  • Flow control device
    Patent number: 3960149
    Abstract: A flow control device for accurately regulating the flow of fluid through flexible tubing. A pivotal platen is employed in conjunction with a roller which upon rotation along an intersecting axis with a length of tubing will effect a squeezing or compressive action on the tubing but with the compressive force being applied over a wide area of the tubing so as to not effect a distortion of the tubing after the compressive force is discontinued. The flow control unit can be utilized as a clamp in that it can completely disrupt the flow of fluid through the tubing yet it is highy adapted to being used as a flow control device in conjunction with a parenteral administration set.
