Abstract

An ocular delivery system for dispensing liquid eye treatment solution includes an eyecup to be placed over the eye to be treated, a system for forming a crescent shaped mist of treatment solution, and a system for collecting used solution without contaminating the source of fresh solution. The delivery system further includes an integral lid retractor for retracting the upper eyelid during treatment. The system is safe and easy to use as well as hygienic.

Claims

1. An ocular delivery system for spraying a solution onto an eye which comprises:

an eyecup having an equatorial plane; and

means for dispensing said solution while the head of a person to whom the solution is being applied is in a substantially erect position, said dispensing means comprising a plurality of holes arranged in a crescent shaped configured in an interior surface of said eyecup for introducing said solution into said eye at an angle between about 45°

to about 60°

with respect to a plane passing through the center eye of said eye which is substantially parallel to said equatorial plane.

2. The ocular delivery system of claim 1 wherein said holes are located in the upper half of said eyecup.

3. The ocular delivery system of claim 1 wherein said eyecup is formed from a hard plastic material.

4. The ocular delivery system of claim 1 wherein said eyecup is formed from hard rubber.

5. The ocular delivery system of claim 1 wherein said eyecup has a concavely shaped interior surface.

6. The ocular delivery system of claim 1 wherein said dispensing means further comprises means for mounting a container with said eye solution to said eyecup.

7. The ocular delivery system of claim 6 wherein said mounting means comprises an integrally formed portion for receiving a neck of said container and snapping it into place.

8. The ocular delivery system of claim 6 wherein said mounting means comprises an integrally formed receptacle portion having internal threads for engaging a threaded portion of said container.

9. The ocular delivery system of claim 6 wherein said dispensing means further comprises:

a hollow chamber in said eyecup;

said hollow chamber having an aperture for receiving a tip portion of said container; and

said plurality of holes communicating with said hollow chamber.

10. The ocular delivery system of claim 9 further comprising:

an O-ring positioned within said hollow chamber for properly positioning said container and preventing splash back of said solution.

11. An ocular delivery system for spraying a solution onto an eye which comprises:

an eyecup having an equatorial plane;

means for dispensing said solution while the head of a person to whom the solution is being applied is in a substantially erect position, said dispensing means comprising means for introducing said solution into said eye at an angle between about 45°

to about 60°

with respect to a plane passing through the center of said eye which is substantially parallel to said equatorial plane;

means for collecting used solution, eye debris and eye secretions; and

said collecting means being located within a lower half of said eyecup.

12. The ocular delivery system of claim 11 wherein said collecting means comprises:

a hollow chamber within a lower portion of said eyecup;

a plurality of holes communicating with said chamber for removing said used solution, eye debris and eye secretions from said eyecup; and

an outlet opening communicating with said chamber.

13. The ocular delivery system of claim 12 wherein said collecting means further comprises an upturned edge portion for directing said used solution, eye debris and eye secretions toward said holes and said chamber.

14. An ocular delivery system for spraying a solution onto an eye which comprises:

an eyecup having an equatorial plane;

means for dispensing said solution while the head of a person to whom the solution is being applied is in a substantially erect position, said dispensing means comprising means for introducing said solution into said eye at an angle between about 45°

to about 60°

with respect to a plane passing through the center of said eye which is substantially parallel to said equatorial plane; and

said eyecup having an integrally formed blunt edge which acts as an upper eyelid retractor.

15. An ocular delivery system for applying a liquid to a person'"'"'s eye while the head of said person is in a substantially erect position which comprises:

an eyecup having an upper half and a lower half;

means for applying said liquid to said eye positioned solely in said upper half; and

means for collecting used solution and removing it from said eyecup located in said lower half.
