1. A fluid delivery device, the device comprising:
a drug package having:
(a) a reservoir configured to contain a fluid;
(b) a cavity to accommodate a volume of the fluid from the reservoir;
(c) an aperture through which the fluid in the cavity can be ejected; and
(d) a pathway between the reservoir and the cavity to direct the fluid from the reservoir into the cavity, the pathway having a cross-sectional area smaller than that of the cavity; and
an actuator designed to oscillate against the cavity in order to generate fluid pressure within the cavity and from which the fluid is ejected through the aperture.
