ABSTRACT:
This invention relates to a roller therapeutic appliance and the method of fabricating it.
This invention is a roller therapeutic appliance in which a pressure roller composed of elastic material is rotatably disposed in a center portion of an operational axis having grips at both ends, and characterized in that an annular magnetic field generating source is embedded along an outer periphery of the pressure roller, which contacts with a human body.
According to the invention, the pressure roller is applied and rotated with pressure on a diseased part of the patient, then, not only pressing force due to the pressure roller but also a magnetic field due to the magnetic field generating source embedded in the pressure roller act on the diseased part, thereby both a massaging effect and a magnetic therapeutic effect can be obtained. Moreover, the annular magnetic field generating source can easily be embedded in a predetermined depth in a predetermined positions and can not be exposed from the surface of the pressure roller.
