SURGICAL BANDAGE Sidney A. Peerless and Daniel Osher, Cincinnati, Ohio Application March 21, 1955, Serial No. 495,428

6 Claims. (Cl. 128-171) This invention relates to improvements in surgical bandages of the wrap-around class, that is, bandages consisting of an elongated strip of pliable material which is wrapped about an injured part of the body.

In general, bandages of this class are utilized in dressing lacerations, minor surgical incisions and other injuries to prevent exposure to bacteria and, in many cases, to apply pressure for the control of bleeding. They are also used in treating sprains and similar injuries which require the application of pressure. The conventional bandage usually is made from surgical gauze or elastic material having sufficient length to be Wrapped or wound successively about the injured member. After being wrapped, the free end of the strip or band is anchored so as to secure the convolutions of the bandage in position. Metal fasteners, safety pins or adhesive tape commonly are utilized for this purpose. In other instances, the free end portion of the strip is split lengthwise and wound in opposite directions around the bandage or bandaged part, the free ends of the split portions then being tied together to anchor the end of the wrapped bandage. Accordingly, the common mode of attachment anchors only one end of the strip and does not provide a positive holding action.

When dressing a bleeding wound or laceration, the physician usually winds the bandage strip under moderate tension around the injured part and directly over the wound, then continues winding the strip under greater tension on opposite sides of the wound or above and below it. The strip is thus contracted under pressure about the injured part on opposite sides of the wound to restrict the flow of blood.

United States PatentO If the nature of the laceration requires a fairly tight repeat this procedure several times until the bleeding is brought under control; thereafter, the bandage may be wrapped under less tension.

In a great many instances, and particularly if the bandage is applied to an arm or leg, the bandage tends to loosen and relax after it is wrapped in place. Usually the strip is wound helically or spirally, at least in part, and the helical convolutions have a tendency to slip lengthwise of the bandage as the result of normal movements of the limb. This slippage naturally causes relaxation of pressure eventually throughout the entire bandage since the strip is anchored only at one end. The convolutions may relax to such an extent that the entire bandage slips away from its original position.

Briefly therefore, the conventional bandage is inconvenient to apply because it requires the manipulation of an attachment device or a tying operation to anchor it. The necessary attachment procedure adds to the inconvenience when it is necessary to unwind the bandage temporarily to relieve distress or to treat the wound.

Moreover, the conventional mode of attaching the baud 2,820,456 Patented Jan. 21, 1953 age is unsatisfactory because the windings tend to relax and loosen after the bandage is applied.

It has been a primary object of the present invention to provide a prefabricated bandage having a simple attachment device which anchors each winding or convolution as it is wrapped and which allows the physician to apply the several convolutions under individually regulated tension. The attachment device thus eliminates the separate attachment devices conventionally utilized and the attendant manipulation of them. By anchoring each winding individually, there is no opportunity for the windings to loosen, therefore, the bandage retains its original regulated pressure and position relative to the 1n ury.

Another object has been to adapt the bandage strip to be wrapped about one area at a given tension and to be wrapped helically to embrace other areas under greater or less tension, with the several windings overlapped and anchored individually. This is of particular advantage in dressing a bleeding Wound since the bandage strip may be wound under greater tension on opposite sides of the injury to control bleeding while the intermediate windings which bear upon the injury itself may be applied with less tension.

A further object has been to provide an attachment device which anchors the individual windings automatically as they are applied and which releases them readily as they are unwrapped. This allows the bandage to be unwound partially or completely and allows it to be rewrapped and anchored quickly and conveniently. This feature is of particular advantage in those cases which require temporary relaxation of pressure to restore circulation.

Briefly, the present invention is based upon the concept of combining a fabric strip, which is elastic lengthwise, With an integral attachment buckle having a row of spaced pointed tangs or spurs extending across the strip and projecting in the direction of the free length of the strip. Upon being wrapped in stretched condition about the injured part and over the tangs, then relaxed, the contracting strip pulls itself lengthwise toward the pointed ends of the tangs, causing them to pierce the fabric and provide a releasable anchorage for each winding as it is applied. Since the row of tangs extends across the full width of the strip, the helical convolutions which extend outwardly from opposite sides of the buckle, are engaged and anchored by at least one tang each. Upon being pierced, each winding is thus anchored to the end of the bandage strip which underlies the convolutions; hence the windings are secured in a positive manner and under fixed tension about the several zones of the injured member.

