发明名称 Fluidized positioning and protection system
摘要 The present invention provides a fluidized positioning system including an inner bladder formed of a medium that has no memory or substantially no memory. An outer bladder is placed adjacent to or coupled to the inner bladder. The outer bladder is partially filled with a composition. The composition can be beads, such as polystyrene beads, or beads made of a similar medium. A valve extending from the outer bladder permits the evacuation of all or some of the air from the outer bladder which causes the outer bladder to be reduced in size due to loss of air between the beads and adjusts the rigidity of the outer bladder to allow the outer bladder to form fit the inner bladder around whatever body extremity it is being used on.
