Abstract
A linear peristaltic pump for pumping fluid through a resilient tube has a pair of pumping fingers, a pair of pinching fingers, and a strain gauge to monitor pressure inside the tube. The first pumping finger squeezes the tube at a first location, and the second pumping finger squeezes the tube at a second location. Additionally, the first pumping finger is configured and operated to displace approximately twice the fluid volume displaced by the second pumping finger. The first pinching finger occludes the tube upstream to the first pumping finger and the second pinching finger occludes the tube between the first and second pumping fingers. To monitor dimensional changes in the outer diameter of the tube and thereby indicate pressure inside the tube, the strain gauge is mounted on the pump between the second pinching finger and first pumping fingers. Finally, a leaf spring and photoelectric sensor are associated with the first pumping finger to indicate when the finger is in its fully withdrawn position.
