## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to the general field of medical devices and/or methods for cooling injured body parts to, e.g., alleviate pain and inflammation. In particular, it relates to an improved cover for ice bags; a method of providing an ice bag device with improved availability and convenience, by the use of such cover and other readily available items for the fabrication of such ice bag device, e.g., when needed; and the secure attachment of the ice bag to an injured body part, such as a limb or body trunk. It also relates to an article of manufacture that provides such cover, to the method of fabricating and/or using such ice bag device using such cover; to the provision with the cover of instructions for use that aid unskilled users to provide effective emergency assistance (“first aid treatment”) to injured body parts, and to methods of doing business that promote the availability of such covers, articles of manufacture, and methods, etc., to many more people who may need such first aid treatment.
2. Description of the Related Art
The desirability of using ice bags for thermal therapy is well accepted. Ice bags enable the user to apply cold to an injury such as a bruise or sprain without unacceptable mess. A common ice bag that is commercially available is the reusable type comprising a water-impermeable, commonly a rubber-lined, flexible bag having a tubular rigid neck and a removable cap. To use, the bag is filled with ice cubes or ice chips and closed with the cap, then the bag is applied to the bruised body part and held in place by hand.
Another type of cold pack that is commercially available is a refrigeratable gel cold pack which comprises a refrigerant or coolant gel material contained in a plastic housing which can be either flexible or relatively inflexible. By “refrigeratable” it is meant that the gel can be cooled by placing the gel in a refrigerator, used as the coolant in an ice bag, and then cooled again for a subsequent use. The gel packs are stored in a freezer for chilling or cooling and are then ready for use. Also commercially available is a chemical pack which comprises two or more pouches for separately storing chemical reactants which can be mixed to produce an endothermic cooling mixture.
A common home-use ice bag can be made using a commercially available reclosable plastic sandwich or freezer bag with a zipper seal, such as a ZiplocTM plastic bag filled with ice (Ziploc is a registered trademark of Dow Chemical Company, Midland, Mich.). By “reclosable” it is meant that the bag can be opened and closed numerous times.
One of the disadvantages of these ice bags is that they need to be inconveniently held by hand to maintain contact with the injured body part. To overcome this inconvenience, several types of ice bag devices comprising a holder for these ice bags have been created. These ice bag devices can be strapped around a body part, with, e.g., loop and hook mating VelcroTM-type fastening straps. These ice bag devices are usually of complicated design, large and bulky in size and/or expensive to produce and/or difficult to be washed for reuse.
Thus, there is a need for an improved, inexpensive and readily available ice bag device that can be used without having to be held by hand. Youth contact sport activities such as soccer, football and basketball are more and more popular. Unavoidably, some occasional bruises and injuries such as sprains accompany these activities. There is a need for an inexpensive and readily available ice bag device for such events. Such ice bag needs to be attachable to a body part, such as a limb or body trunk or head, because the injured player would likely prefer to stay to watch until the end of the game, but does not want to hold the ice bag with his or her hand for the duration of the game. Applying the ice bag device by hand not only is inconvenient, but it also can restrict the mobility if the injury is, e.g., in a lower part of the body such as in the leg or foot, and it can be awkward if the injury is, e.g., in a hard to reach body part such as on the back. It is also preferred that the cold should not reduce the skin temperature excessively since that can cause damage, e.g., frostbite. Such ice bag is preferably easily washable for reuse, or optionally disposable, because it is most likely applied to an unwashed and likely sweaty body part. Injuries that need an ice bag treatment also can happen in other types of outdoor activity such as picnicking, hiking and other outings, and/or on trips. Such ice bag device needs to be compact, not bulky, so that preferably it can fit in a first-aid box along with other first-aid items. Preferably such ice bag device is easily manufactured and used.
SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE INVENTION
In one aspect of this invention there is provided a flexible outer cover for an ice bag or cold pack. The flexible outer cover is preferably a unitary structure, typically either a sack structure (or pouch structure) with one open end or side, or a generally tubular structure with two open ends, that has rows of small apertures that permit string like members, typically shoestrings or shoelaces, to be threaded, or laced, or woven, through the apertures and then tied to attach the ice bag device to an injured body part of the user, and optionally but preferably to close the open end(s) or open side(s) of the outer cover. The outer cover is preferably rectangular or square in shape, or configuration, when flattened, said outer cover preferably having three closed (sealed) edges (two vertical and one lateral sides) and an opening on one lateral side, wherein the two sides of the outer cover that form the opening on the open lateral side and the edge of the closed lateral side opposite to the open side each has a row of n small apertures, with n being preferably an even number, more preferably being 2, 4, 6, 8 or 10, even more preferably 4 or 6, most preferably 4, and wherein said rows are preferably close to the edges of the lateral sides and parallel with the edges, and wherein said outer cover preferably has one or more vertical compartments.
As used herein, “aperture” can be, e.g., a small incision, a metallic or plastic eyelet, a buttonhole, a loop, a “tube”, or any similar structure that can at least partially surround the string like members to maintain the cover in position. Small incisions can be used, but normally require some reinforcing of the edges to prevent tearing, raveling, etc. I.e., the incision becomes a buttonhole when the reinforcement is a thread sewn around the incision and an eyelet when the reinforcement is metal, plastic, etc. The aperture can also be formed from a material that is different from the cover and attached to the cover, e.g., a loop of some suitable material like string, fabric, metal, plastic, etc. Similarly, a portion of the cover can be formed into a loop or tube and then sealed by sewing, glue, staples, etc. The aperture is preferably not a long tube, since such structures make it difficult to rapidly thread the string like members through the tube. “Clips” can also be used to form the apertures and attach the string like members to the cover. Clips are not preferred since they add to the complexity of fabrication and typically add to the weight. Furthermore, if the clips bind the string like member, it is more difficult to position the ice bag device. Simple incisions that have the edges reinforced are preferred. Since the ice bag device has at least a limited ability to slide along the string like member after it is threaded through the small apertures, it is relatively easy to position the ice bag device after the ends of the string like members are tied to attach the ice bag device to the body.
The outer cover is made at least partly of a relatively flexible substrate. The flexible substrate is typically a fabric, normally woven and/or non-woven and/or knitted, but can also be a resilient foam sheet. The outer cover can be made of material such as, but not limited to, woven, knitted, crocheted, or non-woven fabric of natural and/or synthetic fibers such as cotton, polyester, nylon, acrylic, rayon, and the like, felt, velvet, flocked material, heat-bonded plastic fiber material, such as, melt-blown, spun-bonded polyethylene or polypropylene, carded thermo-bonded polypropylene and rayon blend, solvent-laid thermally bonded polypropylene (e.g., TyvekTM by Dupont), resilient open-cell or close-cell plastic foam, porous and nonporous plastic film and/or rubber, paper, laminated materials such as laminate of rubber and non-woven layers, and the like. It is also permissible to have the outer cover be water impermeable and sealable to eliminate the need for the inner cooling pack. However, the different requirements for the outer cover and the inner pack make it highly preferable to provide both the outer cover and the inner pack. It is easier to wash the outer cover when it is fabric and it is easier to fabricate when there is no need to have it water impermeable.
The edges of the outer cover can be sealed by sewing, gluing, heat sealing, and the like or can be integral, e.g., when formed from tubular material that requires no sealing on the side (vertical) edges. The preferred material makes the outer cover of the ice bag flexible, conformable, and optionally stretchable, at least on the side that is in contact with the body. The material that contacts the body also preferably slows the cooling of the body part to avoid damage by overcooling, e.g., frostbite. However, the material should allow heat to flow from the injured body part. Optionally, the cover can comprise additional flaps that can be placed between the cooling pack and the injury. The desired effect is cooling without freezing and the cooling is preferably at a rate that produces no more pain than can be withstood by the user and which does not cause damage to the treated area.
