A bandage is a strip or roll of gauze or other material for wrapping or binding any part of the body.

Bandages may be used to stop the flow of blood, absorb drainage, cushion the injured area, provide a safeguard against contamination, hold a medicated dressing in place, hold a splint in position, or otherwise immobilize an injured part of the body to prevent further injury and to facilitate healing.

Roller bandage a tightly rolled, circular bandage of varying widths and materials, often prepared commercially. In an emergency, strips may be torn from a sheet or piece of yard goods and rolled. When more than a few inches of length is needed, rolling is essential for quick and clean bandaging.

The bandage should not be made so tight that it interferes with circulation.
