Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of optical detection, and in particular to a reagent disc detection device. BACKGROUND

[0002] With the development of detection technology in the fields of biomedicine and chemistry, reagent detection devices have been widely used in medical diagnosis, environmental monitoring and other fields. The detection of microfluidic biochemical reagent discs requires efficient and accurate analysis of reagent reaction results, which makes the light splitting module play an important role in optical detection. However, the existing light splitting module has some deficiencies in design and application, mainly including the following aspects:

[0003] 1. Large equipment volume, lack of integration, most of the existing light splitting modules adopt a large vertical arrangement structure, which occupies a lot of equipment space, and cannot well meet the miniaturization and integration requirements of microfluidic detection systems. This design limits the application of detection equipment in laboratories, especially small laboratories with limited space;

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

[0005] 3. Insufficient automation level, complex operation, the existing detection equipment usually needs to manually install and disassemble the reagent disc. This method not only has complex operation, but also easily introduces human error, which reduces the detection efficiency and the accuracy of data. In addition, the operation of the equipment in the detection process is not flexible enough for the in-out warehouse, which is difficult to adapt to the detection needs of reagent discs of different specifications.

The drive assembly 1404 is connected with the support frame. The limiting structure 1401 is connected with the equipment main body 11.

The position sensor 1403 is used to detect the extension and retraction stroke of the limiting rod 1406, so as to ensure that the in-out magazine support frame 1402 can be detected in time when it is extended and retracted to the position each time. This helps the detection device to calibrate the position of the reagent disc 1502, and avoids inaccurate installation position of the reagent disc 1502 to cause inaccurate detection result. The driving assembly 1404 is connected with the external magnetic mounting assembly 1500, and the magnetic mounting assembly 1500 includes a magnetic mounting seat 1501 for mounting the external reagent disc 1502.

The cooperation of the limiting structure 1401, the position sensor 1403 and the driving assembly 1404 makes the extension process of the support frame accurately controllable, thereby improving the detection efficiency while ensuring the safety and accuracy of the detection process.

[0080] Embodiment 4

[0081] In this embodiment, based on the basic design in Embodiment 1 and Embodiment 2, the in-out warehouse assembly 1400 is further optimized, especially the puncture structure 1508, the clamping structure of the accommodating cavity 1507, and the anti-rotation and fixing function of the magnetic mounting seat 1501 are improved to further improve the stability and reliability of the assembly in the detection process of the reagent disc 1502. The puncture structure 1508 includes a puncture blade 1532 and a bearing wall 1533 arranged on both sides of the puncture blade 1532. The main function of the puncture blade 1532 is to pierce the sealing film 1511 of the dilution box 1509 to make the dilution liquid enter the inside of the disc body 1503, and the bearing wall 1533 plays a stabilizing and supporting role in the piercing process to prevent the puncture blade 1532 from deviating during piercing.

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

[0083] The outer periphery of the liquid inlet 1506 is provided with a surrounding wall, and the top surface of the surrounding wall is in the same plane as the top of the bearing wall 1533 to provide balanced support and stability. The surrounding wall is also provided with a liquid inlet channel 1537, which is connected with the dilution liquid channel 1534. This design helps the liquid to enter the inside of the disc body 1503 quickly and smoothly after piercing the sealing film 1511, avoiding the situation of liquid overflow and detection interruption.

[0084] Inside the accommodating cavity 1507, a plurality of clamping tables 1538 are arranged, the top of the clamping table 1538 is provided with an opening and closing groove 1539, and the outer periphery of the magnetic sheet 1510 is provided with clamping and protrusions 1540 matched with the clamping table 1538, which are matched with the opening and closing groove 1539.

[0085] The installation channel is formed between the plurality of clamping platforms 1538, which is used to guide the clamping and rotation of the magnetic sheet 1510 through the installation channel and into the opening and closing slot 1539. This design ensures the stability of the magnetic sheet 1510 in the accommodation cavity 1507, preventing dislocation of the magnetic sheet 1510 due to vibration and other factors during operation. The magnetic sheet 1510 is provided with one or more sets of limiting holes 1541 around the outer periphery of the through hole 1512. When subjected to external force, the limiting holes 1541 can rotate and be clamped into the opening and closing slot 1539. This limiting design increases the clamping firmness of the magnetic sheet 1510 and the accommodation cavity 1507 by adding additional fixing points, ensuring that the magnetic sheet 1510 does not shift during detection, further improving the overall reliability of the device.

