Abstract

The invention concerns lancets with a lancet needle, the tip of the lancet needle being embedded in an elastic material. Furthermore the invention concerns lancets where the tip of the lancet needle is surrounded by a hollow body which partially consists of an elastic material that can be pierced by the tip of the lancet needle during the lancing process and which reseals the tip of the lancet needle in the hollow body when it is retracted. In addition the invention concerns a lancet magazine in which the lancets are accommodated in individual chambers, each chamber having an opening through which the tip of the lancet needle can pass, which is sealed by an elastic material. Finally the invention concerns the use of an elastic material as a component of a lancet or a lancet magazine to maintain the sterility of at least the tip of a lancet needle in the unused state and to hygienically protect at least the tip of a lancet needle in the used state.
