| Abstract: |
A band or strap adapted to be circumferentially fitted about the arm to alleviate the symptoms of tennis elbow. The band incorporates inwardly protruding means of limited circumferential extent for applying a radially directed pressure against that portion of the extensor muscle coextensive therewith when the arm band is circumferentially tensioned and fastened in place about the arm. In its preferred form, the means of limited circumferential extent consists of a semi-compressible, inflated air bag carried in a pocket in the arm band. The protruding air bag applies a radially directed pressure or compressive counterforce against the extensor muscle which is of greater magnitude that the pressure exerted against the other circumferential portions of the arm engaged directly by the arm band.

First Claim:
Show all 11 claims |
I claim:
1. An arm band for alleviating the symptoms of tennis elbow, comprising:
- an elongate strap member adapted to be circumferentially tensioned about the forearm of a tennis player in at least partial overlying relation to the extensor muscle thereof, and circumferentially limited means on said strap member for applying a uniform radially directed pressure to said extensor muscle,
- wherein said circumferentially limited means comprises a pocket protruding inwardly toward said arm, said pocket being in engagement with said at least portion of said extensor muscle when said trap member is fitted about said forearm as aforesaid,
- a semi-compressible pressure element disposed within said protruding pocket,
- wherein said semi-compressible pressure element is an inflated air bag, and
- wherein said pocket comprises a first layer and a second layer disposed coextensively with respect to each other longitudinally of said strap member between a pair of transverse seams, said first layer comprising a portion of the inner circumferential surface of said band so as to engage said at least portion of said extensor muscle when said strap is fitted about said forewarm as aforesaid, said first layer forming an asymetrical pockets, said pocket and said inflated air bag asymetrically protruding radially inwardly when the strap member is circumferentially tensioned about the forearm of said tennis player such that the pressure being applied by said inflated bag in said asymetrically protruding pocket is substantially greater in magnitude then the radially directed pressure applied to portions of the arm spaced from said extensor muscle and coextensive with said strap member when said member is circumferentially tensioned about said forearm as aforesaid.
