Description

Technical Field

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

[0002] Analyzers are essential equipment in modern medicine and chemical testing. They are mainly used to detect the concentration and activity of substances through changes in the optical properties of substances during chemical reactions. Such equipment is widely used in clinical laboratories and research institutions, and can provide test results quickly and accurately to support doctors' diagnosis and treatment decisions.

[0003] With the continuous advancement of medical technology and people's emphasis on health management, the demand for analyzer testing is increasing. Most of the existing analyzers in the industry adopt a dual measurement system design, which increases the test speed of the equipment by setting up two independent measurement systems on the same device. However, the single-machine test speed of the mainstream high-speed analyzers on the market is generally only 2000 results / hour. Due to the limitations of the design and control technology level, it is difficult to further improve.

[0004] In the traditional technical solution, although the design of the dual measurement system has improved the test efficiency to a certain extent, it also has many shortcomings. First, the dual system working solution requires the installation of two sets of reagent management and dispensing subsystems, which leads to the complexity of the equipment structure and the difficulty of maintenance. If one of the dispensing subsystems fails or needs maintenance, the working efficiency of the other dispensing subsystem will also be affected, thereby reducing the working efficiency of the whole machine. In addition, when the two systems place components with similar timing in the reagent management subsystem, if the reagent of one system is exhausted, the operation of the entire equipment needs to be suspended for replenishment, which further affects the continuity and efficiency of the test. In addition, the design layout of existing products often leads to the space between the reagent disk assembly and the reagent needle assembly being too crowded, which limits the capacity of the reagent disk and the overall size of the equipment, and increases energy consumption and maintenance difficulty. Therefore, a new analyzer design scheme is urgently needed to optimize the layout of the reagent management and dispensing subsystems, improve the test speed and the operating efficiency of the equipment, and solve the defects and deficiencies in the prior art.

[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.

[0016] Wherein, the motion trajectory of the first reagent needle assembly does not intersect with the motion trajectory of the second reagent needle assembly.

[0017] The above analyzer can at least achieve the following beneficial effects: the independent design of the sample needle assembly and the reagent needle assembly allows flexible scheduling when transferring samples and adding reagents, adapting to different experimental requirements and improving the applicability of the equipment. By arranging the first reagent disk assembly and the second reagent disk assembly on both sides of the reaction disk and equipping them with independent reagent needle assemblies, the reagents can be absorbed and transferred at the same time, effectively shortening the test cycle and improving the overall test efficiency. Since the motion trajectories of the first reagent needle assembly and the second reagent needle assembly do not intersect, even if one of the reagent needle assemblies fails or requires maintenance, the other assembly can still work independently, thereby reducing the downtime of the equipment and improving the reliability and availability of the equipment. The reagent disk assembly is arranged at intervals to avoid crowding of reagent bottles, optimize the spatial layout, improve the space utilization rate inside the equipment, and facilitate maintenance and operation.

In summary, this implementation further improves the efficiency, accuracy, and ease of operation of the analyzer by optimizing the structural design of the second reagent disk assembly, providing users with a better analysis experience.

[0020] 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.

[0021] 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 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 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, 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 volume of the device and facilitate operation and maintenance.

[0022] In some embodiments, the first rocker arm assembly is disposed between the reaction disk and the first reagent disk assembly, and the second rocker arm assembly is disposed between the reaction disk and the second reagent disk assembly. The rocker arm assembly is disposed between the reaction disk and the reagent disk assembly, so that the internal space of the device can be effectively utilized and the floor space can be reduced. This compact design helps to improve the space utilization rate of the laboratory and makes the device more suitable for use in an environment with limited space.

[0023] In some embodiments, the sample needle assembly can be mounted to the frame via a linear guide and / or a rotating rocker arm to achieve movement of the sample needle assembly relative to the frame. The use of a linear guide can achieve smooth linear motion of the sample needle assembly, ensuring accuracy when extracting and transferring samples. This high-precision motion control is essential for the reliability of experimental results. Through the design of a rotating rocker arm, the sample needle assembly can achieve multi-angle motion, which enables the device to adapt to different experimental needs. For example, the sample needle can be operated at different heights and angles, which improves the flexibility of the device. The two driving modes of the linear guide and the rotating rocker arm can be used alone 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, which can ensure accurate extraction and transfer of samples. In summary, the design of the sample needle assembly being mounted to the frame via a linear guide and / or a rotating rocker arm not only improves the accuracy and flexibility of movement, but also simplifies the installation and maintenance process, providing users with an efficient, stable and intelligent experimental solution.

