    • A system for distending body tissue cavities of subjects by continuous flow irrigation during endoscopie procedures, the system including: a fluid source reservoir containing a non viscous physiologic fluid meant for cavity distension; a fluid supply conduit tube connecting the fluid source reservoir to an inlet port of a variable speed positive displacement inflow pump and an outlet port of the said inflow pump being connectable to an inflow port of an endoscope instrument through an inflow tube for pumping the fluid at a controlled flow rate into the cavity, the flow rate of the said inflow pump being termed as the inflow rate; an inflow pressure transducer being located anywhere in the inflow tube between the outlet port of the inflow pump and the inflow port of the endoscope; an outflow port of the endoscope being connectable to a waste fluid collecting container via a waste fluid carrying tube, and characterized in that an active inflow pressure pulsation dampening means is connected to the inflow tube for dampening the pressure pulsations inside the cavity created by the positive displacement inflow pump.
    • 一种用于在内窥镜程序期间通过连续流动灌注来增加受试者的身体组织腔的系统,所述系统包括:含有用于腔膨胀的非粘性生理液的流体源储存器; 将流体源储存器连接到变速正排量流入泵的入口和所述流入泵的出口的流体供应管道,其可通过流入管连接到内窥镜器械的流入口,用于将流体泵送 进入空腔的受控流速,所述流入泵的流量被称为流入速率; 流入压力传感器位于流入管的出口与内窥镜的流入口之间的入口管的任何位置; 所述内窥镜的流出口经由废液输送管可连接到废液收集容器,其特征在于,主动流入压力脉动阻尼装置连接到所述流入管,用于阻尼所述空腔内产生的压力脉动 排量流入泵。
