A retractor assembly for engaging a sheet on which a patient is disposed includes a transverse member and a pair of tethers coupled to the transverse member and extending from the transverse member for coupling to a winding assembly. A pair of sheet clamps are mounted to the transverse member, which are spaced apart along the longitudinal axis of the transverse member in a fixed spaced relationship for engaging a sheet at two points spaced along the longitudinal axis. The transverse member maintains the sheet clamps in their fixed spaced relationship whereby the sheet clamps resist inward migration toward each other when being used to handle a patient on a sheet.

Patient transfer device

A patient transfer device includes a base assembly movable in forward and lateral directions. A power train is mounted within the base assembly, and is connected to a clamping and strap assembly. A power and switching system is in electrical communication with the power train. A retractor bar carries one or more clamping devices that are releasably attachable to a sheet. The clamping devices include a clamp handle pivotally connected to a clamp base and a clamp arm eccentrically pivotally connected to the clamp handle. The clamping and strap assembly is supported on the base assembly by a vertical adjustment assembly that includes a positioning mechanism for releasably locking the clamping and strap assembly at one of a plurality of vertical positions. An attendant can stand on the base assembly to act as a counterbalance to a patient's weight.