[0024] In some embodiments, 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 rack and having motion trajectories that 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 on the inner ring 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 on the outer ring of the reaction disk. The sample needle assembly is arranged between the track and the reaction disk, which helps to optimize the spatial layout of the device and reduce the occupied area. This compact design is suitable for laboratory environments with limited space and improves the overall space utilization of the device. The first sample needle and the second sample needle are responsible for the sample transfer of the inner ring and the outer ring respectively, so that the device can flexibly manage multiple samples. This flexibility enables the device to adapt to the needs of different experiments, meet the requirements of multi-sample processing, significantly improve the efficiency of sample transfer, reduce processing time, and is suitable for high-throughput experimental needs. By designing sample needles whose motion trajectories do not interfere with each other, interference and collision between sample needles can be avoided, the risk of damage can be reduced, and cross interference can be ensured during sample extraction and transfer. This design improves the safety and accuracy of operation and reduces the risk of sample contamination.

The track is arranged above the reaction disk, and the sample needle assembly is placed between the reaction disk and the track.

Separating the sample needle assembly and the reagent needle assembly can make it more convenient for operators to transfer samples and reagents, and simplify the maintenance and cleaning process of the equipment. Operators can more easily access each component to ensure long-term and stable operation of the equipment.

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 the movement trajectory of the reagent needle can be accurately controlled. This precise control is crucial to ensure the accurate extraction and transfer of reagents and reduce 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 space of the rack 100, 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 equipment, facilitating operation and maintenance.

[0043] In some embodiments, 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 rocker arm assembly is disposed between the reaction disk 300 and the reagent disk assembly, so that the internal space of the device can be effectively utilized and the floor space can be reduced. This compact design helps to improve the space utilization rate of the laboratory and makes the device more suitable for use in an environment with limited space.

[0044] In some embodiments, the sample needle assembly 400 can be mounted to the frame 100 via a linear guide and / or a rotating rocker arm to achieve movement of the sample needle assembly 400 relative to the frame 100. The use of linear guides can achieve smooth linear movement of the sample needle assembly 400, ensuring accuracy when extracting and transferring samples. This high-precision motion control is crucial to the reliability of experimental results. Through the design of the rotating rocker arm, the sample needle assembly 400 can achieve multi-angle movement, which enables the device to adapt to different experimental requirements. For example, the sample needle can be operated at different heights and angles, which improves the flexibility of the device. The two driving modes of linear guides and rotating rockers can be used alone or in combination, making the sample needle assembly 400 more stable during movement and reducing errors caused by vibration or imbalance. This stability is particularly important for high-precision experiments and can ensure accurate extraction and transfer of samples. In summary, the design of mounting the sample needle assembly 400 to the frame 100 via a linear guide and / or a rotating rocker arm not only improves the accuracy and flexibility of movement, but also simplifies the installation and maintenance process, providing users with an efficient, stable and intelligent experimental solution.

[0045] In some embodiments, the sample needle assembly 400 is arranged between the track 200 and the reaction disk 300, and the sample needle assembly 400 includes a first sample needle 410 and a second sample needle 420 arranged on the rack 100 and whose movement trajectories do not interfere with each other, the first sample needle 410 is used to absorb the sample on the track 200 and transfer it to the reaction cup on the inner circle 310 of the reaction disk, and the second sample needle 420 is used to absorb the sample on the track 200 and transfer it to the reaction cup on the outer circle 320 of the reaction disk. The sample needle assembly 400 is arranged between the track 200 and the reaction disk 300, which helps to optimize the spatial layout of the device and reduce the occupied area. This compact design is suitable for laboratory environments with limited space and improves the overall space utilization of the device. The first sample needle 410 and the second sample needle 420 are responsible for the sample transfer of the inner circle and the outer circle respectively, so that the device can flexibly manage multiple samples. This flexibility enables the device to adapt to the needs of different experiments, meet the requirements of multi-sample processing, significantly improve the efficiency of sample transfer, reduce processing time, and is suitable for high-throughput experimental needs. By designing sample needles with non-interfering motion trajectories, there will be no interference or collision between sample needles, reducing the risk of damage, and ensuring that there will be no cross-interference during sample extraction and transfer. This design improves the safety and accuracy of operations and reduces the risk of sample contamination.
