Abstract: The present invention provides an intravenous fluid flow regulator (10) for controlling the I.V. administration of medical fluid to a patient. The fluid flow regulator (10) provides a housing (12) having a top (18) and a bottom (20). A flexible diaphragm (14) is positioned within housing (12). A diaphragm holder (16) is provided inside housing (12) for holding a sealing edge (56) of flexible diaphragm (14) in fluid sealing engagement with diaphragm holder (16). The housing (12) and flexible diaphragm (14) define an inlet fluid reservoir (62) and an outlet fluid reservoir (64). The diaphragm holder (16) defines a by-pass fluid channel (54) from inlet fluid reservoir (62), around diaphragm (14), to outlet fluid reservoir (64). The flexible diaphragm (14) being flexible to alternatively move into inlet fluid reservoir (62) and outlet fluid reservoir (64) depending on a fluid pressure differential between inlet fluid reservoir (62) and outlet fluid reservoir (64).

Abstract translation: 本发明提供一种用于控制I.V.的静脉内流体流动调节器（10）。 向患者施用医用流体。 流体流量调节器（10）提供具有顶部（18）和底部（20）的壳体（12）。 柔性隔膜（14）定位在壳体（12）内。 膜片保持器（16）设置在壳体（12）内部，用于保持与隔膜保持器（16）流体密封接合的柔性隔膜（14）的密封边缘（56）。 壳体（12）和柔性隔膜（14）限定入口流体储存器（62）和出口流体储存器（64）。 隔膜保持器（16）限定来自入口流体储存器（62），隔膜（14）周围的旁路流体通道（54）到出口流体储存器（64）。 柔性隔膜（14）根据入口流体储存器（62）和出口流体储存器（64）之间的流体压力差，灵活地交替地进入入口流体储存器（62）和出口流体储存器（64）。
