Abstract

An occular treatment apparatus for applying liquid medicament from a reservoir is provided. The apparatus includes a tubular housing with a first open end adapted to conform to the shape of the facial area surrounding the eye socket. The housing is constructed and arranged to receive, hold and position a reservoir containing the liquid medicament. A sighting opening is included on the housing to properly orient the eye and distract the user from the drops of liquid medicament to be introduced into the eye. An eyelid displacement mechanism is supported on the first open end of the housing at a position diametrically opposed to the sighting opening. The displacement mechanism is adapted to evert the lower eyelid and expose the cul de sac. This combination of an eye focused at the sighting hole and an everted lower eyelid exposes the cul de sac so that drops of medicament dispensed into the eye will more easily and directly be applied at or near the cul de sac where it is temporarily retained to increase the length of time the medicament will medicate the eyeball. In a further embodiment of the instant invention, the lower eyelid displacement mechanism will simultaneously cause drops of to be emitted from the reservoir as the cul de sac is everted to facilitate application of the drops of liquid medicament.

Claims

1. An occular treatment apparatus for applying liquid medicament from a reservoir comprising:

a tubular housing with a first open end adapted to conform to the shape of the facial area surrounding the eye socket, said housing being constructed and arranged to receive a reservoir of liquid medicament, said housing including sighting means for orienting an eye, and displacement means supported by said housing proximate said first open end at a position diametrically opposed to said sighting means, said displacement means being adapted to evert a lower eyelid so that liquid medicament from the reservoir is easily and safely applied to the occular cul de sac.

2. The occular treatment apparatus, as claimed in claim 1, wherein said displacement means includes an engagement body, rotatably connected to said housing proximate said first open end, said engagement body adapted to engage the lower eyelid and evert the lower eyelid when said engagement body is rotatably displaced.

3. The occular treatment apparatus, as claimed in claim 2, wherein said displacement means further includes rotation drive means, which will cause said engagement body to be rotatably displaced when the rotation drive means is activated.

4. The occular treatment apparatus, as claimed in claim 3, wherein said rotation drive means includes a drive shaft with a first end and a second end, said first end pivotally connected to said housing and said second end pivotally and slideably connected to said engagement body in a manner so that pivoting the member about the pivotable connection at first end will cause the curved body to be rotatably displaced.

5. The occular treatment apparatus, as claimed in claim 3, wherein said rotation drive means is constructed and arranged so that activating said rotation drive means will simultaneously rotatably drive the engagement body while causing liquid medicament to be emitted from a reservoir.

6. The occular treatment apparatus, as claimed in claim 2, and including said housing having an aperture through the portion of the housing where a reservoir is received, wherein the displacement means includes a drive shaft having a first end and a second end and a projection therebetween, said projection sized to pass through the aperture to compress a reservoir when it passes through the aperture, said first end of the drive shaft pivotally connected to the housing and said second end of the drive shaft pivotally and slideably connected to the engagement body in a manner to rotatably displace the engagement body when the drive shaft is pivotted about said first end of the drive shat, said the drive shaft positioned on said housing to allow the projection on the drive shaft to pass through the aperture and the projection is positioned on the drive shaft so that when the drive shaft is pivotted about said first end of the drive shaft to rotatably dsiplace the engagement body, the projection will pass through the aperture to compress a reservoir and cause liquid medicament to be emitted from a reservoir.

7. The occular treatment apparatus, as claimed in claim 1, wherein said sighting means includes the portion of the housing proximate the first open end defining an aperture.

8. The occular treatment apparatus, as claimed in claim 1, wherein said sighting means includes the portion of the housing proximate the first open end defining an aperture shaped and positioned to cause a user to rotate their eye more than about 30°

upwards to peer at light passing through the aperture.

9. The occular treatment apparatus, as claimed in claim 2, wherein said sighting means is positioned to cause a user to rotate their eye more than about 30°

upwards from its normal position to peer at the sighting means.

10. The occular treatment apparatus, as claimed in claim 2, wherein said sighting means is positioned to cause a user to rotate their eye more than about 35°

upwards from its normal position to peer at the sighting means.

11. The occular treatment apparatus, as claimed in claim 2, wherein the surface of the portion of said engagement body which engages the lower eyelid is curved.

12. The occular treatment apparatus for applying liquid medicament from a reservoir comprising:

a tubular housing with a first open end adapted to conform to the shape of the facial area surrounding the eye socket, said housing being constructed and arranged to receive a reservoir of liquid medicament, said housing including sighting means for orienting an eye, and displacement means supported by said housing proximate said first open end at a position diametrically opposed to said sighting means, said displacement means being adapted to engage a lower eyelid and coincidentally displace said lower eyelid down and back to uncover the portion of the eye below the pupil while liquid medicament is safely and easily applied to that portion of the eye.

13. The occular treatment apparatus, as claimed in claim 12, wherein said sighting means is positioned to cause a user to rotate their eye more than about 30°

upwards from its normal position to peer at the sighting means.

14. The occular treatment apparatus, as claimed in claim 12, wherein said sighting means includes said first open portion of the housing defining an aperture.

15. The occular treatment apparatus, as claimed in claim 14, wherein the first open portion defining the aperture is positioned and shaped to cause a user to rotate their eye more than about 30°

upwards from its normal position to peer at light passing through the aperture.

16. The occular treatment apparatus, as claimed in claim 12, wherein said displacement means includes an engagement body, rotatably connected to said housing proximate said first open end, said engagement body adapted to engage the lower eyelid and displace the eyelid down and back when said engagement body is rotatably displaced.

17. The occular treatment apparatus, as claimed in claim 16, wherein said displacement means further includes a rotation drive means which will rotate the engagement body when the rotation drive mean is activated.

18. The occular treatment apparatus, as claimed in claim 16, and including said housing having an aperture through the portion of the housing adjacent where a reservoir is placed wherein the displacement means includes a rotation drive shaft having a first end and a second end and a projection therebetween, said projection sized to pass through the aperture to compress a reservoir, said first end of the drive shaft pivotally connected to the housing and said second end of the drive shaft pivotally and slideably connected to the engagement body in a manner which will rotatably dislace the engagement body when the drive shaft is pivoted about said first end of the drive shaft, the drive shaft positioned on the housing to allow said projection on the drive shaft to pass through the aperture and the projection is positioned on the drive shaft so that when the drive shaft is pivoted about said first end to rotatably displace the engagement body, the projection will pass through the aperture to compress a reservoir and cause liquid medicament to be emitted from a reservoir.

19. The occular treatment apparatus, as claimed in claim 18, wherein said sighting means includes said front open portion of the housing defining an aperture.
