Abstract

An apparatus for administering a fine mist of an ophthalmic solution to the eyeball of a human. The apparatus is a spray applicator which features the provision of a baffle in the lower portion of an eyecup. The baffle is spaced from the inner surface of the eyecup, with the lateral ends or the entire lower periphery of the baffle being attached to the inner surface of the eyecup. A container such as an aerosol can or plastic squeeze bottle holding the ophthalmic solution is provided, together with ancillary elements to transmit the solution, so that the ophthalmic solution can be projected at will, i.e. when the eyecup is emplaced over an eyeball, into the lower portion of the eyecup opposite the baffle, so that the solution impinges on the baffle rather than directly impinging on the eyeball, the solution thus being effectively dispersed into a mist of small droplets within the eyecup, which mist thus uniformly and gently coats the outer surface of the eyeball. The central portion of the eyecup is preferably composed of a material such as glass, plexiglass or lucite which transmits light, i.e. the central portion of the eyecup is translucent or transparent.

Claims

1. An ophthalmic spray applicator which comprises a generally hemispherical eyecup, a baffle adjacent the annular periphery of said eyecup and within the lower portion of said eyecup, said baffle being generally parallel to and spaced from the inner surface of said eyecup with the lateral ends or entire lower periphery of said baffle being attached to the inner surface of said eyecup, means to project an ophthalmic solution into the lower portion of said eyecup opposite said baffle, so that said solution impinges on said baffle rather than directly impinging on an eyeball, said solution thereby being effectively dispersed into a mist of small droplets within said eyecup, and means in said eyecup to attract vision, said means to attract vision being rearward from both the annular periphery of said eyecup and said means to project an ophthalmic solution.

2. The applicator of claim 1 in which the baffle is curved.

3. The applicator of claim 2 in which the radius of curvature of the baffle approximates the radius of curvature of the eyecup.

4. The applicator of claim 1 in which the baffle is a flat planar member.

5. The applicator of claim 1 in which the means to project an ophthalmic solution into the lower portion of the eyecup is an aerosol spray means, whereby the initial aerosol spray is further comminuted by contact with the baffle.

6. The applicator of claim 1 in which the means to project an ophthalmic solution into the lower portion of the eyecup is a means to intermittently squirt a linear stream of solution against the baffle, so that the linear stream of solution is effectively converted into a dispersed mist of small droplets within the eyecup.

7. The applicator of claim 1 in which the ophthalmic solution is projected radially inwards into the lower portion of the eyecup and against the baffle.

8. The applicator of claim 1 in which the ophthalmic solution is an aqueous isotonic solution.

9. The applicator of claim 1 in which the means in said eyecup to attract vision is the central portion of the eyecup, and in which said central portion of the eyecup transmits light.

10. The applicator of claim 9 in which the central portion of the eyecup is translucent.

11. The applicator of claim 9 in which the central portion of the eyecup is transparent.

12. An ophthalmic spray applicator which comprises a generally hemispherical eyecup, the central portion of said eyecup being provided with means to attract vision, a baffle adjacent the annular periphery of said eyecup and within the lower portion of said eyecup, said baffle being generally parallel to and spaced from the inner surface of said eyecup with the lateral ends or entire lower periphery of said baffle being attached to the inner surface of said eyecup, and means to project an ophthalmic solution into the lower portion of said eyecup opposite said baffle, so that said solution impinges on said baffle rather than directly impinging on an eyeball, said solution thereby being effectively dispersed into a mist of small droplets within said eyecup.

13. The applicator of claim 15 in which the central portion of the eyecup is translucent.

14. The applicator of claim 15 in which the central portion of the eyecup is transparent.

15. The applicator of claim 12 in which the central portion of the eyecup is light transmissible, so that the central portion of the eyecup attracts vision when the eyecup is emplaced in juxtaposition with an open eye, with said open eye being covered by the eyecup.
