The present invention relates generally to therapeutic devices. More specifically, the invention relates to a therapeutic pressure band for applying pressure to a mammalian limb. Particularly, the invention relates to a therapeutic pressure band for applying pressure across muscles near the insertion point of those muscles (i.e., near where the muscle inserts into the bone) and/or across the bone itself. Such devices are commonly used to provide pain relief for inflamed and painful muscles, tendons and joint capsules and are especially used for treating medial tibial stress syndrome, also known as “shin splints.”
The pathological condition generally known as shin splints afflicts many people. In many instances, shin splints (and other forms of tendonitis) is caused by overexertion and overloading of a muscle group during exercise, sports or simple repetitive motion. For example, if a person begins running extended distances after not running for a period of time, the tendons and muscles of the person's legs, especially the gastrocnemius, soleus, and plantar muscles, may be unable to absorb the impact of the shock force as they become fatigued. In particular, repetitive stress of the impact forces may eccentrically fatigue the soleus and create repeated tibial bending or bowing. In some instances, pressure across the tibia, and in some cases the fibula, will increase to a point where the bone will be painful as well.
Orthopedists observe that many patients having various forms of tendonitis and/or muscle inflammation, and particularly those having shin splints, experience pain relief when pressure is applied across the inflamed muscles, tendons, and bones. For those patients with shin splints placing a compressive band around the lower leg between the knee and ankle may provide some relief. Such bands are also utilized during use of the leg (e.g., jogging or repetitive movement at work) to dampen muscle movement and thereby reduce additional inflammation of the muscles and tendons.
However, the mammalian body is a very dynamic system. Treatments, braces, and straps that provide relief for one patient often do not provide relief for another, which is one reason there is such a large number of orthopedic devices on the market for all types of orthopedic conditions. Accordingly, there is a continuing need for new and innovative orthopedic devices to provide treatment and relief to those patients that do not respond to known treatment methods.
In one aspect, the invention is a therapeutic pressure band for applying pressure to a limb. The pressure band comprises a plurality of flexible straps for encircling a limb and a connecting material extending between each adjacent strap to secure the straps together. The straps each have adjustable cooperative fasteners proximate their ends for adjustably fastening the straps about the limb. A plurality of elongated pressure members are attached to the band and positioned between the adjustable cooperative fasteners. Each flexible strap includes one elongated pressure member attached thereto, and the pressure members are separated from each other by a distance and oriented substantially perpendicular to a longitudinal axis of the limb. During use, each pressure member creates a discrete line of pressure across the limb.
In another aspect, the invention is a method of simultaneously applying a plurality of discrete lines of pressure to a limb. The method comprises the steps of encircling the limb with a pressure band, with the band having a plurality of flexible straps and with each of the straps having adjustable cooperative fasteners proximate ends of the straps for adjustably fastening the straps about the limb. The band also has a plurality of elongated pressure members, with each of the straps having one pressure member attached thereto. The pressure members are separated from each other by a distance and oriented substantially perpendicular to a longitudinal axis of the limb when the band is in use. The method also includes the step of adjusting the cooperative fasteners of each of the straps to tighten the band around the limb thereby compressing each pressure member against the limb to create discrete lines of pressure across the limb.
A still further aspect of the invention is a method of applying a plurality of independent lines of pressure to a limb. The method comprises the steps of placing a plurality of elongated pressure members against the limb, with each of the pressure members including a force transfer surface, and wherein each of the elongated pressure members are operable to apply a line of pressure that is independent of lines of pressure being applied by other pressure members. The steps additionally include creating a plurality of circumferential compressive forces around the limb. The steps further include concentrating a portion of each of the plurality of the compressive forces at the force transfer surface of each of the pressure members.
