    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。

    摘要： An infusion pump (e.g., an electrokinetic infusion pump) includes an infusion pump module and an engine that can drive a moveable piston non-mechanically. In addition, the infusion pump module includes a position detector configured for sensing a dispensing state of the infusion pump module. Such information can be utilized in a control scheme to control fluid displacement within and out of the pump. Descriptions of different types of position detectors, such as magnetic sensors (e.g., an anisotropic magnetic resistive sensor), and their implementation in detecting infusion pump fluid displacement are described.

    摘要： A medical device pump with a housing with a compartment for removably receiving a cartridge containing a therapeutic agent, a conduit configured to operatively provide a fluid flow path for therapeutic agent to exit from the cartridge, a user activated delivery button, a trigger mechanism, and a mechanical pump mechanism. The trigger mechanism, user activated delivery button and mechanical pump mechanism of the medical device pump are configured such that the trigger mechanism is activated by a user fully activating the user activated delivery button. Moreover, such full activation generates mechanical power employed by, and sufficient for, the mechanical pump mechanism to pump a predetermined volume of therapeutic agent from the cartridge and through the fluid flow path.

    摘要： A method for inserting a flexible medical device conduit includes adhering a flexible conduit insertion medical device, with a flexible medical device conduit and an integrated insertion mechanism, to a target site. Moreover, the flexible medical device conduit has an elongated framework formed from a flexible material (e.g., Nitinol) with a body portion, sharp head, distal end and proximal end. The flexible medical device conduit also has a flexible tube at least partially jacketing the elongated framework between the distal end and the proximal end. In addition, the sharp head is disposed at the distal end and is configured for subcutaneous skin insertion and the elongated framework and flexible tube define at least one conduit between the elongated framework and the flexible tube, the conduit having an opening at the distal end. The insertion mechanism is operatively connected to, and integrated with, the flexible medical device conduit and the insertion mechanism is configured to insert a portion of the flexible medical device conduit, including at least the sharp head and the opening, into a user's skin target site. The method also includes inserting the flexible medical device conduit into the target site by action of the insertion mechanism.
