摘要
The present invention comprises an apparatus for pumping fluid through tubing. The apparatus includes a tubing base having a tubing support surface and a stop platen. The stop platen and the tubing support surface each comprise respective ridges aligned with a direction of fluid flow through the apparatus. The respective ridges are operatively arranged to engage a wall of tubing along a longitudinal axis of the tubing. In some aspects, the respective ridges are arcuate in a plane orthogonal to the direction of flow. In some aspects, the respective ridges are centered with respect to a transverse axis of the tubing and have a respective width less than an outside diameter of the tubing.
