Abstract

Abstract A collapsible cervical cervical immobilization device comprising two pieces of treated fiberboard. The pieces are placed one on top of the other and joined together at the center of each. The upper member consisting of different sections formed by and attached to each often by fold lines. The fold lines allow these sections to be rotated independent of each other with the fold lines acting as a hinge. When certain sections are folded against a patient's head they form a cradling area. When the rigid shoulder sections are mated to the base member by means of Velcro-type hook-loop fasteners the device becomes rigid thus restraining the patients head and neck area. Adhesive tape on the bottom of the base member allows for the device to be secured to a surface that further supports the patients cervical area.
