    • A controllable fluid device (20) for rehabilitation of injured or weakened complex appendages such as the hands and feet. The controllable fluid device (20)includes a reservoir (34)which contains a sufficient amount of controllable fluid (52)such as a Magnetorheological (MR) fluid. A magnetic field generator (36)provides the magnetic field (H) which is applied to the controllable fluid (52) by a magnetic circuit (60). In one aspect, an electromagnet including a coil (58) and core (54) provides the magnetic field (H). The intensity of the magnetic field is controlled via a controller (38). In another aspect, the magnetic field (H) is provided by a permanent magnet (44) and a mechanical shunt mechanism (42) is used to vary the magnetic field intensity. Other embodiments include a heater unit (66) with optional thermostat (74).
    • 一种可控流体装置(20),用于修复诸如手和脚之类的受伤或弱化的复杂附肢。 可控流体装置(20)包括储存器(34),其容纳足够量的可控流体(52),例如磁流变(MR)流体。 磁场发生器(36)通过磁路(60)提供施加到可控流体(52)的磁场(H)。 一方面,包括线圈(58)和铁心(54)的电磁铁提供磁场(H)。 通过控制器(38)控制磁场的强度。 另一方面,磁场(H)由永磁体(44)提供,机械分流机构(42)用于改变磁场强度。 其他实施例包括具有可选恒温器(74)的加热器单元(66)。
