Abstract
An infusion device (1) for administering a medical fluid to a patient comprises a housing (10), a receptacle (11) arranged on the housing (10) for receiving a syringe (2), a syringe driver (12) movable in a driving direction (P) for acting onto a piston (21) of a syringe (2) received on the receptacle (11), and a drive mechanism (13) for electromotively driving the syringe driver (12) along the driving direction (P), the drive mechanism (13) comprising an electric drive motor (14) and a rotatable drive element (18) operatively coupled to the syringe driver (12) for moving the syringe driver (12) along the driving direction (P). Herein, the drive mechanism (13) comprises a clutch device (16) configured, in a coupled state, to couple the drive device (14) to the drive element (18) such that the drive device (14) is operative to drive the drive element (18) and, in an uncoupled state, to uncouple the drive device (14) from the drive element (18).
