Abstract

An apparatus for transferring a patient or other body comprises a housing, a support bridge at least partially disposed within the housing, and a continuous belt disposed about the support bridge. The housing is formed with first and second sides coupled to first and second ends, and dimensioned to span between first and second surfaces. The support bridge is coupled to the housing, spaced from and supported between the first and second sides to define a channel through the housing. The continuous belt extends through the channel to transfer a body from the first surface at the first side of the housing to the second surface at the second side, with the body supported on the bridge in conveying relationship upon the continuous belt.
