A reservoir assembly for use in an ophthalmic fluid delivery device adapted to deliver an ophthalmic fluid in the form of a mist to an ocular region of a patient is provided, wherein the device has a lumen-defining component configured to deliver the fluid from the reservoir assembly. The reservoir assembly includes a reservoir defining an aperture and a cavity in fluid flow communication with the aperture, a fluid contained in the cavity of the reservoir, and a gasket traversing the aperture. The gasket defines a passage configured to receive a portion of the lumen-defining component and to permit the flow of the fluid from the cavity and through the aperture when the portion of the lumen-defining component is inserted through the passage. The gasket is also configured to substantially prevent the flow of the fluid from the cavity and through the aperture when the portion of the lumen-defining component is not inserted through the passage.

1. An ophthalmic fluid delivery device adapted to deliver an ophthalmic fluid in the form of a mist to an ocular region of a patient, the ophthalmic fluid delivery device having a body; the body including a nozzle assembly, an ultrasonic transducer assembly; and a reservoir assembly; the nozzle assembly dispensing the ophthalmic fluid from the transducer assembly; the body defining a cavity sized to accommodate the reservoir assembly, said body having a body surface contour positioned adjacent said cavity, said reservoir assembly comprising: a reservoir having a wall at least partially defining a cavity;an ophthalmic fluid contained in said cavity of said reservoir; said wall of said reservoir having a reservoir surface contour keyed to the body surface contour to permit insertion of said reservoir assembly into the cavity of the body of the ophthalmic fluid delivery device in a predetermined alignment and to prevent insertion of said reservoir assembly into the cavity of the body in an alignment other than said predetermined alignment; anda lumen that contacts said ophthalmic fluid, the lumen being dimensioned and configured to transport ophthalmic fluid from the reservoir assembly through the transducer by capillary action and has a structure to assure a capillary rise of said ophthalmic fluid sufficient for said ophthalmic fluid to exit said reservoir assembly, wherein the mist of ophthalmic fluid is expelled from the nozzle assembly directly to the ocular region so that the momentum of the mist when received at the ocular region has a magnitude that is insufficient to trigger a blinking or lacrimation reflex of an eye of the patient associated with the ocular region. 2. The ophthalmic fluid delivery device according to claim 1, said reservoir defining an aperture in fluid flow communication with said cavity, said cavity of said reservoir being oriented along a cavity axis and said aperture being oriented along an aperture axis substantially parallel to said cavity axis, said aperture axis being offset from said cavity axis, thereby positioning said aperture proximate said wall of said reservoir and facilitating flow of said ophthalmic fluid from said cavity when said aperture axis is substantially horizontal. 3. The ophthalmic fluid delivery device according to claim 2, said reservoir surface contour being oriented to permit insertion of said reservoir assembly into the cavity of the body of the ophthalmic fluid delivery device in a predetermined alignment substantially parallel to said cavity axis. 4. The ophthalmic fluid delivery device according to claim 1, said wall of said reservoir being substantially cylindrical, said reservoir surface contour extending along a length of said wall substantially parallel to said aperture axis. 5. The ophthalmic fluid delivery device according to claim 1, further comprising a vent opening in fluid communication with said reservoir. 6. The ophthalmic fluid delivery device according to claim 5, further comprising a filter configured to allow air to enter said cavity through said vent opening and to substantially prevent said ophthalmic fluid from escaping from said cavity through said vent opening. 7. The ophthalmic fluid delivery device according to claim 1, wherein the body comprises a spacer assembly being dimensioned and configured to space the nozzle assembly a predetermined distance from the ocular region of a patient. 8. The ophthalmic fluid delivery device according to claim 1, wherein the lumen has an aspect ratio from about 22 to about 26. 9. The ophthalmic fluid delivery device according to claim 1, wherein the body comprises a substantially translucent window and the wall of the reservoir comprises a label with information regarding the ophthalmic fluid and the window allows a user to view the label when the reservoir is within the body. 10. The ophthalmic fluid delivery device according to claim 1, wherein the ophthalmic fluid is selected from the group consisting of diagnostic agents, antibiotics, corticosteroids, antibiotic/corticosteroid combinations, lubricants, tear substitutes, tear production enhancement agents, decongestants, antihistamines, decongestant/antihistamine combination agents, antibacterial agents, antiviral agents, antimicrobial agents, steroidal anti-inflammatory agents, antibiotic/steroidal anti-inflammatory combination agents, nonsteroidal anti-inflammatory agents, topical anesthetic agents, topical anesthetic/fluorescein combination agents, hypertonic saline solution, mydriatic/cycloplegics and miotics. 11. The ophthalmic fluid delivery device according to claim 1, wherein the ophthalmic fluid is an anti-glaucoma agent selected from the group consisting of miotics, alpha-adrenergic agents, carbonic anhydrase inhibitors, beta-blocking agents, prostaglandin analogs, and combination agents. 12. The ophthalmic fluid delivery device according to claim 1, wherein the reservoir surface contour is unique to the ophthalmic fluid. 13. The ophthalmic fluid delivery device according to claim 1, wherein the ophthalmic fluid delivery device discharges the ophthalmic fluid having a velocity of less than 2.5 meters per second. 14. The ophthalmic fluid delivery device according to claim 1, wherein the mist of ophthalmic fluid is expelled from the nozzle assembly at a rate from about 1 to about 3 microliters per second. 15. The ophthalmic fluid delivery device according to claim 1, wherein particles of the mist of ophthalmic fluid expelled from the nozzle assembly have particle sizes of less than 15 microns. 16. The ophthalmic fluid delivery device according to claim 1, wherein the mist of ophthalmic fluid is expelled from the nozzle assembly at a rate from about 1 to about 3 microliters per second and particles of the mist of ophthalmic fluid expelled from the nozzle assembly have particle sizes of less than 15 microns. 17. The ophthalmic fluid delivery device according to claim 1, wherein the mist of ophthalmic fluid expelled from the nozzle assembly has a volume not exceeding 30 microliters when applied to a corneal surface of the eye.
