Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically a disease pathogen sample collection device. Background Technology

[0002] In the crucial stages of disease prevention and control research, accurate pathogen sample collection is the cornerstone of scientific decision-making and precise prevention and control. Traditional collection tools, limited by structural design and material technology bottlenecks, suffer from multiple drawbacks, including cumbersome operation procedures, high risk of cross-contamination, and poor adaptability to extreme environments. In emergency response scenarios of public health emergencies, traditional tools cannot meet biosafety protection requirements. Furthermore, their inadequacy in collecting samples from diverse pathogens, such as those from the respiratory and digestive tracts, is becoming increasingly apparent. For example, during traditional throat swab sampling, medical personnel must repeatedly adjust the angle to ensure effective sample collection, which not only prolongs the operation time but also increases the risk of exposure. Cotton swabs used for environmental sample collection are prone to degradation or compositional changes in complex environments such as humidity and high temperatures. In addition, traditional tools lack intelligent identification and quality monitoring functions, making it difficult to assess the integrity and effectiveness of sample collection in real time. These technological shortcomings severely restrict the timeliness and accuracy of pathogen detection, necessitating technological innovation to achieve intelligent, standardized, and safe upgrades in pathogen sample collection.

[0003] Existing pathogen sample collection devices lack a disinfection and sterilization mechanism for test tube storage boxes. As an important space for temporary sample storage, the test tube storage box is prone to contamination from pathogenic microorganisms, sample debris, and other pollutants on its inner walls and in the gaps between partitions during repeated use. If not disinfected in time, samples placed in the box later may be cross-contaminated due to contact with the contaminant, resulting in the introduction of non-target pathogens or interfering substances into the sample, which seriously affects the accuracy and reliability of subsequent pathogen detection.

[0007] As a further embodiment of this utility model: a disinfection box is fixedly installed inside the box body, the output end of the water pump is connected to the disinfection box through a connecting pipe, the outer surface of the disinfection box is provided with scale markings, and the upper surface of the disinfection box is fixedly installed with a liquid inlet pipe.

[0008] As a further improvement of this utility model: a mounting bracket is fixedly installed inside the housing, and a test tube frame is slidably connected inside the mounting bracket, with the test tube frame located below the nozzle.

[0009] As a further embodiment of this utility model: a water collection box is provided inside the box, a pulley is installed on the bottom surface of the water collection box, a sliding groove is opened inside the box, and the pulley is slidably connected inside the sliding groove.

[0010] As a further embodiment of this utility model: a fixing frame is fixedly installed on the upper surface of the base, a push handle is fixedly installed on the outer surface of the fixing frame, and an anti-slip pad is sleeved on the outer surface of the push handle.

[0012] Compared with the prior art, the beneficial effects of this utility model include:

[0013] This invention utilizes a motor to drive a threaded rod to rotate at a constant speed. With the cooperation of a limiting block and a limiting groove, a guiding and constraining structure is formed, allowing the threaded sleeve to move smoothly and linearly along the axial direction. This, in turn, drives the connecting block and the nozzle mounted on it to reciprocate. When the nozzle moves back and forth inside the test tube storage box, the disinfectant droplets it sprays can evenly cover every corner inside the box. Whether it is an uneven inner wall surface or a narrow and deep partition gap, disinfection can be achieved without dead angles. This dynamic disinfection method effectively avoids the residue of pathogenic microorganisms, sample debris, and other contaminants inside the box, eliminating the risk of cross-contamination of subsequent samples due to contact with contaminants from the source.

[0023] In this embodiment, a connecting block 6 is fixedly installed on the outer surface of the limiting block 308, a nozzle 7 is fixedly installed on the bottom surface of the connecting block 6, and a hose 8 is fixedly connected to the outer surface of the connecting block 6. One end of the hose 8 passes through the connecting block 6 and is connected to the nozzle 7, and the other end passes through the inner wall of the housing 2 and is connected to the output end of the water pump 9.

[0024] In this embodiment, a disinfection tank 10 is fixedly installed inside the tank 2. The output end of the water pump 9 is connected to the disinfection tank 10 through a connecting pipe. The outer surface of the disinfection tank 10 is provided with a scale pattern 12. An inlet pipe 11 is fixedly installed on the upper surface of the disinfection tank 10. The scale pattern 12 can display the water level change in real time.

[0025] In this embodiment, a mounting bracket 4 is fixedly installed inside the housing 2, and a test tube frame 5 is slidably connected inside the mounting bracket 4. The test tube frame 5 is located below the nozzle 7.

[0026] In this embodiment, a water collection box 13 is provided inside the box 2. A pulley 14 is installed on the bottom surface of the water collection box 13. A sliding groove 15 is opened inside the box 2. The pulley 14 is slidably connected inside the sliding groove 15, which facilitates the processing of liquid inside the water collection box 13 and makes it convenient to extract and install.

[0027] In this embodiment, a fixing frame 16 is fixedly installed on the upper surface of the base 1, a push handle 17 is fixedly installed on the outer surface of the fixing frame 16, and an anti-slip pad 18 is sleeved on the outer surface of the push handle 17.

[0028] In this embodiment, the base 1 has an energy storage compartment 19 inside, and a battery 20 is installed inside the energy storage compartment 19.

[0029] Working Principle: In use, first, the test tube frame 5 is removed via the mounting bracket 4. The collected pathogen samples are then placed into the test tubes and positioned within the frame 5. The mounting bracket 4 then moves the test tube frame 5 into the test tube storage area to prevent damage to the test tubes. When disinfection of the test tube storage box is required, the motor 302 is started via the controller 22. The motor 302 drives the threaded rod 304 to rotate at a constant speed. Under the guiding constraint of the limiting block 308 and the limiting groove 309, the threaded sleeve 307 can move smoothly and linearly along the axial direction, thereby driving the connecting block 6 and the nozzle 7 mounted on it to reciprocate. When the nozzle 7 moves back and forth within the test tube storage box, the water pump 9 is started via the controller 22 to pump disinfectant from the disinfection tank 10. The graduated markings on the surface of the disinfection tank 10 display the water level changes in real time, reminding users to replenish the water promptly. The disinfectant mist sprayed from nozzle 7 can evenly cover every corner of the interior of the chamber 2, achieving thorough disinfection even on uneven inner walls and in narrow, deep crevices. Furthermore, the water collection box 13 collects and processes the disinfected liquid, further improving disinfection efficiency and effectively reducing the risk of non-target pathogens or interfering substances contaminating samples. This ensures the accuracy and reliability of subsequent pathogen detection results, making it particularly suitable for the safe storage of highly pathogenic microorganism samples.

Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
