1. A method of pumping fluid through a flexible tubing and of reshaping said tubing during said pumping, comprising the steps of:

  • (a) releasably engaging said flexible tubing;

    (b) reciprocating each of a plurality of pumping elements sequentially between compression and release of said flexible tubing along a length thereof so that fluid is pumped therethrough;

    (c) actuating each of a plurality of reshaping fingers sequentially with reshaping contact against said tubing, corresponding to release thereof by adjacent ones of said plurality of pumping elements; and

    (d) interdigitatedly disposing each of said plurality of pumping elements between pairs of said plurality of reshaping fingers so that non-collapsing reshaping of said tubing sequentially results adjacent to said pumping elements, on either side thereof.
