Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical testing technology, and in particular to a fluorescence-based multi-channel rapid detection and analysis instrument. Background Technology
[0002] A fluorescence analyzer is an instrument that uses the fluorescence effect of fluorescent substances for detection. Immunochromatographic test strips contain fluorescein, which, after being irradiated by an excitation light source and absorbing incident light of a certain wavelength, emits fluorescence with a wavelength slightly longer than the incident light. Once the light source stops irradiating, the emitted light also disappears. Fluorescein is used as a label to bind to known antibodies without affecting their immunological properties. Then, the fluorescein-labeled antibody is used as a standard reagent to detect and identify unknown antigens. After the antigen and antibody undergo an immune reaction, the distribution of the antigen can be determined through automatic analysis by the analyzer.
[0003] The analytical equipment currently used for fluorescence detection mainly consists of a light source, an optical system, a sample placement area, and a signal processing unit. The light source emits excitation light, which is focused onto the sample by the optical system. The fluorescent substances in the sample are excited and produce fluorescence. The fluorescence signal is collected and transmitted to the signal processing unit for analysis, thereby obtaining the detection result.
[0004] Currently used analyzers place samples directly on a sample tray without proper securing, causing the samples to easily shake during operation. This can lead to sample position shifts during fluorescence detection, preventing the excitation light from accurately targeting the sample and interfering with the collected fluorescence signal. Consequently, detection errors occur, affecting the accuracy and reliability of the detection data. To address these issues, a fluorescence-based multi-channel rapid detection analyzer is proposed. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figures 1-3This utility model provides an embodiment of a fluorescence-based multi-channel rapid detection analyzer, comprising a device body 1, a sample tray 7 slidably connected inside the device body 1, a translation component installed inside the device body 1, and a clamping component installed outside the sample tray 7; the translation component includes an electric push rod 11, which is externally fixedly connected inside the device body 1, and the sample tray 7 is externally fixedly connected to the end of the electric push rod 11. Multiple sample tubes 8 are placed inside the sample tray 7. A fixing block 12 is fixedly connected inside the device body 1, and the sample tray 7 is slidably connected to the outside of the fixing block 12. The electric push rod 11 drives the sample tray 7 to translate, sequentially delivering samples from different sample tubes 8 to the detection area, thereby achieving orderly detection of multi-channel samples. In this way, the analyzer can simultaneously detect multiple samples, greatly improving detection efficiency and saving time and labor costs. A door 5 is rotatably connected to the outside of the device body 1, and a handle 6 is fixedly connected to the outside of the door 5. The main body 1 is externally fixed with a sealing ring 10. Operators can open or close the cabinet door 5 using the handle 6, which can be used for daily maintenance and repair of internal components. During the operation of the analyzer, if dust particles from the external environment enter the analyzer, they will affect the transmission of the optical path and the detection of the optical signal, leading to deviations in the detection results.
[0034] Reference Figure 1 , Figure 2 and Figure 4 The clamping assembly includes a spring rod 13, which is fixedly connected to the inner side of the sample tray 7. A clamping block 14 is fixedly connected to the end of the spring rod 13. During the operation of the analyzer, the spring rod 13 can drive the clamping block 14 to provide sufficient clamping force to the sample tube 8, ensuring the sample remains stable under the influence of these external forces, preventing sample shaking, tipping, or displacement, and ensuring that the detection process is not disturbed by external factors, maintaining the stability of the detection environment. A display screen 3 is fixedly connected to the middle of the device body 1, and operation keys 4 are slidably connected to the middle of the device body 1. A printing port 9 is opened in the middle of the device body 1, and a wiring port 2 is opened on the outside of the device body 1. The wiring port 2 facilitates connection with external devices, enabling data exchange between the analyzer and other devices or systems. Connecting a barcode scanner allows for quick and accurate reading of sample information, improving sample management and detection efficiency.
[0035] Working Principle: The samples to be tested are placed into multiple sample tubes 8, and then the sample tubes 8 are placed inside the sample tray 7. The clamping block 14 at the end of the spring rod 13 on the inner side of the sample tray 7 clamps and fixes the sample tubes 8 under the elastic force of the spring rod 13, ensuring that the sample tubes 8 remain stable during the test and avoiding the influence of shaking or other factors on the test results. The electric push rod 11 is activated, pushing the sample tray 7 to slide along the fixing block 12 inside the device body 1. The electric push rod 11 can precisely control the movement position and distance of the sample tray 7, allowing the sample tubes 8 to move sequentially to the test area, realizing the orderly detection of multi-channel samples. The sealing ring 10 on the outside of the device body 1 helps maintain the stability of the internal environment of the device, preventing external dust, moisture, and other factors from interfering with the test, thus protecting the internal components of the device and ensuring the accuracy of the test.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