These and other more detailed and specific features of the present invention are more fully disclosed in the following specification, reference being had to the accompanying drawings, in which:
In the following description, for purposes of explanation, numerous details are set forth, such as device configurations and movements, to provide an understanding of one or more embodiments of the present invention. Furthermore, the following detailed description is of the best presently contemplated mode of carrying out the invention. The description is not intended in a limiting sense, and is made solely for the purpose of illustrating the general principles of the invention. The various features and advantages of the present invention may be more readily understood with reference to the following detailed description taken in conjunction with the accompanying drawings.
While the invention is described with respect to various embodiments thereof, it will be understood by those skilled in the art that various changes in detail may be made therein without departing from the spirit, scope, and teaching of the invention. Accordingly, the invention herein disclosed is limited only as specified in the claims.
Referring now to the drawings in detail, where like numerals refer to like parts or elements, there is shown in
In more detail, the pressure band 10 according to embodiment of the present invention broadly comprises a plurality of elongated flexible straps 12 of sufficient length such that the pressure band is capable of encircling the limb to be treated. The pressure band 10 includes connection material 14 that extends between and connects the straps 12 together. In certain embodiments, the pressure band 10 also includes a plurality of adjustable cooperative fasteners proximate ends of the each of the plurality of straps 12 for adjustably fastening and/or securing the straps and thus the pressure band about the limb, for creating a compressive force or pressure about the limb, and for adjusting the force/pressure applied to the limb. Each of the pressure straps 12 contains a pocket 26, 26a that is integral with the strap. In certain embodiments, the pockets 26, 26A located on adjacent straps 12 are separated from each other by a distance 32. In certain embodiments, an elongated pressure member 34, 34a contained within each of the pockets 26, 26A. During use of the pressure band 10 in certain embodiments, the pressure members 34, 34a are oriented substantially perpendicular to a longitudinal axis of the limb and each pressure member creates a distinct line of pressure across the muscles and/or bone of the limb. Each element is discussed in more detail below.
Of note, some embodiments of the present invention include features similarly found in certain portions of the inventive concepts disclosed in co-pending application U.S. Ser. No. 13/731,289 filed on Dec. 31, 2012, and entitled “A DEVICE AND METHOD FOR APPLYING PRESSURE TO A MAMMALIAN LIMB,” the entire disclosure of which is herein incorporated by reference into the present application.
In certain embodiments, the pressure band 10, including portions the flexible straps 12 and the connecting material 14, are constructed of a suitable flexible material such as woven fabric, vinyl, leather, neoprene, nylon, etc. In some embodiments, the material utilized to construct the band 10 has some elastic qualities, or in other embodiments, the material is mostly inelastic. If elastic materials are utilized, then care should be taken when the band 10 is applied to a limb because elastic materials make it easier to inadvertently cut off blood circulation to a limb. In certain embodiments, the pressure band 10 is mostly made of a single material for ease of manufacture or, in alternative embodiments; it is made from a combination of materials where the materials are chosen for specific purposes. For example in some embodiments, one portion of the band 10 is formed from relatively inelastic leather while another portion is formed from somewhat elastic neoprene. In certain embodiments, a portion or multiple portions of the band 10 are formed of solid materials (e.g., thin polymer sheets) to add strength to the strap or focus pressure in a particular area.
The architecture of the plurality of straps 12 can vary considerably. In certain embodiments, the straps 12 are formed of a single layer of material, or in alternative embodiments, the straps 12 are made of multiple layers of material. If a single layer of material is used, slight adjustments in the manner of attaching the pressure members 34, 34a (discussed below) to the straps 12 are necessary. Such adjustments are well within the knowledge of those skilled in the art.
