Description

Technical Field

[0001] This utility model relates to the technical field of graded processing and testing devices, and in particular to a graded processing and testing device for medical microbial samples. Background Technology

[0002] Different microorganisms require optimal culture environments to promote rapid reproduction. Currently, aerobic microorganisms, such as Escherichia coli, are typically cultured using shake flasks or open media. In shake flask culture, the flask containing the culture medium and inoculum is placed on a shaker, and continuous shaking ensures ample contact between air and the culture medium, providing oxygen for the aerobic microorganisms. Open media culture, on the other hand, exposes the microorganisms directly to air, utilizing atmospheric oxygen to meet their growth needs. However, these methods have drawbacks. The cleanliness of the culture medium cannot be guaranteed during cultivation, and airborne bacteria often settle on the medium and multiply, leading to a non-singular microbial community. For microorganisms undergoing graded cultivation (where contaminating bacteria compete with the target culture and may affect subsequent target bacteria counts), the influence of contaminating bacteria inevitably leads to deviations in subsequent experimental data. Utility Model Content

[0003] This invention provides a medical microbial sample grading and testing device. By placing the culture medium inside the storage space and then filling the storage space with clean air while maintaining a positive pressure inside the storage space, the device can ensure that the storage space is not contaminated by airborne bacteria, thus guaranteeing the accuracy of the experimental results.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0024] First refer to Figures 1-6A medical microbial sample grading and testing device is disclosed. Its main body is a box structure 4, which is divided into multiple independent storage spaces 2. In use, each storage space 2 contains one or more culture media 15. The attached diagram illustrates a space containing one culture media 15. The innovation of this invention lies in the fact that each storage space 2 is equipped with an exhaust port 301 and an air supply pipe 7. Clean air is supplied to the interior of the storage space 2 through the air supply pipe 7, thereby maintaining a positive pressure in the storage space 2 and preventing unclean air from entering and causing contamination of aerobic bacteria during cultivation. Specifically, the clean air source is provided by a gas purification device connected to the input end of the air supply pipe 7, and the directional airflow is powered by a pump 9 installed on the air supply pipe 7. That is, in use, the airflow path is: outside, air purification device, air supply pipe 7, storage space 2, exhaust port 301, and back to the outside. It should be further noted that each storage space 2 is equipped with an opening and closing door 3 to facilitate the retrieval or placement of the culture medium 15. The exhaust vents 301 are preferably located on the two side walls of the storage space 2 opposite to the air supply pipe 7, to ensure the residence time of clean air inside the storage space 2. In the attached diagram, the opening and closing door 3 is located on the front of the storage space 2, the exhaust vent 301 is located on the opening and closing door 3 of the storage space 2, and the output end of the air supply pipe 7 is located on the back of the storage space 2.

[0025] Furthermore, the gas purification device described above is a box 4 with an air inlet 5 on one side. Inside the box 4 is a high-efficiency filter 6. Specifically, the high-efficiency filter 6 is a known filter element that has been used in clean benches. Its detailed structure will not be described here. The high-efficiency filter 6 is used to capture particulate dust, bacteria and various suspended matter of 0.3um and below to ensure the cleanliness of the air. As can be easily seen from the attached diagram, after the external air enters the box 4, it is filtered by the high-efficiency filter 6 and then enters the air supply pipe 7 and flows to the storage space 2.

[0026] Furthermore, the multiple storage spaces 2 inside the incubator 1 can share a single gas purification device, meaning that the input ends of the gas supply pipes 7 corresponding to the multiple storage spaces 2 are all connected to the output end of the gas purification device.

[0027] Furthermore, such as Figure 4 and Figure 7To achieve precise temperature control of the storage space 2, the technical solution provided by this utility model also includes a controller 14, a temperature sensor 22, and a heating wire 8. The temperature sensor 22 is located inside the storage space 2 and is used to monitor the temperature of the storage space 2. The heating wire 8 is located inside the air supply pipe 7 and is used to heat the air flowing inside the air supply pipe 7. The output end of the temperature sensor 22 is connected to the input end of the controller 14 and is used to provide a temperature signal to the controller 14. The output end of the controller 14 is used to issue a control signal, which is used to adjust the heating power of the heating wire 8. When the temperature sensor 22 detects that the internal temperature of the storage space 2 is low (below the set value), the controller 14 controls the heating wire 8 to increase its power, so that the temperature of the air entering the storage space 2 increases. Conversely, when the internal temperature of the storage space 2 is higher than the set value, the controller 14 controls the heating wire 8 to decrease its heating power, so that the temperature of the air entering the storage space 2 decreases, and the internal temperature of the storage space 2 also decreases.

[0028] Furthermore, the storage space 2 is also equipped with a placement platform 11 for placing culture medium 15. When the culture medium 15 is placed on the placement platform 11, it can be positioned closer to the top of the storage space 2. The culture chamber is made of transparent material at least at the top (or the entire chamber can be made of transparent material). The observation device 16 can be used to easily observe the microbial community status inside the storage space 2. The observation device 16 can be driven by a drive component to observe the culture medium 15 inside different storage spaces 2. The specific drive component can be as shown in the attached figure. The drive component includes two opposing upright plates 17, with the two upright plates 17 positioned between each other. A guide rod 18 is fixedly connected, and a threaded rod 19 is rotatably connected to the two upright plates 17. The output end of the threaded rod 19 is equipped with a driving component (which can be a motor 20, hereinafter referred to as motor 20, or other driving components capable of rotating the threaded rod 19). A base 21 is also provided on the guide rod 18 and the threaded rod 19. The guide rod 18 slides through the base 21, and the threaded rod 19 is threadedly engaged with the base 21. When the controller 14 controls the motor 20 to run, the motor 20 drives the threaded rod 19 to rotate, and the base 21 moves horizontally along the guide rod 18. By controlling the rotation direction of the motor 20, the reciprocating movement of the observation device 16 is achieved. The observation device 16 can specifically be a microscope or a magnifying glass. Furthermore, to facilitate the positioning of the observation device 16, the observation position can be controlled by buttons, including buttons for controlling the forward and reverse rotation of the motor 20. Figure 8 The forward rotation button is button 13, and the reverse rotation button is button 23. When the forward rotation button is pressed, the motor 20 will rotate continuously in the forward direction. When the button is released, it will stop. The reverse rotation button works in the same way. This is a common control method and will not be described in detail here.

[0029] Furthermore, each storage space 2 is equipped with a water storage container 12 to ensure sufficient humidity in the storage space 2. The water storage container 12 should contain sterile water.
