Description

Technical Field

[0001] This utility model relates to the field of medical testing technology, and in particular to a fluorescent immunoassay reagent card testing device. Background Technology

[0002] Fluorescence immunoassay (FIA) is a bioassay technique based on fluorescently labeled antigens or antibodies, widely used in medical diagnostics, food safety testing, and environmental monitoring. This technique uses a specific wavelength of light to excite a fluorescently labeled substance and detects the intensity of its emitted fluorescence signal to achieve quantitative or qualitative detection of the target analyte. Due to the high sensitivity and specificity of fluorescence signals, this technique has been widely used in clinical testing and laboratory analysis. Fluorescence immunoassay typically uses a reagent card as the detection carrier. The reagent card contains a fixed antigen or antibody; after the sample is added, the reagent card generates a detectable fluorescence signal through a specific fluorescent labeling reaction. The intensity of the fluorescence signal is related to the concentration of the target analyte; therefore, high-precision detection of the fluorescence signal on the reagent card is required using a fluorescence detection device to obtain accurate results.

[0003] Current fluorescence immunoassay devices generally employ a single-channel or limited-channel design, meaning the device can only process one or a small number of reagent cards at a time. These devices typically include an optical excitation source (such as an LED or laser), a fluorescence detection sensor (such as a CCD or CMOS sensor), a filtering system, and a data analysis module. During the detection process, the reagent card enters the detection area via a transmission mechanism. The optical detection system excites and acquires the fluorescence signal on the reagent card, and then the signal processing unit analyzes the data and outputs the detection results.

[0004] Although existing fluorescence immunoassay devices have played an important role in the field of biological detection, they still suffer from insufficient detection efficiency and stability. Utility Model Content

[0026] In some examples of this invention, the fluorescence detection sensor is electrically connected to a signal processing module, which is used to process the electrical signal output by the fluorescence detection sensor.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0053] The following is for reference. Figures 1-2 According to one possible embodiment of the present invention, a fluorescent immunoassay reagent card detection device is provided, including a protective shell 100, multiple transmission channels 200, an optical component 400, and a driving component 300. The protective shell 100 houses all components and has a reagent card transmission inlet 110 and a transmission outlet 120 to ensure smooth transmission of the reagent cards. The multiple transmission channels 200 are arranged in parallel on the same horizontal plane and communicate with the reagent card transmission inlet 110 and the transmission outlet 120, respectively. The optical component 400 is fixedly disposed inside the protective shell 100 and located directly above the multiple transmission channels 200, enabling simultaneous fluorescence signal detection of multiple reagent cards. The driving component 300 is arranged one-to-one below the transmission channels 200, driving the reagent cards to move along the transmission channels 200.

[0054] Specifically, the device uses a drive assembly 300 to move the reagent card along the transport channel 200. When the reagent card passes the optical assembly 400, the excitation light source 410 of the optical assembly 400 emits excitation light of a specific wavelength to excite the fluorescent marker on the reagent card. The fluorescence detection sensor 420 receives the fluorescence signal and converts it into an electrical signal. Subsequently, the signal processing module 500 processes the acquired signal to obtain the final detection result, which is then displayed through the terminal device 520.

[0055] Furthermore, this device can simultaneously detect multiple reagent cards, improving detection efficiency, and the drive component 300 precisely controls the transmission of reagent cards, ensuring the stability of the detection results. In addition, the optical component 400 optimizes the detection of fluorescence signals, improving detection accuracy. Combined with the signal processing module 500 and the terminal device 520, detection results can be acquired in real time, meeting the needs of rapid detection.

[0056] It is worth noting that the protective housing 100 can be made of different materials, such as metal or high-strength plastic, to meet different requirements such as dustproofing and moisture protection in different application environments. The excitation light source 410 of the optical component 400 can adjust the wavelength according to the characteristics of the detected substance to adapt to different fluorescent markers. At the same time, the drive component 300 can use different types of motors 310, such as servo motors 310 or DC motors 310, to optimize the transfer control of the reagent card.

[0057] Please see Figure 1 , 2 In one possible implementation, the conveying channel 200 includes a guide rail 210, which is fixedly mounted on the bottom 220 of the protective housing 100 and consists of the bottom 220, two side walls 230, and a conveyor belt 240. The bottom 220 supports the reagent cards and is formed by the conveyor belt 240. The two side walls 230 are vertically fixed to both sides of the bottom 220 to define the transmission position of the reagent cards. Both ends of the conveyor belt 240 are connected to the drive assembly 300 to move the reagent cards along the conveying channel 200.

[0058] Specifically, when the drive assembly 300 is started, the conveyor belt 240 drives the reagent card to move along the guide rail 210, ensuring that the reagent card is stably transported along the predetermined trajectory. The two side walls 230 of the guide rail 210 provide lateral constraints to prevent the reagent card from deviating from the track and improve detection accuracy.

