摘要：
A method for pumping a fluid includes providing a peristaltic pump including a contact wall, a movable compression element, and a flexible tube. The movable compression element opposes the contact wall. The contact wall and the compression element define a compressing region therebetween. The flexible tube is interposed between the contact wall and the compression element in the compressing region. The flexible tube has a tube lengthwise axis and inner and outer opposed wall surfaces. The inner wall surface defines a through passage to receive the fluid. The flexible tube is displaceable relative to the compressing region between a first position and a second position different from the first position. The method further includes: with the flexible tube in the first position, compressing the flexible tube between the compression element and the contact wall to thereby force the fluid through the through passage； thereafter displacing the flexible tube into the second position from the first position； and thereafter, with the flexible tube in the second position, compressing the flexible tube between the compression element and the contact wall to thereby force the fluid through the through passage.
