MATTRESS OVERLAY SYSTEM WITH POSITIONALLY ADJUSTABLE, LATERAL RAMP-WEDGE BOLSTER STRUCTURE

摘要

A bolster structure system possesses anti-decubitus ulcer characteristics, and may cooperate with a mattress overlay also having anti-decubitus ulcer capabilities as part of a mattress overlay system, in which multiple elongate, positionally adjustable, relatively moveable bolsters are configured for selective placement in conditions of lateral under-engagement with the sides of an overlay to create inclined, lateral side elevations of these sides at locations along the length of the overlay. The bolster structure and overlay may each include a dynamic-response core expanse formed of an open-cell, compressible viscoelastic foam coated with an elastomeric, moisture- and gas-flow-managing, differential-thickness coating structure load-transmissively bonded to the entirety of the outside of said core expanse to function as a dynamically-responsive unit therewith.

主权项

1. A mattress overlay system, comprising:
a mattress overlay; and a bolster structure, comprised of one or more moveable bolsters configured to be placed beneath the overlay, wherein the overlay and the bolster structures each further comprise:
a core expanse; anda coating structure bonded to the entirety of the outside of said core expanse, with the coating structure in some respiration-window regions being formed to be moisture-pervious and gas-permeable, and in other non-respiration regions being formed to be substantially moisture-impervious and gas-impermeable, and having an outer surface possessing suction-cup-like dimples to provide increased friction against a surface in immediate contact with the outer surface.
