Device for removing and replacing soft contact lenses worn on the human eye

Details

Inventors: Cointment, Delma M.;
Assignee:
Primary Examiner: Marbert; James B.
Assistant Examiner:
Attorney, Agent or Firm: Wong; James A.

Squeezed, the flexible cup of the device forms two convex lips which grip a soft contact lens in place on a human eye, deforms the lens, breaking its fluid suction-bond to the eye, allowing easy and gentle removal of the lens from the eye, without fingers touching the eye. The body of the device has a dished end with an elevated rim, an annular lumen and a depressed central segment, which end safely holds soft contact lenses by the variable suction of a flexible bulb, controllable by sliding the other end of the body into the lumen of the bulb. The lens is released by squeezing the bulb.

DETAILED DESCRIPTION What is claimed is: 1.
A device for handling and inserting soft contact lenses comprising in combination: a.
a tubular body member formed with a lumen or axial hole extending from a first end to a second end thereof; b.
a suction bulb of flexible material with an opening through which said tubular body member extends adjacent said first end of said tubular body member; and c.
a plug disposed within said tubular body member adjacent said second end of said tubular body member; wherein said lumen is formed with an enlarged portion adjacent said second end of said tubular body member; said plug includes a main body portion and a stem portion with said main body portion being slightly smaller in diameter than and extending substantially coaxially within said enlarged portion, thus forming an annular passage therebetween; said stem portion extends axially inwardly beyond said enlarged portion of said lumen and is in snug contact with a smaller diameter, axially inward part of said lumen; and said plug is formed with an axial passage in said stem portion and a diametrically extending passage in said main body portion intersected by said axial passage whereby fluid communication is established between the interior of said suction bulb and said lumen at said section end by way of said lumen at said first end, said axial passage, said diametrically extending passage, and said annular passage.
2.
The device for handling and inserting soft contact lenses as defined in claim 1, wherein said suction bulb includes an axially extending rim providing a sliding fit with said tubular body member and said tubular body member includes a radially outwardly extending rib adjacent said first end to preclude said suction bulb from sliding off said tubular body member.
3.
The device for handling and inserting soft contact lenses as defined in claim 1 or claim 2, wherein said tubular body member is formed with a concave face at said second end having a concavity compatible with that of soft contact lens to be handled thereby and wherein said plug also is formed with a concave face with a concavity matching that of said concave face of said tubular body member
