Description:

This invention relates to surgical dressings and more particularly to surgical dressings or bandages adapted in particular for application in substantially moist condition to a wound, such as described in and disclosed by my copending application Serial No. 429,094, filed January 31, 1942, in which there has been set forth for the first time such novel structure and type of medical or surgical dressing.

It is an object of the present invention to provide a flexible carrier in the form of a gauze bandage or adhesive strip, plaster and the like, in combination with a flexible envelope or receptacle sealingly containing therein a liquid or liquidlike substance or any medicament for treatment of wounds.

It is another object of the present invention to provide in combination with a flexible envelope a pad having incorporated therein an ointment or other viscous and wetting substance normally enclosed by said envelope and made up for rapid use by direct application to a wound.

A further object of the present invention is to provide means to open said receptacle or envelope either partly or wholly to make the content thereof directly accessible to wound treatment and immediately prior to its application.

Yet, another.object of the present invention is to provide a dressing or bandage having Incorporated liquid means for direct application to a 3Ro wound of a body part to be treated, said liquid means being so arranged relatively to said bandage or the like that said means are readily applicable to said body part either before, during or after said dressing or bandage has been placed 3.) in position on said body part.

Still a further object of the present invention is to provide a substantially sterile and air-tight receptacle or envelope of flexible material, the latter being impervious to liquid and being adapted to hold liquid or liquid-like substance therein; the envelope is preferably of such character as to be securely held on or within a pad, bandage or any suitable carrier for use in conjunction with wound treatments. Another object of the present invention is to provide tab or extension means forming part of the envelope and adapted to be grasped by a hand of the injured person for facilitating discharge of the liquid-like substance or similar wound treating matter from said envelope onto the wound.

Yet, a further object of the present invention is to provide tab means in crosswise relationship to the length or extension of the bandage, carrier or the like, to which the envelope may be joined, 6a whereby discharge of the content of said envelope may be readily and rapidly effectuated.

Still another object of the present invention is to provide means for sealing a prepared medicinal dressing, preferably in wet-conditlon and in sterile form, within an envelope, and to provide means forming part of said envelope for facilitating tearing off or opening up of said envelope when said dressing is to be applied to the wound.

Yet, another object of the present invention is to provide a method for preparing surgical dressings of the aforesaid type or character, the steps of the method being very simple and resulting in a very economical, inexpensive and very efficient wound or surgical dressing which has unusual properties and does away with the many known disadvantages and inefficiencies inherent in dry and substantially unsterilized dressings having an absorbent pad or filling which has to be specifically prepared before the same can be applied to any wound.

These and other new and useful objects may be attained as will appear from the following disclosure of the invention, which consists in the features of novelty in construction, combination and arrangement of the several parts, hereinafter more fully described and shown In the accompanying drawing illustrating this invention.

In the drawing: Fig. 1 illustrates the surgical dressing or device according to the invention in the stage ofr operation.

Fig. 2 shows a plan view of the dressing wrapped and placed in a package.

ig. 3 shows a top plan view of the dressing.

Fig. 4 shows a top plan view with the protecting cover strips removed.

Fig. 5 is an enlarged cross-sectional view along line 5-5 of Fig. 4. SFig. 6 shows a modified form of a surgical dressing made in accordance with the invention, the protecting cover strips being in the stage of removal.

Fig. 7 shows an enlarged longitudinal sectional view taken along line 7-7 of Fig. 6.

In that form of embodiment of the present invention shown in Figs. 1 to 5, inclusive, of the drawing numeral 15 designates the surgical dressing as applied to a hand 16, the fingers of another hand 18 grasping and. being in the process of pulling tab on extension 1i of the dressing envelope or receptacle 26 to facilitate opening of the latter.

As can be seen from the drawing, the surgical dressing 15, when not in use, is preferably placed and enclosed in a package or wrapper 19 which may be made of waxed or other water-repellent cellulose material 20 sealed around its edges and provided with a pulling strip 21 for facilitating removal of the dressing 15 from said wrapper 19. I Fig. 3 shows a top plan view of the dressing with the conventional protecting gauze cover 23 consisting of parts or strips 23a, 23b which overlap each other at 23c, in this instance, part 23a being positioned on top of part 23b. ( Fg. 4 shows dressing 15 with those protecting cover strips removed thus exposing to view adhesive layer 24 of web or tape 25 and envelope or receptacle 26 hereinafter more fully described.

