Abstract
Abstract A contact lens holder including a tubular portion constructed for reversably mounting within said holder and which has one end thereof formed for complemental mating with a convex surface of a contact lens and the other end thereof formed for complemental mating with a concave surface of a contact lens. The contact lens holder includes a member having a relatively rigid portion formed adjacent the end of the holder upon which is to be mounted a contact lens to facilitate manipulating and positioning of said end of said holder.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
253 words
A contact lens holder comprising: a first member having an inner fluid chamber and a fluid passage interconnecting said fluid chamber with the exterior of said first member, said fluid chamber being surrounded by wall portions at least a part of which is formed from a deformable material; a hollow, tubular member, said tubular member having one end interconnected to said fluid passage to effect a pressuretight fluid connection between the frEe end thereof and said fluid chamber, said tubular member being constructed for interconnecting either end thereof with said passageway to effect a pressuretight fluid connection between the free end of said interconnected tubular member and said fluid chamber of said first member, said tubular member having an annular, concave surface portion formed about one end thereof for being disposed in one portion of said tubular member relative to said first member, in contacting engagement with a convex surface portion of a contact lens, and an annular, convex surface portion formed about the other end thereof for being disposed, in a second position of said tubular member relative to said first member, in contacting engagement with a concave portion of a contact lens; and said holder including a relatively rigid portion disposed intermediate said deformable wall part of said first member and the free end of said interconnected tubular member whereby the free end of said interconnected tubular member may be firmly maintained in any one of several positions without affecting the pressure existing within said fluid chamber of said first member.
Claim 2
Dependent Claim
253 words
A contact lens holder comprising: a first member having an inner fluid chamber and a fluid passage interconnecting said fluid chamber with the exterior of said first member, said fluid chamber being surrounded by wall portions at least a part of which is formed from a deformable material; a hollow, tubular member, said tubular member having one end interconnected to said fluid passage to effect a pressuretight fluid connection between the frEe end thereof and said fluid chamber, said tubular member being constructed for interconnecting either end thereof with said passageway to effect a pressuretight fluid connection between the free end of said interconnected tubular member and said fluid chamber of said first member, said tubular member having an annular, concave surface portion formed about one end thereof for being disposed in one portion of said tubular member relative to said first member, in contacting engagement with a convex surface portion of a contact lens, and an annular, convex surface portion formed about the other end thereof for being disposed, in a second position of said tubular member relative to said first member, in contacting engagement with a concave portion of a contact lens; and said holder including a relatively rigid portion disposed intermediate said deformable wall part of said first member and the free end of said interconnected tubular member whereby the free end of said interconnected tubular member may be firmly maintained in any one of several positions without affecting the pressure existing within said fluid chamber of said first member.
Claim 3
Dependent Claim
69 words
A contact lens holder as described in claim 1 in which said tubular member has a surface portion disposed in sealing engagement with a surface portion surrounding said fluid passageway, one of said surface portions having boss portions formed thereon while the other of said surface portions has recessed portions formed thereon, at least one of said boss portions being disposed within at least one of said recessed portions.
Claim 4
Dependent Claim
41 words
A contact lens holder as described in claim 1 in which the thickness of the wall of said hollow, tubular member formed adjacent said annular, concave surface area is equal to about one-fourth or more the diameter of said tubular member.
Claim 5
Dependent Claim
30 words
A contact lens holder as described in claim 1 in which the surface portions of the ends of said hollow, tubular member are formed from a relatively soft, yieldable material.
Claim 6
Dependent Claim
253 words
A contact lens holder comprising a first member having an inner fluid chamber and a fluid passage interconnecting said fluid chamber with the exterior of said first member, said fluid chamber being surrounded by wall portions at least a part of which is formed from a deformable material; and a hollow, tubular member, said tubular member having one end interconnected to said fluid passage to effect a pressuretight fluid connection between the free end thereof and said fluid chamber, said tubular member being constructed for interconnecting either end thereof with said passageway to effect a pressuretight fluid connection between the free end of said interconnected tubular member and said fluid chamber of said first member, said tubular member having an annular, concave surface portion formed upon one end thereof for being disposed in one position of said tubular member relative to said first member, in contacting engagement with a convex surface portion of a contact lens, and the other end thereof having a convex surface formed thereon, for being disposed in a second position of said tubular member relative to said first member, in sealing disposition with respect to a concave portion of a contact lens; said holder including a relatively rigid portion disposed intermediate said deformable wall portion of said first member and the end of said interconnected tubular member whereby the free end of said interconnected tubular member may be firmly maintained at any one of several positions without effecting the pressure existing within said fluid chamber of said first member.
Claim 7
Dependent Claim
253 words
A contact lens holder comprising a first member having an inner fluid chamber and a fluid passage interconnecting said fluid chamber with the exterior of said first member, said fluid chamber being surrounded by wall portions at least a part of which is formed from a deformable material; and a hollow, tubular member, said tubular member having one end interconnected to said fluid passage to effect a pressuretight fluid connection between the free end thereof and said fluid chamber, said tubular member being constructed for interconnecting either end thereof with said passageway to effect a pressuretight fluid connection between the free end of said interconnected tubular member and said fluid chamber of said first member, said tubular member having an annular, concave surface portion formed upon one end thereof for being disposed in one position of said tubular member relative to said first member, in contacting engagement with a convex surface portion of a contact lens, and the other end thereof having a convex surface formed thereon, for being disposed in a second position of said tubular member relative to said first member, in sealing disposition with respect to a concave portion of a contact lens; said holder including a relatively rigid portion disposed intermediate said deformable wall portion of said first member and the end of said interconnected tubular member whereby the free end of said interconnected tubular member may be firmly maintained at any one of several positions without effecting the pressure existing within said fluid chamber of said first member.
Claim 8
Dependent Claim
40 words
A contact lens holder as described in claim 5 in which the thickness of the wall of said hollow, tubular member formed adjacent said annular, concave surface is equal to about one-fourth or more the diameter of said tubular member.
