ABSTRACT:
The disclosed lift/transfer mechanism has a pair of boom arms pivoted at two end corners to a patient gurney, the arms being of sufficient height and length to move the free arm ends to operative positions over the top of the gurney and an adjacent transfer support. A lift strap is dangled from each boom arm to an underlying hook for making a connection to the patient board. Each lift strap is routed via pathways in its respective boom arm to a winch carried on the gurney near the boom arm pivot structure, and the lift strap is released or retracted by winch operation to raise and lower the patient board and suspend it from the boom arms. Boom arm rotation between the operative positions shifts the suspended patient board laterally between the gurney and transfer support. Strap slides moveable freely along the boom arms route the lift straps to keep them hanging vertically between the boom arms and underlying hooks, for maintaining substantially constant patient board height during this lateral transfer.
