YOUNG (lttornegS Patented Dec. ,14, 1943 UNITED lSTATES PATENT OFFICE BANDAGE AND METHOD F MAKING SAME William D. Young, Greenville, S. C. Application September 30, 1942, Serial No. 460,252 1o claims. (o1. 12s-155) This invention relates to an improved surgical bandage and method of making the same, and more especially to an article of this class designed to fit upon an injury or wound with the minimum amount of discomfort to the patient.
It is conventional practice to apply a bandage to an injury and then secure it in position by adhesive tape, tie strings, or the like. When using these securing means, the intermediate portion of the tape or string is usually positioned on the outside surface of the bandage and the ends of the tape or string are attached to the adjacent uninjured portions of the patients body. Since the bandage is usually of considerable thickness there is a tendency for the tape or tie strings to exert a much greater pressure near the edge of the bandage than at the central portion. This increased pressure is partially due to the abrupt change in the direction of pull upon the securing tape as the same leaves the bandage to be attached to the body. In' other words, the tape passes over an inward step equal to the thickness of the bandage, and consequently, the tensioned tape will press the bandage edge against the patients body with a greater force at this step than at other points to cause further injury or discomfort. After the wound is dressed, swelling lor traumatism begins in an hour or two making the adjacent tissues to the wound as sensitive as the Wound itself; consequently, the above-named steps in the bandage Will irritate surfaces of the body that otherwise would not be affected thereby.
It is an object of this invention to provide an improved bandage having tie tapes or other securing means extending from the inside contact face of the bandage. With such a construction, the tension exerted upon the securing means will produce uniform inward pressure upon all of the contact surfaces of the bandage.
It is another object of this invention to provide a bandage Ain which the tie tapes or other securing means are connected thereto in a novel manner so that the connection will more effectively withstand the tensile stresses ordinarily present in the tapes when the bandage is applied.
It is another object of this invention to provide a bandage of the class described having tie tapes extending therefrom, each of said tie tapes being folded back and forth upon itself to form a condensed batch, thereby occupying less space, and adding utility to the bandage. If desired, the adjacent layers of each batch may be releasably secured together so that the tape will not readily distend when handling the bandage.
It is still another object of this invention to provide a bandage which readily lends itself to streamlined continuous flow of production without sacrificing any of the high standards required of products of this nature.
Some of the ob-jects of the invention having been stated, the other objects will appear as the description Vproceeds when taken in connection with the accompanying drawings in which:

Referring more particularly toy the drawings, (Figures 1 to 5' inclusive) thev numeral IIJ denotes an elongated bandage strip or body portion which is usually formed from a layer of nonabsorbent material II and another layer of absorbent material I2 such as cotton or the like. The top and bottom of the assembled layers II and I2 have gauze coverings I4 and I5 respec.- tively, the side edges of said gauze coverings being seamed as at I6 and I1 to form a tubular member. When the tubular member is first formed, vthe seams` L6 and I1 are disposed inwardly from theside edges and therefore, each covering I4 will have a projecting selvage Illa beyond each seam line I6 and I1, and likewise each edge of gauze covering will have a projecting edge Ia. beyond these seam lines.
Since the cover I4 is adapted to be adjacent the wound, it is usually necessary for it to be made of a higher grade material than the cover I5 and the other side of the bandage. Therefore, by employing a two-piece tubular member, the cost of manufacture may be'materially reducedwithout aifecting the quality of the nished product. Y
If desired, the cover I4 can be made of absorbent material since it is adapted to be placed in contact with the wound surface, whereas, the cover I5 can be made of non-absorbent or even water 'repellent material to prevent external moisture Yfrom penetrating the bandage and infecting the wound.`
It will be noted in Figure 2 that the edges I4dI and I5a. are disposed on the inside of the tubular covering. These edges are directed to this position during manufacture by a special process and apparatus shown and described in my co- -pending patent application', Serial No. 467,351, filed November 30, 1942. It might be stated, however, that the edge portions |461l and I5a are initially on the outside when the tubular member is formed, but when the layers II and I2 are inserted, the tubular member is simultaneously I inverted so as to place the edges Ilia and i5a also on the inside.
`It will be further noted that the edges I4a and Ia both project away from the gauze coveringV I4 and away from the layer of absorbent material I2. In other words, the edgesy Illa and I5a are disposed alongside the covering I5 and substantially in parallel relation thereto. By thus positioning the edges Ida and Ia within the tubular covering, he edges Awill be farther removed from the contact cover I4 of the band# age. It is, of course, realized that the gauze covering I4 and the absorbent layer of material I2 Should be disposed adjacent the wound or injury; consequently, layers II and I2, as well as cover I4, will shield the wound from any injury or discomfort which might be produced by edges I4a and I5a.
