Abstract: Disclosed is an infusion pump (400, 600) for expelling a fluid from a collapsible fluid reservoir (406, 640) to a patient. The pump (400, 600) includes a housing (401, 601) having a chamber (446, 646) therein for receiving the fluid reservoir (406, 640). A first wall (404, 604) is provided on the housing for contacting the fluid reservoir (406, 640), and a second wall (410, 630) is movable from a first position distanced from the first wall to form the chamber therebetween, and a second position relatively closer to the first wall. Advancing the movable wall (410, 630) from the first position to the second position expels fluid from the collapsible reservoir (406, 640) at a substantially constant rate by applying increasing force on the fluid reservoir (406, 640) through the dispensation cycle. Preferably, the first and second walls (406, 410, 604, 630) are provided with non-planar complementary surface (408, 413, 415, 417) for contacting the collapsible reservoir (406, 630).
