Abstract: An occluder detection system is disclosed. At least one occluder element moves according to a cam motion to apply a periodic compression to a flexible infusion line. A portion of the occluder element is configured to emit or modify an energy or magnetic field. A sensor is configured to measure the energy being emitted or modified by the section of the occluder element. A processor causes the at least one occluder element to move according to the cam motion to move a fluid within the flexible infusion line by periodically compressing the flexible infusion line, measures the energy of the energy source via the sensor, obtains a current cam state associated with the cam motion at a time corresponding to the measured energy, and determines, based on the measured energy and the current cam state, a state of the occluder element. The processor may issue an alarm on a fault condition.
