Problems solved by technology

In this case, the need to use hydrophilic materials severely limits the choice of suitable materials
Consequently, other material properties that also exert an influence on the functionality of the detection element are not to the desired extent
Functional coatings must be selected to meet very specific criteria, and this is the subject of an in-depth R&D activity, which is time-consuming and expensive
Also, coating application and process control measures during production are expensive
The application of a coating does provide a hydrophilic surface in the assay area of ​​the detection element, but this generally limits the durability and mechanical strength of the detection element

Embodiment Construction

[0019] Hereinafter, the present invention will be described in more detail through examples with reference to the accompanying drawings.

[0020] The only graph ( figure 1 ) schematically shows an analytical device 1 having an analytical device 2 and a device 3 for imparting hydrophilic properties. The analysis device 2 is configured to analyze a liquid sample to be assayed, which liquid is applied to the analysis region 4 of the detection element 5 , by means of a selected measurement or analysis technique suitable for a particular application. For example, the analysis device 2 is equipped with an optical measurement device with which measurement light can be directed towards the analysis region 4 . This enables identification, for example, of the fluorescence and / or absorption properties of the liquid being assayed. Depending on the application, the analysis device 2 can use one or more different measurement principles to determine the properties of the liquid sample.

Abstract

The invention relates to a device for the determination an analyte in a sample of liquid, in particular, a sample of a body fluid with an analysis apparatus which is configured to analyse a sample ofliquid after the latter has been applied to an analytical area of a test element prepared for an analysis of the sample of liquid and an apparatus conferring hydrophilic properties configured to confer hydkrophilic properties to a surface in the analytical area (4) for the preparation of the test element.

Description

technical field [0001] The present invention relates to a device and a method for determining an analyte in a liquid sample, especially a body fluid sample. Background technique [0002] Such devices and methods are used, for example, to determine one or more analytes in a sample of body fluid, especially a blood sample. In particular, known device forms are stationary and portable analytical instruments, such as laboratory instruments or hand-held instruments. In the so-called field of application for patient monitoring and care and treatment of diabetics, disposable detection elements, such as test strips, are frequently used for the determination of analytes in samples of body fluids. These detection elements are prepared for the determination of one or more analytes in bodily fluids or some other liquid samples particularly relevant to the appropriate field of analysis. To determine one or more analytes in a fluid sample, the bodily fluid sample is applied to the analy...