[0059] Furthermore, this structure ensures stable transmission of reagent cards, reduces detection errors caused by swaying or offset, and the 240 conveyor belt design facilitates maintenance and replacement, improving the reliability and durability of the equipment.

[0060] It is worth noting that the conveyor belt 240 can be made of different materials, such as silicone or rubber, to adapt to different usage environments. Furthermore, the side wall 230 can be adjusted in height according to the size of the reagent cards to accommodate different sizes of reagent cards.

[0061] Please see Figure 3In one possible implementation, the drive assembly 300 includes a motor 310, a drive wheel 320, a driven wheel 330, and a tensioning structure. The motor 310 is fixedly mounted inside the protective housing 100 to provide transmission power. The drive wheel 320 is connected to the output shaft of the motor 310 and is driven to rotate by the motor 310. The driven wheel 330 is mounted at the end of the conveyor channel 200 and connected to the drive wheel 320 via a conveyor belt 240. The tensioning structure is disposed between the drive wheel 320 and the driven wheel 330 to adjust the tension of the conveyor belt 240, ensuring stable reagent card transmission.

[0062] Specifically, when the motor 310 is running, the drive wheel 320 rotates, driving the conveyor belt 240 to move, thereby propelling the reagent card forward along the conveyor channel 200. The tensioning structure can adjust the tension of the conveyor belt 240 as needed to prevent the reagent card from slipping or getting stuck.

[0063] Furthermore, by rationally designing the drive component 300, the stability and accuracy of reagent card transmission are improved, avoiding detection errors caused by abnormal transmission of reagent cards. Simultaneously, the tensioning structure allows adjustment of the conveyor belt 240's tension, enhancing the system's adaptability. Different types of motors 310 can be used, such as brushless motors or DC geared motors 310, to meet different operational requirements. The tensioning structure can employ spring tensioning or screw adjustment to adapt to different transmission requirements.

[0064] In one possible implementation, the motor 310 is a bidirectional stepper motor 310 capable of controlling the reagent card to move forward or backward along the transport channel 200 so as to transfer it to the recycling area when an abnormal reagent card is detected.

[0065] Specifically, when an abnormal reagent card is detected, the control system will instruct the motor 310 to rotate in the opposite direction, causing the reagent card to move in reverse along the conveyor channel 200 to the recycling area, thereby ensuring that normal reagent cards are detected according to the process and abnormal reagent cards are processed separately.

[0066] Furthermore, this design enhances the intelligence level of the detection system, avoids abnormal reagent cards from affecting subsequent tests, and improves detection efficiency.

[0067] It is worth noting that a servo motor 310 can be used instead of a stepper motor 310 to improve transmission accuracy. Additionally, different collection mechanisms, such as robotic arms or chutes, can be designed for the recycling area to optimize the collection of defective reagent cards.

[0068] Please see Figure 3In one possible implementation, the optical assembly 400 is fixedly mounted on the inner top of the protective housing 100, and includes an excitation light source 410 and a fluorescence detection sensor 420. The excitation light source 410 emits excitation light of a specific wavelength toward the detection area of ​​the delivery channel 200 to excite the fluorescent marker on the reagent card. The fluorescence detection sensor 420 is mounted above the optical path of the excitation light source 410 to receive the fluorescence signal and convert it into an electrical signal.

[0069] Specifically, when the reagent card enters the detection area, the excitation light source 410 emits excitation light, and the fluorescent marker emits fluorescence after being excited. The fluorescence detection sensor 420 receives the fluorescence signal and converts it into an electrical signal for subsequent processing.

[0070] Furthermore, the optical component 400 optimizes the accuracy and sensitivity of fluorescence detection, improves detection stability, and reduces background noise while improving signal quality.

[0071] It is worth noting that the excitation source 410 can use LEDs or lasers of different wavelengths to adapt to different detection needs. The fluorescence detection sensor 420 can be a high-sensitivity photomultiplier tube or a CCD camera to optimize signal acquisition.

[0072] Please see Figure 3 In one possible implementation, the optical component 400 further includes a filter 430 and an optical lens 440. The filter 430 is fixedly mounted in front of the fluorescence detection sensor 420 to block the excitation light, allowing only fluorescence signals of a specific wavelength to pass through, thereby improving detection accuracy. The optical lens 440 is disposed between the filter 430 and the fluorescence detection sensor 420 to focus the fluorescence signal, thereby improving the sensitivity of signal acquisition.

[0073] Specifically, when the fluorescence detection sensor 420 receives a fluorescence signal, the filter 430 blocks the excitation light emitted by the excitation source 410 to reduce background interference and ensure a purer detected fluorescence signal. The optical lens 440 is used to focus the fluorescence signal, improving the sensitivity of signal acquisition and thus ensuring the accuracy of the detection results.

[0074] Furthermore, the selective transmission of filter 430 effectively improves the signal-to-noise ratio of fluorescence detection and reduces misjudgments caused by excitation light interference. The focusing function of optical lens 440 enhances the acquisition efficiency of fluorescence signals, enabling the detection device to more accurately read the fluorescence information on the reagent card.

