Piezoceramics from CeramTec nebulizing liquid medicine in lung ventilators

Ventilators are lifesavers for many critically ill patients and are now in the news daily in the fight against the COVID-19 virus. The extremely increasing number of intensive care patients fighting for their lives against this virus with ventilators has made these devices a very scarce commodity and poses great challenges for manufacturers to produce and provide additional devices as quickly as possible.

In addition to the actual ventilation, the simultaneous medication of the patient also plays a central role. In the recent past, there has been a move towards atomising or nebulising liquid medication during delivery. Due to the good pulmonary mobility of the atomised particles, the effectiveness of the administered medication is significantly increased compared to conventional dosing methods. Piezoceramic components from CeramTec form the heart of various atomisers. As soon as an alternating voltage is applied to them, they begin to oscillate at a high frequency. The oscillating effect of the piezoceramics excites the medication either directly or indirectly and produces small droplets that the patient can inhale.
