Description

Air tightness leak detection device Technical Field The utility model belongs to the technical field of air tightness leakage detection, and particularly relates to an air tightness leakage detection device. Background In the medical field, many injection molded parts such as infusion bags, respiratory parts, medical plastic ampoules and the like are required to have good air tightness. Because of the particularities of medical instruments, the sterility and dust-free properties make it necessary to ensure a sealed condition during packaging and transport. If the packaging bag or the injection molding piece leaks air, the storage of the internal medicine is not facilitated, and the patient is more easily affected by bacteria when using the medicine, so that medical accidents are caused. Although some airtight leakage detecting devices exist in the current market, the problems of lack of disinfection and sterilization on the device, low detection efficiency, complex operation and the like may exist. For example, some medical packaging bag airtight leakage detecting devices may cause the medical packaging bag to be infected by external bacteria while performing airtight leakage detection.
