Abstract:
1. A lancing apparatus for producing a puncture wound, comprising: a housing a magazine holder disposed in the housing and configured to hold a lancet magazine having a plurality of lancets; a lancet drive comprising a drive spring, a tensioning device for tensioning the drive spring, and a push rod which couples to a lancet located in the lancet magazine and moves lancet in a puncture movement and a retraction movement the magazine holder being positioned in front of the lancet drive along the direction of the puncture movement; a magazine advancing mechanism for advancing the lancet magazine; and an actuating element configured to actuate the magazine advancing mechanism independently from the tensioning device; wherein the lancets stored in the magazine can be coupled to the push rod one after another; the lancet drive is not coupled to the magazine advancing mechanism, whereby the same lancet coupled to the push rod can be driven by the lancet drive in the puncture and retraction movements several times to produce several puncture wounds without advancing the lancet magazine; the magazine advancing mechanism is configured to advance the lancet magazine in only one direction; and the magazine advancing mechanism comprises a rotation limitation device for restricting the rotation of the lancet magazine to less than 360°.
