Abstract:
1. A bed comprising: an undercarriage frame; a patient surface frame opposite the undercarriage frame; a plurality of height-adjustable lifters disposed between the undercarriage frame and the patient surface frame and configured to move independently of one another, each of the plurality of height-adjustable lifters comprising a first end coupled with the undercarriage frame and a second end coupled with the patient surface frame, the plurality of height-adjustable lifters configured to move the patient surface frame with respect to the undercarriage frame in a predetermined range of motion; at least one load-cell-supporting surface disposed parallel to the undercarriage frame and coupled with the second end of one of the plurality of height-adjustable lifters, wherein the load-cell-supporting surface remains parallel to the undercarriage frame throughout the range of motion, and wherein the range of motion comprises a position where the patient surface frame is rotated about its longitudinal and transversal axes so that it is oblique to the undercarriage frame; wherein the plurality of height-adjustable lifters comprises a first height-adjustable lifter intersecting a longitudinal axis of the patient surface frame, a second height-adjustable lifter, and a third height-adjustable lifter; and wherein the second and third height-adjustable lifters are coupled by an arm disposed transversely to the longitudinal axis of the patient surface frame, and wherein the arm is coupled with the patient surface frame via an intermediate plate structure.