The outer cover can most conveniently have one compartment designed to have dimensions suitable to hold one inner cooling pack comprising an at least relatively liquid (e.g., water, brine solution, or gel) impermeable inner container that contains a cooling medium, wherein said inner container is preferably and conveniently either a commercially available reclosable “zipper” or “zip lock” bag such as a food, e.g., sandwich, snack, or freezer zipper bag, as described hereinafter, or a specially made inner container of any suitable size and thickness. The outer cover can also be divided into two or more compartments, preferably vertical compartments, to hold two or more inner cooling packs. The preferred multi-compartment outer cover has two or three compartments, more preferably two compartments, especially for compact size inner packs. By “vertical compartment”, it is meant that the compartment has two vertical closed sides and at least one lateral open side that can be closed, e.g., by use of a shoelace. An ice bag device of the present invention comprising an outer cover having multiple compartments to contain two or more inner cooling packs has the advantage of distributing solid cooling media such as ice chips or ice cubes more evenly on the skin surface, and better preventing the ice chips or ice cubes from accumulating into one area, thus providing more even cooling and/or comfort.
The outer cover can be conveniently separated into two or more compartments, preferably of approximately equal size, by vertical sewn lines, glue lines or staple lines that are stitched or otherwise added into the outer cover. Preferably the compartment(s) have dimensions that can accommodate/fit the reclosable inner cooling packs comprising commercially available plastic zipper containers of the quart size or sandwich size as described hereinafter. A preferred multi-compartment outer cover has compartments of a size that is suitable to hold plastic zipper containers that are commercially available snack or sandwich bags, as described hereinafter. The outer cover that has one compartment can have larger vertical or lateral sides. In a preferred embodiment, the outer cover with one compartment has the lateral open side larger than the vertical closed side. Conversely, in another embodiment, the outer cover having more than one compartment preferably has each compartment with the lateral open side smaller than the vertical closed side. These preferred configurations are based upon the use of zipper bags with normal dimensions.
Another aspect of this invention relates to an ice bag device that can be attached to a human and/or animal body part, such as a limb or body trunk, said ice bag device comprising:
(a) an outer cover as described hereinabove;
(b) one or more preferably reclosable, liquid impermeable, inner, preferably plastic, containers, preferably rectangular or square in shape, to contain cooling media such as ice, e.g., cubes, ice chips, crushed ice, or ice and water combination, to form one or more cooling packs that can fit inside the compartment(s) of the outer cover, each inner container is preferably closed, e.g., sealed, on three sides and has the fourth side open, preferably having a reclosable closure, more preferably a rib and groove zipper closure; and
(c) a pair of loose (unattached) strings, preferably a pair of shoelaces or shoestrings preferably having narrow and hardened tips and preferably with flat body, that can be threaded, or laced, through the rows of small apertures of the outer cover to attach the ice bag device to a body part and, optionally but highly preferably to close the open side of the outer cover and then tied;
and wherein the ice-filled inner pack(s) of (b) can optionally be replaced by chilled or frozen refrigeratable gel pack(s) and/or endothermic chemical cold pack(s), when said pack(s) are available.
In particular, this invention relates to an assemblage of elements, comprising an outer cover as described hereinabove and one or more zipper bags, and a pair of shoelaces, that can be used to create an ice bag device, that is compact, e.g., can fit in a first-aid box along with other first-aid items, to be used at home or away from home, e.g., in sporting events, such as at a soccer field or basketball court, in other outings such as hikes or picnics, and/or on trips. Such ice bag device is preferably easily manufactured and/or inexpensive.
The inner container is preferably constructed of a liquid impermeable, e.g., waterproof, synthetic “plastic” material such as a polyethylene film. Such inner bag is preferably closed (e.g., sealed or an integral structure) on three sides and has the fourth side that is open but that preferably has a reclosable zipper closure, preferably an interlocking rib and groove, or male and female sealing closure, as described, e.g., in U.S. Pat. No. 3,338,284 issued Aug. 29, 1967 to Ausnit; U.S. Pat. No. 4,263,079 issued Apr. 21, 1981 to Sutrina et al.; U.S. Pat. No. 4,363,345 issued Dec. 14, 1982 to Scheibner; U.S. Pat. No. 4,829,641 issued May 16, 1989 and U.S. Pat. No. 4,907,321 issued Mar. 13, 1990, both to Williams; U.S. Pat. No. 5,009,828 issued Apr. 23, 1991 to McCree; U.S. Pat. No. 5,070,584 issued Dec. 10, 1991 to Dais et al.; U.S. Pat. No. 5,140,727 issued Aug. 25, 1992 to Dais et al.; U.S. Pat. No. 5,647,100 issued Jul. 15, 1997 to Porchia et al.; and the references cited therein.
