Abstract

A thermal therapy device including a hollow roller having a non-uniform cross-section along its length and a thermally conductive external surface. Two end caps, one on each end of the hollow roller, which, in combination with the thermally conductive external surface of the hollow roller, collectively define a thermal-medium-receiving reservoir and a central axis about which the hollow roller may rotate. A pair of pins, one on each of the end caps, are longitudinally aligned along the central axis.

Claims

1. A thermal therapy device comprising:

a support frame including

two lateral supports, and

two spaced apart support arms,

at least a first of the support arms having on a distal end thereof a pair of prongs, each having a length, the pair of prongs being spaced apart so as to define an opening therebetween and dimensioned to removably receive a pin inserted along a prong-length direction with the spacing being at least a pin-width wide;

a hollow roller having a non-uniform cross-section along its length and a thermally conductive external surface;

two end caps, one on each end of the hollow roller, which, in combination with the thermally conductive external surface of the hollow roller, collectively define a thermal-medium-receiving reservoir and a central axis about which the hollow roller may rotate;

a first pin coupled to one of the end caps and a second pin, coaxially aligned with the first pin, coupled to the other end cap, at least one of the first pin or the second pin being configured to be removably received within the opening between the prongs along the prong-length direction such that

i) the axis and prong length direction collectively define a plane when the first pin is within the opening between the prongs and the second pin is within an opening of a second of the support arms,

ii) when the first and second pins are within their respective openings, a thermal medium is within the reservoir, and the external surface is supported on a therapeutic target at a point on the plane, the hollow roller can rotate freely within the support frame when the support frame is moved perpendicular to the plane, and

iii) when the support frame is moved, along the plane, away from the first pin, the first pin will change from a position within the opening to a position beyond the distal end of the prongs.

2. The thermal therapy device of claim 1, wherein the non-uniform cross-section is generally concave along its length.

3. The thermal therapy device of claim 1, wherein a thermal medium is within the reservoir and wherein the thermal medium comprises:

a refrigerant gel, a mixture of water and ammonium nitrate, or sodium acetate.

4. The thermal therapy device of claim 1, further comprising an electrical mechanism within the hollow roller.

5. The thermal therapy device of claim 4, wherein the electrical mechanism includes at least one of:

a heating element or a vibrating element.

6. The thermal therapy device of claim 4, wherein the prongs are rigid such that, when the support frame is moved, along the plane, away from the first pin, the first pin will change from the position within the opening to the position beyond the distal end of the prongs without requiring flexure of the prongs.

7. The thermal therapy device of claim 1, wherein at least one of the end caps is removable.

8. The thermal therapy device of claim 7, wherein both of the end caps are removable.

9. The thermal therapy device of claim 7, wherein an outer periphery of the at least one removable end cap is dimensioned relative to a peripheral end portion of the hollow roller such that, when the at least one removable end cap is positioned on the hollow roller, a juncture is formed which will not allow a thermal medium in the reservoir to pass from the reservoir through the juncture.

10. The thermal therapy device of claim 7, wherein the at least one end cap is affix-able to the peripheral end via a compression connection.

11. The thermal therapy device of claim 7, wherein the at least one end cap is affix-able to the peripheral end via a threaded connection.

12. The thermal therapy device of claim 1, further comprising a handle coupled to the support frame.

13. The thermal therapy device of claim 1, wherein the hollow roller has an aspect ratio of length to height of at least about 1.5 to 1.

14. A thermal therapy device comprising:

a hollow roller having a non-uniform cross-section along its length and a thermally conductive external surface;

two end caps, one on each end of the hollow roller, which, in combination with the thermally conductive external surface of the hollow roller, collectively define a thermal-medium-receiving reservoir and a central axis about which the hollow roller may rotate,

wherein one of the two end caps has a first configuration in which, a thermal medium, comprising one of a refrigerant gel, sodium acetate, or a mixture of water and ammonium nitrate, can be transferred to or from the reservoir, and, a second configuration, in which a connection with the hollow roller is formed through which the thermal medium cannot pass; and

a pair of pins, one on each of the end caps, when the at least one end cap is in the second configuration, the pins are longitudinally aligned along the central axis.

15. The thermal therapy device of claim 14, further comprising a frame support comprising a pair of lateral supports and two support arms extending therefrom, the two support arms each having pin-receiving openings on a distal end thereof.

16. The thermal therapy device of claim 15, wherein the pins are rotatably located within the pin-receiving openings.

17. The thermal therapy device of claim 14, further comprising a flexible strap having a first hole therein coupled to one of the pins and a second hole coupled to the other of the pins.

18. The thermal therapy device of claim 14, wherein, in the second configuration, the at least one end cap is coupled to the hollow roller by a screw connection.

19. The thermal therapy device of claim 14, wherein, in the second configuration, the at least one end cap is coupled to the hollow roller by a pressure-fit connection.

20. The thermal therapy device of claim 14, wherein at least one of the pins is connectable to its respective end cap by one of:

a screw thread, an O-ring seal or a pressure-fit connection.
