Estimating the term…
A tracheal administering device for an active substance comprises an endotracheal tube with a ventilation lumen which extends therein to carry a respiratory airflow. A liquid conduit connects with a proximal part to a liquid system for delivering a liquid with the active substance under an increased operating pressure. A distal part of the liquid conduit is coupled to a spraying device, comprising a ceramic spray plate with at least one spray channel. The spray channel has a cross-section smaller than about five micrometres, and receives the liquid on an inlet side of the liquid conduit and delivers therefrom at least one mist jet to the respiratory gas flow. The mist jet comprises a series of droplets of at least substantially the same size into which the liquid has been scattered as a result of Rayleigh instability, this size being at most twice to three times the stated cross-section of the spray channel.
Tracheal administering device for a liquid, comprising an endotracheal tube with a ventilation lumen which extends axially therein and is able and configured to carry a respiratory gas flow, and comprising a liquid conduit which connects proximally to a liquid system able and configured to supply a liquid under an increased operating pressure and from which the liquid is receivable into the respiratory gas flow distally, wherein the liquid conduit is distally coupled to a spraying device comprising a ceramic spray plate with at least one spray channel, wherein the at least one spray channel has a cross-section smaller than about five micrometres, and wherein the at least one spray channel receives the liquid, at least during operation, from the liquid conduit under increased pressure and delivers therefrom at least one mist jet to the respiratory gas flow.
