Abstract

A curvilinear peristaltic pump (10) includes a rotatable cam (34) coupled to a drive unit (36) in a housing (16) having a platen member (26). Activation of the drive unit (36) rotates the cam (34) in a first direction and the deactivation of the drive unit (36) maintains the cam in a set position. The cam (34) moves a plurality of pump fingers (52) radially outwardly toward and radially inwardly away from the platen member (26). The pump (10) is used in conjunction with a disposable tubing assembly (12) which is provided with a shut-off valve (14) to selectively obstruct the flow of liquid through the tubing assembly (12).