Preferred inner containers are rectangular or square in shape. Each inner container can be defined by two sets of dimensions, namely, the outer dimension that includes the sealing closure line or part, and the inner dimension that counts only the storage area, without the sealing closure part. Each dimension is typically defined by two sides, the first side is a lateral or opening side and the second side is a vertical closed side. In use, the inner container(s) can be filled with, e.g., ice cubes, ice chips, crushed ice, or ice and water mixture, then the reclosable zipper closure is firmly pressed along the sealing closure line in order to hermetically seal the inner container(s). Preferably the sealing closure part is folded back onto one side of the inner bag before the inner bag is placed in a compartment of the outer cover, in order to maximize the cold contact surface and/or to better maintain the seal against any accidental opening due to pressure applied on the side of the ice bag device.
Preferred reclosable inner containers for use in the ice bag device of the present invention are the commercially available household reclosable plastic zipper bags for use as food containers or freezer storage bags, and sold, e.g., under the brand names Ziploc® or Glad®, or store name, e.g., Kroger®, and the like. The preferred commercially available household bags for use in an outer cover that has one compartment are the quart size bags (typically having an outer dimension of from about 17 cm×21.5 cm to about 18.5 cm×23 cm, and an inner dimension of from about 17 cm×19.5 cm to about 18.5 cm×21 cm) or the sandwich bags (typically having an outer dimension of from about 16 cm×18.5 cm to about 17 cm×18.5 cm, and an inner dimension of from about 16 cm×14 cm to about 17.5 cm×16 cm). The preferred commercially available household bags for use in an outer cover that has more than one compartment are the sandwich bags (typically having an outer dimension of from about 16 cm×18.5 cm to about 17 cm×18.5 cm, and an inner dimension of from about 16 cm×14 cm to about 17.5 cm×16 cm) or the snack size bags (typically having an outer dimension of from about 16 cm×9 cm to about 17 cm×11.5 cm, and an inner dimension of from about 16 cm×7.5 cm to about 17 cm×9 cm). Industrial zipper bags of many sizes are also available, e.g., from Lab Safety Supply, Inc., Janesville, Wis.
The inner zipper containers can be made of plastic film, preferably transparent plastic film. One common material used in the household and industrial zipper bag is polyethylene. The zipper bags that are useful as inner containers of the present invention typically have a film thickness of from about 0.01 mm to about 0.25 mm, preferably from about 0.02 mm to about 0.15 mm, more preferably from about 0.02 mm to about 0.1 mm, and even more preferably from about 0.03 mm to about 0.08 mm.
When the inner bag has the vertical side longer than the lateral side with the zipper closure, such as the case of most quart size bags, or when the inner bag has two sides having approximately the same length, such as some sandwich bags, it is preferred to place the inner bag in a compartment such that the lateral side with the zipper closure is at the same side as the lateral open side of the outer cover compartment. When the inner bag has the vertical side significantly shorter than the lateral side with the closure, such as in the case of the snack size bags, or some sandwich bags, it is preferred to place the inner bag in a compartment such that the lateral side with the sealing closure is at the same side as the vertical closed side of the outer cover compartment.
In a preferred embodiment, specially made elongated inner bags are used in compact ice bag devices with a smaller outer cover having two or more compartments. For the inner bag, “elongated” means that the inner bag has the lateral open side (with reclosable closure) that is smaller than the vertical closed sides. Thus, a non-limiting example of a preferred ice bag device comprises elongated inner bags having an outer dimension of from about 8 cm×18 cm to about 12 cm×20 cm and an inner dimension of from about 8 cm×18 cm to about 16 cm×18 cm, and an outer cover having two or three compartments that can accommodate the selected inner bag size, along with the optional shoelaces and optional outside plastic wrapper.
