Orthopedic pillow and sizing kit therefor

Claim 1

A sizing kit for determining an appropriate size of orthopedic pillow for use by a patient, said orthopedic pillow comprising a block comprising a deformable material, said block having a substantially quadrilateral perimeter when viewed in plan; an upper surface of said block having a substantially airfoil-shaped reverse curved surface when said block is viewed in elevation; and a groove provided in said upper surface, said groove being sized and adapted to accommodate the cervical vertebrae of a user of said orthopedic pillow, said sizing kit comprising: an ordered multiplicity of members, each of said members having a substantially quadrilateral perimeter when viewed in plan, each of said substantially quadrilateral perimeters of said multiplicity of members having a substantially common first characterizing dimension and a second characterizing dimension, said second characterizing dimensions increasing from ordered member to ordered member such that the number of distinct second characterizing dimensions corresponds to the number of said multiplicity of members; each of said members having an upper surface which comprises a substantially airfoil-shaped reverse curved surface when said members are viewed in elevation; and each of said ordered multiplicity of members, other than a first member of said ordered multiplicity, having a lower surface which substantially corresponds to said substantially airfoilshaped reverse curved upper surface of the preceding member in said ordered multiplicity; whereby said ordered multiplicity of members may be stacked one upon the other according to order to produce a compact and therefore readily storable package.
