Abstract
A method for controlling the flow rate of a peristaltic pump includes compressing a flexible tube, forming at least one occlusion region that moves cyclically downstream from the upstream end of the pump, and compressing the tube in the direction of a counter surface to form an occlusion. A peristaltic pump can be used to carry out the method so as to suppress reverse flow without altering the speed of the motor. The occlusion in the most downstream part of the pump remain in the occluding position for a longer portion of the cycle than the occlusion in a more upstream part of the pump, preferably for longer than the compression in the most upstream part of the pump.