The ice in the inner cooling pack can be ice chips, but is preferably in the form of small pieces, e.g., pieces having a maximum dimension of at least about 1 cm, preferably at least about 2 cm, more preferably at least about 3 cm and less than about 10 cm, preferably less than about 8 cm, more preferably less than about 7 cm. Although the ice will not be in contact with the skin, it is highly preferred that the ice be hygienic and potable.
The outer cover can optionally be used to hold and apply other cold media in place of the ice-filled inner cooling pack. Non-limiting examples of such cold media include a pre-cooled gel pack, or a chemical cold pack. A cold gel pack is a refrigeratable gel cold pack that comprises a refrigerant or coolant gel material contained in a permanently sealed plastic housing which can be either flexible or relatively inflexible. The gel packs are stored in, e.g., a conventional household freezer for chilling or cooling and are then ready for use. Non-limiting examples of cold gel packs and/or coolant compositions are given in U.S. Pat. No. 3,780,537 issued Dec. 25, 1973 and U.S. Pat. No. 3,885,403 issued May 27, 1975, both to Spencer, and U.S. Pat. No. 5,148,804 issued Sep. 22, 1992 to Hill et al. Many commercially available gel packs, such as the NexcareTM First Aid Reusable Cold Pack produced by 3M Health Care, St. Paul, Minn., Ace® Brand Cold Compress Reusable and Ace Brand Hot & Cold Compress Reusable distributed by BD Consumer Healthcare, Franklin Lakes, N.J., are elongated in dimension with sizes of from about 23 cm×9.5 cm to about 27 cm×12.5 cm. When they are stored in a household freezer, they are chilled but not frozen. They can be folded in two in order to be placed in a compact outer cover with one compartment of the present invention that is designed to accommodate one sandwich zipper bag. Preferably they can be used in an elongated outer cover that is designed to accommodate the elongated gel packs, with the open side of the outer cover being a long side having rows of small apertures as described hereinbefore, each row preferably comprising from about 6 to about 10 apertures. The permanently sealed plastic container can also contain liquid water to be placed in, e.g., a freezer to form ice for use in the method and/or article of the present invention. The frozen ice contained in such permanently sealed plastic container adopts the shape of the container and has the dimension of such container, including, optionally, dimensions larger than about 10 cm.
A chemical cold pack typically comprises an endothermic chemical system comprising different chemicals which, when mixed together, undergo an endothermic reaction to reduce the temperature of the cold pack. Typically, the different chemicals are contained in separate compartments to prevent a premature reaction. The chemical cold pack is “activated” when the compartments are, e.g., connected by a certain means so that the chemicals are mixed to produce the endothermic reaction. An example of such endothermic chemical system is dry ammonium nitrate and water. Other non-limiting examples of endothermic chemical systems and/or chemical cold packs are given in U.S. Pat. No. 2,882,692 issued Apr. 21, 1959, U.S. Pat. No. 2,898,744 issued Aug. 11, 1959, U.S. Pat. No. 3,058,313 issued Oct. 16, 1962, all to Robbins; U.S. Pat. No. 2,925,719 issued Feb. 23, 1960, to Robbins et al.; U.S. Pat. No. 3,643,665 issued Feb. 22, 1972 to Caillouette; U.S. Pat. No. 3,893,834 issued Jul. 8, 1975 to Armstrong; U.S. Pat. No. 4,986,076 issued Jan. 22, 1991 to Kirk et al.; and U.S. Pat. No. 5,545,197 issued Aug. 13, 1996, U.S. Pat. No. 5,792,213 issued Aug. 11, 1998, U.S. Pat. No. 5,967,308 issued Oct. 19, 1999, and U.S. Pat. No. 6,036,004 issued Mar. 14, 2000, all to Bowen.
