    • A portable rehabilitation device employing a suspension system to enable passive or active range of motion exercise of the knee or hip joint. The device has a base adapted to support the suspension system while the patient reclines to perform the respective leg exercises. The suspension system includes a linear track that retains three shuttles slidably positioned in series along the track attached to flexion, extension and leg support lines respectively. A pair of leg cuffs are connected to the leg support line and suspend the leg while isolating the knee joint. For passive suspension exercise, the leg support line is secured and the leg is suspended by only a single cuff at the ankle with the knee joint in a position of full extension. For passive motion exercise, the leg is suspended by both cuffs and the patient alternately pulls on handles attached to the flexion and extension lines causing alternate passive flexion and extension of the knee and hip joint. The same procedure is repeated for assisted active motion exercise, but the patient partially drives the support line with the leg muscles, thereby augmenting the external drive applied by the handles. For independent active motion exercise, the patient releases the handles and drives the leg support line entirely with the leg muscles.
    • 一种便携式康复装置,其使用悬挂系统来实现膝盖或髋关节的被动或主动运动范围的运动。 该装置具有适于支撑悬挂系统的基座,同时患者倾斜以执行相应的腿部锻炼。 悬架系统包括一个线性轨道,其沿着沿着连接到弯曲,伸展和腿部支撑线的轨迹可滑动地定位的三个梭子保持三个梭子。 一对腿箍连接到腿部支撑线,并且在分离膝关节时悬挂腿部。 对于被动悬架运动,腿部支撑线被固定,并且腿部仅在脚踝处悬挂,膝关节处于完全伸展的位置。 对于被动运动锻炼,腿部由两个袖口悬挂,患者交替地拉动附接到屈曲和延伸线的手柄,引起膝盖和髋关节的被动屈曲和伸展。 对于辅助主动运动训练重复相同的过程,但患者部分地用腿部肌肉驱动支撑线,从而增加由手柄施加的外部驱动。 对于独立的主动运动,患者释放手柄并且完全用腿部肌肉驱动腿支撑线。

    • A portable, patient-controlled medication delivery system includes an infusion pump and a catheter assembly. The infusion pump retains a treatment fluid and provides a drive mechanism for delivering the treatment fluid to a patient via the catheter assembly. The infusion pump includes a fluid reservoir, a dosage chamber, a displacement piston displacable within the dosage chamber, a charge flowpath providing fluid communication between the fluid reservoir and the dosage chamber, and a passive flow restrictor positioned in the charge flowpath. An elastic member is also positioned in the infusion pump to exert an elastic displacement force on the displacement piston, which expands the dosage chamber and draws the treatment fluid from the fluid reservoir into the dosage chamber at a charge flow rate controlled by the passive flow restrictor. When an opposing manual displacement force is exerted on the displacement piston, the dosage chamber contracts and discharges the treatment fluid from the dosage chamber to the treatment site.
    • 便携式,患者控制的药物输送系统包括输液泵和导管组件。 输注泵保持处理流体并提供用于经由导管组件将治疗流体递送到患者的驱动机构。 输注泵包括流体储存器,剂量室,置换剂量室内的置换活塞,提供流体储存器和剂量室之间的流体连通的装料流路,以及定位在充气流路中的被动流量限制器。 弹性构件也定位在输注泵中以在移位活塞上施加弹性位移力,其膨胀剂量室,并且将处理流体从流体储存器以由被动流量限制器控制的电荷流量速率吸入剂量室 。 当相反的手动位移力施加在位移活塞上时,剂量室将处理流体从剂量室收缩并排出到治疗部位。
