` SWW/wrom' AARoN WEBB ROBERTS Patented Nov. 29, 1949 UNITED STATES y PATENT OFFICE 2,489,675 A BANDAGE Aaron Webb Roberts, Dallas, Tex.
Application June 18, 1947, Serial No. 755,343 s claims. (o1. 12s-156) This invention relates to new and useful improvements in bandages and more particularly to medicated bandages.
One object of the invention is to provide an improved bandage having an ointment or medicament sealed therein so as to be maintained in a sterile condition for immediate application when needed.
Another object of the invention is to provide an improved bandage having a. sealed container of liquid ointment or medicament which is adapt-- ed to be ruptured or fractured immediately prior to application ofthe bandage.
A further object of the invention is to provide an improved bandage, of the character described, wherein an absorbent pad is associated with the containerV for receiving the ointment or medicament therefrom, the pad having meansy for coniining and preventing the escape of said ointment or medicament.
An important object of the invention is to provide an improved bandage, of the character described, wherein the container is formed of suitablefriable or frangible material so as to .be readily fractured or punctured when it is desired to apply the bandage.
vA particular object of the invention is to provide an improved bandage, of the character described, wherein the container has a weakened portion to facilitate rupturing or fracturing of e the same.
Still another object of the invention is to provide an. improved bandage, ofv the` character described, wherein a plurality of containers. are associated with a large, pad of absorbent material, whereby bandages of different sizes, having one ormore4 containers, may be. cut. from the pad when desi-red.
A construction designed to carry out the invention will be hereinafter described together with other features. of the invention.
The invention will bev more readily understood from. a reading of the following speciiication and by reference to the accompanying drawing, wherein examples of the invention are shown, and wherein AFig. 1 is an isometric viewl of a bandage, constructed in accordance with. the invention,
Fig, 2 is a transverse, sectional View of a medicament-lilled container forming a part. of thev bandage,
.,F'ig. 3 isv atransverse sectional. view of4 the bandage,
Figs. 4 and 5 are views,u similar teilig. 3, show-- modified forms of; bandages.
Fig.'6 is a isometric view of a portion of a large' bandage4 having a plurality of containers incorporated therein, and
Fig.' '7 isa side elevational view illustrating'` one method .of forming the containers.
'.In the drawing, the numeral I0 designatesia bandage which includes a sheet or tape Il of suitable adhesive material, a pad I2 of absorbentv material and a liquid or paste container i3. 4Thief adhesive surface of the Sheet Il. is directed toward the padl l2 and container i3 and is protected by overlying strips or sheets i4 of gauze:` or other porous fabric in the customary manner.- The bandage, composed of the foregoing elements may be enclosed within a conventional envelope (not shownl in the usual mannervso as tov rbe maintained in a sterile condition. Of course,Y any number of bandages may be pack--Y aged together to facilitate distribution and hani dling of the same..
The. sheet Il may be formed of any suitable adhesive material or fabricY having an adhesive coating or surface, such as adhesive tape or plas'- ter or cellulose tape. The latter is desirable due' to its imperviousness t'o liquid, but substantially the same results may be obtained with other ade hesive materials which have been treatedv or im-- pregnated with va liquid-resistant material so as to'providev a protective coating or backing. Al` though the pad I2: is preferably formed offelt, it isfmaniiest that several layers of gauze or other. suitable soft, absorbent material could be enr-'- ployed.
Both-the pad and the. container I3 have been illustrated as substantially square but may be of any desired shape. The container is prefer-- ably iormed of a suitable frangble or friable material, such as thin glass, plastic, gelatin .or other suitable. material', and is hollow for re ceiving a medicament or ointment l5 .which-Gis` preferably'in liquid form and which may vary from a'relatively' thin to a relatively thick condition. Prior to application of the bandage l0, the container is adapted to be fractured or ruptured in any suitable manner so as to permitthey escape of liquid therefrom, which liquid partially permeates `or saturates the pad l2 Ato provide a wet or moist dressing for burns, cuts, wounds` and other abrasicns of the skin. If desired, the container may be providedv with a small projec tion or tit i6 which is adaptedv to be separated from the body of the container to permit the escapeoi liquid therefrom. To facilitateseparation or severing of' the tt- I6,the wall thereof may bevi-weakened orfreduced in thickness asj shown by the numeral I1. It is pointed out, however, that the container may be ruptured, fractured, or punctured irrespective of whether the same is provided with a tit or weakened portion.
