ANALYTICAL DEVICE INCLUDING STERILE PROTECTION
First Claim
1. An analytical device comprising a lancet and a test element in an integrated arrangement, the lancet comprising a lancet needle with a tip and a protective cap which generally completely surrounds the lancet needle at least in the area of the tip, wherein the lancet needle can be displaced in at least one direction relative to the protective cap, and wherein the lancet needle is configured to engage the protective cap after displacement of the lancet needle in the at least one direction and thereafter to pull the protective cap during displacement of the lancet needle in a retracting direction, the test element comprising a chamber containing a reagent system, the chamber having a first opening configured to be generally sealed by the protective cap prior to and during displacement of the lancet needle in the at least one direction and configured thereafter to be generally opened upon displacement of the lancet needle in the retracting direction.

Abstract
An analytical device is provided comprising a lancet and a test element in an integrated arrangement. The lancet generally comprises a lancet needle and a protective cap wherein the lancet needle can be displaced relative to the protective cap and wherein the protective cap generally completely surrounds the tip of the lancet needle. The protective cap is typically comprised of an elastic or plastic material and is configured to generally seal an opening provided in a chamber of the test element. In certain embodiments, the lancet comprises a conductive material and can be configured for electrical connection to a detection and evaluation device in order to be used to measure the filling level of the sample liquid and/or to serve as a counter or reference electrode. The present invention also relates to a process for producing such an analytical device and the use thereof.

11. A method for producing an analytical device comprising the steps of:
- providing a lancet comprising a lancet needle and a protective cap, the lancet needle having a tip located in the protective cap the lancet further comprising a catching device provided on the lancet needle configured to pull the protective cap back along with the needle when the lancet is displaced in a retracting direction;
providing a test element comprising a chamber containing a reagent system and an opening in the chamber;
sterilizing the lancet; and
introducing the lancet into the chamber such that the protective cap seals the opening of the chamber.
- providing a lancet comprising a lancet needle and a protective cap, the lancet needle having a tip located in the protective cap the lancet further comprising a catching device provided on the lancet needle configured to pull the protective cap back along with the needle when the lancet is displaced in a retracting direction;
