{L0 is arbottom ple n view-thereof n ry n -w n n i f re i nree vigiekan intermediate-body portion ofihighlylela s mew??? tic material, such'as rubbeitelatex-ormnetof the 1 3 portions which are rendered inelastic providing tabs which may be grasped by the fingers providing a convenient means for manipulating the dressing when attaching the same to the wounded member of a patient.

More specifically, as shown in the accompanying drawings, throughout which like parts have been designated by like reference characters, the dressing includes a composite strip, the center portion ID of which may be constructed of rubber, latex or any of the synthetic compounds having a high degree of elasticity. This elastic center or mid portion will preferably be made in various lengths and widths adapting the device to be used to dress various sizes and types of wounds. At opposite ends of the elastic portion, there are non-elastic portions ll. These are preferably provided by uniting with the elastic in these zones a layer of fabric l2.

Preferably, the bond between the fabric and rubber is effected during the curing of the rubber and in such a manner that a continuous layer of rubber is provided on the under side, as viewed in Figs. 1 and 4, with the rubber extending into the interstices in the fabric as well as uniting with the individual fibers of the fabric. The top of the fabric remains comparatively free from the rubber, however, thus providing a relatively rough and relatively stiff surface which enables the same to be better gripped by the fingers. There is thus provided a composite strip having a center portion which is highly elastic and end portions which are inelastic and which strip has a continuous rubber underside and is provided with roughened upper end surfaces. The addition of the fabric to these ends not only reduces the elasticity of the strip at these points, but also stiifens the strip and provides more body to it which, as will be seen later, assists in securing the other parts to the strip. The amount of stiffness of the ends is a matter of choice and may be varied between relatively wide limits. Preferably, a certain amount of flexibility is desirable.

Means are provided for connecting the composite strip to the body of a patient in such a manner that the elasticity of the mid portion is utilized to apply traction through the connector means on the opposite sides of a wound. This generally comprises metal members having sharp points that penetrate into the skin. Specifically, these members may each include a fiat body portion I 5, adapted to lie fiat against the under side of the strip at a zone H, and having an end portion which curves downwardly as indicated at l6 and then turns backwardly at I! to form a transversely extending lip. The edge of the lip 11 is provided with a plurality of needle likeprojections r spicules 18, which extend toward the mid portion of the dressing.

There is thus provided a member which is generally hook shaped in longitudinal section and has sharp points. Two of these members are used in connection with each of the composite strips, being secured to the inelastic portions adjacent the elastic portion and in such a manner that the projections l8 point in the general direction of the center of the strip. These members are secured to the underside of the composite strip with the fiat part disposed adjacent the elastic zone and the bight of the hook being toward the end of the composite strip, by cementing and a clip (Fig. '7). The clip comprises a fiat strip which engages with the upper surface of thefabric 12, and-the ends of which extend around the edges of theflat body portion 15 at 2| and are then bent backward at 22 against the underside of the flat body portion l5. If desired, the bent part 2| may be notched at 23 to facilitate the bending of the clip and provide a tighter joint between the clip and the projection carrying body portion l5 to thus more securely grip the composite strip therebetween. Prior to assembly, cement is applied to the adjacent faces of the body portion l5 and the composite strip at the under side, and the body portion and composite strip brought together and held in position by the clip until the cement has an opportunity to set. After assembly, the cement and the clip both cooperate to hold the parts securely together.

It will be apparent that the point carrying metal members may be secured to the composite strip in other manners than that shown, but I have found that the means illustrated and described are very effective, economical and easy to construct.

The ends ll of the composite strip extend beyond the attaching members and provide tabs which may be grasped by the fingers or forceps for manipulation of the device. The effectiveness of these tabs is increased by having the upper surface comparatively free from rubber, which leaves a good rough gripping surface, the roughness of which depends upon the coarseness of the fabric.

The projections [8 may be provided on the edge of the lip l! in various manners. I have found that one manner of forming them is by lapping as shown in the copending application of Valentine B. Seitz, Serial No. 561,365, filed November 1, 1944, and which has become abandoned. Preferably, the projections are disposed in closely spaced relation along the edge of the lip, and as best shown in Fig. 8, and may be substantially pyramidal in form. In one case, I have found that 20 of these points per inch and each approximately .004 inch square at the base and .020 inch in length provide a very effective action. It will be apparent that the number and size may be varied. By lapping the points, they may be made very sharp, which allows them to penetrate with very little trauma. Having the points closely spaced enables traction to be evenly distributed over a wide area, and the length is so gauged as to prevent deep and painful penetration.

Fig. 5 shows the manner of application of the dressing of my invention. The body of a patient is shown at 30 and as containing a cut 3|. The cut will ordinarily be gaping but is shown nearly pulled together due to the traction exerted by the dressing.

