Description

Technical Field

[0001] This utility model relates to the field of fluorescence detection equipment technology, and in particular to a fluorescence immunochromatographic analyzer. Background Technology

[0002] When using a fluorescence immunochromatographic analyzer, target molecules (such as antigens or antibodies) in the sample bind to specific antibodies or antigens labeled with fluorescence to form complexes. Subsequently, inside the instrument, an excitation light source illuminates the reaction area, exciting the fluorescent label and causing it to fluoresce. The analyzer detects these fluorescence signals and quantifies the content of the target molecules in the sample based on the relationship between fluorescence intensity and target molecule concentration. This method improves the sensitivity and accuracy of detection, allowing for precise measurements of low concentrations of target molecules. However, in related technologies, fluorescence immunochromatographic analyzers typically require reagent cards for testing. Because operators may use varying degrees of force when inserting the reagent cards, they may not be able to accurately position them at the test location, affecting subsequent measurement results and leading to inaccurate readings. Utility Model Content

[0003] This invention provides a fluorescence immunochromatographic analyzer to address the shortcomings of existing technologies where inaccurate positioning leads to inaccurate results, thereby improving the positioning accuracy of reagent cards.

[0004] This utility model provides a fluorescence immunochromatographic analyzer, comprising:

[0005] Base;

[0006] Detection component, the detection component being used to detect reagent cards;

[0007] A snap-fit ​​assembly is movably disposed on the base. The snap-fit ​​assembly has an installation position and a detection position, wherein the reagent card is installed in the installation position and the reagent card is detected by the detection assembly in the detection position.

[0008] A scanning component is fixedly connected to the base and is used to scan the positioning tag on the reagent card to determine whether the reagent card has reached the detection position.

[0009] In some embodiments, the fluorescence immunochromatographic analyzer includes a guide rail assembly disposed on the base, the guide rail assembly comprising:

[0010] A driving element and a guide rail, the guide rail extending along a first direction, the driving element being connected to the guide rail to drive the guide rail to rotate;

[0011] A slider is slidably disposed on the guide rail along a first direction, and the snap-fit ​​assembly is fixedly connected to the slider.

[0012] In some embodiments, the slider includes a sliding portion and a mounting portion connected together. The sliding portion is slidably connected to the guide rail, and the mounting portion extends along a second direction perpendicular to the first direction. The snap-fit ​​assembly is fixedly connected to the mounting portion.

[0013] In some embodiments, the scanning assembly includes a support and a scanning module. The support includes a first plate and a second plate connected together. The first plate extends along a third direction, which is perpendicular to both the first direction and the second direction. One end of the first plate is fixedly connected to the base, and the other end of the first plate is fixedly connected to the second plate. The scanning module is disposed on the second plate.

[0014] In some embodiments, the first plate and the snap-fit ​​assembly are respectively disposed on both sides of the guide rail in the second direction.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0035] like Figures 1 to 5 As shown, the fluorescence immunochromatographic analyzer of this embodiment includes a base 1, a detection component 2, a snap-fit ​​component 3, and a scanning component 4.

[0036] Detection component 2 is used to detect reagent card 200.

[0037] The snap-fit ​​assembly 3 is movably mounted on the base 1. The snap-fit ​​assembly 3 has an installation position and a detection position. The installation position is for installing the reagent card 200, and the detection position is for the detection assembly 2 to detect the reagent card 200.

[0038] The scanning component 4 is fixedly connected to the base 1. The scanning component 4 is used to scan the label on the reagent card 200 to determine whether the reagent card 200 has reached the detection position.

[0039] For example, the target substance (such as an antigen or antibody) in the reagent card 200 binds to a specific antibody or antigen with a fluorescent label to form a complex. Subsequently, the reagent card 200 is irradiated with the detection component 2, thereby exciting the fluorescent label and causing it to emit fluorescence, thus obtaining the detection result.

[0040] Optionally, the detection component 2 includes an analysis module and a display module. The analysis module performs fluorescence analysis and calculations based on the results emitted by the reagent card 200, and the display module is used to display the final results.

[0041] The snap-fit ​​component 3 is mounted on the base 1 and can move in the left and right directions.

[0042] The snap-fit ​​assembly 3 is provided with a slot 321, and one end of the snap-fit ​​assembly 3 is provided with an inlet 322, through which the reagent card 200 can enter the slot 321.

