    Abstract: Systems and methods for detecting an occlusion in an infusion device are disclosed. One method includes generating, during an infusion session at predetermined intervals, a feature vector comprising an initial measurement of a physical force caused by fluid motion through an infusion device at the start of an infusion session, a current measurement of the physical force, a long term change in the measurement of the physical force, and a short term change in the measurement of the physical force. The feature vector is inputted, during the predetermined intervals, into a support vector machine (“SVM”) to output an indication of a presence or an absence of an occlusion in the infusion device. The SVM may be trained using reference data from reference infusion sessions having known consequences regarding the presence or the absence of an occlusion at various times during the reference infusion sessions.

    Abstract: A system and method for determining a concentration of total chlorine in dialysis water are provided. The system comprises a main unit housing an iodide/water sample chamber and a reducing agent chamber. An electrode pair bridges the two chambers and generates tri-iodide proportional to the amount of total chlorine in the dialysis water. The electrode pair detects the amount of tri-iodide generated in proportion to the amount of active chloride in the dialysis water. The system is suitable for use in connection with, or for incorporation into, a water purification system for generating dialysis fluid, and may include a display that alerts the user to stop or prevent a hemodialysis treatment if the total chlorine level exceeds a predetermined level.

    Abstract translation: 提供了一种用于测定透析水中总氯浓度的系统和方法。 该系统包括容纳碘化物/水样品室和还原剂室的主单元。 电极对桥接两个室，并产生与透析水中总氯量成比例的三碘化物。 电极对检测与透析水中的活性氯化物的量成比例地产生的三碘化物的量。 该系统适用于与用于生成透析液体的水净化系统相关联或用于并入用于产生透析液体的水净化系统，并且可以包括如果总氯水平超过预定水平则警告用户停止或防止血液透析治疗的显示器。
