Abstract
Abstract A restraining cuff 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 substantially cylindrical internal wall extending longitudinally of the block for receiving the extremities of a hospitalized patient so as to provide a closed circumferential layer of resilient deformable material which may be connected as by a flat strap to the patient so as to distribute the weight of the extremity upon a substantial area of foam and cushion against bruises and other forms of injury to the patient.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
216 words
A restraining cuff and the like comprising: restraining means for placement upon the extremities of a patient confined to prolonged bed rest for elevating the extremities, and for restraining undesireable movement of a patient reclining upon a bed; said restraining means including, an elongated block of resilient deformable polyurethane foam material; said elongated block including a bore therethrough defining a continuous internal wall extending longitudinally of said elongated block for receiving an extremity: said restraining means further defining a thickened, closed integral circumferential cylindrical layer of resilient deformable material, wherein the distance in cross section from said internal wall to the perimeter of said layer maintains an extremity placed within said wall in elevated position above a mattress of the bed so as to avoid pressure point contact between the extremity and the mattress as would result in the formation of decubitus ulcers; a strap encircling a medial outer portion of said block and extending free of said block providing a tie portion for fastening to the bed; and adjustable fastening means for securing said strap encircling the block constricting said circumferential layer of foam resiliently engaging an extremity of a patient; whereby chaffing of the extremity engaged by the cuff may be avoided and the extent of contact between the extremity and the mattress reduced.
Claim 2
Dependent Claim
216 words

Claim 3
Dependent Claim
37 words
The structure set forth in claim 1 wherein said internal wall is positioned longitudinally eccentrically of said block, whereby the block may be positioned on the extremity to position same at a selected height above the mattress.
