The invention generally relates to a wound and bandage protection system that is designed to resolve many issues of durability, comfort and ease of application that are not adequately resolved by current wound and bandage protection systems. The invention also relates to a method of using the wound and bandage protection system for wound care.
Traditional solutions for wound care involve use of gauze and bandages affixed to skin with adhesive, which need to be replaced completely when redressing the wound. This type of wound dressing has numerous shortcomings, in particular for animals with fur. Bandages affixed with adhesive restrict patient movement, and are uncomfortable. Removing the adhesive from skin can be painful, and removing it from fur is not only uncomfortable for an animal, but is also time consuming, and therefore very impractical. However, veterinarians and pet supply stores today almost exclusively sell or use bandages designed for humans for purposes of pet wound care.
One alternative for wound care are self-adhesive wraps that adhere to themselves via a sticky adhesive quality of the wrap material, without sticking to skin or fur. However, a major drawback of these bandages is that they lose the ability to stick when wet or when dirty. The wraps can become undone and unusable in a matter of seconds if licked or tampered with. Therefore, while a good solution for human wound care, these wraps are still impractical for pet wound care.
An additional reason for the need for a comfortable bandage for animals is because they are very prone to infection when healing from a wound, due to the instinct of the animals to lick the location of the wound, leading to the introduction of bacteria and germs to the wound. The animal will also lick and possibly gnaw on bandages as well. Dogs, for example, like the taste of adhesive. The current solution of veterinarians is to place a cone collar around the animal's neck. However, the cone is big, cumbersome and a nuisance for both pet and owner. A dog will swing its head wildly while trying to get the collar off. In the process they can injure themselves; they also find it difficult to navigate when moving about. They also bang into things and knock down everything that is not attached. The cone is a very unpleasant solution.
Therefore, there is a need for a bandaging system that reduces pull on skin and fur, will attach quickly and effortlessly, stay on securely, and be removable and exchangeable without pain.
Furthermore, throughout the history of bandage making, a common problem has plagued the adhesive bandage industry. In order to properly protect a wound, it should be covered and insulated from outside infectants. However, most adhesive bandages do not adequately protect a wound when applied. Makers of older bandages tried to size the gauze pad to allow for a thin strip of adhesive around the gauze pad to adhere to the skin around the wound. However, the strip of adhesive around the gauze pad would often buckle or come loose altogether, and not keep the wound properly sealed, and possibly cause discomfort. Recently companies have tried other solutions. Band-Aid® brand has given up on sealing the wound and has extended the gauze to the edge of the adhesive to maximize the amount of gauze available to cover the wound. Nexcare® has created bandages with extremely small gauze in relation to the bandage, allowing for a better seal, but providing less gauze in the exchange. Furthermore, these bandages tend not to perform well on joints, where the areas of adhesive do not conform to the bending of the limbs without causing a large amount of buckling of the gauze. Therefore, there is a need for a bandaging system to prevent buckling and loosening of the adhesive around the gauze pad of an adhesive bandage, particularly with regard to application of bandages to joints, while at the same time maximizing the amount of gauze available to cover the wound.
The present invention provides a wound/bandage protection system and a method of use thereof. An exemplary embodiment of a super-stretch tube according to the present invention is disclosed.

According to one exemplary embodiment of the invention, the stretchable material of the tube body portion 2, when extended to its full capacity, can stretch to more than double the tube body portion's 2 un-extended size. In the context of this application, “super stretchable” material refers to material that can resiliently stretch to a length that is equal to or greater than one and a half times the length of the material when not under tension. In the context of this application, “stretchable” material refers to material that can resiliently stretch to a length that is at least ten percent greater than the length of the material when not under tension. A material that has “little or no stretch” is one that is not super stretchable. A material that has “no stretch” is one that is not stretchable. A “dead zone” is an area of material that has little or no stretch which may, but not necessarily, be an integral part of an otherwise stretchable material. A dead zone area may be formed in an elastic nonwoven material with an ultrasonic seal, which is generally used when attaching two nonwovens together, by punching, applying pressure and then high frequency vibration, which causes nonwoven materials to melt, to an overlapping connecting portion of the two nonwovens. Alternatively, particularly when forming a dead zone in a single piece of nonwoven fabric, the dead zone may be formed by simply applying the pressure and high frequency vibration without punching. The “stretching resistance”, “elastic modulus” or Young's modulus, refers to a ratio of stretching force on a particular area along a particular axis over a ratio of change in the length of the material along the particular axis due to the applied stretching force. Thus, a material that can be “easily” stretched has a lower elastic modulus than a material that is “hard” to stretch. The stretchable material of the tube body portion 2 at least provides stretching capacity in a manner that allows a circumference of the super-stretch tube 1 to vary. The stretchable material of the tube body portion 2 may, alternatively, provide stretching capacity that allows both the circumference and a length of the tube body portion 2 to vary. Preferably, the super-stretch material of the tube body portion 2 is very thin, being less than 1/16th of an inch thick when in the un-extended position and provides some breathability as well as good water resistance.
