming. It also ensures that cross-contamination does not occur during reagent transfer, a design particularly important for the analyzer, as cross-contamination can cause 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, by optimizing the structural design of the first reagent tray assembly, further improves the efficiency, accuracy, and ease of operation of the analyzer, providing users with a superior analytical experience.

The outer needle is also mounted on the frame and can move relative to it, and is used to draw reagents from the bottles in the outer ring and transfer them to the reaction cup in the outer ring. The movement trajectories of the inner and outer needles do not intersect. The independent rotation of the inner and outer rings 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 aspirate 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 motion trajectories of the second inner and outer reagent needles prevent interference and collisions during movement, thus avoiding damage or jamming. It also ensures no cross-contamination occurs during reagent transfer, a crucial design feature for the analyzer, as cross-contamination can lead to errors in analytical results and affect experimental accuracy.

[0020] 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.

[0021] 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 includes a first inner rocker arm and a first outer rocker arm mounted on the frame with independent motion trajectories.

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 and first outer rocker arms are respectively connected to their corresponding reagent needles, enabling precise control of the reagent needle's motion trajectory. This precise control is crucial for ensuring accurate reagent extraction and transfer, reducing 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 rack space, 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, facilitating operation and maintenance.

[0022] In some embodiments, the first rocker arm assembly is disposed between the reaction tray and the first reagent tray assembly, and the second rocker arm assembly is disposed between the reaction tray and the second reagent tray assembly. Positioning the rocker arm assembly between the reaction tray and the reagent tray assembly effectively utilizes the internal space of the equipment, reducing the floor space required. This compact design helps improve the space utilization rate of the laboratory, making the equipment more suitable for use in space-constrained environments.

[0023] In some embodiments, the sample needle assembly can be mounted to the frame via linear guides and / or a rotating rocker arm to enable movement of the sample needle assembly relative to the frame. The use of linear guides allows for smooth linear movement of the sample needle assembly, ensuring accuracy during sample extraction and transfer. This high-precision motion control is crucial for the reliability of experimental results. The rotating rocker arm design allows the sample needle assembly to move at multiple angles, enabling the device to adapt to different experimental needs. For example, the sample needle can operate at different heights and angles, increasing the flexibility of the device. The linear guides and rotating rocker arms can be used individually or in combination, making the sample needle assembly more stable during movement and reducing errors caused by vibration or imbalance. This stability is particularly important for high-precision experiments, ensuring accurate sample extraction and transfer. In summary, the design of mounting the sample needle assembly to the frame via linear guides and / or a rotating rocker arm not only improves the accuracy and flexibility of movement but also simplifies installation and maintenance processes, providing users with an efficient, stable, and intelligent experimental solution.

[0024] In some embodiments, the sample needle assembly is positioned between the track and the reaction disk. The sample needle assembly includes a first sample needle and a second sample needle mounted on the frame with non-interfering motion trajectories. The first sample needle is used to aspirate samples from the track and transfer them to a reaction cup on the inner ring of the reaction disk, while the second sample needle is used to aspirate samples from the track and transfer them to a reaction cup on the outer ring of the reaction disk. Positioning the sample needle assembly between the track and the reaction disk helps optimize the spatial layout of the equipment and reduce its footprint. This compact design is suitable for space-constrained laboratory environments, improving the overall space utilization of the equipment. The first and second sample needles are responsible for sample transfer in the inner and outer rings, respectively, allowing the equipment to flexibly manage multiple samples. This flexibility enables the equipment to adapt to different experimental needs, meet the requirements of multi-sample processing, significantly improve sample transfer efficiency, reduce processing time, and is suitable for high-throughput experiments. By designing sample needles with non-interfering motion trajectories, interference and collisions between sample needles are prevented, reducing the risk of damage, and cross-interference during sample extraction and transfer is also ensured. This design improves operational safety and accuracy and reduces the risk of sample contamination.

The first sample needle 410 is used to aspirate samples from the track 200 and transfer them to a reaction cup on the inner ring 310 of the reaction disk. The second sample needle 420 is used to aspirate samples from the track 200 and transfer them to a reaction cup on the outer ring 320 of the reaction disk. Distributing the sample needle assembly 400 between the track 200 and the reaction disk 300 helps optimize the spatial layout of the equipment and reduce its footprint. This compact design is suitable for space-constrained laboratory environments, improving the overall space utilization of the equipment. The first sample needle 410 and the second sample needle 420 are responsible for sample transfer in the inner and outer rings, respectively, enabling the equipment to flexibly manage multiple samples. This flexibility allows the equipment to adapt to different experimental needs, meet the requirements of multi-sample processing, significantly improve sample transfer efficiency, reduce processing time, and is suitable for high-throughput experimental needs. By designing sample needles whose motion trajectories do not interfere with each other, it is possible to prevent interference and collisions between sample needles, reducing the risk of damage, and also ensuring that no cross-interference occurs during sample extraction and transfer. This design improves the safety and accuracy of the operation and reduces the risk of sample contamination.

[0046] like Figure 2 As shown, in some embodiments, from a top-down view, the track 200 is located above the reaction disk 300, the sample needle assembly 400 is disposed between the reaction disk 300 and the track 200, and the first reagent needle assembly 610 and the second reagent needle assembly 620 are located on both sides of the reaction disk 300, further away from the track 200 than the reaction disk 300. Positioning the track 200 above the reaction disk 300 and placing the sample needle assembly 400 between the reaction disk 300 and the track 200 effectively utilizes experimental space, reduces the equipment's footprint, and is suitable for environments with limited space. Separating the sample needle assembly 400 and the reagent needle assembly makes sample and reagent transfer more convenient for operators, simplifying equipment maintenance and cleaning procedures. Operators can more easily access each component, ensuring long-term stable operation of the equipment.

[0047] like Figure 3As shown, in some embodiments, from a top-down view, the track 200 is located above the reaction disk 300, the sample needle assembly 400 is disposed between the reaction disk 300 and the track 200, and the first reagent needle assembly 610 and the second reagent needle assembly 620 are respectively located on both sides of the reaction disk 300, and are closer to the track 200 than the reaction disk 300. Positioning the track 200 above the reaction disk 300 and placing the sample needle assembly 400 between the reaction disk 300 and the track 200, with the reagent needle assemblies located on both sides of the reaction disk 300 and closer to the track 200, results in a more compact layout, effectively utilizing space, reducing the equipment's footprint, and making it suitable for spaces with limited space.

[0048] like Figure 4 and Figure 5 As shown, in some embodiments, from a top view, the track 200 is located to the left or right of the reaction disk 300, the sample needle assembly 400 is disposed between the reaction disk 300 and the track 200, and the first reagent needle assembly 610 and the second reagent needle assembly 620 are respectively located on both sides of the reaction disk 300 and are further away from the track 200 than the reaction disk 300.

However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.

[0051] In the description of this utility model, it should be understood that if terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0052] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0053] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0054] In this utility model, unless otherwise explicitly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact, or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0055] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this invention are for illustrative purposes only and do not represent the only possible implementation.

[0056] In this specification, the use of terms such as "an embodiment," "another implementation," etc., refers to a specific feature, structure, material, or characteristic described in connection with that embodiment or example that is included in at least one embodiment or example of the present invention. In this specification, the illustrative descriptions of the above terms do not necessarily refer to the same embodiment or example. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
