    • A flow regulating device and specifically an improved roller clamp with a length of conduit exhibiting low compression set properties disposed therein. The clamp includes an elongated box-like body having a fluid inlet at one end with a fluid outlet at the opposite end which are joined by the conduit to provide a flow lumen through the clamp. The roller is captured within a track in the body to selectively compress or release the conduit towards or away from a compression surface disposed at an angular variance to the track. The flow rate is regulated by appropriately positioning the roller. The conduit is captured within the body so as to be unaffected by external pulling or tugging forces.
    • 流量调节装置,特别是具有设置在其中的具有低压缩永久变形特性的导管长度的改进的辊夹。 夹具包括细长的盒状体,其一端具有流体入口,在相对端具有流体出口,其通过导管连接以提供通过夹具的流动腔。 辊被捕获在体内的轨道中,以选择性地压缩或释放导管朝向或远离以与轨道成角度变化设置的压缩表面。 通过适当地定位辊来调节流量。 管道被捕获在体内,以便不受外部牵引力或牵引力的影响。
