/Delivery Of Small Droplets To The Respiratory System Via Electronic Breath Actuated Droplet Delivery Device
Abstract
An ejector mechanism of a droplet delivery device includes a piezoelectric actuator coupled to an acoustic horn and an aperture plate including a plurality of openings. The piezoelectric actuator and acoustic horn are operable to oscillate the aperture plate at a frequency to thereby generate an ejected stream of droplets. A sealing mechanism is provided at an interface of the aperture plate and a removable fluid cartridge.
