Description
- The present application is a continuation-in-part application of U.S. patent application Ser. No. 10/193,778, filed on Jul. 12, 2002.
- The present invention relates to therapeutic packs, for example, therapeutic packs, used for cooling or heating an area to be subjected to a therapeutic treatment, such as an injured area of a human body.
- Conventional therapeutic packs may be used to provide a therapeutic treatment to an area of a living body to be subject to a cold or heat treatment. For example, therapeutic packs may be used to treat sports related injuries, by providing a cooling or heating temperature to the injured area.
- It is believed that U.S. Pat. No. 4,044,773, which is expressly incorporated herein by reference, refers to a cold therapeutic package, in which water is sealed within an interior of a thin polyurethane bladder. The water is then frozen, resulting in the formation of a thin layer of ice within the bladder. After being exposed to a deforming force, such as a rolling or striking force, the layer of ice is divided into a plurality of small ice particles. These small ice particles may move at least substantially freely relative to one another when the cold therapeutic package is applied to an area to be subjected to a cold treatment, thereby promoting easier application of the cold package to the area. However, the thick materials of conventional cold pack bags do not conform readily to the complex, reentrant curves of the human body, because the-bags must prevent leakage of water or other cooling medium.
- It is an object of the present invention to improve conventional therapeutic packs by providing a pack design that promotes the cooling or heating effects of the therapeutic pack and better conforms to an area to be subjected to a therapeutic treatment.
- It is another object of the present invention to provide a therapeutic pack, which is better suited to provide a cooling or heating temperature to an area to be subjected to a therapeutic treatment.
- It is another object of the present invention to provide a therapeutic pack, which does not require a substantial initial deforming force for subdividing a cooling medium, such as ice, into a plurality of smaller particles.
- To achieve these objects, an exemplary therapeutic pack according to the present invention includes a container, also referred to herein as a bag, having an interior space and a plurality of therapeutic modules situated in the interior space of the container, in which the therapeutic modules move freely, or at least substantially freely, relative to one another without the need for a substantial initial deforming force.
- In this manner, it is believed that the various exemplary therapeutic packs of the present invention may better treat an injury of a living body, for example, a sports related injury of a human body. It is also believed that the therapeutic packs of the present invention provide an advantageous solution for treating injuries in large scale treatment centers, such as hospitals.
- FIG. 1 is a cut-away view showing a first exemplary therapeutic pack according to the present invention.
- FIG. 2 is a cut-away view showing further detail of the temperature modules shown in FIG. 1.
- FIG. 3 is a diagram showing application of an exemplary therapeutic pack according to the present invention.
- Referring now to FIG. 1, there is seen a cut-away view of a first exemplary
therapeutic pack 100 according to the present invention. As shown in FIG. 1, thetherapeutic pack 100 includes abag 110 having aninterior space 115 and a plurality oftherapeutic modules 120 situated within theinterior space 115 of thebag 110. For example, thebag 110 may include more than 1000 sphericaltherapeutic modules 120. In one specific embodiment, each spherical therapeutic module has a diameter of between about {fraction (11/32)} inches and {fraction (13/32)} inches and each weighing, for example, between about 0.4 grams and 0.6 grams. A volume less than one cubic inch, more preferably less than 0.4 cubic inches is preferred for each module, allowing many modules to conform directly to the body surface. Thebag 110 may weigh, for example, about 454 grams when filled with thetherapeutic modules 120, depending on the size of the bag and number and volume of therapeutic modules within. - The
bag 110 may be made of a strong, durable material and should have a suitable thickness, such that thebag 110 conforms to the area to be subjected to a therapeutic treatment. For example, the material of thebag 110 may have a thickness of less than four thousandths of an inch, for exampe, approximately three and one half thousandths of an inch (i.e., 3½ mil). For example, a highly flexible plastic, a high density plastic film, such as a high density polyethylene, a polyurethane, a fabric such as a nylon taffeta, polyester taffeta, polyester/nylon taffeta and other materials may be used to formbag 110. - It is believed that the use of nylon taffeta in
