Description

Technical Field

[0001] The present invention relates to the field of optical detection technology, and in particular to a reagent disc detection device. Background Art

[0002] With the development of detection technology in the biomedical and chemical fields, reagent detection equipment has been widely used in medical diagnosis, environmental monitoring and other fields. The detection of microfluidic biochemical reagent disks requires efficient and accurate analysis of the reaction results of reagents, which makes the spectroscopic module play an important role in optical detection. However, there are some shortcomings in the design and application of existing spectroscopic modules, mainly including the following aspects:

[0003] 1. The equipment is large and lacks integration. Most existing spectrometer modules adopt a large vertical arrangement structure, which takes up a lot of equipment space and cannot meet the requirements of microfluidic detection systems for miniaturization and integration. This design limits the application of detection equipment in laboratories, especially small laboratories with limited space;

[0004] 2. Single detection channel and low detection efficiency. Currently, most spectroscopic modules use a single set of lenses for detection, which leads to low efficiency when processing samples in multiple microfluidic channels. Since the detection can only be performed one by one, it cannot meet the needs of high-throughput detection, which significantly reduces the speed of data acquisition and the accuracy of detection;

[0005] 3. The automation level is insufficient and the operation is complicated. Existing testing equipment usually requires manual installation and removal of reagent trays. This method is not only complicated to operate, but also easy to introduce human errors, reducing the detection efficiency and data accuracy. In addition, the equipment is not flexible enough in the operation of entering and exiting the warehouse during the detection process, and it is difficult to adapt to the detection needs of reagent trays of multiple specifications.

[0069] Specifically, the in-and-out bin assembly 1400 is used to improve the compatibility and use efficiency of the reagent disc 1502 detection equipment. The in-and-out bin assembly 1400 can be applied to reagent discs 1502 of different specifications, so that a single device can handle the detection requirements of various reagent discs 1502 in the laboratory, reducing equipment costs and space occupancy. This specific embodiment includes the following main parts: the in-and-out bin assembly 1400 mainly includes a limiting structure 1401, an in-and-out bin support frame 1402, a position sensor 1403 and a drive assembly 1404; the in-and-out bin support frame 1402 includes a fixed frame 1405, a limiting rod 1406 and a stepping gear rod 1407. The limiting rod 1406 and the stepping gear rod 1407 are arranged in parallel and are respectively connected to both sides of the fixed frame 1405.

The position sensor 1403 is used to detect the telescopic stroke of the limiting rod 1406 to ensure that each time the in-and-out warehouse support frame 1402 is telescoped into place, it can be detected in time. This helps the detection device to calibrate the position of the reagent disk 1502, avoiding inaccurate detection results caused by inaccurate installation position of the reagent disk 1502.

This structural design realizes the automatic puncture of the sealing film 1511 of the dilution box 1509 and the introduction of the diluent into the disc body 1503, simplifies the preparation work before the test, and improves the convenience and efficiency of the test.

[0078] The outer periphery of the mounting body 1513 is provided with an adjusting tooth ring 1522 for fine-tuning the mounting position to ensure the accurate installation of the reagent disc 1502. The magnetic mounting assembly 1500 also includes a fixing bolt, a mounting hole 1523 is provided at the bottom of the mounting body 1513, a connecting hole 1524 adapted to the mounting hole 1523 is provided on the magnet 1520, and a threaded hole 1525 is provided on the protruding structure 1521, and one end of the threaded rod of the fixing bolt passes through the mounting hole 1523, the connecting hole 1524 and the threaded hole 1525 in sequence to fix the mounting body 1513, the magnet 1520 and the protruding structure 1521.

[0080] Example 4

[0081] In this embodiment, based on the basic design in Embodiment 1 and Embodiment 2, the in-and-out bin assembly 1400 is optimized in more detail, especially the puncture structure 1508, the snap-fit ​​structure of the accommodating chamber 1507, and the anti-rotation and fixing functions of the magnetic mounting seat 1501 are improved to further improve the stability and reliability of the assembly during the detection process of the reagent disk 1502. The puncture structure 1508 includes a puncture blade 1532 and abutment walls 1533 arranged on both sides of the puncture blade 1532. The main function of the puncture blade 1532 is to puncture the sealing film 1511 of the dilution box 1509 so that the diluent enters the interior of the disk body 1503, and the abutment wall 1533 plays a role of stability and support during the puncture process to prevent the puncture blade 1532 from deflecting during the puncture process.

