Ocular treatment apparatus
First Claim
1. An ocular treatment apparatus for applying medicament into an eye, said apparatus comprising:
- an inner housing member including an eyepiece portion on a free end thereof, said eyepiece portion having a peripheral edge defining an opening, said peripheral edge being shaped for conformable engagement with the facial tissue surrounding an eye, said inner housing member further including a body portion connected to said eyepiece portion for receiving a vial of medicament for application to the eye;
an outer housing member defining an open free end, said open end being slideably engaged over the other end of said inner housing member, said outer housing member further defining a medicament displacement member projecting outwardly from the end opposite said free end and into said body portion of said inner housing member, said displacement member being depressible against a flexible vial received within said body portion of said inner housing member by sliding said outer housing member toward said eyepiece portion to displace medicament from the vial and, in turn, through said opening in said eyepiece portion and into the eye; and
means for displacing the lower eyelid of an eye coupled to said outer housing member, so that medicament released from the vial may be applied to the ocular cul-de-sac of the eye.

Abstract
An ocular treatment apparatus for applying medicament into an eye has an inner housing member with an eyepiece on a free end thereof. The eyepiece defines an opening in one end thereof, and the opening has a peripheral edge shaped for engagement with the facial tissue surrounding an eye. A body portion of the inner housing member is coupled to the eyepiece and is dimensioned to receive a vial of medicament for application to the eye. An outer housing member of the apparatus has an open free end, which is slidably engaged over the inner housing member. The outer housing member has a displacement rod that projects inwardly from a closed end thereof in the axial direction of the apparatus. The displacement rod is engageable with a flexible vial supported within the body portion of the inner housing member. The displacement rod flexes the vial inwardly to dispense medicament therefrom into an eye. A flexible bar is mounted to the outer housing member, and the free end of the flexible bar is adapted to be engaged with the facial tissue below an eye to displace the facial tissue, and thus displace the lower eyelid, to direct the medicament into the exposed ocular cul-de-sac of the eye. The flexible member is engaged with the facial tissue by moving the outer housing member toward the eyepiece, which simultaneously displaces the lower eyelid and allows the medicament dispensed from the vial to fall into the exposed ocular cul-de-sac of the eye.

4. An ocular treatment apparatus for applying medicament into an eye, said apparatus comprising:
-
an inner housing member including an eyepiece portion on a free end thereof, said eyepiece portion having a peripheral edge defining an opening therethrough, said peripheral edge being shaped for conformable engagement with the facial tissue surrounding an eye, said inner housing member further including a body portion connected on one end to said eyepiece portion for receiving a container of medicament for application to the eye; an outer housing member having an open free end, said open end being slideably engaged over the other end of said body portion of said inner housing member; means coupled to said outer housing member for dispensing medicament from the container received within said body portion through said eyepiece portion and into the eye; and means coupled to said outer housing member for displacing the lower eyelid of an eye to expose the ocular cul-de-sac, so that medicament released from the container is applied to the exposed ocular cul-de-sac of the eye. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16)

17. An ocular treatment apparatus for applying medicament into an eye, said apparatus comprising:
-
a first housing member, said first housing member including an eyepiece portion on one end thereof, said eyepiece portion defining an opening therethrough, the peripheral edge of said opening being shaped for engagement with the facial tissue surrounding an eye, said first housing member further including a body portion coupled to said eyepiece portion, said body portion being adapted to receive medicament to dispense the medicament into an eye; a second housing member coupled to said first housing member and movable relative thereto; means for dispensing medicament from said body portion of said first housing member through said eyepiece portion, said means for dispensing being coupled to said second housing member; and means for displacing the lower eyelid of an eye to expose the ocular cul-de-sac, and thus facilitate dispensing medicament onto the ocular cul-de-sac of the eye, said means for displacing being coupled to said second housing member. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
