Abstract
Methods and devices for handling a fluid and delivering the fluid to the eye. The device has a vibrating element with a plurality of openings through which a fluid is ejected when the vibrated. An enclosure defines a chamber which holds a single application of the fluid. The enclosure may be biased against the vibrating element with a spring load developed in whole or part by the resilient structure of the enclosure. The chamber may be substantially empty after the single application.
Claims27
A device for delivering a volume of fluid to an eye, comprising:
- a fluid ejector comprising a vibrating element with a plurality of openings, the vibrating element having a fluid side and a delivery side with the plurality of openings extending from the fluid side to the delivery side, the fluid ejector ejecting fluid from the fluid side through the plurality of openings to the delivery side when the vibrating element is vibrated;
- and
- an enclosure comprising a wall and a resilient lip positioned adjacent the fluid side of the vibrating element, the lip extending around the plurality of openings, the enclosure and the vibrating element together forming a chamber;
- and
- a pump comprising a first part and a second part movably coupled to one another to change a size of a variable volume cavity of the pump to draw a discrete dose of liquid from a fluid container into the variable volume cavity and eject the discrete dose of liquid into the chamber during a cycle of the pump,
- wherein the resilient lip is configured to separate from the vibrating element to vent air from the chamber as the discrete dose of liquid is ejected into the chamber.
