The present invention relates to cold packs and, more particularly, to a joint compress cold pack.
Cold packs and compression devices have long been used to treat minor injuries of various body parts, such as sprains, swelling, and mild burns. However, current cold packs or other compression devices are difficult to use with small joints, such as finger and toe joints, and/or other joints that are typically hard to reach or difficult to keep cold pack in place due to size and/or movement of the joint. Moreover, traditionally, cold packs do not provide compression specifically to the joint. Additionally, current cold packs are often too large or too small, such that they provide too much compression and/or cold therapy on body parts where it is not needed, or not enough compression and/or cold therapy directly where it is needed, such as a joint. The size of the cold pack, or its inability to stay in place on the desired body part, also frequently limits movement of the patient unnecessarily during therapy.
Many cold packs contain latex, to which some patients are allergic, or contain toxins or other dangerous and/or undesirable chemicals, such as polyvinyl chloride (PVC), bisphenol A (BPA), bisphenol A (BPS), phthalates, formaldehyde, perfluorocarbons (PFCs), 2-(2-Methoxyethoxy)ethanol (DEGME), ethylene glycol monobutyl ether (EGBE), Bis(2-ethylhexyl) phthalates (DEHPs), and dioxins. Finally, many cold packs are intended for only one use and may not be refrozen once used.
The present invention is aimed at one or more of the problems identified above.
In one embodiment, a cold pack is provided. A cold pack comprises a cylindrical outer casing, a liquid comprising an anti-freeze material and water encased within the cylindrical outer casing, and an aperture formed in a middle of the cylindrical outer casing filled with the liquid, wherein the aperture accepts a selected body part of a patient.
In another embodiment, method for using a cold pack is provided. The method comprises a first step of freezing the cold pack for a predetermined period of time, wherein the cold pack comprises: a cylindrical outer casing, a liquid comprising an anti-freeze material and water encased within the cylindrical outer casing, and an aperture formed in a middle of the cylindrical outer casing filled with the liquid. The method comprises a second step of accepting, through the aperture of the cylindrical casing, a selected body part of a patient.

The present invention provides a joint compress cold pack 100. Referring now to
The joint compress cold pack 100 comprises a flexible outer casing 110. The outer casing 110 may comprise a tube/cylindrical casing, the inside of which is filled with a mixture of water and an anti-freeze material 120. The anti-freeze material 120 may comprise a liquid, solid, or semisolid (such as a gel). The anti-freeze material 120 may comprise propylene glycol or other type of anti-freezing agent, that may become cold when placed in a refrigerator or freezer, but will never freeze completely. An aperture 130 is formed in the middle of the outer casing 100.
The outer casing 110 may be comprised of any material of suitable flexibility and durability. By way of example and not limitation, the outer casing 110 may comprise thermoplastic rubber (TPR), thermoplastic elastomers (TPE), including, for example, thermoplastic polyurethane (TPU), thermoplastic olifins (TPE-o), styrenicblock copolymers (TPE-s), thermoplastic copolyesters, thermoplastic copolyamides, thermoplastic vulcanisates (TPE-v or TPV), or elastomertic alloys.
In one embodiment, the joint compress cold pack 100 may optionally comprise a secondary casing (not shown) around the outer casing 110. The secondary casing may comprise a thin material, such as spandex, for additional comfort (e.g., to protect the skin from the cold outer casing 110).
The joint compress cold pack 100 may be of any size to comfortably fit on a joint. Referring now to
According to illustrated embodiment, the joint compress cold pack 100 may be about 1 to 2 inches wide, 2 to 3 inches long, and 1 to 2 inches in depth, such that it fits comfortably on most adult fingers and toes. However, it will be understood that the joint compress cold pack 100 may be different sizes for different applications other than for use on human fingers, such as for other body parts that include joints, including toes, wrists, ankles, knees, and elbows, and/or for body parts that require 360-degree therapy, such as parts of the legs and arms, and/or any other suitable body part. For example, according to an alternate embodiment, the joint compress cold pack 100 may be about 4 inches wide and 4 inches long for use on a wrist. In another embodiment, the joint compress cold pack 100 may be about 6 inches wide and 6 inches long for use on an elbow. In yet another embodiment, the joint compress cold pack 100 may be about 8 inches wide and 8 inches long for use on a knee. In yet another embodiment, the joint compress cold pack 100 may be about 12 inches wide and 8 inches long for use on a shin.
In other embodiments, the joint compress cold pack 100 may be different sizes based on the intended patient. For example, the joint compress cold pack 100 may be smaller to fit on smaller adults or children, or the joint compress cold pack 100 may be larger to fit on larger adults. It is envisioned that the joint compress cold pack 100 could also be used for non-human applications, such as veterinary applications, wherein the size of the joint compress cold pack 100 would be tailored to the specific intended use.
The joint compress cold pack 100 of the present invention provides several advantages over the prior art. First, the joint compress cold pack 100 provides compression to joints that are typically hard to reach or difficult to keep a cold pack in place due to size and/or movement of the joint. Second, whereas traditional cold pack are often too large or too small, such that they provide too much or not enough compression and/or cold therapy, the joint compress cold pack 100 can be tailored to any size based on the target joint. Third, the composition of the joint compress cold pack 100 creates an easy, roll-on application, and the joint compress cold pack 100 stays in place once applied to the joint. Fourth, the joint compress cold pack 100 may be comprised of latex-free and non-toxic materials and fillers, and does not require the use of dangerous and/or undesirable chemicals, such as polyvinyl chloride (PVC), bisphenol A (BPA), bisphenol A (BPS), phthalates, formaldehyde, perfluorocarbons (PFCs), 2-(2-Methoxyethoxy)ethanol (DEGME), ethylene glycol monobutyl ether (EGBE), Bis(2-ethylhexyl) phthalates (DEHPs), and dioxins. Finally, the joint compress cold pack 100 is reusable and, if desired, may be refrozen.
