Abstract
A method for aerosolising a liquid comprises the steps of: —providing an aperture plate having at least 100 outlet holes per mm2; delivering liquid to the aperture plate; and vibrating the aperture plate to produce an aerosol. The viscosity of the liquid is in the range of from 1 to 15 cP and the surface tension of the liquid is in the range of from 72 to 0.5 mN/m. The output rate of the generated aerosol is greater than 0.01 mL/min.

A method for aerosolising a liquid comprising the steps of:
- delivering liquid to an aperture plate including a reservoir layer having one or more apertures and an outlet layer having at least 100 outlet holes per mm2 wherein the viscosity of the liquid is in a range of from 1 to 15 cP and the surface tension of the liquid is in a range from 72 to 0.5 mN/m;
- and
- vibrating the aperture plate to generate an aerosol wherein an output rate of the generated aerosol is greater than 0.01 mL/min.
A method for aerosolising a liquid comprising the steps of:
- delivering liquid to a domed aperture plate including a reservoir layer having one or more apertures and an outlet layer having at least 100 outlet holes per mm2 downstream of the reservoir layer wherein the viscosity of the liquid is in a range from 1 to 15 cP and the surface tension of the liquid is in a range from 72 to 0.5 mN/m;
- and
- vibrating the domed aperture plate to generate an aerosol wherein an output rate of the generated aerosol is greater than 0.01 mL/min.
A method for aerosolising a liquid comprising the steps of:
- delivering at least one of a medicament, a surfactant, or a pharmaceutical to a domed aperture plate including a reservoir layer having one or more apertures and an outlet layer having at least 100 outlet holes per mm2 wherein the viscosity of the medicament, surfactant, or pharmaceutical is in a range from 1 to 15 cP and the surface tension of the medicament, surfactant, or pharmaceutical is in a range from 72 to 0.5 mN/m;
- and
- vibrating the domed aperture plate to generate an aerosol wherein an output rate of the generated aerosol is greater than 0.01 mL/min.
