Disposable diagnostic part and a method for the manufacture thereof
First Claim
1. Disposable diagnostic part comprising a lancing element which is designed for puncturing the skin and has a laterally open collecting channel for taking up body fluid, and comprising a detection element which has a test layer provided with reagents for the detection of an analyte in the body fluid and is disposed in the collecting channel, characterized in that the detection element is provided with a sealing layer which is applied to the test layer and covers the reagents, wherein the sealing layer is distinct from the reagents, wherein the sealing layer is disposed in the collecting channel, wherein the sealing layer seals the reagents from an outside environment and prevents particles of reagent detaching from the test layer, wherein the lancing element has a tip for puncturing the skin, wherein the sealing layer is provided over the test layer and is located between the reagent and the tip.

Abstract
The invention concerns a disposable diagnostic part comprising a lancing element (14) which is designed for puncturing the skin (26) and has a collecting channel (16) for taking up body fluid, and comprising a detection element (18) which has a test layer (42) provided with reagents for the detection of an analyte in the body fluid and is disposed in the collecting channel (16). In order to ensure an improved stability and biocompatibility it is proposed that the detection element (18) is provided with a sealing layer (20) that is applied to the test layer (42) and covers the reagents.

- 15. Disposable diagnostic part comprising a lancing element which is designed for puncturing the skin and has a laterally open collecting channel for taking up body fluid, and comprising a detection element which has a test layer provided with reagents for the detection of an analyte in the body fluid, characterized in that the detection element is at least partially provided with a sealing layer formed from non-ionic surfactants, wherein the sealing layer is distinct from the test layer, wherein the sealing layer completely covers the test layer such that a margin surrounding the test layer is covered by the sealing layer to prevent detachment of particles of the reagent, wherein the sealing layer is located so that the body fluid contacts the sealing layer before contacting the test layer, wherein the sealing layer is dissolvable when the collecting channel is filled by body fluid so that the analyte comes into contact with the reagents.
