Abstract
Abstract An eyelid splint is provided for comfortably immobilizing the lid of an injured or diseased eye. The splint consists of a soft, resilient pad, preferably of synthetic foam having a thickness of at least 7 mm, having a backing which is attached to two elastic straps. The straps have adjustable interengaging fasteners to permit adjustment of the pressure on the eyelid to be between 23 and 40 mm Hg.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
130 words
An eyelid splint adapted to immobilize an eyelid of only one eye of a patient consisting essentially of a flexible, resilient pad member adapted to press against the exterior of a patient's eyelid, said pad having a thickness of at least 14 mm, a backing member for mounting a pad thereon, and means for maintaining a pressure of 23-40 mm Hg on the eyelid, said means consisting essentially of an elastic strap means attached to the backing member for encircling the head of a patient, the strap means comprising first and second elastic strap members each having an end portion, and first and second interengaging fastening members comprising a plurality of mating hooks and loops mounted on the end portions of said straps for fastening said straps at adjustable lengths.
Claim 2
Dependent Claim
130 words
An eyelid splint adapted to immobilize an eyelid of only one eye of a patient consisting essentially of a flexible, resilient pad member adapted to press against the exterior of a patient's eyelid, said pad having a thickness of at least 14 mm, a backing member for mounting a pad thereon, and means for maintaining a pressure of 23-40 mm Hg on the eyelid, said means consisting essentially of an elastic strap means attached to the backing member for encircling the head of a patient, the strap means comprising first and second elastic strap members each having an end portion, and first and second interengaging fastening members comprising a plurality of mating hooks and loops mounted on the end portions of said straps for fastening said straps at adjustable lengths.
Claim 3
Dependent Claim
23 words
The splint of claim 1 wherein the pad is a foam pad having a thickness of from about 14 to about 22 mm.
Claim 4
Dependent Claim
23 words
The splint of claim 1 wherein the pad comprises a highly compressible foam pad having a density of from about 0.7-1.5 lbs/cu. ft.
Claim 5
Dependent Claim
129 words
An eyelid splint adapted to immobilize only one eyelid of a patient consisting essentially of a flexible, resilient foam pad member having a thickness from about 12 to about 22 mm, said foam pad having a compressibility of 5-20 psi i.l.d. and having a density from about 0.7-1.5 lbs/cu.ft., a backing member for mounting the pad thereon, means for maintaining a pressure of 23-40 mm Hg on the eyelid, said means consisting essentially of first and second elastic strap members attached respectively to opposite portions of said backing members at an angle of about 20° to each other, said straps being stretchable by a force of 1.75 newtons to 105%-150% of the unstretched length, and Velcro fastening means mounted on said straps for fastening said straps at adjustable lengths.
Claim 6
Dependent Claim
129 words
An eyelid splint adapted to immobilize only one eyelid of a patient consisting essentially of a flexible, resilient foam pad member having a thickness from about 12 to about 22 mm, said foam pad having a compressibility of 5-20 psi i.l.d. and having a density from about 0.7-1.5 lbs/cu.ft., a backing member for mounting the pad thereon, means for maintaining a pressure of 23-40 mm Hg on the eyelid, said means consisting essentially of first and second elastic strap members attached respectively to opposite portions of said backing members at an angle of about 20° to each other, said straps being stretchable by a force of 1.75 newtons to 105%-150% of the unstretched length, and Velcro fastening means mounted on said straps for fastening said straps at adjustable lengths.
Claim 7
Dependent Claim
13 words
The splint of claim 4 wherein the pad has a substantially uniform thickness.
Claim 8
Dependent Claim
20 words
The splint of claim 4 wherein the compressibility of the foam is from about 8 to about 15 psi i.l.d.
Claim 9
Independent Claim
130 words
A method of immobilizing an eyelid of one eye only of a patient to permit healing of the cornea comprises applying to the eyelid an eyelid splint adapted to immobilize the eyelid, providing the splint with a flexible, resilient pad member adapted to press against the exterior of the patient's eyelid, said pad having a thickness of at least 14 mm and a backing member for mounting the pad thereon, maintaining a pressure on said eyelid of between 23-40 mm Hg, and providing means to maintain said pressure consisting of elastic strap means attached to the backing member for encircling the head of the patient and interengaging fastening means mounted on said elastic strap means to enable securing said strap means to the head of the patient at adjustable lengths.
Claim 10
Independent Claim
130 words
A method of immobilizing an eyelid of one eye only of a patient to permit healing of the cornea comprises applying to the eyelid an eyelid splint adapted to immobilize the eyelid, providing the splint with a flexible, resilient pad member adapted to press against the exterior of the patient's eyelid, said pad having a thickness of at least 14 mm and a backing member for mounting the pad thereon, maintaining a pressure on said eyelid of between 23-40 mm Hg, and providing means to maintain said pressure consisting of elastic strap means attached to the backing member for encircling the head of the patient and interengaging fastening means mounted on said elastic strap means to enable securing said strap means to the head of the patient at adjustable lengths.
Claim 11
Dependent Claim
29 words
The method of claim 7 wherein the pad is a foam pad having a thickness of from about 14 to about 22 mm and a density of 0.7-1.5 lbs/cu.ft.
