A process and a nebulizer for dispensing a consecutively dose of a medicament in the form of a mist, comprising: an energy source (ES), an air-containing volume, an air outlet fluidly connected to the air-containing volume, an air actuator adapted to release a flow of compressed air through the air outlet at such time as a predetermined ES pressure has been reached in the volume and at least two valve means in communication with the air actuator. The compressed air is released at a predetermined pressure of about 20 to about 100 psig. The valve means controls the actuation of the air actuator such that when a medication is nebulized, a mist distribution of a medication is formed having droplets size in the range of approximately 1µ to approximately 7µ which inhaled by a user at a set of predetermined intervals.
B05B 1/02 - Nozzles, spray heads or other outlets, with or without auxiliary devices such as valves, heating means designed to produce a jet, spray, or other discharge of particular shape or nature, e.g. in single drops
B05B 7/28 - Apparatus in which liquids or other fluent materials from different sources are brought together before entering the discharge device in which one liquid or other fluent material is fed or drawn through an orifice into a stream of a carrying fluid
B05B 11/06 - Gas or vapour producing the flow, e.g. from a compressible bulb or air pump
A process and a metered dose inhaler, comprising: an air actuator comprising at least one inlet of liquefied gas (LG), at least one air outlet, at least one first LG-expanding volume and at least one second air-containing volume, the first and second volumes are effectively separated by means of a LG-blocking member; a container with an LG source; said container is in a fluid connection with said LG-expanding volume via the at least one LG inlet; The air actuator is facilitating a metered dose airflow by allowing the expansion of said LG in said at least one LG-expanding volume from its condensed liquid phase to its expanded gas phase. The expansion of said LG facilitates the compression of the air within said at least one air-containing volume, such that a metered dose LG-free air flow is inhalable via at least one air outlet.
