Abstract
A change in the internal pressure of the fluid-infusion tube of a peristaltic fluid-infusion pump due to occlusion in the fluid-infusion tube is detected through a change in the diameter of the fluid-infusion tube. The occlusion is detected by detection of the change in the distance between the opposite wall portions of the tube.
