1. A lancet magazine, comprising:
- a plurality of lancets for generating a puncture wound for collection of a sample of a body fluid;
each lancet having a respective drive mechanism coupled thereto, each drive mechanism comprising at least one pretensioned drive element which releases mechanical energy to accelerate the respective coupled lancet for a puncturing movement when the drive mechanism is triggered; and
each drive mechanism comprising a drive arm which carries its respective lancet and which moves from a bent starting position to a stretched position during an advancing phase of a puncturing movement.

Abstract
The invention relates to a lancet magazine with a plurality of lancets for generating a puncture wound for collecting a sample of body fluid. According to the invention, the lancets in the lancet magazine are each coupled to a drive mechanism which, for each lancet, comprises at least one pretensioned drive element which, when the drive mechanism is triggered, releases mechanical energy to accelerate the lancet coupled thereto for a puncturing movement.

11. A puncturing system, comprising:
-
a housing in which a plurality of lancets are arranged; each lancet having a respective drive mechanism coupled thereto, each drive mechanism comprising at least one pretensioned drive element which releases mechanical energy to accelerate the respective coupled lancet for a puncturing movement when the drive mechanism is triggered; and each drive mechanism comprising a drive arm which carries its respective lancet and which moves from a bent starting position to a stretched position during an advancing phase of a puncturing movement.

12. A method of using a puncturing system having a plurality of lancets, each lancet having a respective drive arm coupled thereto, the method comprising:
-
(a) moving the drive arm of a first one of the lancets from a bent starting position to a stretched position and thereby performing an advancing phase of a puncturing movement during which the drive element releases mechanical energy to accelerate the respective coupled lancet; (b) positioning a second one of the lancets in an active position of the puncturing system; and (c) repeating step (a) with a second one of the lancets. - View Dependent Claims (13, 14)
