Abstract

A therapeutic stimulatory massage device for receipt therein of a body portion, such device containing a thixotropic fluid medium subject to selective increase in viscosity and increase in pressure at such areas of increased viscosity. Also, other therapeutic modes can be incorporated into the device of this invention.

Claims

1. An apparatus for providing a therapeutic treatment to a body part of an individual comprising:

a fluid containment chamber having a wall formed of a flexible material;

a thixotropic fluid contained in said chamber;

at least one fluid movement device positioned on said fluid containment chamber;

control means for controlling said at least one fluid movement device to produce selectable pressure wave patterns in said thixotropic fluid; and

,

means for selectively actuating portions of said thixotropic fluid to increase its viscosity.

2. An apparatus according to claim 1 wherein said fluid movement device moves said fluid containment chamber wall to create pressure waves in said fluid.

3. An apparatus according to claim 1 including means for directing said pressure wave patterns at a body part.

5. The apparatus of claim 1 wherein said fluid medium is selected from the group consisting of an electrorheologic fluid, a magnetorheologic fluid, and a dilatant.

6. The apparatus of claim 1 wherein said fluid movement devices comprise a plurality of linear actuators.

7. The apparatus of claim 1 wherein said chamber wall further includes:

an upper bladder member and a lower bladder member, said bladder members containing said fluid medium wherein said fluid medium is incapable of flowing out therefrom at any angular position of said apparatus.

8. The apparatus of claim 7 further including means to produce a magnetic field within said containment chamber.

9. The apparatus of claim 1 further including means to produce a magnetic field within said containment chamber.

10. The apparatus of claim 1 further including a covering adapted to be disposed around a body part, said covering preventing direct contact of a body part with said fluid medium.

11. The apparatus of claim 10 wherein said covering includes means to protect said body part from direct contact with electrical current and magnetic fields.

12. The apparatus of claim 11 further including at least one electrode extending through said covering to contact said body part to provide direct electromuscular stimulation thereto.

4. An apparatus for providing a selectable therapeutic treatment to a body part of an individual in need of such treatment and wherein the individual or portion thereof is positioned within a fluid medium contained within a fluid containment chamber having a chamber wall, the improvement comprising:

a plurality of fluid movement devices positioned on said fluid containment chamber, each of said fluid movement devices capable of producing stimulatory activity within the fluid medium contained within said fluid containment chamber sufficient to move said medium for movement of fluid on said individual;

means for selectively controlling the operation of said fluid movement devices in order to produce a desired pressure wave pattern, said pressure wave pattern to create a pressurized zone within said containment chamber, said pressurized zone having a wave pattern being selected from a variety of possible wave patterns to cause a specific therapeutic effect;

said chamber wall being formed of a flexible material;

said fluid medium being of the type in which a thixotropic effect can be created in said pressurized zone placed under pressure by said fluid movement devices; and

means for selectively actuating portions of said fluid medium to create said thixotropic effect to increase said fluid medium'"'"'s viscosity and increase pressure in said pressurized zone against a body part.
