Abstract
A support cushion for medical use, especially during surgery, to support the patient's head and neck in convenient positions without patient damage includes two portions made of polyurethane foam separably joined by hook and loop fasteners or the like. The portion normally on top when the two are used together has a hemispherical depression in the top, a groove extending outwardly from the depression, dihedral plane surfaces extending out from the groove and a rectangular bottom surface. The bottom portion has a rectangular top surface, a V-shaped groove in the bottom and planar surfaces on either side of the V-groove lying in a plane which makes an acute angle of about 7.degree. with the plane containing the top.
Claims3
A support cushion, particularly for use in supporting the head and cervical regions of a medical patient, comprising
- a first unitary cushion portion formed entirely of polymeric foam material and having
- a rectangular, substantially planar lower surface,
- means defining a generally hemispherical depression extending inwardly from the upper surface,
- a generally U-shaped groove extending outwardly from said depression generally parallel with said lower surface, and
- dihedral planar surfaces extending symmetrically outwardly and upwardly from said groove and depression;
- a second unitary cushion portion formed entirely of polymeric foam material and having
- a rectangular, substantially planar upper surface, and
- a lower surface having planar side portions lying in a plane forming an acute angle with the plane containing said upper surface of said second portion and
- dihedral surfaces extending symmetrically between the inner margins of said side portions and a line, thereby defining a shallow, V-shaped groove;
- means for releasably interconnecting said lower surface of said first cushion portion and said upper surface of said second cushion portion in parallel adjacent relationship.
