Definitions

  • This invention relates to magnetotherapeutic devices, and more particularly to muscle and/or joint wraps incorporating static magnetic field generators in the form of 5 magnets to provide magnetotherapy to adjacent tissues.
  • Magnetotherapy uses magnetic fields to provide therapeutic and restorative treatment to limbs, organs, and other parts of the body.
  • one means by which magnetotherapy may be achieved is by bringing a magnet or a series of
  • Polar molecules such as water also respond to magnetic fields in a manner similar to that for charged molecules. Additional therapeutic or restorative effects might arise through the alignment of polar molecules as they pass through the magnetic field. When subject to a magnetic field, polar molecules rotate to align themselves with the field. Such alignment would alternate with the magnetic polarity
  • the present invention provides a wrap by which magnetotherapy may be applied to joints and adjacent tissues.
  • a sheet of magnetic material preferably of a highly magnetic material, is both flexible and elastic.
  • this highly magnetic flexible sheet has alternating polarity along its course so that travel in any direction becomes subject to alternating polarity. Strong magnets in the shapes of triangles, squares, and/ or series of concentric circles may be used to provide such alternating polarity.
  • the strong source of magnetism incorporated into the magnetic wrap for joints of the present invention may arise from the use of neodymium-based magnets which may be incorporated into NEOPRENE ® or the like.
  • neodymium-based magnets which may be incorporated into NEOPRENE ® or the like.
  • Magnetic ferrite may also be used in the place of the neodymium-based magnets.
  • an aperture may be cut or fashioned in the sheet of magnetic material so as to accommodate the joint.
  • Such an aperture may accommodate a joint such as a knee, elbow, shoulder, or the like.
  • attachments or attachment elements holding the magnetic sheet in place may be strategically positioned upon the sheet and may take the form such as VELCRO ® hook and fasteners, or the like. Buttons, snaps, and other fasteners may also be used to good advantage.
  • face masks and eye masks may also incorporate such strong magnets so as to provide greater magnetotherapeutic effect for adjacent tissues.
  • face masks have been disclosed in part in prior U.S. Patent Application Serial No. 08/911,950 filed August 15, 1997 which is incorporated herein by this reference thereto.

  • Figs. 11 and 12 show a triangular checkerboard magnet configuration for use in the present invention.
  • Fig. 13 shows a circular and toroidal magnet configuration for use in the present invention.
  • the present invention is directed mainly towards a magnetic wrap for joints by which magnetotherapy may be applied to joints and the adjacent tissue without unduly interfering with the operation of the associated joint. Additionally, strong and alternating static magnets may be used not only in such magnetic wraps for joints, but only eye masks and face masks.
  • FIG. 1 a Figure F is shown wearing several of the different embodiments of the present invention.
  • the magnetic joint wraps ( Figure 2) of the present invention may take several forms in order to accommodate several different types of joints.
  • the Figure F is bearing an ankle wrap 20, a knee wrap 22, a hip wrap 24, a wrist wrap 26, an elbow wrap 28, and a shoulder wrap 30.
  • Neck wraps or the like might be similar to a hip wrap 24 or the like in order to provide a magnetotherapeutic collar or the like.
  • the magnetic joint wraps often incorporate apertures or the like in order to accommodate the joint associated with the adjacent tissue.
  • a hip or wrist wrap configuration is shown indicating such an aperture 40.
  • the aperture 40 is strategically located so that upon wrapping the magnetic joint wrap (generally indicated by reference number 42), the associated joint may protrude through or otherwise be accommodated by the aperture 40.
  • the magnetic joint wrap 42 surrounds and addresses the joint and allows for better articulation of the joint while the magnetic joint wrap 42 is wrapped about it.
  • attachment elements provide means by which the magnetic joint wrap 42 may be attached to the joint.
  • hook and loop fasteners such as that marketed under the name of VELCRO ® may be used to provide detachable attachment means by which the magnetic joint wrap 42 may be attached to the joint and its adjacent tissue or anatomical structures.
  • a first attachment element 50 has a corresponding and oppositely opposed attachment element 52 on a same side of the magnetic joint wrap 42.
  • Both attachment elements 50, 52 take the form of strips or projections that serve to adjustably and attachably engage a second attachment element 54 at the opposite side of the magnetic joint wrap.
  • the exterior of the second attachment element 54 may be a hook portion of the hook and loop fastener while the interior or facing portions of the first attachment elements 50, 52 (portions that would face the second attachment element 54 when serving to attach the magnetic joint wrap 42), may be hook portions of a hook and loop fastener.
  • snaps, buttons, or other means by which non-destructive and detachable fixation may be made between the two ends of the magnetic joint wrap 42 may be achieved may also be used to good advantage.
  • FIGs 3-5 Alternative embodiments of the magnetic joint wrap 42 of the present invention are shown in Figures 3-5 whereby specific joints may be accommodated by specific tailoring of the magnetic joint wrap 42 to the joint and its surrounding tissue.