In preferred embodiments the straps 12 are formed of multiple layers as shown in
The therapeutic pressure band 10 includes adjustable cooperative fasteners proximate the ends of each of the straps 12 for adjustably fastening the band about the limb to create compressive forces or pressures about the limb and for adjusting the forces/pressures applied to the limb. In certain embodiments, such as illustrated in the drawings, a Velcro type fastener is utilized on the ends of the straps 12, including a strip of hook portion 22 on a first end and a strip of fiber loop portion 24 on a second end. In other embodiments, a single, large piece of Velcro (either a hook portion or a loop portion) extends between and connects together each of the straps 12 on their first end. As such, the second ends of each of the straps 12, which also include Velcro, are capable being fastened to the large piece of Velcro. Although Velcro type fasteners are preferred due to ease of use, in other embodiments, other types of fasteners such as buckles, snaps, latches, or the like can be used in the practice of the invention. For example, in certain embodiments, a metal or polymeric loop is attached to a first end of a strap 12 via a small tube extending across the first end of the strap, and a second end of the strap is capable of being inserted through loop and secured in place with Velcro, prongs, clasps, or the like.
As illustrated by
In one embodiment of the band 10 according to the invention the means for applying a plurality of discrete lines of pressure to a limb comprise the plurality of pockets 26, 26a that are integral to each of the straps 12. In certain embodiments, the pockets 26, 26a are formed within the straps 12, or in alternative embodiments, are formed separately and attached to the straps 12.
In certain embodiments, the manner in which the pockets 26, 26a are formed vary with the methods used to manufacture the band 10. For example, in the embodiment of the invention shown in
In the embodiment shown in
Turning now to
The pockets 26a shown in
In embodiments of the present invention, the reinforcement of the straps 12 to form the style of pockets 26a shown in
The pressure members 34, 34a used in the practice of the invention are sized to fit within the pockets 26, 26a. The pressure members are elongated to provide continuous lines of pressure that extend for a distance across a muscle, muscle group, and/or bone of a limb. Those skilled in the art recognize that the pressure (and force vectors) applied by the pressure members 34, 34a to a limb extends along lines that are generally perpendicular to the longitudinal axis of the limb.
Pressure members having a circular or hemispherical cross-section are preferred because they create a generally smooth and uniform force transfer surface (generally represented by numeral 42) when compressed against a limb. In other embodiments, other cross sections (for example, hexagonal or star shaped) are used in the practice of the invention and may provide more relief for some patients. In addition, embodiments provide for the pressure members 34, 34a to be either solid or hollow as shown in
In certain embodiments, each of the pressure members 34, 34a on the straps 12 will have similar lengths. For instance, in some specific embodiments, each of the pressure members 34, 34a will have a length within a range from about 2 inches to about 4 inches. In certain specific embodiments, each of the pressure members 34, 34a will have lengths that are about 2.25 inches, 2.75 inches, or 3.00 inches. In certain other embodiments, one or more of the pressure members 34, 34 of the straps 12 will have different lengths. For instance, in certain embodiments in which the band 10 is positioned on a user's lower leg, the pressure members 34, 34a that are positioned higher will be longer than the pressure members 34, 34a that are positioned lower. With reference to
In all embodiments of the band 10, the pockets 26, 26a are separated from each other by a distance 32. The length of the distance 32 is that which is sufficient to create a plurality of separate and discrete lines of pressure across the band 10. Stated alternatively, the pressure members do not touch or adjoin or abut to create a single, concentrated, uniform area of pressure when the band is applied to a limb. Stated in yet a further alternative, the lines of force vectors 16 created by the pressure members 34, 34a and which are directed toward the limb are separated by a distance “D” that is greater than the sum of the radii of any two adjacent pressure members 34, 34a. Stated more simply, there is a gap between adjacent pressure members 34, 34a.
Embodiments of the present invention provide for the distance between the pockets and pressure members to vary depending upon the size of the pressure members, the width of the straps, the pocket material thickness, and the size of the limb. For those bands used in the treatment of shin splints, embodiments provide for the distance 32 to range between about ¾ inch to about 2 inches or greater. In other embodiments, the distance 32 ranges between about ¼ inch to about ¾ inch. In still other embodiments, the distance 32 ranges from about 2 inches to about 4 inches. Furthermore, it is envisioned that a certain distance 32 that provides relief for some patients will not provide relief for other patients. Thus, it is expected that bands 10 that include various sizes and distances 32 will be manufactured in accordance with the practice of the invention.