A further object of the invention has been to provide a self-contained bandage which can be applied by an injured person to enable him to help himself in an emergency. For this purpose, the self-contained bandage is equipped with an adhesive anchorage strip extending loosely from the free end of the pad opposite the elastic strip. To apply the bandage, the adhesive strip is applied with one hand to the surface of the limb or other injured part to hold the pad temporarily in position. This makes the unit particularly useful in case of an arm injury. After the adhesive strip is attached, the elastic strip is wrapped about the arm and over the pad and adhesive strip. The adhesive strip provides sufficient purchase to allow the elastic strip to be stretched and anchored to the barbs; thereafter, the additional windings are readily applied to complete the dressing.

The prefabricated bandage, with the attachment buckle (and adhesive strip) permanently secured to it, is furnished in suitable lengths and widths to accommodate 7 the various parts of the body and types of wound santl injuries. Eachhandagepreferably iSpackagedimcQmpact form, and sealed in an envelope in sterile condition for convenient application.

In. the present instance, the pad is. of two-ply formation, althoughfadditional plies may be formed if greater thickness is. desired- As indicated, the length of the folded padis approximately twicethewidth of the-bandage strip. After being. formed, the pad'is folded lengthwise upon the end portion of "the bandage strip. It is then secured by linesof stitching whichpass through the end portion of 'thes'trip.and'through the plies or..laminations of the pad; The-pad'thus is secured. permanently upon the under" surface. of fthe bandage. strip in position to be acedown uponthe. woundQorinjury when the issappliedi- The outer; endof-.pad'12..forms..an ge 1 portion which may, conveniently beheld in p'liicea'with" the. thumb onfi'nger'. while ,the first convolution is1wrapped and'anchOredQtothe barbs. Asexplainedllater iiiidttiilQtheaPad' also provides a reinforced anchorage ii fli'e clip 11.

To. prevent unraveling of. the-woven fabric, the endof the bandage strip opposite the pad is also doubled over upon itself as indicated at 13 and stitched as at 14 to provide a hem.

Referring to Figure 1, the attachment clip or buckle 11 consists of a flat, rectangular body formed of sheet metal, extending for the full width. of the bandage strip and including a row of tangs 15 spaced apart from one another and projectingoutwardly from an edge of the clip body.- To reduce weight,.themajor central portion of the clip body includes a rectangular opening 16, the body 'tliusbeingLinthe formofan open rectangular frame. Each tang consists. of a shank or neck 17 (Figure 12), joined to the edge 18' of the'clipand projecting upwardly from the plane of the clip body. The upper end of the shank curves forwardly and blends into a barb 20, which projects outwardly a substantial distance from the shank. The several barbsaof the row all; reside? above. theclip body inathe' same upwardlyv inclined: plane relative to the body.

As shown in Figuresl and '1-1, the forwardly'projecting end ofeach barb terminatessin a pointed end 21. The pointed ends preferably are slightly. bluntedv to prevent injury in case they. accidently scrape or contact other parts oflthe body after the bandage is-applied;

As explained. later with reference to Figure 5, the clip body is clamped in flat position against the surface of the injured part" by at least one convolution of. the bandage. strip-which is wrapped about'the part andover uponthepad. The: clip. body thus:actsas a firm baseor foundationf'or the tangsand the upward inclination. of the barbs' facilitates theanchorage of the windings as'they are passed across the barbs in stretched condition and then:relaxed (-Figures12 to 14*).

The-clips are fabricated preferably from stainless steel sheetsby a blanking andstamping operation, this material being: preferred because it resists'corrosionand does not require plating-and polishing. The clips may be blanked out in flat condition, then the tangs are bent by the stamping die'toform the shank and barb configuration.

Referring to Figuresl and 3, the clip 11 resides between-the laminations-ZZ. and'23 of the pad with itsedge 18-engaged against-folded edge 24 of the-pad,.w-ith the barbs projecting upwardly and forwardly through the doubled-edge. of the pad'and'thr-oughthe strip of bandage material above the-pad. The. clip is secured permanently in this position by a'line of-crossstitching 25, extending along. the rearward edge 26 of the clip. The line of stitching 25 passes through the' portion of the strip above the: pad and through the laminationsof. the pad: itself. Theclip is-thusanchored longitudinally of the strip be tween the row of' stitching and the folded edge of the pad. Two longitudinal linesof stitching, 2727' are appliedalong the opposite side/edges of-the: pad, passing through the strip; and pad to anchor. the clip transversely andto secure the pad morefirmly to theastrip. A. second line of stitching 28 preferably iswapplied across the opposite doubled end of the pad.