[0082] The puncture blade 1532 and the two groups of abutment walls 1533 are both connected to the inner wall of the liquid inlet 1506. The puncture blade 1532 is sharp and strong, and can easily puncture the sealing film 1511, while the abutment walls 1533 provide lateral support forces on both sides of the puncture blade 1532. The two groups of abutment walls 1533 enclose and form a diluent channel 1534, which is connected to the flow channel 1535 in the disc body 1503, ensuring that the diluent can smoothly flow from the dilution box 1509 to the disc body 1503, reducing the risk of liquid leakage and the uncertainty of detection.

[0083] An enclosure wall is provided around the outer periphery of the liquid inlet 1506, and the top surface of the enclosure wall is in the same plane as the top of the abutting wall 1533 to provide balanced support and stability. A liquid inlet channel 1537 is also provided on the enclosure wall, and the liquid inlet channel 1537 is connected to the diluent channel 1534. This design helps the liquid to quickly and smoothly enter the inside of the disc body 1503 after piercing the sealing film 1511, thereby avoiding liquid overflow and detection interruption.

[0084] Inside the accommodating cavity 1507 , a plurality of sets of snap-fit ​​platforms 1538 are arranged, and a closing groove 1539 is provided on the top of the snap-fit ​​platform 1538 , and a snap and protrusion 1540 matching the snap-fit ​​platform 1538 is provided on the periphery of the magnetic sheet 1510 , and these snap and protrusion 1540 are adapted to the closing groove 1539 .

[0085] An installation channel is formed between the multiple groups of engaging platforms 1538, which is used to guide the magnetic sheet 1510 and the protrusion 1540 to rotate and engage in the opening and closing groove 1539 after passing through the installation channel. This design ensures the stability of the magnetic sheet 1510 in the accommodating cavity 1507, and prevents the magnetic sheet 1510 from being dislocated due to factors such as vibration during operation. The magnetic sheet 1510 is provided with one or more groups of limiting holes 1541 around the periphery of the through hole 1512, and the limiting holes 1541 can be rotated and engaged in the opening and closing groove 1539 when subjected to external force. This limiting design improves the firmness of the engagement between the magnetic sheet 1510 and the accommodating cavity 1507 by adding additional fixing points, ensures that the magnetic sheet 1510 does not move during the detection process, and further improves the overall reliability of the device.

[0086] The inner walls of the multiple sets of snap-fit ​​platforms 1538 are enclosed to form an inner snap-fit ​​wall mechanism 1542. The inner snap-fit ​​wall mechanism 1542 is used for positioning when the mounting seat 1504 is connected to the magnetic mounting seat 1501. This positioning design can ensure accurate alignment during the installation process, reduce installation errors, and improve the overall detection accuracy. An arc-shaped guide structure 1543 is designed at the bottom of the snap-fit ​​platform 1538. This arc-shaped design plays a guiding role during the installation process, making the snap-fit ​​process smoother and effectively reducing component wear or failure caused by inaccurate snap-fit.

[0087] In order to ensure the stability when the mounting base 1504 is combined with the magnetic mounting base 1501, the bottom periphery of the mounting base 1504 is provided with an anti-rotation structure 1544, which can effectively prevent the mounting base 1504 from rotating due to external force during the detection process. The prevention of rotation is crucial to ensure the positioning of the reagent disk 1502, because even a slight rotation may lead to inaccurate test results. The mounting base 1504 is also provided with a plurality of fixing holes 1545, which are used to connect with the magnetic mounting base 1501 during installation. Through these fixing holes 1545, the mounting base 1504 and the magnetic mounting base 1501 can be firmly combined together using fixing bolts to ensure the stability of the entire assembly during the detection process and prevent loosening due to vibration or improper operation.

[0088] The magnetic sheet 1510 is preferably an iron sheet, and this material selection can ensure good adsorption between the magnetic sheet 1510 and the magnetic mounting seat 1501, and can be stably inserted into the protruding structure 1521 of the magnetic mounting seat 1501 under the action of the magnet 1520. During the detection process, the magnetic sheet 1510 can effectively fix the dilution box 1509 at a predetermined position to prevent the dilution box 1509 from shifting due to liquid movement or external force.

[0089] One or more groups of positioning holes 1531 are provided on the inner wall of the positioning structure 1515, and these positioning holes 1531 are connected to the annular installation cavity 1517, which can ensure that the reagent disk 1502 is accurately aligned during the installation process. An air pressure balance groove 1529 is provided at the connection of the straight-face structure 1527, and the air pressure balance groove 1529 is used to balance the air pressure changes inside and outside the accommodating cavity 1507 during the installation process, avoiding difficulties in component installation due to air pressure differences, and ensuring that the reagent disk 1502 can be installed smoothly under any conditions.

