ABSTRACT:
The invention is a pumping system composed of a relatively thin wall extruded tubing that in different forms can provide flow regulation for peristaltic pumps, reduce spallation, extend pumping life, provide means to measure inlet and outlet pressure of the peristaltic pump and limits the inlet and outlet pressure generated by peristaltic pumps, and a special peristaltic pump that takes advantage of the characteristics of the aforementioned tubing. The invention has particular usefulness in the medical industry for pumping physiological or nutritional liquids.
