Abstract
A large bore tubing roller clamp assembly for regulating the flow rate of a liquid through large bore tubing is disclosed. The roller clamp assembly comprises a substantially rigid elongated plastic frame, a generally cylindrical roller, and a length of a large bore tubing disposed within the frame. The flow rate through the tubing is controlled by moving the roller along an inclined roller track and over the tubing, thereby selectively compressing tubing to attain the desired flow rate.
