Bandage Frame

In a co-pending, co-owned application invented by Frederic Grossmann and Larry A. Sims, filed Sept. 11, 1980, Ser. No. 186,352, now U.S. Pat. No. 4,374,520, clamp on and other type of handles are described for use in applying large area adhesive backed bandages to patients. Such bandages when applied to a patient require extremely careful handling, as shown in U.S. Pat. No. 3,236,370, to prevent the bandage from sticking from itself or excessively wrinkling. When used as an "incise" drape, a surgical incision is made directly through the bandage and into the patient.

The problem of handling large area bandages, such as for burn dressings, wound dressings, and incise drapes, is overcome by the present invention which includes a frame structure for spreading the highly flexible adhesive backed bandage into a somewhat flattened configuration during the application of such bandage to a patient. After the bandage has been applied, the frame structure is removed from the bandage, permitting the bandage to have full flexible freedom to move with the patient's body.

FIG. 1 is a top plan view of the frame attached to the adhesive backed bandage;

FIG. 2 is a top plan view of the frame prior to attaching to such bandage;

FIG. 3 is an enlarged sectional view taken along line 3--3 showing a first embodiment of the frame in relatively thin configuration;

FIG. 4 is a sectional view similar to FIG. 3, but showing a second embodiment of the frame construction of a thicker configuration;

FIG. 5 is an enlarged sectional view taken along line 5--5 of FIG. 1;

FIG. 6 is a side elevational view showing the frame being peeled from the bandage after application to a patient;

FIG. 7 is a top plan view of a sterile package broken away to show a package frame and bandage system; and

FIG. 8 is a sterile containing a frame only.

In FIG. 1, an adhesive backed flexible bandage, shown generally at 1, is secured to a frame 2. For easy attachment and detachment of the frame, a protruding border 3 of the flexible drape is provided. The frame unattached to flexible bandage 1 is shown in FIG. 2.

In a first embodiment of the frame shown in the sectional view of FIG. 3, a frame back 5 is coated with an adhesive 6, which in turn is protected by a peel off liner 7. In this figure, the frame back 5 is of relatively thin material, such as a heavy paper. Thermoplastic or other material could also be used for the frame back. FIG. 4 shows a second embodiment of the frame wherein a frame back 9 is of a relatively thicker material, but not as wide as the FIG. 3 embodiment.

When the frame 2 is attached by its adhesives to the top of flexible bandage 1, the configuration is that of the sectional view of FIG. 5. Bandage 1 preferably has a backing 10 that is coated with an adhesive 11. A strip member 12 secured to adhesive 11 prevents the removable liner 13 from sticking to an edge portion of the flexible bandage. This provides an easily graspable tab on liner 13 that is unstuck to the adhesive when peeling off the liner 13. Liner 13 can be of a discardable paper material. The flexible backing 10 and adhesive 11 are preferably of a water vapor permeable, liquid water and bacteria impermeable film material. One type of such water vapor permeable bandage is manufactured by the British firm of Smith & Nephew and marketed in the United States under the trademark OP-SITE. An instruction sheet for such OP-SITE bandage is attached showing how it is applied to a patient without the benefit of the present invention.

When the frame 2 and flexible bandage 1 are attached to each other and liner 13 has been removed, the bandage is smoothed down against the contours of a patient's anatomy. Preferably, the frame 2 is slightly flexible or bendable so as to temporarily conform to a patient's anatomy during application of the flexible bandage. After such application, the frame can be peeled off of the flexible bandage 1, as shown in FIG. 6. Thus, after application, the bandage resumes its very highly flexible nature so as to readily move with the patient's body. Even though, as shown in FIG. 6, the frame is slightly flexible or bendable, it still remains stiffer than the flexible bandage material itself.

The system, which includes the frame 2 and flexible bandage 1, are contained within a sterile package, as shown in FIG. 7. The package of FIG. 7 has been broken away to reveal the frame and bandage. In FIG. 7, the frame can be preattached to the bandage, or alternatively, they can be attached to each other upon opening the package of FIG. 7. FIG. 8 shows a sterile package in which only the frame is within the package.

Throughout the specification and claims, the term "bandage" has been used in a very broad sense to include any large area adhesive backed sheet material applied to a patient, such as a wound dressing, burn dressing, incise drape, etc. The term "frame" has also been used in a broad sense to include an attachable structure which is applied to the drape for spreading into a more manageable configuration during the application to the patient. Such frame need not enclose a central opening nor be rectangular in shape.

In the foregoing description, specific examples have been used to describe the invention. However, it is understood by those skilled in the art that certain modifications can be made to these examples without departing from the spirit and scope of the invention.
