First Claim
Patent Images
1. An apparatus for delivering a pharmaceutical product comprising:
- a driver element to generate acoustic energy;
an acoustic lens to focus the acoustic energy generated by the driver;
a delivery system to maintain the pharmaceutical product in a position to receive the acoustic energy from the acoustic lens and cause ejection of a droplet of pharmaceutical product.

Abstract
An inhaler that uses capillary effects to output droplets of pharmaceutical product is described. The inhaler includes transducers and lenses to generate focused acoustic waves. The frequency and pulse width output of the transducers are set to cause capillary action in a reservoir of pharmaceutical product. The capillary action results in the ejection of small droplets of pharmaceutical product at low frequencies.
