摘要： A brain injury reduction system provides a protective measure that temporarily or decreases venous drainage out of the intracranial compartment during or immediately before and during a sudden change in acceleration of an individual's head. Specifically, a wearable helmet or other wearable structure of the brain injury reduction system detects an impending collision and determines whether a protective measure is needed. If so, one or more actuation devices provides the protective measure to reduce venous drainage through one or both of the internal jugular veins or paravertebral venous plexus. A first actuation device stimulates a gag reflex or valsalva-like maneuver to reduce venous drainage through the paravertebral venous plexus. A second actuation device can physically compress the internal jugular veins. Thus, the brain injury reduction system minimizes the detrimental impact that may occur due to the sudden change in acceleration of the individual's head.

摘要： A brain injury reduction system provides a protective measure to reduce severity of brain injury caused by collision or blast. A sensing device of the system detects an impending or occurring event (e.g., collision or blast) in an environment surrounding the individual and sends information about the event to a controller of the system. The sensing device can be stationary or moves with the individual. Based on the information, the controller determines whether the event will likely cause brain injury to the individual. If so, the controller sends an instruction to an actuation device of the system to activate the protective measure. The actuation device uses transcutaneous electrodes to electrically simulate glottis closure and contraction of the abdominal musculature to induce a Valsalva-like maneuver. The Valsalva-like maneuver can increases the stiffness of the brain tissues in the intracranial compartment, and thus reduces the susceptibility of the brain tissues to deformation.
