Patent ID: 8347889

Claim:
A positioning device to maintain a patent airway by correctly positioning a patient's head during an operation or procedure, comprising: at least one adjustable support arm including a plurality of segments or sections selectively positionable relative to adjacent segments or sections and selectively lockable relative to each other; a patient engaging member coupled to a proximal end portion of the support arm, to engage a portion of the patient's head and restrain the patient's head during an operation or procedure; a base; a distal coupling device for coupling the adjustable support arm to the base; the distal coupling device comprising: a first distal coupling device having (a) an attachment member that pivotally couples to the base by a mounting plate including a recess with a spacer having a groove formed on the upper surface of the spacer, and (b) a bias coupled to the mounting plate to selectively maintain the attachment member in a first or operative position, and a second or open position; and a second distal coupling device to couple said adjustable support arm to said base, the second distal coupling device including a coupling base mounted to a handle having a lever pivotally coupled thereto and being movable between a first or lock position and a second or release position, to cooperatively form an attachment member slot to receive the attachment member therein to secure the adjustable support arm to the attachment member when in the first or lock position and to release the adjustable support arm from the attachment member when in the second or release position.
