Abstract

Abstract For simultaneous recording of the concentration of different analytes at several points of a tissue by means of a thin, biocompatible flexible or rigid tube that can be inserted into a tissue the invention proposes that the flexible tube (2) has several regions (3, 4, 5...) over its axial extension. The regions are each provided with identical or different, optically excitable and readable, preferably luminescence optical indicator substances for measuring the local distribution of a parameter, for example the O2 concentration or the O2 partial pressure, or for simultaneously measuring at least two different parameters, for example from among the group of pO2, pCO2 and pH. <IMAGE>
