摘要： The present invention is directed to valves for use in controlling the flow of fluid and, more particularly, to a triggerable passive valve for use in controlling the flow of fluid. In one embodiment, a fluid delivery channel is connected to a flow restrictor and a passive valve positioned in the fluid delivery channel downstream from the flow restrictor. The first passive valve prevents fluid from moving through the channel when the pressure exerted by the fluid on the first passive valve is below the burst pressure. A pneumatic actuator actuates the valve by forcing fluid through the passive valve.

摘要： Systems and methods of detecting occlusions and fluid-loss conditions (e.g., disconnects and/or leakages) in an infusion pump are discussed. For example, electrokinetic infusion pumps may develop an occlusion in the fluid flow path, which can disrupt control of fluid dispersed from the pump. As well, an infusion set disconnect can also result in a fluid-loss that can be disruptive. Such disruptions can be troublesome to systems that control the infusion pump, such as closed loop controllers. Accordingly, systems and methods described herein can be used to detect such occlusions and fluid-loss conditions during infusion pump operation. For example, a position sensor can be used to monitor fluid flow from the infusion pump, with the measurement being compared with an expected value to detect an occlusion or fluid-loss condition. Other algorithms for utilizing the position sensor are also described.
摘要翻译：讨论了检测输液泵中的闭塞和流体损失状况（例如断开和/或泄漏）的系统和方法。例如，电动输液泵可能在流体流动路径中产生阻塞，这可能破坏从泵分散的流体的控制。同样，输液器断开也可能导致流体损失，这可能是破坏性的。对于控制输液泵的系统，例如闭环控制器，这种中断可能是麻烦的。因此，本文所述的系统和方法可用于在输注泵操作期间检测这种闭塞和流体损失状况。例如，位置传感器可用于监测来自输注泵的流体流动，其中测量值与预期值进行比较以检测堵塞或流体损失状况。还描述了用于利用位置传感器的其它算法。