Another important factor in the construction of the present bandage is in the direction in which the fibers in the layers II and I2 project. The fibers in each of the layers I I and I2 arecombed during the carding operation so as to extend longitudinally of the bandage. These fibers are all therefore substantially parallel and, consequently, when the bandage is compressed for shipment, the compression can b-e directed with relation to the bers in such a manner that the least possible permanent creasing will be produced. The compression of the present bandage and the mechanism therefor is shown and described in my co-pending patent application, Serial No. 467,354, filed November 30, 1942.
,"When the body portion II] of the bandage is positioned formed, suitable transversely disposed spaced marks I8 are placed on the face of Contact gauze covering I4. These marks are located apart from each other a distance substantially the length of a completed bandage I9 and thus, serve to indicate the position where the body portion is to be cut, as well as where the securing means for individual bandage are to be attached.
One of the most convenient methods of attaching a bandage to a patients body is hy means of suitable flat elongated tie tapes. These tie ltapes may be employed for encircling a limb of the patients body and for quickly securing the bandage in place over a Wound. It is to be understood, however, that other means may be employed such as adhesive tapes, strings, pins, or the like without basically departing from the spirit of the invention.
In Figure 3 two tie tapes 2G are shown secured to the end of the bandage I9 nearest the observer fby'a seam line 2|. These seam lines are parallel to indicating marks I8 but spaced a slight distance inwardly of the bandage therefrom, and serve to close the ends of the bandage as well as to secure the tie tapes thereto. It will be noted that the tie tape 2B extends longitudinally over the top of bandage I3 and is secured again to the body portion on each side of mark i8 by means of a pair of parallel rows of stitches 2l. These stitches, if desired, may be formed by a doubleneedle sewing machine or in any other suitable manner, but after the stitches have been formed, the body portion I, as well as the tie tapes 2|, are severed along line I8 approximately midway between the rows of stitches 2| to thus sever a bandage unit I9 from the portion I9. Of course, after this bandage unit is severed, both out ends will appear substantially the same as the near side of Figure 3.
It will be further noted by observing Figure 3 that each tie tape 20 is'folded upon itself a plurality of times to form spaced batches 22. In fact, there are -two such batches 22 in each tie tape 20, said batches being connected by a short strip of material 22a.. Also these batches of materal are releasably held together by any suitable means such as tack stitches 23, or the like. When .the bandage unit I9 has been secured as above described, each tie tape 20 has the ends thereof secured to the ends of the bandage unit and also has its intermediate portion 22a unsevered. Then the portion 22a is severed to form two tie strips 20a from each strip 2B, and at this stage, each tie strip 26a will have its end formed into a batch 22.
The next step comprises Athe binding of the ends of the unit I9 to complete the bandage. This binding also serves to additionally secure the tie strips 20a. to the ends of the bandage as well as to bind the loose fiber upon the cut ends of the bandage. Figure 5 shows the binding and tie strip construction in detail. A piece of binding material 2l is folded over the end of the bandage unit I9 and over the end of the secured tape 20a. Then, the material 21 is secured to the end of the bandage and to the tapes 28 by means of a second line of stitches 28, thereby forming a rectangular bandage having all four edges completely covered, and having the tie strips folded together in batches so that the same will occupy a minimum amount of space when handling the bandage.
Figures 6 to 9 inclusive show another form of surgical bandage 30 which is similar to the preceding form'except as to the manner in which the tie tapes are attached to the bandage ends.
"I'heiefore,h parts in this form of the invention which are identical to parts in the preceding form -will be given similar reference characters and yonly a description will be made of the parts of the bandage structure by means of seam line 2|. In the preceding form, the tape is attached in a similar manner except it is attached only on the top side' of the bandage. The next step in the formation of the present bandage 30 is to Wrap the attached tape 3| around the end of the bandage to the top side and over the seam 2|. VAfter this has been done, the binding material 2 is employed to encase both the end of the bandage and portions of the above-named tapes 3| in the manner shown in Figure 8. Then a second seam line 28 is employed for securing the binding in position on opposed sides of the bandage, and also for additionally securing the end of each tape to the end of the bandage.
This type of construction is particularly valuable where the strength of the tie tape is limited. In some cases a very thin mesh gauze is employed as a tie tape, and consequently, much difficulty is obtained in providing a dependable connection to the bandage. By causing one end of each tie tape to encircle the raw end of the bandage, and then securing the tape on opposed sides of the bandage by a pair of stitch lines, the connection is made more dependable, and therefore, the likelihood of the tie tape pulling loose is very much reduced.
