[0002] With the development of new technologies, various countries have successively issued some regulations, policies and guiding documents on the sealing requirements of drugs. They all point out that sterile drugs should have intact integrity throughout the entire shelf life of the drug to prevent the invasion of microorganisms.

[0003] At present, pharmaceutical companies test the sealing of medicine bottles based on the characteristics of the medicine bottles and medicines. Some products that are melt-sealed and conductive generally choose high-voltage discharge online to detect the sealing of medicine bottles. Some products that are not suitable for high-voltage discharge do not undergo online sealing tests. Or traditional destructive testing methods are used, and the main methods used are differential pressure color water bathing methods. That is, the sealed medicine bottle is placed in water with a color that is significantly different from that of the medicine, a certain negative pressure is applied, and it is left for a period of time. After that, the medicine bottle is taken out to see if there is colored water entering the medicine bottle to manually determine whether the medicine is leaking.
