Abstract
An infusion device (1) for administering a medical fluid to a patient (P) comprises a pumping mechanism (11) for exerting a force onto a delivery set (2, 3) for delivering a medical fluid from the delivery set towards a patient (P), a sensor device (14) for measuring the force exerted on the delivery set (2, 3) by the pumping mechanism (11), the sensor device (14) being constituted to output a sensor signal indicative of the force exerted onto the delivery set (2, 3), and a processor device (15) for controlling operation of the infusion device (1). Herein, the processor device (15) is constituted to perform a diagnosis routine during which a sensor signal of the sensor device (14) is obtained and compared to an expected sensor signal, to allow for detecting a drift in the sensor signal of the sensor device (14).
