| 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. |

1. A patient lifter apparatus, comprising:
first and second spaced side members, each side member having a first end and a second end; a patient support, the patient support extending between the first and second side members proximate the first ends of the side members and adapted to at least partially rotate relative to an axis substantially perpendicular to the first and second side members, the axis located inboard of the front and back edges of the support, the patient support further adapted to substantially maintain at least a portion of the weight of the patient over the axis; and first and second spaced arcuate front supports, each front support extending from the first end of the first and second side members, respectively, an inside bend of each front support generally facing the patient support, wherein the arcuate supports provide a lifting mechanical advantage.
