  • Patent number: 4856972
    Abstract: A peristaltic pump for infusing medical solutions to a patient through a flexible tube comprises a pair of counter-rotating drive shafts mounted on a base. A separate roller is eccentrically mounted on each of the drive shafts and each roller has a wheel which is slidingly suspended at its periphery. A pair of curvilinear platens are each separately disposed concentric with a respective drive shaft to engage the tube between the wheel on each roller and the platen. Cooperative counterrotation of the drive shafts cause each roller to sequentially squeeze the tube against its respective platen to create a moving zone of occlusion along the tube.
