Abstract

Abstract The splint of our invention comprises a substantially cylindrical flexible outer member, an inner liner, advantageously a soft material for comfort, and a plurality of stiffening members interposed between the outer member and the inner liner distributed substantially uniformly about the entire circumference of the terminal member or extremity to provide a uniform pressure around the circumference preventing bending. The stiffening members are not completely rigid, advantageously somewhat flexible steel rods, while the flexible outer member can be a piece of rubber tubing.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 157 words
A splint, for a broken terminal member of an extremity or for an extremity, comprising: (a) a substantially cylindrical elastic outer member free of "O" rings and flaps so that pain is not intensified, said cylindrical elastic outer member open at both ends so that it can expand from the nail bed past the first joint of the finger so that the tip of the finger including the nail is visible and not restrictive throughout the healing process; (b) a substantially cylindrical liner inside said outer member, open at both ends and (c) a plurality of stiffening members positioned inside said outer member and each being independent of each other and formed as an integral unit between said liner and said outer member, said stiffening members being stiff enough to substantially prevent bending of said extremity or said terminal member but together with said outer member are flexible enough to allow for swelling and changes in anatomy.
Claim 2
Dependent Claim 157 words
A splint, for a broken terminal member of an extremity or for an extremity, comprising: (a) a substantially cylindrical elastic outer member free of "O" rings and flaps so that pain is not intensified, said cylindrical elastic outer member open at both ends so that it can expand from the nail bed past the first joint of the finger so that the tip of the finger including the nail is visible and not restrictive throughout the healing process; (b) a substantially cylindrical liner inside said outer member, open at both ends and (c) a plurality of stiffening members positioned inside said outer member and each being independent of each other and formed as an integral unit between said liner and said outer member, said stiffening members being stiff enough to substantially prevent bending of said extremity or said terminal member but together with said outer member are flexible enough to allow for swelling and changes in anatomy.
Claim 3
Dependent Claim 30 words
A splint according to claim 1 wherein said stiffening members are distributed uniformly about the circumference of said extremity or terminal member to provide a uniform pressure about said circumference.
Claim 4
Dependent Claim 32 words
A splint according to claim 1 wherein six of said stiffening members are provided and each of said stiffening members is a somewhat flexible steel rod disposed totally independently of each other.
Claim 5
Dependent Claim 25 words
A splint according to claim 1 wherein said elastic outer member comprises an elastic rubber tubing made from the same rubber used for surgical gloves.
Claim 6
Dependent Claim 25 words
A splint according to claim 1 wherein said substantially cylindrical liner is substantially coextensive with said outer member and is made of a soft material.
Claim 7
Dependent Claim 12 words
A splint according to claim 5 wherein said soft material comprises cotton.