As described, embodiments of the present invention allow for the pressure members 34, 34a to apply discrete lines of pressure to muscle, tendon, and/or bone of a limb. In particular, the lengths of the pressure members 34, 34a (as described above) and the separation distance between the pressure members (as described above), allow for the discrete lines of pressure to be applied to the limb in a plurality of arrangements. For example, in some embodiments, all of the band's 10 pressure members 34, 34a will be applied only to the muscles or muscle group of the limb, only to the tendon of the limb, or only to the bone of the limb. In other embodiments, one or more of the pressure members 34, 34a will be applied to the muscles or muscle group of the limb, while one or more other of the pressure members will simultaneously be applied to the tendons that connect the muscle or muscle group to the bone of the limb. In still further embodiments, one or more of the pressure members 34, 34a will be applied to the muscles, muscle group, and/or tendon of the limb, while one or more other of the pressure members will simultaneously be applied to the bone of the limb. Such varying arrangements for the application of the pressure members 34, 34a are due, in part, to the placement, length, and separation of each of the pressure members of the band 10 according to embodiments of the present invention.
Another aspect of the invention is a method of simultaneously applying a plurality of discrete lines of pressure to the muscles and/or bone of a limb such as a human leg. The method comprises the step of encircling a limb with an elongated band such as the band 10 with the plurality of straps 12 discussed above. In particular, the band utilized in the method has adjustable cooperative fasteners proximate the ends of the straps for adjustably fastening the band about the limb. The band also possesses a plurality of elongated pressure members, such as those described previously, where the pressure members are separated by a distance and oriented substantially perpendicular to the longitudinal axis of the limb when the band is in use. The pressure members are preferably retained within discrete pockets that are integral to the straps of the band as discussed previously.
The method continues by adjusting the cooperative fasteners for each of the straps to tighten the band around the limb thereby compressing each pressure member against the limb to create discrete lines of pressure across the muscles and/or bone of the limb where the lines of pressure are separated by a distance. Because each of the straps includes its own pressure member, embodiments of the present invention provide for a user to independently adjust a magnitude of the pressure applied via each the pressure members. As such, the band of the present invention is capable of applying varying magnitudes of pressure for each of its straps and pressure members, such that a user can customize the applied lines of pressure as may be required for the user's individual needs. For example, if a user applies the band 10 of embodiments of the present invention to the user's shin to treat shin splints, the user can individually adjust the amount of pressure applied to the user's leg via each pressure member 34, 34a. In more detail, if an upper portion of the user's shin is more inflamed than a lower portion, the user can apply greater pressure to the upper portion than the lower portion. Specifically, the user can adjust the cooperative fasteners of the straps 12 so that upper straps are fastened tighter than lower straps. As such, the pressure members 34, 34a associated with the upper straps will impart greater pressures, than the pressure members associated with the lower straps.
In yet another aspect, the invention is a method of simultaneously applying a plurality of discrete lines of pressure to the muscles and/or bone of a limb. The method comprises the step of placing a plurality of discrete elongated pressure members against a limb where the elongated pressure members are the same as those discussed in relation to the pressure band 10 according to the invention. When the band is in use the elongated pressure members are substantially perpendicular to the longitudinal axis of the limb and are separated from each other by a distance. The pressure members also have a force transfer surface that extends for a distance across the surface of the limb.
