WOVEN SURGICAL BANDAGE. 7
SPECIFICATION forming part of Letters Patent No. 781,142, dated January 31, 1905. Application filed March 19, Serial No. 198,929.
To all whom it may concern:
Be it known that I, THEODORE W. HANRATH, a citizen of the United States, residing in the city of Chicago, county of Cook, and State of Illinois, have invented a new and'useful Improvement in Woven Surgical Bandages, of which the following is a specification.
My invention relates to bandages for the use of surgeons and others; and the objects of the invention are, first, to providea bandage which shall be flexible and yelding, and, second, to provide a bandage which shall not fray or ravel on the edges. I attain these objects by a bandage constructed as illustrated in the accompanying drawing, in which the single figure represents a general view of a bandage constructed in accordance with my invention,
My bandage is of any desired widtl1,and consists of a strip of fabric, preferably linen or cotton, wherein the warp-threads a run obliquely across the strip and the filling or woof threads 5 also run obliquely across the strip, approximately at right angles to the first. In consequence of this construction all of the threads terminate at the side of the bandage, and there are no threads Which run parallel with the edge.
It is impracticable to form selvagev edges on bandages, because it would make the edges too thick, the bandage too stiff and unyielding, and such selvage or hemmed edgeswould irritate the parts to which the'bandage might be applied. On the other'hand, in the ordinary cut bandages some of the threads run lengthwise and the threads at the edge are very apt to fray out, so that the edges of the bandage are not infrequently a mass of tangled threads, which must be pulled ofl or cut to enable ready manipulation of the bandage and prevent the embedding of these loose threads (either Warp .or weft) in the'affiicted parts and causing irritation. Both of these objections are obviated in the present construction, wherein all of the threads run obliquely crosswise. The bandage is smooth and even throughout, so that there are no irritating hems or selvages, and since only the ends of the threads are exposed at the edges of the bandage no loose warp-threads or frayedweft ends are present to entangle the bandage or become embedded in a suppurated wound.
Another important advantage in this new bandage lies in its great flexibility and ability to yield or bulge at any point transversely or longitudinally, so as to readily conform to the shape of the part of the body to which it is applied and also be elastic without looseness, so as to permit considerable freedom of articulation of the joints when applied to a,
joint. For example, if there is a protuberance on the body it is only necessary for the threads of the bandage to spread slightly or to work one upon the other, so as to slightly change their relative positions, and that part of the bandage over the protuberance will conform closely to it, lying smoothly over the part without drawing or distorting the rest of the bandage and without producing uneven pres lutely non-frayable, Without the necessity of providing it with selvage, hemmed, or other- Wise-treated edges. Furthermore, a bandage constructed in accordance with. my invention will stretch longitudinally and the obliquelyarranged threads will draw closely together, so that .a bandage admitting of very tight wrapping, without, however, losingits transversely elastic and conformable properties, is
What I claim as new, and desire to secure by Letters Patent, is
' An elastic, conformable, non-frayable surgical bandage; consisting of a strip of woven fabric composed of non-elastic warp and weft threads disposed at approximately right angles to one another, and extending obliquely with respect to-the length of the strip fromedge to edge thereof.
