Abstract
The invention relates to a drive unit for a medical device such as an insulin pump, lancing device, or test strip magazine. The drive unit comprises an actuator for charging a mechanical energy storage element. The actuator oscillates and executes travel strokes which are transmitted by means of a step-up element to a nonreturn rotor or traveler for prestressing the mechanical energy storage element and driving a movement element.
