Abstract

Abstract A ventilated body positioner device and the like is formed from a block of polyurethane foam having resilient characteristics capable of deformation of the type having a length substantially greater than its width so that the block may be rotated on one of a plurality of major surfaces to provide an adjustable positioning support surface for a major portion of a patient's body while lying upon a table or bed surface wherein various cut-outs and air circulation channels enhance the ventilation capabilities of the device while positioning a patient.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 247 words
A ventilated body positioner for providing lateral support for the body of a patient lying in a side position while providing ventilation and reduced pressure at strategic areas of support, said ventilated body positioner comprising: an elongated positioner block of resilient deformable material having spaced longitudinal end portions and a plurality of planar surfaces on which said block may be rotated and selectively positioned as either a base or body supporting surface extending generally between said ends; said planar surfaces being relatively inclined such that said elongated positioner block based on one of said planar surfaces presents another of said planar surfaces as a longitudinal body support surface having a widened sloping contour for properly positioning the patient in a side-rotated position; said positioner block and hence each said planar surface having a length substantially greater than its lateral width for supporting a substantial portion of the patient's lateral body length; a cavity adjacent end portions of said elongated positioner block formed by cutting out a portion of said block in a plane transverse to the plane of said planar surfaces; and said cavity terminating to define a longitudinally extending edge support surface extending laterally from a main support surface which contact and support an area of said patient's body while said cavity provides ventilation to a non-contacted, supported area of said patient's body adjacent said contacted area reducing the buildup of heat and moisture and pressure at said areas to prevent the formation of decubitus ulcers.
Claim 2
Dependent Claim 247 words
A ventilated body positioner for providing lateral support for the body of a patient lying in a side position while providing ventilation and reduced pressure at strategic areas of support, said ventilated body positioner comprising: an elongated positioner block of resilient deformable material having spaced longitudinal end portions and a plurality of planar surfaces on which said block may be rotated and selectively positioned as either a base or body supporting surface extending generally between said ends; said planar surfaces being relatively inclined such that said elongated positioner block based on one of said planar surfaces presents another of said planar surfaces as a longitudinal body support surface having a widened sloping contour for properly positioning the patient in a side-rotated position; said positioner block and hence each said planar surface having a length substantially greater than its lateral width for supporting a substantial portion of the patient's lateral body length; a cavity adjacent end portions of said elongated positioner block formed by cutting out a portion of said block in a plane transverse to the plane of said planar surfaces; and said cavity terminating to define a longitudinally extending edge support surface extending laterally from a main support surface which contact and support an area of said patient's body while said cavity provides ventilation to a non-contacted, supported area of said patient's body adjacent said contacted area reducing the buildup of heat and moisture and pressure at said areas to prevent the formation of decubitus ulcers.
Claim 3
Dependent Claim 49 words
The structure set forth in claim 1 including longitudinal channel means formed in the interior of said elongated positioner block and bore means communicating with said channel means extending outwardly to one of said planar surfaces so that air is circulated to the supported area of the patient's body.
Claim 4
Dependent Claim 26 words
The structure set forth in claim 2 wherein said channel means is open at opposing ends of said positioner block facilitating the circulation of air therethrough.
Claim 5
Dependent Claim 48 words
The structure set forth in claim 3 including a plug receivable in said channel means to close an end thereof with said other end being open and adaptable for receiving a conveyance of air through said channel means and hence outwardly through said bore means to support surface.
Claim 6
Dependent Claim 32 words
The structure set forth in claim 1 wherein said cavity is formed at opposing corners of said ends facilitating ventilation and reduced pressure in the sacral area of the supported body portion.
