Abstract
A tubular conduit formed of resilient, flexible, thermoplastic material having an intermediate portion with at least one enlarged section that has a flow passage of substantially greater cross-sectional area, and a wall portion of lesser thickness and lower resistance to deformation, than found in the remainder of the conduit. The method of making the collapsible conduit, involving the steps of reshaping a preformed thermoplastic tube by molding it under heat and internal pressure, and the utilization of such a formed conduit in a linear peristaltic pump, are also disclosed.
