Abstract
Abstract A limb support and the like is formed from a block of polyurethane foam having resilient characteristics, capable of permitting the passage of air and being of such configuration as to include a continuous open topped arcuate groove extending longitudinally along the length of the block for receiving, cradling and resiliently gripping the limb of a hospitalized patient to avoid rotation of the limb supported thereby.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
237 words
A support device for a patient's lower limb for use when the patient is confined to a bed to prevent turning of the limb comprising: A. an elongated block of resilient deformable polyurethane foam material; B. a flat bottom surface providing an elongated base for placement upon the bed surface: C. a pair of spaced substantially vertical side surfaces; D. a top planar surface inclined with respect to said bottom surface, and E. an open continuous elongated arcuate groove of uniform cross section formed in said top planar surface along the entire length thereof defining first and second spaced inclined planar top portions extending the entire length of said block, said groove being inclined with respect to said bottom surface and being substantially semicircular in extent for providing a cradle for supporting and gripping a limb from a portion thereof adjacent the ankle to a portion thereof adjacent the knee; whereby when a limb is placed in said central groove of the support, the support will deform over its entire length under the weight thereof exerted on a central lower portion of the groove causing depression of the resilient material therebeneath and inward flexing of upper portions of the groove tending to bring together said first and second top portions with resilient gripping of the limb within the entire length of said groove, thus avoiding turning of the limb while supporting the limb in an elevated position.
