摘要：
An aperture plate 1 comprises an inlet surface 2 for receiving a liquid to be aerosolised, an outlet surface 3 and a plurality of apertures 4 extending therebetween. The apertures 4 are tapered from an inlet opening 10 at the inlet surface 2 to an outlet or exit opening 12. The aperture plate 1 is convex in the direction of the inlet openings 10 and concave in the direction of the exit openings 12. The aerosol exits on the concave side of the aperture plate. The aperture plate of the invention generates an aerosol plume which converges and is particularly suitable for application to the eye.
