Abstract
A pump hose for a peristaltic pump consists of two arcuate portions that merge along kink lines so that the undeformed hose lumen has the cross-sectional shape of a convex lens. The joinings of the arcuate portions are joined by outwardly extending ribs. When the hose is pressed, only minor squeezing occurs at the joinings. The hose has a considerably improved squeezing and restoring behavior. The ribs prevent an excessive squeezing.
