Abstract
Abstract A flexible magnetic sheet for therapeutic use made of a rubbery-flexible synthetic material in which permanent-magnetic ferrite particles have been embedded, the surface facing the body site to be treated of said sheet having been magnetized with magnetic poles of alternating polarities, which poles are in the form of some geometrical shape such as concentrically arranged rings, sectors, quadrangles and the like. Such sheet may also be composed of a plurality of individual parts.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
147 words
A flexible magnetic sheet for therapeutic use by application to a body site comprising: a flexible sheet composed of a skin compatible synthetic material having an active surface with permanent magnetic particles of a ferrite material embedded therein; a first plurality of areas on said active surface having the permanent magnetic particles magnetized to form north poles with respect to said active surface; a second plurality of areas on said active surface closely adjacent said first plurality of areas having the permanent particles magnetized to form south poles with respect to said active surface, the north poles and south poles being arranged in a concentric, angular or radial geometrical pattern thereby establishing magnetic fields having angularities with respect to a line traversing the active surface such that alternating polarities will be traversed by blood flow vessels notwithstanding universal orientation of the body means on the body site.
Claim 2
Dependent Claim
