AI Technical Summary

Technical Problem

Traditional jet nebulizers are prone to clogging and cannot meet the filtration requirements of different drugs. Furthermore, the integrated connection between the siphon tube and the jet head assembly makes cleaning and disinfection inconvenient and poses a risk of bacterial growth.

Method used

A medical jet nebulizer including a siphon tube and a jet head was designed. The siphon tube has a first filter hole at the liquid inlet end and a second filter hole inside the jet head. The siphon tube is detachably connected to the nebulizer cup. With multiple suction holes and annular protrusion structure, the filtration effect and cleaning convenience are increased.

Benefits of technology

It effectively filters impurities, prevents clogging, improves the purity of the medicine, facilitates cleaning and disinfection, has a wide range of applications, and ensures the stability and flexibility of the atomization process.
