Abstract
A peristaltic pump is provided having an adjustable flow regulation provided by an adjustable axial elongation means for the variable elongation of resilient tubing disposed between the associated rotors of a rotary peristaltic pump or the plurality of reciprocal pushers or fingers in a linear peristaltic pump to provide a radial compression of successive sections of the resilient tubing. The rotary or linear peristaltic pump includes a calibrated display and a variable speed electric motor having forward and reversing capabilities along with computer interface control for precisely metering and monitoring the volume of liquids for medical, biological and laboratory applications. Individual adjustable flow regulation is provided for each of the resilient tubes in the peristaltic pump by providing for the independent adjustable elongation of the flexible tubing in relation to the plurality of reciprocal pushers or fingers in the linear peristaltic pump or the associated rollers in a rotary peristaltic pump in combination with a means for ascertaining and displaying the speed of the drive motor.
