Description

Technical Field

[0001] This utility model relates to the technical field of ampoule testing equipment, and in particular to an ampoule top air detection device. Background Technology

[0002] When using ampoules to fill liquid medications, a protective gas (e.g., nitrogen) is usually filled into the ampoules to protect the medication. For large quantities of finished ampoules, batch gas detection is often required. The traditional method involves placing the ampoules underwater, crushing them with long pliers, collecting the gas using a gas collection device, and finally conducting the detection. This method is prone to gas leakage, reducing detection accuracy. Furthermore, relying solely on manual crushing-collection-detection is inefficient and unsuitable for large-scale testing.