The optional pair of loose, unattached strings, preferably loose shoelaces or shoestrings, bootlaces, and/or draw cords, can be constructed with materials such as natural and/or synthetic fibers, fabric, leather, and the like. By loose shoestrings, it is meant the shoestrings, or shoelaces, or bootlaces, are free, separate, or are removed from the shoes, and no longer laced and/or attached to the shoes when used for the purpose of the present invention. By draw cord, it is meant a string or cord that is used to tie a hood or waistband on sweat suits, swimsuits, athletic or casual clothes, and the like.
The preferred strings for use in the present invention are shoestrings or shoelaces or bootlaces, having at least one hardened and preferably narrow tip, preferably two hardened and narrow tips at both ends of said shoestrings, wherein said hardened narrow tip is preferably from about 0.5 cm to about 2 cm, more preferably from about 1 cm to about 1.5 cm in length. Some shoestrings such as some leather strings are inherently stiff and do not need to be hardened further. However, most shoelaces made of natural and/or synthetic fibers need to have the tips narrowed and hardened for easy lacing through the rows of small apertures of the outer cover. Most commonly, the shoelace tips are made narrow and hardened by being compressed and encased by a round or oval hard plastic or metallic tube. The ends of the laces can also be hardened, e.g., by dipping said ends into a hot melt resin that hardens upon cooling. Alternatively, small pieces of adhesive tape can be wrapped around one, or both ends to provide hardened tips. One end of a band-aid can be used for this purpose.
The hardened and narrow tips of the shoestrings make it easy for the strings to be laced through the rows of small apertures of the outer cover. Thin fabrics can also be sewn into long strings and provided with hardened tips. Thick sheets of leather can be cut into thin, long strips to form shoestrings that are sturdy and often do not need to be strengthened at the tips for lacing. Preferably shoestrings have a length of from about 0.25 meter (about 10 inches) to about 2 meters (about 80 inches), more preferably from about 0.5 meter (about 20 inches) to about 1.5 meters (about 60 inches). Any type of shoestring can be used in the present invention, such as round or flat, or oval with two side edges, but the flat and thick sport shoelaces or shoestrings are preferred because they are more comfortable to the wearer of the ice bag device of the present invention. Such flat shoelaces spread the force needed to keep the ice bag device in place over a wider area, resulting in a lower pressure on the skin.
A string, e.g., a shoestring that is laced through the two rows of small apertures of the open side of the outer cover serves both as a closure for that open side and to attach the ice bag device to the body part. Thus, the need for a separate closing mechanism for the opening of the ice bag outer covers, commonly with the use of the expensive Velcro strips, as described as closures for other ice bags of the art, is rendered unnecessary. It is surprising that when a pair of shoestrings of the present invention are used to attach the ice bag device to a body part, the strings can be tied rather loosely and do not need to be tied really tightly but can still keep the ice bag device securely in place, while at the same time avoiding a constriction that can adversely affect blood flow.
In another embodiment, the ice bag device of the present invention can additionally comprise a pair of cord locks to provide a quick tying of the shoelaces and an easy adjustment of the strapping of the ice bag around a body part. A cord lock in this invention is meant a device in which the two ends of a string are extended through a passage in a body of the device, and are adapted to be releasably locked against longitudinal movement by, e.g., a movable slide element positioned within the body. Non-limiting examples of cord locks that are suitable for use with the ice bag device of the present invention are those disclosed, e.g., in U.S. Pat. No. 4,288,891 issued Sep. 15, 1981 to Boden, U.S. Pat. No. 4,328,605 issued May 11, 1982 to Hutchison et al., U.S. Pat. No. 4,453,292 issued Jun. 12, 1984 to Bakker, U.S. Pat. No. 4,675,948 issued Jun. 30, 1987 to Bengtsson, U.S. Pat. No. 4,986,076 issued Nov. 18, 1986 to Krauss, U.S. Pat. No. 5,197,166 issued Mar. 30, 1993 to Meier et al., U.S. Pat. No. 5,894,639 issued Apr. 20, 1999 to Boden et al., Des. 417,388 issued Dec. 7, 1999 to Kawahara, and references cited therein, said patents being incorporated herein by reference.
