Gauze and bandages are some of the earliest forms of medical equipment, designed to keep a wound clean and protected from outside contaminates while healing. Early civilizations utilized cotton dressings often paired with natural healing remedies that promoted a clean environment in the wound and accelerated recovery. As technology advanced, synthetic fibers were introduced alongside organic ones, and advanced medicated ointments could be mixed into the fabric itself, further advancing on the simple technology. In this modern era, it only makes sense that the technology would continue to evolve with society.
This evolution has culminated in the modern advents of Enhanced Bandaging and Gauze, sometimes referred to as "Nanobandages", due to the materials often incorporating beneficial nanostructures, with more expensive models even including simple nanotechnology. The basic ideas of medicated bandages and gauze was improved upon with advancements in material composites and the formulation of highly-efficient and potent formulas capable of both providing an antiseptic solution as well as introducing healing agents which speed the recovery time for wounds that are dressed in such equipment.
Added properties to the material utilizing knowledge of nanomaterials and the latest of synthetic and lab-grown organic fibers allow for even the fabric of the dressing to further aid in the healing process of the wound, expensive supplies even integrating basic nanotechnology which is capable of sealing abrasions and lacerations at an accelerated rate, usually around 1.5x the speed of recovery that would be found with using basic supplies, though at the risk of EMPs leading to their ineffectiveness. When used as compression for hyper-extended joints and pulled muscles, a full recovery has been noted to occur within 24 hours of application, given proper rest is allowed so as to not further exacerbate said injuries.
While these technological marvels may seem to be miraculous, they are only designed for application on minor to moderate injuries, such as small burns of 1st and 2nd degree, lacerations, abrasions of the dermis, and contusions. For more serious injuries, it is extremely recommended that you seek out the help of a trained professional, or use a certified autodoc.