In all forms of the invention, attention is called to the fact that the tie tapes are so attached to the bandage that they will form a continuation of one face of the bandage when in use. In other words, if the tie tapes on the opposed ends of the bandage are pulled in opposite directions, the tie tapes and one face of the bandage will lie substantially in the same plane. This is a very important feature, because it presents a uniform smooth contact surface against the patients body when the bandage is applied to a wound, and thereby eliminates any ridges or objectionable formations in the contact area.
To further illustrate this feature, attention is called to Figure 9. In this figure the dotted outline of a patients limb is designated by the reference character 35, and around this limb a bandage 3l! is applied. The distended tie tape 3|, that is, the unfolded batches 23, are used to hold the cover material I4 of the bandage in contact with the surface of limb 35 and suitable knots or bows Bla are employed for uniting the ends of the tie tapes. It is clearly evident that the objectionable ridges or ends of the bandage, around which the binding material 2l is placed, are positioned away from the surfaces of the limb and are thereby prevented from being a, source of annoyance when the bandage is applied. On the other hand, the pressure exerted upon the surface of the limb 35 is necessarily uniform throughout the entire area of the bandage and also throughout the engaging area of tie tapes 3l, because the tie tapes are a continuation of contact face I4. Figures 10 to 14 inclusive show still anotherI modified'form of bandage' 38, and 'also'illustrates a new method of producing the same. In this form of the invention, a layer of absorbent material 39 is placed upon a layer of non-absorbent material 40, and the two materials are encased Within a tubular fabric 4|. This tubular fabric is preferably formed from a single sheet of gauze material, which is shown and described in my copending application, Serial No. 467,351, filed November 30, 1942.
During the formation, however, the edges of the sheet material 4| are sewed together by a seam 42 at a substantial distance from the overlapped edges of the fabric, thus providing outwardly projecting edges lla which are similar to the edges Ida and |5a described in connection with the first form of the invention.
The tubular member is then turned While the layers of material 39 and 43 are inserted therein, thereby placing edges 4Ia on the inside. Likewise, the edges da extend away from the absorbent material 39 and away from the contact side of the cover material 4|, so that the edges will not irritate the patients body when the bandage is applied to the wound.
The first step in the formation of this bandage comprises the attachment of one end of a broad tie tape t3 to the opposed cut ends by means of a seam line lill in the manner shown in Figure 13. The bandage may be cut to a predetermined length before attaching the broad tie strip 43, or, if desired, by a, special process, the severing of the bandage and the attaching of the tape strips 43 by the seam may be done all in one operation. Each of these broad strips 43 has the unattached end thereof folded to form a batch 45, said batch being releasably secured in a unit by means of quickly removable tack stitches B6 or some other similar manner.
After the first attaching operation of the tie strips has been performed as illustrated in Figure 13, each strip is wrapped around the cut end of the bandage 38 and over the top of the bandage until seam llt is covered. At this time, a piece of binding material 4l is wrapped around the end of the bandage and the attached end of the tape material 43 in a manner shown in Figure 14. The binding material and the tape 43 are then secured in position upon the cut end of the bandage by means of a second stitch line 8.
If desired, both tie strips 43 may be in one continuous length with its ends first attached to the bandage structure in the manner shown in Figure 3. Then the intermediate portion of the attached strip may be reversed to the opposite side of the bandage to cause the cut ends to be encircled by the ends of the strip, after which the binders may be placed in position in the manner just described. If this latter method is used, it will be necessary to sever the continuous bandage strips approximately midway between the seams 48 and batches 45 tc thereby form a tie strip construction, such as shown in Figure 10.
The next step in forming a bandage of this type is in the provision of additional tie strips. In other words, it is desirable to have four tie strips attached to the bandage, two at each end, so as to effectively secure the bandage to the patients body. In order to quickly provide these additional strips the two batches on the respec: tive broad tie strips 43 are placed side by side and in an extended position from the body of the bandage itself, in a position substantially as shown in Figure 11. Then the batches 43 and 'the associated'tie strips are slit longitudinally substantially along dotted linesv 49, therebyform- Ying four tie strips 43a, each tie strip havinga folded batch 45a on the end thereof which batch has its folds releasably secured together by Va portion 46a of the tack stitch 45. l
This severing operation may be produced in :a number of ways such as by bringing the ma'- terial into engagement with a rotary knife 50 or some other similar cutting implement.
When the tie strips'hav'e been formed'inv the manner shown in Figure 11, the bandage is .again straightened to a substantially flat position and then two superposed batches 45a of tie strips 43a are folded longitudinally in one. direction upon the bandage and the remaining superposed batches of tie strips are folded in the opposite direction, thereby providing a better-distribution of the tie strip material Vwhich facilitates subsequent packing and compressing operations.
In the drawings and specification, there has been set forth a preferred embodiment of the invention and although specic terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being defined in the claims.