The method continues with the step of creating a circumferential compressive force around the limb. This step is typically accomplished by tightening the band 10 around the limb to create compressive forces similar to those illustrated in
In addition to the therapeutic pressure band 10 described above, embodiments of the present invention also include a pressure device for applying multiple types of pressure to a limb. An example of pressure devices according to embodiments of the present invention are illustratively shown in

In certain embodiments of the present invention, the pressure device 50 includes only the sleeve 52 without any straps 54. In some embodiments, such as illustrated in the drawings, the sleeve 52 of the pressure device 50 is formed in a shape of a hollow frustoconical. Thus, a material forming the sleeve 52 has an interior surface and an exterior surface. In the embodiments in which the sleeve 52 is frustoconical, an inner diameter of the sleeve is generally greater at an upper portion of the sleeve than at a lower portion of the sleeve. Embodiments provide for the inner diameter to be sufficient for the sleeve 52 to fit around the limb (i.e., an arm or a leg) of a human, such as illustrated in
Certain embodiments of the present invention, as illustrated in
The pressure device 50, including the sleeve 52, in some embodiments is constructed of a suitable flexible material such as woven fabric, neoprene, spandex, nylon, other polyamides, or combinations thereof, as described above. In certain embodiments, the material will be perforated (i.e., breathable) to increase permeability and breathability. In some other embodiments, the material utilized to construct the pressure device 50 will have some elastic qualities, or in other embodiments, the material is mostly inelastic. If elastic materials are utilized, the inner diameter of the sleeve 52 may be significantly smaller than the limb, such that the sleeve is operable to expand over the limb when in use. In certain embodiments, the pressure device 50 is mostly made of a single material for ease of manufacture or, in alternative embodiments; it is made from a combination of materials where the materials are chosen for specific purposes. For example in some embodiments, one portion of the pressure device 50 is formed from relatively inelastic fabric while another portion is formed from somewhat elastic neoprene. In certain embodiments, a portion or multiple portions of the pressure device 50 are formed of solid materials (e.g., thin polymer sheets) to add strength to the device or to focus pressure in a particular area. In some embodiments, the material of the pressure device 50 includes multiple layers that are laminated together. For example, the pressure device 50 will, in some embodiments, will be formed form a single first layer of material that includes a second layer of material laminated over both the interior and exterior sides of the first material.
In certain embodiments, such as illustrated in
As with the straps 12 discussed previously, the architecture of the plurality of straps 54 can vary considerably. In certain embodiments, the straps 54 are formed of a single layer of material, or in alternative embodiments, the straps 54 are made of multiple layers of material. If a single layer of material is used, slight adjustments in the manner of attaching the pressure members 64, 64a (discussed below) to the straps 54 are necessary. Such adjustments are well within the knowledge of those skilled in the art.
In some embodiments the straps 54 are formed of multiple layers as shown in
As illustrated by
As illustrated in
In one embodiment of the device 50 according to embodiments of the present invention, the means for applying the plurality of discrete lines of pressure to the limb include the plurality of pockets 56, 56a and the elongated pressure members 64, 64a that are integral to each of the straps 54. In certain embodiments, the pockets 56, 56a are formed within the straps 54, or in alternative embodiments, are formed separately and attached to the straps.
In certain embodiments, the manner in which the pockets 56, 56a are formed vary with the methods used to manufacture the pressure device 50. For example, in the embodiment of the invention shown in the figures, the straps 54 are formed of multiple layers of material. In such embodiments, the straps 54 are formed of the first layer 70 of material attached to a second layer 72 of material, as discussed above. The method of attaching the first layer 70 to the second layer 72 includes any method known in the art such as sewing or gluing. Those skilled in the art can pick the method of attachment that is most suitable for the materials used to construct the pressure device 50.
In the embodiment shown in
Turning now to
The pockets 56a shown in
In some embodiments of the present invention, reinforcement of the straps 54 to form the style of pockets 56a shown in
The pressure members 64, 64a used in the practice of the invention are sized to fit within the pockets 56, 56a. The pressure members are elongated to provide continuous lines of pressure that extend for a distance across a muscle, muscle group, and/or bone of a limb. Those skilled in the art recognize that the pressure (and force vectors) applied by the pressure members 64, 64a to a limb extends along lines that are generally perpendicular to the longitudinal axis of the limb.
