该膝关节主动功能锻炼辅助装置的结构由方形软皮垫、气压把手、条形软皮垫、脚底板、合金拉杆、转轴、底盘及插入组合等组成。适用范围：本装置适用于膝关节周围骨折术后或粘连松解术后进行床旁主动功能锻炼的患者。The structure of the knee joint active function exercise auxiliary device is composed of a square soft leather pad, an air pressure handle, a strip-shaped soft leather pad, a foot plate, an alloy pull rod, a rotating shaft, a chassis and an insertion combination. Scope of application: This device is suitable for patients who perform bedside active functional exercises after fractures around the knee joint or after adhesion release.
具体用法：患者坐在床边，双上肢放于方形软皮垫上，起到支撑作用，气压把手可以控制装置的整体高度，患肢腘窝放于条形软皮垫上，脚放于底板，合金拉杆可根据小腿的长度进行调节，转轴可旋转至对侧，用于另一侧肢体，同时可以上下调节，底盘可旋转并固定，插入组合使整体更加牢固，这样方便患者主动活动膝关节，使之达到生理所需角度，舒适安全可靠。Specific usage: the patient sits on the side of the bed, puts both upper limbs on the square soft leather pad to play a supporting role, the air pressure handle can control the overall height of the device, the popliteal fossa of the affected limb is placed on the strip-shaped soft leather pad, the feet are placed on the bottom plate, and the alloy The pull rod can be adjusted according to the length of the calf, the rotating shaft can be rotated to the opposite side, used for the other limb, and can be adjusted up and down at the same time, the chassis can be rotated and fixed, and the insertion combination makes the whole body more firm, which is convenient for the patient to actively move the knee joint. It is comfortable, safe and reliable to achieve the angle required by physiology.
该膝关节主动功能锻炼辅助装置的气压升降杆中配置有一个气缸，气缸内灌装1～2个大气压的氮气，并用密封圈密封，气缸内的活塞杆在压力作用下可以上下移动，与调节手柄（即锁定装置）相配合，即可实现升降伸缩功能。气压升降杆具有成本低廉、结构简单、操作灵活的特点。气压升降杆采用自锁式气压升降杆，即升降伸缩度在调整好后自锁伸缩度。The air pressure lifting rod of the knee joint active function exercise auxiliary device is equipped with a cylinder, which is filled with 1 to 2 atmospheres of nitrogen and sealed with a sealing ring. The piston rod in the cylinder can move up and down under the action of pressure. The handle (that is, the locking device) cooperates to realize the lifting and telescopic function. The pneumatic lifting rod has the characteristics of low cost, simple structure and flexible operation. The air pressure lifting rod adopts a self-locking air pressure lifting rod, that is, the lifting expansion degree is self-locking after adjustment.
