Vacuum splint, also named vacuum transport stretcher, is an emergency immobilization device like a small vacuum mattress that is used in emergency immobilization as a temporary splint. Vacuum splints operate by extracting air from the splint itself to enable the thousands of polystyrene balls inside the splint to mold around the injured body part similar to an orthopedic cast. Vacuum splints are primarily used by paramedics to splint trauma-related injuries, joint dislocation, subluxation, and extremity fractures. The main function of the vacuum splint is supplying immobilization and short distance patient transporting. The material is TPU. TPU vacuum splint advantages are durable, soft and strong. The vacuum splint advantages include the ability to provide support whilst relieving pressure at the injury site. Vacuum splints are compatible with X-Ray, CT and MRI.
