The invention proposes a medical system which comprises a central control unit which is set up to display at least one diagnostic measured value using a display element. The medical system also comprises at least one invasive unit, wherein the invasive unit has at least one invasive consumable. The invasive consumable is set up to invasively intervene in a tissue of a patient. The invasive unit has at least one contactlessly readable electronic identifier for storing at least one piece of information. The central control unit is set up to electronically read the at least one piece of information in the electronic identifier. The central control unit and the invasive unit are functionally independent of one another such that the respective function of the central control unit and of the invasive unit can be performed independently of the presence of the respective other unit.

A diagnostic test tape for liquid samples is provided comprising a flexible transport tape and a plurality of test fields applied to the transport tape that are distributed in the longitudinal direction of the tape, where said test fields comprise a detection layer and a spreading net spanning the detection layer for a planar uptake of liquid sample, wherein the spreading net is formed from a lattice-like fabric comprising fabric threads that cross at right angles. In order to prevent the fabric from arching up under tape tension it is proposed that the fabric is oriented obliquely to the transport tape such that all fabric threads run obliquely to the longitudinal direction of the tape.

Disclosed is a process for manufacturing packaged lancets. The steps of the process include providing a tape comprising a plurality of lancets comprising a lancet tip and a lancet body, enveloping at least the lancet tip with at least one foil, whereby the at least one foil forms a first and a second portion that overlap at least partly, and sealing the at least one foil with a laser beam at least at the edges of the first and second portion of the overlapping foil.

A method is provided for producing an analytical element comprising at least one test field for analyzing a liquid sample, wherein provision is made for a carrier on which a polymer fabric is arranged. At least one portion of the polymer fabric is irradiated with UV laser light and thereby hydrophobized.

Method for the production of an analytical element

The invention relates to a method for production of a multi-layer analysis element for liquid samples, with at least one test field for the analysis of the liquid samples, in which method an analysis element blank composed of at least two superposed material layers is made available. The multi-layer analysis element or a constituent part of the multi-layer analysis element is cut out from the analysis element blank by means of laser radiation. The laser radiation cuts through different material layers in at least two areas and has a laser power which is effective for the cutting and which is varied as a function of the thickness and the material of the different material layers to be cut in the areas.

The invention concerns a microdialysis system comprising a microdialysis probe ( ) that can be inserted into organic tissue ( ) and has a dialysis membrane ( ) to separate a probe channel ( ) filled with perfusion fluid from the tissue ( ), a sensor cell ( ) to determine the concentration of components and especially glucose in the perfusion fluid that is conveyed from the microdialysis probe ( ) and a transport device ( ) to convey the perfusion fluid through the probe channel ( ) of the microdialysis probe ( ) to the sensor cell ( ). In order to enable a substantially pressureless transport of perfusion fluid through the microdialysis probe and thus to prevent undesired passage of fluid through the dialysis membrane ( ), it is proposed that the transport device ( ) has a pressure pump unit ( ) connected on the pressure side to the inlet ( ) of the probe channel ( ) and a suction pump unit ( ) connected on the suction side to the outlet ( ) of the probe channel ( ) that can be operated simultaneously with the pressure pump unit ( ).
