    • A processor of a medical device configured to communicate with a remote server can be programmed to protect the medical device from exposure to unauthorized or malicious software. A system or method to implement this form of protection can include, for example, at least one processor on the medical device, a control software module that controls the operation of the medical device and is executable on the processor, a data management module that manages data flow to and from the control software module from sources external to the medical device, and an agent module that has access to a limited number of designated memory locations in the medical device. In addition, a hemodialysis apparatus can be configured to operate in conjunction with an apparatus for providing purified water from a source such as a municipal water supply or a well. A system for controlling delivery of purified water to the hemodialysis apparatus can comprise a therapy controller of the hemodialysis apparatus configured to communicate with a controller of a water purification device, and a user interface controller of the hemodialysis apparatus configured to communicate with the therapy controller, and to send data to and receive data from a user interface.
    • 配置为与远程服务器进行通信的医疗设备的处理器可以被编程以保护医疗设备不被暴露于未授权或恶意软件。 实现这种形式的保护的系统或方法可以包括例如医疗设备上的至少一个处理器,控制医疗设备的操作并且可以在处理器上执行的控制软件模块,管理 从医疗设备外部的来自控制软件模块的数据流,以及访问医疗设备中有限数量的指定存储器位置的代理模块。 此外,血液透析装置可以被配置为与用于从诸如城市供水或井的源提供净化水的装置一起操作。 用于控制向血液透析装置输送净化水的系统可以包括构造成与水净化装置的控制器通信的血液透析装置的治疗控制器,以及构造成与治疗控制器通信的血液透析装置的用户界面控制器, 并向用户界面发送数据并从用户界面接收数据。

    • A system for detecting whether a vascular access has been interrupted in an arrangement in which two catheters or needles are present in a blood vessel, fistula or graft. A fluid line leading to a pump is connected via a first connector to a first indwelling catheter, and a fluid line leading from a pump is connected via a second connector to a second indwelling catheter. Each connector is equipped with an electrode in contact with the lumen of the connector, the electrodes electrically connected to an electronic circuit that measures the impedance or conductivity of fluid between the first connector and second connectors via a fluid path through the blood vessel, fistula or graft. An electronic controller receives the impedance or conductivity data and processes the data to determine whether a vascular access disconnection has occurred. The processing may involve filtering the signal received by the controller, and/or setting provisional flags for a disconnection event that may be cleared if the signal changes before the expiration of a counter.
    • 用于检测在血管,瘘管或移植物中存在两个导管或针头的布置中血管通路是否被中断的系统。 通过泵的流体管线经由第一连接器连接到第一留置导管,并且从泵引出的流体管线经由第二连接器连接到第二留置导管。 每个连接器配备有与连接器的内腔相接触的电极,电极电连接到电子电路,该电子电路经由血管,瘘管或血管的流体路径测量第一连接器和第二连接器之间的流体的阻抗或导电性 接枝。 电子控制器接收阻抗或电导率数据并处理数据以确定是否发生血管通路断开。 处理可以包括过滤由控制器接收的信号,和/或设置用于断开事件的临时标志,如果信号在计数器期满之前改变,可以将其清除。
