摘要:
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 pusher device (12) movable in a pushing direction (P) for acting onto a piston (21) of a syringe (2) received on the receptacle (11); a drive element (13) connected to the pusher device (12), the drive element (13) being longitudinally movable relative to the housing (10) for moving the pusher device (12) along the pushing direction (P); a driving rod (14) having a screw thread (140) and being rotatable about a rotational axis (R1); an electric drive device (141) for rotating the driving rod (14); a clutching device (130) connected to the drive element (13) and being actuatable, by an actuation device (15), to engage, in a clutched state, with the screw thread (140) of the driving rod (14) for translating a rotational movement of the driving rod (14) into a longitudinal movement of the drive element (13) along the driving rod (14), and to disengage, in an unclutched state, from the driving rod (14); a brake device (16) constituted to act, in an activated state, onto the drive element (13) for braking the drive element (13) relative to the housing (10) and to allow, in a deactivated state, a longitudinal movement of the drive element (13) relative to the housing (10); a control device (17) to control the electric drive device (141) and the brake device (16); and a sensing device (170) for detecting an actuation state of the clutching device (130). Herein, the control device (17) is constituted, when the sensing device (170) detects that the clutching device (130) is actuated to change from the unclutched state to the clutched state, to perform a control sequence during which the control device (17) controls the electric drive device (141) to rotate the driving rod (14) for a predetermined duration or for a predetermined angle of rotation while the brake device (16) is in the activated state.La