bag 110 is advantageous, since taffeta is less likely to irritate and/or burn the area to be subjected to a therapeutic treatment. It is also believed that taffeta exhibits good conductive properties for conducting the cooling or heating temperature to the area to be subjected to a therapeutic treatment, without causing an ice burn, for example. - Additionally, the
bag 110 may include an antimicrobial and/or antifungal agent to prevent infection. For example, this may reduce the chance of introducing an infectious organism, if the area to be subjected to a temperature treatment includes an open cut and/or abrasion on a human body part. In one embodiment, an antifungal and antimicrobial agent permeates a polyester taffeta bag. - Furthermore, the
bag 110 may be designed in any shape, such as oval, square, rectangular, etc. For example, thebag 110 may include a substantially rectangular bag dimensioned, for example, about 6½ inches by 9 inches, having a thickness of about 1¼ inches, when filled withtherapeutic modules 120 and laid flat. - The
bag 110 may permanently enclose the therapeutic modules 120 (i.e., thebag 110 may be a permanently sealed unit)- or, as shown in FIG. 1, thebag 110 may include anaccess apparatus 125, such as a zipper, hook-and-loop tape (e.g. Velcro®), buttons, straps, a twist tie, a slide-lock (e.g. Ziplock®) and/or snaps, operable to permit access to theinterior space 115 of thebag 110. In this manner, thetherapeutic modules 120 may be replaced if necessary. - In one specific embodiment, the
bag 110 is a polyester taffeta. In an alternative embodiment, the polyester taffeta is lined with a high density polyethylene thin film or some other water impermeable lining. Unlike stiffer materials, polyester taffeta drapes, as that term is used in the fashion industry, meaning that the material easily conforms to the human form under its weight. - The
interior space 115 of thebag 110 between thetherapeutic modules 120 may remain devoid of any material, or may include, for example, afilling medium 130, as shown in FIG. 1. Thefilling medium 130 may include, for example, a gas, such as air or dessicated air, a gelatinous material, a material resistant to expansion when heated (e.g. above 20° C.), a material resistant to freezing when cooled (e.g. below 0° C.) or a chemical substance that generates heat or cold by a chemical reaction or a phase change, for example, without the need for an external cooling or heating source, such as a freezer or heater. - It should be noted that the
interior space 115 of thebag 110 between thetemperature modules 120 may be completely filled with thefilling medium 130 or, alternatively, may only be partially filled with thefilling medium 130. In this manner, thebag 110 may permit thefilling medium 130 to expand within thebag 110 while freezing or heating, without rupturing thebag 110. Alternatively, each shell 205, as shown in FIG. 2, may enclose less than its full volume of atherapeutic medium 210, allowing for expansion of thetherapeutic medium 210. - FIG. 2 shows a cut-away view having greater detail of one embodiment of the
therapeutic modules 120. Thetherapeutic module 120 may include a shell 205 and atherapeutic medium 210 situated within aninterior space 215 of the shell 205. The shell 205 may be any shape, for example, substantially spherical, oval, cubic, irregular, etc. In an alternative embodiment, the therapeutic module may be a solid therapeutic medium. In this alternative, thetherapeutic medium 210 is a material that has a large heat capacity or undergoes a chemical reaction or solid-solid phase change, for example. - The
therapeutic modules 120 may be dimensioned, for example, to be approximately equal in volume or to be two or more different volumes to more densely fill the bag. In one preferred embodiment, eachmodule 120 has a volume less than 0.4 cubic inches. Thus, thetherapeutic pack 100 conforms to contours of the area to be subjected to a therapeutic treatment, more effectively promoting uniform application of heating or cooling, for example, as well as reducing the likelihood that thetherapeutic pack 100 will slip off the area to be subjected to the therapeutic treatment. Further, since the individualtherapeutic modules 120 may be small relative to thebag 110 and move substantially freely to one another, at least some of thetherapeutic modules 120 may come to rest in an area of thetherapeutic pack 100 adjacent to at least a portion of the area to be subjected to the temperature treatment. In this manner, more of thetherapeutic modules 120 may individually contact the portion of a body needing treatment, thereby promoting a more effective treatment. - It should be noted that, although FIGS.1-3 show the
