ABSTRACT:
A unitarily constructed clamp for selectively occluding a resilient tube includes a curved platen formed with a pair of holes through which the tube is threaded to position and hold the tube against the concave surface of the platen. The platen has a first end and a second end. Additionally, an articulated pressure member having a hinged juncture is pivotally connected to both the first end and the second end of the platen to locate the juncture between the ends of the platen. With this configuration, the articulated pressure member is positioned for movement between an open configuration and a closed configuration. In the open configuration, the pressure member is distanced from the platen to leave the tube patent. In the closed configuration, the tube is squeezed between the platen and the pressure member to occlude the tube.
