Abstract
An infusion device includes a pump for pumping a medical fluid from a fluid container through a delivery line towards a patient at a flow rate, a sensor for measuring a force on the pump or the delivery line, and a processor device configured to derive, from the force measured by the sensor, a pressure value indicative of the pressure in the delivery line and to compare the pressure value to a threshold value for determining whether an occlusion in the delivery line is present. A storage device stores a compliance value associated with the pump and/or the delivery line, and the processor device is configured to compute, from the stored compliance value, the flow rate and the threshold value, an estimate of a duration between the time of an occurrence of an occlusion and the time at which the pressure value exceeds the threshold value.
