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: 10
Claim 1
Independent Claim
141 words
An eyelid splint adapted to immoblize an eyelid of only one eye of a patient comprises a flexible, resilient pad member adapted to press against the exterior of a patient's eyelid, said pad having a thickness of at least 10 mm, a backing member secured to the pad member, and means for maintaining a pressure of 23-40 mm Hg on the eyelid, said means consisting essentially of 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, 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, the strap means and backing member being fabricated from a single piece of flexible material.
Claim 2
Dependent Claim
141 words
An eyelid splint adapted to immoblize an eyelid of only one eye of a patient comprises a flexible, resilient pad member adapted to press against the exterior of a patient's eyelid, said pad having a thickness of at least 10 mm, a backing member secured to the pad member, and means for maintaining a pressure of 23-40 mm Hg on the eyelid, said means consisting essentially of 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, 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, the strap means and backing member being fabricated from a single piece of flexible material.
Claim 3
Dependent Claim
26 words
The eyelid splint of claim 1 wherein the resilient pad member is a foam pad having a thickness of from about 10 to about 22 mm.
Claim 4
Dependent Claim
23 words
The eyelid 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
17 words

Claim 6
Independent Claim
149 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 immobiolize 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 10 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 integral with and extending outwardly from the backing member for encircling the head of the patient, said strap means and backing member being formed from a single piece of flexible material, 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 7
Independent Claim
149 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 immobiolize 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 10 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 integral with and extending outwardly from the backing member for encircling the head of the patient, said strap means and backing member being formed from a single piece of flexible material, 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 8
Dependent Claim
29 words
