Abstract
A vacuum immobilizer support is disclosed which includes an elongated, flexible casing having neck, thoracic and pelvic regions. An evacuation valve is provided to allow the casing to be converted from a flexible state to an evacuated state. Stiffener sections are provided in the casing to prevent transverse bending of the casing in the neck, thoracic and pelvic regions. The stiffener sections allow transverse bending along an axis between the thoracic and pelvic regions. An intermediate stiffener section is provided to prevent longitudinal shortening of the casing between upper and lower stiffener sections. Discrete elements are disposed within the casing and allow the casing to conform to a patient when in its flexible state and to be rigidly fixed when in its evacuated state.
