Abstract
At least one layer of windings is so arranged to enclose an open space for treatment of a portion of a patient, for example the thorax, or a limb, shaped so that it encloses an open space which is elliptical or oval. The space enclosed thus is an oval or elliptical cylinder and, in a form suitable for treatment of the hip joint, can be an inclined cylinder. The winding is surrounded by a protective layer, for example a polyester resin which additionally can be shaped to provide for a support surface.
Claims8
Coil structure for electromagnetic therapy comprising at least one layer of electrically conductive windings (12) and terminal means (14) connected to the windings to connect the windings to a source (22) of alternating current, said windings enclosing an open space for treatment of a portion of the body of a patient by generating a low-frequency electromagnetic field upon connection of the windings to said source (22), wherein said windings are shaped to form an elliptical cylinder the end faces of said cylinder being inclined with respect to the central axis of said cylinder, such that the space enclosed thereby is oval, or essentially elliptical in cross section.
