Jacob R. Moon ORTHOPEDIC, SURGICAL, ATHLETIC AND ANIMAL BANDAGING BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to bandages and particularly to tubular knit stretch fabrics employed for bandaging and having Velcro straps for securing the bandaging.
2. Description of the Prior Art As previously set forth in U.S. Pat. No. 3,504,672, it has been the practice to use single thickness, cotton strap bandages exhibiting the character essentially of tightly woven, light weight cotton canvas. This type of bandage has normally required the use of some form of underpadding for the absorption of shock. Thus, it has been necessary first to apply the underpadding and then the bandage in both surgical and animal application. Where conventional bandage is wrapped around a changing form a considerable length of bandage is required to envelope the changing curvature. For example, in working conventional cotton bandage around an elbow, a substantial length of bandage is consumed in the process of fitting the bandage to the form of the elbow.
Prior bandages have exhibited very little stretch or elasticity and have been relatively heavy in weight. Various forms of fastening means have been employed to fasten the outer terminal end of the bandage to the body of the bandage previously wrapped. In one prior bandage, it has been the practice to sew the nap portion of a Velcro fastener to one end of the bandage and to sew the hook portion of the Velcro fastener to the other end of the bandage. After the bandage is wrapped, the portions of the bandage having the mating Velcro hook and nap portions are engaged to secure the bandage. The nature of the surface of the conventional cotton bandage is smooth and has no facility for holding the hooks of a Velcro fastener.
A much improved bandaging for animal, orthopedic protection and support, and surgical uses is provided by the invention described in the referred to U.S. Pat. No. 3,504,627. In the bandage of the prior invention the bandage is made up of a seamless, rib knit tube formed by synthetic yarn, preferably nylon, and which provides a fuzzy surface adapted to receive the hook portion of a Velcro fastener. In the prior invention the Velcro fastener strap is arranged to that it can be embedded directly into any point on the surface of the bandage and thereby eliminate the need for the nap portion of a standard Velcro fastener. Furthermore, the elastic, soft, and multiple-layer nature of the bandage of the prior invention eliminates the need for underpadding, provides inherent shock absorption, fits to changing forms, e.g. an elbow, and exhibits substantial stretch in all directions.
The bandage of the present invention incorporates the basic features of the prior invention but provides a substantial improvement when the bandage is being subjected to conditions which would tend to cause the bandage to slip out of place or to be accidentally rubbed loose. For example, where the bandage of the prior invention is wrapped around the knee or hock of a horse the bandage of the prior invention will generally remain in place and provide the advantages previously discussed so long as the horse is not engaged in racing, fast running, jumping or the like. In the latter situations the bandage of the prior invention may slip out of place in a relatively short period of use. Also, situations have arisen where athletes and senile patients, for example, accidentally rub or push the ends of the Velcro fasteners loose.
To meet the problem of slippage the present invention incorporates a nylon seamless rib knit tube providing a fuzzy surface and having one beginning end closed by a Velcro hook strap secured to the tube laterally and whose length is substantially longer than the relaxed width of the knit tube. The other terminal end of the tube is closed by a similar Velcro hook strap secured to the tube laterally and which is of substantially the same length as the relaxed width of the tube. Additional Velcro hook straps having notched free ends extending longitudinally are attached to this last end. The arrangement of these various Velcro straps allow both the base and terminal wraps of the bandage to be bonded to Velcro hooks. When in use on the leg of a running horse the bandage is substantially prevented from slipping or at least the bandage is required to be adjusted at only relatively long time intervals. The notched ends allow the additional Velcro straps to be tucked and hidden which prevents easy disengagement.
The object of the invention is to preserve the features of the prior invention while providing additional means for minimizing the tendency of the bandage to slip when in highly active use applications.
The foregoing and other objects will appear from the drawings and description to follow.
DESCRIPTION OF THE DRAWING FIG. 1 is a fragmentary side view of a knit fabric having a set of Velcro straps attached according to the invention.
FIG. 2 is a pictorial view showing the bandage on a horses knee.
FIG. 3 is a pictorial view showing the bandage on the lower, fetlock to knee, portion of a horses leg.
FIG. 4 illustrates an alternative single notched strap for the terminal end.
FIG. 5 illustrates the bandage of FIG. 4 on an arm.
FIG. 6 illustrates employment of two notched straps on the terminal end.
DESCRIPTION OF THE PREFERRED EMBODIMENTS in FIGS. 1-3, illustrating the first embodiment, there is represented a seamless, rib knit tube 10 having at one end a Velcro hook fastener strap 1 1 secured by means of stitches 12 to the starting end and the hooks are pictured facing outwardly. An important aspect of the present invention resides around the fact that the length of the Velcro strap 11 is substantially longer than the relaxed width of the tube 10. For example in one embodiment the relaxed width of tube 10 is 3 /2 inches, dimension W. The length of the Velcro strap 11 is made 6 inches, dimension L. Velcro straps are inherently stiff. Once strap 11 is secured by stitching, adhesive or the like, dimension L is maintained.
