In mesh nebulizers, specially shaped piezo rings act as ultrasonic transducers and excite a metal membrane, which has several thousands of holes, to high-frequency vibrations. These vibrations produce particularly homogenous aerosols without heating up the medication. In the process, the protein structure of the modern drugs, which are sometimes very complex, are only subjected to low shear forces since they pass the membrane only once during atomization. Therefore, these macromolecules retain their biological activity and so give access to innovative therapy concepts.
Mesh nebulizers require far less time to atomize medication than conventional systems. The high-frequency operation is noiseless for humans and the low energy requirement of the piezo components enables their use in battery-powered inhalation devices. This means an increase in quality of life, especially for patients with chronic respiratory diseases who have to inhale frequently. Piezoceramic components also master the special hygiene requirements that medical technology brings with it – piezoelectric aerosol generators are suitable for professional cleaning.
