Abstract
An automatically operating injection device with an occlusion alarm unit and a method for determining an injection occlusion are disclosed. The method includes generating a plurality of evaluation forces based on a series of force measurements and based on an evaluation time period; determining whether an occlusion exists based on either an evaluation of the plurality of evaluation forces or whether one or more of the series of force measurements exceeds a force threshold; and providing an injection occlusion alarm if an occlusion is determined to exist.
