    • A first object is to offer a safety device that allows to effectively solve problems regarding transfusion including free-flow issues in the case where the transfusion tube comes off from the transfusion pump, by employing a comparatively simple structure constructed at a low cost. A second object is to offer a safety device that can be newly added to an existing transfusion pump having no safety device. Specifically speaking, the case 100 in a tubular shape having a base, the compression spring 130, and the clamp 10 having the movable body 120 are set in the socket 20 having a cross-sectional shape of a square bracket. When the clamp 10 is set in the socket 20, the through-holes 101 and 121 become open, which allows distribution of fluid in the transfusion tube. On the other hand, when the clamp 10 becomes detached from the socket 20, the tension of the compression spring 130 causes the movable body 120 to slide, and the through-holes 101 and 121 are closed. As a result, the transfusion tube is blocked off, preventing the occurrence of a free flow.
    • 第一个目的是提供一种安全装置,通过采用以较低成本构造的比较简单的结构,能够有效地解决在输血管从输血泵中脱出的情况下的输血问题,包括自由流动问题。 第二个目的是提供一种可以新添加到没有安全装置的现有输液泵中的安全装置。 具体来说,具有底座的管状形状的壳体100,具有可移动体120的压缩弹簧130和夹具10设置在具有正方形支架的横截面形状的插座20中。 当夹具10设置在插座20中时,通孔101和121变得开放,这允许流体在输液管中分配。 另一方面,当夹具10从插座20脱离时,压缩弹簧130的张力使可动体120滑动,并且通孔101和121被关闭。 结果,输血管堵塞,防止自由流动的发生。
