Abstract: A device for treating wounds on an individual is disclosed. The device includes a flexible foam, a treatment suitable for treating the wound placed in relative proximity to the foam, and a flexible fabric with recoverable properties substantially circumferencing the wound and the treated foam. The flexible fabric maintains the treated foam in substantial proximity to the wound to allow the treatment to treat the wound. A bandage suitable for treating wounds on an exterior limb is disclosed. The bandage includes a butterfly shaped flexible fabric, at least one Hook and loop material type fastener attachment located on the edge of the butterfly shaped flexible fabric, at least two foam layers located axially in the center of the butterfly shaped flexible fabric, and a medication suitable for treating the wound proximately located with respect to at least a first of the at least two foam layers.
