DEVICE FOR ISOLATING REGIONS OF LIVING TISSUE

摘要

A device and method are provided for use with a non-invasive optical measurement system. A site selector (100) is secured to a patient's forearm, such as by a fastening strap (112), thereby isolating a measurement site on the patient's skin for determination of blood glucose levels. The site selector attaches to a thermal mass window of the spectrometer and thus forms an interface between the patient's skin and the thermal mass window. Protrusions (108, 108') and raised sections (110, 110') can facilitate the attachment. When the spectrometer must be temporarily removed from the patient's skin the site selector is left secured to the forearm so as to maintain a consistent measurement site on the skin. When the spectrometer is later reattached to the patient, the site selector will again form an interface between the gradient spectrometer and the same location of skin as before.