Envelope 26 is preferably made of a flexible, la substantially water-repellent material, which may be so closed and sealed in any suitable known manner that a medicament in substantially liquid, semi-liquid or viscous form may be encased and preserved in said envelope for a considerable length of time. As a suitable material for the purpose intended may be selected Cellophane, Plioflim or similar waterproof substance, oil silk or the like.

In the embodiment shown in Figs. 4 and 5, a gauze pad 28 containing or prepared with an ointment, salve or other liquid-like medicament is encased in envelope 26 consisting of a relatively strong base wall 30 facing the adhesive layer 24 of tape 25, and of a relatively thin top wall 29 sealed with or otherwise intimately connected to said base wall 30 around its edges 27, said top wall 29 having an extension 32 forming a loop at 31 and overlying the surface of said wall 29 and projecting therebeyond, as clearly seen in Fig. 5. The free end of extension 32 forms a tab 17 provided with an indicator or arrow 17a, said tab being adapted to be turned over tape 25, as illustrated in Fg. 2.

As can be observed from the foregoing explanation, dressing 15 may be easily and most rapidly made ready for use. After removal of wrapper 19 and protecting gauze cover 23 from dressing 15, adhesive tape 25 together with envelope 26 may be applied to a wound, envelope 26 being thereby directly placed upon the wound proper. By pulling tab or similar extension means 17 in the direction of arrow 33 (Fig. 5) and crosswise to tape 25, the loose extension 32 providing a lever for rupturable top wall 29 facilitates ready removal of the latter from base wall 30 at its sealed edges 27 and thus exposing enclosure 28 of opened envelope 26 directly for contact with the wound (Fig. 1).

Figs. 6 and 7 show a modified form embodying ,5 the invention. Tape 40 having the adhesive layer 42 is covered by a single piece of protecting strip 41. Directly underneath strip 41, there is positioned and fixed to a portion of the adhesive layer 42 a pad 43 of gauze or like absorbent material, which in turn overlies an envelope 44, as can be clearly seen in Fig. 7.

Envelope 44 is of a construction substantially similar to that indicated in Fig. 5.. However, top wall 29a and base wall 30a sealed to one another along edge 27a are made of equally strong water-repellent material, said top wall 29a being provided with extension 32a and adjoining tab 17b for the same function, as hereinabove described with reference to Figs. 4 and 5. Envelope 44 preferably holds a medicament 45 in liquid form. It can thus be easily realized that upon manipulation of tab 17b envelope 44 may be opened, so that the liquid or semi-liquid content may penetrate into and through the absorbent 7T material 43 which may contain or may be prepared with another dry or powdered medicament adapted to be dissolved by or reacting with said liquid content, which material 43 is covering and is in contact with the wound under treatment.

It is to be noted that instead of an adhesive plaster or tape any other carriers suitable for wound treatment may be employed, such as bandage, gauze bandage, f. e. battle dressing (Carlisle I model), and the like, the envelope sealingly containing the liquid or semi-liquid medicament being either disposed within the gauze dressing proper or connected thereto in any other way.

It may be further realized that the process of imanufacturing the new style of wound or surgical dressing may be carried into effect in a relatively simple manner.

The envelopes after being prepared and filled with preferably sterilized liquid medicament, an Sointment carrying pad or the like, are sealed and may be intermittently delivered from a station provided with a stack of prepared envelopes crosswise to an adhesive tape continuously fed from a roll of tape, predetermined lengths of said tape carrying one or more envelopes which are pressed against or fixed in any other way to said adhesive tape being then severed from the continuous tape during further steps of the process.

While there has been shown and described and pointed out the fundamental novel features of the invention as applied to the above embodiments, it will be understood that various admissions and substitutions and changes in the form and details of the means illustrated and its operation may be made by those skilled in the art without departing from the spirit of the invention.

Having thus described the Invention what is claimed as new and desired to be secured by Letters Patent, is: 1. A surgical dressing comprising a substantially flexible sealed envelope, a fluid medicament contained in said envelope, an elongated support carrying said envelope and adapted to be placed adjacent a wound, and tab means connected to and overlying said envelope, said tab means extending transversely of said support, whereby upon manipulation of said tab means access of said medicament to said wound may be caused while said support is applied at said wound.

2. A surgical dressing comprising a substantially sealed envelope having a top wall, medicament holding means encased in said envelope, an elongated carrier for supporting said envelope, and tab means connected to said top wall of said envelope and overlying the latter for manipulation to tear off said envelope and to thereby expose said medicament holding means for application to a wound of a body part, said tab means extending transversely of said carrier.

3.
