Abstract

A device and method for applying compressive hot or cold therapy to a patient'"'"'s body, including a handle and a frame connected to and extending from the handle. The frame includes two spaced apart support arms, the support arms each having an opening such that the openings in the support arms are collinear with one another. A roller having a central axis and a reservoir within its interior for retaining a thermal medium, the roller having a non-uniform cross-section along its length defining a thermally conductive external surface for transferring thermal energy from the thermal medium to the patient'"'"'s body. At least one elongated member is operatively connected to the roller and extends longitudinally along the central axis beyond the periphery of the roller. The elongated member is received within the collinear openings of the spaced apart support arms to releasably and rotatably connect the roller to the frame.

Claims

1. A device for applying compressive hot or cold therapy to a patient'"'"'s body, comprising:

a handle;

a frame connected to and extending from the handle, the frame including two spaced apart support arms, the support arms each having an opening such that the openings in the support arms are collinear with one another;

a roller having a central axis and a reservoir within its interior for retaining a thermal medium, the roller having a non-uniform cross-section along its length defining a thermally conductive external surface for transferring thermal energy from the thermal medium to the patient'"'"'s body; and

at least one elongated member operatively connected to the roller and extending longitudinally along the central axis beyond the periphery of the roller, the elongated member being received within the collinear openings of the spaced apart support arms to releasably and rotatably connect the roller to the frame.

2. The device of claim 1, wherein the roller has a generally concave cross-section along its length.

3. The device of claim 1, wherein the roller has a generally convex cross-section along its length.

4. The device of claim 1, wherein the elongated member comprises an axle that extends longitudinally along the central axis through the roller.

5. The device of claim 4, further comprising a threaded coupling that releasably engages corresponding threads on at least one end of the axle to releasably connect the roller to the frame.

6. The device of claim 1, wherein the elongated member includes a pin that extends longitudinally from a lateral edge of the roller along the central axis.

7. The device of claim 6, wherein the elongated member includes a second pin that extends longitudinally from an opposing lateral edge of the roller along the central axis.

8. The device of claim 1, wherein the opening in each support arm is defined and partially surrounded by two flexible opposing jaws that are separated by a gap, the opposing jaws being movable between a normally closed position in which the gap is smaller than the elongated member to retain the elongated member within the opening and an open position in which the gap is larger than the elongated member to permit the elongated member to be inserted into or removed from the opening.

9. The device of claim 1, further comprising a flexible elastic strap having a plurality of openings along its length for receiving an end of the elongated member when the roller is removed from the frame, wherein the roller may be statically maintained in position against the patient'"'"'s body by wrapping the strap about the patient'"'"'s body and inserting each end of the elongated member into a respective opening in the flexible elastic strap.

10. The device of claim 9, wherein each end of the elongated member includes a protrusion extending transversely therefrom to prevent inadvertent removal of the elongated member from the opening in the flexible elastic strap.

11. The device of claim 1, wherein the frame further comprises a neck that connects to the handle at one end and terminates in a pair of lateral members extending laterally from the neck, each lateral member having a terminal end from which the supporting arm extends.

12. The device of claim 1, wherein the handle includes a semi-circular rounded top curvature and a bottom segment having a plurality of indentations that conform to a user'"'"'s fingers when the user grips the handle.

13. The device of claim 1, wherein the roller is adapted to be heated to elevate the temperature of the thermal medium prior to releasably connecting the roller to the frame.

14. The device of claim 1, wherein the roller is adapted to be cooled to lower the temperature of the thermal medium prior to releasably connecting the roller to the frame.

15. The device of claim 1, wherein the thermal medium comprises a refrigerant gel.

16. The device of claim 1, wherein the thermal medium comprises a mixture of water and ammonium nitrate.

17. The device of claim 1, wherein the thermal medium comprises sodium acetate.

18. The device of claim 1, further comprising a vibration motor positioned within the roller.

19. The device of claim 18, further comprising a power source electrically connected to the vibration motor for supplying power to the vibration motor.

20. The device of claim 19, wherein the power source comprises at least one battery positioned within the handle.

21. The device of claim 1, further comprising a heating element positioned within the roller.

22. The device of claim 21, further comprising a power source electrically connected to the heating element for supplying power to the heating element.

23. The device of claim 22, wherein the power source comprises at least one battery positioned within the handle.

24. A method for applying hot or cold message therapy to a patient'"'"'s body, comprising:

providing a thermal medium within a reservoir within a roller having a non-uniform cross-section along its length that defines a thermally conductive external surface for transferring thermal energy from the thermal medium to the patient'"'"'s body;

heating or cooling the roller to raise or lower the temperature of the thermal medium;

releasably and rotatably connecting the roller to two spaced apart support arms of a frame by inserting each end of an elongated member operatively connected and extending along a central axis from the roller through a corresponding opening in the support arms; and

rolling the roller over the patient'"'"'s body by grasping a handle attached to the frame to transfer thermal energy from the thermal medium through the non-uniform, thermally conductive external surface of the roller to the patient'"'"'s body.

25. The method of claim 24, further comprising:

removing the roller from the frame;

positioning the roller against the patient'"'"'s body;

wrapping a flexible elastic strap around the patient'"'"'s body; and

inserting each end of the elongated member into a corresponding opening in the flexible elastic strap to hold the roller in a static position against the patient'"'"'s body.

26. The method of claim 24, further comprising threading a fastener into at least one end of the elongated member to releasably retain the elongated body within the corresponding opening in the support arm.

27. The method of claim 24, further comprising:

positioning each end of the elongated member between two flexible opposing jaws formed on each support arm, the flexible opposing jaws being separated by a gap and partially surround the opening on each support arm;

applying pressure on each end of the elongated member to cause the opposing jaws move from a normally closed position in which the gap is smaller than the elongated member to an open position in which the gap is larger than the elongated member to permit the elongated member to be inserted into the opening.

28. The method of claim 24, further comprising energizing a vibration motor positioned within the roller to cause the roller to vibrate.

29. The method of claim 24, further comprising energizing a heating element positioned within the roller to heat the thermal medium.
