Bi-axial rotating magnetic therapeutic device

What is this patent about?

’198 is related to the field of therapeutic magnetic devices and, more specifically, to apparatuses that generate time-varying magnetic fields for application to human or animal tissue. Traditional magnetic therapy often relies on static magnets or simple single-axis rotation, which limits the penetration and effectiveness of the magnetic flux. The background context highlights the need for a device that can provide more complete angular coverage by varying the magnetic field in multiple directions simultaneously, rather than sweeping in a single, fixed plane.

The underlying idea behind ’198 is to generate a complex, multi-dimensional magnetic field by forcing a magnet to rotate about two different axes at the same time. Instead of a simple spinning motion, the invention uses a mechanical or magnetic drive system to create a bi-axial sweeping action. By rotating a magnetic body around a primary axis while simultaneously causing it to roll or spin around a secondary, oblique axis, the device produces a time-varying field of both magnetic flux density and angular flux displacement, ensuring that the magnetic lines of force cut through tissue at constantly changing angles.

The claims of ’198 focus on a magnetic therapeutic system comprising a spherical magnetic unit that is rotationally coupled to a free-moving member. The independent claims specify that a motor or similar drive means rotates the free-moving member, while the magnetic unit itself is contemporaneously rotated about at least one additional axis. This dual-motion is achieved through a mechanical coupling, such as a gearing or friction arrangement, or via a rod that links the magnetic unit to the rotating assembly, ensuring that the two rotational movements occur in concert.

In practice, the invention is implemented by housing a permanent magnet within a carrier that is spun by an electric motor. As this carrier rotates, a rolling member attached to the magnet assembly makes contact with a stationary track or surface. This physical contact—or in alternative embodiments, magnetic interaction with stationary magnets—imposes a secondary torque on the magnet. This causes the magnet to tumble or roll even as it is being swung in a circle, resulting in a sophisticated magnetic output that is far more dynamic than a standard rotating disk.

This approach differentiates itself from prior art by moving away from fixed-axis rotation, which only produces a repetitive, single-direction sweep. By utilizing a friction-driven or gear-driven secondary rotation, the ’198 patent ensures that the magnetic flux is never static in its orientation relative to the user's body. The use of a spherical magnetic unit and a right-angle drive system allows for a compact, handheld form factor that delivers a high degree of flux variation without the heat and energy demands of complex electromagnetic pulse generators.