[0075] It is worth noting that the type of filter 430 can be customized according to the emission wavelength of different fluorescent markers, such as a narrowband filter 430 or a long-pass filter 430, to optimize signal acquisition. The optical lens 440 can adopt different focal lengths or multi-layer coating designs to reduce optical distortion and improve detection accuracy.

[0076] Please see Figure 3 In one possible implementation, the fluorescence detection sensor 420 is electrically connected to the signal processing module 500, which processes the electrical signal output by the fluorescence detection sensor 420.

[0077] Specifically, the fluorescence detection sensor 420 converts the collected fluorescence signal into an electrical signal and transmits it to the signal processing module 500. The signal processing module 500 amplifies, filters, and digitizes the signal, ultimately extracting the valid fluorescence signal data and outputting it to the data processor 510 for analysis.

[0078] Furthermore, the addition of the signal processing module 500 effectively removes noise, optimizes signal quality, and improves detection accuracy. In addition, this module provides real-time signal analysis capabilities, enhancing the intelligence of the detection device.

[0079] It is worth noting that the signal processing module 500 can employ different signal processing algorithms, such as Fourier transform, digital filtering, or machine learning algorithms, to improve data processing capabilities. Simultaneously, it can integrate different analog-to-digital conversion circuits to optimize signal acquisition accuracy.

[0080] Please see Figure 1 , 3 In one possible implementation, the outer surface of the protective housing 100 is provided with indicator lights to indicate whether the conveyor channel 200 is operating normally and whether the optical component 400 is working properly. The indicator lights include a first indicator light 700, a second indicator light 800, and an abnormal alarm indicator light 900.

[0081] The first indicator light 700 is installed at the corresponding position on the conveyor channel 200 to indicate the operating status of the conveyor channel 200. When the conveyor channel 200 is operating normally, the first indicator light 700 will light up; if the conveyor channel 200 malfunctions (such as jamming or failure), the first indicator light 700 will turn off or flash, prompting maintenance personnel to check.

[0082] Specifically, the second indicator light 800 is installed at the corresponding position on the optical component 400 to indicate the working status of the optical component 400. If the optical component 400 is working normally, the second indicator light 800 remains illuminated; if the optical component 400 malfunctions (such as light source attenuation or detector failure), the indicator light turns off or flashes. The fault alarm indicator light 900 will issue an alarm signal, such as a flashing red light or a buzzer alarm, when the equipment detects a fault, reminding the operator to perform maintenance. This indicator light and alarm system provide real-time feedback on the equipment status, enabling operators to promptly identify and resolve potential problems, improving equipment reliability and maintenance efficiency.

[0083] It is worth noting that the indicator lights can use LEDs of different colors to distinguish different fault types; for example, red indicates a serious fault, yellow indicates a warning, and green indicates normal operation. Alarm methods may include audible alarms, vibration alarms, or remote alarm notifications (such as sending warning messages to the operator's mobile phone or computer via Wi-Fi).

[0084] Please see Figure 3 In one possible implementation, the fluorescent immunoassay card detection device further includes a data processor 510, which is fixedly disposed inside the protective housing 100 and connected to the signal processing module 500. The data processor 510 is used to process the fluorescence signal collected by the optical component 400 and send the detection results to the terminal device 520.

[0085] Specifically, the fluorescence signal data processed by the signal processing module 500 is transmitted to the data processor 510. The data processor 510 runs a preset analysis algorithm to calculate and interpret the detection data, ultimately generating a detection result. The detection result can be transmitted to the terminal device 520 via a data cable or a wireless communication module 530 (such as Wi-Fi or Bluetooth).

[0086] Furthermore, the addition of the data processor 510 enables the device to perform data analysis independently without the need for external computer assistance, thereby improving the integration and portability of the detection device. In addition, the wireless transmission function allows for real-time sharing of detection results, improving the convenience of data management.

[0087] It is worth noting that the data processor 510 can employ different architectures, such as ARM architecture microprocessors or FPGA chips, to meet different processing speed requirements. The wireless communication module 530 can use Bluetooth, Wi-Fi, or 5G communication methods to adapt to different data transmission needs.

[0088] Please see Figure 3 In one possible implementation, the terminal device 520 includes a display screen, which is connected to the data processor 510 via a data cable or a wireless communication module 530 and is used to display the detection results in real time.

[0089] The data processor 510 converts the test results into visualized data and transmits it to the terminal device 520 via a data interface. After receiving the test data, the terminal device 520 displays the results through a user interface, including the test curve, fluorescence intensity, and pass / fail determination information.

[0090] Specifically, this design improves the readability of test data, allowing operators to intuitively view the test results. Simultaneously, the test results can be uploaded to a server via cloud storage, enabling remote monitoring and historical data management.

[0091] It is worth noting that the display screen can be LCD, OLED, or e-ink to adapt to different environmental requirements. The terminal device 520 can be expanded to smartphones, tablets, or computers, allowing access to test results via an app or web browser.
