Abstract: Human stabilization platforms may include a support structure configured to rigidly support a person. A rail may extend longitudinally from proximate a portion of the support structure configured to receive the person's head thereon to proximate a portion of the support structure configured to receive the person's lower legs thereon on each lateral side of the support structure. Each rail may include selectable attachment structures distributed along at least a portion of the longitudinal length of the rail. The selectable attachment structures may be configured to receive modular accessories to be secured to the human stabilization platform. The selectable attachment structures may include a channel including alternating enlarged sections and constricted sections.

Abstract: A liner system, including a plurality of arcuate panels vertically interlocked, each arcuate panel comprising fiber reinforced composite. Each arcuate panel includes a first engagement tab disposed at a first edge of a panel frame, a second engagement tab disposed at a second edge of the panel frame, the second edge arranged opposite the first edge, a third engagement tab disposed on a third edge of the panel frame, and a fourth engagement tab disposed on a fourth edge of the panel frame, the fourth edge arranged opposite the third edge.

Each rail may include selectable attachment structures distributed along at least a portion of the longitudinal length of the rail. The selectable attachment structures may be configured to receive modular accessories to be secured to the human stabilization platform. A handle may be located at each end of each rail, each handle being rotatable with respect to the rail. Each handle may be configured to enable manual handling and transport of the human stabilization platform.

Abstract: Head-and-neck immobilization devices may include a yoke sized and shaped to contact a person's back and shoulders. Two head immobilization pads may be sized and shaped to respectively contact opposing sides of the person's head, each of the two head immobilization pads connected to the yoke at a single location by a respective selectively rotatable, selectively fixable connection and independently fixed in place to immobilize the person's head responsive to the rotatable, selectively fixable connection to the yoke in a fixed mode.

Abstract: Head-and-neck immobilization devices may include a yoke sized and shaped to contact a person's back and shoulders. Straps may extend from the yoke, the straps configured to secure the yoke to the person's torso. Two head immobilization pads may be sized and shaped to respectively contact opposing sides of the person's head, each of the two head immobilization pads connected to the yoke by a respective selectively rotatable, selectively rigid connection. A majority of the person's head may remain unobstructed by the head-and-neck immobilization device when the two head immobilization pads contact the two opposing sides of the person's head and are rigidly secured in place to immobilize the person's neck and head.
