ABSTRACT:
An extrication collar for immobilizing the head and neck of an injured victim is field adjustable by an emergency medical technician who matches the size of the victim by tearing lower and/or upper peripheral portions of the extrication collar off along a perforated line. The vertical height of the collar and hence the length of neck to which the collar is adjusted is varied by the amount of the collar periphery, which is removed by manually tearing along a perforated line. The plurality of perforated lines are defined through the collar to provide a plurality of discrete sizes. Rigidity of the collar is provided by an exterior and noncompressible foam layer, while cushioning of the collar is provided by an interior compressible foam bonded to the noncompressible foam. The noncompressible foam or the compressible foam or both are selectively separable through the perforated lines in the front portion of the collar, the back portion of the collar or both.
