Abstract

DC60 (20/05/42) The dispensing system consists of a sealed container designed to form an internal channel to hold sufficient absorbent material for at least one unit (cose) of ophthalmic solution in the form of a drop. The absorbent material is positioned in the aforementioned channel so that its constricted end protrudes from the opening in the container after the detachable portion of the encapsulation is removed. The constricted portion of the absorbent material forms a drop when the container is held by the opening, facing downwards and opposite to the container, and is squeezed.

Claims (17)

1. An ophthalmic solution dispensing system consisting of (a) a sealed container with an internal chamber, to which the tip can be detached; (b) an absorbent material within the internal chamber, to which the tip can be tapered; and (c) a sterile or preservative ophthalmic solution absorbed by the absorbent material. By detaching the tip from the rest of the container to form an opening in the container, the tapered tip of the absorbent material protrudes from the opening in such a way that when the container with the absorbent material is squeezed by hand and the tapered tip is held pointing downwards, a small drop of ophthalmic solution is formed for instillation into the eye. 2. A dispensing system for ophthalmic solutions under Patent 1, where the absorbent material is selected from a group consisting of urethane, cellulose, and nylon. 3. A distribution system for ocular solution under claim 1, whereby such solution is an ocular solution for the treatment of dry eyes. 4. A dispensing system for ophthalmic solutions under claim 1, whereby such solutions are for the treatment of allergic reactions. 5. A dispensing system for ocular solutions under claim 1, whereby the solution contains selected therapeutic agents from a group of drugs for the treatment of inflammation, infection, cataracts, and intraocular hypertension. 6. Dispensing system for ophthalmic solution under claim 1, whereby the container is a unit dispenser containing 30 to 400 microliters of solution. 7. Dispensing system for ophthalmic solution under claim 7, whereby the container is a unit dispenser containing 50 to 200 microliters of solution. 8. The ocular solution dispensing system of Claim 1, where such sealed container is a sac formed by at least two membranes of impermeable material, such membranes are improperly fused together around the outer edges to form an internal cavity, such a detachable end is removable by tearing along the line connecting the two edges of the sac, and where the absorbent material is positioned in the such an end that it protrudes from the opening formed by tearing along the line connecting the two edges of the sac. 9. The dispensing system for ophthalmic solution of claim 1, whereby the aforementioned sealed container is elongated in shape with a significantly rounded, square or rectangular cross-section, whereby the absorbent material is positioned in the aforementioned internal cavity in such a way that a significantly conical portion protrudes from the opening in the container after the aforementioned end is removed. 10. An ophthalmic solution dispensing system consisting of (a) a sealed bag formed by at least two impermeable membranes, which are sealed together around the outer edges to form an internal cavity; the bag has a detachable end that can be separated by tearing along the connecting line of the two sides of the bag to form an opening in the bag, after which the detachable end is discarded; and (b) an absorbent pad containing the ophthalmic solution, which is positioned in the internal cavity such that one edge protrudes from the opening formed by the removal of the detachable end, with the absorbent pad having a rounded edge for droplet formation when the bag is held with the opening facing downwards and the opposite side of the container is pressed with a finger. 11. Method of administering ophthalmic solution to the eye: (a) Remove one end of the container, exposing the tapered tip of the absorbent material containing the ophthalmic solution; (b) Position the tapered tip above and against the eye; and (c) Press the opposite side of the container with the absorbent material with your finger to release the solution from the absorbent material onto the eye. 12. Method of claim 11, whereby the solution is an ocular solution for the treatment of dry eyes. 13. Method of claim under clause 11, whereby the solution is for the treatment of allergic reactions. 14. The method of claim 11, whereby the solution contains therapeutic agents selected from a group of drugs for the treatment of inflammation, infection, cataracts and hypertension in the eye. 15. Method of claim 11 where the container is a unit dispenser with a defined volume containing 30 to 400 microliters of solution. 16. Method of claim 11 where the container is a unit dispenser with a defined volume containing 50 to 200 microliters of solution. 17. The method of claim 11, whereby the container is a unit-quantity container for the storage of a sterile but preservative-free solution.
