the bandage comprising an outer first layer on the first side of the bandage, an outer second layer on the second side of the bandage, and an inner third layer being disposed between the first and second layers, the bandage further comprising at least one uniter permanently uniting the inner third layer with the outer first layer and permanently uniting the inner third layer with the outer second layer, the inner third layer being permanently united with both the outer first layer and with the outer second layer prior to the bandage being arranged to wrap the at least one wound and the at least one body part whereby the bandage is a unitary member;
the outer first layer comprising an outer side on the first side of the bandage and an inner side adjacent the inner third layer, the outer and inner sides of the outer first layer being separated by a thickness of the outer first layer, the outer first layer comprising a wicking material extending from the outer side to the inner side of the outer first layer, the wicking material of the outer first layer being of a type that does not retain water based-liquids unless saturated and being capable of transporting liquid in contact with the outer side of the outer first layer through the thickness of the outer first layer and to the inner side of the outer first layer;
the outer second layer comprising an outer side on the second side of the bandage and an inner side adjacent the inner third layer, the outer and inner sides of the outer second layer being separated by a thickness of the outer second layer, the outer second layer comprising a wicking material extending from the inner side to the outer side of the outer second layer, the wicking material of the outer second layer being of a type that does not retain water based-liquids unless saturated and being capable of transporting liquid in contact with the inner side of the outer second layer through the thickness of the outer second layer and to the outer side of the outer second layer; and
the inner third layer comprising opposite first and second sides separated by a thickness of the inner third layer, the first side of the inner third layer being adjacent the inner side of the outer first layer and the second side of the inner third layer being adjacent the inner side of the outer second layer, the inner third layer comprising an absorbent material being capable of absorbing water-based liquids and retaining the absorbed liquid until reaching saturation, the absorbent material extending from the first side to the second side of the inner third layer, the absorbent material on the first side of the inner third layer being against the inner side of the outer first layer and the absorbent material on the second side of the inner third layer being against the inner side of the outer second layer, the wicking material of the outer first layer and the wicking material of the outer second layer being a different material than the absorbent material of the inner third layer;
wherein the outer first layer, the outer second layer, and the inner third layer are permanently united to form a single roll;
wherein when the bandage is wrapping the at least one wound and the at least one body part with the outer side of the outer first layer of the bandage in contact with the wound, the outer first layer is configured to transport body exudate away from the at least one wound and from at least one wound site surrounding the at least one wound to the inner third layer, and when the absorbent material in the inner third layer becomes saturated with body exudate, the outer second layer transports body exudate away from the inner third layer to the outer side of the outer second layer;
wherein the bandage extends along a length, the bandage being elastically stretchable along the length of the bandage, wherein the bandage further comprises at least one elastomeric material selected from the group consisting of an olefin-based elastomer, a polyamide-based elastomer, a vinyl-based elastomer, and a mixture thereof;
wherein the wicking material of one or both of the outer first layer and the outer second layer of the bandage comprises at least one of the following materials: a polyamide-based material, a polyurethane material, a polyurethane foam material, a polyester-based material, a synthetic fiber material, and a natural fiber material;
wherein the bandage further comprises at least one healing agent being disposed on one or both of the outside first and second sides of the bandage, wherein the healing agent is an antibacterial or antimicrobial.
2. The bandage of claim 1 , further comprising at least one detectable-signal-generator structured and arranged to generate at least one detectable signal in response to body exudate being in contact with the bandage.
3. The bandage of claim 2 , wherein the at least one detectable signal is detectable by the naked eye.
4. The bandage of claim 3 , wherein the at least one detectable signal comprises at least one color change.
5. The bandage of claim 1 , wherein the inner third layer of the bandage consists solely of absorbent material.
6. The bandage of claim 5 , wherein the absorbent material is at least one selected from the group consisting of cotton, gauze-like materials, alginate materials, polyester materials, hydrocolloid materials, cellulose-based materials, and materials comprising natural or synthetic absorbent polymers or fabrics.
7. The bandage of claim 1 , further comprising a coating on the outer side of the outer first layer of the bandage, the coating capable of resisting adhesion of the bandage to the body part when the outer side of the outer first layer is against the body part.
8. The bandage of claim 7 , wherein the coating comprises a skin-adhesion preventer.
9. The bandage of claim 1 , wherein when the outer side of the outer first layer is in contact with the wound, the wicking material of the outer first layer is configured to transport body exudate away from the wound to the inner third layer of the bandage, and when the absorbent material in the inner third layer becomes saturated with body exudate, the wicking material of the outer second layer transports body exudate away from the inner third layer to the outer side of the outer second layer.
10. The bandage of claim 9 , wherein body exudate transported by the wicking material of the outer second layer to the outer side of the outer second layer is detectable by the naked eye.
11. The bandage of claim 1 , in combination with a pocket attached to or attachable to the bandage.
12. The bandage of claim 11 , wherein one or both of the bandage and the pocket comprises one or more attachment members that releasably attach the pocket to the bandage.
13. The bandage of claim 1 , wherein the bandage comprises torso-wrapability.
14. The bandage of claim 1 , wherein the same type of wicking material is used for both the outer first layer and the outer second layer.
15. The bandage of claim 1 , wherein one or both of the outer first layer and the outer second layer of the bandage consists solely of wicking material.
16. The bandage of claim 1 , wherein the wicking material of the outer first layer is capable of transporting perspiration in contact with the outer side of the first outer layer.
17. The bandage of claim 1 , wherein when the bandage is elastically stretched from a relaxed state to generate a force urging the bandage back to the relaxed state, and the stretched bandage is placed against a body part having a suture, the force compresses the suture.
18. The bandage of claim 1 , wherein the wicking material of the outer first layer is configured to generate unidirectional flow of exudate towards the inner third layer when the outer first layer is transporting exudate away from the at least one wound.
19. The bandage of claim 1 , wherein the wicking material of the outer second layer generates unidirectional flow of exudate towards the outer side of the outer second layer when the outer second layer is transporting exudate away from the inner third layer.
20. The bandage of claim 1 , configured for being wrapped about the body part and being disposed in a wrapping arrangement, at least one fastener attached to the bandage and resisting unwrapping of the bandage, each at least one fastener being selected from the following: a hook and loop fastener, a clip, a clasp, an adhesive tape, and a pin.
21. The bandage of claim 1 , wherein the bandage is washable and reusable.
