<P>PROBLEM TO BE SOLVED: To provide a miniaturized optical analytical system which can continuously analyze body fluid of a patient. <P>SOLUTION: The sensor section has a hollow space extending from the distal end to the proximal end, wherein a needle array having at least one hollow needle suitable for lancing at the distal end. The proximal end of the needle is opened into a chamber in which liquid that enters through the distal end of the needle can be collected. A window which can be at least partially permeable to an infrared ray comes in direct contact with the chamber. By this sensor, the component concentration in body fluid can be measured based on the principle of ATR (attenuated total reflection). <P>COPYRIGHT: (C)2007,JPO&INPIT |
