An infusion apparatus for delivering medication includes a housing, a drive mechanism, a force sensor, and a transfer element. The drive mechanism comprises first and second conveying elements, the second conveying element for advancing a plug in a reservoir in the distal direction, the first conveying element with limited axial movement relative to the housing but rotatable to cause an ejecting or resetting movement of the second conveying element. The force sensor is arranged along a central axis between the housing and the proximal end of the drive mechanism. The transfer element is axially arranged between the force sensor and the first conveying element and the force sensor bears axial forces exerted by the ejection movement. The second conveying element moves the transfer element away from the first conveying element against the bias of a restoring force such that the force sensor bears axial forces exerted by the resetting movement.
