Description
Technical Field
[0001] This utility model relates to the field of microbial detection technology, and in particular to a bacterial drug resistance comparison test device that is easy to clean. Background Technology
[0002] In bacterial resistance testing experiments, it is necessary to strictly ensure that different bacterial species are in the same temperature, humidity and airflow environment to achieve accurate comparison. However, existing testing devices often have environmental control defects: the temperature and humidity inside traditional incubators are prone to local differences, and the containers for containing bacteria are mostly fixed integrated structures. When multiple bacterial species are cultured, the environmental conditions are easily inconsistent due to different placement positions, which directly affects the accuracy of the resistance comparison data.
[0003] Meanwhile, the post-experiment cleaning and sterilization process is cumbersome: the culture containers in existing devices are mostly non-disassemblyable, making them prone to splashing and contamination when waste liquid is poured out; cleaning the inner walls of the containers is difficult and contaminants are easily left behind; sterilization requires transferring the culture components to an external autoclave, which not only increases the number of steps involved but also increases the risk of secondary contamination. In addition, some devices lack convenient observation and retrieval structures, making it easy to disrupt the stable environment inside the chamber when observing the state of the bacteria or retrieving the culture components during the experiment, further affecting experimental efficiency and the reliability of the results. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and propose an easy-to-clean bacterial drug resistance comparison testing device. At the same time, multiple sets of containers are equipped with detachable inner liner and placed on the shelf to ensure that different bacterial species are tested for drug resistance under the same environment. After the experiment, the culture cap can be removed so that the inner liner can be taken out separately, turned over for cleaning or directly replaced.
[0005] To achieve the above objectives, the present invention provides the following technical solution: A bacterial resistance comparison testing device that is easy to clean includes a support box, a shelf inside the support box, multiple containers on the upper left and right sides of the shelf, an inner liner inside each container, a culture cap on the upper end of each container, a rubber stopper at the front end of the culture cap, wing plates on both the left and right ends of the shelf, a support box surrounding the shelf, a ventilation hole at the lower end of the support box, a housing surrounding the support box, an exhaust port on the right end of the housing, multiple sealed doors at the front end of the housing, a water utilization component at the rear end of the housing, an air intake on the right side of the rear end of the housing, a heating air duct inside the rear end of the housing, an exhaust port on the lower front side of the lower end of the heating air duct, and the exhaust port is located on the lower right side of the housing.
[0006] Furthermore, the water utilization component includes a heating water tank located on the right side of the rear end of the housing, a steam duct located on the left end of the heating water tank, and an exhaust port located at the lower front end of the steam duct.
[0007] Furthermore, the steam duct is located in the middle of the rear end of the housing, and the exhaust port is located on the lower left side of the inner side of the housing.
[0008] Furthermore, multiple support rods are provided on the inner sides of both the left and right ends of the box, and the lower ends of both the left and right ends of the support box are tightly attached to the upper side of the support rods.
[0009] Furthermore, a fan is installed at the front right side of the housing, and the fan is installed at the right end of the second exhaust port.
[0010] Furthermore, a viewing window is provided in the middle of the sealed closing door, and an exhaust hole is provided on the upper left side of the left end of the sealed closing door.
[0011] Furthermore, a control panel is provided on the right end of the enclosure.
[0012] Furthermore, a water inlet is provided at the right end of the box.
[0013] This utility model has the following beneficial effects: 1. In this utility model, a stable culture environment is formed on the right side of the chamber by heating the air duct, fan and exhaust port 2 and exhaust port 3. At the same time, multiple sets of containers and inner liner are placed on the shelf to ensure that different strains of bacteria are tested for drug resistance under the same environment. After the experiment is completed, the support box only needs to be transferred to the left side of the chamber to start the high-pressure steam sterilization program.
[0014] 2. In this utility model, a detachable inner liner is installed on the inside of the container. After the experiment, the waste liquid can be safely poured out by opening the rubber stopper. The inner liner can be taken out separately for cleaning or direct replacement by removing the culture cap.

The heating air duct 10 is set as a curved air duct to allow the cold air in the heating air duct 10 to fully exchange heat with the hot water in the heating water tank 13. The hot air is heated by the heating water tank 13 and enters the inner side of the right end of the box 1 through the exhaust port 3 11. The cold air is discharged through the fan 20 through the exhaust port 2 4, so that the temperature of the right end of the box 1 is maintained at the bacterial culture temperature.
[0020] Inoculation and drug sensitivity testing are performed inside the inner liner 16. The rubber stopper 8 is installed on the upper front end of the culture cap 7, and the culture cap 7 is installed on the upper end of the container 15. The container 15 is placed on the upper end of the placement plate 6, and multiple sets of placement plates 6 are placed inside the support box 5. The support box 5 is placed inside the right end of the box 1. The air inside the box 1 flows around the container 15 through the ventilation hole 17. During the culture process, the bacterial culture inside the inner liner 16 can be observed through the viewing window 22 at the front end of the sealed closed door 23. The inner liner 16 is installed inside the container 15. After the experiment, the waste liquid can be safely poured out by opening the rubber stopper 8. The inner liner 16 can be removed and turned over for cleaning or directly replaced by removing the culture cap 7. At the same time, the placement plate 6 can be quickly pulled out from the support box 5 through the wing plate 14, which facilitates all-round cleaning of the bottom of the container 15 and the inside of the support box 5.

After sterilization, open the exhaust port 21, wait for the temperature on the inner left side of the chamber 1 to drop, then take out the support box 5 and remove the container 15. Open the rubber stopper 8 to pour out the liquid in the inner liner 16 to prevent splashing. After pouring out the liquid, open the culture cap 7 to remove the inner liner 16, and turn the inner liner 16 over for cleaning or replacement.
[0023] The shelf 6 can be removed from the support box 5 via the wing plate 14 for easy observation of different groups of bacteria comparison experiments. Through the synergistic effect of the heating air duct 10, the fan 20 and the exhaust port 4 and exhaust port 3 11, a stable and uniform bacterial culture temperature environment is formed at the right end of the chamber 1. At the same time, multiple sets of containers 15 and inner liner 16 are placed on the shelf 6 to ensure that different bacterial species are subjected to drug resistance experiments under the same temperature, humidity and airflow conditions.
