MEASUREMENT HEAD FOR NON-INVASIVE BLOOD ANALYSIS

摘要

The present invention provides an efficient approach of attaching and fixing a measurement head for a spectroscopic system to a variety of different parts of the skin of a patient. The measurement head preferably features a compact design providing a flexible handling and offering a huge variety of application areas taking into account the plurality of properties of various portions of the skin. Furthermore, the measurement head features a robust and uncomplicated optical design not requiring a lateral shifting of the optical axis of the objective. Such transverse relative movements between the objective and a capillary vessel in the skin are preferably performed by mechanically shifting the skin with respect to the objective of the measurement head. Moreover, the measurement head is adapted to host one or more pressure sensors measuring the contact pressure between the measurement head and the skin. This pressure information can further be exploited in order to calibrate the spectroscopic analysis means, to regulate the contact pressure within predefined margins specifying an optimum range of contact pressure for spectroscopic examination of capillary vessels.
