Abstract

The present invention is directed to a thermal covering that delivers consistent therapy to a portion of a user'"'"'s hand-wrist area, is easy to use and apply to the body, and is securely positionable on the body. The thermal covering can be entirely disposable after one use. The thermal covering can also have a disposable component and a reusable component that can be packaged individually together as a kit.

Claims

1. A thermal covering for use on the hand-wrist area of a user comprising:

(a) a chassis having a longitudinal axis and a transverse axis and comprising a flexible body portion having at least one thermal region;

(b) a thermic component irreversibly incorporated into said body portion at said thermal region wherein said thermic component comprises at least one continuous layer of material and a plurality of individual heat cells spaced apart and fixed to the at least one continue layer of material, said thermic component being integral with said chassis; and

(c) a digit-receiving aperture through said body portion and adjacent to said thermal region;

(d) a releasable attachment element to releasably attach the thermal covering around the hand-wrist area of the user.

2. The thermal covering of claim 1 further comprising a flexible retaining element.

3. The thermal covering of claim 2 wherein at least one of said body portion and said flexible retaining element comprises an elastomeric material;

and wherein at least one of said body portion and said flexible retaining element is stretchable along said longitudinal axis of said chassis.

4. The thermal covering of claim 3 wherein said flexible retaining element comprises at least one strap portion fixedly attached to said body portion adjacent to said thermal region, and wherein said strap portion comprises an attachment element.

5. The thermal covering of claim 3 wherein said flexible retaining element comprises two strap portions fixedly attached to said body portion adjacent said thermal region.

6. The thermal covering of claim 2 wherein said digit-receiving aperture is oriented in a transverse axis of said chassis and is located distally from said retaining element.

7. The thermal covering of claim 1 comprising a plurality of digit-receiving apertures.

8. The thermal covering of claim 1 wherein said digit-receiving aperture is selected from the group consisting of a slit, a slot, and combinations thereof.

9. A thermal covering kit comprising:

(a) a chassis having a longitudinal axis and a transverse axis and comprising a flexible body portion having at least one thermal region integral with said chassis, wherein said body portion comprises a digit-receiving aperture through said body portion and adjacent to said thermal region;

(b) a thermic component irreversibly incorporated into said body portion at said thermal region, wherein said thermic component comprises at least one continuous layer of material and a plurality of individual heat cells spaced apart and fixed to the at least one continuous layer of material; and

(c) a releasable attachment element to releasably attach the thermal covering around the hand-wrist area of a user, wherein the thermal covering is packaged in a removable air-impermeable package.

10. The kit of claim 9 further comprising a flexible retaining element, wherein at least one of said body portion and said flexible retaining element comprises an elastomeric material, and wherein at least one of said body portion and said flexible retaining element is stretchable along said longitudinal axis of said reusable chassis.

11. The kit of claim 9 wherein said digit-receiving aperture is oriented in a transverse axis of said chassis and oriented distally from said retaining element.

12. The kit of claim 9 further comprising usage instructions selected from the group consisting of:

written instructions, pictorial instructions, and combinations thereof.

13. The kit of claim 9 further comprising a sleeve having an interior, an open first end and an open second end, wherein said sleeve further comprises a digit-receiving aperture through which a user'"'"'s thumb is insertable, and wherein said sleeve comprises material selected from the group consisting of:

bandage wrap materials, natural rubbers;

reclaimed rubbers;

synthetic rubbers;

styrene block copolymers;

polyurethane;

metallocene-catalized polyethylene;

foams;

knits;

films;

elastomeric scrims, strands, ribbons, tapes;

non-woven materials;

laminates of non-wovens and the preceding materials; and

combinations thereof.
