Abstract

An infusion device (3) comprises a housing element (30) having a receptacle (301) for receiving a pump module (1), and a pump actuation mechanism (2) having a wobbling device (20) arranged on the housing element (30) and a drive shaft (21) being rotatable about a rotational axis (A). The wobbling device (20) is actuatable, by rotating the drive shaft (21) about the rotational axis (A), to perform a tumbling motion with respect to the receptacle (300) for acting onto the pump module (1) received in the receptacle (300) in order to pump a fluid through the pump module (1). Herein, the wobbling device (20) is displaceable along at least one direction (X, Y) transverse to the rotational axis (A) with respect to the receptacle (300). In this way an infusion device is provided which in an easy and cost-efficient manner allows for improving the positional accuracy of the pump module with respect to the wobbling device of the pump actuation mechanism upon arranging the pump module on the receptacle of the housing element.
