BACKGROUND

There has been a substantial problem in applying large area adhesive backed bandages to patients. Such bandages might be used for a surgical drape, such as shown in Patent 3,236,370. There is considerable difficulty in keeping the large area drapes from sticking to themselves or from wrinkling during the application procedure. Often several nurses or physicians are required to apply such surgical incise drapes. The drape is called an "incise" drape when a surgical incision is made directly through the drape. Similar problems exist with other relatively large area bandages for wounds or burns.

One type of adhesive backed bandage having a relatively large area making it difficult to handle is a vapor permeable, bacteria impermeable transparent bandage manufactured by the British firm of Smith &. Nephew, Ltd. and marketed in the United States under the OP-SITE trademark. This OP-SITE bandage has had considerable problems because of its extremely flexible nature and tacky adhesive that tends to stick to itself and wrinkle if not very carefully handled when applied to a patient.

SUMMARY OF THE INVENTION

The present invention overcomes the above problems by providing an applicator handle that is joined to the bandage while such bandage is being applied to the patient, and this applicator handle is removed after the bandage has been applied so the bandage can be smoothly contoured to the patient's anatomy. Such applicator handle can be mechanically or adhesively secured to the bandage.

DETAILED DESCRIPTION

In Figures 1 and 3, a large area bandage, shown generally at 1, is illustrated. This bandage includes a backing 2 that has one surface coated with an adhesive 3. A nonadhesive strip 4 covers an outer edge portion of the adhesive 3 to prevent such outer edge portion from sticking to a removable liner 5, which protects the adhesive 3 until ready to use. Strip member 4 thus provides a tab section for grasping and pulling off the liner 5. Backing 2 and strip member 4 can be of a thermoplastic material, while removable liner 5 can be of a paper material. For use as a bandage, preferably the backing 2 and adhesive 3 are highly permeable to water vapor, but impermeable to liquid water and bacteria passage. Thus, a patient's covered wound, or body areas adjacent such wound, can breathe and receive oxygen through the bandage.

Figure 2 shows the flexible bandage with the protective liner 5 removed.

As shown in Figures 2 and 4, a rigid handle, shown generally at 7, is clamped along a left edge of the flexible bandage of Figure 2. Also, a rigid handle 8 is clamped to the right edge portion of the flexible bandage in Figure 2. This rigid handle, shown in Figures 5 and 6, can include a pair of opposed jaws 9 and 10 that are connected by a hinge portion 11. Jaws 9 and 10 can be held in clamped position by a snap latch 12. Between jaws 9 and 10 in Figure 5 is clamped the flexible bandage, shown generally at 1.

It is acknowledged that hinged type rigid clamps with snap latches have been known and used for completely different purposes. For instance, such clamps have been used to hold upper edges of paper sheets for writing, clamp umbilical cords while they are being cut, etc. To applicants' knowledge, such a hinged clamp has never been used in a system which includes clamping an adhesive backed bandage during the application of such bandage to a patient and thereafter removal of such clamp, so as not to interfere with the flexible functioning of the bandage.

WIPO

One example of the large area bandage is shown in Figure 7 where an incise drape 15 has been secured to a patient 16. A surgical incision 17 has been made through both the drape and the patient. The water vapor permeable and liquid and bacteria impermeable incise drape protects the patient from contamination adjacent the surgical wound.

In a second embodiment of the applicator handle shown in Figures 8 and 9, a rigid rectangular handle 19 is attached along one edge of a flexible bandage 20. A similar applicator handle 21 is attached to an opposite edge. It should be noted that in Figure 8 the applicator handles are along the longer edges of a rectangular bandage, whereas in Figure 2 the handles are along the shorter edges of a rectangular bandage. The applicator handles could be placed in either of these locations. In the enlarged sectional view of Figure 9, the rectangular tubular handle 19 has an adhesive coating 23 on one surface that is temporarily protected by a removable liner 24. In Figure 8, this liner 24 has been removed and the adhesive 23 has been secured to flexible drape 20.

When the adhesive backed flexible drape is applied to a patient, a patient's anatomy often has various curved configurations. As shown in Figure 10, the flexible bandage with a backing 25 and adhesive 26 has been attached to a patient, shown schematically in section at 27. Strip members 28 and 29 prevent the outermost edges of the bandage from adhering to the patient, thus making convenient tabs for grasping when removing the bandage from the patient. After the bandage has been applied to the patient, the rectangular tubular handles 19 and 21 are peeled from the back of the flexible bandage. This can be done by a rotating action.

Figure 11 shows still another embodiment in which the flexible bandage 31 is secured to opposed applicator handles 32 and 33, which are shown with flattened lower edges secured to bandage 31 by adhesive. The applicator handles of Figure Jl are formed of extruded tubing which can be somewhat flexible or bendable (although stiffer than the flexible bandage). Thus, as in Figure 12, when the flexible bandage is applied to a patient, handles 32 and 33 can temporarily conform to the patient's anatomy when sticking down the bandage. Handles 32 and 33 would be removed from such flexible bandage after the application step so as not to interfere with the flexible functioning of the bandage 31.

The flexible bandage and applicator handles can be packaged together in a sterile package such as 35 in Figure 13. Here flexible bandage 36 is packaged with applicator handles 37 and 38. These handles 37 and 38 can be either preattached to the flexible drape 36 or merely contained in the same package for connection to such bandage at the time of application to a patient. Alternatively, a sterile package 39 could contain one or more applicator handles, such as 40, for subsequent combining with a separate bandage.

Throughout the specification and claims the term "bandage" has been used in a broad sense to include various types of dressings and drapes which are adhesivdy applied to a patient.

In the above 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.
