Abstract
A lancing apparatus for producing a puncture wound, comprising a magazine holder for a lancet magazine with a plurality of lancets. The lancet drive comprises a drive spring, a tensioning device for tensioning the drive spring and a push rod, the push rod being adapted for coupling to a lancet located in the lancet magazine and being adapted for moving at high velocity, together with a lancet coupled thereto, by means of lancet drive during a puncture and retraction movement to produce a puncture wound. A magazine advancing mechanism is provided for advancing the lancet magazine in such a manner that the lancets stored therein can be coupled to the push rod one after the other. According to exemplary embodiments, the lancet drive is not mechanically coupled to the magazine advancing mechanism whereby a plurality of puncture wounds can be produced using the same lancet a plurality of times. The lancing apparatus compromises an actuating element for actuating the magazine advancing mechanism independently from the lancet drive, in particular for actuating it independently from the tensioning device.