[0043] In operation, the fluorescence immunochromatographic analyzer of this embodiment first moves the locking assembly 3 to the installation position and installs the reagent card 200 in the card slot 321. Then, the locking assembly 3 moves to the detection position. At the detection position, the scanning assembly 4 scans the positioning tag on the reagent card 200 to determine whether the reagent card 200 has reached the detection position. If the scan result shows that the reagent card 200 has reached the detection position, the controller controls the detection assembly 2 to start to detect the reagent card 200. If the scan result shows that the reagent card 200 has not reached the detection position, the controller adjusts the position of the locking assembly 3 until the scanning assembly 4 detects the positioning tag.

[0044] In related technologies, fluorescence immunochromatographic analyzers usually require the insertion of reagent cards 200 for testing. However, after the reagent cards 200 are installed in the card slot 321, they are often not positioned accurately, which will result in poor accuracy of subsequent measurement results.

[0045] In this embodiment of the fluorescence immunochromatographic analyzer, during use, the reagent card 200 is inserted into the card slot 321. After being limited by the card slot 321, the detection is started. The card engaging component 3 moves the reagent card 200 to the scanning area of ​​the scanning component 4. The scanning component 4 can identify the positioning tag on the reagent card 200 to determine whether the reagent card 200 is inserted correctly. This reduces the possibility of inaccurate results due to the reagent card 200 not being inserted correctly, improves the accuracy of the detection results, and reduces the process of manually adjusting the reagent card 200, thereby improving the detection efficiency.

[0046] In other embodiments, the snap-fit ​​assembly 3 includes a stop member 33 that can abut against the reagent card 200 to secure the reagent card 200 in the card slot 321.

[0047] In some embodiments, such as Figure 1 and Figure 2 As shown, the fluorescence immunochromatographic analyzer includes a guide rail assembly 5, which is mounted on a base 1. The guide rail assembly 5 includes a drive member 51, a guide rail 52, and a slider 53. The guide rail 52 extends along a first direction, and the drive member 51 is connected to the guide rail 52 to drive the guide rail 52 to rotate.

[0048] The slider 53 is slidably disposed on the guide rail 52 along the first direction, and the snap-fit ​​component 3 is fixedly connected to the slider 53.

[0049] For example, for ease of description, we will use the left and right directions as the first direction below.

[0050] The guide rail assembly 5 includes a drive unit 51, a guide rail 52 extending in a first direction, i.e., the left-right direction, and a slider 53 slidably mounted on the guide rail 52. The drive unit 51 is connected to the guide rail 52 to drive the guide rail 52 to rotate, thereby enabling the slider 53 to move smoothly in the left-right direction. The locking assembly 3 is fixedly connected to the slider 53. In this way, when it is necessary to move the reagent card 200 from the installation position to the detection position, the drive unit 51 can drive the slider 53 and the locking assembly 3 on it to move along the extension direction of the guide rail 52, i.e., the left-right direction, ensuring that the reagent card 200 can accurately reach the predetermined detection position for subsequent scanning and detection.

[0051] Optionally, guide rail 52 is a lead screw.

[0052] In some embodiments, such as Figure 2 As shown, the slider 53 includes a sliding part 531 and a mounting part 532 connected together. The sliding part 531 is slidably connected to the guide rail 52, and the mounting part 532 extends along a second direction, which is perpendicular to the first direction. The snap-fit ​​assembly 3 is fixedly connected to the mounting part 532.

[0053] For example, for ease of description, the forward and backward direction will be referred to as the second direction below.

[0054] The slider 53 includes a sliding part 531 and a mounting part 532 connected to each other. The sliding part 531 is located behind the mounting part 532 and is slidably connected to the guide rail 52. The mounting part 532 extends in the front-back direction. The snap-fit ​​component 3 is fixedly connected to the mounting part 532. When the driving member 51 drives the slider 53 to move in the left-right direction through the guide rail 52, the snap-fit ​​component 3 is driven to switch between the mounting position and the detection position.

[0055] Optionally, the base 1 is provided with a guide rod, and the bottom of the mounting part 532 is slidably connected to the guide rod.

[0056] In some embodiments, such as Figure 2 As shown, the scanning component 4 includes a bracket 41 and a scanning module 42. The bracket 41 includes a first plate 411 and a second plate 412 connected together. The first plate 411 extends along a third direction, which is perpendicular to both the first and second directions. One end of the first plate 411 is fixedly connected to the base 1, and the other end of the first plate 411 is fixedly connected to the second plate 412. The scanning module 42 is disposed on the second plate 412.

[0057] For example, for ease of description, the vertical direction will be used as the third direction below. The lower end of the first plate 411 is fixed to the base 1 to ensure the stability of the entire bracket 41, while the upper end of the first plate 411 is fixedly connected to the second plate 412, so that the second plate 412 can be stably positioned in a predetermined position. The scanning module 42 is installed on the second plate 412. The scanning module 42 is set higher than the snap-fit ​​assembly 3, so as to facilitate scanning the positioning label on the reagent card 200.