  • Projecting loop means 70, 74 such as those used in the magnetic joint wrap 42 as shown in Figure 2 can likewise be used in the embodiments shown in Figure 3. While the shoulder fits within the aperture 62, the upper torso is wrapped by a first portion 66 of the magnetic joint wrap 60 while the left arm is wrapped by a second portion 68.
  • Torso attachment means 70, 72 may include VELCRO ® or hook and loop fasteners so that the facing portions of the torso attachment elements 70, 72 when facing each other wrap around the upper left torso of a person.
  • the torso attachment means 70, 72 serve to adjustably and detachably engage one another to affix the magnetic shoulder joint wrap 60 of the present invention to the upper left torso of the person.
  • Similar arm attachment means 74, 76 are used to attach the second arm portion 68 of the magnetic shoulder joint wrap 60 to the upper left arm or bicep of the person. Similar means may be used for the arm attachment elements 74, 76 as for the torso attachment elements 70, 72. In this way, adjustable and attachable means by which the left shoulder magnetic joint wrap 60 of Figure 3 may be attached to the left shoulder of a person may be achieved. Such attachment is shown in Figure 1 and is generally indicated at 30.
  • the embodiment of the present invention accommodating the right shoulder of a person may be achieved by generally creating a mirror image of the left shoulder magnetic joint wrap 60 as shown in Figure 3.

  • strong magnets such as ALNICO or ceramic magnets may be used so long as the flexibly elastic properties of the magnetic wrap are maintained.
  • NdFeB magnets are advantageously used in the present situation as they provide the strongest magnetic fields for magnetotherapeutic purposes.
  • magnetic ferrite can be used to good effect instead of NdFeB magnets.
  • Figures 9-13 show a variety of magnet configurations to provide for alternating magnetic polarity as travel is made along the magnetic sheets forming the magnetic joint wraps 42, etc. of the present invention.
  • changing magnetic fields are encountered by charged molecules or atoms passing sufficiently proximate to the magnetic joint wrap so as to be subject to its magnetic fields. It is known that such changing magnetic fields induce currents and will also serve to exert both repelling and attractive forces upon such charged molecules or atoms.
  • Figures 6-8 eye and face masks are shown which may incorporate strong NdFeB magnets or other flexibly elastic and strongly magnetic components.
  • Figure 6 shows an eye mask 120 having an opaque exterior portion 122 with a nose notch 124.

  • a magnetic indicator 132 indicates a magnetic configuration as incorporated by the eye mask 120 and as reflected by the pattern shown in Figures 11 and 12.
  • the magnetic indicator 132 may have a protective case 134 having a notch 136 by which the indicator 132 is more easily pivoted away from the protective case.
  • the interior portion of the eye mask 120 has the opaque exterior portion 122 providing an opaque interior portion 122 so that light may not pass through the opaque exterior portion 122. This keeps the confines of the eye mask 120 generally dark when it is affixed over a person's eyes.
  • a foam rubber or other comfortable engaging surface 138 circumscribes the perimeter of the opaque portion 122 so as to space apart the opaque portion 122 away from the person's face. This generally keeps the opaque portion from interfering with batting eyelashes or the like which can be a distraction to the person wearing the eye mask 120.
  • the eye mask ends 130 may have wider foam rubber portions that accommodate the sides of a person's face near the eyes.
  • the foam rubber serves as a light-tight gasket that comfortably engages the portions of a person's face surrounding the eyes so as to prevent the transmission of light into the eye mask and onto the person's eyes.
  • a bead or the like 140 may serve to adjustably restrict the length of the elastic band 126 so that it may be adjustably conformed to hold the eye mask 120 to a person's face.
  • the bead 140 may form a secondary loop 142 that serves to eliminate the slack that would otherwise be present in the elastic band 126.
  • a face mask 150 incorporating the superstrong and alternating polarity magnetic structures of the present invention is shown.
  • Magnetic indicators 132 serve to show the checkerboard 152 or series of concentric circles 154 of alternating magnets as is respectively shown in Figures 9 and 10 (for a checkerboard configuration 152) and Figure 13 (for the series of concentric circle configuration 154).
  • the face mask 150 may also use elastic bands 156 with loops for taking up slack 158 created by the adjustable use of adjustment beads 160.
  • the adjustable elastic bands 156 may pass through apertures 162 present at the sides 164 of the face mask 150. Apertures in the face mask 150 may be present to accommodate the eyes 170, the nose 172, and the mouth 174.

The mill gap is gradually opened as the P-4 incorporates into the binder thus increasing the batch volume. The polyethylene wax (AC 617A) can be added with the P-4 at the beginning of the addition process. The same is similarly true for the stearic acid. The rest of the curing mixture is then added at the end of the P-4 addition step.
