Peristaltic pump and method for adjustable flow regulation
First Claim
1. A peristaltic pump for metering minute quantities of fluid comprising:
- (a) resilient peristaltic pump tubing having a first end and a second end;
(b) radial deforming means for radially deforming successive sections of said peristaltic pump tubing disposed intermediate said first end and said second end of said peristaltic pump tubing;
(c) positioning means for securing said first end of said length of peristaltic pump tubing;
(d) adjustable axial elongation means for axially elongating said length of peristaltic pump tubing disposed intermediate said second end and said radial deforming means; and
(e) a motor means for operating said radial deforming means.

Abstract
A peristaltic pump is provided having an adjustable flow regulation provided by an adjustable axial elongation apparatus 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 include 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 microprocessor for ascertaining and displaying the speed of the drive motor.
