为使本发明的目的、技术方案和优点更加清楚， 以下结合附图及 具体实施例， 对本发明作进一步地详细说明。 根据本发明的实施例， 提供了一种球嚢压力泵。
下面结合图 1和图 2描述本发明，其中图 1是根据球嚢压力泵的 组合结构的示意图，图 2是根据本发明实施例的球嚢压力泵的分解结 构的示意图。 为使便于理解， 下述实施例中的相同元件以相同的符号 标示来说明。
如图 1和图 2所示， 该球嚢压力泵 100主要包括： 腔体 1 , 推杆 2, 手柄 3, 锁定部件 4, 套筒 5, 下面分别详细描述。 腔体 1为圓柱体设计， 其内部为中空内腔结构， 能够容置药液。 腔体 1包含末端和近端， 其末端具有与高压管连接的接头， 其近端为 开口结构， 推杆 2从腔体 1的近端插入到腔体 1的内部。 一般地， 腔 体 1的上部为透明设计，便于操作者的观察腔体 1内药液的情况， 并 且腔体 1上还设置有与其内液体体积对应的刻度。
推杆 2包含末端和近端， 其设置有外螺纹， 推杆 2的末端从腔体 1的近端插入到腔体 1的内部， 推杆 2的末端连接有密封圏座（图中 未示） ， 密封圏座通过外围密封表面滑动接合在腔体 1的内表面， 形 成可移动密封结构。
手柄 3为内部中空的圓柱形结构， 其内部可以放置套筒 5。 手柄 3与推杆 2的近端固定连接， 当操作手柄 3前后动作时， 推杆 2也能 够随着手柄 9的动作进行前后动作，并且，当操作手柄 3旋转动作时， 推杆 2也能够随着手柄 9的动作进行旋转动作， 例如： 当顺时针旋转 手柄 3时， 推杆 2就相应地向前（末端）移动。 一般地， 手柄 3设计 为便于操作的外形， 例如： 在手柄 9上设置增加摩擦力的凸筋。 锁定部件 4包含末端和近端， 设置在推杆 2的近端， 锁定部件 4 的末端与腔体 1的近端固定连接，锁定部件 4的近端与套筒 5固定连 接。 锁定部件 4用于锁定推杆 2, 锁定部件 4的中间开有使推杆 2通 过的透孔， 其底部具有与推杆 2的螺紋相啮合的螺纹， 并且， 锁定部 件 4上设置有锁定推杆 2的按键 41 , 当抬起按键 41时， 推杆 2的螺 纹与锁定部件 4底部的螺纹互相啮合， 推杆 2被锁定，推杆 2不能够 自由地通过锁定部件 5的透孔，而只能够通过旋转手柄 3而旋转地进 行前后动作； 当按下按键 41时， 推杆 2被释放， 推杆 2可以自由地 前后动作穿过锁定部件 5的透孔。 需要说明的是，推杆 2的前后或旋 转动作都是通过操作手柄 3而完成的。 手柄 3内设有套筒 5 , 套筒 5用于容置推杆 2, 套筒 5与锁定部 件 4的近端固定连接。当向后拉动手柄 3时，带动推杆 2也向后动作。 这时， 推杆 2就在套筒 5的内部动作。
请参考图 3A和图 3B , 图 3A是本发明实施例的球嚢压力泵的轴 向剖面图， 如图 3A所示， 该球嚢压力泵包括： 腔体 1 , 推杆 2, 手 柄 3 , 锁定部件 4, 按键 41 , 按键簧 42, 对开螺母 43 , 套筒 5 , 密封 圏座 6, 卡环 7, 0型密封圏 8 , 第一高压管出口 9, 第二高压管出口 10。
图 3A中与图 2相同的部件此处不再赘述。 此外， 卡环 7与密封 圏座 6固定连接， 卡环 7用于连接推杆 2和密封圏座 6, 推杆 2的末 端为凸台设计， 卡环 7卡接在推杆 2的凸台， 从而使推杆 2和密封圏 座 6紧密连接。 并且， 为保证良好的密封效果， 密封圏座 6上还设置 有 0型密封圏 8。 腔体 1的末端设置有第一高压管出口 9和第二高压管出口 10, 第一高压管出口 9上的高压管与压力显示装置连接，第二高压管出口 10上的高压管与置入人体的球嚢导管连接。
其中， 压力显示装置进一步包括： 压力传感器， 用于检测泵体和 球嚢导管内的压力信号， 并将该压力信号转换为电信号； 显示单元， 用于接收电信号， 并根据电信号显示压力数据， 时间以及压力曲线等 参数， 并可通过外部 PC将整个过程的数据打印出来。
图 3B是图 3A的 A-A径向剖面图， 如图 3B所示， 锁定部件 4 内设置对开螺母 43用于锁定推杆 2, 锁定部件 4的上部是按键 41 , 下部设置有按键簧 42。 当按键 41被抬起时锁定推杆 2, 推杆 2被对 开螺母 43锁定， 推杆 2只能够相对对开螺母 43旋转， 而不能够直接 前后动作；按键 41被按下时释放推杆 2,推杆 2被对开螺母 43释放， 推杆 2能够直接前后动作。
在实际应用过程中，当向后动作推杆 2时，由于需要产生负压力， 所以需要对推杆 2向后拉动， 这对使用者来说很不方便。 因此， 根据 本发明的实施例， 在推杆 2上设置弹簧， 具体的弹簧设置的位置请参 考图 4A。
如图 4所示， 根据本发明的一个实施例， 在推杆 2的近端设置弹 簧 11 , 弹簧 11被推杆 2封闭在套筒 5内。 在实际使用时， 首先， 将 锁定部件 4的按键 41设为按下状态（即推杆 2被释放）， 弹簧 11向 后 （近端 )推动手柄 3 , 腔体 1内吸入药液， 不可避免的也会吸入少 量空气， 将腔体 1末端向上抬起并向前推动手柄排除空气； 将球嚢导 管送入人体， 球嚢压力泵与球嚢导管连接，按下按键 41弹簧 11后推 手柄 3以形成负压将球嚢导管内的气体和液吸入腔体 1。 这时， 因腔 体 1末端向下， 药液阻隔气体， 向前（末端）推动手柄 3 , 推不动时 抬起按键 41锁住推杆 2, 旋转手柄 3使推杆 2旋转向前移动， 同时 推动密封圏座 6向前移动， 使药液进入球嚢导管， 将药液压入球嚢导 管， 随着压力的增加球嚢被打开加大， 支架被扩张成形， 同时弹簧 11被压缩； 在 X光机的监视下， 再次按下按键 41 , 推杆 2被释放， 手柄 3在在被压缩的弹簧 11的作用下向后运动， 球囊导管内再次形 成负压，球嚢导管中的液体被抽出，球嚢收缩与支架脱离，抽出导管， 完成支架的安装。
综上所述， 通过根据本发明实施例提供的球嚢压力泵， 通过筒单 的结构在进行加压、 泄压、 以及负压等操作时， 筒化了操作步骤， 极 大地方便了使用者。
以上所述仅为本发明的实施例而已， 并不用于限制本发明， 对于 本领域的技术人员来说， 本发明可以有各种更改和变化。 凡在本发明 的精神和原则之内， 所作的任何修改、 等同替换、 改进等， 均应包含 在本发明的权利要求范围之内。
