[0001] The utility model relates to the technical field of optical detection, in particular to a spectroscopic module for reagent disc detection. Background Art

[0002] In the field of optical detection, spectroscopic modules are widely used in various detection devices to separate and process light signals of different wavelengths. In the detection scenario of microfluidic biochemical reagent discs, it is necessary to detect the reaction results of different reagents by optical means. However, the existing spectroscopic modules have some design shortcomings. For example, the common spectroscopic modules on the market usually adopt a larger vertical arrangement structure, which takes up more space, resulting in a larger overall size of the equipment, which is not convenient for the miniaturization design and integration of microfluidic detection systems. In addition, some spectroscopic modules use a single set of sensors. This design has limitations in detection and cannot simultaneously and efficiently detect the reaction conditions in multiple microfluidic channels, affecting the accuracy and efficiency of the detection data.

[0003] To meet the testing needs of microfluidic biochemical reagent trays, existing technologies have attempted to improve the structure of spectrometer modules, making them more compact, easier to integrate with microfluidic systems, and flexible enough to achieve higher detection capabilities. However, technical bottlenecks remain, such as the module's relatively large overall size and insufficient functional scalability. Further improvements are urgently needed to meet the requirements of modern microfluidic testing equipment for miniaturization, efficiency, and modular design. Utility Model Content

[0024] Example 1

[0025] See also Figures 1 to 3 , a spectroscopic module 1601 for reagent disc detection proposed in this embodiment includes a mounting body 1602. The mounting body 1602 has a compact structure and is designed to be easily integrated 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 an external light source. A channel spectroscopic lens 1605 is provided at the connection between the light receiving channel 1603 and the spectroscopic channel 1604. The channel spectroscopic lens 1605 is used to reflect the light passing through the light receiving channel 1603 into the spectroscopic channel 1604, thereby achieving effective spectroscopic separation of the light between different channels. In order to achieve diversity and high efficiency in 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, thereby being able to detect the intensity or other characteristics of the light 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.

[0026] In a specific implementation, the mounting body 1602 can adopt 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, split it through the channel spectroscopic lens 1605, and then transmit the light to the corresponding spectroscopic hole 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 through a horizontal arrangement, so that the volume of the entire spectroscopic module 1601 is significantly reduced, which is suitable for the detection scenario of microfluidic biochemical reagent disks. The modular structure not only facilitates installation and disassembly, but also allows the spectrometer module 1601 to be expanded according to specific needs to adapt to the installation requirements of multi-component optical sensors, thereby improving detection efficiency and data accuracy.

[0027] In actual 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. 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 designs the optical spectroscopic module 1601 into a modular and compact structure, which not only achieves efficient detection of multiple channels of the microfluidic biochemical reagent disk, but also improves the miniaturization level of the entire detection system, and is suitable for various application scenarios of miniaturized equipment that require efficient detection.

[0028] Example 2

[0029] In this embodiment, the structure of the spectrometer module 1601 is further optimized to meet the multi-channel detection requirements of the microfluidic biochemical reagent tray. Specifically, this embodiment is based on the basic structure of the first embodiment, and through further optimization design, the detection performance and installation convenience of the spectrometer module 1601 are improved.

[0030] First, the spectroscopic channels 1604 in the spectroscopic module 1601 are arranged into multiple groups, and the multi-component optical channels 1604 are respectively located on both sides of the light receiving channel 1603. This design enables the spectroscopic channels 1604 to receive and disperse the light from the light receiving channel 1603 more evenly, thereby realizing synchronous detection of multiple detection areas in the reagent disc. Each component optical channel 1604 is connected to the light receiving channel 1603, and after receiving the light, it is dispersed into each spectroscopic channel 1604 through the channel spectroscopic lens 1605, realizing multi-directional distribution of light. Preferably, the multi-component optical channel 1604 is arranged perpendicular to the light receiving channel 1603. Such a vertical design not only simplifies the design of the optical path, but also improves the transmission efficiency of the light and the accuracy of the detection. When the light enters the light receiving channel 1603, it is transmitted through the vertical spectroscopic channel 1604, making the optical path short and direct, reducing light loss, and facilitating the compact integration of the modular structure, which is suitable for the miniaturization requirements of microfluidic detection equipment. Furthermore, in this embodiment, the side of the spectroscopic channel 1604, remote from the light receiving channel 1603, is connected to the outside world and is used to mount an external light intensity detection device. This design allows for convenient installation of the external light intensity detection device on the spectroscopic module 1601, effectively detecting the intensity or other optical properties of light passing through the spectroscopic channel 1604. This design enhances the flexibility of the device, allowing the detection module to be easily combined with different types of light intensity sensors to meet the needs of diverse detection scenarios.

