BLANK SURGICAL BANDAGE Filed July 17, 1929 2 Sheets-Sheet 2 W/farny Patented Apr. 5, 1932 PATENT OFFICE CARL BLANK, OF BONN-ON-THE-RHINE, GERMANY SURGICAL BANDAGE Application filed July 17, 1929, Serial No. 378,883, and in Germany July 23, 1928.

The invention relates to surgical bandages which are sterilized and prepared for immediate use, and are adapted to be folded to form smallpackages, each bandage being so constructed that when it is required for use the compress forming the main portion thereof can be'spread out by pulling two tapes or bands connected to oppositely disposed places of the compress without contacting therewith and can be applied to the part of the body 'whichis to be bound up.

According to the invention at least one strip of sticking plaster having projecting ends is stuck on the back of the bandage compress, the projecting ends being covered with strips of protective gauze in such a manner that the outer ends of the gauze freely extend beyond the ends of the plaster, and serve for undoing the folded bandage after being passed out therefrom and through the closing wrapper of the package. The ends of the strip of plaster projecting over the compress are folded back on the rear thereof in such a way that the projecting ends of the strip of gauze serving as pull tapes or bands for unfolding the package proceed from the portions of the strip of plaster disposed at the edges of the compress. The compress together with the plaster strips secured to the rear thereof and the ends of the plaster strips which are folded back are made with zig-zag transverse folds. An enveloping or closing wrapper made adhesive by pieces of sticking plaster capable of sterilization are provided 85 closes the folded body of the bandage in such a manner that the bands employed for the undoing thereof follow a winding course out through the ends of the Wrapper which preferably overlap one another. When several securing plasters are employed they are arranged in parallel strips, the protective gauze coverings of which merge on both sides into the bands or tapes employed for unfolding the bandage. When two strips of sticking plaster are employed each one thereof overaps the compress at an adhesive end oppositely directed with respect to that of the other strip.

In the accompanying drawings several consisting of fleece paper or the like which en-,

forms of bandage constructed according to the invention are illustrated by way of example Figure 1 is a perspective view of a surgical bandage made into a package provided with an outerpa-per wrapper and intended for sale, and for keeping. in stock.

Figure 2 is a View of the same package not provided with an exterior wrapper, but in a sterilized condition and ready for use.

Figure 3 is a cross section of the closed package illustrated in Figure 2.

Figure 4 is a perspective view showing the positions assumed by parts of the bandage during unfolding.

Figure 5 is a view on a'reduced scale of the rear of the bandage.

Figure 6 is a view of the unfolded bandage ready for application.

Figure 7 is a perspective view of a some- 7 what modified form of bandage package.

Figure 8 is a cross sectional end elevation of the package shown in Figure 7.

Figure 9 is a further modification of the bandage in the unfolded condition as seen from the underside.

The bandage covered by an outer paper layer 1 and ready for sale contains within a sterilized cover 2, advantageously consisting of filter paper a rectangular compress 3 con- 0 stituting the main portion of the bandage and consisting of several layers of gauze or the like. A strip of sticking plaster 4 is secured to the rear of the compress 3 by means of van adhesive layer, the end portions 5 thereof which project beyond the longitudinal ends of the compress serving for securing the latterv to the aflected part of the body. The adhesive layers 6 of the projecting ends of the strip of plaster are as usual covered b strips 7 of protective gauze of the same widt as the plaster strips. The gauze strips are provided with extensions 8 which project beyond the inner ends of the free adhesive layer of the strip of sticking plaster. The extensions 8 serve as bands for opening out the package.

In the folded condition the adhesive ends 5 are folded back lengthwise of the end edges of the compress 3 on to the rear thereof v passed out together from the package from folded parts 9 of the strip ofsticking plaster at the ends of the compress, and following a winding course around the transverse edges 10 and 11 appropriately engaging above one another. The folded longitudinal edges of the fleece paper sheet forming the sterilizing wrapper 2 are provided at both ends advan-' tageously with pieces of sticking plaster 12 capable of resisting the sterilizing heat.

\Vhen the strips 8 projecting from the sterilizing wrapper 2 are gripped by hand and pulled apart, the paper wrapper 2 is first torn along its transverse edges 10, 11 whereupon the compress 3 unfolds. When the pulling movement is continued the protective gauze 7 is gradually released from the adhesive layer 6 of the projecting ends 5 of the strip of sticking plaster, starting from the longitudinal ends of the compress 3.

This releasing action is advantageously con-.

tinued until the adhesive layer of the strips of sticking plaster is exposed to a certain extent on either side of the-ends of the compress, before the latter is applied over the wound. The compress held by means of the bands employed for the unfolding operation is made to adhere by pressing the exposed parts of the strips of plaster during the movement by which the compress is applied on the wound. After this has been efiected the protective strips of gauze may be completely pulled awayfrom the ends of the plaster band without any risk of displacement, and these ends may finally be secured on the, body by pressure.

In the modification illustrated in Figure 7 instead of the arranging closing means on the narrow side of the package, the ends 8 of the protective gauze employed for unfolding the bandage are placed together against the front surface and are passed outside be-- tween the two transverse edges 10, 11 of the sterilizing wrapper. By this means; whilst attaining approximately the same effective closure of the wrapper, the ends of the protective gauze used for undoing the Wrapper are made somewhat shorter.

According to another modification of the invention illustrated in Figure 9 which is particularly suitable as a finger bandage, two separate strips of sticking plaster 4 are so arranged parallel toone another on the rear of thecompress 3 that they project on one side only with a long adhesive end 7 The other short ends of the strips are, as indicated at 14, advantageously turned around the edge of the compress-for the purpose of producing a better connection therewith. The protective gauze covering 7 need not be made of the same width as the compress 3, but as illustrated need only be of approximately the same width as the plaster strips, whilst the ends of-the protective gauze employed for undoing the package are advantageously made of the same width as the package in order to exercise a tearing action ensuring complete release of the paper wrapper.

I claim 1. A surgical bandage in shape of a package comprising in combination a compress, two parallel strips of adhesive plaster each of which is attached to one side of the compress and engages over opposite ends there-v package comprising a compress attached to an adhesive plaster binder projecting beyond surgical bandage in the shape of a both sides of the bandage and each projecting portion thereof being covered by a strip of protective gauze having at the inner side facing the compress an extension forming a pull strip, and a wrapper enclosing the bandage, the said bandage and plaster binder being folded upon themselves and confined in the wrapper and the said gauze strip having its pull extensions extending to the exterior through the wrapper and arranged so as tobe grasped and manipulated to open the wrapper and unwind the package and apply the bandage without the necessity of touching the same.

3. A surgical bandage in the shape of a.

package comprising a compress attached to an adhesive plaster binder projecting beyond both sides of the bandage and having each projecting portion thereof covered by a strip of protective gauze, said gauze strips having pull extensions, and a wrapper enclosing the package, the compress, binder and gauze strips being folded in a zig-zag manner upon themselves and confined within the package,

and the extensions of the gauze strip pro-' jecting externally through the package in position to be grasped and manipulated to open the wrapper and unfold the package and apply the bandage without thq necessity of touching the same.

In testimony whereof I have hereunto set my hand.

CARL BLAVK.
