Abstract
The present invention concerns a device for creating a directed spray of liquid or powder particles which is produced by contacting the liquid of powder with a radiation surface of an ultrasonic transducer such as a piezofilm or ultrasound tip. The ultrasonic waves cause the spray to project outwardly from the radiation surface and directs it into a patient's mouth or onto another target. Directed particle spray delivers sharp dosage and uniformed up to 90% particle size drug delivery.