therapeutic modules 120 having approximately equal sizes, thetherapeutic modules 120 may be of varying sizes and/or shapes, permitting thetherapeutic pack 100 to better conform to the contours of the area to be subjected to the temperature treatment and/or better promote the therapeutic effect of thetherapeutic pack 100. Furthermore, a volume less than 0.4 cubic inches and/or a diameter of spherical modules less than about 0.5 inches is preferred, because this allows direct contact of the modules with the area to be treated. - The module shell205 may be of any material operable to contain the
therapeutic medium 210, for example, a rigid plastic, a flexible plastic, a sponge-like material, a composite material, an elastomeric material, a non-organic material, an organic material, or a synthetic material may be used. A shell of polyethylene or polypropylene is preferred for encapsulating phase change materials. Polypropylene is preferred for phase change materials having a phase transition of greater than 20° C. - The
therapeutic medium 210 may include any material operable to provide a therapeutic treatment to the body such as heat or cold therapy. For example, thetherapeutic medium 210 may include a liquid, a solid, and/or a gelatinous material. For example, thetherapeutic medium 210 may be a phase change material, such as water, which provides therapeutic cooling to an area of the body during melting from its frozen state to its liquid state. Thetherapeutic pack 100 may provide repeated therapeutic treatment by refreezing the liquid water, for example, in a freezer compartment. Water is a convenient phase change material, because it undergoes a phase change at 0° C., a temperature easily achieved in an ordinary freezer compartment. - Also, water has a large heat of fusion, which provides prolonged cooling of the area of the body undergoing treatment, and water is non-toxic. Thus, water is safe and effective. Other phase change materials are known that are also safe and effective. For example, PCM are available having a range of phase transition temperatures from −31° C. to 90° C., such as the materials offered by TEAP Energy and other firms.
- In addition to or in lieu of a liquid, the
temperature medium 210 may include, for example, a chemical cooling or heating agent operable to provide the cooling or heating temperature via a chemical reaction, without the need for being externally cooled or heated. - It should be noted that the
interior space 215 of the shell 205 may be completely filled with thetemperature medium 210 or, alternatively, only be partially filled with thetemperature medium 210. Partially filling the shell 205 with thetemperature medium 210 may permit thetemperature medium 210, for example, liquid water, to expand within the module container 205 while freezing or heating, without rupturing the shell 205. - It should also be noted that, although FIG. 2 shows the shell205 filled with the
temperature medium 210, theinterior space 215 of the module container 205 may alternatively be filled with air or be devoid of anytemperature medium 210 whatsoever. Alternatively, thetemperature 210 may be a solid that has the same composition as the shell, such as a material with a high heat capacity, creating a solidtherapeutic module 120. - Referring now to FIG. 3, there is seen a diagram showing the application of an exemplary
therapeutic pack 100 according to the present invention. When applied to an area to be subjected to a cold orheat treatment 305, for example, an injured portion of the human body (e.g., a human knee), thetherapeutic modules 120 of thetherapeutic pack 100 move substantially freely relative to one another, even if thetherapeutic pack 100 is applied immediately after being removed from a cooling source, such as a freezer. In this manner, thetherapeutic modules 120 conform to the area to be subjected to atemperature treatment 305, without the need for a subdividing deforming force and without the need, for example, to wait for thetherapeutic pack 100 to at least partially thaw. - Further, it is believed that the ability of the
therapeutic pack 100 to conform to the area treated 305, helps thetherapeutic pack 100 to stay on any area to be treated, for example, the injured portion of the human body. In addition, abag 110 of a material that drapes under the weight of thetherapeutic pack 100 itself allows the therapeutic medium to come to rest adjacent to the entire surface to be treated, including reentrant curvature on the surface, depending on the size and shape of each of the plurality oftherapeutic modules 120.