It willbe seen in Figures-3 and 12; that the barbs-20 of the assembled-bandage are spacedupwardly abovethe top-surface of. thebandagestrip withtheir pointed ends 21 projecting forwardly-and upwardly toward the opposite end'ofthe strip. When the. strip is:stretched lengthwise and wrapped about theinjured part: and overthe barbs, the. points of the barbs project in the direction-inwhich the strip is stretched;.therefore-, as the strip. israllowed to contract, it draws itself lengthwise toward the pointed ends, causing them to pierce the strip andanchor the convolution .in stretched condition.

The elastic bandage-strip preferably consistsofwoven fabric .or. webbing, having warp. threads 30 extending longit udinally of the:strip,.interwoven with crossthreads 31 formin'ggthewoof of. thefabric (Figure llll. To impart elasticitlh the fabric includes theelastic threads 32. which extend parallelwith thewarp'threadmthe elnsticthreads being interwoven in the fabric by the cross threads. The

fabric is normally contracted lengthwise by the elastic threads which are incorporated in the weave under tension. In the present example, the elastic threads consist of strands of rubber which are covered by a wrapping of fine thread, such that the exposed surface of the woven fabric is fibrous.

The fabric strip is woven rather loosely with the cross threads 31 spaced apart from one another. In normal condition, the prestressed elastic strands naturally contract the fabric lengthwise, reforming the loosely woven web into a solid pattern with the cross threads closely spaced and the longitudinal warp threads buckled between them. When the strip is stretched lengthwise (Figure 11), the Warp threads are drawn to their full length and the cross threads are separated from one another, providing interstices through which the pointed barbs 20 readily may pass. To protect the patient, as noted earlier, the pointed ends of the barbs preferably are blunted; however, the loosely woven fabric is readily pierced by the blunted barbs.

In applying the bandage to an injured part of the body, for example, an arm, as shown in Figure 5, the pad 12 is placed face down upon the injury and is held temporarily in this position. The free length of the bandage strip is now stretched outwardly and wrapped in tension around the injured part and over the pad. It will be seen that the pointed barbs reside above the surface of the pad with their pointed ends projecting at an angle upwardly and in the direction in which the strip is stretched.

The stretched portion of the strip thus passes across the top of the barbs and at an angle across their pointed ends (Figure 12). The tension on the strip is then relaxed partially, causing the convolution, particularly that portion which overlies the barbs, to contract and draw itself against the pointed ends of the barbs in the direction indicated by the arrow in Figure 13. This causes the pointed barbs to penetrate the interstices of the fabric material and thus anchor the strip in stretched condition to the shanks 17 of the barbs (Figure 14). The pad thus is secured in position by the first convolution or winding 33 (Figure 5), which encircles the limb under regulated tension. In other words, the convolution is anchored to the end of the strip by the barbs.

Application of the bandage is completed by repeating the operations of wrapping the stretched strip around the injured member and anchoring each convolution individually upon the barbs in the same manner. It will be understood that the pressure to be applied about the injured part is regulated by the amount of tension which is applied to the strip each time it is wrapped around the part and anchored.

In applying the bandage to a wound to control bleeding, as indicated earlier, the pad is placed upon the wound and the bandage strip is wrapped to cover the pad at a given pressure and is wrapped at a greater pressure along the injured part on opposite sides of the pad. Thus, as shown in Figure 5, the winding or windings 33, which overlie the pad, are each anchored to the barbs, then the free length of the band is wrapped in helical fashion as indicated at 34. It will be noted that the helical convolutions are anchored to the tangs near the outer edge of the pad, the outermost winding having an edge portion anchored by at least one tang.

Preferably, the helical convolutions are stretched at greater tension than the intermediate convolutions 33, which overlie the pad, to provide greater compression around the injured part on opposite sides of the wound. After the winding of the strip at one side is completed, the strip is wound helically across the pad (Figure 8) to the opposite side and the same procedure is followed.