While the ordinary Velcro fastener arrangement employs separate hook and nap portions only the hook portion is required for the present invention. Tube 10 is preferably formed with a stitch formation and utilizing a type of yarn selected such that the Velcro hook fastener 11 tends to naturally engage the surface of the fabric as securely as would be the case were the strap 11 engaging the nap portion of a conventional Velcro fastener. In one embodiment, tube 10 is knit on a dial and cylinder knitting machine and is formed with a multifilament, stretch ply all nylon yarn sold by the Madison Throwing Company, of Madison, N. C. and identified as 2/ /34 representing two ends, 100 denier and 34 filaments. This particular form of ply nylon when formed into a conventional rib knit tube exhibits substantially 100 percent longitudinal stretch and 300 percent lateral stretch. When heat processed, the fabric exhibits infinite way stretch. The infinite way stretch enables the bandage to follow the exact contour of the base upon which it is wrapped and the complete elasticity provides a soft responsive support that offers virtually no impediment to movement. The fabric is relatively lightweight, e.g., approximately 5% that of conventional bandage. Various lengths and widths may be employed. A rib knit all nylon seamless tube which measures when flat and relaxed 3 A inches in width and feet in length is well suited for most horse bandaging requirements. Such stretch characteristic and lightweight when combined with the characteristic of having a Velcro hook engaging surface has been discovered to be especially suited to use as bandaging. That is, the surface has been found to be fuzzy and ideally suited to engaging Velcro hooks. While rib knit tubes of this same structure which have been knit and then heat tumbled at about 220 F. for 20 minutes to give the desired stretch characteristic are old in the art for apparel applications such as head gear bands, no one, so far as is known, has ever recognized the utility of this type fabric for bandaging and particularly when employed with a Velcro hook fastener strap in a bandage length. After the bandage has had extensive use it may lengthen say thirty percent and thus lose some of its soft stretch characteristic. However, simply by putting the bandage in an ordinary household electric drying machine sufficient heat and tumbling is produced to restore the original relaxed length and desired soft stretch characteristic. The life of the bandage is extended and it is made both washable and reusable.
With further reference to FIG. 1 it will be noted that the opposite terminal end of the tube of length W. is closed by means of a further Velcro hook strap of length W. secured by means of stitches 16 to the side of tube 10 opposite to the side to which strap 11 is fastened and with the hooks of strap 15 facing opposite to those of straps 11. In order to provide additional securing of the terminal end or terminal wrap of the bandage an additional pair of Velcro hook straps 17, 18 having free longitudinal extending ends are secured at their respective end to the tube 10 as indicated in FIG. 1 and which leaves the Velcro hooks in the major free end portions of straps l7 and 18 oriented in the same direction as the Velcro hooks of strap 15 and free to engage the outer terminal wrap of the bandage.
FIGS. 2 and 3 illustrate the bandage in use and what is intended to be shown here is that when the bandage is applied to a changing form such as a horse knee or hock as generally represented in FIG. 2 or to the lower leg or cannon bone portion the initial or base wraps of the bandage can be secured to the Velcro hooks of strap 11 which prevents or at least minimizes opportunity of slippage of the bandage during hard use such as during racing.
To explain the foregoing in more detail it may be noted that when the bandage is applied for example to the knee of a horse the beginning end of the bandage is placed so that the hooks of the Velcro strap 11 are turned outwardly and as shown in FIGS. 2 and 3 the Velcro strap 11 is running substantially lengthwise of the leg member being bandaged. While holding the Velcro strap 11 oriented in this manner and tensioning the bandage the first wrap of the bandage is taken around the member and then is placed so that a small edge portion of the underside of the first wrap engages the hooks of the Velcro strap 11. This bonds the first wrap to the strap 11. The second wrap is arranged in the same manner in that a small edge portion of the underside second wrap is bonded to the hooks of the Velcro strap 11. It has been found that by continuing to tension and wrap the initial or base wraps of the bandage so as to have edge portions of the initial wraps engage the hooks of the Velcro strap 11 that on an average size horse up to six wraps or more of the base wraps can be bonded to the Velcro strap 11. The remaining wraps are then taken and upon forming the terminal wrap the Velcro hooks of strap 15 will now be facing towards the member being bandaged and towards the outer fuzzy surface of previous wraps so that the Velcro hooks of strap 15 can be firmly embedded and held secured. Likewise straps l7 and 18 will be oriented so that their Velcro hooks also face the outer surfaces of the prior wraps and are also adapted to be embedded in the outer fuzzy surface of these wraps.
Both in the case of the applications illustrated by FIG. 2 as well as in the case of the application illustrated by FIG. 3, it has been found that the bandage of the present invention will remain securely in place even under very severe use conditions such as when the bandaged horse is running, jumping or the like.
It will of course be understood that FIGS. 2 and 3 merely illustrate two possible applications of the improved bandage to animal use. By making the bandage of the present invention in other widths and lengths it can be seen that it is adaptable to many and varied animal, orthopedic protection, orthopedic support, surgical and athletic situations.
For use with senile patients and for athletic activities, the embodiment of FIGS. 4, 5 and 6 provide hidden terminal end straps and which has been found to be uniquely adapted to those uses where protection, support and prevention of accidental disengagement of the outside securing Velcro strap ends are all considerations in using the bandage. In either case the bandage of the invention gives uniform pressure and support, readily responds to movement of the body member on which it is wrapped, exhibits a minimum tendency to slip or creep on such member and resists being rubbed or pushed loose.
FIG. 4 illustrates a bandage of the type shown in FIG. 1 with the exception of having only a single free end terminal strap 19. Single strap 19 has a notch 20 adjacent the free end. The notched end, in use, may be tucked beneath the outermost layer of bandage (See FIG. 5) such that accidental loosening of the terminal strap is prevented or minimized, while remaining flat.
FIG. 6 illustrates a third bandage embodiment which utilizes a pair of notched terminal end straps 21, 22. Straps 21, 22 have inwardly facing notches 23, 24 respectively and which are employed in the same manner as the FIG. 4 and 5 bandage straps.
In each embodiment, it will be noted that the bandage is devoid of the usual mating Velcro straps and requires only the hook type Velcro strap. In each embodiment the laps can all be bonded together. In the embodiments of FIGS. 4, 5 and 6 the bandage has the additional feature of being able to have the strap ends effectively hidden and locked around the final lap. Thus, if the athlete, senile patient or horse caretaker is using such a bandage there is minimum opportunity to dislodge the outer Velcro strap ends.