In another embodiment, the pair of shoelaces can be threaded into the rows of small apertures of the outer cover (after the outer cover has received the ice-filled inner bag(s)) to close the open end of the outer cover, and then tied into a pair of loops that serve as convenient holders of the ice bag device, if the injured person prefers to hold the ice bag device by hand to apply the ice bag device to the injury. This can be desirable if the cold causes pain when applied to the skin for longer times. Having a means for holding the ice bag without being in contact with the cold media avoids excessive cooling of the hand and thus helps ensure that the ice bag is used for a sufficient period of time to provide a benefit.
In an alternative embodiment, this invention relates to a flexible, liquid impermeable outer cover with a unitary structure to contain ice, as described herein above, but wherein the outer cover layer and the inner container layer are laminated together, said cover preferably having a sack structure with three closed sides and one open side (or open end), wherein the open side, or sides if more than one side is open, is sealable by a leak-proof zipper closure to retain the ice, and wherein the open side and the closed side opposite to the open side have extended peripheries having rows of small apertures that permit shoelaces to be threaded through to attach the ice-filled cover to an injured body part of the user. The wall of the cover is preferably made of laminated materials such as laminates of plastic and woven or non-woven fabric layers, with the plastic layer providing the liquid impermeability and the construction of the zipper closure and the fabric layer providing a degree of insulation to slow the cooling of the treated body part, to avoid damage by overcooling, e.g., frostbite. Such unitary structures are more difficult to manufacture.
The present invention also relates to a method of using loose shoelaces or shoestrings to attach an ice bag device having small apertures, to a body part, and/or to close the opening of the outer cover of said ice bag device. This method is of great value, since it permits one to carry/store only the described outer cover, optionally with one or more empty zipper bag containers, as separate item(s), yet permitting the fabrication and use of an ice bag device readily and immediately when it is needed. Shoelaces are normally available, especially at sporting events, and they have ends that can be readily threaded through small apertures. They also typically have flat sides that keep the ice bag device in place without excessive pressure.
The present invention also relates to an article of manufacture comprising one or more outer covers of the present invention, and optionally at least one other element which is: one or more empty reclosable plastic zipper containers, or one or more sealed, fluid impermeable plastic containers containing water, refregeratable cooling gel, or endothermic chemical cooling system, preferably one or more empty reclosable plastic zipper containers, to contain cooling media, that can fit inside the enclosure of the outer cover; two or more shoelaces; and/or a sealed plastic film wrapper to contain and keep said outer cover, said optional inner zipper containers, and said optional shoelaces in a hygienic, non-contaminated condition in storage; and/or wherein said article is optionally, but preferably, packaged in association with a set of instructions for use to direct the consumer how to use the cover to assemble an ice bag device, how to use the product properly, and to ensure that the consumer knows what benefits can be achieved, and how best to obtain these benefits. The sealed plastic wrapper is useful to keep the elements of the ice bag device in a hygienic, non-contaminated condition in storage and/or to prevent accidental loss of one or more of the elements. The plastic wrapper can be transparent or opaque, and can be white or colored. Preferably the plastic wrapper is transparent or marked with the contents so that the article can be readily identified in an emergency.
The present invention also relates to the association of instructions for use with the outer cover, the ice bag device, the method, or the article of manufacture described hereinabove to ensure that the method can be practiced and the cover and/or the article be used efficiently, quickly, and effectively so as to maximize the effect of the cooling treatment on an injury. The set of instructions provides the information on how to use the outer cover, the inner containers, the shoelaces, and the cooling media such as ice, as well as the cooling gel or the chemical cooling pack, to create a convenient ice bag device that provides immediate cooling to an injury.
The set of instructions provides the information on how to use the outer cover, the shoelaces that are either provided with the package or readily obtained from a pair of shoes or boots, liquid impermeable inner containers, and cooling media such as ice to create a convenient ice bag device that provides immediate cooling to an injury.
