Abstract
An ultrasonic droplet delivery device and related methods for delivering precise and repeatable amounts of a substance to a user for respiratory use is disclosed. The ultrasonic droplet delivery device generally comprises a body housing, a mouthpiece having an ejector mechanism, and a fluid cartridge having at least one fluid reservoir. In certain embodiments, the ejector mechanism may comprise at least one ultrasonic actuator and at least one aperture plate with a plurality of openings formed through its thickness for ejecting droplets. The device may further comprise at least one differential pressure sensor configured to activate the ejector mechanism upon sensing a pre-determined pressure change within the device to thereby generate the ejected stream of droplets.
