Patent Images
1. A lancet system for withdrawing body fluid from a body part, comprising:
- a housing;
a lancet having a tip; and
a sterile protector that surrounds the tip, the sterile protector having a weakened portion that is brittle and is configured to undergo brittle fracture, the weakened portion of the sterile protector having a yield point of less than 50 N/mm2, the sterile protector at least partially separating along the weakened portion into sub-regions upon contact with the housing during a puncture movement, whereby the tip is released to perform a puncture.

Abstract
The present invention provides a lancet system having a lancet tip protected by a sterile protector. The sterile protector includes a weakened portion near the tip end of the protector, which, during a puncturing operation, separates or tears in order to release the lancet tip. Other embodiments of the present invention include a pricking aid and/or lancet system provided as a magazine for holding a plurality of lancets. Each lancet of the plurality has a sterile protector as described above.