[0086] The inner walls of the plurality of clamping platforms 1538 form an inner clamping wall mechanism 1542. The inner clamping 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 installation, reduce installation errors, and improve overall detection accuracy. An arc-shaped guide structure 1543 is designed at the bottom of the clamping platform 1538. This arc-shaped design plays a guiding role during installation, making the clamping process smoother and effectively reducing component wear or failure caused by inaccurate clamping.

[0087] To ensure the stability of the mounting seat 1504 and the magnetic mounting seat 1501 when combined, the bottom outer periphery of the mounting seat 1504 is provided with an anti-rotation structure 1544, which can effectively prevent the mounting seat 1504 from rotating during detection due to external forces. Rotation prevention is crucial for ensuring the positioning of the reagent disc 1502, as even slight rotation can lead to inaccurate detection results. The mounting seat 1504 also has a plurality of fixing holes 1545, which are used to connect with the magnetic mounting seat 1501 during installation. These fixing holes 1545 can be used with fixing bolts to securely combine the mounting seat 1504 and the magnetic mounting seat 1501, ensuring the stability of the entire assembly during detection and preventing loosening due to vibration or improper operation.

[0088] The magnetic sheet 1510 is preferably made of iron, which ensures good adhesion between the magnetic sheet 1510 and the magnetic mounting seat 1501, and can be stably clamped onto the protruding structure 1521 of the magnetic mounting seat 1501 under the action of the magnet 1520. During detection, the magnetic sheet 1510 can effectively fix the dilution box 1509 at a predetermined position, avoiding displacement of the dilution box 1509 due to liquid movement or external forces.

[0089] A plurality of positioning holes 1531 are formed on the inner wall of the positioning structure 1515, which are in communication with the annular mounting cavity 1517, and can ensure accurate alignment of the reagent disc 1502 during installation. The air pressure balance groove 1529 is formed at the connection of the straight surface structure 1527, which is used to balance the air pressure change inside the accommodation cavity 1507 during installation, avoid the difficulty of assembly caused by air pressure difference, and ensure that the installation of the reagent disc 1502 can be successfully completed under any conditions.

[0090] In this embodiment, the height of the guide structure 1516 is preferably greater than the height of the positioning structure 1515, and the top outer peripheral edge is provided with an arc-shaped guide surface 1530. Such design helps to smoothly guide the reagent disc 1502 into the correct position during installation, reduces errors and jamming, and improves the efficiency and success rate of pre-detection installation. Through further improvement of this embodiment, the adaptability of the whole in-out magazine assembly 1400 in detection of different specifications of reagent discs 1502 has been significantly improved. The limiting design of the puncture structure 1508 and the magnetic sheet 1510, the clamping mechanism of the accommodation cavity 1507, and the optimization of the anti-rotation and fixing structure make the whole detection process not only more stable and reliable, but also more simple and efficient, which is helpful for the flexible application of different specifications of reagent discs 1502 in the laboratory and efficient operation in the detection process.

[0091] Embodiment 5

[0092] On the basis of the first embodiment, the present embodiment proposes a light splitting module 1601 for reagent disc detection, which comprises a mounting body 1602. The mounting body 1602 is compact in structure and designed to facilitate integration with a microfluidic biochemical reagent disc. The mounting body 1602 is provided with a light receiving channel 1603 and a plurality of light splitting channels 1604 intersecting the light receiving channel 1603. The light receiving channel 1603 is used to receive light from a light source, and the connection between the light receiving channel 1603 and the light splitting channel 1604 is provided with a channel light splitting lens 1605, which is used to reflect the light passing through the light receiving channel 1603 into the light splitting channel 1604, thereby achieving effective light splitting between different channels. In order to realize the diversity and efficiency of detection, the mounting body 1602 is also provided with a plurality of light splitting holes 1606. Each light splitting hole 1606 is used to connect with an external light sensor, which can detect the light intensity or other characteristics after light splitting. The light splitting hole 1606 is in communication with the light splitting channel 1604, and the connection between the light splitting channel 1604 and the light splitting hole 1606 is provided with a detection light splitting lens 1607, which is used to reflect the light in the light splitting channel 1604 into the light splitting hole 1606, ensuring that the light can be accurately received and measured by the sensor.