In applying the dressing, the ends, or tabs ll, of the dressing are grasped between the fingers and pulled in opposite directions. This causes the mid portion it! to be stretched.

Preferably, the thumbs engage with theclips 20, and the elements carrying the sharp projections may thus be tilted so that the projections l8 point in a generally downward direction but still point toward the medial portion of the dressing. The projections I8 are then brought into engagement with the skin on opposite sides of the cut and the projections l 8 gently pressed into the skin and toward the wound from opposite sides while at the same time the tension on the tabs H is released. The tension exerted by the part l0 then holds the projections in the skin, their penetration, however, being limited by the length of the projections.

Because the projections are sharp, very little discomfortis experienced, nor do they penetrate "fai' 'e'riough to cause any damage to the flesh under the skin, error that matter, the ski-n itself.

As is best illustrated in Fig. 5, the skin adjacentthe projections, and between the projections and the wound, tends to heap up providing a more effective engagement therewith, and the curved struc'tu're FG'pr-ovides a clearance space preventing the projections from being displaced from their engagement by this heaping up."

' T-he "dressing, after the tabs H- are released, assumes; a: position substantially as shown in Fig. 5, the part' Hi causing th connector mean-s and their projections to'be steadily pulled in toward the wound. The placement of the proj'ections causes this traction to be distributed over a wide area with the result that considerable traction may be produced which soon draws the edges of the wound together, materially increasingthe-healing rate and speeding epithelization i by reducing the area to be epithelized.

' 'If desired, the traction can be enhanced by fastening a strip of adhesive tape over the ends H: and/or the connector means to hold the same more closely to the body of the patient.

It will be seen that the traction exerted is largely determined by the character of the rubleer;- The invention adapts itself very readily to making dressings of various widths and lengths.

It also enables the dressing tobe placed directly over the wound, and the rubber will not adhere as readily as the conventional dressings to the excretions therefrom. The material of the strip may be sufficiently transparent to allow the wound'to be viewed Without removing the dressingfIf desired, the wounded member may be wrapped with a gauze bandage for further protection andto absorb the excretions from around the edges and prevent foreign matter from enteri'ng under the edge of the dressing.

It can be seenthat the dressing may be applied in a matter of seconds, and if the user thereof is not satisf ed with the manner of its placement, it may be as quickly removed and reapplied, all without pain or discomfort to the patient. Because of itsc onstruction, traction may be applied inadirection to better close the wound, and the wound edges may be brought so close together that it is unnecessary to use a gauze bandage i e tl d e t the i d li n Fig.5, it will be noted thatthe, actual point of traction is .displaced somewhat from the edge thl'woun'd. The p oint where th traction is applied, may be varied to some extent by the length of theintermediate elastic portion. In some'instances, however, it may be desirable to apply thetractionalong close to the edge of the mi it t i QUQ the Wound t0 e closed more and also provides more skin Oneither sideof the with?! whi m e r c ed- 'I n rjigs 9'and l0, Lhaveillustrated a modified form of; the. invention which allows traction to' be applied, closer. to. th edge of. the wound apdwhich also permits greater traction to be ed, The principle difference; between this dre ing and; that of the other figuresis in the pro sion-of a, downwardly, and inwardly extendmg, nortiontll whichextends at substantially the same",anglelasthepart [land is provided with pointson spicules l 85 Thusthe, elements which are.,'secured to thefinelas'tic parts of. the compositastrip re,each provided with two sets of skin'enge'gin DQintSQQneset o fwhichis the same e; ngembodiment, the other set a nwardly. ewn, her from. n

adaptedtoi engage with tneaskin close to theedge of the wound,

Thus substantially twice as much adhesion may be realized, and traction may be applied very close to the edge of the wound which affords a still. greater amount of skin that may be stretched.

In some cases, it may also be desirable-to construct a dressing similar to that shown in Figs. 9 and 10- but with the outer set of spicules l-8 and the supporting portions l6-I I: removed and only the portion 46 with thespicules 18" remaining. It will be seen, however, that in this case it is most desirable to have additional means to hold the end of the metal member having the sharp projections from tilting, asin this structure, the tendencywould-befor the spicules- |8-' to act; as a fulcrum about which the portion 4i!- could revolve, and the dressing would thus be pulled'out of engagement.

It will alsobe seen that more than one dressing may be used if desired and in such a manner as to place greater traction in one area than another, and that it is possible to use thesedressings in such a manner that the elastic portions cross each other if desired, thus putting traction on wounds from different directions.

Having thus described my invention, 1 am aware that numerous. andextensive departures may be made therefrom without departing from the spirit or scope of my invention.
