    • An apparatus having an elongated base from the proximal end of which a reclining patient's leg is extended to an elevated connection of the foot with a foot rest. Mechanism is provided for moving the foot rest so that the hip and knee may be mobilized to the exclusion of the ankle or vice-versa, by applying forces similar to those applied manually by a physiotherapist. This mechanism translates the longitudinal reciprocal stroke of a motor driven carriage into a combination longitudinal and arcuate motion of the foot rest. The foot rest is mounted on the upper end of an actuating arm whose lower end has a pivotal connection with a carriage movable along the base, in linear strokes, toward and from the proximal end. A control beam has a pivotal connection to the upper end of the arm and is provided with a proximally extending frame for connection to the base to hold the beam in a position spaced from the proximal end with the arm held for pivotal movement relative to the upper end of the beam whereby the ankle only is mobilized with the knee and hip joints immobile. A catch mechanism is provided for locking the beam against pivotal movement relative to the arm whereby with the supporting frame free of the base and adjacent the leg, the patient's hip and knee joints are mobilized, with the ankle joint immobile. A reversible motor moves the carriage back and forth in linear strokes. A potentiometer measures the angular position of the actuating arm and is connected to the motor control whereby the length of the strokes is governed by setting limits on the angular movement of the actuating arm, regardless of the position of the carriage on the base. Mounting legs extend from the base, to mount the machine from fixed objects, through terminal clamps of unique construction.
    • 一种具有从其近端延伸的细长基座的装置,斜躺患者的腿部延伸到足部与搁脚架的高架连接处。 提供了用于移动脚踏板的机构,使得可以通过施加类似于由物理治疗师手动施加的力而将髋关节和膝盖动员到排除脚踝或反之亦然。 该机构将马达驱动托架的纵向往复行程转换成脚踏板的纵向和弓形运动。 脚踏板安装在致动臂的上端,其下端具有与沿基座一致的支架的枢轴连接,该线座以线性行程朝向和近端移动。 控制梁具有与臂的上端的枢转连接,并且设置有向近侧延伸的框架,用于连接到基座以将梁保持在与近端隔开的位置,臂保持为相对于上部的枢转运动 梁的端部,由此脚踝只能用膝盖和髋关节固定地移动。 提供了一种锁定机构,用于将梁抵抗相对于臂的枢转运动,由此由于支撑框架没有基座并且邻近腿部,因此踝关节不动,患者的髋关节和膝关节被动员。 可逆电机以线性行程来回移动滑架。 电位器测量致动臂的角度位置并连接到电动机控制器,由此通过对致动臂的角运动设定限制来控制行程的长度,而不管车架在底座上的位置如何。 安装脚从底座延伸,将机器从固定物体上安装,通过独特结构的端子夹。

    • An active human limb manipulation device utilizes a frame to which a carriage is slidably mounted for vertical movement. A sub-carriage is movably mounted to the carriage for horizontal movement and carries the limb of a patient along a predetermined path. Both carriage and sub-carriage are powered by a pair of rodless cylinders which are controlled by a computer control system which simulates normal walking movement so as to strengthen and stretch the limbs of a patient who otherwise lacks the strength and muscle tone associated with normal limb movement. The cylinders have yokes which are fixed to the carriage and sub-carriage and retained in position on the cylinders by a magnetic attraction. When the patient's resistance to movement reaches a predetermined level, the yoke will break the magnetic bonds with the cylinder piston so as to avoid overstressing the limbs of the patient. The yoke may be supplied with an electromagnet so that the magnetic attraction can be closely controlled.
    • 主动人体肢体操纵装置利用滑架可滑动地安装用于垂直运动的框架。 子托架可移动地安装到滑架上用于水平运动,并沿着预定路径携带病人的肢体。 托架和副托架由一对无杆缸提供动力,该对无杆缸由计算机控制系统控制,该计算机控制系统模拟正常步行运动,以便加强和拉伸患者的四肢,否则其中缺乏与正常肢体相关的强度和肌肉紧张 运动。 气缸具有固定到滑架和副滑架上并且通过磁吸引力保持在气缸上的位置的轭。 当患者的运动阻力达到预定水平时,轭将破坏与气缸活塞的磁粘结,以避免患者肢体的过度应力。 轭可以被提供有电磁体,使得磁吸引力可以被紧密地控制。
