Description

Technical Field

[0001] The present invention relates to the technical field of pathogen detection, and in particular to a rapid detection device for respiratory tract infection pathogens. Background Art

[0002] Respiratory infectious diseases spread pathogenic microorganisms into the surrounding air through exhaled gases, thus completing the transmission process. Respiratory pathogen detection refers to the use of medical detection technology to detect respiratory pathogens that enter the human body. Its purpose is to determine the occurrence and nature of respiratory pathogen infection, provide appropriate treatment plans in the early stages of the disease, and take effective preventive measures to prevent the harm caused by the spread of infection.

[0003] Pathogenic microorganisms enter the human body and multiply in the bronchial mucosal epithelial cells and alveolar epithelial cells in the lungs, eventually invading the lung tissue. The virus is then expelled from the body through exhaled gas, polluting the surrounding air and environment. Many respiratory pathogen antigens are contagious and can easily infect medical staff during the sampling process. Sampling is also troublesome and can easily cause infection to medical staff during the testing process. The protection requirements for testing are relatively high, resulting in a heavy workload for medical staff and a high risk factor at work.

[0004] However, when the existing rapid detection devices for respiratory tract infection pathogens are used, they only detect the wearer's exhaled breath samples and fail to take into account the sampling of pathogens in the ambient air, resulting in an inability to simultaneously assess the patient's risk of environmental pathogen transmission. At the same time, most of the existing equipment do not have an effective airflow guidance design, resulting in airflow dispersion when the patient exhales, and the inability to accurately guide the airflow into the detection area, affecting the detection efficiency. In view of this, a rapid detection device for respiratory tract infection pathogens is provided to overcome the above-mentioned defects. Summary of the Invention

[0025] Working principle: When using the rapid detection device for respiratory tract infection pathogens provided by the present invention, the user first wears the wearing mask 1, and ensures an airtight fit with the face through the flexible silicone fitting ring set on its edge to prevent external air from interfering with sample collection. At the same time, the wearing ear hooks 4 at both ends of the wearing mask 1 are easy to fix and adjust quickly, so that the device can be worn firmly during use to prevent shaking or slipping from affecting the test results. Then the user assembles the mask body 11 and the test box body 2, specifically docking the assembly sleeve 12 in the middle of the mask body 11 with the test box body 2, and inserting it into the mounting shells 31 on both sides of the test box body 2 through the mounting holes 13 at both ends. Under the guidance of the limiting groove 133 and the sliding groove 132, the rapid detection component 3 is accurately slid into position, and the baffle 131 and the sealing gasket 314 fit tightly together to form a sealing structure to block the infiltration of external gas and improve the detection stability and accuracy.

[0026] After assembly is completed, the user exhales slowly through the detection hole 14 at the top of the mask body 11. The exhaled gas forms a directional airflow channel under the guidance of the nose block 15 and the adjustable nose bridge strip provided below it, so that the airflow flows stably and concentratedly into the mounting hole 13. At the same time, the setting of the air inlet and outlet holes realizes a dual-channel flow mode for the sample, ensuring that the sample flows through the detection area and avoiding sample loss or detection interference caused by airflow disturbance. When the exhaled gas enters the detection box body 2, it first passes through the filter block 35 provided on the detection feedback plate 34 to intercept large particles of impurities and suspended matter, ensuring the cleanliness of the downstream reagent area. Then, the pathogen components carried by the gas enter the detection reagent ring 342 area with which it comes into contact. The detection reagent ring 342 contains multiple specific antibody reagents that can develop color after contacting the target pathogen, forming a clear color reaction. At this time, the user observes the feedback through the magnifying lens 32 provided on one side of the mounting shell 31. The lens adopts a 2.5x magnification convex lens structure, and the observation angle can be fine-tuned by the adjustable angle bracket provided around the lens, thereby improving the clarity and convenience of reading.

[0027] At the same time, the rotating ring 331 in the adjustment ring 33 cooperates with the ventilation hole 315 to control the overall air flow rate. The user can adjust the exhalation resistance and flow rate according to the detection requirements to further enhance the personalized use experience. During the entire detection process, the one-way valve 36 is distributed at the air inlet and outlet ends to ensure that the gas flow direction is consistent, effectively preventing the risk of secondary contamination caused by sample backflow and external contaminants. The detection feedback plate 34 remains stable under the positioning of the dual structure of the limiting ring 341 and the barrier ring 317 to avoid detection errors caused by shaking or improper assembly. After the test is completed, the user can quickly disassemble the internal structure of the component by rotating the rotating cover 37 to complete the reagent ring replacement or overall cleaning operation. The vent hole 373 on the rotating cover 37 combined with the one-way valve 36 further realizes internal air pressure regulation and residual gas emission control, thereby improving operational safety and environmental adaptability.