[0090] In the present embodiment, the height of the guide structure 1516 is preferably greater than the height of the positioning structure 1515, and the top peripheral edge thereof is provided with an arc-shaped guide surface 1530. Such a design helps to smoothly guide the reagent tray 1502 into the correct position during the installation process, reduce errors and jamming, and improve the efficiency and success rate of installation before detection. Through the further improvement of the present embodiment, the adaptability of the entire in-and-out warehouse assembly 1400 in the detection of reagent trays 1502 of different specifications has been significantly improved. The limiting design of the puncture structure 1508 and the magnetic sheet 1510, the locking mechanism of the accommodating cavity 1507, and the optimization of the anti-rotation and fixing structure make the entire detection process not only more stable and reliable, but also more simple and efficient, which helps the flexible application of reagent trays 1502 of different specifications in the laboratory and the efficient operation during the detection process.

[0091] Example 5

[0092] On the basis of the first embodiment, the present embodiment proposes a spectroscopic module 1601 for reagent disc detection, including a mounting body 1602, the mounting body 1602 has a compact structure and is designed to be convenient for integrated use with a microfluidic biochemical reagent disc. The mounting body 1602 is provided with a light receiving channel 1603 and a group or multiple component light channels 1604 arranged crosswise with the light receiving channel 1603. The light receiving channel 1603 is used to receive light from a light source, and a channel spectroscopic lens 1605 is provided at the connection between the light receiving channel 1603 and the spectroscopic channel 1604, and the channel spectroscopic lens 1605 is used to reflect the light passing through the light receiving channel 1603 into the spectroscopic channel 1604, thereby realizing effective spectroscopic separation of light between different channels. In order to achieve the diversity and efficiency of detection, the mounting body 1602 is also provided with a group or multiple component light holes 1606. Each spectroscopic hole 1606 is used to connect to an external light sensor, so as to detect the light intensity or other characteristics after spectroscopic processing. The spectroscopic hole 1606 is connected to the spectroscopic channel 1604, and a detection spectroscopic lens 1607 is provided at the connection between the spectroscopic channel 1604 and the spectroscopic hole 1606. The detection spectroscopic lens 1607 is used to reflect the light in the spectroscopic channel 1604 into the spectroscopic hole 1606 to ensure that the light can be accurately received and measured by the sensor.

[0093] In the specific implementation, the installation body 1602 adopts a modular design, and the number of spectroscopic channels 1604 and spectroscopic holes 1606 can be flexibly increased or decreased to meet different detection requirements. The light receiving channel 1603 can receive light from multiple angles, accurately split it through the channel spectroscopic lens 1605, and then transmit the light to the corresponding spectroscopic holes 1606 through multiple spectroscopic channels 1604. The setting of the detection spectroscopic lens 1607 ensures that each spectroscopic hole 1606 can obtain accurate spectroscopic light and transmit it to the corresponding light sensor. The design of the spectroscopic module 1601 also takes into account the miniaturization requirements of the overall equipment. The light receiving channel 1603, the spectroscopic channel 1604 and the spectroscopic hole 1606 are tightly integrated by a horizontal arrangement, so that the volume of the entire spectroscopic module 1601 is significantly reduced, which is very suitable for the detection scenario of the microfluidic biochemical reagent disk. The modular structure is not only convenient for installation and disassembly, but also allows the spectrometer module 1601 to be expanded according to specific needs to adapt to the installation requirements of multiple groups of light lenses, thereby improving detection efficiency and data accuracy.

[0094] In practical applications, the light receiving channel 1603 can select light of a specific wavelength to enter the spectroscopic module 1601 by setting different optical filters. After the light passes through the channel spectroscopic lens 1605, it is distributed to different spectroscopic channels 1604, and each spectroscopic channel 1604 is connected to a different detection spectroscopic lens 1607 and a spectroscopic hole 1606, so that the optical properties of different reaction areas in the microfluidic biochemical reagent disk can be detected. Through this design, it is possible to achieve synchronous detection of multiple biochemical indicators in the microfluidic reaction process, thereby improving detection efficiency and accuracy. This embodiment not only realizes efficient detection of multiple channels of the microfluidic biochemical reagent disk, but also improves the miniaturization level of the entire detection system by designing the optical spectroscopic module 1601 as a modular and compact structure, and is suitable for various miniaturized equipment application scenarios that require efficient detection.

