A spinal immobilizer extrication vest designed to be compact and easily applied to accident victims in confined spaces, such as deformed structures of automobiles, or applied following structure collapse. The device is constructed of lightweight nylon material, with rigid longitudinal cylindrical rods which, in addition to intrinsic rigidity form a stiffening arc when the rods are applied about the victim and secured anteriorly, by two overlapping nylon body panels with hook fastener and loop fastener material. Contiguous ear panels augment head immobilization, provided by prior application of a rigid cervical collar. Following placement of such a collar, the vest is positioned, body panels are opened beneath the victim's arms and wrapped around the victim providing cervical, thoracic and lumbar immobilization. Sacral and pelvic support is provided by a triangular cradle of nylon material which extends from the lower edge of the central body panel. The pelvic cradle is positioned under the sacrum by passage behind either leg of a single strap, extending from the apex of the triangular cradle. Pulling the strap inferiorly advances the pelvic cradle under the sacrum and buttocks. The strap is then pulled superiorly through the crotch to fasten anteriorly by hook fastener and loop fastener material to the outside of the secured, overlapping body panels. Seven lifting straps are located to facilitate controlled movement of the immobilized victim.
