图中： 1、背板 2、凸轮 3、拉伸弹性件 4、移动滑块 5、 旋转反应块 6、 滑移挡块 7、 凸台 8、 胶垫 9、 压缩弹性件 10、 圆柱销 11、 轴承 12、 把手 13、 盖板 14、 外壳 15、 封盖 16、对称线 17、旋转轴 18、弧形凹槽 19、台阶 20、 定位槽 具体实施方式
如图 1、 图 2、 图 3、 图 4和图 5所示一种智能闭环识别复位反 馈装置， 包括背板 1， 背板 1的一侧设有外壳 14， 外壳 14上设有盖 板 13， 外壳 14与盖板 13的中间向外伸出有旋转轴 2， 旋转轴 2的端 部设有横向的旋转把手 12， 并用封盖 15固定， 所述的外壳 14内设 有两个移动滑块 4， 这两个移动滑块 4通过拉伸弹性件 3连接， 在这 两个移动滑块 4的中间设有一个凸轮 2， 在两个移动滑块 4相同的部 位设有两个圆柱销 10， 圆柱销 10靠在凸轮 2的边缘； 所述的凸轮 2 半径相等的部分大于凸轮 2的一半；所述的移动滑块 4的下部设有滑 移挡块 6，在滑移挡块 6的内部设有压縮弹性件 9与移动滑块 4作用， 滑移挡块 6的头部内侧沿凸轮 2的边缘方向开有弧形凹槽 18， 在凸 轮 2边缘与弧形凹槽 18相配合的位置上设有凸台 7; 所述的移动滑 块 4的中部滑移挡块 6的上方设有旋转反应块 5， 旋转反应块 5通过 旋转轴 17与移动滑块 4连接，滑移挡块 6上设有一台阶 19与旋转反 应块 5配合； 所述的圆柱销 10的表面上安装有轴承 11 ; 所述的凸轮 2的边缘在与对称线 16相交的位置设有定位槽 19; 所述的移动滑块 4和旋转反应块 5远离凸轮 2的一端设有胶垫 8。
如图 6和图 7所示（a)与 （d) 为旋转的起始位置， （b)与 （e ) 为旋转的中间位置， （c ) 与 （f ) 为旋转的结束位置， 在凸轮 2开始 旋转， 到一侧的移动滑块 4上的圆柱销 10即将进入凸轮 2半径不相 等的区域时，在另一侧的移动滑块 4上的滑移挡块 6在凸轮 2边缘上 扫过的最短区域上设置凸台 7， 此最短区域关于凸轮 2对称线 16对 称的； ^一区域内也设有相同的凸台 7; 所述的两个凸台 7的位置与凸 轮 2的圆心在一条直线上； 为了在操作上方便，所述的两个凸台 7关 于凸轮 7的对称线 16对称。 图 6所示扫过的区域较图 7所示扫过的 区域大， 为了使此装置无论如何旋转都不会有掉杆现象发生， 选择图 6和图 7所示区域的重合部分， 即为图 7所示的区域， 图 7所示区域 关于对称线 16对称的区域也设置凸台 7。
如图 8、 图 9 图 10所示为正常操作此装置的基本步骤， 在需 要转 输液系统的时候， 在右端放置与左端直径相同的竖杆， 转动旋 转把手 12， 带动凸轮 2转动， 当凸轮 2转动使得圆柱销 10和轴承 11 进入凸轮半径相等部位时， 右侧旋转反应块 5被外力施压， 带动右侧 滑移挡块 6同时被压下， 并在压縮弹性件 9的作用下沿着移动滑块 4 的导向槽向转动凸轮 2轴心运动，由于安装在移动滑块 4上的圆柱销 10和轴承 11， 以及拉伸弹性件 3的集合作用下， 凸轮 2带动两边的 移动滑块 4分别做^反方向的横向运动。凸轮 2沿外边缘 180度处各 有两! ^台 7， 所以当凸轮 2转到接近 90度， 并且确认两边的旋转反 应块 5被外力完全压下的情况下，凸轮 2沿外边缘 180度处的两个凸 台 7能够顺利通过前后两面的滑移挡块 6的弧形凹槽 18， 则此时操 作者能够正确、顺利且安全地完成该输液转运系统的使用。 当旋转把 手 12旋转了 180度， 此次转移安全完成。
如图 11为在安全转移的条件没有达到的情况下， 即装置两边所 放置的竖杆的直径不一致时，旋转反应块 5没有被外力完全压下即压 力不足，凸轮 2外边缘 180度处的两个凸台 7不能够顺利通过前后两 面的滑移挡块 6上的弧形凹槽 18， 则旋转把手 12就不能够向需要转 动的 向转动， 这样就阻止了操作人员的继续使用， 一直到操作人员 在正确的使用条件下才能正常运转。
如图 12所示可以清楚的看到当旋转反应块 5的压力不足 （即竖 杆的直径达不到要求）时， 滑移挡块 6不能够被完全压入， 从而导致 了凸台 7不能够顺利的通过弧形凹槽 18， 使操作不能够正常的进行。
