    • A magnetic levitation system for immobile patients in a wheelchair is disclosed. A magnet multi-pole configuration that is mechanically stable is provided that lifts the body and/or load shifts (rotates the body from side to side) the body. Based on a multi-pole configuration of permanent magnets in the pelvis, a corresponding multi-pole configuration for magnet repulsion is placed below the patient, typically as part of the wheelchair. Alternatively, a unipolar repulsion with mechanical patient restraint is implemented to achieve body lift or levitation. Either permanent magnets or electromagnets, optionally with magnetic sensor-mediated active computerized feedback control below the body, are sufficient to implement a complete multi-pole repulsive configuration that is mechanically stable. The apparatus reduces compressive force on soft tissues disposed between a human pelvis and a wheelchair seat.
    • 公开了一种用于轮椅上不动的患者的磁悬浮系统。 提供机械稳定的磁体多极配置,其提升身体和/或负载(身体从一侧到另一侧)使身体移动。 基于骨盆中的永磁体的多极配置,用于磁体排斥的相应的多极配置被放置在患者的下方,通常作为轮椅的一部分。 或者,实施具有机械患者约束的单极排斥以实现身体升力或悬浮。 任何一个永磁体或电磁体,任选地具有磁性传感器介导的主体的主动计算机化反馈控制,足以实现机械稳定的完整的多极排斥构造。 该装置减少了设置在人骨盆和轮椅座椅之间的软组织上的压力。