The super-stretch tube 1 has a strip 4 that extends along a length 7 of the super-stretch tube 1 from a first open end 6 of the super-stretch tube 1 to a second open end 8 of the super-stretch tube 1 at least along an inside surface 3 of the super-stretch tube 1. The strip 4 may be positioned along or over a seam 5 that may extend the length of the super-stretch tube 1. The strip 4 has one or more threads made of a rubberized material provided in such a manner that the rubberized material threads are exposed at least on an inner side of the super-stretch tube 1. The strip 4 may be made from an elastic material used in some larger hair bands that includes rubberized material threads. The rubberized material is not necessarily exposed on the exterior side 9 of the stretch tube 1. Alternatively, the strip 4 may be comprised of stretch non-slip medical grade silicone or similar, preferably latex free, material. The non-slip silicone may be applied in a continuous or discontinuous manner to form the strip 4. Alternatively, the entire inside of the tube may be coated with low tack non-slip silicone or similar, preferably latex free, material.

The body 21 may be made of super-stretchable or stretchable material similar to the material of the super-stretch tube 1, discussed above and shown in
The body 21 has a panel 22 which may be made of material that has little or no stretch. The panel 22 is shown in
In the context of this specification, gauze, or gauze pad, refers to any material or composite of material that may be therapeutically used as a pad over a wound. For example, the gauze pad may be made of cotton or a polyester blend fabric. The fabric may be covered with a plastic porous film such as Telfa® which prevents or minimizes wound adhesion. Furthermore, the gauze pad may be backed with a film that prevents body fluids from penetrating through the gauze pad to the bandage.
The body 21 has an external non-wound facing surface and an internal wound-facing surface. Attached to the external non-wound facing surface of the body 21 proximate to the first end 21A is a fastening strap 23A. The fastening strap 23A, as illustrated in
A second strap part 27 is attached to the first strap part 23 via a second attachment region 25. The second attachment region 25 is preferably configured as a dead zone to provide no stretch and may be comprised of a composite of the material of the first strap part 23 and the second strap part 27 and may be attached by a punch and melt heat seal. Alternatively, the second strap part 27 is directly attached to the first strap part 23 without the second attachment region 25 intervening therebetween. The fastening strap 23A has a wound facing side, which may be seen in

The gauze port 112A may be used to attach different sized gauze pads 119 as well as to periodically replace the gauze pad 119 in the bandage/wound protector 110 shown in this embodiment. The gauze port 112A may be sized and or configured so as to attach to all, a substantial portion, or a small portion such as one side of the gauze pad 119.
In closer proximity to the first end 111A of the body portion 111 of the bandage/wound protector 110 than the gauze port 112A, may be a strip 112, which may be similar in configuration to the strip 4 in the first embodiment, having one or more threads made of a rubberized material that provides a moderate amount of friction interwoven in the strip 112 in such a manner that the rubberized material threads are exposed. Alternatively, the strip 112 may be made of other material that provides a frictional surface. Preferably, the amount of friction provided by the frictional surface of the strip 112 should be one that does not cause discomfort when the bandage/wound protector 110 is worn. The strip 112 could be configured so that it is not stretchable in either one or both of the length or the width directions. The strip 112 may be provided along the top non-wound facing side of the bandage/wound protector 110 and/or the bottom wound facing side of the bandage/wound protector 110. Moreover, the strip 112 may extend around sides of the bandage/wound protector 110 and along both the top non-wound facing side of the bandage/wound protector 110 and the bottom wound facing side of the bandage/wound protector 110 so as to form an annular shape.
An end region 113A of the body portion 111 extends from the strip 112 to the first end 111A of the body portion 111. A portion of the end region 113A may be tapered so as to provide a gradual diminution in the width of the body portion 111 toward the first end 111A. A tab 115 extends from the first end 111A of the body portion 111. The tab 115 may be centered along the outer edge of the first end 111A. On the tab 115 is a first catch fastening surface 113 on the top non-wound-facing side of the bandage/wound protector 110. The first catch fastening surface 113 may also extend onto the end region 113A.