'It will be observed that by anchoring each winding individually, moderate pressure may be applied directly upon the wounded area and greater pressure in the areas on opposite sides of it by controlling the pressure of the helical windings. Moreover, there is no opportunity for the helical convolutions to shift, accordingly the original 6 pressure and position of the windings remain constant in spite of muscular action and other factors which tend to loosen or displace the bandage.

Since the windings are anchored upon the barbs by contraction of the stretched strip, they are released from the barbs in a convenient manner by stretching the anchored end portion. of the strip outwardly. Upon being stretched, the strip is drawn outwardly from the shanks toward the pointed ends of the barbs and disengaged therefrom. The first winding is then unwrapped and successive windings are released in the same manner until the entire length of the strip is disengaged and unwound.

The tangs thus eliminate the manipulation of separate attachment devices and, on the other hand, the discomfort of stripping off adhesive tape, which is otherwise used to anchor conventional bandages. Because of the ease in which the windings may be released and rewound, it is a simple matter to unwind the bandage partially or completely to relieve distress, and to replace the bandage after relief is obtained.

As noted above, the buckle or clip 11 provides a very firm base or anchorage for securing the windings under permanent tension. After the first winding or windings are anchored to the clip, the helical windings 34, which are anchored to the side portions of the clip can not disturb the clip or tend to rotate it relative to the pad because of the width of the clip and its secure attachment by the lines of stitching.

The prefabricated bandage is ideal for emergency use, particularly in the case of a bleeding Wound which requires quick application of a pressure dressing to control hemorrhage. In other words, it is self-contained and requires no separate dressing material to be placed over the wound; moreover, it is self-holding, requiring no manipulation of fastening devices.

These advantages also make the bandage ideal for attaching splints to an injured or fractured limb. In this case, the first winding or windings may be attached directly to the limb and anchored to the clip. Thereafter, the splints may be held in position with one hand and the successive wrappings applied with the other hand under tension around the limb and over the splints, each winding anchored to the clip as indicated.

For purposes of illustration, the present self-contained bandage is disclosed in its application to an injured arm. However, it will be understood that bandages having proportions suitable for other parts of the body are contemplated. By way of example, for dressing wounds or injuries of the larger parts of the body, such as the waist or chest, a bandage having a proportionally greater length and width is furnished. However, the principle and mode of application of the various sizes of bandages is identical.

In the modification shown in Figures 15 and 16, an adhesive strip 35 extends outwardly from the free end of the pad. In its preferred form, the adhesive strip consists of an extension of the elastic strip 10, having a coating of pressure sensitive adhesive 36, preferably on one side only. The adhesive coating is applied to the side of the strip which is placed face down upon the surface of the injured part when the pad is applied over the wound or injury. In the preferred construction shown in Figure 16, the free length of adhesive strip is obtained by folding the laminations of the pad 12 in zig-zag formation as at 37, instead of doubling them over in the same direction (Figure 3). The zig-zag folds are secured by the lines of

stitching

25, 27 and 28 previously described, the clip 11 being anchored between the laminations by the stitching.

The modified bandage arrangement is useful as a self-' applied bandage for emergency use, particularly in dress-' ing a wounded arm which leaves only one hand free. In applying the bandage in such cases, the pad is placedface down over the wound, thus exposing the adhesive side 36 of the strip to the surface of the arm near the injury. The adhesive strip is then pressed down upon the. armto secure adhesion; this is readil'yiaccomplished with the free hand. The elastic strip is next wrapped about the arm, passing over the adhesive strip and'pad'; it is. then anchored to the barbs by stretching the free length of elastic strip andallowing it to contractand be pierced by the barbs.

The tackiness of the adhesive coating provides an adhesive purchase which is greaterthan the pull exerted by, the elastic strip when it is stretched outwardly. The adhesive strip thus makes it possible toanchor the pad tema porarily with one hand and then, with the same hand, to wrapand anchor the first winding. After this is accomplished, the function of. the adhesive strip is ended; the first winding anchors the bandage and pad for convenient wrapping of the additional helical windings with one hand.

For packaging the bandage, the strip or band of materialmay either be rolled or foldedupon itself andiupon the pad to provide a compact mass. Preferably, the. bandage is sterilized after fabrication and may. be inserted in packed condition. into asterile envelope whichv is sealed to prevent contamination.
