Traumatic Amputation and Wound Dressing

Abstract

An integrated and complete dressing for the care and treatment of traumatic amputations and wounds. The traumatic amputation and wound dressing includes an oversized wound pad, an elastic bandage, and fasteners in an integrated unit for quickly and effectively treating an amputation. The elastic bandage may be attached to the wound pad such that the bandage forms an angle of about 90 degrees with respect to a vertical axis of the wound pad. The wound pad can be readily folded over an amputation and quickly wrapped with the elastic bandage. The fasteners may be attached to the periphery of the wound pad. When the dressing is applied to a stump of an amputated limb and the fasteners are engaged, the wound pad is relatively securely held in position and downward pressure is exerted on the stump. In some embodiments, the elastic bandage may also include brakes designed to prevent the bandage from unintentionally unraveling. The brakes also facilitate application of the dressing to the stump.

VI. DETAILED DESCRIPTION OF THE DRAWINGS

The present invention as illustrated, for example, in FIG. 1 is directed to a traumatic amputation dressing 100 for application on a stump of a severed or amputated limb of a human. The dressing 100 may also be used to cover burns or large pattern wound, such as shrapnel wounds. The dressing 100 includes at least one oversized wound pad 110 and an elastic bandage 120. The wound pad 110 is preferably of sufficient size to envelope the stump of a severed limb, or to cover the entire back or chest of an average sized human. Suitable wound pads have areas of about 16 inches by 24 inches, 20 inches by 20 inches, or the like. The elastic bandage 120 is attached to a corner of the wound pad 110. The elastic bandage is preferably at least 3″ to 6″ in width and several feet in length. Because the elastic bandage 120 is attached to the wound pad 110 the resulting integrated traumatic amputation dressing 100 is more readily applied to the amputation, large pattern wound, or burn.

In accordance with the present invention, as illustrated in FIG. 1, the elastic bandage 120 may be attached to a peripheral point, e.g., a corner of wound pad 110. The elastic bandage 120 may be attached to the wound pad 110 such that an angle θ of about 90 degrees is formed with respect to a vertical axis 150 of the wound pad 110. In some embodiments, the wound pad 110 also includes fasteners 140 situated along one or more sides, preferably two opposing sides, of the wound pad 110. The wound pad 110 may be constructed of gauze or other known materials, including translucent or transparent plastic materials, such as PETG, that allow individuals to see through the wound pad and therefore determine if bleeding has been stopped. The fasteners 140, which may comprise hooks, Velcro®, adhesive or the like, are designed to affix to each other and envelope the stump of the amputated limb with the wound pad 110. The fasteners 140 fix the wound pad 110 in place on the stump and also generate a downward pressure on the stump. Properly positioning the wound pad 110 and applying a downward pressure on the stump both assist in controlling bleeding. However, the dressing functions efficiently whether or not such alignment is achieved.

The dressing 100 is packaged with the wound pad 110 folded and the elastic bandage 120 rolled. In use, the wound pad 110 is unfolded and the center of the wound pad 110 is applied directly to the end of the stump. It may be desirable to align the center of wound pad 110 with the stump. Once aligned, the wound pad 110 is folded over the stump so as to form an envelope around the stump. The optional opposing fasteners 140, when included, are then affixed to each other thereby holding the wound pad 110 in place and providing downward pressure to the stump. The ends of the wound pad 110 may then be folded down around the ends of the stump and the elastic bandage 120 wrapped around the folded wound pad 110.

The elastic bandage 120 may also include spaced “brakes” disposed along the length of the bandage. The brakes may comprise Velcro®, an adhesive or the like and act to prevent the unintentional unraveling of the elastic bandage. The brakes may also act to help more effectively exert pressure on the stump by maintaining tension on the bandage during wrapping. The brakes also provide a more secure final packaging of the dressing on the amputation. An exemplary elastic bandage provided with brakes is described in U.S. patent application Ser. No. 11/745,184 which is herein incorporated by reference.

In accordance with an alternative embodiment of the present invention, as illustrated in FIG. 2, an elastic bandage 220 may be attached to a corner of a wound pad 210 to form substantially a 90 degree angle θ with a vertical axis 250 of the wound pad 210. The elastic bandage 220 may include a receptacle 260 formed on the bandage 220. The receptacle 260 may be formed by creating a pocket between two opposing pieces of material of the bandage 220, for example by placing stitches 265 along the perimeter of opposing pieces of material of the bandage 220. The receptacle 260 may contain an additional wound treatment material. The wound treatment material may include, for example, gauze for assistance with controlling bleeding and/or plastic sheeting for creating an occlusion layer over the wound. The treatment material may be applied to the wound prior to wrapping with the wound pad 210 or bandage 220, such that bleeding is better controlled and stabilization of the wound is promoted. The bandage 220 may also include one or more fasteners 270, such as Velcro®, an adhesive, or the like to further assist wrapping and packaging of the wound.

In accordance with another alternative embodiment of the present invention, as illustrated in FIG. 3, an elastic bandage 320 may be attached to a corner of the wound pad 310. However, this embodiment includes a receptacle 360 within the wound pad. The receptacle 360 may be formed by creating a pocket in opposing pieces of material of the wound pad 310, for example by placing stitches 365 in the opposing pieces of material along one or more sides. Treatment material, such as gauze or occlusive plastic, may be stored in the receptacle and applied to the wound prior to wrapping with the wound pad 310 or bandage 320. The treatment material along with the wound pad acts to better control and stabilize the wound. The bandage 320 may also include one or more fasteners 370, such as Velcro®, an adhesive, or the like to further assist wrapping and packaging of the wound.

Although the present invention has been described in terms of particular preferred and alternative embodiments, it is not limited to those embodiments. Alternative embodiments, examples, and modifications which would still be encompassed by the invention may be made by those skilled in the art, particularly in light of the foregoing teachings.

Those skilled in the art will appreciate that various adaptations and modifications of the preferred and alternative embodiments described above can be configured without departing from the scope and spirit of the invention. Therefore, it is to be understood that, within the scope of the appended claims, the invention may be practiced other than as specifically described herein.