Attached to the second end of the body portion 111B is a fastening strap 114A. The fastening strap 114A may be comprised of two parts. A first strap part 114 is attached to the second end of the wound/bandage protector body portion 111B and is made out of a super-stretch material which may be adapted to function as a loop portion of a Velcro®-type fastener on both the top non-wound facing side and the bottom wound-facing side of the bandage/wound protector 110. The super-stretch material of the first strap part 114 preferably provides a stretching resistance that is greater than the stretching resistance of the body portion 111. The first strap part 114 may be attached to the second end of the wound/bandage protector body portion 111B via an attachment region 115 which is preferably configured to provide no stretch. The attachment region 115 may be comprised of a composite of the material of the first strap part 114 and the body portion 111 of the wound/bandage protector 110 and may be attached by a punch and melt heat seal. Alternatively, the first strap part 114 is directly attached to the body portion 111 without an attachment region 115 intervening therebetween. A second strap part 118 is attached to the first strap part 114 via an attachment region 116. The attachment region 116 may be comprised of a composite of the material of the first strap part 114 and the second strap part 118 and may be attached by a punch and melt heat seal. The second strap part 118 has a portion 117 which includes a Velcro® hook type material on the bottom wound-facing side of the fastening strap 114A. Alternatively, the second strap part 118 is directly attached to the first strap part 114 without an attachment region 116 intervening therebetween.
In certain situations, it may be preferable to apply an adhesive bandage to a wound, particularly on joints, whose constant movement may cause the gauze to move. In those situations, according to the present invention, a “diamond gauze”, “triangle gauze” or “stretchable gauze” adhesive bandage, as discussed below, are preferably utilized as they have been found to have advantages over other bandages known in the art. One of the advantages of the “diamond gauze”, “triangle gauze” and “stretchable gauze “bandages is that they can provide superior adherence and conformability to a wound area with a maximal area of gauze, particularly for wounds on joints. The “diamond gauze”, “triangle gauze”, and “stretchable gauze” adhesive bandages may be used alone or in conjunction with the super-stretch tube in
a)-12(f) are, respectively, a bottom wound-facing view, a top non-wound facing view, two side views and two perspective views of an exemplary embodiment of a “diamond gauze” adhesive bandage 120 according to the present invention. The “diamond gauze” adhesive bandage 120 has a body portion 121 in a square shape, preferably with rounded corners, which may be made of any suitable material, preferably a stretchable and breathable material, which is known in the art to be used for adhesive bandages. A gauze pad 122 is attached to the wound-facing side of the body portion 121 of the “diamond gauze” adhesive bandage 120. The gauze pad 122 is a square shape. Alternatively, the gauze pad 122 may be configured in the shape of a diamond or rhombus. The corners of the gauze pad 122 may be rounded and the sides of the gauze pad need 122 need not be perfectly straight. For example, a side of the gauze pad 122 may be convex or concave curve or a wavy line. Corners of the gauze pad 122 are offset from the corners of the body portion 121 of the “diamond gauze” adhesive bandage 120 such that the sides of the gauze pad 122 are not parallel to the sides of the body portion 121 of the “diamond gauze” adhesive bandage 120. In other words, each of the corners of the gauze pad 122 are oriented towards a different length tangent or width tangent of the “diamond gauze” adhesive bandage 120. In regard to the “diamond gauze” bandages disclosed herein, the length and width tangents may be defined by the edges of the body portion 121 relative to the wound facing side of the body portion. Thus, where the body portion is square or rectangular the length and width tangents are not explicitly defined as they are the edges of the body portion itself. Similarly, in exemplary embodiments where the body portion has a different shape but one of the length or width tangents is contiguous with the tangent, the tangent line is not explicitly defined. Otherwise, the length and width tangents are a set of explicitly defined tangents that intersect with the edges of the bandage and form a square or rectangular shape. Also note that the terms length and width with respect to such tangents does not necessarily indicate that length tangents are longer than width tangents. Preferably, the gauze pad 122 is oriented so that each of the sides of the gauze pad 122 are parallel to a hypotenuse of an isosceles right triangle formed with two contiguous sides of the body portion 121 of the “diamond gauze” adhesive bandage 120. The gauze pad 122 may have the same center point as the body portion 121, and/or each of the corners of the gauze pad 122 may be oriented toward a mid-point of one of the sides of body portion 121. The size of the gauze pad 122 is such that the corners of the gauze pad 122 do not reach the sides of the body portion 121 of the “diamond gauze” adhesive bandage 120. The gauze pad 122 may be sized and positioned so as to substantially define four equal quadrants on the wound facing side of the body portion 121. The bottom wound-facing side of the body portion 121 of the “diamond gauze” adhesive bandage 120 may have adhesive as those used for bandages in the art. The adhesive may be applied to all or part of the bottom wound-facing side of the body portion 121 of the “diamond gauze” adhesive bandage 120. The gauze pad 122 may or may not be affixed to the body portion 121 of the “diamond gauze” adhesive bandage 120 via the same adhesive as that which is used to affix the “diamond gauze” adhesive bandage 120 to a patient.