[0031] When detecting the optical properties of different reaction areas in a 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 channels 1604 are perpendicular to the light receiving channel 1603, the reflection and refraction losses during 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. This embodiment optimizes the spectroscopic channels 1604 into multiple groups and adopts a vertical design in the spatial layout, while adding a convenient connection with an external light intensity detection device. This 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 suitable for the microfluidic detection equipment for multi-channel efficient detection and miniaturization.

[0032] Example 3

[0033] 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. This 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, realizing 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 wavy shape. Such a wavy 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 light during the transmission process.

[0034] Specifically, after light enters light receiving channel 1603, it is distributed by channel beam splitter lens 1605 and transmitted to each beam splitter channel 1604. Light within beam splitter channel 1604 enters the detection system through beam splitter apertures 1606 located on the upper and lower sides of beam splitter channel 1604. The wavy design of detection beam splitter lens 1607 ensures that each beam splitter aperture 1606 receives a uniform and sufficiently strong light signal, effectively improving the accuracy of the detection data.

[0035] This wavy end-to-end design is suitable for multi-channel, high-precision optical detection needs. For example, in the detection of microfluidic biochemical reagent discs, the light signals of different reaction areas can be collected and analyzed through these spectroscopic holes 1606. Due to the wavy design of the detection spectroscopic lens 1607, each spectroscopic hole 1606 can obtain an effective position in the light path. After the light passes through different spectroscopic holes 1606, it can be captured by different light intensity sensors, ensuring that the detection results of each channel are highly consistent and reliable. 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 convenient for integrated design and integrated installation with the detection system of the microfluidic biochemical reagent disc. The modular design of the spectroscopic holes 1606 combined with the detection spectroscopic lens 1607 makes the device highly scalable and can flexibly increase or decrease the number of spectroscopic holes 1606 according to specific detection needs, thereby realizing diversified detection of the microfluidic system.

[0036] 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.

[0037] Example 4

[0038] In this embodiment, mounting body 1602 further defines mounting holes 1608, which communicate with the majority of spectroscopic holes 1606. These mounting holes 1608 provide more light detection paths for spectroscopic module 1601. The provision of mounting holes 1608 effectively directs light through spectroscopic holes 1606 into mounting holes 1608, further enabling optical signal collection. The connection between mounting holes 1608 and the majority of spectroscopic holes 1606 simplifies the optical signal transmission path, minimizing light loss during transmission and improving detection efficiency.

[0039] 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, reducing possible interference of light during external transmission and ensuring 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. To prevent external 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 outside the mounting hole 1608, ensuring that only light passing through the spectrometer 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 impact of external light sources on the detection, and improves the accuracy of optical detection.

[0040] In addition, in the present embodiment, the mounting body 1602 is further provided with an external component 1611, which is used to connect the spectroscopic module 1601 to the main body of the external device. The design of the external component 1611 enables the spectroscopic module 1601 to be quickly and stably integrated with the external device, thereby realizing a modular installation method. The external component 1611 can adopt a standardized interface form, so that the spectroscopic module 1601 can be compatible with different types of detection equipment, thereby increasing its wide application. Through the connection of the external component 1611, the entire spectroscopic module 1601 can be conveniently integrated with the main body of the microfluidic biochemical reagent disc detection device, which not only improves the convenience of installation and disassembly of the device, but also ensures the stability of the device during operation.

[0041] For example, in microfluidic biochemical reagent tray testing applications, light passes through spectroscopic aperture 1606 and then enters light detection unit 1609 through mounting hole 1608. Light detection unit 1609 collects and analyzes the optical signals from each detection channel. Light shielding ring 1610 effectively prevents external light from entering, resulting in more accurate and consistent test results. External connector 1611 seamlessly integrates with the main structure of the testing device, ensuring continuity and stability throughout the entire testing process.

[0042] This embodiment further enhances the optical detection capability and integration with external devices of the spectrometer module 1601 by providing a mounting hole 1608, a light detection unit 1609, a light shielding ring 1610 and an external component 1611, significantly improves the accuracy of optical detection and the convenience of equipment installation, and is suitable for the needs of multi-channel efficient detection and modular integrated installation of microfluidic biochemical detection equipment.
