Abstract
The invention concerns a detector for detecting malfunction in a peristaltic pump wherein a flexible tubing (44) containing a fluid is locally compressed against a support part by rollers (32) mounted on a rotor (28) driven by a motor. Said detector is characterized in that it comprises: a ring (68) mounted sliding on the tubing between two extreme positions; driving means (64, 80, 84), actuated by the rotor, for subjecting said ring to a specific reciprocating motion between said positions; and detection means (74a, 74b, 84) reacting to an abnormal reciprocal motion by producing a warning signal.
