The Arm Support allows the patient’s arm to be placed in anatomically correct positions per the patient orientation. The Arm Support will be required to accommodate support of the upper extremities for patients weighing up to 500 lbs. and will be required to maintain positional stability for an arm size range encompassing 2% female to 98% male. The Arm Support also will be required to serve as a restraint when the patient is in the supine position and the arm is tucked along the edge of the table.
Manipulation
Installation of the arm board on the side rail, and angular and linear adjustments, shall be able to be done by a single individual
Activating the release mechanism for enabling yaw, pitch and roll and repositioning the arm board may be done with one hand
The release mechanism for enabling yaw, pitch and roll and repositioning the arm board may be located at the distal end of the arm board
Enabling vertical repositioning and adjustment of the arm board may require two hands
The release mechanisms for vertical repositioning and side rail location adjustment of the arm board may be located near the proximal end of the arm board
Repositioning of the arm board along the side rail shall not affect pitch, yaw, roll, or vertical orientation
Repositioning of the arm board along the side rail may require two hands
