DROP GENERATING DEVICE
First Claim
1. A device for delivering a fluid to a target, the device comprising:
- a housing;
a reservoir disposed within the housing for receiving a volume of fluid;
an ejector mechanism configured to eject a stream of droplets having an average ejected droplet diameter greater than 15 microns, the stream of droplets having low entrained airflow such that the stream of droplets deposit on a target during use.

Abstract
A method of delivering safe, suitable, and repeatable dosages to a subject for topical, oral, nasal, or pulmonary use and a device for droplet ejection includes a fluid delivery system capable of delivering a defined volume of the fluid in the form of droplets having properties that afford adequate and repeatable high percentage deposition upon application. The method and device include a housing, a reservoir disposed within the housing for receiving a volume of fluid, an ejector mechanism configured to eject a stream of droplets having an average ejected droplet diameter greater than 15 microns, the stream of droplets having low entrained airflow such that the stream of droplets deposit on the eye of the subject during use.

20. A device for delivering a volume of ophthalmic fluid to an eye comprising:
a housing; a reservoir disposed within the housing for receiving a volume of ophthalmic fluid; an ejector plate being in fluid communication with the reservoir, the ejector plate including a plurality of openings formed through its thickness; an actuator formed on a surface of the ejector plate, the actuator being operable to oscillate the ejector plate at a frequency and generate a directed stream of droplets; wherein the droplets in the directed stream have an average ejecting diameter in the range of 20-100 microns and an average ejecting velocity in the range of 2-5 m/s.
-
21. A method for delivering a volume of ophthalmic fluid to an eye of a subject, the method comprising:
-
ejecting a directed stream of droplets of an ophthalmic fluid contained in a reservoir from openings of an ejector plate, the droplets in the directed stream having an average ejecting diameter in the range of 20-100 microns and an average ejecting velocity in the range of 0.5 m/s to 10 m/s, such that the at least 85% of the mass of the ejected stream of droplets deposit on the eye of the subject.