As with the pressure members described above with respect to the band 10, pressure members having a circular or hemispherical cross-section are preferred because they create a generally smooth and uniform force transfer surface (generally represented by numeral 84) when compressed against a limb. In other embodiments, other cross sections (for example, hexagonal or star shaped) are used in the practice of the invention and may provide more relief for some users. In addition, embodiments provide for the pressure members 64, 64a to be either solid or hollow as shown in
In certain embodiments, each of the pressure members 64, 64a on the straps 54 will have similar lengths. For instance, in some specific embodiments, each of the pressure members 64, 64a will have a length within a range from about 2 inches to about 5 inches. In certain specific embodiments, each of the pressure members 64, 64a will have lengths that are about 3 inches, 3.5 inches, or 4 inches. In certain other embodiments, one or more of the pressure members 64, 64a of the straps 54 will have different lengths. For instance, in certain embodiments in which the pressure device 50 is positioned on a user's lower leg, the pressure members 64, 64a that are positioned higher on the pressure device 50 will be longer than the pressure members 64, 64a that are positioned lower on the pressure device 50. With reference to
As previously described, in certain embodiments, the pockets 56, 56a are separated from each other by a distance 62. The length of the distance 62 is that which is sufficient to create a plurality of separate and discrete lines of pressure. Stated alternatively, the pressure members 64,64a do not touch or adjoin or abut to create a single, concentrated, uniform area of pressure when the pressure device 50 is applied to a limb. Stated in yet a further alternative, the lines of force vectors created by the pressure members 64, 64a and which are directed toward the limb are separated by a distance that is greater than the sum of the radii of any two adjacent pressure members 64, 64a. Stated more simply, there is a gap between adjacent pressure members 64, 64a.
Embodiments of the present invention provide for the distance 62 between the pockets 56, 56a and pressure members to vary depending upon the size of the pressure members, the width of the straps 54, the pocket material thickness, and the size of the limb. For those pressure devices 50 used in the treatment of shin splints, embodiments provide for the distance 62 to range between about 1 inch to about 4 inches or greater. In other embodiments, the distance 62 ranges between about ¼ inch to about ¾ inch. In still other embodiments, the distance 62 ranges from about 3 inches to about 5 inches. Furthermore, it is envisioned that a certain distance 62 that provides relief for some users will not provide relief for other users. Thus, it is expected that pressure devices 50 of various sizes and distances 62 will be manufactured in accordance with the practice of the invention. Furthermore, although the distance 62 has been described above as referencing the distance between adjacent pockets 56, 56a, some embodiments provide for such distance to refer specifically to a distance between pressure members 64, 64a.
As described, embodiments of the present invention allow for the pressure members 64, 64a to apply discrete lines of pressure to muscle, tendon, and/or bone of a limb. In particular, the lengths of the pressure members 64, 64a (as described above) and the separation distance 62 between the pressure members (as described above), allow for the discrete lines of pressure to be applied to the limb in a plurality of arrangements. For example, in some embodiments, all of the pressure device's 50 pressure members 64, 64a will be applied only to the muscles or muscle group of the limb, only to the tendon of the limb, or only to the bone of the limb. In other embodiments, one or more of the pressure members 64, 64a will be applied to the muscles or muscle group of the limb, while one or more other of the pressure members will simultaneously be applied to the tendons that connect the muscle or muscle group to the bone of the limb. In still further embodiments, one or more of the pressure members 64, 64a will be applied to the muscles, muscle group, and/or tendon of the limb, while one or more other of the pressure members will simultaneously be applied to the bone of the limb. Such varying arrangements for the application of the pressure members 64, 64a are due, in part, to the placement, length, and separation of each of the pressure members of the pressure device 50 according to embodiments of the present invention.
