This invention discloses a peristaltic pump composed of a two-stage linear peristaltic pump mechanism, which engages in different functions, charging and pumping a fluid to a patient. This peristaltic pump is capable of restoring the crushed tubing, caused by repeated compression or crushing of the tubing by peristaltic fingers, to its original circular cross sectional area so that it can provide a precise flow rate. The two-stage linear peristaltic pump mechanism substantially improves the consistency of a flow rate over time and extends the usefulness of peristaltic pumps to applications where they could not otherwise be used.
A peristaltic pump configured to act on a piece of tubing in fluid communication with a reservoir containing a fluid, the peristaltic pump comprising a two-stage linear peristaltic pump mechanism, wherein one stage of the two-stage linear peristaltic pump mechanism ensures a crushed area of the tubing on which the other stage of the two-stage linear peristaltic pump mechanism operates is returned to an original cross sectional area and to provide a consistent flow rate of the fluid through said piece of tubing.
