According to CNN a new device, designed to prevent traumatic brain injuries (TBIs), has been approved by the US Food and Drug Administration (FDA). The FDA declared that the Q-Collar was authorized for athletes 13 and older and that it can be used during football, soccer and other high-impact sports.
The device is a c-shaped collar that is designed to be worn at the base of the neck. The collar clamps down on blood vessels in the neck, increasing the amount of blood volume in the skull. This increase of blood volume limits how much the brain can move inside the skull.
