摘要:
A patient lifter is provided which includes a pair of side members with a patient support extending therebetween. Arcuate front supports extend from a first end of each side member and the inside bend of each arcuate front support generally faces the patient support. A handle at a second end of the side members facilitates a lift. As the lift begins, a first mechanical advantage is effected by the patient being relatively close to a fulcrum of the lifter. Large vertical travel by the lifting force results in relatively little vertical travel by the patient. As the lift progresses, and the one doing the lift is in a better position to exert additional lifting force, the fulcrum shifts to provide a second, lower, mechanical advantage, but the patient moves further in the vertical direction relative to the vertical travel of the handle.