[0093] In a specific implementation, the installation body 1602 adopts a modular design, and the number of light splitting channels 1604 and light splitting holes 1606 can be flexibly increased or reduced to adapt to different detection requirements. The light receiving channel 1603 can receive light from multiple angles, accurately split the light through the channel light splitting lens 1605, and then transmit the light to the corresponding light splitting hole 1606 through the multiple light splitting channels 1604. The arrangement of the detection light splitting lens 1607 ensures that each light splitting hole 1606 can obtain accurate split light and transmit it to the corresponding light sensor. The design of the light splitting module 1601 also considers the miniaturization requirement of the overall device, and tightly integrates the light receiving channel 1603, the light splitting channel 1604 and the light splitting hole 1606 through a transverse arrangement, so that the volume of the entire light splitting module 1601 is significantly reduced, which is very suitable for the detection scene of the microfluidic biochemical reagent disc. The modular structure not only facilitates installation and disassembly, but also enables the light splitting module 1601 to be expanded according to specific requirements to adapt to the installation requirements of multiple light splitting lenses, improve the detection efficiency and the accuracy of data.

[0094] In actual application, the light receiving channel 1603 can select specific wavelength light into the light splitting module 1601 by setting different optical filters. After the light passes through the channel light splitting lens 1605, it is distributed to different light splitting channels 1604, each light splitting channel 1604 is connected with different detection light splitting lenses 1607 and light splitting holes 1606, so that the optical properties of different reaction regions in the microfluidic biochemical reagent disc can be detected. Through this design, synchronous detection of multiple biochemical indicators in the microfluidic reaction process can be realized, improving the detection efficiency and accuracy. In this embodiment, the optical light splitting module 1601 is designed as a modular and compact structure, which not only realizes efficient detection of multiple channels of the microfluidic biochemical reagent disc, but also improves the miniaturization level of the entire detection system, which is suitable for various miniaturized equipment application scenarios that require efficient detection.

[0095] Embodiment 6

[0096] Based on the embodiment 1. In this embodiment, the structure of the light splitting module 1601 is further optimized to adapt to the multi-channel detection requirements of the microfluidic biochemical reagent disc. Specifically, based on the basic structure of the independent power requirement, this embodiment further optimizes the design to improve the detection performance of the light splitting module 1601 and the convenience of installation.

[0097] Firstly, the light splitting channels 1604 in the light splitting module 1601 are arranged in multiple groups, and the multiple groups of light splitting channels 1604 are respectively located on both sides of the light receiving channel 1603. Such a design enables the light splitting channels 1604 to more evenly receive and disperse the light from the light receiving channel 1603, thereby achieving synchronous detection of multiple detection regions in the reagent disc. Each group of light splitting channels 1604 is connected with the light receiving channel 1603, and the light is dispersed into each light splitting channel 1604 after being received by the channel light splitting lens 1605, thereby achieving multi-directional distribution of light. Preferably, the multiple groups of light splitting channels 1604 are arranged vertically with the light receiving channel 1603. Such a vertical design not only simplifies the design of the light path, but also improves the transmission efficiency of light and the accuracy of detection. When the light enters from the light receiving channel 1603, it is transmitted through the vertical light splitting channels 1604, so that the light path is short and direct, reducing light loss, and facilitating the compact integration of the modular structure, which is suitable for the miniaturization requirement of the microfluidic detection device. In addition, in this embodiment, the side of the light splitting channel 1604 away from the light receiving channel 1603 is connected with the outside and is used for installing an external light intensity detection device. Through such a design, the external light intensity detection device can be conveniently installed on the light splitting module 1601, thereby effectively detecting the intensity or other optical properties of the light after passing through the light splitting channel 1604. 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, thereby meeting the needs in different detection scenarios.

[0098] When detecting the optical properties of different reaction regions in the microfluidic biochemical reagent disc, the multiple groups of light splitting channels 1604 can simultaneously detect multiple regions, and each light splitting channel 1604 is equipped with a light intensity detection device, thereby obtaining the optical signals of different regions. Since the light splitting channels 1604 are perpendicular to the light receiving channel 1603, the reflection and refraction loss in the light transmission process is 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, the light splitting channels 1604 are preferably arranged in multiple groups, and the vertical design is adopted in the spatial layout, and the convenient connection with the external light intensity detection device is also increased, which not only improves the optical performance and detection efficiency of the light splitting module 1601, but also makes the overall structure more compact and modular, thereby meeting the requirements of multi-channel high-efficiency detection and miniaturization of the microfluidic detection device.