[0095] Example 6

[0096] Based on Example 1. In this embodiment, the structure of the spectroscopic module 1601 is further optimized to meet the multi-channel detection requirements of the microfluidic biochemical reagent disk. Specifically, this embodiment is based on the basic structure of the independent claim, and through further optimal design, the detection performance and installation convenience of the spectroscopic module 1601 are improved.

[0097] First, the spectroscopic channels 1604 in the spectroscopic module 1601 are arranged in multiple groups, and the multi-component optical channels 1604 are respectively located on both sides of the light receiving channel 1603. Such a design enables the spectroscopic channels 1604 to receive and disperse the light from the light receiving channel 1603 more evenly, thereby realizing the synchronous detection of multiple detection areas in the reagent disk. Each component of the optical channel 1604 is connected to the light receiving channel 1603, and the light is dispersed into each spectroscopic channel 1604 through the channel spectroscopic lens 1605 after receiving, so as to realize the multi-directional distribution of light. Preferably, the multi-component optical channel 1604 is arranged vertically with the light receiving channel 1603, and such a vertical design not only simplifies the design of the optical path, but also can improve the transmission efficiency of the light and the accuracy of the detection. When the light enters from the light receiving channel 1603, it is transmitted through the vertical spectroscopic channel 1604, so that the optical path is short and direct, reducing the light loss, and facilitating the compact integration of the modular structure, which is suitable for the miniaturization requirements of the microfluidic detection equipment. In addition, in this embodiment, the side of the light splitting channel 1604 away from the light receiving channel 1603 is connected to the outside world and is used to install an external light intensity detection device. Through such a design, the external light intensity detection device can be easily installed on the light splitting module 1601, so that the intensity or other optical characteristics of the light after passing through the light splitting channel 1604 can be effectively detected. This part of the design increases the flexibility of the device, so that the detection module can be easily combined with different types of light intensity sensors to meet the needs of different detection scenarios.

[0098] When detecting the optical characteristics of different reaction areas in the microfluidic biochemical reagent disk, the multiple groups of spectroscopic channels 1604 can detect multiple areas at the same time, and each spectroscopic channel 1604 is equipped with a light intensity detection device, so that the optical signals of different areas can be obtained. Since the spectroscopic channel 1604 is perpendicular to the light receiving channel 1603, the reflection and refraction losses in the light transmission process are effectively controlled, ensuring that the intensity of the light signal received by each detection channel is sufficient, thereby improving the accuracy and reliability of the detection results. In this embodiment, by preferably configuring the spectroscopic channels 1604 as multiple groups and adopting a vertical design in the spatial layout, and adding a convenient connection with an external light intensity detection device, it not only improves the optical performance and detection efficiency of the spectroscopic module 1601, but also makes the overall structure more compact and modular, which is adapted to the needs of microfluidic detection equipment for multi-channel efficient detection and miniaturization.

[0099] Example 7

[0100] In this embodiment, the spectroscopic holes 1606 are designed to be multiple groups, and the multiple groups of spectroscopic holes 1606 are respectively arranged on both sides of the spectroscopic channel 1604. Such a design allows the light to be effectively guided to the external light sensor by the multiple spectroscopic holes 1606 after passing through the spectroscopic channel 1604, thereby improving the diversity and accuracy of detection. The spectroscopic holes 1606 are distributed on both sides of the spectroscopic channel 1604, so that the light can be distributed from the spectroscopic channel 1604 to the left and right sides respectively, so as to achieve the optimal utilization of light resources. Preferably, the multiple groups of spectroscopic holes 1606 are sequentially arranged on the upper and lower sides of the spectroscopic channel 1604, and the detection spectroscopic lenses 1607 corresponding to each adjacent spectroscopic hole 1606 are connected end to end in a wave shape. Such a wave-shaped design not only increases the number of spectroscopic holes 1606, but also makes the optical path between each spectroscopic hole 1606 and the corresponding detection spectroscopic lens 1607 more stable and smooth. The wavy connection mode enables the light to be uniformly guided to the light splitting hole 1606 by refraction or reflection after passing through the light splitting channel 1604, while reducing the scattering and loss of the light during the transmission process.

[0101] Specifically, after the light enters the light receiving channel 1603, it is distributed by the channel splitter lens 1605 and transmitted to each splitter channel 1604. The light in the splitter channel 1604 enters the detection system through the splitter holes 1606 set on the upper and lower sides of the splitter channel 1604. The wavy detection splitter lens 1607 design ensures that each splitter hole 1606 can receive a uniform and sufficient intensity light signal, thereby effectively improving the accuracy of the detection data.

