[0002] Tuberculosis is still a major global public health problem, which seriously threatens human health. Mycobacterium tuberculosis is the pathogenic bacteria that causes tuberculosis, which has complex biological characteristics and increasingly serious drug resistance, making the treatment of tuberculosis more difficult. Therefore, accurately and quickly detecting the sensitivity of mycobacterium tuberculosis to different anti-tuberculosis drugs is crucial for developing effective treatment programs and controlling the spread of tuberculosis.

[0003] The traditional mycobacterium tuberculosis drug sensitivity test method often has many limitations. In the prior art, mycobacterium tuberculosis is placed on a drug sensitivity plate for culture, and then the drug sensitivity results of mycobacterium tuberculosis are displayed on a display screen in real time. However, during the use of the culture instrument, the drug sensitivity plate needs to be taken out from the culture instrument after each drug sensitivity test. However, when the drug sensitivity plate is taken out, the mycobacterium tuberculosis on the drug sensitivity plate will come into contact with the outside air, which can easily cause the mycobacterium tuberculosis to be released into the air in the laboratory, affecting the health of the test personnel. At the same time, during the drug sensitivity test, some mycobacterium tuberculosis is released into the gas in the culture instrument, and when the culture instrument is opened, the gas containing mycobacterium tuberculosis is quickly released into the outside air, which poses a certain safety hazard.
