Abstract
Abstract A permanent magnetic arrangement for therapeutic purposes, which comprises one or several rubber-type flexible magnetic foils or strips in which highly coercive permanent magnet particles are embedded in a tube-shape during the therapeutic treatment. The magnetic foils or strips are magnetized perpendicularly to their surface, whereby their magnetic field lines pass through the body section enclosed by the magnetic foil or foil pieces, in cross-wise and/or longitudinal direction. The magnetic foil or foil pieces are positioned in a textile fabric strip, which is provided on its open ends with a fastening mechanism, preferably a Velcro fastener in the form of a bandage. In order to increase the magnetic field line density, the magnetic foils or foil pieces or strips are positioned in layers one over the other, whereby in each case north poles of one foil are opposite south poles of the adjacent foil.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
192 words
A permanent magnetic arrangement for application to a generally tubular member portion of a human body to direct a magnetic flux field thereinto, said magnetic arrangement comprising two rubber-like flexible magnetic foil strips having high coercive permanent magnetic particles embedded in fine distribution in a thermoplastic binder layer, said strips being of identical tubular form for closely surrounding said portion of said body and positioned axially adjacent to but separate from and in axially spaced relationship to one another, each of said tubular strips having a radially inner surface and a corresponding radially outer surface, said inner surfaces of said two axially spaced tubular magnetic foil strips being formed one as a north magnetic pole and the other as a south magnetic pole and the outer surfaces of said two tubular strips being formed as a magnetic pole of opposite polarity to the corresponding inner surface, all of said poles being of equal strength and oriented only perpendicularly to the longitudinal axis of said tubular forms to thereby create a magnetic field therebetween extending longitudinally of the axis of said tubular forms and spanning the axial spacing between the two tubular strips.
Claim 2
Dependent Claim
192 words
A permanent magnetic arrangement for application to a generally tubular member portion of a human body to direct a magnetic flux field thereinto, said magnetic arrangement comprising two rubber-like flexible magnetic foil strips having high coercive permanent magnetic particles embedded in fine distribution in a thermoplastic binder layer, said strips being of identical tubular form for closely surrounding said portion of said body and positioned axially adjacent to but separate from and in axially spaced relationship to one another, each of said tubular strips having a radially inner surface and a corresponding radially outer surface, said inner surfaces of said two axially spaced tubular magnetic foil strips being formed one as a north magnetic pole and the other as a south magnetic pole and the outer surfaces of said two tubular strips being formed as a magnetic pole of opposite polarity to the corresponding inner surface, all of said poles being of equal strength and oriented only perpendicularly to the longitudinal axis of said tubular forms to thereby create a magnetic field therebetween extending longitudinally of the axis of said tubular forms and spanning the axial spacing between the two tubular strips.
Claim 3
Dependent Claim
65 words
A permanent magnetic arrangement according to claim 1, wherein said two axially spaced tubular magnetic foil strips are each constituted by a corresponding plurality of said magnetic foil strips radially layered one on top of another to form a layered assembly thereof, and wherein the surfaces of radially adjacent foil strips which are in contact with each other, are of opposite polarity to each other.
Claim 4
Dependent Claim
51 words
A permanent magnetic arrangement according to claim 2, wherein the axial distance between the axial center points of the north and south poles formed on the said inner surfaces of said two tubular magnetic foil assemblies is at least as great as the inner diameter of the tubular shaped magnetic foils.
