DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
FIG. 1 depicts a preferred form of the finger compress. Within this specification, the invention will generally be referred to as a finger compress. It should be understood that the invention may also be configured for use with toes, and that the use of the term “finger” is not intended to limit the use of the invention to fingers only.
As shown, the compress is substantially tubular in shape, with an internal diameter defined across the span of the internal hollow area. In most examples of the invention, the diameter is smaller than an axial length of the compress, with the axial length extending through middle of the tube and being perpendicular to the diameter. It preferably includes an exterior layer of a flexible material such as a thin sheet of plastic. Any other flexible or elastomeric materials may also be used, and in general the choice of materials is such that it is flexible or semi-flexible at room temperature and is also able to form a leak-proof container for an internal gel or liquid. An internal and an external layer of flexible material is provided, forming an internal volume between the two layers of material.
Although not visible in FIG. 1, the internal volume within the compress is filled with a gel or liquid. Any liquid or gel is suitable within the scope of this invention, and preferably the filler material is able to retain a hot or cold temperature after refrigeration or heating. More preferably, the filler material is able to sustain a cold temperature at which the gel begins to stiffen or freeze into a more solid state so that the compress can serve as a splint as well as a compress. Such gels are currently well known (and further suitable gels may be later developed), and may include mixtures of distilled water, propylene glycol, and thickening agents. Other components such as antibacterial agents may also be included.
The compress 10 includes an external surface 12 and an internal surface 14 defining a volume between the two surfaces. The two surfaces 12, 14 form the internal and external surfaces of a cylinder with a filler material retained within the volume defined by the surfaces. The filler material is preferably a gel or a liquid that is able to retain thermal energy when heated and is also able to substantially maintain a cold temperature when subjected to such a cold temperature for a sufficient period to enable the compress to serve as a cold compress. In alternate forms of the invention, different filler materials are used in hot and cold compress versions in order to provide a first version of a compress that is especially well adapted for use as a cold compress and an second version of a compress that is more particularly adapted for use as a heat compress.
FIG. 2 shows an exemplary use of a preferred compress. As shown a compress 10 (in the form as shown in FIG. 1A) surrounds a first finger 20. Additional compresses may be used on any of the other fingers, and such additional compresses may be the same size, or may be tailored sizes that are configured to accommodate fingers of different sizes. If the gel is properly formulated and refrigerated to reach a solid or nearly solid state, the compresses may each serve as a splint while acting as a compress.
In other examples of the invention, the skin or material of the compress forming the external surface 12 is formed from a semi-rigid or rigid material so that the compress can act as a splint at any temperature, whether hot or cold. In this example, a thicker or more rigid plastic is preferred.
Although FIG. 2 depicts the compress in use with fingers on a human hand, the compress of the present invention can be used equally well with toes on a foot, as illustrated in FIG. 6. In some cases, a single compress will be sized and configured so that it can accommodate either fingers or toes. In other cases, the compress is sized and shaped to be tailored to either a finger or a toe.
FIG. 3 shows a finger with which two compresses are used. In different forms of the invention, a single compress may be configured to be the length of a particular finger, or may be much shorter to accommodate shorter fingers. The shorter versions as shown are preferably sized to be about the length of one of the phalanges on a typical human finger, or about one inch. Thus, two or three compresses may be used in order to encapsulate an entire thumb or finger with this version of the invention. Longer compresses may be the length of a human finger, including versions that are three inches, four inches, or longer in length.
FIG. 4 illustrates a preferred method for producing the compress. Initially a gel-filled sheet 30 is formed, with the sheet being produced in accordance with the description of the preferred compress as described above. In other words, in one example the sheet includes a first layer of a flexible plastic, a second layer of flexible plastic, and an internal filler material comprising a gel. As best seen in FIG. 5, the sheet 30 is rolled in the direction of the arrows to bring the edges 31, 32 adjacent one another. Optionally, the edges may either abut one another or overlap somewhat. The edges are then secured to one another by using an adhesive, heat bonding, or other means. In some forms of the invention, the edges are removably and adjustably secured to one another by using, for example, releasable tape, hook and loop fasteners, or other means.
While FIGS. 4 and 5 depict a method of construction that begins with a flat sheet, the compress may be formed using different processes, including processes that fill a volume between inner and outer layers that are preconfigured into the cylindrical configuration as shown in FIG. 1.
FIG. 1B illustrates another form of the invention. In this example, the compress is formed as a plurality of compress segments. In this case, two segments 16, 17 are shown, although any number of segments may be used. Each of the segments is constructed in accordance with the compress as described above, but the segments are separated from one another by a membrane 18 that seals a volume of gel within each segment individually. Thus, in this fashion one of the segments 16 may be removed from the other segment 17 by trimming along the separation region or membrane 18. In one form, in the separation region the plastic skin of both the inner and outer layers are adhered together. Using scissors or a knife (for example), the segment may be trimmed at the separation region 18 to remove the segment 16.
The inclusion of a separation region enables the compress 10 to be trimmed to a desired length. In one version of the invention, the compress includes several segments that together define the length of a finger. For example, a single multi-segment compress may include 3, 4, 5 or 6 segments. In this form, the user may trim as many or as few segments as desired in order to form a compress of a desired length. In some segmented forms of the invention, the segments are of varying sizes.
In order to use the compress, the compress is trimmed (if necessary, for a segmented version) and either heated or refrigerated to a desired temperature. A finger or toe is inserted into the compress and retained in that position for a desired time in order to receive the therapeutic value of the compress.
While the preferred embodiment of the invention has been illustrated and described, as noted above, many changes can be made without departing from the spirit and scope of the invention. Accordingly, the scope of the invention is not limited by the disclosure of the preferred embodiment. Instead, the invention should be determined entirely by reference to the claims that follow.
