Gas-Filled Patient Positioner

Abstract

A gas-filled patient positioner for positioning a body part of a patient comprises a plurality of bladder structures mounted on top of and overlapping each other. Each bladder structure includes a pair of adjacent elongated gas-filled bladders with the inboard side of each of the bladders facing or abutting each other. At least one bleed channel extends transversely between and in communication with the adjacent pair of bladders. The plurality of bladder structures is tightly encased within an elongated outer covering that includes an array of seams that define channels in top and bottom surfaces of the covering to provide pathways for heat and moisture to escape. The array of seams includes a single seam extending along the length of the bladder structures and arranged over the bleed channel, and a plurality of transverse seams extending across a width of the top and bottom surfaces of the outer covering.
