Abstract
Infusion device constituted to detect an abnormal condition during bolus injection An infusion device (1) for administering a medical fluid to a patient (4) comprises a pumping mechanism (12) for pumping a medical fluid through an infusion line (3) towards a patient (4), a sensor device (120) for measuring a measurement value indicative of a pressure in the infusion line (3), and a control device (13) being constituted to control the pumping mechanism (12) for injecting a bolus of medical fluid into the infusion line (3). Herein, the control device (13) is constituted to determine, dependent on an injection of a bolus into the infusion line (3), a control parameter taking a change in pressure during injection of the bolus into account and to derive, from the control parameter, the presence of an abnormal condition during the injection of the bolus. In this way an infusion device is provided which in a reliable manner allows for the detection of an abnormal condition during the administration of a bolus.
