BACKGROUND OF THE INVENTION
1. Field Of The Invention
The present invention relates to magnetic devices for therapeutic application to the human body, and more particularly to an electromagnetic quadripolar treatment device with a focusing means to increase the intensity, focus and gradient of the field for placement against or in proximity to the human body. The present invention further relates to methods of use of such magnetic treatment devices for the treatment of various animal diseases, complications and disorders such as such as, but not limited to, a) pain and swelling, b) cardiac dysfunction, c) drug resistant seizures and cerebral edema, d) pain and edema sustained in severe bums, e) potentiation of pharmaceutical agents, f) treatment of strokes and protection from cell death following hypoxic injury, g) control of edema and pain and speeding healing following surgical procedures and speeding healing rates of chronic non-healing wounds, and h) control of pain and sludging of sickled cells in sickle cell disease.
2. General Background
Magnetic fields have been applied to the human body for various therapeutic purposes for many centuries. For example, magnetic medical treatment devices for application against selected portions of the human body are disclosed in U.S. Pat. No. 3,921,620; method and apparatus for suppressing neuron action potential firings U.S. Pat. No. 5,312,321; magnetic plasters for improving circulation are disclosed in U.S. Pat. No. 4,489,711; magnetic fields for stimulation of bone growth are disclosed in U.S. Pat. No. 4,105,017; and magnetic stimulation of nerve cells has been accomplished with devices such as the Cadwell Magneto-Electric Stimulator (MES-10) manufactured by Cadwell Laboratories, Inc. of Kennewick, Wash.
Various disease states, tissue and organ malfunction may be the result of loss of membrane stability and normal permeability. These membranes may be cellular or intracellular, but in any case represent malfunction of excitable tissue. This malfunction of excitable tissue may be due to alteration of ion channel function. These various disease and states of malfunction may also be related to alteration of receptor sites or agonist sites of enzymes and/or other such dynamic systems within living organisms and more particularly the human animal. A great variety of symptoms and malfunctions may occur, such as, but not limited to, the above listed disease and/or disorder states.
Unfortunately, many types of ailments, including chronic pain, poor localized blood flow, cerebral edema and certain seizures and injuries cannot be successfully treated with conventional drug, physical therapy or surgical therapies. Because such ailments are often untreatable with conventional therapies, there is a need for alternative therapies that relieve these previously untreatable or poorly treatable conditions.
Accordingly, it is an object of this invention to provide a device that alters the stability of excitable membranes and other charged structures and systems in order to treat aliments of animals.
Another object of the invention is to provide an electromagnetic device for production of an electromagnetic field for treatment of such disorders, such a devise being electromagnetically powered, and having, inter alia, an alternating polarity, quadripolar array which generates a 3 dimensional, steep field gradient.
It is a further object of this invention to provide a device which contains a flux return ring on the back surface away from the body surface which is designed to return the magnetic flux thereby increasing the strength and gradient without altering the center charge and symmetry of the 3 dimensional steep gradient field.
Another object of the invention is to provide a flux focusing ring surrounding the DC electromagnetic coils on the outer perimeter stationed midway between the top and bottom of the flux core of the pole. Attachment means is provided to hold the focusing ring to the outer perimeter of the coils.
It is a further object of the invention to provide an electromagnetic pole of like polarity on the outer surface of each of the 4 poles of the invention such that the top of the core is oriented to the geometric side of the pole such that the axis of the two magnets form a 90° angle. The focusing magnet comprises an iron pole, an iron housing and a copper wire coil.
It is a further object of the invention to control each focusing magnet by a separate rheostat such that the focusing ring containing magnets can focus and balance the symmetry of the therapeutic field.
Additional object of the current invention is to present an array of embodiments for a variety of therapeutic purposes.
A further object of this invention is to reveal a method of design and manufacture of an iron core which will produce a center charging homogenous, static magnetic flux and decreased heat production from EMF induced adherent heat producing currents (referred to as Eddy Currents in AC EMF circuits). In AC circuits, “Eddy” currents are currents due to induced EMF and account for some of the losses in electrical equipment. If we consider a solid iron rotor of a generator or motor, the solid iron rotor cuts magnetic lines of force as it rotates the same as the wire coil of the rotor. The coil has an EMF induced in it in the direction as dictated by “Fleming's Rule” as the “left-hand rule.” The iron core also has an EMF induced in it in the same direction as the coil. This iron core is a low resistance circuit and the current does no work, but merely heats the iron core. The current flow in the core generates a secondary magnetic flux which is of higher frequency than the 60 cycle current and is more aberrant due to the variable resistance of the non-homogenous iron. The higher frequency magnetic flux is erratic due to the reverberating nature of the “Eddy” Currents in the iron core. The resistance of any given position of the conductor in ohms divided into the electromotive force in volts is equal to the current flow in amperes. In the non-homogenous core with lack of continuity of the base-metal crystal structure. The heating effect of the current is proportional to the square of the current. These currents are commonly called “Eddy” currents, but are also known as Foucault currents.
The dominant thinking today suggests that such negative currents do not exist in DC electromagnetic circuits. In the current invention similar currents are a factor which must be dealt with in the design. The predecessor device of the current invention consists of a magnetic flux generator and a D/C static drive power source. The magnetic flux generator comprises a plurality of electromagnetic bodies having at least four magnetic poles substantially in a single plane, the magnetic poles being oriented to define the four vertices of a quadrilateral shape. The four magnetic poles comprise two positive and two negative poles, the two positive poles defining opposite diagonal vertices and the two negative poles defining opposite diagonal vertices of the quadrilateral shape. Each of the magnetic poles are magnetically attracted to the t