[0058] Optionally, the first plate 411 is bolted to the base 1, or the first plate 411 is welded to the base 1. The second plate 412 is integrally formed with the first plate 411.

[0059] In some embodiments, such as Figure 2 As shown, the first plate 411 and the snap-fit ​​assembly 3 are respectively located on both sides of the guide rail 52 in the second direction.

[0060] For example, the first plate 411 is arranged behind the guide rail 52, and the snap-fit ​​assembly 3 is arranged in front of the guide rail 52. This not only helps to optimize the space utilization of the fluorescence immunochromatographic analyzer and reduce interference with the snap-fit ​​assembly 3, but also ensures that the functions of the scanning assembly 4 and the snap-fit ​​assembly 3 are realized efficiently.

[0061] In some embodiments, such as Figure 2 As shown, the second plate 412 extends upward from the top of the first plate 411 and is inclined toward the mounting portion 532.

[0062] For example, the second plate 412 is not vertically upward, but extends at a certain angle towards the mounting part 532 in the snap-fit ​​assembly 3. That is, the second plate 412 is tilted forward, which facilitates its adaptation with the snap-fit ​​assembly 3, so that the scanning module 42 can be in a suitable angle and position to scan the positioning label on the reagent card 200, thereby improving the reliability of the fluorescence immunochromatographic analyzer.

[0063] In some embodiments, such as Figure 3 As shown, the detection component 2 includes a support frame 21, which includes a support plate 211, a first leg 212, and a second leg 213. The support plate 211 extends along the second direction and is positioned higher than the snap-fit ​​component 3. The first leg 212 and the second leg 213 are respectively located at both ends of the support plate 211. The support plate 211 is provided with detection holes.

[0064] The support frame 21 consists of a support plate 211, a first leg 212, and a second leg 213. The support plate 211 extends along the second direction, i.e., the front-to-back direction, and is positioned above the snap-fit ​​assembly 3 to ensure that it does not interfere with the moving snap-fit ​​assembly 3 during the testing process.

[0065] The first leg 212 and the second leg 213 are respectively connected to the two ends of the support plate 211 to provide necessary support and ensure the stability of the entire support frame 21. It is worth noting that a detection hole is provided on the support plate 211. This design is to allow the detection module 22 to accurately detect the reagent card 200 through this hole, so that light or sensors can directly act on a specific area on the reagent card 200, thereby achieving an efficient and accurate analysis process.

[0066] In some embodiments, such as Figure 1 As shown, the detection component 2 includes a detection module 22, which is fixed above the support plate 211. The detection module 22 can detect the reagent card 200 through the detection hole.

[0067] For example, the detection assembly 2 includes a detection module 22, which is fixedly mounted above the support plate 211 to ensure that it is stably and accurately aligned with the reagent card 200 below. The support plate 211 has a detection hole. This layout allows the detection module 22 to directly detect the reagent card 200 placed in the snap-fit ​​assembly 3 through the detection hole. This design not only ensures the efficiency and accuracy of the detection process, but also reduces the interference of external factors on the detection results.

[0068] In other embodiments, the guide rail assembly 5 is provided with a position sensor for detecting the position of the slider 53.

[0069] The position sensor is used to detect the position of the slider 53, ensuring that the slider 53 and the latching assembly 3 connected to it can move accurately to the predetermined position.

[0070] In some embodiments, such as Figure 2 As shown, the snap-fit ​​assembly 3 includes a support base 31 and a snap-fit ​​member 32. The support base 31 is located at the bottom of the snap-fit ​​member 32 and is connected to the guide rail assembly 5. The snap-fit ​​member 32 is provided with a snap-fit ​​groove for installing the reagent card 200.

[0071] The support base 31 is located at the bottom of the snap-fit ​​component 32 and is fixedly connected to the mounting part 532. This design provides a stable foundation for the snap-fit ​​component 3 and ensures its smooth movement on the guide rail 52. The snap-fit ​​component 32 is provided with a snap-fit ​​groove. This snap-fit ​​groove is designed to facilitate the installation of the reagent card 200, so that the reagent card 200 can be firmly and accurately fixed in the designated position for subsequent scanning and detection processes. Through this structural layout, not only is the convenience of operation and the accuracy of detection improved, but the overall stability and reliability of the equipment are also enhanced, which helps to achieve efficient and accurate analysis.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