In Figs. 1 and 3, the container is shown interposed between the sheet II and the pad I2. A recess I8 is formed in the underside of the pad for receiving the container and said pad is necessarily of greater size or area than said container. The tit I6 projects upwardly through an opening I9 formed centrally in the upper surface of the pad.
A modified form of bandage, 20, is shown in Fig. 4 and includes an adhesive sheet or tape 2I, an absorbent pad 22 and a sealed liquid container 23. These elements are of the same general construction as the sheet II, pad I2 and container I3 of the first form of the invention, and the protective gauze strips have been omitted for the purposes of illustration. The pad 22 and container 23 are of the same relative size, but said pad is interposed between said container and the adhesive sheet 2 I. Since the container is not provided with a tit or weakened portion, the same is adapted to be fractured or punctured in any suitable manner so as to permit the escape of liquid therefrom; however, this container may be provided with a depending projection extending into the pad and adapted to be severed or otherwise fractured. Prior to application of this form of bandage, it is preferable to remove the container.
As shown in Fig. 5, the absorbent pad need not be recessed for receiving the liquid container. This bandage 24 includes a similar adhesive sheet or tape 25, pad 26 and container 2T. The pad overlies the container which is interposed between said pad and the adhesive sheet and which may be of the same size as the pad. A small projection or tit 28 may be formed on the upper surface of the container so as to project upwardly through an opening 29 formed in the pad. In addition, the tit 28 may be weakened as shown by the numeral 30 to facilitate separation or severing of the same from the body of the container.
. In order to prevent loss of the liquid, which is adapted to maintain the pad in the moist condition, a coating or backing 3l may be interposed between the adhesive sheet and the container (Fig. or between the pad and said sheet when the construction shown in Fig. 4 is used. The backing or coating may be in any suitable form so` long as it is liquid-resistant or impervious to oil, water or other moisture. It is preferable that this backing be of greater size than the pad and container so as to project beyond the margins thereof, but is of less length than the adhesive sheet so as not to interfere with the securing properties of the latter. When a backing or coating of this nature is employed, it is unnecessary that the adhesive tape be of liquid resistant material in order to prevent escape or loss of the liquid. By securing the backing or coating to the back or outer surface of the adhesive sheet, the same may be co-extensive with said sheet.
As shown in Fig. 6, the bandages may be made invlarge sheets instead of in strip form. This form of bandage 32 includes a large sheet of adhesive material 33, a large absorbent pad 34, of rectangular or other shape, and a plurality of liquid containers 35. The latter have been illustrlalted as being of the same general construction as the containers I3 and 21, but may be similar to the containers 23. Small bandages, having one or more containers, may be obtained from the bandage 32 by merely cutting the sheet 32 and pad 34 between any of the containers 35 or, if desired, the entire bandage may be employed.
If desired, the containers may be formed in a continuous strip as shown in Fig. '7. The container material may be in the nature of an elon gated, flat tube or envelope 36 into which the liquid is introduced. Individual containers 31 are provided by drawing or pressing the envelope together at spaced intervals to provide connecting portions or necks 38. Any of the containers may be formed in this or any other suitable manner. Manifestly, the neck portion 38 may be severed to provide individual containers.
From the foregoing, it will be readily apparent that an improved bandage has been provided. A liquid ointment or medicament may be maintained in a sterile condition for instantaneous use, which ointment or medicament is released whenever desired by merely fracturing or puncturing the container. Due to the association of the absorbent pad in close proximity to the container, said pad is saturated and maintained in a moist condition by the liquid escaping from the container for a prolonged period of time. In addition to the sterility of the bandage, the same is in convenient form for packaging and is readily available for use whenever desired.
The foregoing description of the invention is explanatory thereof and various changes in the size, shape and materials, as well as in the details of the illustrated construction may be made, within the scope of the appended claims, without departing from the spirit of the invention.
What I claim and desire to secure by Letters Patent is:
l. A bandage including, a liquid container of frangible material, a pad of absorbent material, the container and pad being disposed in overlying relation to each other, liquid resistant means overlying said container and pad for preventing loss of the liquid upon rupturing of said container, and a sheet of adhesive material disposed in overlying and overlapping relation to said container and pad and means, the pad having an opening therein, the container having a tit extending through the opening to facilitate rupturing of said container.
2.
