Abstract
Analysis device for determining an analyte in vivo in the body of a patient, having a measuring probe with a hollow needle ( ) which can pierce through the skin. Light is passed through the hollow needle ( ) and into the body via an optical fiber ( ) travelling in the hollow needle ( ). The light transported in the optical fiber ( ) is modified in the measuring probe ( ), the modification being characteristic of the presence of the analyte. A measurement and evaluation unit ( ) measures the change to extract information concerning the presence of the analyte in the body. The hollow needle ( ) is permeable, at least in a partial section of its length, serving as a measuring section ( ) which can be inserted into the skin so that interstitial liquid may penetrate through the hollow needle wall to a measuring section of the optical fiber extending in the hollow needle ( ) and the modification of the light characteristic of the presence of the analyte is effected through interaction with the interstitial liquid in the measuring section.
