Abstract
An improved roller for peristaltic pumps includes a central portion and a plurality of projections extending radially outwardly from the central portion. The projections enable use of a roller having a larger diameter, while ensuring that the tube carrying the solution is effectively pinched off. The larger diameter roller provides a greater moment arm and decreases current draw. The small projections used to accomplish the seal also severely deforms a smaller amount of tubing and thus requires less current draw.
