ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to bandages, and more specifically, to a transparent, self-adhering, span-over-the-wound bandage having a blister pack design to enclose a wound within a transparent, sterile, substantially hemispheric, protective bandage wherein only a peripheral base area having adhesive properties makes contact with the skin thereby eliminating the stretching and squeezing of the peripheral area of the wound that is common with conventional bandages. The present invention provides for constant monitoring of the injury from all angles without having to undress, redress, and stress the affected area. For aesthetic purposes the transparent span-over-the-wound bandage can come with decorative pieces of gummy paper to be placed over the bandage when visual inspection of the wound is not desired and can be easily removed as needed. The suspended nature of the bandage provides a sterile environment to promote the healing process and prevents pressure on the wound from contact that can irritate the injury caused by clothing, inadvertent touching, scratching, etc. The transparent span-over-the-wound bandage is manufactured of a non-penneable material that when properly applied forms a hermetically sealed containment chamber to protect the injury from airborne contaminants and water. The present invention is easier to apply than conventional bandages because the semi-rigid, hemispheric structure has no flapping ends that can roll up and stick together when tile adhesive backing is peeled off. The peel-off, adhesive backing also maintains the sterility of the bandage's inner surface by spanning across the open base area and all the peripheral contact edges until ready for use. The present invention could also have a two-piece configuration in which a blister pack canopy can be replaceably removed from an adhesive base to provide access to the wound in order to apply ointment or medicine without disturbing the injury or the adhesion of the base portion to the epidermal tissue. The transparent span over-the-wound bandage can come in a plurality of sizes and configurations including having a venting means to allow to flow through the bandage's interior. Furthermore, the present invention could be used as a protective covering for other items and uses such as restricting access to buttons on control panels or light switches et al. Two transparent span-over-the-wound bandages could also be affixed to one another's adhesive base to form a sealed disposable container to carry items such as pills or stool samples.
2. Description of the Prior Art
There are numerous bandages that provide for the protection of epidennal injuries. While these bandages may be suitable for the purposes for which they were designed, they would not be as suitable for the purposes of the present invention as heretofore described. It is thus desirable to provide a bandage having a transparent, self-adhesive blister pack style protective covering that has a non-penneable surface, a sterile interior surface and a peel off adhesive base. It is further desirable to provide a transparent, span-over-the-wound bandage that can be detachably fastened to a peel off self-adhesive base to allow for the application of a medicine or ointment and treatment of the affected area without disturbing the injury or the adhesion of the base to the skin.
SUMMARY OF THE PRESENT INVENTION
The present invention relates generally to bandages and, more specifically, to a transparent span-over-the wound bandage having a blister pack design wherein only the wider peripheral edges of the base area contact the surface to which the bandage is being applied while a narrower central portion remains elevated above the area to be protected.
A primary object of the present invention is to provide a transparent span-over-the wound bandage that will overcome the shortcomings of prior art devices.
Another object of the present invention is to provide transparent span-over-the wound bandages that are safe to use by providing a hermetically sealed, hygienic environment to promote the healing of a wound by protecting it from airborne contagions, water, and pressure from external sources
Another object of the present invention is to provide transparent span-over-the-wound bandages that are fabricated of a non-permeable, malleable material that conforms to the surface being applied thereon wherein all peripheral edges of the bandage have an adhesive base to maintain the bandage to the aforementioned surface thereby forming a hermetically sealed chamber to contain the object to be protected.
A still further object of the present invention is to provide transparent span-over-the wound bandages that are easy to use because the semi-rigid qualities of the substantially dome-like form of the bandage make it easy to hold securely while peeling off the adhesive backing that covers the entire open base area including the adherent peripheral edges.
Still another object of the present invention is to provide a transparent span-over-the-wound bandage wherein the transparency of the bandage allows for accurate placement over the wound and the semi-rigid adhesive base applies pressure uniformly and simultaneously to the epidennal tissue surrounding the wound thereby preventing the stretching and squeezing and subsequent further traumatization of the injury that is common with conventional bandages.
A yet further object of the present invention is to provide transparent span-over-the wound bandages that have a sterile interior containment area which is maintained until ready to use by the adhesive backing that covers the entire open base area including the adherent peripheral edges.
Another object of the present invention is to provide transparent span-over-the wound bandages that allow for visual inspection of the wound or protected object while the bandage is in place.
Yet another object of the present invention is to provide transparent span-over-the wound bandages that have decorative pieces of gwmny paper to stick onto the exterior surface of the bandage to obstruct the view of the injury when visual contact is not desired.
Still another object of the present invention is to provide a transparent span-over-the-wound bandage having a venting means to allow fresh air to circulate through the bandage to promote the healing of the wound.
Another object of the present invention is to provide a transparent over-the-wound bandage having a venting means utilizing a filtration system to allow fresh air to circulate through the bandage while inhibiting the entrance of airborne particles therein.
Yet still another object of the present invention is to provide transparent span-over-the wound bandages that are comprised of an adhesive base section which mates with a replaceably detachable blister pack canopy to permit access to the injury without disturbing the integrity of the adhesive seal to the skin.
A yet further object of the present invention is to provide transparent span-over-the wound bandages wherein two bandages could be fastened together, adherent base to adherent base, to form an airtight container to carry items such as pills or stool samples.
A still further object of the present invention is to provide transparent span-over-the wound bandages that can be used to limit access to items such as control buttons or light switches.
Another object of the present invention is to provide transparent span-over-the wound bandages that can be of various sizes and configurations.
Additional objects of the present invention will appear as the description proceeds.
To the accomplishment of the above and related objects, this invention may be embodied in the form illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only, and that changes may be made in the specific construction illustrated and described within the scope of the appended claims.
