A peristaltic infusion pump is disclosed herein and includes a continuous tubular arrangement adapted to pass intravenous fluids therethrough and a peristaltic pump head mounted for rotation about a fixed axis. This pump head includes a plurality of innerconnected, circumferentially spaced tube engaging members adapted to successively engage the tubular arrangement during rotation for peristaltically pumping fluid therethrough. In a preferred embodiment, the pump includes a stepping motor which is energized in a particular way for rotating the pump head and which is also used to sense occlusion in the tubular arrangement. This preferred pump also includes a particular arrangement for detecting the index of refraction of the intravenous fluid for detecting the presence of air bubbles or the like.
