    摘要： An infusion pump for infusing a medical treatment fluid intravenously to a patient includes a collapsible treatment fluid bag juxtaposed with an inflatable drive fluid bladder confined between a pair of opposing containment members which cause the bladder to impinge against the bag as the bladder is inflated. A drive fluid pump controllably inflates the bladder, thereby displacing treatment fluid from the bag into an outlet tube affixed thereto which conveys the treatment fluid to the patient where it is received intravenously. The treatment fluid flow rate through the tube is controlled by increasing or decreasing the drive fluid pump output and consequently the pressure in the bladder in response to a pressure sensor in fluid communication with the bladder. Alternatively, the treatment fluid flow rate is adjusted by opening or closing the outlet tube by means of an occluder or restrictor positioned along the tube.

    摘要： A detachable apparatus for limiting the rate at which a fluid is supplied to a patient by a positive pressure infusion device. The infusion device has an operating device pressure of at least approximately 2 psi. The apparatus includes a constrained flow segment (or CFS), coupleable to and detachable from the infusion device, for delivering fluid to the patient from the infusion device. The CFS has a length, an inside diameter, and a hydraulic resistance. The hydraulic resistance is a function of the length and inside diameter. When the apparatus is not in a free-flow condition, the CFS delivers fluid to the patient at a controlled flow rate determined by the operating device pressure and the hydraulic resistance of the CFS. When the apparatus is in a free-flow condition, the hydraulic resistance of the CFS limits a maximum flow rate of the apparatus to less than about 50% of the controlled flow rate. An adaptor is also provided for enabling a non-activating intravascular set ("IV set") to be used with an infusion device designed to be used only with an activating IV set. The infusion device has a detector element for detecting whether an IV set being used with the infusion device is an activating IV set. The infusion device is activated in response to detection of an activating IV set and is disabled if no such IV set is detected. The adaptor comprises an active element, independent of an IV set, for interacting with the detector element. The active element causes the detector element to detect the presence of an activating IV set when, in reality, a non-activating IV set is being used.

    摘要翻译： 一种用于限制通过正压输注装置将流体供应给患者的速率的可拆卸装置。 输注装置具有至少约2psi的操作装置压力。 该装置包括可与输液装置连接和分离的约束流动段（或CFS），用于从输注装置输送流体给病人。 CFS具有长度，内径和液压阻力。 液压阻力是长度和内径的函数。 当设备不处于自由流动状态时，CFS以由CFS的操作装置压力和液压阻力确定的受控流量将流体输送到患者。 当设备处于自由流动状态时，CFS的液压阻力将设备的最大流量限制在小于受控流速的约50％。 还提供了一种适配器，用于使非活化血管内组（“IV组”）与设计为仅与活化IV组一起使用的输注装置一起使用。 输注装置具有用于检测与输注装置一起使用的IV组是否为活动IV组的检测器元件。 响应于激活IV组的检测而激活输注装置，并且如果不检测到这样的IV组，则禁用输注装置。 该适配器包括与IV组无关的有源元件，用于与检测器元件相互作用。 当实际上使用非激活IV组时，有源元件使检测器元件检测激活IV组的存在。
