Abstract
Embodiments herein describe a portable device for administering a physiologically active liquid that includes a container for holding the liquid, a pressure system for applying pressure to the liquid, an atomizer for atomizing the liquid, and an applicator for administering atomized liquid. The atomizer includes at least one nozzle through which liquid can be ejected from the container and an impact element on the nozzle outlet side that is functionally combined with the nozzle. Moreover, the atomizer is configured in such a way that, in a pressure range that can be generated with the pressurizing system, liquid emerging from the nozzle breaks up into droplets prior to striking the impact element.
Claims25
A portable device for administering a physiologically active liquid, comprising:
- a container for holding the liquid;
- pressurizing means for applying pressure to the liquid;
- an atomizer for atomizing the liquid;
- and
- an applicator for administering atomized liquid,
- wherein the atomizer comprises:
- at least one Rayleigh nozzle through which the liquid is ejected from the container, and
- an impact element, wherein the atomizer is configured such that, in a pressure range generated with the pressurizing means, a liquid jet emerging from the at least one Rayleigh nozzle breaks up, under a free break up regime, into almost monodisperse droplets prior to striking the impact element, the impact element on a nozzle outlet side for impact atomization to atomize the droplets from the liquid jet, the impact element being functionally combined with the at least one Rayleigh nozzle.