[0099] Embodiment 7

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

[0101] Specifically, when the light enters the light receiving channel 1603, it is distributed by the channel light splitting lens 1605 and transmitted into each light splitting channel 1604. The light in the light splitting channel 1604 enters the detection system through the light splitting holes 1606 arranged on the upper and lower sides of the light splitting channel 1604. The wave-shaped detection light splitting lens 1607 design ensures that each light splitting hole 1606 can receive uniform and sufficient intensity of light signal, thereby effectively improving the accuracy of detection data.

[0102] Such a wave-shaped connection design is particularly suitable for multi-channel and high-precision optical detection requirements. For example, in the detection of a microfluidic biochemical reagent disc, the light signals of different reaction regions can be collected and analyzed through these light splitting holes 1606. Due to the wave-shaped detection light splitting lens 1607 design, each light splitting hole 1606 can effectively position in the light path, and the light after passing through different light splitting holes 1606 can be captured by different light intensity sensors, ensuring that the detection results of each channel have high consistency and reliability. In addition, the wave-shaped design in the embodiment helps to reduce the height and volume of the light splitting module 1601, making the overall device structure more compact, and facilitating integrated design and installation with the detection system of the microfluidic biochemical reagent disc. The modular design of the light splitting holes 1606 combined with the detection light splitting lens 1607 makes the device have high scalability, and the number of light splitting holes 1606 can be flexibly increased or decreased according to specific detection requirements, thereby realizing diversified detection of the microfluidic system.

[0103] The embodiment sets the light splitting holes 1606 as multiple groups, and preferably adopts a wave-shaped detection light splitting lens 1607 with a head-tail connection design, which not only improves the light detection efficiency and accuracy of the light splitting module 1601, but also optimizes the overall device structure layout, further meeting the needs of miniaturization, high efficiency and multi-channel optical detection of microfluidic biochemical detection devices.

[0104] Embodiment 8

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

[0106] Preferably, the mounting holes 1608 are provided with light detection units 1609 inside, which are used to directly detect the light entering the mounting holes 1608. This design enables the light detection unit 1609 to be closely integrated in the mounting hole 1608, reducing the possible interference of the light during transmission and ensuring the accuracy of the 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 upgrading process of the detection device.

[0107] To prevent light interference 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 design of the light shielding ring 1610 is used to block the stray light of the mounting hole 1608, ensuring that only the 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, the mounting body 1602 in the embodiment is also provided with an external connecting piece 1611 for connecting the light splitting module 1601 with the device body 11. The design of the external connecting piece 1611 enables the light splitting module 1601 to be quickly and stably integrated with the device, realizing a modular installation mode. The external connecting piece 1611 can adopt a standardized interface form, so that the light splitting module 1601 can be compatible with different types of detection devices, thereby increasing the universality of its application. Through the connection of the external connecting piece 1611, the entire light splitting module 1601 can be conveniently integrated with the main body part of the microfluidic biochemical reagent disc detection device 10, which not only improves the installation and disassembly convenience of the device, but also ensures the stability of the device during operation.

[0109] For example, in the detection application of the microfluidic biochemical reagent disc, after the light passes through the light splitting hole 1606, it enters the light detection unit 1609 through the mounting hole 1608, and the optical signals of each detection channel are collected and analyzed by the light detection unit 1609. The light shielding ring 1610 effectively prevents the light source from entering, so that the detection result is more accurate and consistent. The external connecting piece 1611 can be seamlessly connected with the main structure of the detection device, ensuring the continuity and stability of the entire detection process.

[0110] The embodiment further enhances the optical detection capability of the light splitting module 1601 and the integration with the device by providing the mounting hole 1608, the light detection unit 1609, the light shielding ring 1610 and the external connecting piece 1611, significantly improving the optical detection accuracy and the installation convenience of the device, and is particularly suitable for the multi-channel efficient detection and modular integrated installation requirements of the microfluidic biochemical detection device.