In addition to the pressure device 50 described above, embodiments of the present invention include a method for making the pressure device. In more detail, the method includes an initial step of forming a sleeve from the material or materials previously described. The method additionally includes a step of forming a plurality of straps, with the straps including pockets for retaining elongated pressure members. In a next step, elongated pressure members are inserted within the pockets of the straps, and a first end of each of the straps is secured to an exterior surface of the sleeve. A next step of the method includes forming two or more openings on through a thickness of the material of the sleeve, with the opening positioned on an upper portion of the sleeve. In a final step, adjustable cooperative fastener components are secured to a second end of each of said straps and to said sleeve. In some embodiments of the present invention, additional steps will be included in the method. For instance, the method may include the step of attaching a second material to said material of the sleeve. Furthermore, the step of forming the sleeve will, in some embodiments, includes forming the sleeve in a frustoconical shape, such that a diameter of the upper portion of said sleeve is generally greater than a diameter of a lower portion of said sleeve.
Another aspect of the invention is a method of simultaneously applying both an area of compressive force and a plurality of discrete lines of pressure to the muscles and/or bone of a limb, such as a human leg. The method comprises the step of encircling a limb with a compressive sleeve such as the pressure device 50 with the compressive sleeve 52 discussed above. Next, the device utilized in the method has adjustable cooperative fastener components on second ends of the straps and on an exterior surface of the sleeve, for adjustably fastening the straps about the limb. The device also possesses a plurality of elongated pressure members, such as those described previously, where the pressure members are separated by a distance and oriented substantially perpendicular to the longitudinal axis of the limb when the device is in use. The pressure members are preferably retained within discrete pockets that are integral to the straps of the device as discussed previously.
The method continues by adjusting the cooperative fastener components for each of the straps to tighten the straps around a portion of the limb thereby compressing each pressure member against the limb to create discrete lines of pressure across the muscles and/or bone of the limb where the lines of pressure are separated by a distance. Because each of the straps includes its own pressure member, embodiments of the present invention provide for a user to independently adjust a magnitude of the pressure applied via each the pressure members. As such, the device of the present invention is capable of applying varying magnitudes of pressure for each of its straps and pressure members, such that a user can customize the applied lines of pressure as may be required for the user's individual needs. For example, if a user applies the device 50 of embodiments of the present invention to the user's shin to treat shin splints, the user can individually adjust the amount of pressure applied to the user's leg via each strap 54 and its included pressure member 64, 64a. In more detail, if an upper portion of the user's shin is more inflamed than a lower portion, the user can apply greater pressure to the upper portion than the lower portion. Specifically, the user can adjust the cooperative fastener components of the straps 54 so that upper straps are fastened tighter than lower straps. As such, the pressure members 64, 64a associated with the upper straps will impart greater pressures, than the pressure members associated with the lower straps. Furthermore, while the pressure members 64, 64a provide for discrete lines of pressure, the compressive sleeve 52 will provide an area of pressure around the user's limb, including in the case of treating shin splints, to the calf muscle to the back of the user's leg and the gastrocnemius, soleus, and plantar muscles to the front and side of the user's leg. The area of pressure will force the muscles in towards the leg and will also provide support and lift for the muscles. Such area of pressure (i.e., the compression) reduces the natural stress realized by the muscles, as well as provides for increased blood flow by allowing the arteries and veins within the legs to relax.
In yet another aspect, the invention is a method of simultaneously applying both an area of compressive force a plurality of discrete lines of pressure to the muscles and/or bone of a limb. The method comprises the initial step of encircling a limb with a compressive sleeve such as the pressure device 50 with the compressive sleeve 52 discussed above. The method further comprises placing a plurality of discrete elongated pressure members against a limb where the elongated pressure members are the same as those discussed in relation to the pressure device 50 according to the invention. When the device is in use, the elongated pressure members are substantially perpendicular to the longitudinal axis of the limb and are separated from each other by a distance. The pressure members also have a force transfer surface that extends for a distance across the surface of the limb.
The method continues with the step of creating a circumferential compressive force around the limb. This step is typically accomplished with the application of the compressive sleeve 52 and by tightening the straps 54 around the limb to create compressive forces, such as illustrated by in
In the drawings and specification, there have been disclosed typical embodiments on the invention and, although specific terms have been employed, they have been used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being set forth in the following claims.
