Abstract
A device for applying a medicament to the eye, consisting of a single or pair of eye goggles, into which is sprayed a fine mist or fog of the medicament. The medicament is contained in a canister attached to an aperture in the goggle or goggles, and the mist is generated either by the configuration of the outlet valve, or by means of a baffle disposed within the goggle volume opposite the outlet valve. The container may be a bag-on-valve type of device, with the aerosol propellant outside of the medicament bag, such that the medicament does not come into contact with the propellant. Alternatively, the container may be a metered-dose inhalator type of container operated by manual pressure. Because of the one-way flow operation, and the separation of propellant and medicament, formulation of the medicament with a potentially harmful preservative is not necessary.

43. A device for applying an ophthalmic liquid to at least one eye of a subject, said device comprising:
-
a flexible bag containing said ophthalmic liquid; an output valve assembly at one extremity of said bag; an outer container enclosing said flexible bag, said outer container containing a propellant gas under positive pressure, such that ophthalmic liquid is ejected from said flexible bag when said valve assembly is activated; at least one eye goggle having at least one opening in its rim, said outer container being disposed relative to said at least one goggle such that said ejected ophthalmic liquid is directed through said at least one opening into said at least one goggle; and a nebulizing element configured to disperse said ophthalmic liquid in the form of a mist within said at least one eye goggle. - View Dependent Claims (44, 45, 46, 47, 48, 49, 50, 51, 52)

53. A device for applying an ophthalmic liquid to the eye of a subject, comprising:
-
a rigid container containing said ophthalmic liquid and a propellant gas; an output valve at a first extremity of said rigid container; a housing in which said rigid container is disposed, such that pressure on a second extremity of said container activates said output valve and ejects ophthalmic liquid from said rigid container; at least one eye goggle having at least one opening in its rim, said housing being disposed relative to said at least one goggle such that said ejected ophthalmic liquid is directed through said at least one opening into said at least one goggle; and a nebulizing element configured to disperse said ophthalmic liquid in the form of a mist within said at least one eye goggle. - View Dependent Claims (54, 55, 56, 57, 58, 59, 60, 72)

61. A method of applying an ophthalmic liquid to at least one eye of a subject, the method comprising:
-
providing a dispensing device comprising; a flexible bag containing said ophthalmic liquid, said bag having an output valve assembly at an extremity; an outer container enclosing said flexible bag, said outer container containing a propellant gas under positive pressure; at least one eye goggle having at least one opening, said outer container being disposed relative to said at least one goggle such that said ejected ophthalmic liquid is directed through said at least one opening into said at least one goggle; and a nebulizing element such that said ophthalmic liquid is dispersed within said at least one eye goggle in the form of a mist; and activating said valve assembly such that ophthalmic liquid is ejected from said flexible bag into said at least one goggle. - View Dependent Claims (62, 63, 64, 65, 66, 67, 68, 69, 70, 71)