[0102] This wavy end-to-end design is particularly suitable for multi-channel, high-precision optical detection requirements. For example, in the detection of microfluidic biochemical reagent disks, the light signals of different reaction areas can be collected and analyzed through these spectroscopic holes 1606. Due to the wavy detection spectroscopic lens 1607 design, each spectroscopic hole 1606 can obtain an effective position in the light path, and the light can be captured by different light intensity sensors after passing through different spectroscopic holes 1606, ensuring that the detection results of each channel have high consistency and reliability. In addition, the wavy design in this embodiment helps to reduce the height and volume of the spectroscopic module 1601, making the structure of the overall device more compact, and facilitating integrated design and integrated installation with the detection system of the microfluidic biochemical reagent disk. The modular design of the spectroscopic hole 1606 is combined with the detection spectroscopic lens 1607, so that the device has a high degree of scalability, and can flexibly increase or decrease the number of spectroscopic holes 1606 according to specific detection requirements, thereby realizing diversified detection of the microfluidic system.

[0103] This embodiment, by setting the spectroscopic holes 1606 into multiple groups and preferably adopting the end-to-end connection design of the wavy detection spectroscopic lens 1607, not only improves the light detection efficiency and accuracy of the spectroscopic module 1601, but also optimizes the structural layout of the overall equipment, further meeting the needs of microfluidic biochemical detection equipment for miniaturization, high efficiency and multi-channel optical detection.

[0104] Example 8

[0105] In this embodiment, the mounting body 1602 is further provided with a mounting hole 1608, and the mounting hole 1608 is connected to the majority of the spectroscopic holes 1606. These mounting holes 1608 are used to provide more light detection paths for the spectroscopic module 1601. By providing the mounting holes 1608, the light can be effectively introduced into the mounting holes 1608 after passing through the spectroscopic holes 1606, thereby further realizing the collection of optical signals. The connection design of the mounting holes 1608 and the majority of the spectroscopic holes 1606 helps to simplify the transmission path of the optical signal, so that the light can reduce the loss during the transmission process and improve the detection efficiency.

[0106] Preferably, a light detection unit 1609 is provided inside the mounting hole 1608, and the light detection unit 1609 is used to directly detect the light entering the mounting hole 1608. This design enables the light detection unit 1609 to be tightly integrated into the mounting hole 1608, reduces possible interference of the light during transmission, and ensures the accuracy of detection. At the same time, the setting of the mounting hole 1608 enables the light detection unit 1609 to be quickly installed or replaced, thereby simplifying the maintenance and upgrade process of the detection device.

[0107] To prevent light from interfering with the detection results, in this embodiment, a light shielding ring 1610 is provided between the light detection unit 1609 and the mounting hole 1608. The light shielding ring 1610 is designed to block stray light from the mounting hole 1608, ensuring that only light passing through the light splitting module can enter the light detection unit 1609. The use of the light shielding ring 1610 effectively improves the reliability of the detection results, reduces the influence of external light sources on the detection, and improves the accuracy of optical detection.

[0108] In addition, in the present embodiment, the installation body 1602 is also provided with an external component 1611, and the external component 1611 is used to connect the light splitting module 1601 to the device body 11. The design of the external component 1611 enables the light splitting module 1601 to be integrated with the device quickly and stably, and a modular installation method is realized. The external component 1611 can adopt a standardized interface form, so that the light splitting module 1601 can be compatible with different types of detection equipment, thereby increasing the wide range of its applications. Through the connection of the external component 1611, the entire light splitting module 1601 can be easily integrated with the main body of the microfluidic biochemical reagent disc detection device 10, which not only improves the convenience of installation and disassembly of the equipment, but also ensures the stability of the equipment during operation.

[0109] For example, in the detection application of microfluidic biochemical reagent disk, after the light passes through the spectroscopic hole 1606, it enters the light detection unit 1609 through the mounting hole 1608, and the light detection unit 1609 collects and analyzes the optical signals of each detection channel. The light shielding ring 1610 effectively prevents the light source from entering, so that the detection results are more accurate and consistent. The external component 1611 can be seamlessly connected with the main structure of the detection equipment to ensure the continuity and stability of the entire detection process.

[0110] This embodiment further enhances the optical detection capability and integration with the device of the spectrometer module 1601 by setting the mounting hole 1608, the light detection unit 1609, the shading ring 1610 and the external component 1611, significantly improves the accuracy of optical detection and the convenience of equipment installation, and is particularly suitable for the needs of multi-channel efficient detection and modular integrated installation of microfluidic biochemical detection equipment.
