Abstract: 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.

Abstract: A respiratory device comprises artificial respiration means for generating and maintaining an oxygen-containing respiratory gas flow. Coupled thereto is a tube with humidification means having an atomizer for humidifying the respiratory gas flow and a humidification fluid source that provides a humidification fluid. A spray nozzle thereof comprises a microscopic spray opening in an atomizer body which provides a passage between inlet and outlet sides of the atomizer body and is able and configured to receive a humidification fluid under increased pressure on the inlet side and deliver a fine mist on the outlet side. The atomizer debouches directly into the respiratory channel of the tube. Pressure means are provided which impose an increased operating pressure on the humidification fluid upstream of the atomizer that is connectable via a fluid conduit to the humidification fluid source and pressure means to receive the humidification fluid under the increased operating pressure.

Abstract: An aerosol generator for generating an inhalation aerosol from an inhalation liquid, includes an intake duct for guiding air to a mouth of a user, and a nozzle, arranged in the intake duct for injecting the inhalation liquid into the intake duct. The nozzle is arranged for generating a Rayleigh droplet train of the inhalation liquid propagating along a droplet train propagation path. The intake duct includes at least two first orifices having at least partly opposing discharging directions extending towards the droplet train propagation path. The at least two first orifices are configured for providing respective first air streams in at least partly opposing directions so as to interact in the droplet train propagation path.

Abstract: Embodiments relate generally to marine geophysical surveying and, more particularly, embodiments relate to methods for acquiring geophysical data by dynamically manipulating survey spread in response a change in location of a target. A method may comprise actuating an energy source in a body of water, wherein a target for a marine geophysical survey system is located beneath a bottom of the body of water. The method may further comprise detecting energy generated by the energy source. The method may further comprise manipulating a position of a survey spread in response to a change in distribution of the target beneath the bottom of the body of water.
