Analytical device with integrated lancet
First Claim
1. An analytical device for collecting and examining a body fluid comprising:
- a test element including a frame element defining a plane and a detection element connected to the frame element, and a lancet including a needle having a tip and a lancet body at least partially surrounding the needle, the lancet body being movably connected to the frame element such that the lancet can adopt a storage position wherein the needle is aligned essentially parallel to the plane of the test element and a lancing position wherein the needle is aligned essentially orthogonal to the plane of the test element.

Abstract
The invention describes an analytical device (1) which is suitable for collecting and examining body fluids and in particular blood. The analytical device (1) contains a test element (2) and a lancet (3) whereby the test element (2) contains the following components: 1.) a frame element (7), and 2.) at least one detection element (6) which can also be multilayered and can contain among others an erythrocyte separation layer, a spreading layer and an optical barrier layer which is directly or indirectly connected to the frame element (7) and the lancet (3) contains the following components: 1.) a needle (11) with a tip (23) and 2.) a lancet body (10) which at least partially surrounds the needle (11). The inventive device (1) is characterized in that the lancet body (10) is movably connected to the frame element (7) of the test element (2) i.e. it can be folded or swung out such that the lancet (3) can adopt a storage position and a lancing position, the needle (11) being aligned in the storage position essentially parallel to the plane of the test element (2) and aligned in the lancing position essentially orthogonal to the plane of the test element (2).
