Abstract
An intravenous pole clamp contains a locking mechanism which employs a spring clutch. The clamp body has an attachment for a medical device and a chamber for receiving an I-V pole. A threaded stud is rotated inwardly to clamp the I-V pole. A spring having one fixed end and one free end is threaded onto the shaft of the threaded stud. A locking mechanism allows the free end of the spring to be unrestrained in a locked position. When unlocked, a pin of the locking mechanism slightly unwinds and restrains the free end of the spring freeing the threaded stud to rotate in either an inward or an outward direction. In a locked position, the threaded stud can rotate inwardly but if it is attempted to rotate it outwardly the spring clutches the threaded stud preventing outward rotation.
