Description:

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 adapted to be ruptured or fractured immediately prior to application of the 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 container for receiving the ointment or medicament therefrom, the pad having means for confining 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 suitable friable or frangible material so as to be readily fractured or punctured when it is desired to apply the bandage.

A 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 the same.

Still another object of the invention is to provide an improved bandage, of the character described, wherein a plurality of containers are associated with a large pad of absorbent material, whereby bandages of different sizes, having one or more containers, may be cut from the pad when desired.

A construction designed to carry out the invention will be hereinafter described together with other features of the invention, The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawing, wherein examples of the invention are shown, and wherein: Fig. 1 is an isometric view of a bandage, constructed in accordance with the invention, Fig. 2 is a transverse, sectional view of a medicament-filled container forming a part of the bandage, Fig. 3 is a transverse, sectional view of the bandage, Figs. 4 and 5 are views, similar toFig. 3, showjn modified forms, of bandages, Fig. 6 is a isometric view of a portion of a large bandage having a plurality of containers incorporated therein, and Fig. 7 is a side elevational view illustrating one method of forming the containers.

In the drawing, the numeral 10 designates:a bandage which includes a sheet or tape I I of suitable adhesive material, a pad 12 of absorbent material and a liquid or paste container 13. The adhesive surface of the sheet II is directed toward the pad 12 and container 13 and is protected by overlying strips or sheets 14 of gauze. or other porous fabric in the customary manner.

The bandage, composed of the foregoing elements may be enclosed within a conventional en-. velope (not shownY in the usual manner so as to be maintained in a sterile condition. Of course, any number of bandages may be packaged together to facilitate distribution and handling of the same.

The sheet I may be formed of any suitable adhesive material or fabric having an adhesive coating or surface, such as adhesive tape or plaster or cellulose tape. The latter is desirable due to its imperviousness to liquid, but substantially the same results may be obtained with other adhesive materials which have been treated or impregnated with a liquid-resistant material so as to provide a protective coating or backing. Although the pad 12: is preferably formed of felt, it is manifest that several layers of gauze or other. suitable soft, absorbent material could be employed.

Both the pad and the container 13 have been illustrated as substantially square but may be of any desired shape. The container is preferably formed of a suitable frangible or friable. material, such as thin glass, plastic, gelatin or other suitable material, and is hollow for receiving a medicament or ointment 15 which is preferably in liquid form and which may vary from a relatively thin to a relatively thick condition. Prior to application of the bandage 10, the container is adapted to be fractured or ruptured in any suitable manner so as to permit the escape of liquid therefrom, which liquid partially permeates or saturates the pad 12 to provide a "wet" or moist dressing for burns, cuts, woundsi and other abrasions of the skin. If desired, the container may be provided with a small projection or tit 16 which is adapted to be separated from the body of the container to permit the escape of liquid therefrom. To facilitate separation or severing of the tit 16, the wall thereof may be .weakened or reduced in thickness as shown by the numeral IT. 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 12. A recess 18 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 16 projects upwardly through an opening 19 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 21, an absorbent pad 22 and a sealed liquid container 23. These elements are of the same general construction as the sheet II, pad 12 and container 13 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 21. 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 27. 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 31 may be interposed between the adhesive sheet and the container (Fig. 5) 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 in large 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 illustrated as being of the same general construction as the containers 13 and 27, 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 elongated, flat tube or envelope 36 into which the liquid is introduced. Individual containers 37 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: 1.
