Abstract: A ring shaped medical positioner and method for its manufacture the positioner includes a ring shaped insert wrapped in a surgical vinyl. The vinyl is divided into a first and second pieces, the first piece being formed by forming dyes engaging opposite sides of the vinyl, which is stretched between the dyes and progressively relaxed as the material is drawn into the female forming dye by the male dye and suction. The insert is placed within the formed surgical vinyl. The second piece is a flat disc which is placed over one of the surfaces of the insert and sealed to the edges of the first piece of vinyl to thereby provide a wrinkle free covering which may be easily disinfected for repeated use.
