Abstract

Abstract A toroid or roughly similarly-shaped ankle support which receives and holds an infant's toes, with the infant lying stomach down, spaced a short distance above the surface of the bed. The support is relatively thick where it receives the ankle and is composed of a resilient, soft material to prevent injury. In one embodiment, the support is circular and in the other embodiment, it is rectangular with a portion at the top defined to receive the ankle and tied to the infant's ankle.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 182 words
An orthopedic device which permits the wearer to retain full range of motion by his ankle when his knee bears against an underlying supporting surface and his feet are pointed naturally downwardly, the device comprising: a body composed of a relatively compressible material and having the configuration of a cylinder which has a greater diameter than its thickness; an opening extending through said thickness of said cylinder, said opening being so dimensioned that the device can be placed over the wearer's foot and worn by him at a location above the foot proximate his ankle in a comfortable manner and cannot be readily dislocated by him when his knee bears against an underlying supporting surface with his leg between the knee and ankle being generally parallel to such supporting surface; the dimension of said body from said opening to said body's periphery being sufficient that said periphery is spaced beyond the wearer's toes when said body is compressed by the wearer's weight thereon between said opening and said periphery proximate the wearer's toes which therefore do not touch the underlying supporting surface.
Claim 2
Dependent Claim 182 words
An orthopedic device which permits the wearer to retain full range of motion by his ankle when his knee bears against an underlying supporting surface and his feet are pointed naturally downwardly, the device comprising: a body composed of a relatively compressible material and having the configuration of a cylinder which has a greater diameter than its thickness; an opening extending through said thickness of said cylinder, said opening being so dimensioned that the device can be placed over the wearer's foot and worn by him at a location above the foot proximate his ankle in a comfortable manner and cannot be readily dislocated by him when his knee bears against an underlying supporting surface with his leg between the knee and ankle being generally parallel to such supporting surface; the dimension of said body from said opening to said body's periphery being sufficient that said periphery is spaced beyond the wearer's toes when said body is compressed by the wearer's weight thereon between said opening and said periphery proximate the wearer's toes which therefore do not touch the underlying supporting surface.
Claim 3
Dependent Claim 17 words
An orthopedic device according to claim 1, wherein said body is composed of a resiliently elastic material.
Claim 4
Dependent Claim 15 words
An orthopedic device according to claim 2, wherein said body is composed of foam rubber.
Claim 5
Dependent Claim 15 words
An orthopedic device according to claim 2, wherein said body is composed of foam plastic.