The set of instructions of the present invention preferably includes one or more of the following instructions: to direct the consumer to first fill the inner zipper container(s) with cooling media such as ice cubes, ice chips or crushed ice, then to seal the filled inner container(s), then, optionally, but preferably, to fold the sealing zipper closure back against one side of the inner zipper bag, then to place the filled inner ice pack(s) or ice bag(s) in the compartment(s) of the outer cover, then to lace the rows of small apertures of the two sides of the outer cover with a pair of shoelaces, or other string like structures, that are either provided with the ice bag device or removed, e.g., from a pair of shoes, and/or to apply the resulting ice bag device over the injured part by attaching the ice bag device to the body part by tying the ends of the pair of shoelaces.
The set of instructions can include an instruction to direct the consumer to a source of ice or cold fluid, preferably including a home refrigerator, ice boxes or ice coolers for beverages at a sport game, and/or a fast food restaurant and/or hotel or motel when one is on a trip. There is usually some ice or cold fluid, e.g., water or other chilled drink, available at sporting events.
The set of instructions can include an instruction to direct the consumer to optionally use already cooled gel pack(s) or endothermic chemical cooling pack(s) in the place of the ice-filled inner cooling pack(s).
The set of instructions can also include an instruction to direct the consumer to tie two or more short shoelaces together to form a longer string for a large body part, or when long shoelaces are not available. These instructions can also advise the consumer to thread part of each shoelace through the openings before tying if the openings are too small to allow a knot to pass. The set of instructions can have an instruction to inform the consumer of the option of threading the shoelaces into the rows of small apertures of the outer cover, after the outer cover has received the ice-filled inner bag, and tying them into a pair of loops that serve as convenient holders of the ice bag device to hold the ice bag device by hand to apply to the injury.
The set of instructions can also include an instruction to direct the consumer to keep the article of the present invention readily available, e.g., in their first-aid kit. In order to cool the injured body part, the instructions can suggest initially contacting the injured part directly with the cooling pack followed by attaching the completed ice bag to the clothing to minimize the danger of overcooling the flesh during a prolonged application. The set of instructions preferably comprises one or more of the hereinabove instructions.
To keep the compact size, in a preferred embodiment, the article of manufacture and/or the ice bag device kit of the present invention can comprise a pair of temporary, short shoestrings, typically from about 0.3 to about 0.6 meter in length. In this case, the set of instructions for use will preferably include an instruction or suggestion to direct the consumer to remove a longer pair of shoelaces that are usually available from a pair of unworn shoes, or from the pair of shoes or boots that are being worn by the injured person or another person, and use them to attach the ice bag device to a body part, while the provided shorter pair of shoestrings is used for temporarily tying the shoes or boots.
The set of instructions can be printed, e.g., on one or more of: the package, the wrapper, an accompanying instruction flyer or booklet, and/or communicated via print and/or electronic mass media, e.g., newspapers, magazines, radio, television, internet, circulars, etc., to members of sport and/or outdoor organizations, and the like.
The instructions can be in one or more languages. The instructions can be in words, or illustrative images and/or icons preferably in combination with words. It is preferable to have the instructions contain pictorial representations of the steps in preparing and using the ice bag device to supplement, or replace the written instructions when the user is not familiar with the language(s) of the instructions.
This invention further relates to an outer cover, an ice bag device and/or an article of manufacture comprising said outer cover and other elements of the ice bag device of the present invention, wherein one or more of the outer cover, the inner container(s), the wrapper, the package, and/or the set of instructions carry indicia showing, e.g., a logo, emblem, symbol, motif, sign, figure, mark, icon, pictogram, insignia, design, image, description, and/or advertisement for, e.g., a sport league, sport franchise, sport sponsor, non-profit or governmental organization, and/or for-profit commercial or industrial organization. The use of such indicia provides a measure of assurance to the user that the device is useful and not harmful, especially when the instructions are followed.
The above use of indicia can be used as part of the method of doing business in which the use of the outer cover, the article, etc., are promoted by using one or more existing associations, businesses, etc., to make, distribute, sell, or recommend the ice bag article, the outer cover, and/or the method, to provide assurance to the intended user that the device is acceptable for the intended result.
