    • A peritoneal dialysis system of the continuous flow type includes a reverse osmosis unit which prepares sterilized and filtered water. The process, which may be used with a single or double catheter, includes proportioning water, dialysis-concentrate, and dextrose to provide a dialysis fluid which is then heated and sterilized. The fluid may be accumulated in a reservoir. Load cells and/or flowmeters are utilized to measure the flow rate of the fluid in and out of the peritoneal cavity, either simultaneously or cyclic, and control the amount of fluid in the cavity. Preferably, the process and system includes a double flow catheter in which the flow of dialysis fluid through the inflow passage and the outflow passage are simultaneous. During this time, the volume of fluid in the peritoneal cavity is monitored by an ultrasonic or other suitable sensor so that over extension of the cavity does not occur. In a preferred tidal dialysis regime, a desired number of fill and partial drain cycles are performed wherein a puddle of dialysis fluid always remains in the cavity.
    • 连续流式的腹膜透析系统包括反渗透单元,其制备灭菌和过滤的水。 可以与单导管或双导管一起使用的方法包括配水,透析浓缩物和右旋糖,以提供透析液,然后将其加热灭菌。 流体可以积聚在储存器中。 负载传感器和/或流量计用于测量流体进出腹腔的流速,同时或循环,并控制空腔中的流体量。 优选地,该方法和系统包括双流导管,其中通过流入通道和流出通道的透析流体的流动是同时的。 在此期间,通过超声波或其它合适的传感器监测腹膜腔中的流体体积,以致不会发生腔的过度延伸。 在优选的潮汐透析方案中,执行所需数量的填充和部分排水循环,其中透析液的水坑总是保留在空腔中。
